Firefox hangs with upload file dialogue, also after reset + no-plugins + restart + removing sqlite dbs (sigh)

more options

I've tried resetting firefox, removing all Add-ons/plug-ins, removing sqlite dbs, restarting. Nothing makes any difference. As soon as the kmozillahelper file system dialogue pops up, sometimes immediately, and sometimes after several seconds, Firefox freezes permanently. I have to kill the process and restart Firefox to proceed.

ps. I've seen these posts from 2012 and 2014, and the issue is still NOT fixed:

What is the web site adddress and the file you are trying to download?


Start Firefox in Safe Mode {web link} While you are in safe mode;

Type about:preferences<Enter> in the address bar

Select Advanced > General. Look for and turn off Use Hardware Acceleration.

Poke around safe web sites. Are there any problems?

Then restart.

What is it that happens, error messages, anything else?

As per the original ticket: As soon as the kmozillahelper file system dialogue pops up, sometimes immediately, and sometimes after several seconds, Firefox freezes permanently. I have to kill the process and restart Firefox to proceed.

Additionally: There are no error messages of any kind. Neither in the GUI, nor in /var/log/messages. Nada, nix, just everytime I try to upload a file, Firefox freezes permanently (until I kill + restart Firefox).

Sadly :(

I guess the 'kmozillahelper file system dialogue' is the window which pops up after pressing a 'Browse' button in order to select a file from the file system? It's more likely that this is an OS problem, where the OS is trying to query destinations not immediately available, e.g. like a network share, or a Bluetooth service, as described in one of the links you posted above.

Does this problem only occur with Firefox? Have you tried a different browser, or do you see this with other applications as well?

Yes, Christ1, I can browse the file system for a file/photo to upload. Although only for a few seconds, and then Firefox freezes. It's very odd.

I agree that it sounds like some interaction with the firefox/kmozillahelper/sys. app. thingy. I have tried a clean chrome download, and the identical file upload, (site/image combo), works perfectly from there...

Interestingly... using a different user account with the same Firefox installation works fine. *also* using a different user PROFILE with the same Firefox installation works fine too. What I do is this:

 firefox --new-instance -Profile_Manager

profile-1 works fine. profile-2 fails with file upload browser window freeze. profile-3 works fine. profile-4 works fine. profile-5 fails with file upload browser window freeze. profile-6 works fine.

What is it about 2 and 5 that is differeent from the others? Add-on, setting, permissions . . . .

Just curious, where did you pick up the --new-instance command line argument? It isn't very well documented, if at all. Typically you'd use the -no-remote option to start a new instance. http://kb.mozillazine.org/Command_line_arguments

Let's not go off-topic here, @christ1, but I refer you to the official bug report which discusses "Create a -new-instance flag for the functionality of the old -no-remote flag."

 https://bugzilla.mozilla.org/show_bug.cgi?id=716110

It seems like which flag you choose to use, might depend on which bug report you read ;)

ps. inspecting profile differences...
