I use Firefox in Ubuntu (actually, Zorin). FF doesn't start correctly intermittently (greyed out; can't get URLs). But it works if I log out & back in. Ideas?
The clue is that it works without a hitch when this flares up by simply logging out then back in.
I'm new to Ubuntu. I'm actually using the Zorin fork of Ubuntu, which uses a Gnome rather than Unity interface. But for all practical purposes, it's Ubuntu I'm Firefoxing with as an Ubuntu newbie.

about:config > browser.tabs.remote.autostart = false
reconciled these inconsistencies, so all's well in paradise. =)

Be aware that Ubuntu builds its own version of Firefox from source code, so there are some differences between their version and the Linux version that Mozilla builds and distributes. http://ubuntuforums.org/
Just a SWAG:
See if disabling Use hardware acceleration when available helps with that fault.

Thank you kindly for the response. I use the Linux version. I tried those preference tweaks, including the the proxy, IPv6 & disablePrefetch as described in https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can to no avail. BTW, when it flares up, even about:config & preferences are grey-out/inaccessible.
THE GOOD NEWS: upon closer examination, I was able to get this error info to relay:
Failed to connect to Mir: Failed to connect to server socket: No such file or directory Unable to init server: Could not connect: Connection refused
(/usr/lib/firefox/firefox:22345): Gtk-WARNING **: cannot open display: :1 [Parent 22275, Gecko_IOThread] WARNING: pipe error: Broken pipe: file /build/firefox-CIsUqV/firefox-60.0.2+build1/ipc/chromium/src/chrome/common/ipc_channel_posix.cc, line 709 [Parent 22275, Gecko_IOThread] WARNING: FileDescriptorSet destroyed with unconsumed descriptors: file /build/firefox-CIsUqV/firefox-60.0.2+build1/ipc/chromium/src/chrome/common/file_descriptor_set_posix.cc, line 22
I got that by entering
firefox -P
at the command prompt, then "start Firefox".
It then complained at me things like:

Then that

I'm not sure, but I'm hoping that https://github.com/SeleniumHQ/docker-selenium/issues/388 has a working fix:
workaround is to disable remote autostart: in: about:config set (historical mode):
browser.tabs.remote.autostart = false <--------------------------- <--------- (also browser.tabs.remote.autostart.2 = false if applicable)
So far, so good. I don't understand why it works, but would like to know. I know it's common enough of a problem, somebody someday may see this and benefit from it.
If it flares up again, I'll come crying back here and strike that.
Happy Fourth!
