1334748 - Version 51.0.1 doesn't display web pages (blank content) with AppArmor profile

Status: RESOLVED FIXED

(Firefox :: Security, defect, P3)

Attachment: 20170127_201436.jpg

User Agent: Mozilla/5.0 (Linux; Android 6.0.1; SAMSUNG-SM-G900A Build/MMB29M) AppleWebKit/537.36 (KHTML, like Gecko) SamsungBrowser/4.0 Chrome/44.0.2403.133 Mobile Safari/537.36

Steps to reproduce:

In Ubuntu, software updater updates once a week.  I ran a standard update, and noticed it contained a Firefox update. My homepage is Google, and it opened as black and white with no text (see image).   I restarted with add on disabled (safe mode), and still no text.  When I type in the Google search field, nothing shows up.

I tried some other websites, and still nothing.  The only one that works has no text, www.purple.com.

Another weird thing is that when you open a tab, like troubleshooting info, then switch back to the Google tab, the Google tab now shows the troubleshooting page.

Something is really wrong.  I hate having to try a reset because it screws everything up, if it even will fix this, and I don't think users should have to reset because of a new version.  


Actual results:

Broken, see above.


Expected results:

It should have opened like the normal Google search page, with a white background and text.  When I type in the Google search field, it should show the text I am typing.

I did a refresh.  Firefox -> Help -> Troubleshooting Information -> Give Firefox a Tuneup [Refresh Firefox], and it seemed better.  The default homepage, "about:startpage" shows a Google search box, and it shows the text I type in it, but after that, when you click the search button, it's just blank, a plain white page.

Don't make me go to the dark side and switch to the Chrome browser.

As for the UI & text glitches, this bug seems similiar to Bug 1334533.
As for the title, it is too lame and says nothing specific, please change the title to something more appropriate (you can take the example of a Bug 1334533's title)

Another similiar issue: Bug 1334778.

Another similiar one: Bug 1334830 (it is possible that FF 51+ is visually broken)

I tried Firefox -> Preferences -> Advanced -> General -> Browsing and cleared "Use hardware acceleration when available".  Closed the browser, reopened, still same problem.  Also tried clearing "Use smooth scrolling", still no change.

My Chromium browser has "Use hardware acceleration when available" checked, and it is working okay, so I doubt the problem is hardware acceleration, but I don't know, maybe if that was a big change from the previous version of Firefox, maybe it is.  I'm not saying this to throw the Chromium browser up to you.  I would rather stick with Firefox.

These bugs are related:

https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1627239
https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1659988

In bug 1659988, in the 3rd patch file of /etc/apparmor.d/usr.bin.firefox, if you change the line (70):

   owner /dev/shm/org.chromium.* c,

to

   owner /dev/shm/org.chromium.* rw,

Apply it to /etc/apparmor.d/usr.bin.firefox

Then, sudo apparmor_parser -r /etc/apparmor.d/usr.bin.firefox

it fixes it.

That is, the patch file:

No clue what most of this does, or if it's all necessary, but the line that made the difference (noted above), and the parts about changing python from 3.4 to 3.5, probably helped.

What a waste of weekend.

I'm looking for a job.  Do you want to hire me?

This doesn't appear to be gfx related?

[Dana Keeler (she/her) (use needinfo) [:keeler] (on leave)]

Is this still an issue? The linked ubuntu bug is marked as fixed.

Comment 13

[Linda]

It's fixed.  I think you can mark it as status:resolved, resolution: fixed.  When I try to edit this bug, it doesn't give me the option to mark it as "fixed".

To fix it, see my comment #7 in this thread

https://bugzilla.mozilla.org/show_bug.cgi?id=1334748#c7

or 

https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1659988/comments/5.

Basically, just edit the file "/etc/apparmor.d/usr.bin.firefox" as follows:

Change

   owner /dev/shm/org.chromium.* c,

to

   owner /dev/shm/org.chromium.* rw,

Then, sudo apparmor_parser -r /etc/apparmor.d/usr.bin.firefox
