This is more an issue with Dreamweaver than it is with Firefox.

You probably need to direct your question to Adobe Support if the following doesn't fix it.

In Dreamweaver you need to set up your browser preferences to say what browsers you want to test your web site in.

Here is a link to a particular page that might help (but it depends on your version of Dreamweaver)

Thanks for attempting to help with my connection problem. I still cannot connect using the firefox browser. I do have firefox listed as my primary browser, and have checked my website connection. They are not the problem. I was able to get around the issue by using the abobe text lab which my version of dreamweaver offers... I registered and was able to test my web pages there. It's not the same as it was during my website creation class at the university, but I can see a browser version. Just not firefox.... I don't know why it doesn't work, and unfortunately this is not the first time I've had a problem with the firefox/verizon mix.... thanks for your help. Guess I just can't solve this... Maryanne
