All below were fixed; Thanks.
There is one problem: When I want to start timer (with a previous set time) it does not work right 1st time: it gives timeout right away! When I do it again, it works!
I have FF 3.6.3 and TF 0.8 (updated). (I remember it did not do this when I installed it 1st time)
Please fix it.
