Firefox 3.6 complete reset after uninstalling Firefox 4 Beta 9!!!

more options

Now what the heck is this?!?! I wanted to try out ff4 beta 9, installed it to a separate folder, found out it doesn't support some of the extensions I need, deinstalled it, and voila - my ff 3.6 just completely reset EVERYTHING!!! I'm a web designer and I have heavily customized my ff, and had LOADS of passwords saved, like Joomla extensions registrations. And here comes the new ff4 and f***s it all up?!

The first time I installed ff4 it was beta7, and after uninstalling it my ff3.6 had disabled the extensions not compatible with ff4. I can live with that, and I SHOULD HAVE BACKED UP, but come on!!! You should put a great big red warning when downloading ff4 - THIS CAN MESS UP YOUR OLDER VERSION OF FF!!!! BACKUP EVERYTHING!!!!

If you want to use a Firefox 4 beta version (beta 10 has just been released) the you should create a new profile exclusively for the 4.0 beta version and create a desktop shortcut with -P "profile" appended to the target to launch that profile.


Delete the files extensions.* (extensions.rdf, extensions.cache, extensions.ini, extensions.sqlite) and compatibility.ini in the Firefox profile folder to reset the extensions registry. New files will be created when required.
See "Corrupt extension files": http://kb.mozillazine.org/Unable_to_install_themes_or_extensions

If you see disabled, not compatible, extensions in "Tools > Add-ons > Extensions" then click the "Find Updates" button (in Firefox 4: right-click the extension -> "Find Updates") to do a compatibility check.

When you uninstalled it did you select the option to "Remove my Firefox personal data and customizations", that will remove all of your Firefox user data. That option is not selected by default, so a normal uninstall would only remove the application and not touch the user data.

No, I did not select that option. My post is not exactly a question, so I'm not waiting for an answer. What I'm trying to say is that developers know what a BETA means, and one of the first presumptions is that ff users would install it alongside ff 3.6 for comparison, and they should have made sure it won't mess with our settings.

But nope. Got me thinking about Chrome and Iron, but the addons are what keep ff on top. For now.

@cor-el Checked out your links, and it's very helpful to everyone who wants to try, I'm just sticking to 3.6 until stable is released. I'm marking this solved, there's nothing to add to what you've posted.

Cheers

I want to get 3.6 back !! 4.0 SUCKS !!!!!! It takes forever for everything to load, plus some ad-on's don't work. Where can I find 3.6 ?? It only shows 4.0 in "add/Remove.
