Mozilla Firefox unable to connect to certain sites
 

So far I have encountered this on http://www.vgcats.com/ and http://uk.youtube.com/

The error message I get is this:

"Server not found

Firefox can't find the server at uk.youtube.com.

Check the address for typing errors such as
ww.example.com instead of
www.example.com

If you are unable to load any pages, check your computer's network
connection.

If your computer or network is protected by a firewall or proxy, make sure
that Firefox is permitted to access the Web."

I'm sure any FF user has gotten this error before.

All other sites I have tried seem to work fine. But other browsers (Opera, IE7) get the same errors. I use AOL (not out of choice) and I am always connected to the internet via a Netgear wireless router (wired to the PC). When I use the AOL browser, all sites, including Youtube and VGCats, display fine.

Help? :P

I got the same problem too. I'm also using AOL...but I wonder if that is the case.
Some of my bookmarks links doesn't work anymore and that both on Firefox and IE and also both on my laptop and pc.

Even the advertisement on this page failed to load!

Well for me......the solution mentioned above doe'nt work!

I'm having the same problem. unable to access Youtube, newsnow.co.uk, even my ftp and mysql for my website. I'm also on aol broadband, using a netgear router. I use Firefox on my laptop, and have been unable to access these sites for 2 days now. Have tried all sorts. Was thinking it was the MTU settings in the router, but now i have stumbled across this thread, it seems that people are having the same problem. I have now checked on the PC which has AOL software installed, and can access youtube on that, so it looks like an aol problem. I sent them an email yesterday, but have heard nothing back from them. I'm seriously considering quiting AOL after 10 years with them now.

If anybody finds a solution, please let me know. I'm supposed to have a website assignment handed in next Friday, and this is causing me no end of problems.

Hmm, weird. This has been happening over the past two days or so for me as well. I wonder if it's related. Maybe AOL are trying for FORCE us to use their crappy, overloaded browser?

Or maybe I'm paranoid.

Still looking for a solution that works!

i think you might be on the right track

Re: Mozilla Firefox unable to connect to certain sites
 

Try accessing the sites without using bookmarks.

If this works, it means that there was something in a bookmark that is no longer valid (usually due to a site upgrade).

Re: Mozilla Firefox unable to connect to certain sites
 

The bookmarks links wasn't the culprit.....I checked it using search to access the site and it still the same problem. At least you guys can access it via AOL browser, I haven't signed up for it and now it wouldn't let me create a new user.

This started happening to me two days ago on the Friday, is it the same with you guys?

Have you tried clearing your cache files ?
Under Tools > Clear Private Data; or Ctrl + Shift + Delete
