Why not make it for FF3.6 and TB 3.11? Rated 4 out of 5 stars
FF 4 and 5 are horrendous and many of us are staying with the best browser on the planet- FF3.6. Why do developers not make add-ons compatible with it? In fact, with the horrific new "rapid release" strategy all developers may as well make their number as infinite...**Edit** I am sweeping the Thunderbird catalog for good add-ons and this was also listed as a TB add-on. It is becoming abundantly clear that catalog is a royal mess. Most of them have been abandoned and have not been updated in years( on average 2008.) Since they just released TB5 this has added to the carnage. Being able to check compatibility and updates is a a major issue and it would really really help if this was also compatible with TB 3.11. If there is no major technical issue preventing it from working with the older versions that many users are rolling back to this add-on could be quite helpful. Of course if it all worked I would go in there and boost my review and add some stars. Thank you!
**Edit 2** I came back and I like how you were honest and explained the reasoning behind things. Even though I am running the competing add-on I think good old fashioned integrity is worth boosting the rating anyways. Thank you!
Yes, there are major technical reasons this won't work with earlier versions.
I chose specific versions in the "Works with:" section because the add-ons manager was totally rewritten starting with Firefox 3.7a5 (around May 1st 2010 specifically) and this will only work with the new manager. The same goes for Thunderbird and SeaMonkey. I doubt a single line of code could be used in earlier versions of Firefox/Thunderbird/SeaMonkey, so I would have to write another complete extension and somehow integrate the two. That won't happen. There was another extension called Update Notifier that may still work. I don't know since I don't have earlier versions of Firefox or time/interest in testing it.
