Removing Firefox Mate screen from Ubuntu Mate

I’m using Ubuntu Mate 21.10.

I’ve recently installed Ubuntu Mate and I love it. I use firefox as my primary browser. Ubuntu Mate uses a custom type of Firefox theme/package which opens the Mate welcome screen at start-up. I like it but I’d rather use the default Firefox.

This installation was done by installing the ubuntu-mate-desktop^ package in Ubuntu 21.10.

Is there any way I can install the normal firefox on my Ubuntu-mate?

Here is the image of what it looks like (this image is taken from an external website):

I got my answer on Ubuntu MATE Community.

As Norbert_X (Popularly known as N0rbert on Ask Ubuntu) said in his reply to my thread :

You can override such behavior by removing two files using terminal commands:

sudo rm -v /usr/lib/firefox/ubuntumate.cfg /usr/lib/firefox/defaults/pref/all-ubuntumate.js

and then restart Firefox.

Please note, that we do not pin/lock the ubuntu-mate-default-settings corresponding package version, so you should apply the above fix again when Ubuntu MATE 22.04 LTS will be released.
