Increase the firefox speed

Firefox 1.5 and above, including Firefox 2.0.x limits the amount of time that a script or Javascript took to run and complete.
Whenever a web page takes too long to load, an error will pop up with the following message:
Warning : Unresponsive scriptA script on this page may be busy, or it may have stopped responding.
You can stop the script now, or you can continue to see if the script will complete.Firefox Unresponsive Script
Users have two option buttons namely Stop Script or Continue.
Pressing Continue will likely to make the Firefox browser to remain sluggish or not responding, while Stop Script will inevitably cause part of the website depends on script not functioning properly, such as Java script menu, auto refresh or update of streaming live contents.If you click on Continue, and yet script is still hanging, you will keep getting the Unresponsive Script error dialog again and again once the the preset maximum script running time hit, which is default to 5 seconds in Firefox 1.5 and 10 seconds in Firefox 2.
To get rid of the annoying Unresponsive Script error dialog and fix the behavior of script that takes long execution time in Firefox, we can longer the waiting time for script to run before Firefox intercept it with warning.
1.Run Firefox.
2. In the Firefox address bar, type about:config, and then press Enter.
3. Scroll and locate or search with Filter text box for dom.max_script_run_time.
4. Double click on the line of dom.max_script_run_time, and change the value to a higher number (in seconds) that you want Firefox to wait before getting the Unresponsive Script warning.
Be default, the value is 5 or 10 seconds. You can safely set the magical number to let’s say 20. You can set the value to 0 to instruct Firefox to wait foever - no warning and dialog whatsoever.
Note that the whole Firefox may be not responsive and cannot be used while waiting for scripts to execute, so the number should not set too high in order to give you an opportunity to stop truly nasty or buggy scripts and recover use of Firefox.
5. Click OK.
6. Restart Firefox.

