I was developing a webapp for firefoxos (Boot2Gecko) and noticed, that there is no file-picker when clicking on an input(type=file). I came across this bug and it seems as if there hasn't been any movement for some time - luckily, we can at least now detect if its disabled.
But, wasn't boo2gecko/firefoxos supposed to run on the newest Gecko Engine and therefor support everything firefox does on android? I am very surprised about this fact. Is the situation similar with Chromium und ChromeOS that they don't support common web-features of eachother? I am still in shock about this inconsistency! Any insight about this divergence?
