I keep getting this message:

Firefox Can’t Open This Page

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!

Something is wrong with your network configuration We checked your network configuration and found that the following domains are not accessible.

You block me when I want to open deposifiles.com I trust that site and have used it for many years. Stop this blocking action please.

I have an ASUS laptop running Windows 10 - I can no longer access outlook.com in a regular browser, but I can in a private browser. I can access outlook on my ACER laptop running Windows 7 in a regular browser and I can on my desk top computer running on Windows 7 and using the GOOGLE browser. I only seem to have a problem with outlook in a regular browser using FIREFOX on the ASUS computer. Is there something in the FIREFOX browser settings that would prevent the connection?

You're blocking me from a website that I've visited before called The-wealthsociety.com. Why and who gave you permission to block me?

I have two desktop computers. both were fine. Now when I try to access a site i have gone to innumerable times it says "Blocked access". I can still get to the site on the other computer, but it is annoying to have to hop back & forth. I looked at the settings page, but I have no idea what I need to change to regain access.

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.

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