I do indeed have Advanced System Care with Surfing Protection, but I tried turning it off and then reinstalling Firefox, but no change-same problem.ДЄgain and again I see the advice to go to Troubleshooting Information and click on the Refresh Firefox button.

I could flounder around and experiment, but I really rather have someone who knows what he's doing tell me. I made a backup of my original profile folder. Now my question is how do I restore all my bookmarks, add ons, etc. But someone else might benefit from this bit of info. It's all incomprehensible to me, so it doesn't really help.

#Onedrive qt platform plugin windows how to#

When I ran the javascript diagnostic I discussed above, I got an error message which led me to discussions of 'stack overflow', and every discussion I see of how to fix this Qt platform problem also mentions 'stack overflow' and javascript. I still suspect the error message I get at start up about OneDrive not finding the Qt platform plugin 'windows' must be related somehow. I turned it off and on again, and maybe that reset something. I don't have Norton 360, but I do have Norton Security which has a section called Firewall Program Control. I already tried turning off surfing protection in Advanced System Care, and that made no different. At least I can open it successfully without getting a message about not being able to open because the profile folder can't be found.

For reasons that are a complete mystery to me, Firefox, after yet another reinstall, seems to be working.
