Guess it just requires some manifest/firefox hacking then. The top reviews complain just exactly about not working on ff6 and 7.

Question: Did you try the Compatibility Reporter[1] yet?

I'd wager that 95% of all addons will work without problems with version checks disabled - and I'm using the Nightlies. The only one so far that didn't work correctly since a while is Tree Style Tabs, which I assume is due to the fact that it heavily modifies the interface.

That is a great addon. But ever since yesterday, delicious addon can't do full sync for me, which left me in a no bookmarks state.

If you try it, make a backup of your FF configs, as if it doesn't work, it will also leave you without local bookmarks.

If I can't get the sync back, making it work on FF 7 will be least of my worries... (Yes, I reported it to Avos team).
