How did it break config? Is this a dual or multi monitor setup?

There have been issues with multi monitor placement, primary display setting etc that can get pretty fiddly to solve - seen it with different distros over many years of NVIDIA proprietary driver use.

There is no install needed, you can just edit permissions and make the file executable and then when you open it or click it the app runs.

What won’t be created by default is an application menu to run it from whatever desktop environment you use. You can create those if you wish. You can create a launcher in the menu manually, or you can use a tool called AppImageLauncher to create these for you.

There’s a pretty good explanation here: https://askubuntu.com/questions/1311600/add-an-appimage-application-to-the-top-menu-bar

Trust. I think it has been earned - so far. NCSA Mosaic was my second browser, and while I’ve experimented with all the major browsers and many not-so-major contenders over the interim couple of decades, Firefox has been a constant for me ever since it was first spawned off of Mozilla. I still believe the Firefox team when they say things, and so far that has worked out just fine.

Are you viewing dynamic or static content? For me, the difference is huge with games, etc but harder to tell with static images.
