So I'm running Mozilla Firefox for awhile now and it's great...but now when I click on the little envelope deal up on the toolbar and go to "Read Mail", instead of linking me to Thunderbird for E-mails I get this stupid "sign up for MSN Explorer wizard" which I can't get rid of. I used to go right to Thunderbird now I have to access it via an icon on my desktop. My Internet setting in the control panel is set to Thunderbird as a default. Any ideas how to relink it to Thunderbird???
Maybe it's time to re-install both. Did you check with adaware and spybot sd? did you check your hosts file?
it sounds like the registry association just find an e-mail file, right click, open with, thunderbird, check the always open with boc....
setting thunderbird as your standard email client could help.... -->Tools--> Options--> General /// check Use Mozilla Thunderbird as the default mail application
