One of the most interesting additions in Firefox 3.6 is a new support page called about:support which can help the Firefox user and technicians in troubleshooting web browser problems. The support page lists important application, extension and modified configuration settings that can be used to troubleshoot problems.
All Firefox 3.6 users can enter about:support in the address bar of the Internet browser to display the support page.
Application Basics lists the name and version of the browser. The section also links to the Firefox profile as well as the about:config and about:buildconfig pages. The link to the Firefox profile folder can be very handy as it is usually faster to access that way than to use a file browser.
All installed extensions are listed in the extensions section of the support page. Extensions are listed with their name, version, status and ID.
Modified Preferences is the final section which is probably the most important one for troubleshooting the web browser. It lists all configuration parameters (in about:config) that have been modified by the user. These are often the cause for problems that are experienced in the browser.
The about:support page can be helpful in various situations but most importantly for troubleshooting the browser.

Firefox is already running, but is not responding
Nice! (I wish ABOUT pages would open in a new TAB!!).
But under “Modified Preferences” why do I have a large amount of printer settings from printers that are no longer installed on my system? And I cannot find any traces of these printers in the hardware list (even showing hidden devices) or in the registry.
So where is Firefox getting these from? Maybe left over in the profile?
How do I clean old garbage out of the Firefox profile w/o having to rebuild it from the beginning?
Jojo Firefox does not seem to clear data from uninstalled devices or extensions automatically. The only way that I know of is to either use a default configuration again or clear the items manually.
Have a strange one. There is an online game site called pogo. Have played on it off and on for months using FF3.0. All of a sudden yesterday, I get error messages that javascript is no longer associated with this pgm. Also, one of the mouseover links here did the same thing. I upgraded to 3.6 and no change. I have latesat java so am lost as to where to go. I tried speed test – speakeasy and it worked even tho I got the error message.
Error: Permission denied for to call method UnnamedClass.toString on .

On this page, the link “printer” gets an error message while the link word java works in kontera as does the bottom word link javascript
You mean on the page here at ghacks? Can you reload the page and clear the cache before to see if it was a simple transfer error? Thanks
to clear data from uninstalled devices or extensions you can edt directly “prefs.js” file , located “C:Documents and Settings******Application DataMozillaFirefoxProfiles”name of active profile”
Firefox 3.5.9′s updates won’t play some videos on Youtube. Didn’t have this problem before the update. Now after the update I’m having problems. Nothing in my antivirus software is blocking anything from Youtube. I go to do a page source and it tells me there’s a Java Script error. Whenever I turn off my adblock, the videos that wouldn’t play will play and I never had to do this before. What’s the deal with the new updates messing with some of my Youtube videos and how can it be fixed???
