Ghostery 5.4.1 can't be installed on Firefox for Android > 29

Edit Subject

My point was that it can't be installed from https://addons.mozilla.org/en-US/fire... -- it has to be installed from https://addons.mozilla.org/en-US/fire... (if you're aware of it), or you can of course install one of the clumsy and largely unsupported User-Agent modifying add-ons... which no one should have to.

The install button on AMO is disabled for incompatible Firefox releases if the developer doesn't update the maxVersion string at least once in a while. Which it hasn't been in... what, nine months?

It shouldn't make a difference which AMO page you start from, although my link is for the Android page, while yours are for the Desktop page. Try following Mozilla's official instructions:

• https://support.mozilla.org/kb/find-a...

Mozilla switched to "compatible by default" quite some time ago, so maxVersion is no longer relevant. Browsing through AMO's "most popular" Android Add-ons, I see many of them have maxVersion lower than 33 — so this would not be a Ghostery-specific issue.

Whatever is going on probably has something to do with your specific configuration and, so far, doesn't appear to affect anybody else. If there really was a problem, and it was what you claimed it to be, (1) I'd expect a lot more people to be reporting it (2) it would be easily reproducible. They aren't, and it isn't. I also checked support.mozilla.org, and the only related questions were from people who had been trying to install extensions that weren't marked as compatible with Android (which doesn't apply in this case) or had screwed with their User-Agent or other about:config settings.
