In my IT Dojo video, Firefox about:config hacks that can speed up and customize your browser, I demonstrate several Firefox about:config hacks that can potentially speed up your browsing experience, force Firefox to spellcheck all text boxes (not just those with two or more lines), and eliminate the annoying countdown when installing add-ons.

Unfortunately if you like to play around with Firefox betas, you’ll find that most of your add-ons usually don’t work with the prerelease software. However, there’s a trick to make add-ons work in the beta version. In this episode of CNET’s show Hacks, Executive Editor Tom Merritt shows you another about:config hack that lets your old add-ons work with Firefox beta releases.
