1246303 - webgl broken firefox 44, ubuntu

Status: UNCONFIRMED

(Core :: Graphics: CanvasWebGL, defect, P3)

Description

[brendan c]

Was working as of Jan 24, the last time I used a webgl enabled website (onshape.com). Today (since upgrade to 44.0) the site complains that my browser doesn't support webgl. Tried some chrome experiments, they also say my browser doesn't support webgl. These sites continue to work fine with Chromium.

Tried setting webgl.force-enable=true (per advice on internets), no luck.

Here is my environment info from about:healthreport

Please check if the same happens with http://archive.mozilla.org/pub/firefox/releases/44.0/linux-x86_64/en-US/firefox-44.0.tar.bz2 (make sure you test with a new profile to eliminate modifications as a potential cause). If it does not reproduce with this build then this is a bug in Ubuntu's version and needs to be escalated to Canonical.

If it does happen with the official mozilla build. Then finding a regression window using mozregression (http://mozilla.github.io/mozregression/) would be very valuable.

Since I filed this bug, my build has moved on to:
      "buildId": "20160209234513",
      "version": "44.0.2"
and whatever the problem was, it seems to have stopped...

Thanks for the help!

Curiously, this same error has reappeared since upgrading to 45 from 44.0.2

I reiterate comment 2. If this happens in an official Mozilla build (not the version Ubuntu packages) then please use Mozregression to find the regression window. Thank you.
