Firefox 3 was downloaded by more than 8 million users in 24 hours and it might well go down as the most downloaded software in 24 hours !
India’s contribution in the above 8 million was 226K and US was the highest with 4632K.
Talking of new features in FF3, Alex Faaborg, the user experience designer who worked on Firefox 3 has a very detailed post on the new UI features here
Below are 2 unique features in FF3, which I haven’t seen in hundreds of posts that cover the new FF3 features.
Scrolling using Spacebar
If you are keyboard junkie, I am sure you too will love this feature.
Till now, If you intended to scroll a web page, you either had to enable the Caret Mode (F7) and then scroll the web page or use the keyboard
Page up and
Page down key.
The first option isn’t that straightforward and the second one for some reason wasn’t always working reliably on FF2. Even in FF3, scrolling via Page keys doesn’t work properly.
However in FF3, you can easily scroll using the "Spacebar"
Spacebar - Scrolls the page down Shift + Spacebar - Scrolls the page up
Reopen/Undo Closed Tab
Tabbed browsing keeps your taskbar clutter free and also makes you more productive.
However you might also end up closing tabs (browser pages) which you did not intend to !
FF3 has a new feature using which you can quickly reload a closed tab. All you need to do is press Ctrl + Shift + T
Ctrl + Shift + T - Reopen closed tab / Undo Close tab operation
The shortcut is also kind of easy to remember since Ctrl + T is used to open a new empty tab.
Also FF3 does not just reload the last closed tab; in fact it maintains the history of closed tabs.
If you continuously press the Ctrl + Shift + T, you can reopen all the closed tabs in the session (the most recently closed is reopened first)
