My Firefox installation has gone deaf & dumb after I upgraded from 3.0.1 to 3.0.2 a few days back. Uninstalling, registry editing (since the Firefox uninstaller is 'weak') and reinstalling either 3.0.1 or 3.0.0 (that both used to work) has not worked either. It times-out trying to log-on the any website. IE7, Opera 9 and Chrome working OK on same machine; just Firefox has issues.

Used the Mozilla forums and there's quite a bit about this from this and earlier version updates but none of the threads ever come up with a definitive fix and I guess a lot of users just uninstall it and use something else. Threads include the actions of firewalls, spycatchers and anti-virus but I have eliminated them.

I am running Vista Business.

Have you try to delete all TEMP files and Cookies?

Maybe you use Win Bubble for to take the Ownership of all Directories and Files in Users DIR of Vista and delete all Mozilla and Firefox entrees there.

Win Bubble you can download from TV Download.

Hope that helps. Have luck

Cheers.

Most common reason for not connecting after upgrades is that the security levels of your sustem have been changed. Check that they have not been moved to maximum on your anti virus which will stop internet connection most times. Easy check just turn of AV and then try to connect. If this does not work check the security settings in XP

I guess you tried already ensuring your firewall has given permission to the new version of Firefox to connect with the internet.

03 is already out to replace version 02

I WAS a Firefox user. Normally after an update it works flawlessly for several weeks then starts to develop glitches. I always kept Opera on my computer but it also had issues I couldn't live with and was never my default browser. I downloaded the 9.6 beta version and so far it is absolutely perfect. I don't know what they did to it but whatever they did made it perfect. I have now for the first time made Opera my default browser. Will it last ?????? Who know?

Hi

That Firefox issue is no unknown to me - happened several times, always after some updates. Firefox, for some reason, switches to "use proxy" and because no proxy is entered, it appears that there is no connectivity.

Do the following:

Go to "Tools" -> "Options" -> "Network".

In the first field "configure how Firefox connects to the internet" click "settings".

In there, select "no proxy".

Click "OK" and "OK" again, then restart Firefox. All should be fine now.

Best regards.....

Thanks for the feedback and suggestions.

Reimar: What's Win Bubble. Are you suggesting there's some uninstallable widgets of Firefox in the the User black hole that regular uninstallers and registry cleaners miss?

benjamat: I did all the firewall disabling with no result. I even canned the whole Norton Internet Security using their downloadable Norton killer (speaks volumes that their bundled uninstaller) but Firefox still dead. It's on Vista btw.

katana: That was tried when I had NIS installed. Changed from 'Custom' to 'Allow' no succes. Deleted and let NSU find the new install no success. Repeated with 4 different versions of Firefox including the last 2 that worked on the machine, no success.

Wash: versions 2.0.0.17 through 3.0.3 all DOA.

Gary: The newest Opera does look better but still has some display peculiarities on some secure sites. Handy backup. I am really warming to Chrome as I am through a marine vSat system and it's the fastest I have ever seen any browser, even Firefox.

Thanh: But I AM using a proxy server (part of my clients internet firewall) and Firefox and the other 3 browsers all connected happily once the proxy setting were used. It's only Firefox that is behaving like theres nothing out there after the upgrade. The Firefox default is 'no proxy' so yes it doesn't connect since I am on a proxy. However, after configuring the proxy, STILL no connect.

I have posted the complete story on the appropriate mozilla forum and after a day, no answers as I clearly have removed all suggestion that it's third-party firewalling and killed the usual answer that Firefox is not the problem. Their forum indicates that there's a lot of this about and not a single resolved case (apart from the ones that WERE firewall related).

Try rebooting your router

I had the problem that some major web pages would not display and a simple rebooting of my Linksys router solved the problem.

^ I have my own wireless router and that's been power cycled. no joy. The clients server is in Norway was reset a couple of times and still only Firefox is deaf and dumb.
