Firefox doesn't block any websites. It sounds like you have a deeper issue, possibly caused by a Firefox extension, or something interfering with the networking components used by your computer.

Are you able to access the same sites in another browser on your computer?

Can you describe what happens when you attempt to visit a site which doesn't load in Firefox?

I do not know the answers to your questions. This just started happening today. I tried to go to a website, and it simply wouldn't load. A little gray circle was in front of the website's name on the URL box. I clicked on it and got this small window with three boxes at the top--can't remember what the first one said, but the second said: Permissions and the third said Security. I clicked on those and one of them sent me to this mozilla site with a bunch of gobbledy gook about grey globes and triangles and how I was being "protected"==Oh yeah, the "Security" box, when I clicked on it, told me the website I was attempting to view wasn't encrypted or something. So, I know it's not my "network" or any of that crap. It's definitely something to do with Mozilla--I just wanna know how to turn it off, or at least bypass the "Security" thing. It's MY business what websites I go to, not Mozilla's.

Okay, the globe appears for all sites that use HTTP addresses. Those do not use a secure connection and there is nothing abnormal about that. That icon is just for your information in case you were expecting a secure site (padlock icon).

Question for you:

When the site loads (or fails to load), does the page have an error message, such as "The connection was reset", or "Server not found", or is it just blank? More information would be helpful here. Tell us what you see.

When you have a problem with one particular site, a good "first thing to try" is clearing your Firefox cache and deleting your saved cookies for the site.

(1) Clear Firefox's Cache

"3-bar" menu button (or Tools menu) > Options > Advanced

On the Network mini-tab > Cached Web Content : "Clear Now"

If you have a large hard drive, this might take a few minutes.

(2) Remove the site's cookies (save any pending work first). While viewing a page on the site, try either:

• right-click and choose View Page Info > Security > "View Cookies"
• (menu bar) Tools > Page Info > Security > "View Cookies"

In the dialog that opens, you can remove the site's cookies individually.

Then try reloading the page. Does that help?

If Firefox won't load any sites, that could be an interaction between the recent security update(s) and your security software. Did you check out this article?

• Fix problems connecting to websites after updating Firefox

forget it--I can't get a straight answer. I know I am not so special that I am the only user this has happened to. I went thru all of the "fix this" info screens I could find and then I hit this piece of candy: Open Action Center by clicking the Start button Picture of the Start button, clicking Control Panel, and then, under System and Security, clicking Review your computer's status.

Tried to do that stuff and guess what? AS USUAL the names given to things to click on DON'T FREAKING EXIST! I don't HAVE an icon for "System and Security" I have a "System" icon, but under that one there was no "Review your computer's status" So--screw it. I am not a computer geek. When the instructions don't match reality, I cannot follow them. I'll just find another browser. Knew Firefox being good wouldn't last, thanks to "improvements".

There are multiple ways to view the Control Panel in Windows 7. Based on what you've quoted, the instructions assumed you were viewing "By category" as shown in the attached screen shot. I think this is the default. You might have changed it to icons at some point to be more similar to Windows XP. I don't know whether there is a corresponding icon. If you decide you still want to use Firefox, try switching your control panel to view by category to carry out the steps in the article.
