User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.2) Gecko/20070219 Firefox/2.0.0.2 Build Identifier: All Builds >= 1.5 When I upgrade TB to any version >= 1.5 and "Edit as New" and then send a HTML email containing embedded URI images the message never gets sent. TB will try and attach these embedded URI images, like: <IMG SRC="http://www.nwa.com/images/grey.gif" WIDTH=100% HEIGHT=1 HSPACE=0 VSPACE=0 BORDER=0 ALT=""> BUT it never completes attaching the image and it never times out and gives up. Reproducible: Always Steps to Reproduce: 1. Edit as New a html email with URI references to images. 2. Click Send email, TB will say attaching abc.gif 3. Email is never sent, just hangs until you hit cancel. Actual Results: Email is never sent, just hangs until you hit cancel. Expected Results: Email is sent. Problem does not occur in TB versions 1.0.7 and lower.
