Crash when closing last two tabs in iOS Grid View

NNappingIllusion · 2025-03-08T07:38:02+00:00

What

Tapping the "x" button on last two tabs simultaneously while in Grid View on iOS causes a consistent crash.

How

Open Orion.
Enable Grid View (Settings > Tabs > Tab View Style > Grid).
Create or have two active tabs.
Open Grid Overview.
Press two "x" icons on independent tabs simultaneously.
Both tabs should close, followed by an app crash.

Why

Potentially, the app attempts to switch to non-existent previous tab index and/or default tab.

Additional Details

Safari does not encounter the same issue in their grid overview.
I was unable to replicate the bug in with the Sidebar Tab View Style.
No extensions installed.

Expected Behavior

I would expect the app to not crash.

Desired behavior would follow the same behavior as closing a single last tab.

This should apply to >= 2 tabs being closed simultaneously, as long as they are all of the last remaining tabs.

Im facing similar problem, couldn't find a "always reproducible" case scenario, but definitely having crashes sometimes when closing the last tabs.

and maybe related - sometime the last tab that I close re-opens on its own

NNappingIllusion · 2025-03-08T07:48:33+00:00

I've noticed the last tab re-opening as well occasionally. Planning to file an additional bug in the future when I am able to reproduce the issue and provide a debug log.
