Cannot install extensions in 155.9 ESR version

When attempting to install an extension and clicking on "Add to Firefox" the button is replaced with a "Cylon" throbber and the popup dialog asking to confirm the install never highlights the "Add" button. The browser will stay in this state indefinitely until the tab for the extension install is closed.

Could this be a permissions problem involving the ".mozilla" directory tree in the home directory? I've been having this problem regardless of the FF version for some time (going back to at least v110.x). The recent issue involves that 115.9 ESR version installed in Debian Bookworm.

TIA...

It wasn't a network problem.

I created a brand new account on the system and was able to install an extension in that account's FF just fine. Apparently, there was some corruption -- permissions screwed up, something -- that was preventing FF from installing extensions. After renaming my $HOME and creating a new, empty account home directory, FF installed everything I was looking to install perfectly.

Is there a given directory that I could tar up to preserve FF's settings so I don't have to re-create my entire desktop environment should FF decide there's a problem in the future? There's the ".mozilla" tree but I suspect there are items in other subdirectories that might need to be backed up.

It could be a network issue, try changing DNS over HTTPS (DoH) to "Off" or "Max Protection" and in Connection Settings change "Use system proxy settings" to "No proxy".
