Diffie-Hellman minimum key size for different browsers

I am wondering if it is described somewhere what is the minimum Diffie-Hellman key size supported for each browser.

As I know, modern browsers do not allow decreasing this key to 512 key sizes.

As an example, the latest chrome supports 2048 keys and I'm not sure if it supports a key size of 1024. Could you share both with the browser version of the table and the min / max key size?

And one more question, if the apache key has a length of 2048, which browsers won't be able to use that key?
