Firefox Support Forum

I can no longer view YouTube videos in Firefox browser because they think I have some kind of add blocker installed. I have never installed such a thing and have no idea how to fix what they are demanding I must fix in order to continue with YouTube in the FireFox browser. In the mean time I have to use some other unfamiliar browser just for YouTube. It appears that some kind of incompatibility has evolved in the recent two or three weeks between Firefox and YouTube.

I am unable to sign into Costco.com using Firefox. I get an error message:

    "Bad Request - Header Field Too Long
    HTTP Error 400. A request header field is too long."

Turning off all extensions didn't help. Opening a private browsing window DID work. Using Chrome DID work.

Thanks!

Starting today I am finding it extremely hard to login to some websites. All Firefox does is just sit with a spinning circle after entering a user name and it locks up the browser to a point the I have to go to the Task Manager to stop the FireFox process. I have restarted my computer and refreshed FireFox. I have scanned my computer for malware using Norton 360, Malwarebytes, MSERT, and Windows Defender and all negative. I am having no trouble signing in to a site like https://my.account.sony.com using Edge but using FireFox now is impossible. This needs to be fixed.

I access a CCTV Network Video Recorder on the same private/LAN that I'm on using an PC via HTTPS. It's been working fine for nearly a year. Recently it won't access via HTTPS any more with the Error Message "Secure Connection Failed An error occurred during a connection to 192.168.1.30. Certificate key usage inadequate for attempted operation. Error code: SEC_ERROR_INADEQUATE_KEY_USAGE

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the web site owners to inform them of this problem."

I've contacted the vendor but they seem at a bit of a loss. I can connect using HTTP, and an Android App (spit) still works too. I did find a Stack Overflow article from 2020 mentioning a possible corrupt cert9.db and/or cert_override.txt files, but as it's so old I wanted to ask for further advice before I start hacking things around. On another PC using the same browser version on the same network I get the attached response, not the same as the one I get and it will allow me to accept the risk. Can anyone help please?

Hi everyone, When i go to the website config.office.com in firefox there is just a white screen. Nothing more. Instantly white. I have checked if this is an issue at the side of Microsoft but it doesn't look like it is. The website does load correctly in Microsoft Edge.

I tried the following in Firefox: - Firefox is up to date (Version 115.0.2 64 Bits) , I have had this issue in other versions of Firefox too. It's not a new issue in this newest version. - Tried disabling all the security features in Firefox, disabling all add-ons, and disabling the extra security for cookies - Starting firefox in safe mode (Shift click on firefox, then open the website) - Checked the Network inspector. All packets have status 200 (See the first screenshot)

You can check the second screenshot for the white page.

Some help is appreciated :) Thanks!

Hi all,

Apple has revised/updated their iCloud web portal. The backspace key no longer registers in the iCloud Calendar app on the web. This is specific to Firefox on Windows - I've tried other web browsers to access iCloud web portal and Chrome's backspace key registers so its not an Apple iCloud problem, just Firefox. Is there a setting or do I have to wait for an update?

Thanks in advance.

Majority of the songs do not play and I'm given with a pop-up, "Spotify can't play this right now. If you have the file on your computer you can import it."

I will play a song from a playlist and is given that pop-up, it will continue skipping to the next song until it plays, but only for 9-10 seconds until the song mutes, to specify, the dot (when hovered on the progress bar) will still move, indicating that "it's playing".

Some clarifications: 1. I use Spotify Desktop app (windows), Spotify App (android), and Spotify Webplayer on Chrome and Firefox. Everything works just as fine on all of these, except for Spotify Webplayer on Firefox. 2. Skipping to a later timestamp does not unmute the song. 2. I have Spotify Premium 3. I have no VPN 4. I am running Firefox with an ad blocker 5. I am running Chrome with an ad blocker (same ad blocker in Fifefox) 6. I am running Firefox to the latest version (Firefox 119.0.1 (20231106151204))

