Review for MinimizeToTray by EroMraB
Rated 5 out of 5 stars
I just override the compatibility checking with the "MR Tech Toolkit" so that I can install the out-of-date version. No offense to kn1106, but I'm not installing an add-on from some random page. Never know what it could have in it!
This add-on should be default for Firefox. I dunno how I'd live without it :-)
