Firefox コミュニティフォーラム

I am experiencing an issue where YouTube videos are very slow, buffering frequently, or playing in low quality when using Firefox on my computer. This problem happens even when my internet connection seems fine for other websites.

I have tried refreshing the page and restarting the browser, but the issue still continues. I would like help to understand what might be causing this and how I can fix it.

Please let me know if you need more details or steps for me to test.

I have access issues on 2 web sites: >Amazon Prime video gives message "

 "You are running an unsupported version of this browser.

Please update to the latest version. View all supported browsers and OS versions on Prime Video. If still running into issues, reach out to customer support with the error code: 7132" >Etsy gives message "Access is temporarily restricted" I do not have issues with either of these when I access via Chrome. Hopefully you can help, I've tried to troubleshoot this for a couple of months. Thanks, Karen Florup

When I try to make a Google search I get the following message, "I'm not a robot" with a reCAPTCHA: "Our systems have detected unusual traffic from your computer network. This page checks to see if it's really you sending the requests, and not a robot. Why did this happen?". This happens on Firefox, but not Chrome or Edge. I have scanned with Malwarebytes, Bitdefender, Hitman Pro, Trend Micro House Call and Microsoft Defender, nothing detected. Running Win 10 (64) with 'Extended Security Updates', Firefox 152.0.3 (64), no additional Extensions or Plugins, no VPN and have run through the troubleshooting suggestions. Also I uninstalled and reinstalled Firefox. Note: currently I do have extensions installed, previously I did not, however with or without the problem exists Attached screenshots

I'm having problems Logging Out of my Credit Union website: https://www.myconsumers.org/ I tried clearing cache and cookies but that didn't work. Log Out is working OK with Google Chrome. I may have to make that my default browser once again.

Hello, for some time now I've been experiencing a number of problems with the latest Firefox updates.

Today I have version 152.0 (64-bit), which was updated again this morning. I restarted my mid-2015 MacBook Pro Retina. I have fiber optic internet, which is very high speed.

I've been using Firefox for over two years.

1) For the past eight days, I've been experiencing many problems with Google Meet; I get freezes, audio and video dropouts...

2) For the past three days, I haven't been able to log in to this website: https://creators.spotify.com/pod/login

3) For about ten days, I've been having trouble logging into my Stripe dashboard, with significant slowness and/or crashes.

4) In Notion, I'm also experiencing significant slowness, with pages taking a long time to load.

In short, several problems that I didn't have at all a month ago or before.

But now it's a nightmare.

I don't have any of these problems in Safari or Google Chrome.

So what's going on in Firefox?

Why is it such a hassle?

Thanks for your feedback.

I have recently switched to Firefox, from chrome/edge and I love it. One thing that I cannot get over, however is video conference quality. I call my parents every week and we use Google Meet. The video quality on my end is not only limited to 720P on Firefox, but it is cropped and grainy. It is really bad. I cannot use it. I've tried everything I can think of, but I can't fix it. I don't know if there is a way to submit direct feedback to Firefox, since the link to their feedback site leads here, but I wish they would improve this.

Hi there. The past few weeks whenever I try to view any YouTube embed on any website I just get this error and the video does not play: Sign in to confirm that you're not a bot

Of course I am signed in but it does nothing. It works in other web browsers, just not Firefox. I've tried resetting my cache and cookies, private windows, and disabling all extensions but nothing seems to work.

I'm running Firefox on Win10 with no options to upgrade to 11. Since the latest firefox update installed, I'm getting a screen that says "Oops, something's wrong," and then I'm kicked out of gmail. A screen asks about sending a report to Firefox, which I check OK for. Today this is happening about every minute to 30 seconds . What needs to happen?

Hello!

When opening a native <select> dropdown in Firefox, the hover/highlight bar on an <option> does not span the full width of the dropdown popup — it only covers roughly the left portion (about half) of the option row. The rest of the row to the right stays un-highlighted, which looks broken. Chrome (and Chromium-based browsers) render the same markup with a full-width hover highlight.

Steps to reproduce:

Open the attached test page (or any page with a full-width native <select>) in Firefox on Windows. Click the select to open the dropdown. Move the mouse over the options. Expected result: The hover highlight covers the entire width of the option row (full width of the dropdown popup), as it does in Chrome.

Actual result: The hover highlight covers only part of the row width (about half), leaving the right side of the option un-highlighted. See attached screenshots: (attach Firefox screenshot here — and optionally a Chrome screenshot showing correct full-width hover for comparison).

Notes / what I already ruled out:

It is not CSS-specific to my site. I reproduced it with: a styled <select> (custom background/color on <option>, dark color-scheme), a select with the option background removed entirely, the box-shadow: 0 0 10px 100px <color> inset "full-width" workaround, and a completely bare <select> with no custom CSS at all (appearance: auto). All of them show the same half-width hover in Firefox. Chrome renders all of the above with a correct full-width hover. This makes it look like a Firefox-level rendering behavior of the native dropdown popup rather than something controllable from page CSS. Environment:

Firefox version: Latest OS: Windows 11 Display scaling / zoom: (fill in — e.g. 100% page zoom, 100% Windows display scale; mention if non-100%, since DPI scaling can be relevant)

I followed the instructions for turning off Enhance Security on the website QVC an I still get the same error. I'm reporting it again.

There's a particular couple of links in Gmail, from a specific email, which sends links I need to go to, and they will not open, yet gives an error message. This has been happening for years. The sender sends these links to all members, and I'm the only one who cannot open them. 2 decades ago I was able to open them.

This is in response to an email sent to me today June 27, 2026, with authorization code (111081). I just purchased a new PC desktop in May of this year. The problem I'm having with Firefox web browser is every time I use your browser the statement comes across the top of the page that windows browsers are no longer supporting (windows 10). My computer is a (windows 11), and there are other websites that I go to that are blocking me from using their site because it. Additionally, I am trying to setup a new email system via Proton email, which use VPN's that actually appear that someone else signing in from another location in order to keep their users safer. Also, I'm dealing with Comcast email system which they are in the process of deleting their (@comcast.net) accounts. I spoke the company that I purchased my computer from and they told me that I would need to get in touch with Firefox to get the windows 10 information off your website. I have copied the info for my computer below. I deleted my serial number because I didn't think you needed that. I actually spoke about having windows 11 in my last response to you all. See what your data provided below. Thank you kindly for any help you can provide. V.

This page checks to see if it's really you sending the requests, and not a robot. Why did this happen?". This happens on Firefox, but not Chrome or Edge. If I 'Allow' Google in the 'Exceptions - Cookies and Site Data' then I do not get the message, but it takes several seconds for Google display the resulting page. However, if I delete the cookies/cache the message will return and I have to redo the reCAPTCHA.

Running Win 10 (64) with 'Extended Security Updates', Firefox 147.0 (64), no additional Extensions or Plugins. Also I uninstalled and reinstalled Firefox.

I recently bought a new computer with Windows 11. All my passwords and user names have been transferred to this new computer and appear to work. However, with Win11 on this new computer, I am not able to log into my Costco account w Firefox and have to use Chrome or MS instead.

Please advise, Thank you, Kathy Economy