What I've done so far: 1. Cleared caches and data. 2. Updated my Windows to the latest update available - Win10 v.22H2 3. Signed-out of Spotify for all my devices, then logging-in first on Spotify Desktop (this automatically redirects to Firefox webplayer) 4. Ran Firefox on "Troubleshoot Mode" 5. Un-checked and re-checked "Play DRM content" setting. 6. Disabled and re-enabled the plug-in "Widevine Content Decryption Module by Google Inc". (this plug-in is last udpated on November 17, 4.10.2710.0

I'm including this link from Spotify's Community page.. where two other users, who commented it is only with Firefox (webplayer), are experiencing the same problem as I am. https://community.spotify.com/t5/Desktop-Windows/Spotify-can-t-play-this-right-now-If-you-have-the-file-on-your/m-p/5679914#M123192

No videos appear at all on Teachable, just a blank space where video should be. I have allowed video and audio (video and audio work on many other sites). I have cleared my cache. I have to use a different browser to use this site. I have also noticed other sites that have the same problem.

The problem is : Some of the time FF just records 0 bytes file and says nothing. I suspect that FF inspect the URL of the links and discard ( perhaps for security reason ) ones that do not begin with HTTP.

The bypass is : One has to copy the link and insert in in the new page of FF.

The solution would be to change FF code.

Thank you.

What is going on?

After doing a reset to try and get rid of the yahoo redirect malware attached to the Firefox browser, now I cannot access google search engine within firefox, or my gmail email account. I get the error messages attached below. I have spent hours looking on your support pages and tried all ways and NOTHING WORKS!!!!

FIrefox has been my default browser for years but if you cannot fix this very annoying and frustrating bug, I will be forced to your Chrome.

Very unhappy with this

I am using a MacBook Pro and latest version of FIrefox 100.0

PLEASE HELP ASAP!!!!!

Until the most recent update of Firefox, I was able to access atrribute data of a GIS map feature on the GIS Open Data, State of Michigan website:

https://gis-michigan.opendata.arcgis.com/datasets/2020-voting-precincts/explore?location=44.909859%2C-86.310800%2C6.97

Now, I can not click on any feature. I can do this, however, using Chrome. What is the issue, here?

(This issue has been happening for several months, perhaps even a year or more)

My issue's example is me trying to log in to Duolingo. When I try to log in with google, a popup appears where I select which google account to use, the popup closes, and then the sign in button loads perpetually. I left it to load for over an hour and nothing happened.

I tried the same thing with Microsoft Edge and I could log in with google perfectly fine.

This has happened to me on other websites too, but the issue is worse with Duolingo because if you have a google account associated with Duolingo, it requires you to log in with google. I can't use my password to log in, so I can't use Duolingo on Firefox

In order to reproduce:

1. Browse to klarna.com 2. click on [login] and then [login for customers] 3. page will redirect to https://app.klarna.com/login?market=de&utm_campaign=header-login-link&utm_medium=referral&utm_source=klarna 4. (you should have an account, if not just create one and proceed with following step) 5. click on [sign in] 6. enter email assigned with your account 7. click on [Confirm and Continue] 8. (a verification code is sent to the email or phone assigned with your account) 9. enter verification code 10. page will redirect to https://app.klarna.com/ and will show a frame where to adjust settings about how klarna will collect data by tracking technologies. 11. click on any button to close that frame (accept all / required settings only,...) ---> Does not work :-(

Hi all. I am having a strange issue with Discord. I can get notification sounds and all other media plays fine there. But whenever I try to "speak comment" or set the settings to always speak comments, nothing happens. The tab shows "playing", but no audio comes out, and nothing shows coming through on the mixer.

Chrome does speak as expected. A different computer, same version of Firefox also does speak as expected (in a different voice though). So that narrows it down to something in this particular copy of Firefox that is causing the problem. Plugins, settings and extensions on the two computers look the same. Also tried a different audio interface. If anyone has any ideas, please let me know!

Specs: Windows 10, Firefox 91.0 32 bit (both computers)

The last Firefox update made my website not work properly. I have dropdown menus that are no longer clickable or responsive to hovering on Firefox after the last update. Please check Gardenerd.com. It still works fine on Chrome, so I know it's not my website. It's Firefox. Please put it back so people can access my site content like before.
