I experience little breakage with Librewolf, and when I do, maybe 75-85% of the time it is because the site only works with Chromium. I get extensions directly through the browser, I have not enabled anything as far as I am aware. And of course you can configure the cookie clearing. I quite like it, there are (in my case at least) not many exceptions you need to add before it works quite smoothly, but of course that depends on your usage.
