Check Your Plugins infinitely running when selected. Doesn't work
From the Add-Ons page, I select "Check to see if your pluggins are up to date". The rotating circle runs and runs and runs and never displays the resultant screen. I can also hit this error when I select "Update Now" from a plug-in.
Running Mozilla Firefox 49.02 on Win XP. (Which has been working up to now)

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?
Use this link to check that your plugins are up-to-date. If any are listed as unknown or research, do not worry about them.
