Firefox Tricks

FirefoxAs every new browser hits the web , not only it’s features gets exposed but also it’s major bugs , tweaks got exposed.It doesn’t matter whether it’s IE9/FF4/Opera11, experts finds out what tweaks/tricks and bugs could be identified in a released version .Here we discuss some Firefox Tweaks( might be knowing) ,the way you can customize the features as well as hidden functionality in our favorite browser.From the basics lets start with the hidden or unknown “about:” pages

Firefox has got  a dozen of hidden pages that features on it’s configuration , browsing functionality, caching etc . To view all these hidden pages just open a new tab ->Type or paste  in the URL bar ->  about:about


No, the list is not over yet , For a complete Browser’s list of  ” about” pages visit Wikipedia List .

Swap out Memory

On Windows operating systems, when a program is minimized and left for a period of time, Windows will swap memory the program is using from RAM onto the hard disk in anticipation that other programs might need RAM. So to reduce  RAM usage  when Firefox  tab is minimized ,it could be  set in ” about:config” page . Just type in URL bar-> about:config -> now type in filter section ->”config.trim_on_minimize”.If this entry is not create a new  key by right click->new->Boolean .Assign name “config.trim_on_minimize” and set value to true.

Another way to Limit RAM is by 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.

Blocking Auto Refresh

Web pages (and web servers) can ask a browser to automatically refresh a page after a given timeout by including the HTML element <meta http-equiv=”refresh”> or by sending a Refresh: HTTP header. This can be helpful (as in the case of a webpage whose content is updated constantly) but it also can be irritating.So to get rid of Auto refresh goto about:config -> now type in filter section ->accessibility.blockautorefresh. set it value to “true” for displaying a browser message indicating the refresh and allow the user to follow it manually.

Open Firefox inside Firefox

Just type in URL bar ->chrome://browser/content/browser.xul

Session Restore

There are several ways to achieve this .One simple way is to goto->Tools->Options->General->Startup->When Firefox Starts->Show my last tab and page.Another way is to set your Homepage to  “about:sessionrestore”.Another is by Open about:config in a tab. Browse/filter for ‘browser.sessionstore.resume_session_once’ and change it to true.

Lots of other tweaks are there for Firefox .What to do is just visit here-> About:Config Entries. Look up and study the features each entry has got ,then you can tweak Firefox according to your needs, and  about all Firefox is an open-source browser.
