I'm unable to access GroupOn from my laptop while using FireFox browser. When I attempt to log on using my Email user name, a message that states "ACCESS DENIED" appears. I have followed the steps to clear the cache but doesn't correct this issue. I'm able to access using my email user name using an alternative browser but I prefer FireFox. Currently running Windows 10. I receive emails from GroupOn using the same account that I attempt to log on with and receive the "ACCESS DENIED" response. Any knowledge would be appreciated

Hello, I am trying to login to my account on www.zazzle.com and use their site. Sometimes it will let me through and I can be on the site for about 20 minutes before a captcha comes up that says press and hold this button so we know you are not a bot. Well the button never works, it always errs out and gives me the message to please try again, and then locks me out of their site. I have tried clearing my cache and cookies, updating my browser, resetting the router, I don't have any VPN's, I have tried working in a private window, adding the website to the privacy exceptions, block pop up windows is unchecked, I am out of ideas, what do I do??

I'm get an Access Denied for a web-site I have frequently accessed. Only Firefox on my laptop has this issue. Edge and Chrome are able to access the web site. Firefox gives me the following error:

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

Websites such as the Sites above are not working in Firefox or other Open Source Browsers. I am being forced to use Chromium in this case to complete payments and add items to the DMV Cart and complete a payment for example. I do not want to have to do this. I do not want to be forced to use a Closed Source Browser such as Microsoft Edge or Google Chrome or Apple Safari. Or, Even the Open Source version of Google Chrome Chromium. Companies like PGE are deciding to drop support for Firefox as the State not enough users use Firefox. They are forcing the market to use a Non Open Source Browser. This is a Problem. This is not good for Competition and the Internet as a whole. Not good for me as I am a Linux User. The PG&E website does not even load when using Firefox. The DMV site loads but does not allow one to complete any Payments for Example. At this time one can only view Information on the DMV website.

Hello,

Since the latest update of Firefox (version 135.0.1) when writing an e-mail the lines keep dropping down automatically at random intervals.

The e-mail host we are using is Polaris Mail, which is through our website provider.

To make sure it wasn't an issue with polaris mail, i have logged into our emails through microsoft edge and they have worked perfectly fine.

I have attached a picture for reference.

Kind regards

I can not get Youtube to load on desktop Firefox. It works fine on the mobile website, app, and Chrome. I've tried clearing cookies and site data, removing extensions, resetting Firefox, and disabling hardware acceleration, and so far nothing has worked. Has this been happening to anyone else ?

Hi! I'm experiencing an issue where videos on YouTube stutter or play choppily when using Firefox. This happens even when the internet connection is strong and works fine in other browsers like Chrome.

Here’s what I’ve noticed:

The issue occurs on both 720p and 1080p videos.

It’s more noticeable when switching to full-screen mode.

I’ve tried disabling hardware acceleration, but it didn’t help.

Firefox is up to date (v126.0).

I’m using Windows 11 and have an NVIDIA GPU with the latest drivers.

I’d appreciate any suggestions or fixes. Thanks in advance for your help!

Hi.

I've been having this problem for a few months now with Firefox displaying the message "Hmm. We’re having trouble finding that site".

It's intermittent and not related to a particular site.

Usually, if I click "Try Again", the page loads perfectly. Sometimes, a second attempt is required.

I'm having the problem with 2 of our desktop PCs (different profiles).

It got so frustrating I switched to Brave for a while. It doesn't have the same problem.

I'm just guessing here, but I've noticed that some sites (again, no particular sites, it varies) take 10s-15s to come up. Is Firefox giving up and reporting "Server not Found" while Brave keeps trying?

The computers are rebooted daily and I've tried cycling the power on our router.

No other responses to this problem have helped.

Hi everyone.

This could be related to the corrupted file I had that was solved here: https://support.mozilla.org/en-US/questions/1492585

I mean something else could have been corrupted. I've been getting the following error on a website:

> "The site at [url] has experienced a network protocol violation that cannot be repaired. > > "The page you are trying to view cannot be shown because an error in the data transmission was detected."

I thought it was a website issue. But it worked fine in Edge.

I tried the Ctrl+F5 but nothing changed (also tested the website in private browsing in both FF and Edge; still works fine in Edge).

Thanks!

Edit: I launched the factory settings profile from about:profiles (last used years ago when I moved my main profile from an older PC) as a test and the issue persists.

