What OS? I almost never close out of Firefox on my Macs at home and I’ve never seen that message there. FF on Windows seems to be the same. It’s been ages though since I’ve left FF open for months on end on Linux though.
On Linux, disabling Firefox updates in Firefox itself will not fix this issue, because Firefox’s own updater doesn’t actually have this bug! You get this warning when the Linux package manager has already replaced the files underneath the running program.
You say it’s windows, but I think you said it’s a work machine so maybe they’re updating firefox from under you?
Restart Firefox to let it finish updating. I don’t think I’ve ever seen a screen that says you HAVE to restart right now at this very moment.
When it happens, it doesn’t let me do anything other than stay on the already loaded webpage without restarting.
Open a new tab > “Restart to continue…”
Click a link > “Restart to continue…”
Type a URL > “Restart to continue…”
and etc

It happens on Linux – after your package manager has updated Firefox. Which typically means that you told it to. So it’s not really a surprise.
