Purportedly Browserstack can be used to do "local testing". When using Chrome or FireFox this default supported and should work transparently.
There is not a lof of documentation on how this should work so this makes me wonder if this is done in practice.
For example, I have a private website that I can only reach using the proxy server that is also used to access public URL's. I think that Browserstack considers this website public somehow and so it fails to reach this website.
Also I noticed - since installing the Browserstack extension - FireFox is crashing like there is no tomorrow.
This also makes me wonder how well this works in practice. I can't imagine any serious testing being done with combination of FireFox/Browserstack and local testing.
Is Browserstack used in practice for testing private servers? How is this done?
