I just meant a vote on browsers. This is the single piece of software we all appear to agree is required.
There isn't much need for that. Pyra may be shipped with whichever browser works well.
AFAIK firefox-esr compiled by debian armhf is slow on pyra, while vivaldi works fine. I personally prefer open-source non-google browser that supports modern web standards ( which may be firefox/falkon/qutebrowser or some other gecko/blink or qt5webengine based browser).
So practically we are left with either compiling a browser that works or use precompiled closed source vivaldi. Another alternative is to use some webkit2gtk based browser ( epiphany/midori/vimb etc.) but that may fail with some sites.
