I love the newly installed version of Firefox on my Windows 10 Computer but, sorry, it's often hanging in the middle of browsing and not responding!

Please help restore and resolve.

Thank you.

Start Firefox using Troubleshoot(Safe) Mode {web link}

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