• The attached image shows Firefox (on the right) not displaying Helvetica correctly. It appears jagged and not pleasant to look at. The browser on the left is Edge and all Chromium based web browsers seem to render it as it should.
• I've tried to look into (about:preferences#general) and the option that says (Allow pages to choose their own fonts, instead of your selections above) is ticked.
• I've also tried reinstalling the browser, clearing the website cache and also, removing my profile from it. None of these seemed to fix the issue.
• It's been persistent for quite some time now, however I didn't really find any articles regarding this issue.

  Any help would be greatly appreciated!

Expected: Firefox displaying all known Unicode characters.

Result: Many characters missing.

Failure page as an example: https://en.wikipedia.org/wiki/Religious_and_political_symbols_in_Unicode

Description: I tried going through a Unicode list Unicode list and the extensive set of characters displayed correctly. However, when reaching further into character sets as shown in the failure page page, many are missing which are not new.

• "Repair encoding. . ." button was not active.
• An encoding switch extension was not able to resolve the issue.
• Troubleshooting mode did not show changes.
• Switched fronts available such as Noto Sans and Roboto Sans without success. Possibly a font failure?

None of the menu buttons work at the top of yahoo mail in firefox when an e-mail is open, I am able to use these in Microsoft Edge. Until the last update of firefox they worked so something broke in the latest release 103.0.1 is my guess. I restarted without extensions and still broken.

I am getting Access Denied on many web sites that i have used frequently. For example, for the site https://www.apartments.com/ I get this message:

Access Denied You don't have permission to access "http://www.apartments.com/" on this server.

Reference #18.ca68dc17.1653685076.c42d150

I am using Firefox Browser 100.0.2

Help!

Lately in Google Drive I get this error when I select one image or a file: Impossible load details. Retry. I have Firefox 108 version, on Edge and Chrome all is OK. Also the troubleshoot mode doesn't resolve the problem.

Hi,

I use Firefox daily, but since the last update I'm unable to make card payments on websites and I'm having to use Chrome as a backup. Up until the update everything was fine and there were no issues making payments on the Royal Mail and Asda websites. When I click the pay button on these sites, the payment window does not open up.

I've tried disabling all addons/extensions to no avail.

Regards Andrew

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.

Getting unreadable text when website is using a font that isn't installed (see attached screenshot). When I view the source in developer tools it uses Roboto (which I haven't installed).

On my Mac, I have tried other browsers (Chrome and Safari) and they work fine. I have also tried this website with Firefox on Windows and it also works fine.

When a playlist is loaded and played on YouTube, the next video in the playlist should automatically start playing once the current video reaches its end. This feature is commonly known as autoplay. However, I couldn't get it to work consistently. When the current video is finished, next video is loaded normally but where it should automatically play it doesn't.

I have tried below to address this issue:

• Autoplay next video works in safe mode.
• "allow audio and video" in autoplay permissions in https://support.mozilla.org/en-US/kb/block-autoplay doesn't help
• I have also set media.block-autoplay-until-in-foreground preference to false in about:config but didn't help
• I have tried uninstalling all extensions and it didn't help
• Tried logging out of youtube, but this didn't seem to help with the issue.
• Tried "Clear startup cache" in "more troubleshooting information" menu, didn't help
• Tried "Refresh Firefox" which didn't help

Thank you.

When I open "Wheel of Fortune" and click on "Log-in", nothing happens. I am unable to log-in. Using another browser, I have no problem.

Anyone with a suggestion or solution for me?

Hi all, is expired cookies management changed lately? Authentication doesn't work anymore in following use case. Question is all about FF for windows, while usually I'm on FF Android, Edge and Chrome for Windows and all these browsers are working correctly.

My working web app (static blazor wasm standalone) is interactively authenticating in Azure AD B2C using Microsoft.Authentication.WebAssembly.Msal library (like MSAL.js), API is an Azure Function protected through AAD B2C.

Login request successfully invokes Signin/Signup B2C flow with popup to myb2ctenant.b2clogin.com but breaks navigating to auth protected pages or backend apis.

From DevTools I see that every request to following b2c endpoints sets an expired cookie (expired 10 years before, year is now 2012):

When user clicks login: GET /myb2ctenant.onmicrosoft.com/b2c_1_sinsup/v2.0/.well-known/openid-configuration

Returning from login confirmation: GET /myb2ctenant.onmicrosoft.com/B2C_1_SInSUp/api/CombinedSigninAndSignup/confirmed?rememberMe=false&csrf_token=xxx

for example: Set-Cookie: x-ms-cpim-trans=; domain=myb2ctenant.b2clogin.com; expires=Fri, 14-Sep-2012 12:46:46 GMT; path=/; SameSite=None; secure; HttpOnly

FF registers this warning in console:

Cookie “x-ms-cpim-trans” has been rejected because it is already expired

Following when MSAL execute a request to /myb2ctenant.onmicrosoft.com/b2c_1_sinsup/oauth2/v2.0/authorize?xxxx

