I verified this is a blob that we're trying to download, so it should be blocked by https://bugzilla.mozilla.org/show_bug.cgi?id=1501735.

We have blob download support now, but this still fails due to a security issue. Filed in GV:

Looks like this works now with latest Privacy Badger as the download is now a JSON file. @AndiAJ can you verify when you get a chance, thanks! :)

Hi @csadilek , I've just checked this matter on the latest Nightly 201124 using the following devices:
• Google Pixel 3a (Android 11)
• Huawei Mate 20 Lite (Android 10)
• OnePlus A3 (Android 6.0.1)

✔️ The user data is properly exported from: Add-ons Manager → Settings → Manage Data → Export user data
❌ On the other hand, it doesn't work when trying to export them VIA the Privacy Badger dashboard.
⋮ Main menu → Add-ons → Tap on Privacy Badger → Select the upper right Gear Icon→ Manage Data → Export user data

✅ Checked on Fennec as well, and the user can export their data from there as well.

Please review and share your thoughts. ☺️

Thanks, @AndiAJ for catching this. The remaining case is a different issue. The options UI / settings page should be opened in a tab, but clicking on the gear icon opens it directly in the browser action popup where we don't have support for downloads.
