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. I know this has been an ongoing issue, but it only happens with firefox on both my computers, vpn and all extensions off. Even tried a new IP address, same issue.

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

Ever since the last update, I can no longer watch recordings on xfinity stream with Firefox. What happened? Can I fix it? I sometimes have to start watching programs late, but they wont play while recording. I can watch those same recordings when they are finished, but not while they are still recording. I can watch those same recordings while recording on Chrome and Safari so it's not an xfinity problem. But for some reason not on Firefox anymore Is there a setting I need to change? Thanks Ron

Hello,

I'm seeking support to try to resolve an issue that has recently started happening. I can't be the only one who is experiencing this, so if this is resolved others can benefit too. I'm not a complete novice, but neither do I claim to be an I.T. expert.

I use my ISP's webmail service to access my emails. I'm aware I could use an email client, but I prefer to access via a web browser and have done so for many years. About a week ago, I was no longer able to sign in to my webmail. I thought it may be a problem with my provider, so I checked using other web browsers - Safari on iOS which worked and Microsoft Edge (using the same internet connection, same desktop PC) which also worked and continues to work without issue. I can only think it must be something wrong with Firefox? I can access the sign in page as normal using Firefox and select my email address, but after attempting to login I always get the same error message:

Sorry, we can't sign you in just now

Don't worry, it's just a quick pause to help keep your account safe.

Instead:

   Use a device you've signed in on before
   Try again from a familiar connection
   If you're on a VPN, switch it off and have another go 

Still stuck? If this keeps happening, get in touch with us (quoting reference IDF-12B) and we'll help sort it.

I have 2 extensions installed in Firefox - Adblock Plus and Ghostery. I have already added the specific URLs to the allowed websites list (first is the sign in page, second is what it redirects to):

mail2.virginmedia.com oauth.virginmediao2.co.uk

I have searched around for possible solutions, to no avail. Virgin Media advise only signing in on their main home page, but I've never done this as its just another step and extra unnecessary clicks. I don’t want to constantly be bombarded with news, offers and promotions every time I want to check my email, so I only use the direct webmail sign in.

I have tried clearing cache, cookies, etc. Then I tried to refresh Firefox, none of which worked. I also tried uninstalling Firefox, then using CCleaner to perform a clean up and registry scan to fix any possible issues, followed by a clean installation. To my surprise, I was able to sign in to webmail OK. However, the next morning, I got the same error. The only other settings I have tried tweaking is adding exceptions to turn off "Enhanced Tracking Protection" and "Block pop-ups and third-part redirects" on those 2 web addresses.

Any suggestions or options to try would be appreciated.

Issue persists on Incognito Mode and it goes away if I use different browser.

Since 2 days issue like this happened and it is retroactive meaning all previous conversations are also blank, all replies of chatgpt are blank except replies with image generation, those are fine.

Before you recommend me to do something please keep in mind that Incognito itself does not help.

I am able to share that chat, paste it in my firefox and page is blank. https://chatgpt.com/s/t_69f4b354cc188191a7959c2d443fed9d

I can use this adress on different browser and it works fine

When I try to attach file via drag & drop, the Firefox always display "Download file" as attachment. I don't know why because it properly worked before. but after some updates, drag & drop is not working.

The version of Jira at my office is not changed for years(v8.12.1#812002-sha1:7c28d59) and drag & drop is working via Chrome, Edge and etc.

Since the latest firefox update, I cannot complete log in to yahoo mail account. I've been a Firefox user for over 14 years. It asks for authenication preference, then will not complete it. This is only since latest update form firefox. I'm on an older Macbook pro but everything else works.

My laptop seems to be on the correct time zone, but when I access websites through Firefox they seem to see a different time. For example, it's currently around 6 p.m. where I live and that's what my laptop says, but when I open my email in Firefox it thinks it's already after midnight. This discrepancy has shown up with multiple websites, so I'm pretty sure it's something going on with the browser. It only happens on my laptop though, not on the mobile version of Firefox. There is no setting to change time zone in Firefox settings so I can't fix this. Please help!

when i go to my website on firefox it says "Secure Connection Failed" but it loads fine on safari. i've never seen it do this before. Is this a firefox issue?

full error message: Secure Connection Failed

The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. What can you do about it?

The issue is most likely with the website, and there is nothing you can do to resolve it. You can notify the website’s administrator about the problem.

Error Code: PR_CONNECT_RESET_ERROR

how do i fix this?

Hi!

