Recently Firefox has shown several incidents where its uddenly become 'obstructed' in some manner, with Error messages displaying that prevent my accessing Firefox and using it as it's supposed to be used. I'm not a technical person who can interpret these incidents, but when these incidents happen, out of the void, I've just tried to uninstall and then reinstall Firefox. I've somehow (seemingly) been able to ultimately reinstall Firefox after these incidents, but I'm wanting to know WHY these incidents are happening? Firefox doesn't give me any help here with this question, as far as I can see, so I'm wondering why these paralytic Error messages are happening, and what I'm supposed to do to keep Firefox functioning correctly, preventing this interference with the browser's functioning? Can anyone PLEASE HELP ME with this issue here, or even point me in the right direction? Thank you very much for any explanatory help you can provide. Merry Christmas (I hope!).
