STR:

I've attached a screen recording testing on a clean profile on Firefox 91. Also able to reproduce on Nightly. Safari and Chrome are able to go back.

Fixed with browser.navigation.requireUserInteraction :)

Huh - didn't know about this pref. Do you have any context on if/how the default will get flipped? I don't see a bug on file to re-enable but it appears Bug 1644914 is the primary blocker from enabling that feature just from reading through Bug 1515073 and Bug 1652452.

I'm also curious if you have a sense of the effort involved with Bug 1644914

I have reproduced this issue using Firefox 131.0a1 on Windows 10 with browser.navigation.requireUserInteraction = false .
I can confirm this issue is fixed, I verified using Firefox 132.0a1 on Win 10 x64, macOS 12 and Ubuntu 22.
