If you switch to the APT version, you will lose the bookmarks in the snap version unless you sync them with your Firefox account, or export them manually.
The other answer by Organic Marble is for Firefox-ESR, and the answer by eddygeek is for the beta version.
This answer is for the latest stable version of Firefox. You can use the Firefox PPA maintained by Mozilla team.
sudo add-apt-repository ppa:mozillateam/ppa
Then, copy and paste the following code in a terminal in one go (don't copy-paste line by line) to prioritize the apt version of firefox over the snap version.
echo '
Package: *
Pin: release o=LP-PPA-mozillateam
Pin-Priority: 1001
Package: firefox
Pin: version 1:1snap1-0ubuntu2
Pin-Priority: -1
' | sudo tee /etc/apt/preferences.d/mozilla-firefox
Next, remove the snap version of firefox
sudo snap remove firefox
If you see the following error,
error: cannot perform the following tasks:
- Remove data for snap "firefox" (1943) (unlinkat /var/snap/firefox/common/host-hunspell/en_ZA.dic: read-only file system)
Then run the following commands (source) to disable the hunspell service, and try removing Firefox snap once again.
sudo systemctl stop var-snap-firefox-common-host\\x2dhunspell.mount
sudo systemctl disable var-snap-firefox-common-host\\x2dhunspell.mount
sudo snap remove firefox
Install Firefox with apt.
sudo apt install firefox
To ensure that unattended upgrades do not reinstall the snap version of Firefox, enter the following command. Alternatively, you can turn off unattended upgrades.
echo 'Unattended-Upgrade::Allowed-Origins:: "LP-PPA-mozillateam:${distro_codename}";' | sudo tee /etc/apt/apt.conf.d/51unattended-upgrades-firefox
To undo these changes
- Remove the firefox PPA.
sudo add-apt-repository -r ppa:mozillateam/ppa
- Remove the apt pin.
sudo rm -rf /etc/apt/preferences.d/mozilla-firefox
- Remove the apt version and reinstall snap.
sudo apt remove firefox && sudo snap install firefox

Yes. Snap ignores your theme and selects one of the co-packed snap themes. This is one of the drawbacks of snap.
You could remove Firefox from snap with:
sudo snap disable firefox
snap remove --purge firefox
For Ubuntu 22.04, the empty Firefox Deb is pre-installed as a wrapper. You have to remove it via command:
sudo apt remove --autoremove firefox
On Ubuntu 22.04, you'll have to add a ppa now:
sudo add-apt-repository ppa:mozillateam/ppa
Now you can install it as deb:
sudo apt install -t 'o=LP-PPA-mozillateam' firefox
To avoid clashes during the next updates you might setup the priority in the mozillas ppa file:
sudo nano /etc/apt/preferences.d/99mozillateamppa
Below the existing lines add the following entries:
Package: firefox*
Pin: release o=LP-PPA-mozillateam
Pin-Priority: 501
To block Ubuntu's own (empty) deb add these lines as well:
Package: firefox*
Pin: release o=Ubuntu
Pin-Priority: -1
This all has been explained here in detail
I removed snap altogether, because I want to have the freedom to decide about the look & feel of my desktop - uniformly ;-)
