Browsing a large code repository. The scrollbar highlights allow me to "eyeball" the page and go to the general locations quickly rather than hitting Next a thousand times (which feels primitive as hell anyway), especially when a block of code has the same keyword used many times and I need to move on to the next block.
I tried Firefox for a while but I rely on that feature around once or twice a day and I preferred using Chrome for those browsing sessions. So I dumped Firefox and switched back.
Ah, I think I just avoid using a browser to browse a code repository. Swiper/helm in emacs are far superior for searching a repository. Unless I am looking at more than what I can checkout locally... which, I typically don't need to do.
