I recently discovered that watching a video by phone on Rumble has different features depending on your browser. For example, with Chrome, if I switch to a different window or even a different tab, Rumble stops playing altogether. But on Firefox, Rumble continues playing in the background, which is great if you get a text or email while watching a video. Duck-Duck-Go didn't allow background playing either.

This isn't meant to be a which-browser-is-better post, but merely a tip about using Rumble. I'm on android, fwiw. If anybody else has good tips, please add your comments.
