Hi

Have you set a .shortcut file for the copy that you have installed?

What desktop environment are you using?

It's not "installed" (as far as Ubuntu is concerned.) There's nothing to form a shortcut to.

The program only runs if launched from the Terminal using the aforementioned command line.

I attempted to simply paste the command to a text file saved to the desktop, set "Open with" to Terminal and set the file to "Run as program", but that does absolutely nothing. :(

I'm using the default Ubuntu desktop.

I'm in KDE and have Nightly pinned. see screenshots

Thx for the reply, but I've tried KDE and had too many problems with it. :(

Is there a way to fully "install" the "Nightly" build? No "installer"/setup utility is included with the download.

My install of Firefox was somehow corrupted. I was instructed by FF tech support to download the latest "Nightly" build,

You should use the current Release from www.mozilla.org/firefox/all/ or Beta channel builds (a version can get get say 9 to 14+ builds on beta channel) at most but if you want to continue using the unstable Nightly channel builds.

The tarbal are basically just extract and run the firefox .sh and use Firefox. There is no installer or setup for the Linux tar builds from Mozilla. You have to manually create a desktop or panel or menu launcher to the firefox .sh in the Firefox folder. You can find a Firefox icon to use in the Firefox folder firefox/browser/chrome/icons/default

Also if you want updates for the Fx Linux builds from Mozilla you need to make sure the Firefox folder has user read/write permissions as many often put the Firefox folder in Home to make it easy if you are the only user.

Mozilla does not have any one on one support by phone, chat or email if that is what you mean by instructed by Fx tech support. https://support.mozilla.org/en-US/kb/avoid-and-report-mozilla-tech-support-scams

Not sure what Fx tech support you are referring to but nobody should tell an average Firefox user to use the unstable Nightly development channel builds that can get checkins and updates twice a day. The Nightly channel are more for developers and testers in mind.

Sorry for the late reply (Linux is not my everyday OS.)

I downloaded the latest release (90.0) from your link, but I'm not finding a ".sh" shell file anywhere in the archive. I had previously downloaded v91.0 from the archives, but it didn't resolve my issue.

That is when I was directed by Firefox (Developer?) Support via GitHub to try the "Nightly" build, which runs/works, but only when run using the aforementioned command from the terminal.

The Ubuntu Updater used to include FF updates, but no longer. I can still find and launch FF from the "Activities" screen, but as noted originally, what launches is unusable with no apparent cause or fix.

It makes no sense to me that both "Chromium" & "Nightly" display just fine, but the only thing FF displays is a washed out (to the point of pure white) box with no visible controls. All attempts to reinstall it have failed b/c the Linux release does not include a Setup utility (the closest being "flatpak", which also didn't resolve the issue.)

Is there a way to perform a clean reinstall of FF?

PS: I tried launching FF in it's "safe mode" but it made no difference. Note the faded colors visible in the screenshot only became visible when the screenshot was taken. TIA

UPDATE: I just discovered something odd: If I launch "Nightly" using the noted MOZ Terminal command, it displays fine, but if I try to "Run" Firefox directly from the same location ("~/Downloads/firefox/firefox"), I get the same washed out window. What is different about launching "Nightly" using the following command that "fixes" the problem? (MOZ_ACCELERATED=0 MOZ_WEBRENDER=0 ~/Downloads/firefox/firefox)

Unless you specifically wish to use Nightly, have you tried the Snap version available in GNOME software in Ubuntu?

Thx for the reply.

Is this in the Ubuntu "Software Store" (satchel icon)? Because it does not list "Firefox".

Do I search for "Snap"? Is there a specific download link?

Yes, the Ubuntu Software Store.

Search for "Mozilla Firefox web browser". Under "details", it should list the "source" as being snapcraft.io.