15 Coolest Firefox Tricks

15 Coolest Firefox Tricks Ever
Everybody’s favorite open-source browser, Firefox, is great right out of the box. And by adding some of the awesome extensions available out there, the browser just gets better and better.
But look under the hood, and there are a bunch of hidden (and some not-so-secret) tips and tricks available that will crank Firefox up and pimp your browser. Make it faster, cooler, more efficient. Get to be a Jedi master with the following cool Firefox tricks.
1) More screen space. Make your icons small. Go to View - Toolbars - Customize and check the “Use small icons” box.
2) Smart keywords. If there’s a search you use a lot (let’s say IMDB.com’s people search), this is an awesome tool that not many people use. Right-click on the search box, select “Add a Keyword for this search”, give the keyword a name and an easy-to-type and easy-to-remember shortcut name (let’s say “actor”) and save it. Now, when you want to do an actor search, go to Firefox’s address bar, type “actor” and the name of the actor and press return. Instant search! You can do this with any search box.
3) Keyboard shortcuts. This is where you become a real Jedi. It just takes a little while to learn these, but once you do, your browsing will be super fast. Here are some of the most common (and my personal favs):
* Spacebar (page down)* Shift-Spacebar (page up)* Ctrl+F (find)* Alt-N (find next)* Ctrl+D (bookmark page)* Ctrl+T (new tab)* Ctrl+K (go to search box)* Ctrl+L (go to address bar)* Ctrl+= (increase text size)* Ctrl+- (decrease text size)* Ctrl-W (close tab)* F5 (reload)* Alt-Home (go to home page)
4) Auto-complete. This is another keyboard shortcut, but it’s not commonly known and very useful. Go to the address bar (Control-L) and type the name of the site without the “www” or the “.com”. Let’s say “google”. Then press Control-Enter, and it will automatically fill in the “www” and the “.com” and take you there - like magic! For .net addresses, press Shift-Enter, and for .org addresses, press Control-Shift-Enter.
5) Tab navigation. Instead of using the mouse to select different tabs that you have open, use the keyboard. Here are the shortcuts:
* Ctrl+Tab (rotate forward among tabs)* Ctrl+Shft+Tab (rotate to the previous tab)* Ctrl+1-9 (choose a number to jump to a specific tab)
6) Mouse shortcuts. Sometimes you’re already using your mouse and it’s easier to use a mouse shortcut than to go back to the keyboard. Master these cool ones:
* Middle click on link (opens in new tab)* Shift-scroll down (previous page)* Shift-scroll up (next page)* Ctrl-scroll up (decrease text size)* Ctrl-scroll down (increase text size)* Middle click on a tab (closes tab)
7) Delete items from address bar history. Firefox’s ability to automatically show previous URLs you’ve visited, as you type, in the address bar’s drop-down history menu is very cool. But sometimes you just don’t want those URLs to show up (I won’t ask why). Go to the address bar (Ctrl-L), start typing an address, and the drop-down menu will appear with the URLs of pages you’ve visited with those letters in them. Use the down-arrow to go down to an address you want to delete, and press the Delete key to make it disappear.
User chrome. If you really want to trick out your Firefox, you’ll want to create a UserChrome.css file and customize your browser. It’s a bit complicated to get into here, but check out this tutorial.
9) Create a user.js file. Another way to customize Firefox, creating a user.js file can really speed up your browsing. You’ll need to create a text file named user.js in your profile folder (see this to find out where the profile folder is) and see this example user.js file that you can modify. Created by techlifeweb.com, this example explains some of the things you can do in its comments.
10) about:config. The true power user’s tool, about.config isn’t something to mess with if you don’t know what a setting does. You can get to the main configuration screen by putting about:config in the browser’s address bar. See Mozillazine’s about:config tips and screenshots.
11) Add a keyword for a bookmark. Go to your bookmarks much faster by giving them keywords. Right-click the bookmark and then select Properties. Put a short keyword in the keyword field, save it, and now you can type that keyword in the address bar and it will go to that bookmark.
12) Speed up Firefox. If you have a broadband connection (and most of us do), you can use pipelining to speed up your page loads. This allows Firefox to load multiple things on a page at once, instead of one at a time (by default, it’s optimized for dialup connections). Here’s how:
* Type “about:config” into the address bar and hit return. Type “network.http” in the filter field, and change the following settings (double-click on them to change them):* Set “network.http.pipelining” to “true”* Set “network.http.proxy.pipelining” to “true”* Set “network.http.pipelining.maxrequests” to a number like 30. This will allow it to make 30 requests at once.* Also, right-click anywhere and select New-> Integer. Name it “nglayout.initialpaint.delay” and set its value to “0″. This value is the amount of time the browser waits before it acts on information it receives.
13) Limit RAM usage. If Firefox takes up too much memory on your computer, you can limit the amount of RAM it is allowed to us. Again, go to about:config, filter “browser.cache” and select “browser.cache.disk.capacity”. It’s set to 50000, but you can lower it, depending on how much memory you have. Try 15000 if you have between 512MB and 1GB ram.
14) Reduce RAM usage further for when Firefox is minimized. This setting will move Firefox to your hard drive when you minimize it, taking up much less memory. And there is no noticeable difference in speed when you restore Firefox, so it’s definitely worth a go. Again, go to about:config, right-click anywhere and select New-> Boolean. Name it “config.trim_on_minimize” and set it to TRUE. You have to restart Firefox for these settings to take effect.
15) Move or remove the close tab button. Do you accidentally click on the close button of Firefox’s tabs? You can move them or remove them, again through about:config. Edit the preference for “browser.tabs.closeButtons”. Here are the meanings of each value:
* 0: Display a close button on the active tab only* 1:(Default) Display close buttons on all tabs* 2:Don’t display any close buttons* 3:Display a single close button at the end of the tab bar (Firefox 1.x behavior)

how to make strong passwords.....................

