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!

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 access Bluesky (bsky.app) for business on my PC. Since the last update, I've been unable to access Bluesky from my regular Firefox browser. I can using other browsers, the mobile app, and, oddly, in Firefox private browsing. I've cleared my browser history, cookies, etc. I restarted the computer. I logged out of Bluesky (and now can't log back on the regular PC account because it claims I'm not connected to the internet). Yet, I had no trouble logging in using private browsing.

I've looked through settings, etc. and can't figure out what could be limiting my ability to access this website.

Whenever I now try open firefox, i get a verification page with old looking captcha visuals that is required to open firefox. Why and how do I remove that.

Madam or Sir,

I do not know what happens but since a few days I cannot access any more https://mathworld.wolfram.com/ which is crucial for my work.

Since I am blind, could you please help me.

I thank you in advance

Best regards
