Re: "We decided on a global fallback"
You can contribute to the discusion - in the appropriate place. Bitching on ElReg isnt it.
I would humbly submit that your whine here, (even though you are not interested in changing, so they must be doing something right) is more the reflection of modern society you decry - where you want something for no (apparent) cost, and whinge when you dont have the specific option to suit you personal preferance!
Developers need to make decisions - or change doesn't happen.
Firefox development (and OS in general) isnt some 1970's style collective of comrades developing under a vote for every design line. If it were, you would have truly beautiful code - that could barely render HTML.
