Firefox Support Forum

I'm trying to use Microsoft Teams in Firefox because the native app for Linux is abandoned and crashes, and at first sight the app is blocking Firefox on purpose. Buttons to make calls are disabled, stating that audio and video are not supported in my browser, but everything works normally if join to existing calls using e.g. links.

Is it possible to trick Teams to think I'm using Chrome? I found the "User-Agent Switcher and Manager" add-on, but I can't figure out how to possibly use it.

Hi! I was wondering why nearly every single page these days opens to the message :

"400 Bad Request Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit. Apache Server at canvas.instructure.com Port 80"

Nearly every link I click on a website refuses to open! It has become impossible to do school work on this browser because I can't open any link on my school website, and nearly every website struggles to open except from google. I know the links work because I copy/paste them into Google Chrome and they open immediately. Truth be told I prefer Firefox and would much rather keep using this browser! I also can't find an update for Firefox so I believe my Browser is up to date (and I know my laptop is up to date and virus free). Is there a fix coming soon? Or a setting I can change to be able to open links? Classes start this week and I'm stuck!

Thanks for your help!

I use Firefox on a PC to access Facebook (website, not app). This week the Messenger/Chat feature stopped working. I click the icon and it opens but nothing appears in the box, it just hangs. There is an option to open in its own window, but that also is blank - no past messages, no contact names, no ability to start new message. When I log onto Facebook in Edge, Messenger works fine in Facebook.

I've tried everything I found on the internet for this issue - updated and refreshed Firefox, cleared history/cache/cookies/site data, uninstalled and reinstalled Messenger, refreshed Facebook to initial settings, used Firefox in troubleshooting mode, reset everything, turned off browser, turned off my computer, used shift key to reload tab - nothing has worked. There are some instructions about stuck cookies, but I didn't understand them so I didn't try that one thing. I've gone into every menu I can find to try to figure out this issue, which isn't the end of the world, but I would appreciate some other ideas for what is suddenly causing this. Because now I have to redo all of my settings and preferences and logins and the problem still isn't fixed.

Hello everyone,

I need help because on Firefox ESR that runs on Debian some css appears really too big. In this example I will show the difference between Firefox and Chrome. If I open this popup from Firefox it appears full width. In Chrome it appears correct. Also I noticed some Icons rendering incorrect.

How can I achieve this? Thannks

I am trying to set up a Shopify page. It was working fine until today. The page is now redirecting me to the sign in page every time I attempt an action. Shopify support says that they were able to perform these actions on my account from their end. Also, I was able to complete the tasks from Microsoft Edge. Any suggestions.

Vs 117.0, installed this morning, will not "continue to spotify", during the login process to the spotify desktop app. All had been working perfectly over the past few months until today. Was able to connect to spotify thru Chrome, but something get changed/broke in the new firefox v117.0 (64 bit), Win 10.

Using Firefox today I tried to search for various things using https://oceanhero.today/search.. I got this error message:

"Sorry, there was an error when rendering your search. We were notified and will try to resolve this issue as soon as possible."

But the search engine - which I've been using on Firefox for a long time without any problems - works fine on Bing.

Is there a remedy? Many thanks for any advice.

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?

When I copy text from other websites, I'm not able to paste in the text field of Whatsapp Web. I'm using Firefox Developer Edition Browser in my laptop. But when I copy text from Whatsapp Web itself, I am able to paste in the text field.

This issue started happening just a few days ago.

Here are my specifications:

Browser: Firefox Developer Edition 117.0b8 (64-bit)

OS: Pop!_OS 21.10

Reposting from https://discourse.mozilla.org/t/firefox-upgrade-from-115-116-results-in-broken-screen-capture/121964

Howdy folks!

I am on Arch Linux and recently upgraded Firefox from 115 to 116 and this broke WebRTC screen capture. Whenever I try to share my screen in Microsoft teams and Google Meet, the participants only see a black screen with a cursor. I am able to reproduce the issue on this test page. I had to downgrade to 115 in order to “fix” this critical feature. Before that it was broken in 114 and I had to use Chromium for presentations. I no longer want to touch Chrome with a 100 ft pole since they are trying to introduce Web Environment Integrity.

The only bug I have been able to find is from three years ago:

https://bugzilla.mozilla.org/show_bug.cgi?id=1640771

I don’t want to add a “me too” comment, but was wondering how to show/give my support to get this issue fixed? It is crippling to my work workflow, and I don’t want to be on 115 forever. I am an engineer so I can provide advanced support to a Firefox dev, just not development as firefox is gargantuan beast of a code base.

Any guidance or pointers would be appreciated, Thanks!

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!

Using MX-21.3_ahs_x64 Wildflower. Since upgrading Firefox to version 116.0.3 all links within www.onlinetvrecorder.com do not work anymore. No messages, no hints what happened, just not working. Vivaldi has the same problem, Chrome works. I have asked in mozillazine, but did not get an answer.

On Google Docs, the very useful shortcut "Alt+/" for executing menu actions by name exists, similar M-x in Emacs or Ctrl+Shift+A in PyCharm or Ctrl+Shift+P in VS Code.

On a German keyboard, there is no "/" key. In Chrome the hotkey "Alt+#" works instead. In Firefox, it does not.

This hotkey is particularly important, because it gives quick access to menu actions, that have no hotkey assigned, or for which the hotkey does not work on the current layout.

Is there something I can do to make it work?

Note. Based on what I know, I cannot tell if this is an issue with Firefox not sending the Alt+# key correctly, a special feature of Chrome that isn't present in Firefox, or a cross-browser compatibility issue of Google Docs, that should be blamed on Google Docs and not Firefox.

Firefox 114.0.2 (64-bit), running on Open Suse 15.3, 64 bit.

Hi, I have tried to create a google account two times. Each time Firefox didn't save the google account name.

Firefox did save the password though. Just the username is empty. So, the third time I will write down the username.

I know how to create a Google account. Pretty sure it will work. My question is, why is this happening? Am I paranoid thinking Google doesn't like to support Firefox?

Best regards

For some reason every type of embedded video, youtube, webms, etc, all show up washed out in white. This only happens in FF and I have tried a few ways to fix, but no luck. Any ideas?

Thanks.

link from a message to me in my email. Can't sign in . Keeps asking me to register and rejects my registered name. For the last couple years, intermittently.

I am running the latest FF on Fedora and few weeks ago I started having this issue where some images aooear scrambled. Pics attached but for example the QR code on messages.google.com looks scrambled. Same for some favicons, some of the iconography on Google maps, and random others.

So far, I've tried disabling VPN and all add-ons (Troubleshoot mode) to no avail. Can't seem to find a pattern, it seemingly happens at random. Any suggestions appreciated.
