I had PasswordMaker 3.5 with Mozilla1.7 (no Ctrl-´ and icon, too) and I moved to SeaMonkey (Mozilla1.8b2 because I want it all, and don't like the icon driven crippled preference in Firefox & Co) and tried PasswordMaker3.6 (no Ctrl-´ and icon but now I used Keyconfig to define Strg-ä , which shows up as Ctrl-' but I had to press Strg and Ä and the PasswordMaker 3.6 configuration dialog shows up - nice).
You told me, that 3.6beta3 will support Mozilla and I would like to test it (for sure with SeaMonkey but I could alternatively start Mozilla1.7 because some times the 1.8b-versions are corrupted). PasswordMaker beta should be installed after removal of previous PasswordMakers, and that is, what I want to do, but didn't know how to do this correct.
Though its bit gambling, to test PasswordMaker with SeaMonkey and really not necessary (because thanks to Keyconfig, now I could use PasswordMaker), I think that it should be part of the (future, because Mozilla support was just added, as you stated) FAQ, how to uninstall PasswordMaker with Mozilla, too.
