Firefox 61

WebGL doesn't work on intel driver, but if I run firefox with optirun — it works. Also WebGL in Chrome works on Intel too.

This is caused by a change in the lastest Mesa's that Manjaro ships. Mesa tries to access parts of the filesystem it should have no business with and the Firefox sandbox blocks it.

Mesa Bug: https://bugs.freedesktop.org/show_bug.cgi?id=107516

Firefox Bug (with workaround): https://bugzilla.mozilla.org/show_bug.cgi?id=1480755

Updating Firefox to 62 solves this, as does updating Mesa (libdrm) to an even more recent version - the issue has been fixed on both sides. If you can't update Mesa or Firefox, apply the workaround in the bug, but don't forget to remove it when Firefox 62 is released.

Are there any messages in the Graphics section on the "Help -> Troubleshooting Information" (about:support) page related to WebGL ?

Yes, there are. Sorry for my initial wrong answer, I dudn't understand your question and thought you're talking about error messages. I can't see error messages, but can see lots of information about Web GL.

The screenshot you posted seems to indicate that WebGL should be working properly as I'm not seeing any errors reported.
