It is only this one website and I was able to access it about a month ago but not now. I recently installed some software from C-net that included some browser add-ons. I later attempted to delete everything but noticed when I started Internet Explorer about 2 weeks later it went to the home page of one of the products I had uninstalled. I've reset Firefox but that didn't help. My android device is able to access the website. So it must be something on this computer but why only this one website?

Thank you so much for your help. Your suggestions did not solve the problem but got me thinking. Initially, Firefox help suggested deleting all the cookies and history which I didn't want to do. When your suggestion didn't work, I began to think maybe History/Cookies might be the problem but I still didn't want to delete them all. I went back to the Firefox help site and asked how I could just delete one site from History/Cookies. I followed the instructions to open History and select show all. Then I typed in the URL for So. Cal. Edison. From the list that came up, I tried to open the sites one by one. Several would not connect but one gave me a different message, a message directly from the site saying the section I was looking for no longer existed. However, there was an Edison logo on the page and when I clicked on it, the site opened. No more problem! While this solution makes an intangible sense, I don't truly understand the mechanics behind it. Thank you. I appreciate your help. Without it I might never have resolved this.

Typically, if a website is blocked in multiple browsers, then external software or settings are involved. This could be any of the following:

  • filtering software blocking the site for some reason
  • malware blocking the site
  • site redirected in the Windows hosts file
  • DNS servers not functioning correctly or replaced with bad DNS servers

I know I'm not explaining these thoroughly; it's late here. :-(


I'm not sure whether this is related, but you may want to disable or remove the General Crawler extension. You can disable here:

orange Firefox button (or Tools menu) > Add-ons > Extensions category

If there is no remove button, other threads have indicated that you can find it in an obscure location and delete it there.

First, open Help > Troubleshooting Information. In the Extensions table, next to General Crawler, you should see a GUID (a long string of letters and numbers between {curly brackets}).

You will look for that GUID in the following folder.

In the start menu search box or in a Windows Explorer navigation bar, enter:

%APPDATA%\Mozilla\Extensions

and press Enter. Do you see the GUID for General Crawler as a folder name here? If so, select and delete that folder to remove the extension.
