PasswordMaker 0.8.1 is not compatible with "Download Manager Tweak" 0.6.6.
If I enable "Download Manager Tweak", PasswordMaker can't work.

When I upgraded PM from 0.7.3 to 0.8.1, all input boxes in the PM basic options window were blank and the generated password of PM was empty.
I tried to disable other extensions one by one to make sure which conflicted PM. Then I got Download Manager Tweak.
However, after I reinstalled firefox and all extensions, every thing is fine. Now I'm still confused and don't know what's wrong.
