Firefox Support Forum

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.

YouTube keeps blanking out at regular intervals. I can watch videos and try returning to the main page, only to load as blank, with only the menu icon in the upper left corner showing. This keeps happening, and the only solution is to close the browser and use Wise Disk Cleaner (or similar software) to clean the cache before restarting the browser. I have to do this several times pr. Day.

I have tried the most normal solutions I have found, already posted, like:

- Disabling Hardware acceleration - Uninstalling Ad-blockers

I have the following add-ons installed:

- Dashlane - Adblocker Plus - Honey - Return YouTube Dislike - Zotero - Express VPN - LeanLibrary

Are there any other options to attempt to correct this extremely annoying problem? I just want to surf YouTube in peace.

Thanks for any replies in advance!

This URL below will return a XML file in Edge/chrome but not in Firefox. I use Joomla as a CMS and it's extensions to display a RSS feed worked fine in both browsers until a couple of months ago. I've tried with a vanilla Mozilla/FF with all extensions disabled but still will not return the XML file

hi when I go to github it says Did Not Connect: Potential Security Issue whereas before it worked fine but now it doesn't :/ I have watched so many tuto on yt but no one work i have clear my data i removed my antivirus and all my extensions and went into private browsing but I still get this error.

I have been using Firefox since I cannot even remember when. I never had a problem with Windows 10, but since I got a Windows 11 Dell laptop a couple of years ago I have been unable to use some websites. This one in particular: french.typeit.org. It allows me to write in French, with French accents and some special characters and letters that do not exist in an English keyboard. Always worked flawlessly with FF on Windows 10, but with Windows 11, I am able to write in English, but when I hit a French character nothing happens. I tried disabling all extensions, deleted history, etc., in vain. I contacted the app developer, and after a back and forth exchange with him he determined Firefox sees my laptop as a mobile device, and that is why his app will not work. He said he thought there was nothing I could do on my end, so FF needs to do something. I use this app with the Brave and Edge browsers with no problems at all, but I would much prefer to use FF if I can. Thank you.

There is an error occurring on the payment page.

Most of my settings were changed on update. Had to reopen session and still absolutely NO PAGES WILL LOAD. Submitting this report from Google Chrome because firefox is COMPLETELY BROKEN!!! Are you hoping I will change to a competitor browser??? This is a complete screw up and a no started. Even took away several buttons for extensions I've used for years. I AM A FORMER IT GUY and I can't make it work. Patience is already wearing thin!

I use mozilla firefox as my main web browser, and youtube sometimes does sometimes doesn't load (picture below). This happens only on firefox. Every other website works fine tho.

I am trying to access "Boston Scally" website. When I enter their website to window shop, there isn't a problem, but when I go to order a particular item, the web page goes nuts. I am having this issue with a number of different websites when I try to order or pay for the product.

Website is being set to reject Firefox browser only, asks me to use alternative, why?

Enter site: https://mylotto.co.nz/

this appears

I don't know if it is the last update, but since this week the scrolling menu on numerous website on firefox become messed up and instead having their usual limited height (like no more than 400px) when there are numerous links in the menu, they now reach the bottom of the windows.

I added some image to explain the problem with two sites: one screenshot show firefox bug, and the other is a screenshot (from edge) to show how the scrolling menu with limited height was supposed to be before the bug.

Also the problem appear even in the debug mode, so i doubt it is an extension trouble. How to solve this problem?

I get phone notifications that a streamer is live but when I go to their page on Twitch on my laptop, I see them as offline (screen shot).

I've tried clearing cache and cookies and do not currently have any pluggins that affect Twitch.

As of a few days ago my login to my bank's website is not working. I can login, but the main page which should display accounts, etc. only displays the top half of the site, but not the lower half that should display the account information. I tried chrome, and that works fine. But I was wondering why FireFox is not displaying the website. I've been in contact with my bank and their I.T. department. And they claim there have been no changes or glitches, and their website should work with all majore browsers, including F.F. I do have a password manager, but I disabled that for the bank website. I've cleared cache numerous times. Rebooted, etc. I know there was a Microsoft Windows update a few days ago. In fact they sent 2 updates almost back to back. Which is unusual. I understand there have been cyber attacks recently. Don't know if that's related. Any ideas on how to get F.F. working on my bank's website? Thanks

between this netflix error, this amazon alert, and youtube auto switching to 360p it's become increasingly difficult to access media. i've called netflix about this and they had no idea what the code was and have not gotten back to me with a resolution.

does anyone know what's causing these issues? is it just companies being hostile to firefox specifically or is something wrong?

i've cleared my cookies and cache, i've restarted several times, i've logged in and out of everything. i'm on version 120.0.1

i dont know why but when in fullscreen sites have weird borders around them it seems to be a firefox issue i dont know how to fix it.my computer runs windows 11 if that helps.

Menu-pulldowns malfunction, after a while of usage, on a large 2ndary monitor, on M1-Max macOS Sonoma -- I have to shutdown, and restart Firefox to re-activate !

I can log into preply.com with Chrome and Edge, but always have problems with Firefox. I was able to log in once, but after that, I can't log back in.

Recently I had to reinstall Windows, and saw the opportunity to try getting this to work. Installed Firefox, but *before* I logged into Mozilla Sync (so I'm working with a 100% fresh installation with no history of having Firefox installed) I tried to log into preply.com. It worked. Then, I log myself out and try to log in again, and once more, I can't log back in. I'm attaching a screenshot of what I see when I try. Please note -- I have no bookmarks, no extensions, no addons, no browser history. Everything is tabula rasa.

I found this page:

https://support.mozilla.org/en-US/kb/fix-login-issues-on-websites-require-passwords

and followed it to the letter, meticulously, to no avail. I still can't log into the site with Firefox. Chrome and Edge, yes. Firefox no. I only have Edge because I can't uninstall it. I only have Chrome for situations like this, where Firefox doesn't work. Firefox is my main browser, and I really, really would like to figure out what's happening. I can't understand how this problem persists when the browser is freshly installed; I haven't imported one bit of data yet from my sync account.

Can someone more experienced than me please help?

Hello,

I have been using CSS to change the looks in websites for a while. First, I use the 'inspect' function and then permanently make changes using Stylus.

For a month or so, I have not been able to apply certain custom fonts in either using the 'inspect' function or the stylus extension. Afterwards I tried the same on a fresh new install of Firefox Developer edition with no success either.

The problem in question is that I am able to apply custom fonts with names composed of a single word such as "Times" "Arial" or "Georgia", however, using fonts with two or more words such as "Arial Nova" or "Californian FB" does not work. Oddly enough, the system font "Segoe UI" does work, as to why perhaps this bug was not detected in tests.

In short, I am not being able to use custom css fonts with two or more words in any Firefox desktop setting.
