Hi

Not all add-ons are available for Firefox for Android, either because they are unsupported or by choice of the add-on developer.

Hi Not all add-ons are available for Firefox for Android, either because they are unsupported or by choice of the add-on developer.

Hi. I'm certain the add-on is compatible with Nightly for Android. It says on the version history page: Firefox for Android v55 or later (see attachment). Moreover, Yomichan's latest version on the developer's GitHub installs from the XPI file without problems on a Firefox fork based on Firefox v110 (SmartCookieWeb-Preview) and works. Is there any way to see what might be going wrong?

Update: So, I was able to install Yomichan's version on Mozilla's add-on repository (see screenshot) via the infamous workaround everyone uses to bypass Mozilla's babysitting attempts with their add-on walled garden. Basically, I had to:

1. Uninstall Nightly and lose all my user data on Nightly.
2. Track down an ancient, unsupported build of Nightly v68 for Android (before the jump to Fenix, the Firefox overhaul) and install it.
3. Spoof the user agent to a version such that the add-on page says Yomichan is supported and install it.
4. Update Nightly to a recent version.
5. Set up a custom add-on collection that includes Yomichan to re-enable it (Nightly only allows add-ons in the current collection to run).
6. Yomichan appears installed and works as expected.

I can't help but wonder why does the install from the add-on collection fail? Why is it necessary to jump through all these hoops? Anyway, the extension works, so who should I contact to report this?

Now I need to figure out is how to do the same but for the newest version on the author's GitHub. Unfortunately, it seems that it will be impossible since up to date versions of Nightly for Android sternly refuse to let unsigned add-ons run, and the author isn't around anymore to push the latest version to AMO. PS: I tried to install KiYomi too, but it only downloads on v68 and won't install (presumably because it requests Firefox 105 or newer). As much as I hate it, I guess I'll have to continue to use Kiwi Browser for 1 add-on.

You will need to contact the developer of the add-on for support with this.

Thank you for answering. I know contacting the add-on developer is the way to go. Unfortunately, Yomichan's developer has sunsetted the project and won't be pushing updates to AMO, so the second best thing seems to be to install the working XPI file from their repository, which so far is only possible on desktop Firefox. I guess I should mark the solution to the problem, even if it's not ideal.
