I have always updated automatically,. When version 7 loaded the other day, I thought nothing of it. It has been extremely slow and buggy since it loaded and I want to return to version 6 right away. This has happened on every connection from hotel WiFi to my Verizon FiOS at my home office. Help

The default of the pref network.http.max-connections has been increased from 30 to 256 in Firefox 6+ versions.

You can try to decrease the value of the pref network.http.max-connections from 255 to a more modest setting like 30 as used in Firefox 3 versions.

The two or three problems may not be directly related. Firefox 6 is no longer supported or considered secure, it is not recommended that you downgrade to that.

  1. see firefox crashes <-- clickable link --
    if you are seeing crashes lets try to find the cause, please read that article and attempt to provide the crash ID.
    • please also try to explain what you see and when these crashes occur
  2. Speed is terrible, what is happening freezing, slowly loading, slow downloading or something else ?
  • if you do need to downgrade currently it would be recommended you use firefox 3.6.23, that is secure and supported, but you will loose some features and advantages & fixes of the newer versions

Excellent. That made a big difference. I wish I knew why, but it worked, and that is all that matters! Thanks!!

Thanks. I used another solution, dropping the http connections from 256 back to 30 and that seems to have done the trick. No problem at home on FiOS, but big problem at hot spots and hotels with slower connections.

Glad you fixed the problem.

Developers seem to be struggling to figure out why, in some cases, the dropping of the connections limit helps. It is suspected there must be other underling factors. Hopefully some of those with the problem will try to help.
