Firefox has become absurdly slow opening webpages. Can take a minute + to load. Please help.

more options

This started over a week ago. I try to link to a webpage (either from a link on another page, a bookmark or an email) and I can end up waiting for over a minute for the page to load. I have checked my PC's Internet speed (excellent), malware and viruses (none), firewall issues (none - in fact, the problem persists even with the firewall completely disabled), I've even upgraded my modem (no change). The problem affects Firefox and also Chrome and IE. It does *not*, however, affect my laptop or notebook. I'm at wits end at this point and any other ideas to fix this would be appreciated.

Some added toolbar and anti-virus add-ons are known to cause Firefox issues. Disable All of them.

I tried all of those at both links that relate to my issue, but none of them have made any difference.

It is possible that your security software (firewall, anti-virus) blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.

Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full, unrestricted, access to install for Firefox and the plugin-container process and the updater process.


Boot the computer in Windows Safe Mode with network support (press F8 on the boot screen) as a test.

Do a malware check with several malware scanning programs on the Windows computer. Please scan with all programs because each program detects different malware. All these programs have free versions.

Make sure that you update each program to get the latest version of their databases before doing a scan.

You can also do a check for a rootkit infection with TDSSKiller.

See, that's why I specifically mentioned that the problem was NOT being caused by my anti-virus program's firewall. That the problem persisted even after the firewall had been COMPLETELY DISABLED. So people wouldn't waste their time asking me if it was the firewall.

If it affects multiple browser then it must be caused by other software on your computer.

Try to reset (power on/off) the router. Try to disable IPv6. See:

Well, disabling IPv6 didn't completely solve the problem, but it helped a bit. I'm still getting lag, but it's now about half what it was. So, that's something. Still looking for a complete solution.

As I said in my first post, yes. PC is clean.
