I cannot customize anything but the Bookmark Bar, and none of those customizations make any sense. I cannot add a Home icon or New Tab icon in front of the address box--I used these all the time and do not want to do without them. I was not able to add my favorite search engine by following the directions on the Help page. Is there a way to downgrade back to my last version of Firefox with all my settings intact? The rest is /rant. I know I have the flu and am a bit cranky, but putting a button there that says 'Refresh Firefox' (when you should have said "Install new Firefox with weird settings without existing features") was not very clear. I thought it was just a check to see if all the parts of Firefox were present and uncorrupted. That's what refresh means. Also, being greeted by "Firefox Certificate Store Hotfix nnnnnnnnnn.n (disabled)" without any means of enabling it was problematic at best. Kind of like having found out a gorilla packed your parachute. After considerable time searching it seems that it doesn't work with 36? Why didn't it just say that? Security features mysteriously disabled is suspicious, as in something malware would do. You guys and gals are great, but give a guy warning. Thanks for Firefox.
