Hi Axel

You should be able to get things working again by replacing the 
install.rdf file with a WebExtensions style manifest.json file, which 
includes the key "legacy" set to true.

There's been a mountain of work by a number of people to get things to 
work like they did before, or as close as possible. I have a stack of 
about 6 or 7 patches waiting to land which should make things better in 
a lot of cases. I'm awaiting one final review, so it should be landing 
any day now. Probably best to wait until that happens.
