In the latest Nightly - 61.0a1 (2018-04-22) on the Mac - and for at least the last week or so, I’m seeing a couple weird issue with Google Inbox: - Pressing tab to autocomplete email addresses in the to field no longer works - Pressing a keyboard shortcut to format a message (e.g., Command-B for bold) opens up the bookmarks bar instead of bolding I tested these same actions in the latest Production release and everything is fine. If helpful to provide a video of these issues I can.

Add inbox.google.com to blacklist (dom.keyboardevent.keypress.hack.dispatch_non_printable_keys) as workaround.

Confirmed adding inbox.google.com to the specified blacklist fixes the issue. Thanks!

Comment on attachment 8970402 [details] Bug 1456038 - Add inbox.google.com to blacklist of strict keypress dispatching https://reviewboard.mozilla.org/r/238904/#review244896 I think we should just have *.google.com, as I said in some other bug. But sure, we can add still couple of more domains.
