First I thought this was a problem with Firefox 4 beta but now I am having the same issue with 3.6.16

About 70% of the times, Firefox does not open the web page and comes back with "Server not found" message. Interesting thing is it comes back with this message on the first 2 tries and then on the third try for the same link it will display the page. Always, 2 fails and 3rd time it works. Now during the first two times, internet commnection is working and if I try the same URL on IE it works without any issues. This started happening after I tried Firefox 4 beta. 4 is not uninstalled and I am back to 3.6.16. But the issue remains.

I am using Win 7 64 Home Premium, SP1 is not applied yet but all updates are in place.

Well, I'm using Firefox 4.0 and have the same problem. I tried to open my private homepage and my *.net-domain comes back with the "Server not found" message (my *.com-domain loads without any problem - same contents on both websites) I also tried to open my net-domain in FF portable - without any problems. Clearing the cache, deleting the cookies etc in FF4 does not help either. I also had the experience that FF4 does not load CSS5 websites (e.g. deviantart) properly (CSS does not work, website shows simply the html-version, a disgusting look). With FF portable the problem does not exist.

I tried this on different machines (e.g. Windows XP Pro SP3 (office PC), Win7 Pro 64, Win Vista SP2... (home PCs) and there I'm experiencing the same issues with FF4 and various websites.
