I just downloaded the new Google Chrome for Mac beta. I like to clear out my cookies after each time I quit the browser, so tracking information and so on doesn’t hang around any longer than it needs to.

On Google Chrome for Mac, there is no built-in setting to force all cookies to be session cookies, but you can use this hack to achieve the same thing. After launching Chrome at least once, then quit it and run the following commands in Terminal:

rm "~/Library/Application Support/Google/Chrome/Default/Cookies"
ln -s /dev/null "~/Library/Application Support/Google/Chrome/Default/Cookies"

The first command deletes the cookies file and the second command creates a symbolic link, so that anything dropped in the cookies file goes to /dev/null (i.e. the cookies gets deleted and not stored once you quit!)

UPDATE 2010-01-29: JeanVal reports in the comments that this process works on Chrome for Linux too. The Cookies file is stored at the path ~/.config/chromium, so just adjust the commands above to fit that path.

Firefox on the Mac is, well, it doesn’t always fit in quite as well with the Mac as it could – and it feels like that’s always been the case.

Firefox 3 is meant to start changing that, and making Firefox feel like a first class citizen on OS X. Having heard Jacob’s singing praise for the beta’s integration with GTK on Linux, I thought I’d download the Mac build and give it a try.

The first thing you’ll probably notice is real native buttons. Instead of Windows 95-style boxy buttons, native Mac buttons are now used, unless the website specifies specific button colours, in which case those colours and styles are used on the standard boxy buttons (exactly the same as Safari 3 now does).

There’s also a new theme available, called Proto. It doesn’t ship with the beta, but is linked to from the welcome page you get. And this is what it looks like:
