From the last updates, Firefox enters in crash also in safe-mode.
"I think" that the problem comes from the plugins, when you walk into some multimedia content websites, it enters Crash!!!
To see the plugins are updated:
Adobe Flash this Player is updated and QuickTime Plug-in is potentially vulnerable and not as updating it.
The unknown Plugins:
-Windows Media Player Plug-in (v. ) Gecko Media Player 1.0.8
-mplayerplug-in is now gecko-mediaplayer 1.0.8 (v. ) Gecko Media Player 1.0.8
-RealPlayer 9 (v. ) Gecko Media Player 1.0.8
-IcedTea-Web Plugin (using IcedTea-Web 1.5.3 (1.5.3-0ubuntu0.14.04.1)) (v. )
-DivX Browser Plug-In (v. ) Gecko Media Player 1.0.8
They say "search" and not be as update them.
Thank you,

I'm assuming you're useing a LiveCD installation.

Next time it crashes, open a terminal and look to see it the USB device is full.
df -h
When there is no longer any room on the device, things break.

I'm not using LiveCD installation.

I have installed Navegatrix on the Hard Disk, have 60 Gb free,

I'm sorry, I'm not clear on the nature of the problem.

This also applies to what you are saying about the plugins, if you've have enabled, disabled, or attempted to upgrade them.

I guessed and made a number of attempts to get it to break on multimedia content, but nothing jumped out.

I can't replicate it here.

I have installed Navegatrix in two Computers and the same thing happens!
It tries to view this video:

This has been interesting so far. I could not figure out what you were talking about.

I update Firefox and the plugins, but still nothing.

Your video link however crashed everything when trying to view the embedded YouTube video.
The video on YouTube itself crashes Firefox. Some videos knock it out, others did not.

The long story short, hours later I get it to work, but in the endI was a little sloppy in procedure and remembering specifics.

Troubleshooting is a lot like metaphysics, or most anything....if you loose your bearings you're likely to run in circles or off a cliff.

Rather than be befuddled, to rule out false steps, or overlooking a critical point, I started over.

But this is where I thought it got interesting. Navigatrix out of the box doesn't crash on the videos.

As you said, updating introduced the bug. But where? A lot of people are sporadically reporting this (or similar) problem in other distributions with sporadic success. I think someone some where introduce a default setting that shouldn't be.

I'll finish re-introducing the bug, and see if I can replicate the fix. will just have to wait until tomorrow.

To reduce the amount of downloading I updated just Firefox. Nothing.

I update every package related to Firefox. Nothing

I blanket upgraded everything
sudo apt-get update && sudo apt-get upgrade

The video runs smoothly in an blanket upgrade.

Now, it really will have to wait until tomorrow.

Sorry for the delay, it wouldn't break. It's hard to intelligently break something.

Try this
  • Open the browser and
  • Put about:config and <enter> into the URL box. #1
  • Swear you're responsible, and
  • enter gmp into the search. #2
  • Toggle(Click) the highlighted selection to true. #3
  • Clear your cache, restarting Firefox for good measure, because voodoo maybe involved and
  • give it a go.

For other people, the videos
crash Firefox after updating. This may fix it.
if you're curious.

Well, I've tried with another computer and if found:
I changed the value to true
If you saw the videos worked without entering crash but after the last update of Firefox today, videos carsh!
There is a new line:
media.gmp-gmpopenh264.abi value x86-gcc3
We return to top,

Post subject:  Re: Firefox - crash

There are things going on that I can't see. I have no idea why the new line appeared. I do not have anything similar.

Try this:
sudo apt-get update && sudo apt-get install firefox
This ensures you have the latest version of Firefox.
mv ~/.mozilla ~/.mozilla.original
This moves all your Firefox configuration files to a new directory. This isolates a possible source of the problem.

Launch Firefox and go to

It will crash.

Launch Firefox again. This time about:config and toggle the media.fragmented-mp4.gmp.enabled to true

Go back to the video. Firefox does not crash.

Move your Scrapbook, Bookmarks, etc. to the new profile. Delete the remainder.

rm -rf ~/.mozilla && mv ~/.mozilla.original ~/.mozilla
to restore it the way it was and keep looking for a solution.

I have made instructions and anything,
Firefox version is 44.0
the code:
mv ~ / .mozilla ~ / .mozilla.original
rm -rf ~ / .mozilla && mv ~ / .mozilla.original ~ / .mozilla
says: No such file or directory
I reinstalled Navegatrix Hard Disk and updated the software and the problem persists.
In the Notebook is no longer in the line:
missing after the code:
sudo apt-get update && sudo apt-get install firefox
Firefox version is also 44.0
In the two computers this:
gmpopenh264.abi value media.gmp-x86-gcc3
I do not understand how the crash of Firefox only affect me.
Thanks Noe,

says: No such file or directory
This should have never happened.

By moving the .mozilla directory (mv ~/.mozilla ~/.mozilla.original) Firefox has no profile.

When Firefox has no profile, it re-creates one when it is re-launched.

So now you would have 2 directories .mozilla and .mozilla.original.

rm -rf ~ / .mozilla && mv ~ / .mozilla.original ~ / .mozilla
Removes the first directory and after doing so, successfully (&&) moves the original directory back to where it was before you started.

No such file or directory tells us that something went wrong.

Re-installing may or may not do the same process (except without the ability to restore), I think it should, but it I can't tell, nor can I tell why you are having trouble finding
or that your
gmpopenh264.abi value media.gmp-x86-gcc3
it not the same as mine
media.gmp-gmpopenh264.abi; user set; string; x86-gcc3

I've got also a problem with firefox,it crashes very often, specially when I try to open a window in facebook to play scrabble, this is not very important so I didn't ask about this until I read this subject in the forum.

It's much better since I made the last update and delete a firefox extension (globefish instant translator) but now I'can't find how to install dictionnaries , should I open a new message?

Yes, the browser has gotten pretty complex, and stapling extensions on can make it unstable.

Dictionaries are two matters, and I'm not sure which one you are after.Enter about:addons to the URL box and <Enter>

Same for me, Firefox crashes when opening a link from an email (Facebook notification, Youtube etc.)
I've installed Chromium, no problem from the same email.

Edit : I did not found :
media.fragmented-mp4.gmp.enabled when searching "gmp".

Searching in Firefox where the problem is.
Have a nice day,

Hi all, I have had the same problem. A hard drive installation of Navigatrix (Jan2017) works fine with facebook and with youtube, but as soon as I do the online updates, Facebook crashes constantly and instantly, but oddly enough sometimes it works out of the blue for a good while.

I have no Firefox add-ons installed, and a brand new unmolested installation (apart from Skype installed). I'm using an Acer Aspire One 32bit in case it makes any difference.

I have looked on the web and found that Firefox has problems, especially with Facebook and there are various solutions noted:I have a tried a good many of them (not all, as there are loads) to no avail. What I would note is that Firefox's helpsite says that on Firefox 51 (the newest release) one should go via several sub menus to a toggle to switch on/off Java to see if it works then. But the toggle for Java (or was it Javascript, can't recall which now) is not where it is said to be... so Firefox appear to have made a mistake on their site. I haven't found out how to switch java/script on or off anywhere yet on this version so have not idea if that is in fact the problem. But the point is the problem may not be limited to use in Navigatrix.

Not much help I know...

thanks Moe for the support and hard work as always, cheers all.
