Since I stopped using Waterfox, I've been spending time with various browsers, mainly Vivaldi, Firefox, Palemoon and Tor. Palemoon would be fine for me if it were able to work well with more sites, but there are some that don't perform so well with it. For example, there's a site (not the John Hopkins one) that shows charts of my area's coronavirus statistics. Palemoon is unable to handle the chart's complexity and presents a simpler version of it. Palemoon doesn't complain, and I would not know that I was not receiving the optimal presentation if I hadn't seen the same page in other browsers. Vivaldi is a fine browser but occasionally there is a subtle kind of friction in using it. Sometimes searching for a term on SearX will provide no feedback at all, and the browser seems stuck. I've noticed such problems when I'm in a hurry and have many tabs open. This is a fast computer, with 32 GB RAM. The experience on Firefox is somewhat smoother, So I'm going back to that.
There's another issue regarding Vivaldi. I haven't managed to update it to version 3.3 over the past few days under MX, but this isn't something that had me worried.
Chrome is installed too, but I rarely need it.
