Need to control timeouts for some browsers

[nm777]

We have applications that are sometimes slow to launch for some users. Having the ability to control the timeouts would be very helpful in these cases.

I'll create a pull request for this.

Thanks!

Is there any chance of reviewing/merging this one?

Thanks!
