Steps to reproduce:

I develop an extension to manage tabs. I've always had this problem when I launch a firefox that was killed for some reason and the "restore session" option appears. This tab is not normal as it will not react normally to user events through my extension. For instance when I trigger an unload it won't show feedback properly like the rest of normal tabs.

What kind of tab is this? I'm wondering how I can adapt my extension to avoid this strange behavior.

Actual results:

Here's a way to reproduce the issue if somebody wants to check:

  1. Install Grasshopper extension : https://addons.mozilla.org/en-US/firefox/addon/grasshopper-urls/

  2. Open firefox with a few tabs normally

  3. Force kill firefox to trigger the restore session prompt. I can do this on linux by using 'xkill' and clicking on the firefox window.

  4. Restart firefox. You should see the restore session prompt as the only tab open. Don't click restore or the other option, just write something like to perform a google search or just open any other url normally.

  5. Open grasshopper's popup or sidebar, and middle click the "x" button that is used to close the tabs in the extension, this is on the right. Or alternatively right click the tab in the extension, click More at the bottom, and click Unload.

Expected results:

Normally when you unload a tab it will show the unloaded icon because the tab emits the signal that it is now unloaded, so my extension catches that. However as you might see with the steps above, the icon is never shown, as if the event is never emitted or something strange happens.

You can try unloading other normal tabs to see how it looks under normal tabs, an icon appears.

This issue can confuse users and might make them think the extension is broken. And it might as well be a bug.

Thanks.

The Bugbug bot thinks this bug should belong to the 'Core::Widget: Gtk' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Component: Untriaged → Widget: Gtk
Product: Firefox → Core

I don't mean the restore session dialog. I mean reusing the tab when you don't restore a session by going to a website manually. The tab remains different from the other tabs.

Component: Widget: Gtk → Session Restore
Product: Core → Firefox

I tried to follow the steps provided, but I'm still not fully sure I understand the issue. Could you share a screen recording showing what happens when you try to unload the tab? Thank you.
