Firefox about:config command

Menu: address bar / about:config

The about:config command is a very powerful tool for the advanced Firefox user, and should not be used by beginners. It will display a long list of fields that can be used to change the default behavior of Firefox for many events, or change preferences that are not accessible through the normal preferences menu. For an extended list of what each field means, consult this about:config entries page from mozillazine.org, or this Firefox Tweak Guide page from tweakguides.com. Personally, I've used it to change its default behavior toward links popping up new windows, which I changed for the link popping up a new tab instead (see: browser. link. open_newwindow). There are direct about: commands, such as inserting about:mozilla, which generates some pseudo-religious babbling (it's kind of an easter egg), or about:cache?device=disk to see the content of your cache. If you think you made an error and want to revert back to the default value, right click on that particular field and select reset. Values that are changed from the original installation will appear in bold.
