Pair Firefox with a fast DNS, and it's noticably faster than Chrome, for the last 3 years or so.
I discovered it accidentally, after switching to local DNS at the office. We run one of the nation-wide ones in a pretty close proximity in network terms.
So I use 8.8.8.8 and 9.9.9.9 in parallel through dnsmasq. Whoever responds the first wins. If you're not stuck in the middle of nowhere, you're probably better off with the latter as it's somewhat more trustworthy than Google.
Instead I increase the directory size to 4K and be done with it.
