I use Firefox – whatever version that Ubuntu 10.04 LTS pushes. I don’t do beta testing – that is for the younger crowd.

Today, I found another extension that I’ll probably enable for shopping, but disable the rest of the time.

InvisibleHand

InvisibleHand is a browser extension that watches as you shop on 20-100 websites and suggests alternative, cheaper places to purchase the same item. When you finally get to a specific item page, it looks for that same item on all those other websites and show you where you can find it cheaper. It isn’t perfect, but WOW! For some items, you’ll see over 50% savings and for others, just a few dollars. Some of the suggested cheaper websites are not places that I’ve shopped before and for a few dollars, I’d probably go to NewEgg or Amazon first. Still, when Amazon isn’t priced right, seeing a $30 savings another company I’ve heard of before is nice. I found that most of the time, the alternative was exactly the same item, however, once it suggested the wrong model device, so definitely check that the suggested alternative really is what you want.

Firefox3 uses Internet Explorer settings from the Control Panel. This is just stupid. If I wanted IE settings to be used, I’d run IE!!!

For example, I have IE setup to be very safe for the “Internet Zone”. This is to prevent noobs who don’t know anything from causing my machine to be compromised by stupid surfing. I don’t want these settings shared between IE and Firefox. Why should I have to enable file downloads for IE when I only want file downloads to work in Firefox?

Thanks Mozilla team. Genius at work.
