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.
It makes sense here because of bad peering: 8.8.8.8 may be responding in 90 ms right now, but could very well start taking 200 ms a few hours later. So I use multiple services as a backup of sorts.
