Firefox usually works great, but starting last night it has been messing with my computer like crazy. I have a wireless mouse, and a Wacom tablet/pen. Everything has worked fine, but starting last night I had to Restore Down the Firefox window with the Wacom because nothing happens when I try with my mouse. Once the window is has been Restored Down, my mouse freezes, and I have to go into Task Manager with the keyboard to get it to work again. I then have to use my Wacom as a mouse if I want to click something in the taskbar, the mouse for the start menu and any non-Firefox programs, and Firefox will just not work at all. I can't switch/open new tabs, I can't click the address bar, or the search bar, I can't go to a different site, or anything. I have to open Task Manager to close out Firefox, then everything works fine. I reopen Firefox and it works fine except not being able to use the Minimize, Rrestore down, and Close buttons without using my Wacom, and then when I do, the cycle repeats. I have tried unplugging things, putting in new batteries, nothing has worked and I don't know what could be causing this issue when Firefox has worked great for me all these years. I'm currently running a virus scan on my PC, but I don't see why it would ONLY be effecting Firefox.
