In vsn 6.0.2 how can I paste a link into the body of a Yahoo e-mail and have the pasted result appear as a link?

Question

o/s Windows XP Home
vsn of Firefox 6.0.2
Step 1) open firefox
Step 2) copy link from address bar into clipboard
Step 3) compose message in Yahoo
Step 4) paste contents of clipboard into body of the e-mail
result: the pasted value does NOT become a hyperlink
<on same pc, with same contents in clipboard>
Step 5) open IE
Step 6) compose message in Yahoo
Step 7) paste contents of clipboard into body of the e-mail
result: the pasted value becomes a hyperlink ... the fact that the link becomes a hyperlink in the IE browser makes me think that there may be something in the Firefox browser that is controlling whether the pasted value becomes a link.
I'm not sure, but I believe the update to firefox 6.0.2 was with the past few days.
I'm not sure, but I do not believe the symptoms from steps 1 - 4 were present a few days ago
Questions:
1) could this feature have been introduced in 6.0.2?
2) I would prefer it if the pasted value would become a
hyperlink when working in firefox; what steps do I need to take to make this happen?
Thank you

Now Tony, I know you can't hear my tone on a forum post but I was not complaining, simply stating facts . This change brought several people in my office to a grinding halt in a long established workflow that is really rather simple (and I thought was already assumed from the original post above ):
1) Select a set of records in FileMaker Pro 12 and export only their e-mail addresses as a CSV file.
2) Open that CSV file in Excel.
3) Copy the column of e-mail address.
4) paste into the appropriate recipient field in Mail.
5) Send
If I were to complain it would be about Apple's typically opaque approach to updates. There is no granular explanation of why changes were made or even "what" changes were made.
Complaining is futile since Apple is Apple and is unlikely to change, but sometimes it is cathartic to "shout into the void" .
I had thought about doing something with a formula in Excel and your suggestion was simple and helpful. Again, however, it is only a workaround for a long established helpful behavior that Apple has inexplicably broken/removed in Mavericks Mail.
I, and the other posters here, would love to have the capability back rather than have to add previously unneeded steps to our workflows.
Ultimately we may add scripting steps to the FileMaker side to export the address lists with commas inserted already if Apple ends up having permanently removed this feature.
