I found today that there’s also a setting you can change to keep all windows resizable. That way you can at least drag the adjust the size manually. Here’s how to go about it.
- Type ‘about:config’ in the address bar to get to the configuration screen.
- In the search box, type ‘dom.disable_window_open_feature.resizable’.
- This will filter the huge list of settings down to only the one you’ll need to change.
- Right click the only line now left and select ‘toggle’ to set it to ‘true’.
