using Firefox with UT in 2021

For those attempting to use Firefox in UT, the one option currently available to us is to use it within a Libertine container. For many devices the Firefox 84 version that is in the default repositories will crash whenever a site is attempted to be loaded. However, Firefox-esr (extended support release) 78 works stably in my testing (although slowly, due to the lack of hardware acceleration for apps in Libertine containers currently).
arm64 version is here (scroll to bottom of page to find download links to the deb package in your language)
and armhf version is here -

I want to mention that for folks who do install Firefox-esr 78, if you go to update the packages in your Libertine container it is important to set Firefox to "hold" on any updates, so you don't end up replacing your Firefox with a current but unusable version.
The Terminal commands to enable this are:
$ libertine-container-manager exec -i xenial -c /bin/bash
# apt-mark hold firefox
To undo this hold enter:
# apt-mark unhold firefox
