None of my streaming networks Peacock and Netflix wont work on Firefox anymore. We get errors saying our Browser is no longer supported. When checking, there is no new update for Firefox.

Why does Vanguard say my Firefox browser is no longer supported. It says I have to update to the latest version. I am using version 115.26.0esr (64-bit) and it says Firefox is up to date.

Their website seems to work okay, but they say I may not be getting the "best experience," whatever that means.

Any information about this would be appreciated. Thanks!

When I try to log into Xfinity to pay my bill I get this. Is it related to Firefox? Thought I'd ask you before I tried to work my way to a human at Xfinity

I have no idea what Firefox did with the update but it made navigating my Substack a royal pain in the neck. I cannot post, cannot edit, cannot share posts. Very infuriating. I have had to go back to Edge to get these features to work. Dashboard link does not work. Share link does not work. Cannot post comments. Infuriating.

Chase bank online is now requiring a later version of Firefox than my Mac will support. I currently have Firefox version 115.30.0esr. Now I am unable to access my account on line to see purchases. What is my work around? I thought there was software that could be installed to "spoof" chase into thinking I had a later version of Firefox. Both of our computers are from 2011 and 2012 so neither one will accept the latest version of Firefox. Many thanks in advance for any advice.

Mozilla needs to come up with a permanent solution to this issue. I know that Google probably started it by somehow changing YouTube, but Mozilla needs to react and come up with a solution.

georgiasown.org does not fully function in firefox browser. The website opens but some of the graphics are missing and when I click on Log In nothing happens. This started about two weeks ago. Have been daily going to this website for over 10 years in the Firefox browser. I do not have this issue when using Microsoft Edge browser.

When trying to access windinfo.eu, I get the message "you are not allowed to preview snippets". Other websites work o.k. I had used the snipping tool on a different website, but not on this one. The problem persists even after deinstalling the snipping tool and restarting. On edge, I get access to windinfo.eu.

Many thanks in advance for your help

I just bought an HP Omnidesk M02-0085m PC running Windows 11 Home edition. For some reason Prime video works in other browsers, but in Firefox I get audio and a black screen. I am not using any ad blockers and I have tried toggling performance settings on/off. Any suggestions?

I'm using the latest version of Firefox. A website I visit a lot - https://www.underconsideration.com/brandnew - uses the Disqus system in its comment section. The problem is that no comments at all show up when viewed in Firefox, I have to switch to Safari just to read and engage with the comment forum. Why is this happening? Any ideas? Thanks.

I was having problems with the firefox browser. This has never happened. I always use firefox and the company said that firefox was compatible to there sight but I could not access.

When I attempt to log into my ssa.gov account thru either login.gov or id.me with firefox browser i get the following message. "Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit." I can access both with google or edge. I am running windows 11 with most recent firefox update What do I need to change in my firefox settings?

Hello:

  For a couple decades now, my favorite browser has been Firefox.

I've manually enabled my Web Cam and Mic in the browser settings to work with Facebook. It seems like Firefox still DOES NOT SUPPORT Facebook 's Video and Voice functionality. Anyone know, if there's a possible fix for this? Is Firefox Software Development Team working to correct this issue and is there a possible projected date on this resolution ?? Please don't hesitate to help me with this technical problem...

Thanks!

Hi, I need help with an issue related to how my website https://forganica.com/ loads in Firefox. The site works fine on Chrome and mobile browsers, but in Firefox some elements are not rendering correctly and the layout shifts on scroll. Is there a recommended way to debug layout or CSS rendering issues specifically in Firefox? And is there any Firefox-specific setting or developer tool I should check to understand why my site behaves differently?

Hi

You did an update to Firefox about two weeks ago & now I can't login. Had to call EDD yesterday & today to talk to an IT specialist. She told me that Mozilla never contacted California EDD & for the last two weeks people, myself included haven't been able to login. She told me to use Chrome or Microsoft Edge, both of which I absolutely HATE to use. Well guess what I was able to login using Microsoft Edge.

Here's the steps Login They send you a 6 digit text code. You enter the code Then you get a pop up message that something went wrong & call the 833 - 876 - 9333 for the IT dept. Which only takes about 20+ trys to get someone.

PLEASE CORRECT THIS SITUATION!!!!
