Steps to reproduce:
1. Generate an HTML page with 10k of <a> elements
2. Modify <base> element 1k times
Actual results:
Page takes 20+ seconds to load
Expected results:
Page should load in under 1 second
Forgot to mention, in other browsers - page does take less than 1 second to load. This issue is unique to Firefox.

The reason why we are slow is because, when we change the baseURL, we remove the list of Link elements from nsIDocument and then we reinsert them all again.
