Getting old extensions work with Firefox 3

Filed under: — Alex Salamakha @ 8:35 AM

I’ve been complaining about Firefox being a memory hog earlier, so I decided to try new Firefox 3 beta 2. It’s been a lot less aggressive in its memory consumption and is quite stable, which is a fantastic result for a beta. On the down side, most of my add-ons stopped working. I can live without many things, but I can’t live without Yahoo del.icio.us and Web Developer add-ons.

Luckily I’ve found this neat trick to enable your old Firefox 2 extensions in new Firefox 3:

1. Navigate to about:config address
2. Right-click and select New >> Boolean
3. Name it extensions.checkCompatibility
4. Set it to false
5. Restart Firefox

All your old add-ons will try to work and most of them will. At least both Yahoo del.icio.us and Web Developer add-ons work just fine for me.

UPDATE: this no longer works for Firefox 3.6. Click here for the solution for 3.6.
