Firefox app on Android is using an insane amount of mobile data that I cannot account for. In the attached image, Firefox used 15GB in a 3 hour span, and I barely used the app during. The only tabs I had open were 5 news articles. I've had this unexplainable high data usage for the past few months. Other internet browsers I've used in the past only used ~3GB per month. This inexplicable data usage makes me very concerned about what Firefox is doing in the background.

Firefox cann't use microphone in my android 5.1 device. But a camera work perfectly (after confirm allow in a pop-up with asking "if you want to share your device’s camera and microphone with that site.") FireFox detect microfone as "default input device" but it doesn"t work. In a special sites that can test a work of the microphone, drop down list of the detected device (in the Firefox) contains only one item "default input device" and microphone doesn't work. In other browsers (Chrome), вesides this "default input device" that drop down also contains other items and microphone work perfectly I need to use microphone in Firefox for web version of a messenger that doesn't support in ohter browsers and apk on this android device

I want to save my settings in DuckDuckGo's Search Engine, which I think means saving the cookie and site data for it, when I quit the Firefox Android app.

Thank you in advance

i dont know if anyone else is having this problem but when using firefox on android the back button gets greyed out and i cant go back it happens randomly and it gets annoying. I hope they find the cause of it and fix it.

Hello,

I'd like to use the History more fully. As it is now, it's impossible to view the full URL for most sites I visit or the time it was visited. FF's Desktop version has a wonderful History. I'd like to see something similar for my phone. Is that possible?

Thanks.

I have an Android S21, and S25. I want to backup tabs, browser history, cache, and cookies to the new S25. I cannot find any way to do that aside from Firefox sync which is NOT what I want.

Does anyone have a good solution? I need to send the S21 back to my cell provider soon

The instructions are to go to Settings in Firefox on the phone and click on Sync and Save Data to scan a QR code on the desktop, but that option is not shown on my phone.

Multiple times a day when switching tabs the entire screen will turn gray and become entirely unresponsive, requiring me to close and restart the app. This has been happening for weeks. It does this regardless of the number of tabs I have open, and continues to do this even after clearing the cache. There is also no report for it in about:crashes.

When the app is going to turn fully grey when opening a new tab when I scroll down and the address bar moves away there is a gray box where it used to be. Also, when opening a new tab the homepage won't appear; there is no "jump back in" or "recently visited" section, just a fully gray background.

I can't reproduce it, but sometimes the URL bar becomes unresponsive. You click on it and nothing appens. I've tried to delete cache and history, but nothing changes.
