Doesn't work in Seamonkey 2.5 Rated 1 out of 5 stars
It is installed properly and it has it's options in Add-ons manager, but it does nothing. Menu is not changed. Too bad because I just to use this great tool for quite time in older versions of Seamonkey (Compact menu)
Work correctly in SM2.5b4
Please try clean install or disable other add-ons.
