newest update kills FF... tried everything downloaded old version and it works fine... your ball
Firefox 49.0.1 update seems to load, shows brief busy icon .. shows loaded in files, shows as running in task mgr. Removing and reloading does nothing even with shutdown between... safe mode, administrator run... nothing. Reloaded old 48 ran without a pause.

Let's start with this;
Some problems occur when your Internet security program was set to trust the previous version of Firefox, but no longer recognizes your updated version as trusted. Now how to fix the problem: To allow Firefox to connect to the Internet again;
- Make sure your Internet security software is up-to-date (i.e. you are running the latest version).
- Remove Firefox from your program's list of trusted or recognized programs. For detailed instructions, see
Configure firewalls so that Firefox can access the Internet. {web link}
Start Firefox in Safe Mode {web Link} by holding down the <Shift>
(Mac=Options) key, and then starting Firefox.
A small dialog should appear. Click Start In Safe Mode (not Refresh).
Is the problem still there?
