Firefox Community Forum

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

I have noticed that since around Friday, April 24th, 2026, that Youtube videos will sometimes refuse to load properly. The page for the video will come up, but buttons on the page will not load, and nor will the video. This started happening around mid-day, when prior to it, things had been fine. At first I thought it might be tied into the 'ambient mode' option on Youtube itself., But even after shutting that off, I found it was still happening at ranodm.

Is this something new Yotube is doing in their continued (idiotic) fight against ad blockers, or is there an actual glitch in the browser or, more likely, a glitch in Youtube? Like I said, this seems to occur at random and I can't trace the cause for it. I'll include a screenshot of what I'm seeing. But if anyone knows what's happening here, I'd appreciate it.

I should add that I am on Windows 11 and using the new version 150.0 for Firefox. (Congrats on that, by the way.)

I'll be honest, I keep hearing some other browser can block youtube ads innately. (Brave, I think it was called?) and while the idea is cool, I'm not giving up a browser I've used for over 20 years for it. If Firefox can find a way to implement a similar means of blocking Youtube ads innately, I;d love it. But for now, I just wanna know what the devil is happening with the site. Can anyone help?

I cannot sign in to my banking website. I assume it's something to do with cookies or permissions. This is on my desktop, but I have no problem on my I-pad. I have the latest version of Firefox and I am using Windows 10.

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,

Hi, Firefox (PC or Mobile) can't load this web page ( https://www.keter.com/fr-fr/nous-contacter.html ), but Google Chrome or Microsfoft Edge can. Screenshot with Firefox and Chrome Just this form, i can browse the site without any problems. Any ideas? Thank you

I need my gmail account but I cannot sign into it, it wants me to start a new one, but that will not do at all. I will wait for a week to see if you can rectify this problem.

Using Firefox, 148.02, on windows 10, 22H2, 19045.6937. .I have a single page on Paypal that initially displays correctly then almost immediately becomes very large and shifts to the left. See attached image.

I see it correctly in Edge. Have tried minimizing and restore, reduced screen then restored, tried F11 full screen. No help. Tried various scaling and Firefox zoom settings. They don't help and every other page is distorted. This is the only page I have a problem with. It's got to be how that page sees Firefox. I've talked to Paypal support, they say they have no problem. Can't find anything on Mozilla/Firefox help

Google Chrome for PCs (Mozilla Firefox and Microsoft Edge will work, but you may encounter problems). I see that message way too much when getting notices from my doctors prior to connecting via Telemedicine. I have been using Firefox ever since Netscape Navigator closed up shop (in the 90's). So without question, I am a long time, dedicated Mozilla user. I'm sure you can imagine how frustrating it is, for a dedicated user like me, to see those sort of messages accompany the instruction for connecting with Telemedicine. They encourage everyone to use Chrome! What can be done to change the perception that they should use Chrome instead of Firefox? And how do we get the word out to the medical community (and others) that they can count on Firefox to give them a seamless experience when connecting to their patients (or others)? I just don't think we should surrender this position to Google Chrome. Best Regards, -Steve

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?

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

I am having issues using the search functions on car rental websites for National, Enterprise and Alamo car rentals. I enter in all the needed info for location and dates, but when I search, I get an error message that says try again later. See attached screenshot. I am using Firefox 150 and Windows 11. Other car rental sites work fine and I've never encountered this issue before.

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?

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!!

this has only happened recently. I've cleared the cache and closed the browser, but the Grok home page keeps crashing the tab and Firefox reports this. OI'm using Windows 10 and Firefox v147.0.4

My machine runs Windows 7 (will not change) and Firefox version 115.32.1esr (64-bit). Until a few days ago, weather.com worked as expected. However, when I try accessing it now (with a specific location), the screen indicates: Application error: a client-side exception has occurred while loading weather.com (see the browser console for more information).

The following is from the browser console: [Experiment] Fetch all: retry=false [Experiment] Fetch variants for user: Object { library: "experiment-js-client/1.16.2", language: "en-US", platform: "Web", os: "Firefox 131", device_model: "Windows", device_category: "desktop", referring_url: "", browser: "Firefox", landing_url: "https://weather.com/weather/tenday/l/Ann+Arbor+MI?canonicalCityId=3c1740550b2f113b86f9cd665770bcf3e3e1a34bf7ac0189a6e3d215540792e7", first_seen: "1770396676.778", … } Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://api.lab.amplitude.com/sdk/v2/vardata?v=0.

What the bleep is going on and how can this be resolved? Note that the site works just fine when using a Chrome-like browser.
