Performance on low-end Android and YouTube Portrait Fullscreen feature

This browser is slow in browsing compared to the Chromium engine on low-end Android devices. Also, this browser doesn't have a special YouTube feature to "swipe from the top" (swipe down) to see the video in Portrait Fullscreen mode (one video in fullscreen in portrait mode, not landscape). This removes the video suggestions shown below the main video to maintain high focus on the current video. Brave has this feature; that's why I use the Brave browser to replace YouTube Premium. And I use Firefox with uBlock Origin to remove all ads from Facebook only. So in short, I use Firefox to browse Facebook and I use the Brave browser to watch YouTube. (You might wonder why I don't use Brave to browse Facebook? Brave's built-in ad blocker is weaker than uBlock Origin, which can't remove all Facebook ads even in aggressive mode. That's why I use Firefox for Facebook). But I want everything in Firefox Android. Please focus on popular platforms like Facebook and YouTube, so that people think that we don't need to buy Premium; we can use Firefox with the uBlock Origin extension without buying Premium for removing ads.

Hi,

The people who answer questions here, for the most part, are other users volunteering their time (like me), not Mozilla employees or developers. When a Mozilla employee jumps into a discussion, you'll see the Mozilla Staff label next to their name.

If you wish, you can leave feedback for developers on the Mozilla Connect website. Click the Firefox Menu Fx89menuButton button in the toolbar, click Help and select Share ideas and feedback…. Alternatively, you can use this link. Your feedback is collected by a team that reads it and gathers data on the most common issues.

You can also file a bug report or feature request. See File a bug report or feature request for Mozilla products for details.
