It doesn't affect Fx settings -- it just sets a cookie. And I think |
| 53 |
it only affects what happens when viewing youtube.com pages, not |
| 54 |
youtube videos embedded in third-party pages. |
| 55 |
|
| 56 |
The choice really between HTML5 and a Flash plugin, so maybe the button |
| 57 |
doesn't show up if Flash isn't installed. |
| 58 |
|
| 59 |
If you're viewing an HTML5 video, right-clicking anywhere on the video |
| 60 |
brings up the context menu with 'report playback issues', provided |
| 61 |
Firefox's dom.event.contextmenu.enabled is set to 'true', which is the |
| 62 |
default. |
| 63 |
|
| 64 |
Alan, I think Firefox relies on gstreamer for at least some of its |
| 65 |
HTML5 playback capability, so USE="-gstreamer" may be at the root of |
| 66 |
the issue. On the YouTube HTML5 page, do you get a "What does this |
| 67 |
browser support?" section? If so, what does it say? |
