Hello! After being away from my PC for a few days I tried to open firefox and got this error:

'Firefox is al actief, maar reageert niet. Het oude Firefox-proces moet worden afgesloten om een nieuw venster te openen' aka 'Firefox is already running but not responding. The old Firefox process must be closed to open a new window'

I deleted the application in windows settings and then redownloaded it. The problem persists. What can I do?

King regards, Anton Siemonsma

Hello!

I noticed the firefox folder was somehow 'read only', but changing it is not working. When unclicking it, pressing apply an dpressing ok when its done, it somehow still is read only. Why is this?
