MozillaDeveloperPreview 3.7 alpha 4

Few weeks ago Mozilla released an alpha version of Firefox and I decided to try it. It's MozillaDeveloperPreview 3.7 alpha 4.

I did a quick comparison for startup time between Firefox 3.6.3 and this preview. My firefox opens with 3 windows and a total of nearly 20 tabs:

This new version starts much faster, but it's still not fast enough for me. I like Safari on Mac because it starts very very fast, but when Firefox is loaded, it's fast… while Safari freeze for few seconds from time to time.

• Shutdown is also much faster.
• Page rendering seems faster than Firefox 3.6.3.
• Client identification (with SSL certificate) does not work anymore.
• Acid 2 test passed.
• Acid 3 test: 94/100.

There is something that has not changed yet, on my Mac Firefox is still using between 15 and 20 % of the CPU while it's open, even when I'm not looking at Firefox (and it does not look like any of the pages that are open are doing some fancy CPU eager things).

The WordPress plugin I'm using against SPAM prevents me to login when using this preview version 😕.
