Firefox freezes in foreground

While using Firefox actively, it freezes. I can't scroll, nor can I interact in any other way with it. Although it seems like actions are passed through to the program. For example, I am somewhat able to switch tabs, because the view gets updated when the focus of the window is switched to another app.

I am on Ubuntu 22.04.1 LTS and using Firefox (snap) v106.0.5. My extensions are: NoScript, Privacy Badger and uBlock. My hardware is a Lenovo IdeaPad Flex 3 11ADA05 (GPU: Picasso/Raven 2, CPU: AMD 3020e). WM is stock and I'm using Wayland.

For now it seems, that the problem appears to be a lot less often, when Firefox is launched via command line. If it happens, there are no real log entries about it. I've also followed the hints given from the mozilla troubleshooting page.

Disable extensions
Update extensions
Use default theme
Start with safe-mode

Does someone have any clues at hand and is willing to share them?

Edit: I am now testing, if the apt version works better. Steps taken:

> cp -R ~/snap/firefox ~/ffback
> sudo snap remove firefox
> sudo add-apt-repository ppa:mozillateam/ppa
> echo '                                     
Package: *
Pin: release o=LP-PPA-mozillateam
Pin-Priority: 1001
' | sudo tee /etc/apt/preferences.d/mozilla-firefox
> echo 'Unattended-Upgrade::Allowed-Origins:: "LP-PPA-mozillateam:${distro_codename}";' | sudo tee /etc/apt/apt.conf.d/51unattended-upgrades-firefox
> sudo apt install firefox
> cp -R ff_backup/common/.mozilla/firefox ~/.mozilla/
> # start firefox open about:profiles
> # set old restored profile to default
> # restart a few times

Restoring the apt version of firefox has completely mitigated the issue and even made it a little bit more responsive.

Again, needed steps are below:

> cp -R ~/snap/firefox ~/ffback
> sudo snap remove firefox
> sudo add-apt-repository ppa:mozillateam/ppa
> echo '                                     
Package: *
Pin: release o=LP-PPA-mozillateam
Pin-Priority: 1001
' | sudo tee /etc/apt/preferences.d/mozilla-firefox
> echo 'Unattended-Upgrade::Allowed-Origins:: "LP-PPA-mozillateam:${distro_codename}";' | sudo tee /etc/apt/apt.conf.d/51unattended-upgrades-firefox
> sudo apt install firefox
> cp -R ff_backup/common/.mozilla/firefox ~/.mozilla/
> # start firefox open about:profiles
> # set old restored profile to default
> # restart a few times

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
