I revamped my computer with all new hardware and installed Firefox. I found that it was taking 3 tries to get the window to stay up and not crash immediately. This has been ongoing for a few months. For no reason that I can see (I have not downloaded anything new), it is now opening up hundreds of windows and does so with just one click on the icon instead of the usual two. I can start to close the windows and narrow it down to just one, sometimes. Other times it just freezes or starts to open up new windows again.
