My PC is running very slowly On logging out which takes a very long time I get a message: XUL runner Error: Platform version 126 is not compatible with miniVersion 125.03

I cannot find GoogleGoogle Play on my PC and do not use it so I can't delete and re install

Hi petaodonovan,

This is a known issue caused by a corrupted installation after a failed update. The workaround is to uninstall and then re-install Firefox to fix this issue while our team is working on a more permanent fix. You don't need Google Play on PC and you shouldn't lose any data if you download the full installer from our official source.

So sorry for taking a long time to get back here with an actual resolution.
