 I'm using TB 1.4.0 with FF5 (5.0+build1+nobinonly-0ubuntu0.11.04.2 from
 Ubuntu). Recently I noticed that the system load was very high when I
 start Firefox. So I have an empty session with an empty start page. When I
 start FF it takes lots of seconds until the FF window shows up. During
 this time the cpu load is ~100%.

 I did a git bisect today and found out that commit
 81624d96f2427bf2f1be7893d0bd08c1f9b38f61 causes the problem. Within the
 file {{{src/components/external-app-blocker.js}}} this was added: {{{ ||
 method == "getTypeFromURI"}}}. If I remove this and install TB, it starts
 without any huge load or large startup time.
