Quoting the previous poster who detected (and provided the solution to) a visual bug, I also think this add-on is great but unfortunately it seems that passwdmaker.css causes a couple of formatting problems.
In this case, the conflict is with the "
Find in tabs" add-on. The problem is that the top section of the "Find in tabs" window becomes too high. Please install both add-ons and see for yourselves, since it's much easier that trying to describe it here.
The bug seems to be caused by line 35 in passwordmaker.css: "tree {min-height: 50px;}". Commenting that line solves the visual bug. I don't know how that may affect PasswordMaker, but I haven't seen any (negative) changes after the modification.
Please look into it and try to solve it in future versions.
Thanks
