I've removed a bunch of features over the years from Blink/Chromium so I get where they're coming from (and I've written basically the same rationale about the implementation being buggy and unmaintained/not on a path to shipping). That said, while I don't have access to the user research they quote, I do wonder if this move is short sighted in the bigger picture of desktop apps being built with web tech. Given the popularity of Electron and the recent gaming platforms built as PWAs, it seems likely apps will probably start being distributed as desktop PWAs in the near future. With this move Firefox have cut themselves out of the running though so they'll get caught off guard when some big name player releases a popular desktop app through this channel. I can only hope that someone at Mozilla is taking business strategy into account and not only technical complexity.
