I followed the instructions on Mozilla support website:

Install Firefox .deb package for Debian-based distributions (Recommended)

To install the .deb package through the APT repository, do the following:

  1. Create a directory to store APT repository keys if it doesn't exist:

    sudo install -d -m 0755 /etc/apt/keyrings

  2. Import the Mozilla APT repository signing key:

    wget -q https://packages.mozilla.org/apt/repo-signing-key.gpg -O- | sudo tee /etc/apt/keyrings/packages.mozilla.org.asc > /dev/null

    If you do not have wget installed, you can install it with: sudo apt-get install wget

  3. The fingerprint should be 35BAA0B33E9EB396F59CA838C0BA5CE6DC6315A3. You may check it with the following command:

    gpg -n -q --import --import-options import-show /etc/apt/keyrings/packages.mozilla.org.asc | awk '/pub/{getline; gsub(/^ +| +$/,""); if($0 == "35BAA0B33E9EB396F59CA838C0BA5CE6DC6315A3") print "\nThe key fingerprint matches ("$0").\n"; else print "\nVerification failed: the fingerprint ("$0") does not match the expected one.\n"}'

  4. Next, add the Mozilla APT repository to your sources list:

    echo "deb [signed-by=/etc/apt/keyrings/packages.mozilla.org.asc] https://packages.mozilla.org/apt mozilla main" | sudo tee -a /etc/apt/sources.list.d/mozilla.list > /dev/null

  5. Configure APT to prioritize packages from the Mozilla repository:

    echo '
Package: *
Pin: origin packages.mozilla.org
Pin-Priority: 1000
' | sudo tee /etc/apt/preferences.d/mozilla

  6. Update your package list, and install the Firefox .deb package:

    sudo apt-get update && sudo apt-get install firefox

So now I have:

$ apt list --installed | grep firefox
firefox/mozilla,now 132.0~build1 amd64 [installed]

$ snap list | grep firefox
firefox                    131.0.2-1                    5091   latest/stable
mozilla**         -

I don't mind having both apt and snap versions installed on my system. The problem is the apt version gets uninstalled when a software update is done even though the "Configure APT to prioritize packages from the Mozilla repository" step was done.

How do I stop the apt version being uninstalled and replaced by snap from software updates?

I'm using Ubuntu 20.04.6 and have been experiencing intermittent Wi-Fi disconnections during which my Wi-Fi icon turns into a question mark.

I was able to get all the below information before my WIFI automatically reconnected:

Why does my Wi-Fi get disconnected?

I edited /etc/default/grub and changed the line:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

to:

GRUB_CMDLINE_LINUX_DEFAULT=""

Then ran sudo update-grub and rebooted.

Ramdisk messages display like this during boot:

enter image description here

But the boot messages display correctly:

enter image description here

If I go into "recovery mode", Ramdisk boot messages display correctly. Is there a setting I am missing? I did not have this problem when I was running Ubuntu 18.04.6.

As requested, Here is my CPU info:

I am using a repeater on my network. My system settings only shows one device name for a WIFI connection. It is defaulting my WIFI connection to the repeater instead of my router. iwlist scan shows both the repeater and router. How do I change my default connection to my router? Im guessing by MAC address somehow?

nmcli device wifi list returns-

enter image description here

My system is picking the weakest signal but the highest rate. I don't want that. My router is 10 feet away from my laptop.

Here is the short version of iwlist:

iwlist scan

It is MAC C0:C5:22:4C:9E:D0 that I prefer to connect to.
