I'm well aware of what Vivaldi can do but I refuse to support Chromium's monopoly. In fact, it's the only reason why I use FF.

Firefox is open source and not chromium tho. Using Chromium still helps Google push their standard as the web standard. Firefox and Safari are the only two pillars standing up against Chromium we have now.

Vivaldi is pretty cool... Although most features I don't need. I have a hard time breaking up with Firefox.

I was using Vivaldi as my living room TV PC browser because it was kind of a one stop shop.

Eventually I found plugins and mods for Firefox that did only what I need.

RSS feed sounds pretty amazing. What site can it read?
