So you could create a developer profile and install all programmer extensions (like Firebug, Web Developer toolbar, etc.).
But if you just want to navigate, you don't need them and loading all of them just slows down the startup time of Firefox. Just use another profile without them, with a different set of extensions.
From the extension's preferences, you can choose what to do when you launch another profile (close the one in use, don't close it, ask every time).

Unfortunately, this extension can't be found on Mozilla yet, so just download it from the home-page or use this link to download the recent one when this post was written.
Link didn't work for me :(
ReplyDeleteYou are right, it changed, there's a newer version.
ReplyDeleteI added a link to the home-page (in case it changes again).
ProfileSwitcher can be found on AddOns now and is already on version 1.4
