May already be fixed by 81, but filing to keep track of here. Maybe the bump in numbers is due to Migration.

A handful of crashes on Release.

Device: Xiaomi Redmi Note 8 Additional information: TalkBack is enabled.

Sorry for the formatting, I'm on mobile and with TalkBack on

[BlindMoon38]

The tabs tray is unusable, the only way to change tabs is via the gesture on the toolbar, and closing them requires deleting browsing data.

Probably related to "Additional information: TalkBack is enabled"

We should try to get a fix in because the tabs tray is unusable for TalkBack users

[ekager]

Can repro crash with TalkBack on
