Aris You May want to start Support Thread Topic for CSTB v1.0.7pre testers Rated 5 out of 5 stars

I recommend starting one here:

http://forums.mozillazine.org/viewforum.php?f=48

Note: The reason I suggest this is that I have quite extensive bug report for CSTB v1.0.7pre2.(Using Large Icon Mode setting and 2 add-on Incompatibles that break CSTB v1.0.7pre2 on Nightly Fx14.0a1).

If you do you may want to link it to CSTB AMO site page as the Support site.

This review is for a previous version of the add-on (1.0.6.1-signed).  This user has other reviews of this add-on.

Here is the link to the new support thread: http://forums.mozillazine.org/viewtopic.php?t=2447747

Keep in mind FF14.0a1 toolbar buttons support in CSTBB is experimental because it isn't final in FF nightlys (yet?). They could change a lot of things that may break this settings even more.

In fact I see some add-on toolbar button incompatibilities too even without CSTBB installed or enabled.
There is a part in the new nightly css code where they set some paddings that affect all non-default toolbar buttons. I believe they could change this later or force ext. devs to change their add-ons code, who konws?
