Firefox for Android Community Forum

I'm using Firefox on my Android phone (model: Samsung Galaxy, Android version 14), and whenever I watch YouTube videos, the playback is choppy and lags every few seconds, even on stable Wi-Fi. This happens on both embedded videos and directly on youtube.com. I've tried clearing cache, updating the app to the latest version, and disabling extensions, but it persists. Videos play smoothly on Chrome. Any fixes?

Hi developers, I'm running Firefox on an Android tablet and ran into an issue. When I enable the desktop version of the browser, accessing websites (like searching on Baidu) fails to load the desktop version. I compared Edge browser with Firefox and found through website UserAgent detection that when Edge runs desktop websites, it switches UserAgent to Linux, while Firefox maintains Android UserAgent for desktop sites. This causes some websites to ignore network requests and load mobile versions. To resolve this, we need to disable and re-enable desktop website access first, which may allow the site to respond to desktop requests.

Can I adjust the settings to switch to the desktop version of the website? I don't want to switch to another browser.

Can't play (listen to youtube) after locking phone anymore. Can't listen to youtube in a different tab anymore. And still can't load comments on videos except youtube shorts

I'm unable to share a link to a webpage via WhatsApp.

Triple dots > Share > select WhatsApp Receive error "Can't send empty message"

Copying to clipboard does work. Sharing with other apps (e.g., Bluesky or Element) does work.

I'm having an issue were any video on firefox i watch automatically pauses. sometimes it takes a few seconds, sometimes instantly.

I've tried restarting firefox and my chromebook, deleting cookies & cache and reinstalling firefox. but nothing helped. It seemed fine for a bit after restarting my chromebook but than it started happening again. Turning off adblock just causes it to pause the ads.

If anyone has an idea of what to do that would be great!

My Firefox browser on Android is very slow. YouTube videos buffer and lag. Pages take a long time to load. Sometimes Firefox freezes or crashes. Please help me fix performance and video playback issues. My phone has limited RAM and storage

For months I've been trying to sync my FF bookmarks between my android phone and my pc and vice-versa. And with no avail. I've looked at so many, many answers and upon trying them with no avail but, frustration. Surely, an extension for droid FF could be developed to freely sync bookmarks between a droid and a pc and from pc to droid.

When I try to upload a file from my mobile device, the file doesn't appear. Uploads from Google Drive are displayed, but I can't select the file. I was able to upload images to this page. What could be the reason?

I'm trying to access a site, I cant use my Google account because I get an error 404 so I need Firefox to not be connected to my Google, I don't know how to change it.

When you leave the app, the page often reloads. This does not occur in Chromium-based browsers (such as Chrome or Brave). And compared to Chromium-based browsers, it's slower and uses more memory, making it difficult to use.

I have read replies to this problem of "no ready to scan button to tap" but find no answer. I'm signed in to the App - there is no "ready to scan " button  ??? Please provide a solution.

Dear Firefox dev team,

I work with web based Redmine tool with has multiple date fields in the issue tracker. Since last FF update the date picker does not let me to "clear" the date field contents.

The date picker and field operation is degrading in FF. A time ago you removed the "X" next to date fields which were super easy to use to clear the fields. So I learned to click, open the date picker and click the "clear" there. Now the clear function is gone too. How is it meant to be used now?

For comparison, here is the google chrome and how looks there with date fields (Vymazat = Clear)

Thank you. Filip

Ever since the recent UI revamp, search does not show suggestions. I confirmed they are enabled in settings. I tried restarting my phone, using other search providers (Google and duck duck go), and stacking trending results, all to no avail.
