Firefox Not Responding

Running Windows 10, latest updates installed. Latest updates of Firefox installed.

Whenever I switch tabs or switch between programs, I am constantly getting 'Mozilla Firefox- Not Responding' in a blue bar at the top of the browser along with a white page (where previously I'd been reading a website) and a gear cog in grey in the middle. I sometimes have to wait up to 5 minutes for the browser to respond again.

I also have the problem that Firefox locks up if I open the Skype app, so I can either use Skype or use Firefox, not both together.

What's your computer system and Firefox version?

It sounds like the computers CPU is being overworked.

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?

Hi Fred, The computer is actually at my parents house so I don't have access to it until the weekend. The computer is a fairly generic bought from an independent supplier, so doesn't have a brand name (like Asus, Acer etc) It was originally purchased as a Windows 8.1 machine and upgraded to Windows 10. I will get as much info as I can and start in safe mode as you suggest when I am there at the weekend, sorry that's not much assistance to help you solve the problem. Thanks for your help so far!
