I use the IRS form filler to pay my taxes...have for years with Firefox browser. This year (for 2024 return) when I sign into the site the 1040 form does not display correctly. the boxes are to the right and below the actual placement. I emailed IRS who said it is a setting in Firefox. I tried the site using Microsoft EDGE and it displays correctly. I have searched for possible solutions and tried them all like using/on and off excelerator, letting Firefox chose size and colors of sites, turned off Noton etc. I posted another question here but no replies or looks so maybe I did something wrong so I will try to post again. I have W10 fully updated and Firefox too up to date. I understand I could use Edge but never had to and prefer to use Firefox as I have before. any suggestions would be appreciated or where I can report a possible issue with Firefox. I have attached a sample. thank You

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.

I've freshly reinstalled Windows 11 and after trying to access and watch a movie on any of these sites I get an error (see the pictures).

Browser version: 137.0.1 (64 bit) Widevine version: 4.10.2891.0

Already tried to disable/enable DRM. Already reinstalled firefox. Already manually installed widevine. No clue what could be causing this issue.

I'm trying to log into this page: https://accounts.firefox.com

The sign up or sign in button doesn't work. The first time I click it, it immediately refreshes. I click again and nothing. On the 3rd click, it just spins for 30 seconds then goes back to being blue. This continues every time I attempt to click further.

I can login on this page just fine using Firefox on my android phone. I can also login using the Edge browser. Matter of fact, I had to use Edge so I could post this issue.

This is a completely fresh install of Firefox, on a completely fresh install of Windows.

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.

For a few days, for unknown reasons I have been unable to access my blog..."Kitchen Connection". This has never occurred before, and it is very annoying. I have been blogging for many years.

Your assistance in this matter would be appreciated. Thank you in anticipation.

I've tried submitting the above a few times...and for whatever reason, it has not gone through to you, it would appear.

Second post trying to figure out what is going on.

I'm getting the notification that I need to update Firefox, so I click the "download" button which takes me to "https://www.mozilla.org/en-US/firefox/new/?reason=manual-update", I select the "Download Firefox" button and after a few seconds I get a "Secure Connection Failed" message.

Usually I can just open Chrome and download the Firefox installer but today I'm getting an error stating that "download.mozilla.org" is using certificates from a different website.

Is the download site busted, or is this just a me issue?

i recently disabled 2fa and installed a new authentication app: Ente Auth. i keep getting invalid code each time i enter the generated code. i tried both options, scanned the QR code and entered the secret key manually. i used authy with success as my auth. app with firefox but can't use authy anymore. keep having issues setting up 2fa with other auth apps. thanks for any help you can offer. peace, Adrian

Hello, Thanks in advance for your help. I am having trouble logging into "trusted" web sites with Firefox and every update seems to add to my problem. By "trusted" web sites I mean sites like Charles Schwab, Spectrum and iCloud as well as my city's water department and my local hospital's portal. It doesn't matter whether I use "normal" Firefox or its privacy mode or safe mode-the problem persists. I am running Firefox version 134.0.2 but the problem goes back several months. I have Windows 10 and use Malwarebytes Browser Guard. The only other add on I use is Print Friendly & PDF. It doesn't matter whether these addons are running or not. The problem seems to involve either a loop, blank fields or very odd error messages. Some examples are below:

iCloud allows me to get to the point where it asks me to supply the 6 digit verification code. I enter the code and the site loads. Approximately 2 seconds later, before I can navigate to anything in iCloud, I am taken back to the log in screen to start over. The loops repeat as often as I want to try. Clearing cache and history does nothing. Since there is nothing abnormal (no error message or blank fields) I have not included a screen shot.

Spectrum allows me to enter my credentials waits a while and then gives me an odd error message about Feature Unavailable and suggests that I try logging in from home. I might add that all of these problems occur while I AM at home. Screen shot attached.

