Brave browser: EditThisCookie randomly uninstalled

[mcgroarty]

Note: I've created the same issue in the Brave forums. Perhaps between there and here, it will be possible to solve this.

Description of the issue:

Brave desktop periodically removes the EditThisCookie extension without warning

How can this issue be reproduced?

• Install EditThisCookie Chrome extension https://chrome.google.com/webstore/detail/editthiscookie/fngmhnnpilhplaeedifhccceomclgfbg
• Pin the extension so you can see that it’s present
• Wait a few days
• Observe: The extension is randomly removed - uninstalled, not just unpinned
• Observe: If the extension is reinstalled, it returns to the pinned position. Brave remembers what position it was in.

Expected result:
Expected: Extension remains in place

Brave Version
Version 1.57.53 Chromium: 116.0.5845.114 (Official Build) (x86_64)

Additional Information:

This happens on Mac, Windows, and Linux. Sync is enabled on the profiles, if this makes a difference.

This isn’t a recent regression, it’s been happening for an unknown amount of time. Every month or two I go to use the extension and find it missing.

The issue happens across multiple browser profiles. i.e., I have multiple Brave browser profiles for work, personal, games, etc.
