That’s extremely weird, I’ve never heard of Firefox not letting you browse until you update. When snap auto-updates Firefox there’s usually a notification bubble asking to close your browser to update but you can dismiss it and keep browsing in my experience.

This isnt even a unique or uncommon type of guy Lol you find these dudes everywhere at Hypebeast stores and corner store vape shops

The hate for snap on Linux forums always felt weird to me, I’ve literally never had issues with Firefox snap. I understand being frustrated with it on the principle that it feels Windows-y to force it on the system, but the Firefox snap is packaged by Mozilla and bundles the latest Mesa libraries instead of using the older libraries from the Debian repos that don’t have the latest performance fixes, so its also faster than installing through .deb. And Mozilla has Debian repos for Firefox you can add to your sources.list if you really insist. There’s also nothing preventing you from installing Flatpak and using that on Ubuntu.