Charles Schwab allows me to get to the log in screen but the screen is unusable. There is a message that the session has timed out and I need to log in. The log in sections of the screen are blank which leads me to believe that the page is not loading all the way but that is a guess. Screen shot is attached.

I can log into all these pages with Edge (which I dislike using) with no problems at all.

I have Firefox set to automatically delete cookies and site data when closed. Privacy is set to Standard.

I would really appreciate any help that you can give me. Please note that the screen shots are BMP files that I had to rename to GIF files to get them to upload.

Thanks again,

Charley

Are you aware of the incompatibility of these two government websites that no longer are compatible with Firefox? The VA appointments of the HealtheVet site are no longer working and when I called for support they sent me to the chrome browser and says it is not compatible with Firefox. The same is now also true with the SSA website. This is a problem with Firefox or the government being forced to use chrome compatible sites only. YES, it needs to be fixed on one side or the other. Do I need to contact Congress?

So I understand this: https://support.mozilla.org/en-US/kb/xframe-neterror-page and the reason it exists, but I need to find a way to turn it off because it's literally blocking me from accessing the Library of Congress webpage inside the same browser for my job. It's not a malicious site, but I can't figure out how to tell Firefox to stop blocking it as if it was a malicious site.

Help.

All of my addons are disabled and won't re-enable!

They all say "addon name" could not be verified for use in Nightly and has been disabled. See attachment clipboard00.jpg

If I try to install an addon from the recommended extensions settings (for example "return youtube dislike ") I get a message bubble stating "The Addon downloaded from this site could not be installed because it appears to be corrupt. {OK!}" See attachment clipboard01.jpg

The message above about addons appearing to be corrupt happens if I go to any of my current addon pages and try to redownload them.

It looks like some sites are not working properly, two examples I can give are google sheets&docs, in the attached image you can see my sheets are not being shown, note that if I directly access a sheet's link it does open.

The second example is some websites with media players just load infinitely (YouTube works).

Also added network tab non 200 status code requests images.

Things I've tried:

• Disabled "network.dns.disablePrefetch".
• Tried troubleshoot mode(meaning those requests that were blocked by ublock are not the problem).
• Deleted history including cookies.
• Private Browsing.
• User Agent masking
• Reinstalling

very frustrated, and pissed at how programmers always screw things up that are working just fine by upgrading crap. Now, I have suddenly had all of my addons quit working, was forced to update my firefox. Nothing changed, and it still shows that I am using version 105, instead of the all-new, better and fancier, singing and dancing crap that is being forced upon me.

Hi.

Can't access router gateway since last week

Gives error: Error code: SEC_ERROR_REUSED_ISSUER_AND_SERIAL

Gateway is http only, I can access it fine via Edge and Safari iOS

I tried disabling https-only though it used to work fine before with a saved exception.

Made sure Win10 firewall allows Firefox for private/public

Followed the help link and deleted the previous certificate from the certificate manager, but I can't find anything relevant under the servers tab

I'm at a loss. Many thanks in advance.

I have a new macbook air running Sequoia 15.3.2, firefox is up to date, my battery which should technically last about 12 hours and I only get 5. Ran through everything with Apple and they said it is a Firefox issues. I don't have any extensions, add on etc. Thoughts?

After the recent bunch of windows updates i started noticing youtube loading much slower and other websites acting strange. Just now i tried to look at a link https://steamusercontent-a.akamaihd.net/ugc/47948470127416586/912CDEE3AD8B94CF3122B7338E89E24C9B6EC29D/

I get "No video support and MIME type found". I have uninstall/reinstalled, checked codex, disabled addons and downloaded Microsoft windows media pack, then restarted the computer.

Nothing seems to work. But i had to reinstall Firefox again because all my tabs would crash after the last reinstall.

I have set E:\ as my default download location. However in some cases Firefox does not respect my choice and silently downloads stuff to C:\Users\Name\Downloads. I really hate this. One example, a pdf downloaded from here https://scribd.vpdfs.com/. Please fix it. Thx.
