974049 - Failure to initialize 3-D view freezes page elements and scroll on tab

Status: RESOLVED WONTFIX

(Firefox Graveyard :: Developer Tools: 3D View, defect)

Description

[Landpaddle]

User Agent: Mozilla/5.0 (Windows NT 5.1; rv:30.0) Gecko/20100101 Firefox/30.0 (Beta/Release)
Build ID: 20140218030202

Steps to reproduce:

1) Have a graphics card which does not support 3-D view.
2) Navigate to any web page.
3) Attempt to initialize 3-D view via the developer tools button.
4) Try to scroll and click elements.
5) Navigate to another URL via the URL bar.
6) Try to scroll and click elements.
7) Repeat.


Actual results:

All page elements become static on that tab.  Scrolling does not function.


Expected results:

Failure to initialize 3-D View should fail more gracefully, that is, without effectively freezing that tab.

Could you please try the following, to see if you still reproduce the issue:

1) running in Safe mode:

2) try this with a clean profile:

Trying both steps, the issue is reproducible.

Comment 3

[Landpaddle]

The issue is also reproducible on Vista and Win7, x32 and x32_64, but since I cannot add platform tags for all three, just listing it as 'all'.

If WebGL isn't available, you shouldn't be able to open the 3D view at all, nor even see the "cube" button in the toolbox. Can you please let me know

* Is webgl.force-enabled true in about:preferences ?
* What does http://get.webgl.org/ say?

I mean about:config, not about:preferences

By default, webgl.force-enabled is false. Tilt activates correctly after enabling the preference.

With the preference disabled, http://get.webgl.org/ says 'Hmm. While your browser seems to support WebGL, it is disabled or unavailable. If possible, please ensure that you are running the latest drivers for your video card.'

With the preference enabled, http://get.webgl.org/ says 'Your browser supports WebGL'

The issue with the tab-freeze persists to the latest Nightly.

The 3D View has been removed in Firefox 47. Closing all bugs inside that component as the component will be moved to Firefox Graveyard.
