Firefox Community Forum

I recently upgraded FF on this computer and can no longer sign in to my att.net email account, although I was able to sign in on another computer on FF earlier today. I just get an error message and Att can't help...is there a setting that has me locked out? I can also access email on other browsers just not the FF version on this computer.

This is pretty shady Mozilla.

When disabling only one setting: "Allow Firefox to install and run studies" it wrecks this site whether logging is or continuing as guest:

https://appointment.questdiagnostics.com/schedule-appointment/as-personal-information

Even after logging in and everything running normal, disabling the studies run by Mozilla and a quick refresh breaks the functionality of the page. All cookies were accepted and the sharing of location was allowed. On a fresh, first run, wide open Firefox people. Literally, the only change that was made was unchecking that one box. In disbelief, i tested it over and over.

Why would disabling a telemetry setting, something that should be optional, cause this to happen? Seriously, what could possibly be the reason. I'd love to hear it.

This was the final nail in the coffin to me and this is since the 0.9x days.

As of February 13, 2025 the front page of the Washington Post website does not load correctly in Firefox 115.20.0esr in Mac OS 10.13.6. The problem persists even in safe mode. Thank you.

Hello, vinted.com/ vinted.co.uk has been throwing me all sorts of strange errors and security concerns over the past 4-5days. Any ideas? Thanks for your help!

Good day After the last update, the browser changed the appearance of the YouTube player. In all other browsers it is standard, please help return it to how it should be

Youtube is nonfunctional on firefox as of April 29 2025. It was all working fine last night, then I woke up to no youtube. It loads the website as a blank screen. Videos can be accessed by going directly to their URL, but no recommendeds load in, no comments section, even the title and channel information is unavailable. I would say none of the buttons work, but there are no buttons to test. It works fine in Chrome still. I know it's not my extensions because I tried removing them all, and it didn't fix it. I know it's not my cache/cookies, because I cleared that too and it didn't fix it. I know it's not on Youtube's end, because it works fine in Chrome. I know it's not an update issue, because I updated my browser and it didn't fix it. Please. I want to be able to use youtube in firefox. Please help me fix this thing. I have attached photos, but I suspect they'll be more demonstrative of the problem than useful for troubleshooting.

When I try to compose a new email, or reply to one, the pane opens to compose the email, but immediately closes before I can enter anything, reverting back to the Inbox. A new, empty draft gets created. But there is no way I can create a new email. Problem does not occur on other browsers. If I open a "New Private Window" and sign in to Outlook, I can then create the email there, but after a while the same problem occurs in that window too. Tried clearing Firefox cache temp files and cookies, but that did not resolve the problem. Using web based Outlook, Windows 10. Firefox is up to date.

Any suggestions?

Some web sites have begun to not work with Firefox browser on Windows 7 64 bit. Is there anyway to get a version of Firefox that that will get me back to working as well as before 4/9/2025. My Firefox web browser says it is fully updated. If Firefox browser is to no longer work with Windows 7, can you suggest a simple browser that can be downloaded for Windows 7 and tell me where and how to download it?

Hello, everytime I try and upload a video on YouTube with firefox, the video gets stuck at 0% processing,

This never happened in my 4 years of youtube and recently (a few weeks ago) this starting happening. I use firefox to stricly upload videos, and use chrome to browse with my other account casually.

Now Im forced to upload using chrome but I want to still use Firefox to upload videos. anybody know why this is happening? I've cleared cache serveral times and it still won't work. I have no adblockers etc.

I cannot load the IRS webpage for my account. I load the following page: "https://www.irs.gov/" click on "Sign into your account" which directs me to another webpage: "https://www.irs.gov/your-account". I click on "Individual-sign into online account" and get the following error: "Error from: https://sa.www4.irs.gov/sso/?resumePath=%2Fas%2F0ysmHPaqAO%2Fresume%2Fas%2Fauthorization.ping&allowInteraction=true&reauth=false&connectionId=SADIPACLIENT&vnd_pi_requested_resource=https%3A%2F%2Fsa.www4.irs.gov%2Fola%2F&vnd_pi_application_name=OLA Reference ID:"

I can get into the Direct Pay website with no problem. I also can access my IRS account using my IPhone which makes me think this is a browser problem. I have disabled anti virus with no success. I called IRS and they have never heard of this problem and had no solution and said they didn't handle this issues.

Any suggestions please?

A number of important (to me), websites (pension and wages) ask for login details, including password, pin and in some cases using 2FA, will not still allow me access. I have tried changing the passwords etc. However, this seems only to allow access one time only. I am entering the passwords correctly and other info but I can not consitantly access the web pages. I do not use google or Bing search, only Firefox and Duck Duck Go. The last time I was able to use the passwords etc freely was around mid December 2024. I have searched for probable cause and remedy but all to no avail. If I try to access on my iPhone or tablet I can access some but not all. I did have Dashlane on my PC and laptop but have since deleted it. It was not on phone or tablet.

Any advice or help please?

Dear Mozilla, your browser has a small error. I want to talk to someone on Facebook who I talk to often, Firefox allows it. For those I rarely talk to, when I put the cursor on the phone icon, it says that it is not supported. I think this is a bug. Therefore, I have to switch to another browser to talk to someone who rarely talks. Please fix it
