Firefox Community Forum

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.

For the past two evenings I was able to open the xfinity stream menu & channel lineup but could not open the "play" function on any channel that was selected from my search box or any selected channel from the lineup. Xfinity customer service had vague topics, nothing addressing this issue. Trying to determine if this is a comcast issue or an issue with Firefox. Help would be much appreciated.

Is anyone else having problems with the latest version of Firefox not rendering Google Calender, Amazon.com and other websites?

channel 4 repeatedly gives me this message when i enter my e mail address. there is nothing wrong with the address. Sorry, something went wrong. Please try again or use a different browser. after dozens of attempts it has let me in for the last few days. Today it does not

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)

Hi, Using FireFox to log into Le Chat Mistral doesn’t work on my Ubuntu 22.04 PC. I enter the email to verify the A/C then enter the code number. Next it says ‘You successfully verified your email address’ and pressing 'Continue' I go back to 'Verify your account' page and round we go again??. There is no problem on my Windows 11 laptop so what's the issue with Ubuntu or have I done something silly? Thanks

I have a set of fields I usually input in https://stockcharts.com/h-sc/ui every time. In chrome, these the search fields are saved even when the tabs are closed and reopened. But in Firefox, these fields are not saved after I close and reopen the tab.

I have already created exception for https://stockcharts.com in Enhanced Tracking Protection and Cookies settings but the issue still persists.

The lack of visible emotion icons only occurs on Facebook. Only two are visible. They're there and work with a mouse click, but they're invisible. Reinstalling Firefox didn't help. The problem doesn't occur in other browsers.

Firefox can't connect to www.123greetings.com but Chrome can.

Hmm. We’re having trouble finding that site.

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

I am using the Raindrop (raindrop.io) bookmark manager. It has been working fine on Firefox for years. However, with my recent update to Firefox 140, it is broken. Specifically, I can no longer use the highlighting function. It works fine on Chrome, but not on Firefox. I've seen several similar reports on Reddit's Firefox forum (r/firefox).

What to do? I don't want to have to switch to Chrome. Suggestions appreciated.

Something happens to the images when I upload them to any service in the Mozilla browser. Instead of the image I see a strip. There are no such problems with any other browser. Attached is an illustration.

I am trying to install Keeper Password Manager and use Yubikey login. Setting up the Yubikeys with Firefox does not work. I used Chrome to create the Yubikey login and they work with Chrome. I never normally use Chrome, only Firefox. When I try to login to Keeper on Firefox I get an error message instead of the login.

There is one particular website that I use quite frequently. Lately I haven't been able to log onto it without encountering a page verifying I am a human, and I can't proceed (the page just loops). This has happened on other browsers too, though I fixed the problem there by disabling my adblocker. But that doesn't help here on Firefox. Any suggestions?

recently some websites won't open. in other browsers sites open fine. problems with pinterest.com figma.com cleared the browser, deleted cookies and cache, reinstalled the browser everything opens in google chrome, i attach screenshots

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
