Let’s start my first post on MMTC planet.
As you may know, my first goal was to develop an extension which enable us to paste an URL into the download manager. This action should start the download of the file represented by the URL. The extension was just the first part, then I planned to create a bug on bugzilla and submit a patch on the Firefox trunk. The bug is filled (bug 506881) but as you can see it was marked as RESOLVED WONTFIX :( I will finish my extension anyway but I had to find a new project.
So I decided to work on tabs.
I decided to use the sidebar and remove the traditional tab bar. Let’s imagine that you have less than X tabs (X will probably be calculated from the size of your screen), Firefox will display a sidebar with websites thumbnails. Moreover, the « new tab » button will have a search field to create directly a tab with the search results.
Beyond a threshold, the tabs will look like a tree (see the extension TreeStyleTab), without the thumbnails.
Those ideas are from Alexander Limi, a Mozilla employee. I encourage you to read his article Reinventing tabs for the browser to better understand the design purposes.
If I have more time, I plan to add « work spaces ». It’s like a box where you store a set of tabs, for later use.
