Hello all, I am using Windows 10 64-bit. I have Firefox version 66.0.1 Everytime I open Firefox, after about 20-30 seconds, the application hangs. I get the "Not Responding" message in the menu bar, and the cursor pointer changes to a spinning blue circle. The application hangs usually for up to 2 mins before returning to normal. It then always works perfectly for the rest of the browsing session. I've tried closing in Task Manager and relaunching, but the same thing happens. Has anyone solved this issue? Thanks
