Firefox Community Forum

Hello.

For the past few months, I've been experiencing severe issues with performance that I noted appear only on YouTube. I have not noticed this on any other website. The site is unresponsive, takes a long time to load, key presses (pause, skip 10s, etc.) are registered with a massive delay. It is generally very unpleasant to use.

I have tried disabling all extensions, clearing data, I even reinstalled the entire operating system once for a different reason and the issue still persisted. I launched YouTube on different browsers (Chrome) with no performance issues at all.

I lived with this problem for a long time now, but recently it's becoming unbearable. I prefer Firefox to Chromium-based browsers, but as YouTube is a site I visit very frequently, I will unfortunately consider switching to another browser.

I have not found any useful resources regarding this issue on the Internet, it seems like it's not a common problem.

Any help is appreciated.

Hello

When attempting to pay for online purchases the new firefox upgrade (Mac 133.0.3) will not redirect from the merchant to the payment site. Yesterday, before the upgrade, was no problem making credit card purchases online; now, nothing. Please advise on how to set up new firefox version to allow redirect to payment websites from merchant sites.

Thank you.

I use linux mint older version, with firefox latest versions. A problem has been developing where after clicking a search link, a page pops up warning of possible phishing site. usually i clicked proceed and was taken to the website, but now am taken to a blank page or 404"cannot be found." Of course the page exists but i cannot get there. the url is a smartredirect.de... always. How do I get rid of this redirect app?

Hi There. Please can someone try to help me..

I know VERY little about computers. I have windows 8.1 and firefox. All works perfectly and always has.

I do NOT have any other "devices" I am disabled and cannot use a telephone so do not have one, well, only the old sort i use to get one time passcodes.

In the last few days, everytime i have had to make a payment to anywhere, i have had the onetime passcode "authentification" thingy pop up from Mastercard. Not a problem, works perfectly.

Enter virgin media..

When i try to pay their bill, the "authentification" thing does not load properly and hence it is impossible to proceed. Virgin media are worse than useless and insist it is something wrong with my computer. If that is the case, why does every other website on the entire internet work properly then, apart from theirs..

I have added a screen shot of their web page..

If i refresh it, a different screen comes up, i have added a screen shot of that too..

Anyone got any ideas??

Thank you.. john.

FF 133.0.3 (64bit) OSX 13.6 Ventura

Am having trouble reliably accessing any site that uses Cloudflare.

No extensions are installed, no UA switching.

Have tried:

• Default settings as well as purposefully turning various settings "off", both with existing and brand new profiles.
• Disabling "Enhanced tracking protection", but it does appears to be hard-coded "on" as it appears as "Enabled" when any new site is visited, even even though about:protections clearly states "Enhanced Tracking Protection: OFF".
• Multiple DNS providers (Google -> 8.8.8.8, 8.8.4.4), (OpenDNS -> 208.67.222.222, 208.67.220.220), (Cloudflare -> 1.1.1.1, 1.0.0.1)

The issue with Cloudflare is getting past its endless "Verify you are human" turnstyle checkbox. As stated above ETP is supposedly "off". Even went ahead and added "https://cloudflare.com" and "https://challenges.cloudflare.com" to the ETP exceptions list (which should be unneccesary as ETP is supposedly "off").

Though this ticket was a few years old, followed all steps from https://support.mozilla.org/bm/questions/1273784 to no effect.

Double-checked:

Settings -> Privacy and Security: ETP -> Custom -> ALL unchecked (cookies, Tracking Content, Cryptominers, Known fingerprinters, Suspected fingerprinters) DNS over HTTPS -> Off

about:config: network.cookie.cookieBehavior -> 0 privacy.socialtracking.block_cookies.enabled => false privacy.trackingprotection.enabled privacy.trackingprotection.pbmode.enabled privacy.trackingprotection.cryptomining.enabled privacy.trackingprotection.fingerprinting.enabled

Going to any site and clicking the protection "Heart" icon still shows enhanced tracking protection to be "Enabled" (though it should not be). On any Cloudflare site, selecting "Disabled" immediately brings up the "Verify you are human" checkbox ad infinitum.

Just for fun, inspected a page a couple of times (the new serenity.ai search engine), clearing cookies & cache each time, noting the network tab via inspect. The only thing that appeared to change was the value of a cookie, and cloudflare's Ray ID. Two responses were in error, a 403 and a 401:

Had also reported this issue over at Cloudflare a while back; they were not very forthcoming as to why this behavior might be occurring. Often their own forum would get the endless turnstyle with FF.

Other browsers do not have this issue, and while I very much like Firefox, in recent releases it has become all but unusable where Cloudflare is concerned.

Please advise how to reliable get past Cloudflare's endless "Verify you are human" turnstyle.

Thanks!

Bonsoir, Depuis quelques temps Firefox bug quand je suis sur canal plus ce que je n ai pas avec google Pouvez vous me dire pourquoi ou réparer le problème Merci Chantal BREDEL

the browser is to laggy and i think there is something wrong, I reset it, removed and reinstalled would cause be the cause of that knowing I don't that face that issue on other browsers

Hi,

I have been having this issue with Firefow & Youtube for some weeks now.

What happens is that I launch a video, it plays well, but after 1 minute it stops. No buffering, no download of the next chunk of the video, nothing. It just stops. I have disabled all the addons I use and it changes nothing; in some cases, it stops the video from launching.

> Why this is not network related : on the same computer, at the same time, I can watch YT videos on Opera. Without issues. With uBlock origin enabled. And VPN. > Why I believe this is browser (ie. not computer) related : I have another computer, on the same network, that has the exact same issue. With less extensions, and no VPN. And again, when using Opera, YT works as intended, with uBlock origin.

There might be a setting related to video buffering to change, or something, I do not know. But this is beginning to be infuriating.

Is this a Google' crackdown on browsers not beging Chrome? Or am I an isolated case?

Thanks in advance !

Working on setting up a new PC build. I've had to use some PC support website chats and many of them have just not acted right? For example, one would allow me to start a chat but then sent me directly to closing the chat like we were finished. The others would lock up my Firefox many times. Anything come to mind as to why this is happening? Windows 11 Pro v24H2 and latest Firefox version.

I cannot access this website: https://cz-usa.com . I get this message every time. Please help, this is very frustrating!~

Forbidden

You don't have permission to access this resource.

Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request.

From one day to the next I have the problem that I can no longer log in to the Google site. When I press the "log in" button, the page loads for half a second and nothing happens (screenshot 1). When I then want to access YouTube, the following page appears (screenshot 2). Everything works with other browsers. When I press "Gmail" on the Google homepage, I'm suddenly logged in and in my inbox. But I can't go to YouTube from there either, and I get back to the "screenshot 2" screen. I then have to log out of my account in gmail and log in again to access YouTube. If I then close Firefox, everything starts again from the beginning.
