Firefox on Linux currently doesn't support a mixture of HiDPI and non-HiDPI monitors, it has a single DPI setting. I think it will be supported when this [1] bug is resolved.
Shameless plug: I have written an addon to workaround this [2].
I get excited each time I see an attempt to improve the shell, e.g. Mosh [1] and TermKit [2]. I believe that there is room for improvement. But I also think that the UI itself might be in its best form because it is as simple as: type the command, hit enter, get the result. And also equally important, its very efficient.
I don't see that it can replace Bash but it can be useful in some cases. I really liked the Git functionalities.
I was thinking about digital democracy for some time but the open source model loses credibility when you use a centralized approach. I think making it decentralized with a cryptographically sound method is the key. Bitcoin is everywhere. I hope this project gains traction.
