Browsers for old PCs

[TheDead]

I will however suggest that one thing I've seen make a difference in browser behaviour generally - regardless of available RAM - is adblocking because so many websites now run tarpits full of ad related Javascript on every page.

So true! I forgot to mention I ALWAYS install uBlock Origin from Raymond Hill (Gorhill). Don't worry Jerry, I whitelisted Linux Lite sites.
For Palemoon though, you have to search for the Legacy version, which can be hard to do.
2G is quite minimum for multi-page browsing. With the current Firefox, you NEED an adblocker yes. Note : uBlock Origin is available in the standard Firefox Extension "store".
