Earlier this week, I wrote a Firefox extension to prevent duplicate tabs from opening. Reader Jimmy Fung posted a comment with a link to Firefox 2 and Flex: Launching builds in the same window. It makes my extension somewhat (alright completely) useless – but hey, I learned a lot about making Firefox extensions in the process! As I conveyed in the earlier extension post, the process was less involved than I probably imagined beforehand, and I’d suggest that if you think you have an idea for an extension, do not hesitate to add yours to the rapidly growing Firefox add-on ecosystem.
And, I always welcome comments on just about anything pertinent to the subject of a post, by the way.

Hi,
I don’t agree. I believe your extension is very useful.
I don’t one to always reuse the same window. I wanna to reuse same windows only on some URL’s.
By the way, I wanna to ask for a new feature. An option do set what urls prevent to duplicate.
Some urls I wanna duplicate (gmail.com =D), but one no (file:///C:/myproject/workspace/project/bin-debug/SomFlexApp.html)
Great work.

I tried your extension; it apparently had a problem with restored sessions on Firefox startup (maybe because the tabs are originally created with about:blank?). It would probably be good to exclude about:blank from the duplicate management, as well as allow configuration of which domains/URLs to include/exclude (kind of like the popup blocker configuration).
Thank you thank you thank you thank you thank you!!!
@Christopher – I plan on adding whitelist to the extension on the weekend. I will post a notice when I update. I to have notice the problem with restoring tabs as well as a problem with opening a folder of bookmarks in new tabs. I am currently excluding about:blank urls, but the problem is in how I am enumerating tabs when the DOM sends notification of a new tab. I think the best solution is to allow white listing of urls, as I have come across situations where I want two GMail or GReader windows open at the same time.
