Is this just wontfix, Benjamin? Is anyone working on flash/plugin stuff at this point?

Karl, any comments here? I'm not familiar with Linux keyboard shortcuts.

I get expected behavior with s/step5/step4/ and a build based on m-c 7d2e89fb9233.  Similarly with 55.0b3 and 49.0.2.
I guess it is possible that this only reproduces with some keymaps.
What does "setxkbmap -query" print?

Or an IME may be involved.

Probably the best way to get a clue to the cause of the change is to find a regression window.

Bug 1337781 was my only guess at what may have caused a behavior change, but that went into 54.

Sorry for the delay.  I was waiting on our internal reporter.

It appears that this issue has been resolved as of Firefox 54.0.1.  Please feel free to close it.
