Rated 5 out of 5 stars

Epic addon, VERY useful, please consider update it for 3.5/3.6

This review is for a previous version of the add-on (1.1.3). 

Firefox 3.5 update has been uploaded

I have uploaded a new version of Classic Compact Options that is compatible with Firefox 3.5. It is should be made public very shortly once it has been reviewed by an AMO reviewer.
