I think the core problem is still tab clutter. Every time I hop onto my iPad to do some light browsing, I have less anxiety. I don't keep many tabs open on mobile/tablet, but I'm already counting 8 opened here as I'm typing on my laptop. Sure, almost everything mentioned in the article is problematic. Then again, maybe it's just us programmed to hit Ctrl-T too much over a decade...
If you have anxiety because your browser has 8 tabs open, you have issues that cannot be solved with computer programs.
