Firefox no longer works after upgrading to macOS Sequoia

I used FF all day on Sequoia

The headline should probably say FF with special firewall rules most people never use

After the upgrade a default firewall rule was added to block all traffic from Firefox. Running /usr/libexec/ApplicationFirewall/socketfilterfw --add /Applications/Firefox.app adds a rule to allow it and the app works as normal.

Doesn't explain why it sometimes works sometimes doesn't though?

Rule:

If your OS is macOS, it's the application's fault.

If your OS is Linux, it's your OS's fault.

Is this sarcasm or a reference to something I'm missing?

MacOS seems to have a lot of apologists. Linux seems to have a lot of haters. If you haven't observed this to be the case, then it probably doesn't make sense. But it does seem to line up with what I've seen.

{MacOS,Linux} seems to have a lot of {apologists,haters}.

There, fixed that (with a bashism) for you.

Nice. Thanks.

Conventional wisdom

I've got this after updating to Sequoia today as well, weird behaviour as Firefox network traffic will randomly stop working for a few minutes, then work again.
