OK, you listed the top 5, but how about the lesser known browsers. I use 2 that are built on Mozilla (like firefox) called SeaMonkey and CometBird and both have all the ‘stuff’ that FF has & so far all of the addons work. BUT, these are both Chrome fast.
I had a great Tosh PC and the power supply fried, so I have a Dell that I bought in Y2K. Old PC can’t take the new browsers so I had to search and I am really happy with the results. I assume that you can find both by Googling their names.
