[BugBot [:suhaib / :marco/ :calixte]]

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.

I think the crash occurred like this.

I take a bookmark from the bookmarks toolbar. Then I go to a folder in the bookmarks toolbar. The folder opens.
Then I go to another folder and then to another one. I hold the bookmark with the mouse the whole time.

After some time, a crash sometimes occurs.

Can you reproduce somehow? If so, can you try to run on terminal with MOZ_LOG="WidgetPopup:5" WAYLAND_DEBUG=1 env variables, reproduce the issue and attach the log here?

For instance run as:

MOZ_LOG="WidgetPopup:5" WAYLAND_DEBUG=1 firefox > log.txt 2>&1

and attach log.txt here.
Thanks.

I would like to add a bookmark from the tab bar to the bookmarks bar. e.g.

Hold a tab with the right mouse button. Drag it onto the arrow symbol on the right in the menu bar.
Now sometimes a crash happens, just like with some folders in the bookmarks bar. I was able to repeat the crash twice.

"Show more bookmarks" in the bookmarks toolbar is sometimes out of the screen. This is the time when crashes often happen.
