Well after posting this i decided to look into the add ons and that firefox accelerator seemed fishy to me so i disabled it by only using right clicks because when left clicked it closed the window and all seems to be better, as far as the downloading like IE and double loading.... although i still cannot click on the add ons screen...so i feel there is still an issue that might happen again when i restart my computer?.....

I was having the exact same issue, firefox was acting like IE.

Ctrl F brought up the IE find dialogue, right click did not have "Open link in new tab", and so on.

I uninstalled "firefox accelerator" add-on and the problem was resolved.

Oddly, when Firefox restarted and attempted to reload my windows, each window address had the prefix : chrome://ietab2/content/reloaded.html?url= but I don't have the chrome browser installed.

Seems like Firefox Accelerator is some kind of malware!

"Oddly, when Firefox restarted and attempted to reload my windows, each window address had the prefix : chrome://ietab2/content/reloaded.html?url= but I don't have the chrome browser installed. "

In Firefox-speak, the word "chrome" refers to the browser interface around the web page (e.g., menus, toolbars, status bar).

ietab2 sounds as though it could well be related to the IE Tab add-on, which lets you selectively embed IE into Firefox tabs.
