An AI sidebar doesn't bother me. But it should be an extension, not an inescapable part of the browser.
I'd love to be able to open up an arbitrary web page in this sidebar. It would be super valuable for research. They can obviously do it, since the AI sidebar also loads a web page, but the functionality is locked for some reason, and vertical splitting extensions are pure jank. I really wish Mozilla would focus on addressing some of the numerous user feature requests, rather than whatever the current trend is.
Now that I'm back in my home country, I've gone back to Firefox, which I prefer from a philosophical standpoint. But there's one simple feature keeping me from using it full-time: the ability to rename windows.
My workflow relies on having one window per project. I name the windows Project1, Project2, Project3, and so on, so it is very simple to find each one.
There are a few Firefox extensions that allow renaming windows, but the names disappear every time I restart Firefox, and they don’t sync across devices.
So, unfortunately, I’m back to using Chromium.
