Several problems Rated 4 out of 5 stars

Three are three serious issues with this add-on on Linux:

1. It prevents Firefox from properly going full screen, e.g. when watching YouTube's HTML5 videos the Firefox button can be seen and the task panel doesn't go away.

2. It doesn't follow common mouse API conventions. The browser window should only close after _releasing_ the left mouse button, not when you press it.

3. It doesn't forward mouse clicks to the free space of the Tab bar. Without this extension when you double click it, Firefox will maximize/unmaximize. With this extension installed, double clicking opens a new tab.

Hopefully these issues can be fixed. I've temporarily disabled the add-on because it inconveniences me way too much at the moment.

Firefox upper left button and minimizing/closing buttons upper right remain visible in videos during full screen mode. Otherwise very good extension.

Works pretty well! Lots of customizations. Only if the "Minimize, Maximize and Close" buttons would look more native, then it would be perfect!

Addon mostly works great. I use the button next to the add tab/close tab buttons in order to drag the FireFox window around on my touchscreen device. But there's a weird aero-glass-like line at the top of the window that I can't seem to find out how to turn off?

Been more than a year since I tried last and all my previous issues with it are gone. Lets me configure to behave exactly like I want and gets back that precious screen real estate.

Works great on Ubuntu/Linuxmint Rated 5 out of 5 stars

This is one of those must have add-ons for small screens (e.g., netbooks). It offers many options to customize how the menu and titlebar are displayed. I've installed the newest beta version 2.9.1rc1 at http://tiny.cc/darth_moz (HCTP > New) and so far there has been no bugs on the latest Ubuntu and Linux Mint OS. Many thanks to Darth Madara.

Thank you! Rated 5 out of 5 stars

If you're on a laptop or don't otherwise have a lot of real-estate, you can recover some of that unused caption bar space by hiding the main menus, and make the toolbar buttons and tabs smaller as well. More pixels for you!

Great BUT... Rated 3 out of 5 stars

Works great but I have a 1 pixel white line at the bottom of all webpages when the menu bar is disabled and the window is maximed. How do you get rid of that? It's not there in fullscreen mode or windowed, only maximized.

Great extension!!! It is very flexible. Maybe one improvement in order to help saving space is to create an option to put the Firefox logo instead of "Firefox" label currently located in the top left corner of the browser.
Very good job!!

I made a previous comment which I've now deleted as I was being an idiot and didn't check all the options. Works beautifully on KDE.

Thank for the great job...
Is it possible to include more themes to the min/max/close buttons? (maybe "box-like buttons" like chrome)

如果能在"選單>自訂"內加一個"標題列"來控制標題列的顯示設定就好了。

still an outstanding addon Rated 5 out of 5 stars

btw since Australis have had an ironic glitch thought to be a broken feature in hctp that when clicking on the floating menubar menus (hovering over tabs) the #tabbrowser-tabs gets pushed down a row to make room for the titlebar where the menubar will then sit while menus are open - turns out the fix was to goto about:config and type "titlebar" then change the value of "browser.tabs.drawInTitlebar" from true to false

Great add-on, but in Firefox v33.1.1 the window cannot be dragged by the titlebar. Rated 3 out of 5 stars

Great add-on, but in Firefox v33.1.1 the window cannot be dragged by the titlebar. It can be resized but not dragged. All the open Fx windows stay stuck in one place.

I played with all possible options. No go. I also disabled other add-ons to rule out cross interference. Still no go. The bug applies to all the different titlebars the add-on provides including the "No (Fx default)".

Also, I had to do some extra styles for the options window because it does not gracefully theme in dark themes. The font-color stays dark (and unreadable) in some elements, mostly radio button labels and info labels.

Please fix because, otherwise, the add-on is awesome! Until then, it's a deal breaker.