When you create an account on a website, you may have the “password dilemma” for a second. The dilemma is whether you should provide a weak password that is easy to remember or a strong password that is hard to remember. Following are the rules and guidelines that may help you in overcoming the password dilemma and help you in creating a strong password that are secure. These are the things that I’ve used over years based on my own interest in the area of keeping the password safe and secure.
I. Two essential password rules:
Following two rules are bare minimal that you should follow while creating a password.
Rule 1 - Password Length: Stick with passwords that are at least 8 characters in length. The more character in the passwords is better, as the time taken to crack the password by an attacker will be longer. 10 characters or longer are better.
Rule 2 - Password Complexity: Should contain at least one character from each of the following group. At least 4 characters in your passwords should be each one of the following.
Lower case alphabets
Upper case alphabets
Numbers
Special Characters
I call the above two rules combined as “8 4 Rule” (Eight Four Rule):
8 = 8 characters minimum length
4 = 1 lower case + 1 upper case + 1 number + 1 special character.
Just following the “8 4 Rule” will be a huge improvement and instantly make your password much stronger than before for most of you who don’t follow any guidelines or rules while creating a passwords. If your banking and any financially sensitive website passwords doesn’t follow the “8 4 Rule”, I strongly suggest that you stop everything now and change those passwords immediately to follow the “8 4 Rule”.
II. Guidelines for creating strong passwords:
Follow “8 4 Rule”. Like I mentioned above this is the foundation of creating a strong password.
Unique Characters. Should contain at least 5 unique characters. You already have 4 different character if you’ve followed “8 4 Rule”.
Use Password Manager. Strong passwords are hard to remember. So, as part of creating a strong password you need a reliable and trustworthy way of remembering the strong password. Using password management tool to store passwords should really become a habit. Anytime you create a password, note it down on a password manager tool, that will encrypt the password and store it safe for you. I recommend Password Dragon (Shameless plug. I’m the developer of this software), a free, easy and secure password manager that works on Windows, Linux and Mac. This can also be launched from the USB drive. There are lot of free password manager tools available, choose the one that best suites your taste and use it.
Use Passphrase. If you don’t want to use password management tool, Use Passphrase to easily remember the passwords. You can use initials of a song or a phrase that are very familiar to you. for e.g. “Passwords are like underwears, change yours often!” phrase can be converted to a strong password “Prlu,Curs0!”
III. Guidelines for avoiding weak passwords.
Avoid the following in your passwords. Even part of your passwords should not be anything in the following items.
Password same as username or part of the username
Name of family members, friends or pets.
Personal information about yourself or family members. This includes the generic information that can be obtained about you very easily, such as birth date, phone number, vehicle license plate number, street name, apartment/house number etc.
Sequences. i.e consecutive alphabets, numbers or keys on the keyboard. for e.g. abcde, 12345, qwert.
Dictionary words. Dictionary words with number or character in front or back
Real word from any language
Word found in dictionary with number substitution for word look alike. for e.g. Replacing the letter O with number 0. i.e passw0rd.
Any of the above in reverse sequence
Any of the above with a number in front or back.
Empty password
IV. Common sense about passwords:
All the following points are nothing new and very much common sense. But most of the time, we tend to ignore these items.
Create unique password every time. When you are changing a password for an existing account, it should not be the same as the previous password. Also, do not use incremental passwords while changing it. i.e password1, password2 etc.
Change your passwords for all your accounts once every 6 months. Since passwords have a fixed length, a brute-force attack to guess the password will always succeed if enough time and processing power was available to the attacker. So, it is always recommended to change the passwords often. Schedule an recurring appointment on your calendar to change your passwords once every 6 months.
Never write down your passwords. Creating a very strong password and writing it down on a paper is as bad as creating an easy to remember weak password and not writing it down anywhere. There are several interesting surrey’s done on this subject, where it was found that several people write down the password and keep it somewhere next to the computer. Some of them think keeping the post-it note below the mouse pad is secure enough. You should never write down the password on a paper. If you want to carry your password along with you all the times, use a password manager tool that runs from USB stick and take that with you all the times.
Don’t share with anyone. Anyone includes your friends and family. Probably you might have heard the phrase “Passwords are like underwear, don’t share with anybody”. We teach our kids several things in life. Teaching them about online safety and not sharing the password with anybody should be one of them.
Never keep the same password for two different sites. It is very tempting to create one set of passwords for all your emails, another password for all the banking sites, another password for all the social networking sites etc. Avoid this temptation and keep unique passwords for all your accounts.
Don’t type your password when someone is looking over your shoulder. This is especially very important if you type slowly and search for the letters in the keyboard and type with one finger, as it is very easy for someone looking over your shoulder to figure out the password.
Never send your password to anybody in an email. If you follow #3 mentioned above, this should not be an option. But the reason I’m specifically saying about this is because several hackers send emails as a support person and asking for your user name and password through email. Legitimate website or organization will never ask you for your user name and password either via email or over telephone.
Change password immediately when they are compromised. Even if you have the slightest doubt that someone might have stolen your password, change it immediately. Don’t even waste a minute.
Don’t use the “Remember password” option on the browser without setting the Master Password. Don’t use this feature of the browser to store your username and passwords without enabling the “Master Password” option. If you don’t set master password on the firefox browser, anybody who uses your firefox browser can see all the passwords that are stored in the firefox browser in plain text. Also, be very careful with this option and say ‘Not Now’ in the remember password pop-up, when you are using a system that doesn’t belong to you.
Don’t type your password on a computer that does not belong to you. If possible, don’t use someone else computer that you don’t trust to login to any website, especially to very sensitive website such as banking. It is a very common practice for hackers to use key loggers that will log all the key strokes on a system, which will capture everything you type including the passwords
