Local browser analysis

@Doofenshmirtz I wasn't giving you a lecture, just defending my choice of a web browser which you called "weird" only because (apparently) you haven't heard of it. I will not carry this subject further because it's getting off-topic for a support thread on a chess website. But thank you for generously granting me the right to choose whichever software I find fitting for my needs.

While I agree with the above OS concerns, as a previous Vivaldi user eventually I switched to www.palemoon.org/ which I think can still run on older OSs (although officially Lichess doesn't support it).
