I have been using Firefox as my default browser for years. Lately it has
been acting up. I don't know if anyone else is having similar problems.
Maybe it is because I have had dozens of updates and updates add-ons.
For the last few weeks it started freezing up if unattended for extended
periods. The it started freezing up more frequently. By today it was
just crapping out completely every time I tried to do something.

So... I uninstalled it.. after importing the bookmarks to IE. Then I
rebooted and used IE to find and download and install Firefox. Once
installed I tried it out. It works great. It even has all my old book marks.
