Windows 7 - Firefox 3.7a5pre & TabMixPlus-beta, BIG PROBLEMS !

hi !

a warning: do NOT install the "nightly build" of Firefox 3.7a5pre from today (2010-04-29)
if you are using TabMixPlus-beta !

after updating (almost) nothing worked, only options & exit....
i had to go back to older builds to get FF working again,
i´m using the version from 2010-04-17 now,
first i tried 2010-04-28, then 2010-04-24, but FF still didn´t work as it did before upgrading.

nb.
April 17, April 28, April 24, for those who don´t know how to write dates properly...

hi !

update: today i installed Opera 10.53 & while testing it on peacekeeper i closed FF 3.7a5.
after i had tested Opera, which was VERY fast btw. (1002 p !) i started FF 3.7a5 again, and the problem was back.

i reinstalled TMP, but it didn´t help, but after reinstalling FF from 2010-04-17 everything was back to normal.
i then tried todays (2010-04-30) nighly build, which gave the same problem again, the problem seems to be that if you close FF, then TMP´s session manager freaks out.
