List, After I think the last or next to last update to firefox, I started seeing some problems, wherein I no longer have a "back" function on any pages or tabs. Also, I get some kind of strange message.... "Assertion Failed ASSERT:***Search:_installLocation: engine has no file! Stack Trace: 0 ENSURE_WARN(false,_installLocation: engine has no file!.2147500037) 1:()2:()3:()4:90:epsGetAttr([objectObject],hidden)5:906:907:currentEngine() 8:get_currentEngine()9:updateDisplay() 10:init() 11:([object XULElement],0) I realize this is not the proper place for FF related problems, but thought I'd ask if someone else has seen something like this happen. Prior to the last 2 updates, FF appeared to be working properly, and all the forward/back buttons worked. Assistance would be mighty helpful.. Thanks Sa,
