1799302 - Downloading RSS file works like fork bomb, opening a lot of tabs in infinite loop

Status: RESOLVED DUPLICATE of bug 215554

(Firefox :: File Handling, defect)

Description

[pieteekplay]

Attachment: firefox_bug.mp4

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:106.0) Gecko/20100101 Firefox/106.0

Steps to reproduce:

I can reproduce it (every time) by following these steps:

1. Open Firefox
2. Click on a RSS file download link (for example this one https://areweanticheatyet.com/feed.rss) and try to download it.

Actual results:

Firefox downloaded the file, then tried to open it (with Firefox) by opening it in new tab, but then it probably tried to download it again, from local drive and also open it again, opening another tab in infinite loop. To stop this I had to exit Firefox (closing these tabs did nothing).

Expected results:

File should be downloaded and nothing more should happen.
Or it should display some error message, if it couldn't be opened.

I was not able to reproduce this issue on Ubuntu 22.04 and 18.04.3 using the latest Firefox versions. The RSS file from this link https://areweanticheatyet.com/feed.rss was successfully downloaded on my machine(only one file downloaded).
Testing with the link from the steps above in troubleshoot mode could help. You can find more about starting Firefox in Troubleshoot Mode here : https://support.mozilla.org/en-US/kb/diagnose-firefox-issues-using-troubleshoot-mode. Please try with a new profile too: https://support.mozilla.org/en-US/kb/troubleshoot-and-diagnose-firefox-problems#w_6-create-a-new-firefox-profile .
If the bug is still reproducible on your end please report back.
Thank you!

I can confirm that this issue still happens in troubleshoot mode, but it doesn't when I start Firefox with new profile.

Change the default handler in either your OS to not be Firefox, or in Firefox (via Settings > Applications) to not be Firefox, and this problem will stop.