Hello, I’m experiencing an issue where my website https://smartstartkids.com.ua doesn’t load at all in Firefox. When I try to open it, nothing happens or I get a message like “The connection was reset” or “Network error”.

The strange thing is that it works perfectly in Chrome and Microsoft Edge on the same devices and network.

Here’s what I’ve already tried: • Cleared Firefox cache and cookies • Created a new Firefox profile using firefox.exe -P • Disabled and fully uninstalled ESET antivirus • Turned off Windows Firewall • Reset DNS and Winsock via Command Prompt (ipconfig /flushdns, netsh winsock reset) • Checked proxy settings (set to “No proxy”) • Tried with HTTP3 disabled (network.http.http3.enabled = false) • Tried from two different PCs and networks — same result • The certificate shown is from “Sectigo”, not ESET, so it seems to be correct now

Still, Firefox is the only browser where this specific site doesn’t load. I’d appreciate any ideas or help!

Thank you!

I used to have an occasional sound problem with FF, usually felt when YT clips could not be heard any more. I mean to remember that it could be fixed (until next time) by restarting the file explorer somewhere in Task Manager - not a convincing solution but one I could live with.

Today, there's a new situation. Again, trigger was the missing YT sound in FF - not in fx Edge, and that the Task Manager trick didn't work (or maybe I restarted the file manager in the wrong tab?). Looking for a solution, I happened to see that the YT mute function in the FF tabs seems to be gone. However, other sounds are affected likewise. Also, I can't see them in Edge either. After various restarts (or maybe something else I did, instigated by the various instructions I found?), the sound is back.

However, while continuing to pursue possible solutions, I also happened to find that my browser is being 'administered by my organisation' - what ever that means (see two annexes). Who did that? I would say, this is not something I did, I would prefer to see it gone. But how? Will the other browsers (which I keep as a spare, and that I'm hardly familiar with) be likewise affected?

This is an equation with too many unknowns for my limited knowledge, are such effects known? Would there be an approved way-out for it?

PS I have checked https://support.mozilla.org/bm/questions/1412934 especially the message posted by lazizakhmedov1014, and do not see this to apply to me - short of a reinstall - FYI

Recently I have had several experiences with captcha when paying for something with a credit card. I check the box saying I'm not a robot, get a green arrow, but then the purchase does not go through. Error message says I failed to satisfy the captcha, even though I was never shown the grid of images. Just now I tried the same operation with the same company invoice using Chrome, and it went through successfully by just checking the box I'm not a robot. This is very inconvenient.

When I'm on the Guide page, the option to change the guide to later in the day is not visible until i reduce the page to 90%.

However, when you try to advance the time, it does not work. Is shifts momentarily to the next time period, but immediately reverts back.

It works properly in Chrome.

Hi!

Yesterday, April 5, 2025, my Firefox started displaying this message for every search typed in the browser:

"Our systems have detected unusual traffic on your computer network. This page verifies that it is really you, and not a robot, sending the requests. Why did this happen?"

I tried a few solutions: I cleared the cache, restored Firefox, reinstalled Firefox, restarted the internet modem, reset the computer's DNS using the ipconfig/flushdns command, scanned for malware with Windows Defender, and scanned for viruses and malware with Kaspersky, but the problem persists, both in the normal tab and in the private tab.

I contacted my internet provider, and they said there is no problem on their side.

In Firefox, I always use the default search engine "Google".

When I change the search engine to "Bing", the problem does not occur.

The problem does not occur in the Google Chrome browser, only in Firefox.

I am using Firefox 115.22.0esr (64-bit), Windows 7 operating system and internet connection via network cable. I only have one computer connected and I don't use VPN.

Please, can you help me?

Thank you!

I have loaded Messenger onto my new computer as well as Firefox. When I go to Messenger the Voice and Video icons at the top right are greyed and when hovering over the icons, I get a message that video calling etc is not supported. i had no trouble on my other computer but am not sure how to activate the video and voice options. Can you please help me solve this issue. Thank you

When trying to access the Tax Withholding Estimate at IRS: https://apps.irs.gov/app/tax-withholding-estimator it will not work in Firefox. I get this message: "Application error: a client-side exception has occurred (see the browser console for more information)." I don't understand how to interpret the console messages.

I get the message after filling out the "Information about you" page and clicking NEXT. Website works without issue in Google Chrome.

Is there a setting I have clicked in Firefox that is breaking the website or is the website to blame?

Using Firefox 128.6.0esr with no extensions installed.
