Among various Firefox features there is an important feature also which is its ability to save the passwords you enter to log on to different web sites. For ex. whenever you login at your yahoomail, there’s a window popup in which you usually click on ‘Remember’ tab so that you don’t have to type them every time you want to login.

But infact those passwords are easily accessible to anyone with access to your computer. If you don’t beleive that then follow the steps given below:

a) Navigate to Tools>>Options.

b) Click on security tab and then on show password tab.

c) Now you can see all your saved passwords in this Remember passwords window.
This is a flaw in firefox that can be very dangerous as anyone using your computer can find all your passwords within 10 seconds.

To prevent yourself from this, you have to do a little but prominent thing i.e.
Tick the ‘Set a master password’ button above the show password tab on the page and set a password there…..
Your saved passwords are safe now !!!

One of the most active areas during performing work in Firefox is using ‘tabs’. So, here is a tweak for Firefox tab scrolling:
1. Type about:config in the browser and press enter.
2. Find the key browser.tabs.tabMinWidth on the page.
3. To allow smaller tab widths before scrolling, you can set the number to a smaller number.
4. To disable the feature, set its value to ‘0′(zero).
5. Now close the page and start a new session of firefox.

Here’s something for broadband people that will really speed Firefox up for them. I have just tested this tweak and it does make the pages start loading significantly faster than ever before.

1. Type about:config into the address bar and hit ‘Enter’.

2. Find “network.http.pipelining” on the page and set it to “true”.

3. Find “network.http.proxy.pipelining” and do the same to it.

4. Find “network.http.pipelining.maxrequests” and set it’s value in between 15 to 20.

5. Now right-click anywhere and navigate to New-> Integer, name it “nglayout.initialpaint.delay” and set its value to “0″.

6. Lastly Restart Firefox.

Now if you are using a broadband connection you’ll definitely load pages faster now. You should now have a quicker, alot faster web browser that loads pages without a delay. And if you’re reading this but not doing it, then you are missing out on a serious speed increase.

A built-in spell checker in Firefox enables users to quickly check the spelling of words misspelled by you in any text boxes (in which you can enter text) and also automatically correct them. But this is not the same case in the search box. Infact this doesn’t seems to work in search boxes like google search.

To make it work in search boxes as well you have to do:

1. Open Firefox.

2. Now type ‘about:config‘ in the address bar and then press ‘Enter’.

3. Doubleclick on ‘layout.spellcheckDefault‘.

4. And change it’s value to ‘2‘ and you are finished.

1. Open Firefox, type about:config in address bar and then press Enter.
2. Right Click in the page and select New>>Integer.
3. Type a new integer “browser.cache.memory.capacity” in that box.
4. Set it’s value to 5000( RAM 128-512MB) or 15000( RAM 512-1GB).
5. Now right click on the page and navigate to New>>Boolean.
6. In the box that pops up enter “config.trim_on_minimize”.
7. Now select True and press ‘Enter’ key.
8. Restart Firefox.

Blinking elements can be a problem for persons using screen-readers, screen magnification applications or users with cognitive impairments. Sometimes the blinking elements are just annoying to see. You can disable the blinking elements by following the given steps:

1. Open up Firefox and then type about:config into the Address bar and Press ‘Enter’.

2. Type “browser.blink_allowed” into the filter bar.

3. Change “browser.blink_allowed” value to False.

4. Then close Firefox.

Firefox allows almost anyone with minimal coding experience to create plugins and addons to make Firefox much better. But this sort of thing can lead to the greatest browser worse.
Stability, performance or security flaws are some important criteria which should be kept in mind while choosing a firefox extension. Here is a list of 10 avoidable firfox extensions:

1. FasterFox: This extension can lead to an incredible waste of bandwidth. The idea behind this is that if you are reading a page, while your system is idle, Fasterfox silently starts following links and downloading the destination pages. This will result in a total waste of bandwidth.

2. NoScript: This extension generally work as a advetiser. You can whitelist the sites you think are safe, and can also blacklist those who are not safe according to you. But for the average Web surfer this extension is not recommended at all.

3. Adblock: This extension attempts to block all online advertising. This extensions are not good for online publishers.

4. PDF Download: This extension allows PDF files to open in the external PDF viewer of their choice rather than the Adobe Reader plug-in for Firefox. But the problem with this extension is that it does not work when some websites redirects you to the PDF for tracking purpose.

5. VideoDownloader: The problem is that the extension has to connect to a Web site in order to work which is again a big problem in it.

6. Greasemonkey: If you are not familiar enough with JavaScript then just skip this extension.

7. Scribefire: This extension is a browser-based tool for writing blog posts. Most blogs already have a browser-based editor, so there is no need use this extension.

8. Trackmenot: This extension runs in the background while you surf, and sends search queries to Yahoo, Google and some other seach engines which is just a waste of time and resources.

9. Tabbrowser Preferences: This extension does not reset your tab settings, which this extension let you tweak after installing it, after uninstalling this extension.

10. Tabbrowser Extension: The developers of this extension suggest not to install it. So, you should skip this extension also.
