Wasn't it possible to do some antialiasing for Firefox? So painful to look at these stairs instead of good old lined pages from notebooks. And only two holes in the page which meant to be a spring notebook is kind of lame. And afaik margins and holes for spring are on different sides of a sheet. And of course it looks sooo ugly on vertical ultrawide because of noticeable incline of buttons (on usual monitor they are not) and the insane height of a notebook page.
BTW it will be interesting to see the design of new (also clickable) arrows gathered in stack when this page will contain more links to your works (now it is progressier.com and coronavirus.app and they are not stacking until some third work will appear). So, your daughter has done a great job but you still have some space to grow.
Firefox has always done a spectacularly bad job of thin and especially thin slight-angled gradients. I’m not sure quite why they allow it to remain so bad. I wish they would fix it—but my wish is nowhere near great enough to try to figure out how to fix it myself, which would doubtless be an arduous journey.
Why am I downvoted so heavily? I tested the website in two computers and have payed my attention to any element in dev console, then wrote down all the issues I have found. If I was rude or something, why not just to tell me?
Was it necessary to say "of course it looks sooo ugly" before delivering your feedback? This sort of phrasing isn't constructive, and taints the rest of your message.
When I was younger, I thought it was enough that I was speaking the truth, even if I phrased things harshly. I'd think to myself "they should listen to what I have to say, because I'm correct. If they don't like how I phrased it, that's their problem." Unfortunately, humans aren't robots. If you're going to deliver harsh feedback, it's important to do it in a way where the other person is likely to accept the message you're trying to communicate. Otherwise, you may as well have not sent any message at all.
The community guidelines are a pretty good start. If I were to take a guess, your comment came off as more of a complaint than constructive feedback. Your point may have been valid, but the delivery was just “off”.
