Well I got tired of waiting for new browser and my script to be added into the system.
So I decided to make my own based upon pure Chrome instead, so if anyone is interested, you can download it and install it from:
browser.chrome.59.0.3071.115-1.zip
Chrome version: 59.0.3071.115-1
- includes Adobe Flash plugin 26.0.0.137 (and of course widevine).
- hacked away pulseaudio compatibility because chrome does not accept ALSA when pulseaudio for bluetooth is running in background in LibreElec.
I do not guarantee maintaining of the package, but at least it works stable and don't crash the entire browser entering some random flash content.
Feel free to go through the code, it's mainly a fork from LibreElec but includes libraries needed for Chrome and Chrome itself incl. Adobe Flash plugin. So note that you'll be accepting all licenses and stuff by installing this package automatically. Also you install this on your own risk.
