If you use TabMixPlus, you MAY wait with FF updating.Tab Mix Plus Dev-Build 0.3.6.1.080416 WORKS.

This is what I'm getting, when trying to update:



so I'm not sure, if I should take a RISK?I don't know why they won't sign off on it through mozilla. Everyone keeps asking but they aren't answering for some reason.

The link above works, and is safe. It's what I had to use when I updated today and comes from the Tab Mix Plus forums - http://tmp.garyr.net/forum/index.phpWrong link above. Here is the dev builds thread - http://tmp.garyr.net/forum/viewtopic.php?t=7031I have build 416 installed, but FF warns me about incompatibility.
Did you install 3.0.1, and TMP works?No and yes. When I updated to 3.0.1 today TMP wouldn't install (incompatible) so I went to the forums and reinstalled the latest build and it worked fine. GOT a warning but ignored it.Wait. You didn't have TMP before 3.0.1 update?Yes I had the same build I do now with FF3.0. When I updated to FF3.1 today TMP wouldn't install. I think the NEW FF3.1 "broke" the TMP install. Not sure, all I know is I reinstalled it and it was back to normal.Oh, OK. Here is a thread discussing what happened. I don't understand half of it but I think what they are basically saying is to reinstall the dev build .I did edit install.rdf file as prescribed in your link, FF update still gave me warning about TMP, but update installed without damaging TMP.
Good, thanks.I don't know who is to blame, the developers or mozilla but I wish they would get it together. It's been long enough now.
