As far as browsers go, when visiting my own trusted sites, I don't worry too much about vulnerabilities. Most of the vulnerabilities are also JavaScript-driven, which is optional on my sites. On the server side, of course, I use stuff which is still maintained and sometimes a multi-layer security approach. There is no shortage of both established/mature and still-maintained tech around. Some examples I appreciate: GNU, POSIX, Linux, Perl, SQLite, PHP, Apache, Tcl. For all of these examples there are many accessible resources with oodles of knowledge in many different convenient forms. Newer stuff, where the main resources are Reddit and StackOverflow, and the writing is limited to just a couple of years, is nowhere near as rich or useful. Many newer sites are also heavy and JavaScript-laden, both of which slows down access and skimming speed, if I can access them at all.
