I'm having problems with both Firefox and Chrome. Both are often, but not always, very slow to load websites. With Firefox I get a spinning green circle. With Chrome I get a spinning circle, too. I've no clue what the problem with Chrome is. It can hang and take so long to load a site that I have to close and start over. With Firefox it can be bad but not as bad as Chrome can be.
I don't know but suspect that, with Firefox, there's a lot of media content that causes it to load slowly. E.g., with newssites there are often multiple videos that play automatically and ads.
Any advice on how to address this issue?
