firefox w/o snap ubuntu 22

Snap sucks.  Firefox under snap sucks worse.  

Blocks access via links to local storage, which might seem useful, but is poorly executed with the snap solution.  

When updates are due, locks up firefox and forces a restart at the convenience of the update.  Again seldom happens at a good time.

Rather than install a down rev of ubuntu, the build with a deb install is available, no snap.
