The very first time I loaded firefox on my laptop (which i bought only a couple months ago) the syncing worked just fine. After i dont know how much time i started getting errors that the syncing was failing. I tried to reconfigure the syncing properties but started getting the error server incorrectly configured. I scoured the net looking for answers following all the troubleshooting that I could find. One thing I notice is that when i choose I have an account it is supposed to load a key that i can use on my already synced devices but that never actually populates and it immediately kicks me to the user name password and sync key screen. This issue remained throughout the duration of all the troubleshooting below. Additionally I cant even create a new sync account on that pc as it fails everytime. I have done the following in a effort to resolve this issue. I created a new sync account using one of my other pcs I added a pc that was never on the sync account to it to verify it does it fact sync i uninstalled firefox 4 separate times deleting all the folders and even as far as the registry keys i tried using a lan connection vs wifi i updated windows My computer; I have a lenovo ideapad with windows 7 and 8 gigs of ram with a amd processor My LOG: 1308530082634 Service.Main INFO Loading Weave 1.7b1pre 1308530082645 Engine.Bookmarks DEBUG Engine initialized 1308530082646 Engine.Forms DEBUG Engine initialized 1308530082646 Engine.History DEBUG Engine initialized 1308530082647 Engine.Passwords DEBUG Engine initialized 1308530082647 Engine.Prefs DEBUG Engine initialized 1308530082647 Engine.Tabs DEBUG Engine initialized 1308530082648 Engine.Tabs DEBUG Resetting tabs last sync time 1308530082648 Service.Main INFO Mozilla/5.0 (Windows NT 6.1; WOW64; rv:2.0.1) Gecko/20100101 Firefox/4.0.1 1308530082651 SyncKeyBundle INFO SyncKeyBundle being created for 1308530086186 Net.Resource DEBUG GET cached: 0 1308530086186 Service.JPAKEClient ERROR Error acquiring channel ID.
