Firefox supportforum

I am unable to login to the DVLC. I get as far as the enter reg number of a car to check it,s been taxed. Then after I input the reg number the next page tell me it is an insecure page. This also happens on my laptop. On both desktop and laptop I am using firefox with duck duck go as an add on. However. In using my mobile with the stand alone duck duck go browser, I can log in and complete the task. This points to a problem with Firefox. Any advice's. This seems to be recent as I have used the laptop and desktop to use the check for a taxed car system ok in the past.

Hey all, as of the past few days when I get the prompt to enter my password on Outlook.com (And microsoft.com) and hit 'sign in' the page just reloads and nothing happens. There is no failed login message, the page just reloads like I didn't hit sign in. I have disabled all of my extensions, cleared cookies and cache, ETP... with no luck.

Works fine on Chrome for android...

I'd really like to stay with Firefox so all help seriously appreciated

I was using Amazon just fine a few days ago. When I tried to open an amazon link yesterday, I got the message: Secure Connection Failed. I tried updating my browser and clearing my cache and cookies. Please fix

I can no longer log into my social security account using Firefox, but the login does work on edge. When I try login on Firefox, I get the following error message:

Bad Request

Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit.

The initial web site is https://www.ssa.gov/. From there I hit "Sign in", and get to https://secure.ssa.gov/RIL/SiView.action using Edge, but get just the error message using Firefox.

There is another route, which is through https://www.ssa.gov/myaccount/. Hitting either account or sign in on that page will work on Edge, but gives the same error message on Firefox.

Hi,

The website below is not opening in Firefox but in Chrome. What setting is missing in Firefox? https://de.yvesdelorme.com/

I'm having trouble with Firefox where images aren't loading on some websites, even though they display fine in other browsers. I've tried clearing the cache and restarting Firefox, but the issue persists.

Is there anything else I can try to fix this problem and get images to load properly?

I have a well hidden web server that uses HTTP. I need to download files from that server. After the newest update, Firefox now gives a warning about the website and on that warning is a button to "Allow Download". However when I click on that button, the file that gets downloaded IS NOT the file that I was initially attempting to download. It looks like it is a copy of the web page that was being displayed at the time. I noticed this behavior at work. I went home and used Firefox to connect to the server and everything connected and downloaded correctly. I went to see what version of Firefox was running. It was 124.0.2 and there was a button saying "Update Firefox". I clicked that button. My home Firefox updated to 125.01 and my home version of Firefox now also downloads the wrong file.

Hi there,

About 4 days ago, hotmail suddenly stopped loading on Firefox (though I can still access it on Safari). I've tried clearing my cache and add-ons, etc. I've googled a ton and tried all the things I can find to try, but nothing is working. I am by no means a tech person and so I'm out of ideas and need some help. I know I can use Safari, but I really hate using it and prefer Firefox. Any ideas on what to do? I am using a MacBook Pro - Sonoma 14.4.1

Thank you so much! Jocelyn Pascall

When using picture in picture on Prime Video, my subtitles aren't showing up in the window, but instead on the original page, despite prime video being one of the original supported websites. Any ideas on how to fix?

I have always been able to connect with Navy Federal Credit Union for my banking until a few days ago. Every time I click on the accounts shortcut I get the FAILED TO CONNECT window. I can open my e-mail and ALL other websites. I can connect with Goggle but I've always preferred and used Firefox. I have used Firefox as my main browser for many many years. What is the problem??

Anyone experiencing issue with YouTube on Firefox - I am not able to select suggestions on YouTube search using up/down arrow keys - On Ubuntu 22.04 - Firefox 124.0.2

I have a website that I host. It is behind a proxy. It is a resolvable FQDN with DNS hosted by a major provider. The issue is when I browse to it via Firefox 124 it eventually errors out with connection reset, however if I open a private window it goes right there. I have tested other browsers and it works fine with them (Chrome, Safari, Vivaldi). I thought maybe it was plugins so I tried shutting off plugins one by one restarting after each one and that did not help. I tried in safe mode and could not get there. So I backed up my bookmarks and wiped out the directory and all for Firefox and tried on a fresh directory and that did not work except in private window mode.

For about a week now YouTube doesn't display correctly. No content shows. I can open private browsing and works fine. Also works fine on other browsers just not Firefox.

I'm on an iMac running Firefox version 124.0.2 and I've tried disabling all add-ons but nothing has changed to the browser so shouldn't cause any issues.

Any help?

i’m trying to open blackboard.com but it keeps telling me ( Did not Connect: Potential Security Issue ) some youtube guides say that you can modify the enterprise security roots from *false* to *true* and it will work, but is it safe to do that? and is there any solution the problem?.

Hello guys, so in the past 2-3 days i started facing Cross-Origin Request Blocked for a lot of websites lets take chatgpt for example, if i visit it i get:

Content-Security-Policy warnings 2 Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://cdn.oaistatic.com/_next/static/chunks/sso.74deac81d652476b.js?dpl=f90a861ef09abad575887be5d613ce15a4fdb6d9. (Reason: CORS request did not succeed). Status code: (null). The resource from “https://cdn.oaistatic.com/_next/static/chunks/sso.74deac81d652476b.js?dpl=f90a861ef09abad575887be5d613ce15a4fdb6d9” was blocked due to MIME type (“text/plain”) mismatch (X-Content-Type-Options: nosniff).

and its getting so annoying that its blocking a lot of websites, i tried chromium it works fine and works awesomely no cors no problems. I even tried to disable the firefox protection, dns over https on/off, change my main dns upstream, installed firefox developer, compete uninstall/reinstall, cache clear from installers and from firefox it self nothing is working. I will provide firefox developer edition troubleshooting information but keep in mind it doesnt work on both firefox normal and developer

Please any help would be appreciate it.

Firefox v124.0.2-1
