Description
Copied from Bugzilla: https://bugzilla.mozilla.org/show_bug.cgi?id=2008078
User Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/143.0.0.0 Safari/537.36
Steps to reproduce:
- Go to Settings -> Customize -> App icon
- Select a different icon from "Default"
- Install and run extension on Firefox Android
web-ext run -t firefox-android ...
Note: Changing the icon back to "Default" restores the correct behavior.
Actual results:
Command failed with the following error:
Error: Activity class {org.mozilla.firefox/org.mozilla.firefox.App} does not exist.
Expected results:
Command should have succeeded and properly ran the extension on Firefox for Android.

This should be fixable by using

Double-check if we don't inadvertently change behavior, e.g. suddenly opening a private tab (or a custom tab).

Unfortunately, that doesn't work.

FYI this issue was originally reported at #2206 (comment) . They then filed an issue on BMO, and then the issue bounced back to the web-ext repo here.
