Abrowser refuses to install unsigned extensions, even if xpinstall.signatures.required is set to false

Steps to reproduce

  1. Open Abrowser.
  2. Navigate to about:config.
  3. look up xpinstall.signatures.required preference and set it to false.
  4. Try to install an unsigned WebExtension, for example by navigating to Haketilo-1.0-beta2 XPI file.

Expected behavior

Abrowser prompts the user to install the extension. Installation completes after clicking "Add" button.

Experienced behavior

Abrowser shows a message saying "Abrowser has prevented this site from installing an unverified add-on". There's no button to ignore the warning and proceed regardless.

Reproduced on:

Abrowser 96, 97, 98

Notes

LibreWolf adds a

export MOZ_REQUIRE_SIGNING=

line to mozconfig during build. Unsigned add-ons install as expected on LibreWolf. Perhaps the same needs to be done for Abrowser?
