Firefox Community Forum

I have logged into TinyURL.com MANY times using Firefox. Now, I get a Cloudflare Validation Error when trying to do so (see attached screenshot/snip).

This was done in Troubleshooting mode, but is the same in standard mode, though I have no extensions enabled. I've tried turning Protection Tracking off; no luck. - We use ZoneAlarm, but the Web Secure functions are all disabled. - I have the same issue on 2 PC's, one Windows 10 and the other Windows 11, 64-bit. - I'm on FF release 150.0.2 - 64-bit, and both Windows installs are fully updated and kept that way. - I've reached out to TinyURL in hopes of resolving the issue. They suggested many of the above steps but not resolved this issue. - HOWEVER, I've found that login via Google Chrome IS seamless - no issues.

What is it with Firefox that it's having issues with the Cloudflare "Human" check? I've checked the Cloudflare site; all conditions are good, and this very setup passed the "Turnstile" check.

FF is my #1 preferred browser, so please look into this. I see that others have posted similar issues over multiple years here (but a search of support articles didn't find one . . .)

Thanks,

the problem started 2 or 3 updates ago. I keep hoping the latest update will fix the problem. I can still access using Chrome. I've tried clearing cache and turning off ETP

I can't login to reddit on desktop but I can on mobile.I disabled all the extensions I have, cleared the site data and cache, reloaded the page after each of the aforementioned and am still unable to login. I can login with no issues on mobile and chrome. Every tip I saw said to disable malware bytes guard, but, I do not have that extension. Any idea what could be causing the issues?

Greetings,

For the past three days (A/O 06/01/2026) I, (and others who have posted on various sites) cannot access a functioning log-in page for Google or Gmail via Firefox. If I (and others) use an alternate browser e.g., Edge, the log-in page functions and displays as it should. However, when using Firefox, the page displays as the image I've included - no functional 'log-in' icon and no Username or Password box. Using 'Private Viewing' makes no difference. As other browsers work, I will assume this is a Firefox issue. As there is no way to submit trouble tickets, I'll leave this here in hopes that someone from Firefox will pursue the issue.

Thank you in advance for any information or resolution.

Bonsoir, Je suis sous Windows 10 depuis son existence, toujours avec Microsoft Defender et mise à jour automatique de Firefox. Mais depuis quelques temps, le fond d'écran du site de ma banque société générale est mauve ??? Et je ne peux entrer aucune information. En appuyant sur la touche Echap, le fond d'écran redevient blanc, le site se débloque mais devient mauve et bloquant à chaque changement de page. Cela ne m'était jamais arrivé et je ne sais pas comment résoudre ce problème. J'ai contacté ma banque me disant n'y être pour rien et me conseillant d'utiliser un autre navigateur. J'ai essayé Chrome et Edge pour voir et effectivement RAS. Et cela n'arrive que sur ce site, vraiment étrange. Merci pour vos conseils Pascaline

After successfully using an AI image generation site (OpenArt.ai) for numerous months, I suddenly stopped being able to successfully upload images from my local hard drive into its image editor. All attempts created an "NetworkError when attempting to fetch resource (storage.googleapis.com)" error. I had made no changes to settings or permissions of any kind, but out of nowhere I cannot use function of that website through Firefox. Onlines searches suggested setting up a local network with Python, which is not something I'm familiar with, or that there were browser extensions identified as "Web Server for Chrome" the "Local File System" extensions, neither of which seemed to come up in browser extension searches through Firefox using those terms. Anybody got a fix easy enough to be walked through without learning new software?

Hello, https://www.so.energy/myaccount/usage shows a vertical bar chart representing electricity usage over time. If I hover the mouse pointer over one of the bars in the Edge browser I see a pop up that gives details of the electricity use represented by the bar. If I do the same in Firefox the bar changes colour to indicate it has been selected but there is no pop up. Is there likely to be a Firefox setting that is preventing the pop ups from showing? Alan.

I have no idea what is happening. Whenever I try to use youtube on firefox the site just freezes. I can still scroll up and down, but nothing that wasn't already loaded loads, I can't click on anything, and nothing except scrolling does anything.

