1. Speed dial
If you have ever used the latest Opera browser, you must already be aware of speed dial. Inspired by Opera, someone wrote this add-on for firefox which serves the exact same purpose. The snapshot shown below should tell you, what speed dial does.
You can set up your default new-page to be a page which shows nine smaller pages as shown above. Most of us who don’t want a blank page as a default new-page, end up setting some site (like Google or gmail) as the default page. But it has a problem. Though most of the times, it’s okay, for Google.com to show up every time we open a new page, sometimes we really don’t want that to happen. Speed Dial gives you the advantage of nine pages to go through in one go. I guess you get the idea! I found it convenient and cool.
Do you think it would be great if while reading anything online, you come across a word about which you have no clue, and all you have to do to find out what that word means, is to click on the word? It would be a cool thing, right? And here you go, it’s possible. Except that, instead of clicking over any word, you need to do an Alt+Click. Big deal! This is made possible by the Answers add-on. Install it and you will never again have to copy a word and paste it in Google or Dictionary or Wiki to find out what it means. Really cool.
