Chromin Tab Behavior

I love to make my Firefox like Chrome, and I think Chromin Frame is a very good add-on, which make firefox frame escape from system boring frame style. But when I try to double click or drag the tab-bar, I feel strange. In Chrome, space in tab-bar behave same as caption bar. This different with Chromin Frame, when I double click tab-bar a new tab appear, when I drag nothing happen. So I write this add-on to make the behaviour of tab bar same as ChromeDeveloper Comments Hi all, I am a novice add-on developer and this is my first add-on, I know this add-on effect may not obvious, as it need to use together with other add-on, but if using the following three add-on: 1. Chromin Frame by Zero Fire: https://addons.mozilla.org/en-US/firefox/addon/100912. Chromifox Basic by tcmediatech: https://addons.mozilla.org/en-US/firefox/addon/87823. this addon I think firefox will then become more like a Chrome, funny didn`t it? Please feel free to add comment, I love User interface design, ad love to gather idea on this topic. I know this add-on is very minor and cannot work for any surprise feature, but this is my first try, so please comment if you like this or not. Thanks
