Firefox Support Forum

• 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!

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 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.

Hello, This issue might or might not be related to [other issue] I have since I updated Ubuntu 20.04 to 22.04 and therefore updated my Firefox to 104. I can't login anymore on Letterboxd since the update. It's not a problem of username or password. When I click "Sign in", nothing happens except a page refresh, but I'm still not logged in. Other strange behaviour on that site since the update: most of the images don't appear. For example on this page : https://letterboxd.com/films/# all the movie covers are just blank.

The website does work properly when using Firefox in private mode though (both login and images work fine), so this makes me think it's related to my other issue mentioned above.

OS: Ubuntu 22.04 Firefox 104.0.2

EDIT after posting this question: I just found out that I can't login on Google either. I enter my username, password, then it asks me to validate on another apparel that it's really me, which I do, and nothing happens so I can't login. It works normally in private mode.

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?

i can't play some (but not all) youtube videos. they do play on other web browsers.

the message is "an error occured, please try again later. playback ID is ... " 

i'm using firefox 106.0.3 on linux suse tumbleweed. Before I upgraded to both of these the same videos were playing ok.

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?

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.

This site, Costco Instacart, worked perfectly with Firefox as recently as April 15, 2023 but today fails (see attached image): https://sameday.costco.com/store/costco/storefront?zipcode=11021

Cloudflare believes it is protecting itself from online attacks when accessed by Firefox. The same site worked perfectly today, on the same computer, using Google Chrome.

Cloudflare is a major CDN and many important commercial sites, like Costco Instacart, have their content delivered by Cloudflare so this is a major issue with Firefox. For the moment there is a work-around, use Chrome instead, but it would be better to have Firefox address issues with Cloudflare.

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?

Since upgrading to Monterey, Google search pages show almost no text in Firefox. Google searches in Safari and Google Chrome are completely fine. Only Firefox is showing the problem. The blank text includes dropdown menus too - all options inside them are blank. Currently on Firefox v107.0, but the same problem happens with older versions.

If I go into Troubleshoot mode, the Google searches are working fine. I have refreshed Firefox, Cleared the startup cache. But the problem persists. I uninstalled Firefox from the machine, restarted the computer. Did a fresh download and install, haven't signed in so there are no addons/extensions to cause problems.

This is happening on both an Intel Mac and an M1 Mac running Mac OS 12.6 Monterey.

I attach one screenshot showing the same page with and without troubleshoot mode on. The second screenshot shows another page of results including what looks like weirdly encoded characters.

I've followed all the suggestions in the support page but nothing has helped. I'd really appreciate any advice on further troubleshooting. Thanks in advance for any help.

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

The layout on the Roblox website, https://www.roblox.com Has appeared to break, I've seen the website on Google chrome and Microsoft Edge and it's good to go. I am not aware as to how this has happened. I have disabled every Addon I have, This issue is not caused by the Addons I have installed.

CTRL + F5 has Fixed My Issue! Thank You cor-el!

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?

Hello,

this problem started happening around 3 or 4 days ago.

Usually, at the end of the day or before I close Firefox, I "delete browsing history" BUT only the "today" history. I know it's a weird habit (lol), but at least it logs me out of all recent browsing while keeping my sessions with older websites active (typically these older websites include stuff that I use frequently like Outlook, Google/Youtube, Twitter & other social media, Spotify, and a few other sites).

The other reason I do this is that I like my "recent history" to be ordered the way I like, so I can use it kind of like a "bookmark list".

The problem: Since about 4 days ago, each time I "delete history", ALL my accounts are signed out. Note that I don't have the option to delete cookies upon closing checked, and whenever I close Firefox without deleting history the sessions appear to be active.

I think 3 or 4 days ago there was a Firefox update? I remember at the time I was shown the extra tab with the release notes, but I didn't pay much attention. However when I noticed the issue, which was the day after, I assumed it was a new feature of the update that caused all these websites not to recognise my browser and thus ask me to log in again.

So just before going to bed, I tried 1) clearing my history for the day as I usually do, except 2) instead of closing directly after, I would go to the sites I want to remain logged in (in this case I just did Outlook, Youtube, Twitter, Facebook, Tiktok and Spotify), log into my accounts, and then close the browser.

So the following day, it worked "as usual"... almost... that is because when I deleted my history of the day, it logged me out of everything again. But in the "recent history" list, it showed the updated list (with the websites I re-logged into the day before).

So I can't guess what is happening, other that something is messing with my cookies each time I delete history. I even went to check manually to see if I still had the session cookies stored in Firefox and it appears to be the case.

Yesterday I also tried logging into a Google, waiting a few hours, and only deleting the history of the past hour, but the same thing happens, I instantly get logged out.

Additional info: when I "delete history" I only check the first five options (those under history) and not the lower two (under data).

Thanks for your help, and sorry for my English !

On a couple of websites, but in particular Rogers.com, the captcha just never ends. It asks to click on all the bicycles, I click on them one at a time until no more appear, hit verify, it brings up something else. It will do this dozens of times and just never ever end.

Switch over to Edge, does the same. Switched to chrome and it works fine. Has google done something to captcha to deny it working on other browsers?

I have checked to see firefox is up to date and it is. I have disabled all extensions/addons. I have run malware/virus scans. On the Rogers community forums there are all kinds of people having problems but there are no solutions on how to fix. Oddly (or not) the problems are similar...captcha won't work on Edge, Firefox but will work on Chrome.

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.

For the past few days I get the request to enter captcha characters every time I try to access the Amazon website using Firefox on my Win10 PC. It works fine on my Firefox for android on my phone and also works fine using the Edge browser on this PC.

I've tried resetting Firefox. I've tried troubleshooting mode. I've tried turning off enhanced tracking. What else could cause Amazon.com to feel the need to verify that I am not a robot ?

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?
