Firefox 3.6.13 + Sync 1.7

Entered username and password okay. Received the sync key. While trying to connect I get an "unknown error" displayed in red in the preference dialogue, or "Error While Signing In" when I hit the Connect button at lower right corner of Firefox, if I hit that button I get "Sync encountered an error while connecting: Unknown error. Please try again."

This is from a home wireless broadband account, there are not any firewalls in place, and using NAT.

Thanks.

I noticed this error in the JS console: Error: uncaught exception: [Exception... "Component returned failure code: 0x80520012 (NS_ERROR_FILE_NOT_FOUND) [nsIXPCComponents_Utils.import]" nsresult: "0x80520012 (NS_ERROR_FILE_NOT_FOUND)" location: "JS frame :: file:///home/XXX/.mozilla/firefox/9da8ohi4.default/extensions/%7B340c2bbc-ce74-4362-90b5-7c26312808ef%7D/crypto-modules/WeaveCrypto.js :: <TOP_LEVEL> :: line 45" data: no]

Looking at the code, line 45, as indicated shows that the file "Services.jsm" is required. A little ggling makes me conclude that this is included in "Gecko 2" which is released only with FF4.0. So sync is probably not supposed to work with FF3.6.

Let's try to contact the developers...
