As of 7/10/2025, Xfinity Streaming does not open through Firefox. I much prefer Firefox to any other browser so I am a little mystified as to why all of a sudden Xfinity Streaming does not open. I receive my Comcast email through FireFox but when it comes to streaming content, the Xfinity logo just sits there and does not open.

Google Meet repeatedly drops and rejoins calls with "you have lost your internet connection" error. It's been happening consistently over the past few weeks. I have zero issues if I join the same calls with Google Chrome. I've tried updating to latest, restarting Firefox, restarting my machine, but it still happens.

Over the past 2-3 months, Outlook, when opened on Firefox, continuously signs me out and forces me to sign in whenever I leave it open for more than a few minutes. Some days this occurs 5 or 6 times and has become very annoying. Even when I choose 'trust this device', or 'keep me signed in', or 'don't ask again for 30 days', it just automatically signs me out. I use 1 desktop and 1 laptop and this problem exists on both.

Also: I have a default font chosen for email composition that the system all of a sudden seemed to not recognize. I can select all content in an email and change it to my default font but it doesn't use it automatically. It either uses Segoe or Calibri depending on which computer I'm using. I have one laptop & 1 desktop. Oddly, if I place my curser down at my signature, which is formatted with my preferred font, the system will then use the correct font. As I'm typing, if I need to correct something, after doing so and trying to type the next word, it refuses to put a space between the where the curser is and the first letter of the next word. I literally have to start a new line by using the enter/return key, type the next word, then use backspace to take it back up to the previous line where it belongs. These are both small details but drive me batty!

I checked with my IT dept and they had me do a test drive on Chrome, which I NEVER use. Sadly, none of these issues exist in that browser, so for the time being I'm forced to use Chrome if I want to avoid the constant need to sign in and the other irritating malfunctions.

Anything you can point to or settings I can change to fix these issues?? Appreciate your assistance! Kayla Bates

Since a recent update, whenever I try to go to ufc.om, Firefox shows me the error in the attached image. It used to display ufc.com without issues before the update [ don't remember which update ].

Other browsers [ Chrome and Edge ] display ufc.com without issues.

When pasting an image from the clipboard in Outlook Web Access in Edge there's right mouse button option to "Paste as Image". This places the image inline. In Firefox there's no option like this.

Safe mode (troubleshooting mode) doesn't fix this. Ctrl + V or Shift + Ctrl + V doesn't fix it. Shift RMB to get Firefox menu does show Paste and Paste without formatting but it doesn't paste any inline image.

I've attached a screenshot of Edge and Firefox with the Outlook context menu and Firefox context menu.

Firefox version: 140.0.4 (64-bit) Edge version: 138.0.3351.83 (Official build) (64-bit)

I updated my MAC OS, my Firefox IS up to date. My RING website Log-In no longer works on Firefox, yet is DOES work using Safari, which I never use. Is there a setting on the latest Firefox I can change so I can access my RIng account from my Desktop browser? It DID work last month

Recently, after the newest Windows 11 update, Twitch hasn't been loading correctly, the tab looks as if it finished loading, but the page gets stuck in endless loading, no other site has this problem, and it happens even opening links to Twitch channels directly. I've added and screenshot of the problem.

I'd love some help or at least know if this is a problem on Twitches end or not. Thanks.

Kind of a combination 'Browse/Download problem. This morning on rising, 07/11/25, Claude.ai's html artifacts quit loading on Firefox. Doesn't matter whether I'm on laptop Macbook Pro or iMac...or iPhone...but it loads in Safari and Google Chrome? Site is fine...document artifacts are fine...but html sits with spinning wheel?

I have loaded Messenger onto my new computer as well as Firefox. When I go to Messenger the Voice and Video icons at the top right are greyed and when hovering over the icons, I get a message that video calling etc is not supported. i had no trouble on my other computer but am not sure how to activate the video and voice options. Can you please help me solve this issue. Thank you

Hi,

Whenever I try to watch videos on Anime Slayer APK in Firefox, I get a message saying the browser is “unsupported” or the video just won’t play. I’m using the latest version of Firefox on Windows, and I’ve already cleared my cache and disabled extensions, but the issue persists.

