If you do not keep changes after a restart then see:

I solved my problem by re-installing 16. I don't know what was changed in 17 but I won't install it again until it's fixed or any other update.

tried FF 17.0.1 and Abine PrivacySuite is still being disabled by FF... still using FF 16.0.2

I'm still having the same problems, too. Will stick with 16 until problem solved.

Once you reinstall will work with FF17....you just have, one you restart FF, to go to TOOL. Privacy Suite logo should be on bottom and then click...'Show Toolbar Icon'

It was there all the time! Just not showing up on the toolbar, but hidden in tools instead of in Toolbar like it was.

Cheers.

Unfortunately, it wasn't 'there all the time'. FF17.0.1 still disables Abine Privacy Suite 0.749 and when Abine is disabled it does not show in the Tools menu or the toolbar. I'm still using FF16.0.2 because it does not disable Abine (and I tire of re-installing Abine and FF17 just to see if they might work together again).

Abine PrivacySuite 0.750 works with FF 17.0.1. Unfortunately, FF 17.0.1 has disabled Java. A possible fix is here: https://support.mozilla.org/en-US/questions/942594 although this has not worked for me... More lost time..
