I have tried uninstalling Firefox and reinstalling. Tried holding shifting and clicking the firefox app button to start in safe mode. Doesn't work.

This behavior started after I signed up for Firefox Sync so I suspect it has something to do with that. After reinstalling I tried deleting xulstore.json in %APPDATA%\Mozilla\Firefox\Profiles but still firefox won't open. Any ideas?

this morning, I get the above error message when attempting to open ff. I was able to open ff from the start menu(windows 7 enterprise), but all of my bookmarks have disappeared. I had the system administrator attempt to restore my computer, with no results, then reinstalling ff. upon reinstall, I was able to open ff, but bookmarks were still missing. then, a ff update "esr" was run, and now I get the error msg above trying to open ff from anywhere. I cannot open ff at all to restore defaults or run in safe mode to fix.

Using Ubuntu 18.04, 4.15.0-33-generic GNU/Linux, and Mozilla Firefox 67.0. Other browsers work fine, so it is not an internet connectivity issue. Firefox uses no proxy, and has IPv6 disabled. It cannot open a local server like 192.168.1.4, so it is not a DNS resolution issue. If I run it from CLI, I get the following:

Sandbox: seccomp sandbox violation: pid 25975, tid 25983, syscall 53, args 1 1 0 139885284952128 0 139884708835328. [Child 25975, Socket Thread] WARNING: Unable to create pipe named "25975.45.480528193" in server mode error(Function not implemented).: file /build/firefox-xkwMhH/firefox-67.0+build2/ipc/chromium/src/chrome/common/ipc_channel_posix.cc, line 210

Happens after a recent update, so may go back to earlier version.

Firefox (Quantum versions only!) keeps instant crashing on startup even in safe mode without crash reporter opening. Removed profile and any Firefox related files. Clean install made numerous times. Launching on fresh Administrator user account on affected computer also didn't solve crashing. Also crashes in safe mode. Tried everything. Nothing helps. I have switched to chrome after Firefox Quantum release because of this. I can perfectly run any firefox on virtual Windows 7 and other computers.

I Repeat - crash reporter also won't open. Windows error reporting shows following:

Specs are: OS: Win 7 SP1 64 bit CPU: Core I5 3470 RAM: 16GB I have enough space :)

Please help, as chrome is becoming more and more annoying to use and I want to swith back to my beloved Firefox♥

I'm using firefox developers edition, and after one of the updates (unsure which one) it does not restarted after updating. After I click on Firefox icon I can see two firefox processes in task manager, but after some time they just quit, without showing any window or even error message. I tried to enter safe mode by pressing "shift" while starting firefox - no result, processes quit before even showing dialog about entering safe mode. I tried to uninstall & install firefox back - still the same result. I removed profiles in "cd %APPDATA%\Mozilla\Firefox\Profiles\" - still the same. There are two records in windows logs upon each start attempt:

I don't even have idea where to start looking for the actual reason.
