Thanks Fred. It was AVAST. That wouldn't have occured to me in a month of Sundays as I don't normally use it. I installed it for a one off search a while ago and didn't shut it down. Thanks again.

Start Firefox in Safe Mode {web link}

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

Is this also the case with Copy/Paste ?

Isn't the clipboard not working at all ?

Thanks for the replies.

copy/paste also not working ( mechanism exactly the same)

Tried using the Treminal command :- sudo update_dyld_shated_cache in terminal - didn't work.

Starting in safe mode also had no effect.

Start your Computer in safe mode with network support. Then start Firefox. Try Secure websites. Is the problem still there?

I was quite astonished to find that after booting in 'Safe Mode' I could Copy& Paste but of course I don't want to stay in that mode. Any cure?

Computer safe mode? That means one of the other programs on your system is causing the issue.

As a test, disable your protection programs.

Hello! I'm new is this forum. I have another problem with Copy & Paste. Sometimes i can't use Copy & Paste with my mouse. See image. I have to restart my iMac to solve the problem. I've tried almost everything. In Safari no problem. Things i've tried:

  • Reinstalled Firefox and removed profile
  • Started Firefox without add-ons
  • Reinstalled MacOS
  • Bought another mouse
  • iMac started in safe mode
  • All protection off

Maybe the cause is one of these extensions. Details:

  • Firefox for iMac. Latest version: 73.0.1 (64-bits)
  • MacOS Catalina10.15.3
  • Sophos Home Premium 2.2.7
  • Logitech MX Master 3
Maybe somebody knows the answer. Thanks in advance!
