    I adore Firefox's functionality and the fact that it is open source software that might be created by tens of thousands of people worldwide. You can utilize features that aren't accessible on rival products like Chrome because it is open source.

The 7 best web browsers in 2025
Firefox is a lightweight browser and doesn't require much space or memory, meaning it can operate smoothly even on lean machines. But it doesn't compromise on utility. It's packed with supplementary tools, like a handy PDF editor, a tracker and cookie banner blocker, a read-it-later app, and more. I also like that you can isolate tabs on Firefox so they act in a new,...

UR-Browser Reviews

  1. UR browser behaves like malware--I want to give it zero stars, but this site won't let me...

    Brave is getting heavy, so I decided to try out UR. It kept accessing sites that my antivirus was identifying as unsafe. It wouldn't let me set things the way I like them to be set. It wouldn't let me set up my download manager correctly. In short it was a disaster. Also it wasn't that light. It was about as heavy as my Brave browser, so I gave up and went back to brave.
