My add-on https://addons.mozilla.org/en-US/firefox/addon/categorize/ combines bookmarks and tab-management. It lets the user group bookmarks into sets that a user can open all at once or singly. This approach almost completely eliminates the need for an address bar.
Another interesting feature of the add-on is that it unifies bookmarks and web-search. The two seem totally disparate but they can be integrated seamlessly in a very cool way. Check http://techuser.net/beyond-chrome.html for an overview of the approach.
The Firefox teams seems to no longer care about add-ons and add-on users. I am an Add-on author. I submitted an updated version of my addon for Firefox 8 on October 27. Twelve days later the new version is still sitting in a sandbox waiting editorial review. With a new release happening every 6 weeks this kind of behavior is inexcusable and will likely drive people away from Add-ons.
Known problem with the compatibility system, and Mozilla plans to address it in the near future by improving the notion of compatibility, as well as adding the ability to quickly mark an existing version of an addon as compatible when it doesn't need changes.
I disagree. The folks at Mozilla are not so quietly encouraging developers to get involved in the alpha and beta releases to ensure that things do work on day one of a release? How much work was done up to October 27 ensuring that your add-on was ready to go?
Firefox 4 is a memory hog compared to Firefox 3.6. Worse, it leaks memory like a sieve. After a bit of browsing, it is using 350 MB with just a single tab open. Firefox 3.6 uses half that much memory on the same machine.
The other day, I discovered a Firefox nightly using a gig and a half of memory after some light browsing; after some investigation it turned out that had a few hundred meg allocated immediately after startup (having loaded only about:mozilla) and it allocated a few hundred more when I opened and immediately closed the bookmarks and history menus.
Turns out, in Safe Mode it was perfectly well behaved, and after hitting the 'reset all preferences to defaults' button, Firefox not only takes less memory, but is snappier too.
I beat the 350 MB by going to the Atlas Obscura website. Firefox managed to use up 550 MB with only a single tab open. This too after a clean start. Firefox just keeps on leaking memory when the Atlas Obscura website is open.
I hate saying this but Firefox 4 is shaping to be a disaster of epic proportions. The Javascript benchmarks are all nice and good but dear Mozilla folk you people also need to write a garbage collector for your implementation of Javascript that actually collects garbage.
No, no, no... definitely not virtual goods in the sense that you linked to... that is a whole other beast and I have been in complete awe at how much the virtual goods market has grown (first starting in the Eastern hemisphere).
Virtual goods such as web apps and services. Blogging apps, productivity apps, etc.
