YouTube videos cannot be played in 4K resolution on Firefox; the maximum supported resolution is 1080p. However, when using Chrome browser, 4K playback is supported.

Every time I'm trying to stream video like live sports the video lags so much. I've tried to reinstall the app and run it with no addon ( even though I only use 2 addons) and problem still persists... I'm using a Samsung S21 Ultra.

Just updated Firefox, now it doesn't respond to clicks, not can I select text, websites don't load, all the tabs are at half -resolution. Unusable. Need to use it.

I'm giving up trying to add the mobile app to Android. No one offered any solution and only asks the same questions that I've addressed myself, so I'm done and will just use Chrome and Yahoo..

Hi, When I am on a site for instance to upload my resume for a job listing when I click on upload a file it doesn't do anything. It doesn't matter what site I am on it's the same everywhere. I then go to Chrome and use the same site and it works. It brings up the location I want to choose for the file.

I have tried adding permissions and it still doesn't work. I have build 125.0 My question is there a way for me to choose where the location is of my files? Like on my phone or SD card? I have looked and I don't see that for Android version. Thank you.

Websites are mostly reporting that my browser Firefox Android latest needs advanced or enhanced Javascript support and about:config no longer works.

All sites working in Microsoft Edge for Android.

Hello, everyone!

I'm encountering a perplexing problem with downloading .mobileconfig WiFi profile files through a direct link in my ReactJS web application. This functionality works flawlessly on Google Chrome, Safari, and Edge across iPhone and iPad devices. However, when attempting the same on Firefox for iOS, the downloaded file becomes corrupted and unrecognizable as a .mobileconfig file.

The download mechanism is implemented using a simple anchor tag that points directly to the file on the server. Interestingly, only in Firefox on iOS, the content of the .mobileconfig file gets altered during the download process, leading to corruption.

I'm keen to understand why this issue is occurring specifically with Firefox on iOS and how to resolve it. Has anyone else faced a similar challenge or have any insights on how to ensure the file downloads correctly on all browsers, including Firefox on iOS? Any advice or suggestions would be greatly appreciated!

Thank you in advance for your help!

Firefox for iOS no longer will open when I click from my mail or the QR scanner. This is a recent development. To be precise, Firefox opens, but nothing else happens! Any suggestions? Thanks.

i’m not sure how to explain this. on only one site (arstechnica.com) the page displays odd coloring and freezes if sorted by votes, and as of today, if selecting the next page. it’s truly bizarre. other browsers don’t do this, only ff. i prefer ff though and would appreciate your help, thank you.

Decided to check my passwords for something because I forgot it. List was completely empty.. Search bar not working (tried just in case), When using saved passwords autofill out of Firefox app it said 'you have no saved passwords with firefox' or something similar I'm on an android phone right now. Can't currently check if they are also gone on laptop.

Don't know what to do. Other posts were not helpful

When firefox updated all of a sudden when I go to youtube sound will not play. My music has sound, when I go to chrome and safari youtube has sound. I have done everything in your help section (Not blocking - allowing audio on all websites etc), clearing cache and cookies and restarting - still no audio

When I scroll some pages in Firefox mobile, there are some graphic artifacts and glitches, especially when elements are moving. I tried this site on different browser (chrome), there are no problems.

After I want to multitask on my phone and switch between the browser and other app. The page becomes blank and refresh button doesn't work.

I need to open a new card to continue using the website loosing all temporary changes made to it.

Issue was present for at least 6 months.

The upload photo button does nothing... on this page, on Reddit, Facebook too. I've tried clearing cache. I'm on latest android and firefox 124.2.0. I have standard security enabled and permission is set to "Ask" for camera and storage. How do I make this work again?