We have a intranet site that works in Edge and Chrome without issues with the site added to "internet options". But for some reason we are getting 401 Unauthorized when trying to access it from Firefox. I have tried adding the urls to: network.automatic-ntlm-auth.trusted-uris network.automatic-ntlm-auth.allow-proxies: true network.automatic-ntlm-auth.allow-non-fqdn: true network.auth.force-generic-ntlm: false network.auth.force-generic-ntlm-v1: false

Ingocnito mode , same error. I have tried disabling all plugins. Disabled DNS over HTTPS.

HTTP/1.1 401 Unauthorized Server: Microsoft-IIS/10.0 WWW-Authenticate: Negotiate X-Powered-By: ASP.NET Date: Mon, 25 May 2026 08:15:41 GMT Content-Length: 0

When I login to a site where there are many widgets (windows) on the screen - the windows are all missing scroll bars. If I login under a different browser they are there. This happened about a week or so ago. It has to be a setting change in Firefox. Please advise.

First off I have always used Firefox as my default browser... better than all the rest. For the last week I've been working on a project on ChatGPT and have multiple times dragged and dropped a screenshot directly into the chat until today... now it gives me a red warning label at the top that says that this browser does not support import of jpeg, png, heic... but I've been doing it all week. Has there a change? How do I keep doing this? And now it won't even allow me to add an image here.

My files are stored on external hard drives within Dropbox. The hard drives are mapped to my computer. I can no longer attach files from these drives to anything through Firefox. I can still attach through Chrome, Bing, Safari etc. Any suggestions how to solve this problem. I am NOT attaching through the Dropbox website. I am attaching through the full path showing drive etc. Thank you.

Hello all

 Firstly I have been using Firefox for about 2 decades and it has always worked perfectly - you can take a bow.
Now for my problem
I have been using Firefox for internet banking for many years without any problems - the usual login, password ans secret questions. Just after Xmas my bank updated it's website and suddenly nothing works. I was told that it now only works on Chrome and NOTHING else - not Firefox, Edge or anything else. I am able to log-in but can't see my account balances or perform any other functions - it just jams up to the point that I even have trouble closing Firefox.
I use Firefox exclusively because I don't trust Chrome or Google - they are just a massive data collection/sharing operation. I have Chrome Mask installed but it just doesn't make any difference.

 Is there anything that I can do or add-on to over-ride this problem?

I am running Mint Linux 22.2 with Firefox 151.0.1

Content Security policy blocks essential scripts no matter what I do.

It's new Firefox installation, Troubleshoot mode, Enhanced tracking disabled, I'm not on VPN, can log into X.com in another browser just fine.

It's the reason #1 I don't use Firefox. I thought the issue would be fixed but it has been like this for long time.

Yet whatever I do, whatever I turn off this pops up:

Content-Security-Policy: The page’s settings blocked the loading of a resource (default-src) at https://abs.twimg.com/responsive-web/client-web/bundle.Conversation.721fc4aa.js because it violates the following directive: “default-src 'self'”

The screenshot is from Zen, but it uses Firefox and the issue is the same in Firefox.

With Mozilla Firefox for Linux Mint 150.0 after logging into Chase Bank , when trying to pay off my credit card, I get a message: "It looks like this part of our site is not working right now". However the site works perfectly with Chrome, thus the problem must be with Firefox. I have cleared the Chase cookies and still getting the same result.

With every release of Firefox I find that more and more websites that I use become unusable with Firefox, meaning I have to constantly switch between browsers that are not broken, like Chrome and edge. Before abandoning Firefox altogether I would like to know if it is possible to repair Firefox. The latest site Firefox that causes Firefox to crash is thai-language.com, which returns the completely false and meaningless message "The proxy server is refusing connections Firefox can’t connect to the server at www.thai-language.com". This worked well until the latest 'upgrade' or rather 'downgrade' from Firefox.

Fonts in the digital issues of the LA Times are changed. They appear as serif initially, but quickly change to a sans serif which appears to big for the space. The headlines are squeezed together and touching. Body copy is affected also. How to keep the fonts as they first come in?

I am having the problem a fix was created for previously where attempts to sign in to my google account continually redirect to a request to clear cache and cookies. Have done so multiple times, still can't log in. Can log in on Chrome so definitely a Firefox-specific issue.

We have resolved an issue with Google prompting users to ‘clear cookies and site data’ when logging in. A fix has been published, via Firefox remote settings that does not require a Firefox upgrade. Users will receive the update over the next 6hrs, if you would like to update immediately simply restart Firefox.

Note: The issue was related to CHIPS being enabled in Fx131, this feature has been temporarily disabled while we resolve the issues. Users who have disabled 'Allow Firefox to install and run studies' in Privacy & Security settings will need to enable to receive the update.
