can i try this?

[st3fan]

This is a really odd filename ... .../C2dWGyUpaf5+pzHQl49BDQ==.json .. are we sure that is correct? @NotWoods does that Base64 encoded name look correct to you?

[NotWoods]

I think the old Fennec code may hash the filenames

[pocmo]

Looking at Fennec's code it also protects against the manifest not being loadable anymore and then falls back to just launching Fennec. I guess that's the best we can do here too.

[st3fan]

Should this move to the general PWA board? Or is this actionable for the migration?

[pocmo]

Fixed in Fenix. Since this is not really something we can reproduce I'll move this directly to the "Done" column. Locally I did test this by pretending the manifest file does not exist.
