Is this command correct?

i3-msg "[class='Firefox'] move position center" I'm calling this from a floating xterm, and it's the xterm window the one going to the center and not the floating firefox.

This bug has been fixed in the development version and will be included in the next release (after 4.8)

There are two problems here: 1. Not every command supports the usage of criteria. `move position` is on of them. 2. i3 only understands double-quotes. So you have to use single-quotes to quote the whole command and double-quotes for the criteria If you only have one Firefox window than this should work: i3-msg '[class="Firefox"] focus; move position center' ---- If you have multiple Firefox windows, i3 will just try to move one of them, not necessarily the one you want (multiple calls will always select the same window). In that case you could go by `title` or `con_mark` instead of `class` to select a specific Firefox window.
