Optimoz Tweaks no longer appears to work with Firefox 3.6 despite me making my usual alterations.
At present I do not have the time nor ability to attempt to fix this, so I do apologise. Download it anyway and give it a go but I’ve had no success myself.
I have now updated Optimoz Tweaks 0.4 to run on Firefox 3.6.
You can get it here. Enjoy.
There’s plenty of information on the history of me unofficially ‘maintaining’ this useful extension, it can be found on the Mozillazine Forums here.