Response always contains:

Location: https://blazorapp.xx.web.core.windows.net/authentication/login-callback#error= interaction_required&error_description=AADB2C90077%3a+User+does+not+have+an+existing+session+and+request+prompt+parameter+has+a+value+of+%27None%27.%0d%0a

All other browsers are working... Thanks in advance for any help

Hello. On some of my sites that i try to get onto with Firefox its says performing TLS handshake then it goes to Secure Connection Failed and says PR_End_Of_File_Error. I am totally updated with Firefox, plus i cleared out everything in my history. That did not help. When i tried to get onto these websites with Chrome web browser i do not have this problem at all. Why is this? I have BitDefender Total Security newest version for home. My firewall is through them along with virus protections. So can you help me out with this ongoing problem getting on some websites?

Thanks Firefox [email removed from public]

I've been watching and following along with a Unreal Engine 4 Course on Youtube for some time now (mentioning in case the resource usage has something to do with it), and in the past couple days I've noticed a pretty serious and annoying bug. When I pause the video, tab (Cmd + Tab on MacOS) into Unreal Engine, do some things, then tab back and resume the video, it will play for one frame and then stop and buffer, but the audio will continue playing. The only way to get the video to resume is to skip forward/backward in the video (either with the arrow keys or the progress bar). I've also tried Troubleshooting/Safe mode and the issue still persits.

Not exactly sure when it started, but youtube shorts are broken in Firefox now.

You can scroll to the next video fine, but if you continue to scroll to the next after that (3rd consecutive video) you get redirected to the first video you started with.

I did try to restart FF in Safemode, but no change. In other browsers (Chrome, Edge) its still working.

Since yesterday (Sep 26 2023), Twitch.tv has been having multiple issues related to basic functionality of the website, and this has happened before but I did not report it because I was able to fix it. I can not purchase or use bits despite Twitch having a stored payment method on file that I have confirmed has sufficient funds, I can not subscribe or gift subscriptions despite Twitch having that same sufficiently funded payment method on file, I can not redeem or earn channel points, I can not send or receive Twitch Whispers (a form of DM), I can not follow or unfollow channels, and I am convinced that if I was to log out, I would not be able to log back in. I can chat in stream chat, and I can watch streams, that's all I can do. But I enjoy using the other features that are currently blocked, I am over 18, and I am the only person that uses this computer, so there should be no parental controls problems either. Yesterday, I restarted my browser, which did NOT alert me that it had updated, and all of this functionality was broken. Roughly 6 months ago I was having the exact same issues, but I was able to fix it by disabling many of the anti-tracking protections on my browser (had to disable them universally except for blocking cryptominers, not just with the shield icon). However, now, even with those settings unchanged, roughly 75% of the features of the website Twitch.tv are nonfunctional. I have included a cropped screenshot of me attempting to redeem something using channel points, the purple box is the button, and the spinner icon stays there for over a minute with nothing happening, which is not how that is supposed to work.

I enjoy watching streams and interacting with people on Twitch.tv, and I wish to continue doing so in the way I am accustomed to. However, it would appear that Firefox has other plans. If this continues, I will be forced to switch to a less secure browser for specifically that site, which is an idea I do not look forward to.

When I use a vpn with firefox (not the firefox vpn), I cannot open normally blocked websites such as twitter or youtube, and instead they open in a sort of half-loaded state (see image). I don't face this problem with other browsers. I have tried deleting and reinstalling firefox, but it doesn't seem to work. Can anyone help out?

Since a couple of months I see only [object Object] instead of code blocks on (almost) all web pages. For example on StackOverflow.

Any ideas what could cause this?

Radio buttons on some websites neither display nor update when the area in which is should have displaed is clicked. FireFox 113.0.2 (64-bit) on Mac OS X 10.13.6 (High Sierra). This problem has been present for some time. On other websites the radio buttons do display and do upate when clicked by toggling the dark center. The minority of websites which don't work seems random, but does include some banking websites and the IRS.gov website. Often using SAFARI will work when FireFox doesn't.

The CheckBox at the end of this page "Email me when someone answers the thread" appears but does not respond to a click.

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.

Hello guys,

I just got a new M2 SSD and I just decided to reinstall Windows and everything on it. However, when I installed Firefox I started getting this exact error message on all twitch streams: "Your browser encountered an error while decoding the video. (Error #3000):. Keep in mind I have tried most if not every "fix" I've found. I've disabled the hardware acceleration, cleared cookies and cache, I've disabled the extensions, I've tried Incognito mode, I do not have a third-party anti-virus and I do not have a VPN. This works on all other browsers and it used to work on Firefox before I wiped my PC, so that I can install Windows again. I really do not want to use a different browser, I love everything about Firefox right now.

Any suggestions will do, thank you very much.
