Steps to reproduce:

I downloaded a few files and later I tried to remove the last one displayed in the downloads panel.

Actual results:

Even though I selected the last one and clicked "Remove From History", the first one listed was removed.

Expected results:

The entry I selected should get removed.

The Bugbug bot thinks this bug should belong to the 'Firefox::Downloads Panel' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.

I can also reproduce this on Win11 running the latest Nightly build, today's.

Hello I have managed to reproduce the issue only with 99.0a1 (2022-03-07) on Ubuntu 20.04, with the firefox versions 98.0 and 97.0.2 the issue did not reproduce, I have also tried to reproduce on macOS 12 and windows 10 but i didn't manage with firefox 99.0a1(2022-03-07) and 97.0.2.

Marking this issue as new in order for our developers to look more into it.

Any chance you can use mozregression to narrow it down further?

This is pretty bad and we should not ship this.

Are there any concerns in fixing this for 99?
Can this be assigned?

Dao: Do we have an update here? We need to get a patch asap to avoid shipping this in 99.

Reproduced the issue with Firefox 99.0a1 (20220306190604) on Windows 10x64 and Ubuntu 20. The first item is deleted when selecting the Remove from history context menu option on another item.

The issue is verified fixed with Firefox 100.0a1 (20220327213550) and 99.0b9 (20220327183628) from comment 20 on Windows 10x64/ 11x64, macOS 10.15 on Ubuntu 20. Selecting the Remove From History context menu option deletes the expected item from the Download Panel.

All the remaining context menu items were tested and they work as follows:

• Always Open Similar files- automatically open similar downloaded files when checked.
• Show in folder- opens the Explorer with the selected item in focus
• Go to Download Page- opens the webpage from where the item was downloaded.
• Delete- deletes the selected file from the explorer only
• Remove From History- successfully removes the selected item from the download panel
• Clear Preview Panel- clears all download panel
