I was trying to strace an iceweasel like this:

strace -e trace=connect iceweasel

And I was expecting to see calls to connect when I load new pages. Surprisingly, there weren't any.

Why so? Am I using strace incorrectly or why doesn't it show calls to connect which obviously must happen.

Iceweasel creates a lot of child processes, which then do the connection to remote web servers. You have to advice strace to also trace childs, when the binary executes the fork() system call to create a child.

Use this command:

strace -f -e trace=connect iceweasel
