Misterious bar wants me to change addon

more options

Today out of the blue, a mysterious bar appeared at the top, telling me that my addon Stylish won't be compatible with next FF, and "here is a replacement", linking me to another similar addon called Stylus.

Who is telling me this and why?

Stylish is getting updated, so it WILL be compatible, and it doesn't seem to be affiliated with Stylus that this bar refereed to as "replacement".

This looks super fishy to me. This bar is lying to me. Does Stylish know that this mysterious message is stealing users away from them and directing them to Stylus? Does Stylus know? If I believed in conspiracies I would ask "did Stylus pay you for this?" but I don't.

I rather believe this is just a faulty design from Mozilla, trying too hard to get people off of outdated addons, regardless if they are about to update or not.

Messages like that were distributed to Firefox users for about a dozen legacy extensions.* The Stylish one was authorized last month, before the November 2 announcement that there would be a WebExtensions version of Stylish. I think it's going to take some time to cancel that campaign.

As for whether the new version of Stylish will be better or worse than Stylus, I guess we'll see. But if you have been using Stylish to modify Firefox's user interface, you'll need to transition those rules to a userChrome.css file. That's probably a discussion for another time.
