Firefox doesn't work but Internet Explorer does...?

Question

I have had Firefox installed on my computer for at least a year now, but it suddenly doesn't work. It gives the "Firefox can't establish a connection to the server at www...." message. Strangely though, Internet Explorer works fine. I've tried all the help resources on the server and have done two virus scans. I also have cleared my cache, cookies, etc. But, it still doesn't work. Any Firefox experts out there?

Thanks

Answer 1

If you have Win XP or Vista

the best browser is IE8. I've found only one fixable problem with installation Adobe Flash Player plugin if you have too many add-ons. See: How to download any Add-ons to IE8 without the errors http://yefimsanswers.blogspot.com/2009/02/how-to-download-any-add-ons-to-ie8.html http://blogs.msdn.com/ie/archive/2008/03/20/add-on-management-improvements-in-internet-explorer-8.aspx

Did you set up a proxy in IE recently? Because if you use proxy in IE then you have to change it in Firefox as well.



In firefox, click 'Tools'/'Options'



Under the 'Advanced' tab, click 'Network', in 'Connections' hit 'Settings'



Then click on the radio button that says

'Auto-detect proxy settings for this network'. Hit Okay and try again

Answer 3

Have you tried different websites? There could be one site that just doesn't work. I've had a similar problem on Linux (Ubuntu) and I've decided it's related to my wireless USB stick.



Do you need to configure a proxy server or anything under network options?

Answer 4

Do you have Norton Antivirus or something else from Norton? Disable or uninstall it, restart the computer, then check to see if Firefox works again.

Answer 5

maybe your Anti Virus software block Firefox somehow?

Tried reinstalling?

Answer 6

There is a new version out there, have you downloaded it yet? It's Firefox 3.0.8. I'd uninstall your old one and start fresh.
