I have been using Firefox for several years now. Up until this year, I never had problems. Then, sometime within the last year, I noticed that when I visited websites, I would keep getting the "server not found" message and I would have to press "try again" sometimes up to 5 times before I would get to a website. I also get email lag in Outlook Express 6, sometimes it will say something like server not found and I'll have to manually select receive and emails will come through.
I am running XP SP 3, Verizon Internet Security Suite, and Firefox (latest version) for browsing and OE 6 for email/ groups. I have tried all sorts of troubleshooting as suggested on various websites, but to no avail. I have uninstalled Firefox from "program permissions" in Verizon Security Suite and then reinstalled but no effect. I have also tried some advanced network troubleshooting techniques as suggested at Microsoft, but no help.
I am suspecting maybe Verizon Internet Security Suite is interferring somehow, but I don't know how to troubleshoot further other than what I have already done.
The problem makes it almost impossible to download files and many times I have to refresh several times before I get the opportunity to download a file.
So the bottom line is that Firefox and OE 6 work, but very sluggishly and reloading/ refreshing many times before finally getting email and or getting to websites. As I say, it's been going on for about a year.
Any suggestions would be greatly appreciated.
Thank you, Bill Penney
