Getting Greasemonkey working with Firefox 3 RC1

WARNING/Disclaimer: This is an approach for the brave or those who are desperate to get their Greasemonkey extensions working again.

It’s by no means scientific, but I use Greasemonkey a lot (and a couple of other extensions too), and really wanted it back!

What I have: Firefox 3.0 RC1, Greasemonkey 0.7.20080121.0

1. Go get yourself the Nightly Tester tools (2.02) here
2. Make a note of all the extensions/add-ons currently enabled – consider this your safe list!
3. Install and enable it
4. It will ask if you want to override the extensions and enable them – say yes.  Note: at the next step Firefox will almost certainly fail to load!
5. Let Firefox restart – it may well fail!
6. open a command window and cd into the Firefox install location.
7. Run ‘firefox -safe-mode’ to restart in safe mode
8. Click the disable all extensions and continue
9. Once restarted, go into Tools, Add-ons and enable all the things in your safe list.
10. Enable Grease Monkey
11. Restart firefox
12. Done!

Well…hopefully.  If not restart in safe-mode again and disable greasmonkey and check all else is still ok.

If you have other extensions you want to get working, you can repeat this process.  I did manage to get a couple of others working, but not Google Gears
