After updating to 9.0.1 my theme/persona (MS Office by devatrox) and one of my addons (Google Redesigned) are being randomly troublesome - but the issue seems to be Firefox as it is happening with more than one. When I start Firefox they have about a 50/50 chance of both being enabled or disabled. Once the Add-ons Manager said Google Redesigned had an update and told me to restart. I did and it stayed active when I restarted, but then disabled the next time and will not let me enable it again. The support for the addon says it's Firefox's problem: http://www.globexdesigns.com/admin#!bugtracker/bug/230-firefox-9-disables-google-redesigned-0-9 My theme is doing similarly. Most every time I start Firefox it is disabled, yet I can re-enable it in the Add-ons Manager and it works fine. Having to manually re-enable the theme is getting really tiresome, and using Google Reader/Gmail is pretty impossible without the redesign addon. Please help.
