Firefox mpo na Android Community Forum

For the past two weeks, I haven’t been able to access youtube.com on Firefox. Every other browser loads it without any issues. I’ve already tried switching devices, reinstalling Firefox, changing networks and locations—but nothing fixes it. The YouTube app works fine, and this problem only occurs when opening youtube.com in Firefox.

On desktop Firefox, I get:

Secure Connection Failed An error occurred during a connection to youtube.com. PR_END_OF_FILE_ERROR

On mobile Firefox, I get:

Cannot Complete Request Additional information about this problem or error is currently unavailable.

I would appreciate any help resolving this issue.

A site I use, bestcrosswords.com, has been acting weirdly since late on 11/18. Instead of the highlighting changing with the active word, the highlighting has gone completely haywire. I have already posted regarding that and filed a bug report (the problem does not occur in DuckDuckGo), but the site has started giving a suggestion I cannot follow.

Please see the image. I can see how the suggestion works on a desktop, but not a phone. Please forgive me if it's considered too obvious to document, but despite searching the phone's software and the Web for advice, I cannot find anyway to follow the site's suggestion.

Could someone clarify the point for me?

Thank you.

This is all on my Android phone but I use the Stash app for investing here https://www.stash.com/ but the Google SSO button redirects me to https://accounts.google.com/gsi/transform with a blank screen and nothing happens. If I instead open the webview in Firefox as part of the browser app, then Google SSO works fine for me. Since it works in Firefox as a browser it seems to me this must be a bug in Firefox when in a webview. Any idea what's going on?

Hi,

I’ve noticed that Firefox on my Android phone becomes noticeably slow whenever I open certain video or streaming pages. The browser doesn’t crash, but the page takes a long time to respond, and scrolling becomes choppy until the video fully loads.

I’ve tried clearing the cache, disabling add-ons, and testing on both Wi-Fi and mobile data. The issue only seems to happen on Firefox — the same sites load smoothly on other browsers.

Is this a known performance limitation, or is there something in the settings I should adjust? I’m not sure if it’s related to media decoding or just heavy websites.

Thanks for any guidance.

Like most crossword sites, only the active word is supposed to be highlighted. Starting late on 11/19, the highlighting has gone haywire. I have attached an image.

Maybe it deselects when the focus shifts, maybe it doesn't. Maybe it shows which square is active, maybe it doesn't. Eventually, I back up a page and then return, which clears the highlighting but not the words.

I've tried actually quitting Firefox and restarting, but it didn't help.

Thank you for any help!

When I click on YouTube comments to read them Firefox mobile pops up a blank window. Works fine if I switch to desktop mode. Android Version 16. Tried reinstalling Firefox. Cleared cache and cookies. Nothing so far has worked.

Hi!

I have some problems with Firefox on Android.

I often visit the Swedish public service news site "www.svt.se/nyheter".

Sometimes some videos won't play, but if I open the same page in Chrome, playback starts as it should. One example is the video in this article:

https://www.svt.se/nyheter/lokalt/smaland/over-400-kvadratmeter-parkslide-ska-bort-vaxjo-testar-ny-metod

A general problem is that I almost always have to reload the tab, to be able to watch the video, when I open an article in a new tab. The first time I press play, the video freezes. The sound plays but the image becomes static and pixelated, often in shades of green. One example is this article:

https://www.svt.se/nyheter/lokalt/stockholm/uppgifter-sjukdomsfall-bakom-bussolyckan-i-stockholm

I have a Google Pixel 5 with Android 14 and Firefox version 145.0 (but the problem has existed in previous versions).

Thanks in advance!

I have a few web pages on my local network that are behind basic HTTP authentication. If I try to navigate to any of these sites in Firefox for Android, I get the popup to enter my credentials, but after entering my credentials, the page just never loads. The loading indicator just stays in place.

I do get a 401 unauthorized if I don't enter correct credentials, but with the correct credentials entered the page juat never loads.

I've tried clearing site data, disabling extensions, and disabling protection features like tracking protection and dns protection, but none of that resolves the issue.

I also tried Firefox Foxus to see if my particular installation is borked somehow, but Firefox Focus has the same issue.

