firefox: latest version 2.0.0.14 (but this also happened in previous versions)
custom buttons 2: latest version
os: windows xp sp3 (though i know it's the same thing in sp2)
symptoms/example:
i type any text in google and hit search, then i open a new tab and start typing the same text, firefox automatically gives you the suggestion of the word (or words) i typed before, but if i close firefox completely and open it again the suggestions are gone, one funny aspect is that not all suggestions are gone, somehow some of them are still there, before i didn't knew the logic of those but now i know the working saved forms were all done before installing custom buttons
i only have one custom button, one that mimics the GO button that i found here and i made some changes to my likings...
this is not something that just happened now, this problem is very old, most probably since i've start using custom buttons, only now i decided to solve it
