Tor Browser 4.5a5 is available at: https://people.torproject.org/~mikeperry/builds/4.5a5-build6/
This release will be the last alpha in the 4.5 series. We hope to release 4.5-stable in mid-April.
This is my first look at the 4.5 series ...

Other regular tests all seem OK and it works with Torsocks. Nice job!
Hmmm.
Firefox seems to be using quite a bit of CPU. CPU usage is consistently 10-20% and there are about 100-200 more context switches per second than when using TBB 4.0.6. vmstat output attached. FF version is 31.6.0 in both, OS is Debian 7.8, processor is Intel(R) Pentium(R) CPU B950 @ 2.10GHz, system has 4GB of RAM and generally doesn't swap.
Nothing else was happening on the box at the time, and stats were generated a few minutes after TBB had started in each case. I haven't used earlier versions in the 4.5 series so I can't compare this to older releases.
Please let me know what other information would be helpful.
This was consistently reproducible for most of the last 24 hours but has now stopped. When it stopped I noted that HTTPS-Everywhere and NoScript had been updated, and a restart confirmed the new versions (5.0.1 and 2.6.9.20 respectively). Maybe the update was the cause of the activity? Is this auto-updating of add-ons expected?