A different mobile browser though, such as Brave, loads the page just fine after my credentials are entered. Works just fine in Firefox desktop as well.

Is basic HTTP authentication just broken in Firefox for Android? Are there any other workarounds I can try?

(My phone is a Galaxy S24)

so whenever I try logging into PlayStation using Firefox, it gives me some kind of server error. But when I try logging in with chrome for example everything's fine. (Android)

Since the November 6th update, my input from SwiftKey keyboard specifically on Duckduckgo site (not when searching from Firefox address bar) is being very disrupted. Single click on spacebar is ignored and autocomplet filles in a different spot than the cursor. This doesn't happen an any other website an also does not happen on chrome for android on Duckduckgo. Also this does not happen with gboard in Firefox. Any ideas?

My Android 11 Lenovo 10" tablet will not display the desktop version of any site, despite having both menu switches set to DT. It's particularly annoying on sites like Wikipedia where I am registered and have configured the WikiP user settings for a style that has worked for me for 15 years. The two views are switchable in Chrome, but suddenly Firefox is only displaying the mobile page. I am trying to migrate to primarily using Firefox to escape the big G marketing artillery barrage and totally overreaching information piracy framework. Any suggestions out there? I wonder if Android itself could be responsible?

I cant even see Chewy's page. Just stays white. They told me they no longer allow Firefox to access their website. They told me to use Chrome or Edge. Obv they want more personal data.

I have Proton VPN (i tried different servers and even disconnected). I run several blocking extensions incl User Agent Switcher. I tried a Chrome or IE string. Still cant even see the website.

I really dont want to give them more data. I've had no problems for years. Anyone else? Thanks.

Why MSN pages are not shown? I tried all suggestions on the web with no results. Instead of showing the MSN pages for the selected topic it always shows the main site page.

ANDROID 15, FF 144.0.2 When I load any YouTube video from the FF Browser, and click on "Comments", they DO NOT APPEAR! (See attached screenshot). Even though the page states there are a number to view, e.g. 30. This problem started a few months ago, and continues, even after recently updating to 144.0.2. The problem does NOT EXIST with other browsers, e g. DuckDuckGo and Chrome (see screenshots). Nor obviously if I choose to "Open in YouTube ". But if I choose "Cancel", meaning to open the page with the FF Browser, that's when the Comments become INACCESSIBLE. PLEASE HELP!!

Hello Mozilla team, 👋 I’ve noticed that some educational websites — including my own scholarship guide, https://theoasisscholarship.com/

— aren’t displaying correctly on Firefox for Android.

The issue I see: Some pages don’t load fully, especially forms and PDF links. The same pages work fine on Chrome or Edge mobile. Clearing cache or disabling add-ons didn’t help. Can you please guide me on how to debug or fix this issue? Is there a specific setting, user agent, or cache issue on Firefox mobile that may cause this? Thank you for your help! 🙏

Hello everyone! I have a slight issue with the website https://anime-bit.ru/ in Firefox on Android. When scrolling down the page, it doesn't load further, and images don't appear. It works fine in Firefox on desktop and in Chrome on Android. I'm not sure whether the problem is with the website or the browser.

I’m attaching a video demonstration of the issue. Would appreciate your confirmation or any suggestions!

Hi everyone, I manage a website called, which lists the latest mobile phone prices and SIM offers in Bangladesh. The site looks perfect in Chrome and Safari on mobile, but in Firefox for Android, some sections (especially the comparison tables and menus) don’t align correctly. I’m using the Kadence theme with responsive CSS grids. Are there any known Firefox-specific quirks with flexbox or grid layouts that could cause alignment issues on Android devices? Also, what’s the best way to test and debug responsive layouts directly in Firefox Developer Tools for mobile views? Any insights or debugging tips would really help. Thanks in advance!

Hello, When I submit a payment for my driver's license on my state's website site, it always tells me that an error has occurred and to try again. I have retried it for 6 times with the same result. The web site states that I should be using version 38 of Firefox or higher but I don't know how to check for this. When I go into about Firefox there is just a long string of numbers 144.0.1 that continues from here. Is this version 144.0.1 higher than ver 38? Thank you in advance for your reply.
