Firefox for Android Support Forum

Formatted my phone but playing videos still lags and stutters on Firefox browser on my Samsung. Only happens on Firefox, I've tested on Qwant, Duckduckgo and Brave and this problem doesn't occur. What might be the problem and solution?

It's interesting that sometimes the video plays fine until I unmute it. Sometimes the problem goes away after I stop and play or refresh the page. I often have to play the video on a different browser.

So, videos work fine on other browsers so I discart being a phone problem. But on my other phone this problem doesn't happen with firefox.

I've been for several months looking for help/answer/fix for this issue. And I've been with firefox for ever and I don't mind minor bugs and problems but this is starting to be a bit annoying and more and more I feel like I need to move on to a new browser.

Phone: Samsung S21 Ultra SM-G998B/DS Firefox: 127.0.2 (Build #2016028743) Extentions intalled: ublock

Firefox is very dear to me. I use it on my computer all the time for how much more relatively secure it is from other browsers. But Android version is a hellish nightmare. When I open the app, even with no previous tabs on, it will not be responsive for more than 30-45 seconds for seemingly no reason. Same thing when I kill the app and start it again. If it does have open tabs, it will either not be able to fetch their sum number to be displayed on the top right corner until that aforementioned timespan passes, and/or I wont be able to remove/add tabs until again that period of time passes! This is a blocking issue that's been there for well over a year and a half, if not longer!

When I put a video or an image gallery to full screen, the navigation buttons, clock, and status bar don't hide.

They often appear as though they're going to hide, for a split second, but frustratingly bounce right back into view.

On rare occasions, it seems to be random chance, the status bar, clock, and navigation buttons do hide, but I don't know how to get them to hide every time.

I've already tried disabling picture in picture for the app but that has not helped.

What are the reasons the buttons and clock would not hide in full screen? How would we go about fixing things?

Hi,

Progressive web apps do not have the option to install, just "Add to home screen".

For example, https://whatpwacando.today/

Related, it does not support the browser event beforeinstallprompt.

Thanks, Paul
