Fenix: IndexOutOfBoundsException java.util.ArrayList mozilla.components.browser.tabstray.TabsAdapter

[liuche]

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.

IndexOutOfBoundsException
Index: 3, Size: 3
Java.util.ArrayList in get at line
mozilla.components.browser.tabstray.TabsAdapter in onBindViewHolder

Seeing this in Release 80.1.2, but not in 81

• Android device: ?
• Fenix version: 80.1.2 Release

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

[DiegoARL38]

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
