Care to hazard a guess at the number of people at Google working on Chrome or at Microsoft working on Edge?

Last I checked both were bigger than the number Mozilla has working on Firefox.

And yes, the people who were working on Firefox OS are now working on other things, and we _still_ don't have enough people to cover all the things that need doing...

For how long? Sure they have a deal with Yahoo (Verizon?) that could fund them for some time. When that deal runs its course what do they have to bargain with?

Their market share is currently in the single digits on the desktop and they have virtually no market share on mobile which increasingly is more relevant than the desktop in terms of usage.

It's smart for them to decrease costs and maintenance burden right now while they still have the resources.

Desktop usage is still around 15% according to statcounter. They are ~7% across devices.

Firefox for Android has become really good, and I prefer it to Chrome, but my impression is that mobile users are very unlikely to stray from their default browser, even if it is just the blue globe "internet"

well, until those users want to block ads...

I'd like to use them on mobile, mainly because ads are so absolutely obnoxious on there, but their user interface isn't that great and seems to be the one place they haven't copied Chrome.

other things they have put thunderbird and parts of the addon system in maintenance mode. Various other less frequently used browser features have been discontinued too. So there has been some fat-cutting going on for a while now.

pdf.js and B2G cancellation were probably linked in that one justification for a pure JS renderer was to display PDFs on Firefox OS.
