Firefox Community Forum

So i have freshly installed firefox, every time i look up something on google i don't get any AI overviews, but when i use google in a private window google's ai overview works in there. what is going on? (keep in mind i have ublock origin activated on both windows but the ai only works in private mode where im not signed in)

Started a few days ago, I'm getting a Access Denied error on Sky News web site-:

Access Denied You don't have permission to access "http://news.sky.com/uk" on this server. Reference #18.6e3f655f.1775840716.11cf0872 https://errors.edgesuite.net/18.6e3f655f.1775840716.11cf0872

Has anyone a clue? I can go to the Sky Watch live..... when I click any link I get the same result above. This happens when running Firefox in safe-mode.

Running Win 7 x64 115.33.0ESR This is the only problem I have.

I am running Firefox version 153.0.1 on a 64bit install of Windows 11.

A few days ago I had to factory reset my computer, including a clean Windows install. Since then, when attempting to access https://vodafone.cz/muj/prihlaseni, I get an Imperva Error 15 "Access Denied" error screen - screenshot attached here. Clicking the Imperva logo on the bottom of the error message leads to https://www.imperva.com/why-am-i-seeing-this-page/?src=23.

I was able to access the site in the past, most recently on July 8, 2026 - this would have been Firefox version 152.0.5.

This error persists in troubleshooting mode but not in private/anonymous (with or without extensions enabled), nor does it appear in Microsoft Edge or Firefox on Adroid.

Clearing cookies and cache did not help - in fact the error first showed up on a clean install of Firefox, when there weren't any cookies or cache stored yet. I've tried different DNS over HTTPS settings and listing the site as an exception in settings, but none of this made a difference. Enabling Firefox's built in VPN also made no difference, regardless of the selected location.

I found a recent post (https://support.mozilla.org/en-US/questions/1588627) describing a similar issue on a different website and tried the suggestion listed there to try a fresh profile - this seemed to work, but within a couple of minutes of browsing the error message returned. I've even reinstalled Firefox entirely, but this too did not help for long.

Interestingly enough, the error message lists a proxy IP address (not blacked out on the screenshot) despite the fact that I am not using a proxy.

The website provider's tech support claims this is an issue on the user side, not theirs - they have not been able to replicate the issue.

Is there anything I'm missing that would explain why this is happening?

Thanks!

Only with Deepl, I click on this program and immediately I get a window which says "Checking if the connection is secure". Underneath this, I have to check a box which says "Verify if you are human", with the Cloudflare logo.

I've tried everything to get rid of this as it slows me up. I've tried Settings/Installed Apps, Search, Programs etc but it is not contained in any of these lists. I contacted Cloudflare who gave me some suggestions which didn't work (can't remember them), then said it was part of Mozilla and it was them that have attached this window so I need to contact you to get rid of it.

Can you help me please?

I am experiencing an issue where Google.com (other google domains work fine) will not load in Firefox, resulting in an infinite loading loop. Other browsers on the same system (Brave) work fine.

Here are the steps I have already tried:

Reinstalled Firefox completely

Removed Firefox via sudo apt remove --purge firefox -y

Cleared all user profiles and caches: ~/.mozilla/firefox, ~/.cache/mozilla, ~/.config/Mozilla

Reinstalled via Flatpak

Tested network connectivity outside Firefox

curl google.com works correctly

DNS resolution works via getent hosts google.com in the host system

Checked proxy settings

Ensured “No proxy” is selected in Firefox → did not resolve the issue

Tested in Safe Mode (disabling extensions)

Problem persists, so not caused by extensions

Tried disabling IPv6 inside Firefox

network.dns.disableIPv6 set to true → no effect

Cleared DNS cache inside Firefox

about:networking#dns → clicked “Clear DNS Cache” → no effect

Disabled DNS-over-HTTPS (Secure DNS)

about:preferences#privacy → “Use secure DNS” → disabled → no effect

Disabled HTTP/3 (QUIC)

network.http.http3.enabled set to false → no effect

Verified Flatpak network permissions

flatpak info --show-permissions org.mozilla.firefox shows network access allowed

Inside the Flatpak shell:

flatpak run --command=sh org.mozilla.firefox getent hosts google.com

→ returns only IPv6 address: 2800:3f0:4001:839::200e google.com

Firefox is my browser but unable to access email page, "Access denied. You don't have permission to access .... on this server". Internet operating ok otherwise. Also, I have an old Windows 7 laptop which works fine - emails available and open ok.

Suddenly I can no longer connect to gmail or googlemail on mozilla. It works fine everywhere else. At present I'm having to use Microsoft Edge for emails. Everything else on Mozilla seems to work fine. I don't get any messages to say why. The input just sits there with the fullstop going left and right. Any ideas ?

Amazon Facebook Ebay National Lottery and others just refuse to load.I tried troubleshooting mode,it worked once and now it doesn't.I believe I'm not the only one with this prob. Help? Thanks.

別のノートパソコンやスマフォではアクセスできるがデスクトップパソコンだけで　https://www.minim.jp/　アクセスできない。他の多くのサイトにはアクセスできる。

今まで利用していたChromeでもEdgeでも10日前にアクセスできなくなったので、試しにFirefoxをインストール、その後、このサイトにアクセスできた。それでhttps://www.minim.jp/に接続するときだけ、Firefoxを利用していた。

しかし、28日アクセスすると「エラーコード: PR_END_OF_FILE_ERROR」が出るようになりアクセスできなくなった。 現在もChromeやEdgeではアクセスできない。

Today (4/27/2026) I am suddenly unable to log in to My Account on various websites (eMail, grocery store...) The business page opens but when I try to go to the account login page, I either get a blank page or the page spins and spins and never goes to the login page. I am able to get to the logins on Safari. I've cleared cache and cookies, and closed out of Firefox and reopened.

I am getting this page when trying to enter some of my accounts; including bank accounts

Why is this step needed?

We detected unusual activity from your device or network. Reasons may include:

Rapid taps or clicks JavaScript disabled or not working Automated (bot) activity on your network (IP 9.244.4.94) Use of developer or inspection tools Need help?

or others that ask me to call some 800 number and give them info to my computer and IP address. 

Are these real or hacker related?

I am getting the following message on a couple of different website pages today. "Please unblock challenges.cloudflare.com to proceed." I don't know what this means! What do I do to unblock/fix this, please?

Thanks, Paul

Here is the site I desperately need to click around on. I can't access more than the homepage via Firefox (laptop), Safari (my laptop and iPhone) or Microsoft Edge (my husband's laptop). For the links on the page, I get an error message every time. And I have disarmed as many cautionary protections as possible. Yet other people seem to be able to use the site like a roller rink.

Ideas?

Thanks.
