Use Dial-up, Firefox 21 and I need to disable Firefox from pinging after I start browser i.e. addons-star-net.zlb.phx.mozilla.net and verisign. I've no addons.


Hello, I use Linux operating system and ever since updating Firefox to version 21, when I start the browser, about two minutes pass while at a fully downloaded webpage, my dial-up modem starts blinking, which means someone is pinging. I launched netstat in terminal, and output shows the following: Active Internet connections (w/o servers) Proto Recv-Q Send-Q Local Address Foreign Address State tcp 0 0 bud02s04-in-f0.1e1:http ESTABLISHED tcp 0 0 sof01s02-in-f8.1e1:http TIME_WAIT tcp 0 0 bud02s04-in-f3.1e1:http TIME_WAIT tcp 0 0 OCSP.TKO2.VERISIGN:http TIME_WAIT tcp 0 0 bud02s04-in-f3.1e1:http TIME_WAIT tcp 0 0 sof01s02-in-f4.1e1:http ESTABLISHED

Another one I see in the output is https : //addons-star-net.zlb.phx.mozilla.net with other output.

It's annoying because it slows my connection down, and usally lasts about 5 minutes. So, I disconnect as at first I had no idea who was pinging my connection as I do not have anything running that would automatically ping a server.

I've disabled automatic update for search engines, do not have the Health Report ticked, and no spell checker ticked. I have all my extensions disabled, and removed the two addons (ghostery and self-destructing cookies) I did have just to see if this would stop the autopinging of Firefox 21. It didn't. Thanks for your time.

That's wonderful. Much obliged to you, philipp! The main ping was from all of my live bookmarks, a feature I often forget about in recent Firefox versions. So, I deleted all of my history and have my preference set where it now doesn't remember browser and download history, unless there's a way I can disable live bookmarks alltogether. Will do a search on it. Again, thank you! Regards P.S. Found what I was looking for. File>Preferences>Tabs> and unticked Don't Load Tabs Until Selected
