I have already installed the script from the Github and I also run the 2. script (generated to ~/.local/bin directory) with the "-x" option), but it doesn't work.

How can I fix the problem ?

I use Firefox 57 (Quantum) on Linux Mint Debian Edition with Xfce desktop environment. (The xdotool package was installed after first run of the sh file generated to ~/.local/bin directory. After that I run this script again with success.)

Can You help me with some tips / advices to make this addon workable on my system ? (If you give me a mail-address we could talk about that there.)
Thx.

Does exactly what it's supposed to. Leaves a small 4 pixel high bar at the top so you can still click and drag the windows around. Thank you!

The main reason to hide title bar for me is the possibility to not care about Y direction of mouse pointer when I clicking on tabs. Because, in Chrome its tabs start from the TOP of the screen. BUT!!! In this add-on there is a still 1 pixel distance between the top of the screen and the tab!! And I must care about Y position of a mouse pointer to it will not be at this 1 pixel line on the top, it must be little bit down to I can click on tab. And this is VERY bad.

给我看看源码。

挺好用的，就是链接速度有点慢。