Interestingly, the same videos work fine in Chrome and Edge — so it seems like a Firefox-specific problem.

Is there some setting or add-on I need to enable to make it work? Or is this a known compatibility issue with certain websites?

Thanks for any help you can provide — I’d rather not switch browsers if I can avoid it.

Hello support-type people,

I have a specific website that I have active in FireFox called myNoise.net. It allows me to generate background noise generators to cover-up the distracting noises from my neighbours when working at home on my desktop computer. The audio on the website worked the last time I opened Firefox ~2 July ... but today, when I opened the browser, the audio no longer works. I cannot get the website audio to load at all - I added the website to additional exception lists & shut down some content blocking extensions, but no joy. The website was already listed in multiple exception lists & I do not know or understand what change(s) occurred with the browser that would prevent this site from properly functioning - since it literally worked a week ago. I would appreciate any assistance and/or guidance with this issue, otherwise I will be eliminating Firefox as one of my browser options. I have provided a screenshot of the site that shows the perpetual "now loading" screen. Thank you.

In <style> I have td {padding:.5ch;border:solid, grey, thin; text-align:center} Suddenly the borders stopped working, but still work in other Browsers. I added <thead> to the table and thead {display: table-header-group;} in the @media print in the style section, but removing them doedn't

Attempting to bill pay at Allstate page, stating the browser is not compatible. What options do I have? I have been using Firefox for > than twenty years, I have a hard time trusting anything that comes from Microsoft after their internet explorer debacle .

When using excel for office 365 there's a behavior unique to firefox. Normally when a cell is selected Ctrl+A will select all of the contents of the cell, this is normal behavior. When overwriting the text by typing any other text it will begin typing in a different orientation, (between horizontally and vertically). If pressing Ctrl+A again and typing any text it will again flip the orientation. This is infinitely repeatable on all systems I've tried. I've complained to microsoft support to a near-harassment level and they've told me to talk to you. I'm not making a bugzilla account so I'm posting it here.

Cheers, Toxic

I have a problem that I cannot resolve for months. I'm always listening to YouTube I'm listening music while I'm working or I'm doing task on Firefox I used to have no problem I just Open YouTube and let it play on auto play and it goes no matter what. About 6 months ago I started to experiment some problems the video stop all the time even if I have a playlist going on like 50 song one after another it will stop once in a while for no reason. It pissed me off so much that I have to change my browser by default and I don't like other browser I use always Firefox with DuckDuckGo so when I'm trap to use other browser I get mad the only one that functions very good it's on edge Microsoft and seriously I cannot stand this… I'm forced to use YouTube only on edge it's the only place that it works no matter what it never stop. It used to be a little arrow in the bottom of the screen, a button that you can click on and off to Auto play or not, this button disappear it's not even there no more. This button Auto Play it's not there in Edge or Google Chrome but YouTube works for them not for Firefox so what is the problem it's not the setting is it YouTube that's got problem with Firefox? I don't know, it must be a way, a back door because I need to go back with Firefox I need to go back with DuckDuckGo. I'm pissed because I have to leave just because of that and that it's no compromise for me my music will pass before everything else. I don't feel like asking question to the community because it takes months before they answer you if they do. It's no customer service for Firefox or Mozilla whatsoever they don't answer you they don't talk to you they don't fucking care and this is another thing that pisses me off because they have a good thing going on but they don't care about the people. This was, this is what I did so far: Disable Hardware Acceleration "Performance" section.

I unchecked "Use recommended performance settings."

I unchecked "Use hardware acceleration when available." Clear Cache and Cookies I cleared the cache and cookies preferences privacy: Under "Cookies and Site Data," I clicked on "Clear Data."

Extensions about:addons I disabled all extensions to see if the problem persists… nothing happen YouTube I used YouTube in a Private Window … nothing happen YouTube Playback Settings I changed the video quality … nothing happen
