Stupid Enter Key

Why doesn’t the enter key work?
That would be one of the occasional pain points that I have experienced in Firefox. I could never figure out why, only that restarting Firefox is the only way to cure it. Annoying.

Besides the memory issue, this would be the next biggest problem with Firefox. Hence, imagine my delight when I stumbled onto a reproducible way to trigger the issue. Just open two new Firefox windows in quick succession, then close one. The remaining one will have the enter key disabled. I still don’t know why (there’s no errors in the error console). Therefore I have opened a bug about this enter key bug in bugzilla. Hopefully, the powers that be in mozilla, et all can help fix this!