The reload, home, and even screenshot buttons don't work in these frozen youtube tabs. The only way to do anything is to open a new tab and close the frozen youtube one.

Youtube is completely unusable because of this.

I turned off every single addon, I restarted firefox, I restarted the entire computer, I tried in a private tab. It still freezes every time.

I don't have a VPN, I do not have the problem on any other website (even other media-players), and I don't have a clue what is happening.

I do have youtube premium.

Any help would be appreciated. I need to watch stuff for my studies but I just can't

Operating system: Windows 11

Hi, I am using Firefox version 150.0.3 (64 bit). It says it is up to date and I'm on Windows 11and it is fully updated. I use the Colorado Peak website but can not upload documents to them or read my mail from them. I have to go to another browser to do that.

I have used Firefox as my default browser for over 20 years I don't want to give it up or use another browser even to do just a few things once in a while. Peak tech support says they have communicated with Firefox but gotten no response. Help!!

Hello,

These error messages can result from a compromised IP address which you can check here:

https://www.akamai.com/us/en/clientrep-lookup/ or here: https://dnschecker.org/ip-blacklist-checker.php?

However, this post is for the condition where these messages are received yet your IP address is clean.

I have two browsers installed Firefox and Chrome. Firefox has problems with an ever increasing number of websites (that are switching to Akamai Edgesuite) while Chrome marches on without issues.

I recently discovered the Browser User Agent identification string that is used by the server to determine what browser it is talking to. This is useful for serving content correctly to different types of devices like a phone or PC. You can find your Browser User Agent string here:

https://dnschecker.org/whats-my-ip-address.php

So thinking that this might be Firefox's problem I copied the string from my working Chrome installation and added it to Firefox. Unfortunately the issue continues.

So somehow Edgesuite is using something MORE than just the user agent string to kick Firefox to the curb. Does anyone have any clues as to what this might be and how to get Firefox in the good graces of Edgesuite?

Thanks, Steve

Today, for the first time, I could not login to my bank using my Swedish Bank-ID to identify myself. The ordinary QR-Code was no longer the same and was therefore not readable for my phone camera. Have there been any recent update of Firefox, which could explain this?

When trying to view a Fusion 360 model or a Sketchup 3D model, I get a message that WEBGL is not supported by my device. It has always worked in the past and still works under Opera and Chrome.

With all the background auto updates, it's hard to determine what changes have been made to my PC prior to it stopped working.

After searching for solutions and going through the checklist:- 1. My video (NVIDIA GeForce RTX 3080 Ti) drivers are up to date, 2. "Use hardware acceleration when available" is checked in Firefox. 3. "WEBGL.disabled" is set to false.

Is there some other tweak in Firefox that I'm missing? I'm assuming it's a Firefox issue/bug as it works in other browsers... just tested Edge... worked OK.

I'm running Windows 11 on a fairly high end PC which I believe is up to date. Last checked 12 hours ago.

Any suggestions would be appreciated... however, please consider that I'm just a dumb user and not a techo.

Since many years now, there are more and more Websites which don't work properly under Mozilla. Each time I write to the Webmaster, I receive this answer. We have not optimized your website for Mozilla Firefox, whose technology is outdated.

Many websites don't display interactive maps in Mozilla.

I understand that Mozilla has a very good system for protecting personal data and prevents sites from tracking users. I also understand that Mozilla allows for efficient cookie deletion, which commercial companies probably don't appreciate. Is this the only reason why so many companies don't want to optimize their websites for Mozilla?

To display this page, Firefox must send information that will repeat any action (such as a search or order confirmation) that was performed earlier.

Why am I getting this warning? I am unable to login.

If I go to AOL.com they useually have 40 or so news articlaes/ads you scroll through. Several weeks ago the text for the articles stopped displaying. I have tried other browsers and the text shows up. Not sure what setting may effectr this.,

Firefox is not able to log into Amazon, while Edge is OK, I know that a lot of Windows 10 updates have been installed of late plus other changes I am unable to work out whats wrong .......Help
