Describe the bug

For a while, I have been faced with a bug involving the Librewolf AppImage. Essentially, when I try to update it using AppImageLauncher, it fails. I have tried downloading the file myself, and it works, so I have been performing manual updates.

Expected behavior

I expected the AppImage to be downloaded and installed.

Steps to reproduce the issue

1. Install an old version of Librewolf as an AppImage (try version 121)
2. Right-click Librewolf in the applications menu and select "Update AppImage"
3. Follow the on-screen instructions
4. The installation should fail at 1%

Have you ever tried to open the details view? Your desktop doesn't really show the UI correctly, but it's a "spoiler" kind of UI element that opens up when clicked and reveals some AppImageUpdate log. If you can open it, please provide the contents (no video needed, just copy-paste the contents into a code tag). If not, you can try to run it from the commandline: /usr/lib/x86_64-linux-gnu/appimagelauncher/update your.AppImage.

Will have to close unless more information is provided by @hellfire103.
