If anybody else still experiences this issue I would recommend that they file a new bug report.

It won't even let me check for updates for plugins and gives an error for that. I have tested with other applications such as ping and the internet connection is fine, it's just Firefox which loses it. I have noticed that when I run firefox from Terminal that this is the output to begin with: 1482487989643 addons.webextension.fire...@ghostery.com WARN Loading extension 'fire...@ghostery.com': Reading manifest: Error processing background.persistent: Event pages are not currently supported.

Promise resolved after context unloaded Then when the problem starts to occur, I find that the only way to resolve it, if even for a short period, is to restart the browser, so I tell Firefox to quit, however although the window does close, the process carries on and this is the output: tabs.onRemoved event fired after context unloaded. tabs.onRemoved event fired after context unloaded. tabs.onRemoved event fired after context unloaded. console.error: Message: Error: SessionFile is closed Stack: SessionFileInternal.write@resource://app/modules/sessionstore/SessionFile.jsm:315:29 this.SessionFile.write@resource://app/modules/sessionstore/SessionFile.jsm:76:12 SessionSaverInternal._writeState@resource://app/modules/sessionstore/SessionSaver.jsm:259:12 SessionSaverInternal._saveState@resource://app/modules/sessionstore/SessionSaver.jsm:230:12 SessionSaverInternal._saveStateAsync@resource://app/modules/sessionstore/SessionSaver.jsm:243:5 SessionSaverInternal.runDelayed/this._timeoutID<@resource://app/modules/sessionstore/SessionSaver.jsm:147:40 setTimeout_timer@resource://gre/modules/Timer.jsm:30:5 ExceptionHandler::GenerateDump cloned child 12324 ExceptionHandler::SendContinueSignalToChild sent continue signal to child ExceptionHandler::WaitForContinueSignal waiting for continue signal... I am then told that Firefox crashed and asked if I would like to submit a report, so far I have told it to submit a report three times as the crash has occurred that number of times.

I am running Ubuntu GNOME 16.10 with GNOME 3.22 and Firefox 50. Although I am sad to say this, if I don't find a solution for this issue soon I am at least temporarily going to have to switch browsers because Firefox is seriously becoming unusable with this issue.
