Unusually slow downloads

My download speed with the current version of Firefox has been between 165 and 250 Kbs. I installed 4.0 Beta 3 and the download speeds remained the same. I am running Windows 7. I had Verizon check my DSL lines and they tested 1.2 Gbs download and 0.75 Gbs upload. I even had a tech come out to verify we had no line problems.

The downloads are so slow that I often can not get a YouTube video to run without stuttering.

I have ESET Anti-Virus and firewall.

It's possible that you are having a problem with some Firefox add-on that is hindering your Firefox's normal behavior. Have you tried disabling all add-ons (just to check), to see if Firefox goes back to normal?

Whenever you have a problem with Firefox, whatever it is, you should make sure it's not caused by one (or more than one) of your installed add-ons, be it an extension, a theme or a plugin. To do that easily and cleanly, run Firefox in safe mode (don't forget to select Disable all add-ons when you start safe mode). If the problem disappears, you know it's from an add-on. Disable them all in normal mode, and enable them one at a time until you find the source of the problem. See this article for information about troubleshooting extensions and themes and this one for plugins.

If you need support for one of your add-ons, you'll have to contact its author.

If the problem does not disappear when all add-ons are disabled, please tell me, so we can work from there. Please have no fear of following my instructions to the line, as all can be easily undone.
