I turn that off and still no Twitter and your system turns it back on again all by itself, your settings are doing what they want to do, not what I SAY to do. Now, I cannot get into Twitter.

Noch einmal: Ich habe keinen Zugriff mehr auf die Seite "Bestsecret.de" (You are blocked) und möchte das aber unbedingt! Was kann ich tun?

I use a site nextdoor.com and get email notifications. On opening the email, I see the option to view the comment, on clicking on view, this is what happens: . "The site ahead may contain harmful programs

Firefox blocked this page because it might try to trick you into installing programs that harm your browsing experience (for example, by changing your homepage or showing extra ads on sites you visit).

Advisory provided by Google Safe Browsing." And I can go not further. Why is this happening? How do I dump it and proceed with using nextdoor as normal. gargle is a blight on all users, and I want nothing to do with them. Is it time for me to change browsers?

Every time I try to use Google as a search engine in Firefox, this message appears. "About this page 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?:

I believe this occurred earlier in the year but was marked as solved. Immediately after Firefox automatically update to 151.0 64 bit today (in Western Australia), I am plagued with it as well.

I have tried disabling extensions and am not (I believe) running in incognito mode.

Any suggestions please?

I followed the instructions to turn off the Enhanced Security for that site. I have always been able to click on a single item like a blouse and it takes me right to it for purchase. But when I click on their menu like active wear I get the message below. Why can I access it on a single item be denied the rest of the site.

Access Denied You don't have permission to access "http://www.hsn.com/shop/fashion/fa" on this server.

I have a 100% repro rate of Firefox redirecting linkedin.com to linkedin.cn. Unfortunately there's another problem beyond the unwanted redirection: linkedin.cn no longer exits, it has been dead for years, I literally cannot reach LinkedIn at all. It was working fine a week or two ago. How do I prevent Firefox from redirecting behind my back? I see the status message (is that what it's called) in the lower left corner "Performing TLS handshake to www.linkedin.cn" and of course it only times out. I just verified with "Web" (different browser), it connects just fine, which suggests that it's a Firefox issue, not a system wide one.

I keep getting this message:

Firefox Can’t Open This Page

To protect your security, login.microsoftonline.com will not allow Firefox to display the page if another site has embedded it. To see this page, you need to open it in a new window. What can you do about it?

I can't open the link in a new window as I have to click on a tab and when I right click on the tab it only gives the pop up box that says "take a screen shot" etc.

I tried "allowing" the website for pop-ups but it still didn't work. I don't know what to do now.

Hi everyone,

I'm having trouble accessing my local network devices (a 3D printer and Raspberry Pi) using short hostnames like "http://impressora3d" or "http://impressora3d/". Firefox keeps blocking the connection with the "Looks like there’s a problem with this site" error page.

I've captured a network log using 'about:networking' and I can see that: 1. DNS resolution works perfectly and points to my local IP:

  "CompleteLookup: impressora3d has 192.168.1.10"

2. Firefox is upgrading the request to HTTPS (port 443) automatically:

  "nsSocketTransport::ResolveHost [...] impressora3d:443" -> "pushing io layer [0:ssl]"

3. The device rejects it because it only listens on HTTP (port 80):

  "Bad Socket 804b000d" (NS_ERROR_CONNECTION_REFUSED)

What I have already tried: - Disabled "HTTPS-Only Mode" entirely in settings. - Checked "Secure DNS" (DoH) settings (set to Increased Protection and added exceptions). - Cleared history and used "Forget about this site" on the hostname. - Typed "http://" explicitly.

Firefox still refuses to connect via plain HTTP (port 80). Is there any hidden 'about:config' preference or HSTS cache forcing this behavior for local unformatted domains?

Thank you!

Firefox recently updated on my Windows 11 desktop. As of yesterday (4/24/2026) and possibly earlier after typing www.facebook.com in the URL input space and hitting enter, no results at all.

After moving home from college Firefox no longer works. I can open the browser, and it doesn’t crash, but websites will not load and I can’t search anything. The weather data says it is not available. I have tried everything. Uninstall and reinstall, reset, scanned for malware, reset DNS on my computer, cleared cache both on Firefox and on my pc. If I open up Chrome websites work fine. When I reset Firefox through the uninstall window, it works but if I close that and reopen it it is broken again. I am beyond frustrated and any guidance would be much appreciated.
