firefox is being updated by another instance
For a few days I have been unable to check if my firefox browser is up to date.
I keep getting the message " firefox is being updated by another instance "
I have uninstalled firefox browser and reinstalled it but the problem persists.
What does the message mean and what is the significance of the message ?
How do I resolve this issue ? and why has it happened ? I don't want to stop using firefox as my chosen browser
