What issue do you have?

Although my Ubuntu 24.04 is set to use Firefox as the default browser, when opening a link within Joplin, it uses Brave instead. Is there any setting I need to modify?
From what I've researched, it seems that Joplin cannot execute correctly due to an issue with the chrome-sandbox permission restrictions. When it opens, it lacks the necessary permissions for chrome-sandbox to run properly (this appears to be a common problem with Electron applications run from AppImage), which may lead Joplin to bypass the default browser setting and open another installed browser instead.
I have found mentions of different issues related to this AppImage/Electron restriction in the blog in the past, but I have been unable to resolve this particular problem of using Firefox within Joplin. Can anyone help me if they have found/fixed the same problem?

Change your desktop environment's default browser, then revert it to Firefox. Then, confirm that all browser's settings show that they aren't the default browser. Then, click Make default in Firefox settings.

If that doesn't work, try these fixes:

Set BROWSER environment variable to firefox
Choose Firefox to replace the default application of MIME types set to Brave
