chwb2 doesn't make any effect about opt HOT 6 CLOSED

what would be the line to put into my bspwmrc or other config file to get the double border for all types of windows, from URxvt to Firefox?

There is no answer to that question because your question is incorrect.
As neasade said, chwb2 require that you pass the window ID of the window to affect in argument. For example:

 chwb2 -O 000000 -I ffff00 -i 3 -o 1 0x23

If you want to apply that to all windows, then you have to run this command one time per window you have, or script it, like this for example:

 lsw | xargs -n1 chwb2 -O 000000 -I ffff00 -i 3 -o 1

One problem you'll have is that the borders will look bad when you move the windows. This is because the internal border is drawn using absolute coordinates from you desktop. This is not a bug, just the way it works. When a window move, you have to redraw the 2-border pixmap (that is how 2bwm does it).
So to answer your question, you need to find a way to run a command whenever a window move, get its window ID (hint: use pfw/lsw) and run the chwb2 command with the window ID as the last argument.

Hope that helps, cheers

The arguments following your example should be window IDs to draw on

Thank you for your answer man! really appreciate that but I do not completely understand, what would be the line to put into my bspwmrc or other config file to get the double border for all types of windows, from URxvt to Firefox?

Thanks, sorry for being annoying

Closing as it is not an issue but misuse of the tool.

Hello, well thank you for your detailed reply, sorry for this late reply but I was studying for exams...

Well it creates borders when I run this command:
lsw | xargs -n1 chwb2 -O 000000 -I ffff00 -i 3 -o 1

but it also throws out a bunch of "errors" maybe? Also I can't increase my double borders size...

I'm back to you because I don't really know how to handle this output...

thanks for the high quality assistance ;)
