How to uninstall Firefox package downloaded from Mozilla

I use Brave browser in Ubuntu to access nsandi.com bank web page but today I received an error that it was taking to long to download the web page.

I checked nsandi.com's web page and they have instigated two factor security which requires particular browsers and OS. Linux Brave was not among them.

I also had Firefox installed in Ubuntu via snap but it was not the latest version required by nsandi.com. I uninstalled the snap version, downloaded and installed the latest package from Mozilla, following the instructions on their download page. Lo and behold, it was the same version as that I had uninstalled from the snap.

nsandi.com think they may have a problem and are looking into it, so, after all, if the problem is their end then the snap version may work.

I cannot find the same Mozilla instructions I used but this is what I did:

mkdir -p ~/bin
tar -xf /home/makem/Desktop/firefox-115.0.2.tar.bz2
tar -xf /home/makem/Desktop/firefox-115.0.2.tar.bz2 --directory ~/bin

The executable is ~/bin/firefox/firefox

I would like to uninstall that package and reinstall the snap from repos.

Just remove the ~/bin directory with:

rm -r ~/bin

You shouldn't use this directory name to put the application, it's confusing. See this.
