Firefox tab crashes

ben706 · 2017-07-31 21:37

Greetings,

I have the latest edition of Firefox running on q4os, have recently uninstalled and reinstalled, and keep getting tab crashes. "Gah...your tab has crashed" error. It has been hard to me to replicate consistently, but happens to the point where Firefox is not usable. Any ideas??

Thanks,

Ben

First you could try to remove user cache and firefox data and perform a test run. Note, this action would reset firefox to the initial state. Navigate to your home directory and move firefox data directory '$HOME/.mozilla' to somewhat else. Following terminal commands will do the job:
$ cd $HOME
$ mv .mozilla .mozilla-backup

Now run firefox from command line and watch output for errors preceding the crash:
$ firefox

Please post back a result of the test run.

You can simply restore original data moving '.mozilla-backup' directory back to '.mozilla'

EDIT: instructions fixed

Take a look at this support post from Mozilla and see if it helps,

OK....here is what I got in my terminal window when the tab crashed:

###!!! [Parent][MessageChannel] Error: (msgtype=0x2C0085,name=PBrowser::Msg_Destroy) Channel error: cannot send/recv

Does this tell anyone anything?

Thanks Crosscourt....I'll chase some of that info too!

Oh geez...it may have been the hardware acceleration issue....I swear I tried to find that recently and could not...and then read somewhere that firefox did not offer the option by default in it's linux releases.....well....we shall see if that does the trick!!!

crosscourt · 2017-08-01 01:01

Hardware acceleration is one of the most common issues and we many times recommend turning it off but in your case it could have been other things easily.
Hardware acceleration is on by default so users need to be aware that it could be a problem.

Hope it works out!

Still got a damn tab crash...but if definitely helped stabilize things. I'll see what happens in the next few days.

ben706 · 2017-08-01 04:30

Still crashing.....now regularly again. It's a fresh install...no add ons, etc...yet seems stable in safe mode. I can't figure this one out.

@ben706
We will try to investigate this issue in more detail, so we would need some more info to be able to reproduce it. Please specify:

- CPU architecture
- Short specification of your hardware
- Exact firefox version
- Exact Q4OS version, run 'get-q4os-version' command from terminal
- Which way did you install firefox ? Software centre, package manager, other ?

q4osteam · 2017-08-01 10:10

Anybody else noticed this issue within Q4OS ?

Yes, I get crashes now and again. Annoying!

Dai_trying · 2017-08-01 14:12

I've been using Pale Moon for about a month or so with no issues...

crosscourt · 2017-08-01 17:49

I use Firefox all the time and havent had any issues with Q4OS or any other distro and Windows.

Crashes arent exclusive to Firefox either as recently Chrome users have been complaining about similar crashes with Linux and windows.

Since its stable in safe mode , disable all extensions/addons/plugins, make sure to use the default theme and turn off hardware acceleration and see what happens.

An interesting experiment might be to try Pale Moon and see if it has similar issues to Firefox as its forked off of Firefox.

bin · 2017-08-02 06:13

Palemoon works pretty well. I've had occasional lockups but normally that's on sites with some very bad javascript.

Firefox - I've given up using it - it is sooooo slooooowwwww it feels like one long crash.....That applies to both ESR and mainstream releases. The only addons I have are https everywhere, ublock origin and oldbar. Hardware accel always disabled. Having said that, I'm using old hardware so it may just be one of those things. TBH I've been using Seamonkey as my main web tool for so long I dread those odd sites which only render properly under Firefox - and for those I'm finding Palemoon a good alternative.

crosscourt · 2017-08-02 17:59

Firefox 54 is pretty quick and you would be surprised how well it does compared to other browsers.

The issue here is Firefox isnt the only browser that crashes but overall Opera has been the most stable for me.

ben706 · 2017-08-03 03:50

Any clues?

bin · 2017-08-03 06:36

A quick search on Google reveals a number of variations on this theme ranging from Java issues to gecko drivers

You said you had started in terminal to get the error, but did you follow the dev team recommendation to rename your profile folder? This will force a clean profile which can help identify cruft/issues with your current profile

As you haven't mentioned any specific site I take it this just happens at random - if it comes up when you start FF with no profile then it is very odd. Starting with no profile, in terminal type 'firefox www.linuxtoday.com' What I'm looking at here is if there is something in FF first run that is causing this - just say Not Now to default browser question.

The exact error code produces one solution which you can try easily

Open Firefox
In the address bar type 'about:config'
Clear the warning
In the search bar type 'browser.tabs.remote.autostart'

This should produce 2 results:-
browser.tabs.remote.autostart
browser.tabs.remote.autostart.2

Set both values to 'false'

Restart Firefox.

If you're still having problems go to address bar and type 'about:support'

There's a button at the top of the screen - Copy Text to Clipboard. Paste that text into a text file and attach it so we can take a look.

@ben706
We are not able to reproduce the issue so far. Please read and try to follow bin's advice in #19 just post above http://www.q4os.org/forum/viewtopic.php?pid=8736#p8736 as exact as possible, and then post results here.

@bin
Thanks for these valuable suggestions.

ben706 · 2017-08-03 21:12

Aw jeez..I never did do the test run thingie. Ok...when I do that..rename the profile folder and run firefox from the terminal here is what I get in the terminal window: (firefox-esr:26365): GLib-GObject-CRITICAL **: g_object_ref: assertion 'object->
ref_count > 0' failed

That line was repeated numerous times in the terminal...then this stuff too:
1501790886150 addons.update-checker WARN Update manifest for webcompat@mozilla.org did not contain an updates property
1501790886162 addons.update-checker WARN Update manifest for firefox@getpocket.com did not contain an updates property
1501790886182 addons.update-checker WARN Update manifest for aushelper@mozilla.org did not contain an updates property

I'll try what bin instructed above as well.

ben706 · 2017-08-03 21:33

OK...followed the instructions from bin and now firefox seems to shut down completely....when i reopen I get this:
Well, this is embarrassing.

Firefox is having trouble recovering your windows and tabs. This is usually caused by a recently opened web page.

You can try:

Removing one or more tabs that you think may be causing the problem
Starting an entirely new browsing session

I attempted to go to about:support but the crashes the browser as well.

Does any of this behavior give some clues?

Thanks for the help and the patience!

crosscourt · 2017-08-03 22:18

Can you start an entirely new browsing session?

Did you disable all extensions,plugins/addons,use default theme and turn off hardware accel?

Have you tried another browser like Chrome or Chromium and does your system crash with those browsers?

Its stable in safe mode based on your comments.

Yes to all of the above, except Chrome does not crash. Just to be clear, it is not crashing the system, just the browser itself.

ben706 · 2017-08-03 23:32

I do get a crash report when I attempt to go to about:support, if that would help.
