Issue Details

Steps to reproduce:

1. Install Floorp https://floorp.app/en (i used the portable version)
2. Install the extension (not the latest version) : https://gitflic.ru/project/magnolia1234/bpc_uploads/blob/?file=bypass_paywalls_clean-3.9.1.0.xpi&branch=main
3. Try to manually check for Add-ons updates in Floorp. No updates avalaible.
4. Disable Adguard and check for Add-ons updates. The add-on will be updated to the latest version.

Expected Behavior

Add-on should update like it does in Firefox.

Actual Behavior

I'm facing an issue with the updates from extensions NOT coming from AMO (Firefox store). I'm using the add-on called "Bypass Paywalls clean". I'm able to install it but if I check manually for updates in the add-ons settings, Floorp says there's no update available. If I disable Adguard, it updates fine.

Same issue with Librewolf (other Firefox Fork). I had to add it to the filtered apps manually since this browser is not officially supported by Adguard (but it works fine).

Using Firefox, the add-on is updated to the latest version with no issue with Adguard enabled.

Additional Information

Interesting enough, the same behavior occurs on Android (14). Using Firefox or Mull browser, the same add-on updates fine. But using Iceraven (other Firefox fork) it doesn't update with Adguard enabled (at least it didn't a few months back). The smartphone is rooted with the adguard certificate module installed.

Maybe a separate issue should be opened.
