It works with Linux too. You just have to change that on mozilla.org website. Assegnate 5 su 5 stelle

This add-on is great and it's a very small twist you have to do to install it in Linux to. Just download the windows file anyway, change the name of it (just the mentioning of "windows" part with "linux"), and install it manualy from the Add-ons manager interface.
This is posible at least since 2 years ago.
Therefore, I don't understand why are you not mentioning this? You are supporting a free software after all. Why not Linux to?
It's millions of Linux users (and growing) that can use it to.

「Cyberfox」などのスタイルとの親和性を高められるので、thunderbird の特異性を改善できます。 Assegnate 5 su 5 stelle

「Cyberfox」、「Pale-Moon」で “上部左端に生じる 「Home」tab” を thunderbird に生成する add-on です。

「Cyberfox」などのスタイルとの親和性を高められるので、thunderbird の特異性を改善できます。
この「Home」tab によって、「タイトルバー」が非表示化されるが、「Home」tab の機能と重複する「メニューバー」の非表示化もできるので、画面をスッキリと再構成できます。
「Home」設定には、表示色、サイズなどの Option 機能が用意されています。
大変、気に入りました。
推奨します。

【要望】
「Firefox」、「Cyberfox」で利用できる「The Fox, Only Better」の “hide機能” を好みます。
以前、その作者に「thunderbird」への対応を要望しましたが、thunderbird への関心が無いようです。
ぜひ、同様な “hide機能” の付加を検討願います。

Excellent addon Assegnate 5 su 5 stelle

Works great in thunderbird 31.5 on Linux too.
Just download the xpi via firefox, then "install from file" in Thunderbird.

Thunderbird Looks Much Better With Hide C. Titlebar Plus Lite Assegnate 4 su 5 stelle

This add-on helps well to make Thunderbird looking better. But Thunderbird 31.3 appears still bullheaded: if in about:config the item "mail.tabs.autoHide" is set to true the titlebar is still there. And with "mail.tabs.autoHide" set to false there is still an empty useless annoying blue bar in the unmaximized window under the topmost bar.

Funktioniert nicht richtig mit Thunderbird 31

FIXED in version 1.3.7 (see "Versions" link)

(Tab-bar was slighty displaced off top-edge)

The firefox version is amazin, but can we have this thunderbird version for linux too?
Edit: there seems to be some type of support for it, but I can't install it by default... hmmm

Works with Linux too!! Awesome! Assegnate 5 su 5 stelle

Dear developer, this addon works for Linux too. I have tested on Kubuntu 13.10 64bit with TB 24.2. Excellent addon. 5 stars, Please make it available for Linux as well. Rename the xpi file , replace windows with linux and install.

Linux Assegnate 5 su 5 stelle

I love this add-on and fortunately it works perfectly under Linux too.

Just download and rename it from hide_c_titlebar_plus_lite-***-tb-windows.xpi to hide_c_titlebar_plus_lite-***-linux.xpi. Install manually from TB.

Thank you VERY much for this great addon! One little thing isn't perfect - I have sent a posting in support-forum about this ...

Love it! Assegnate 5 su 5 stelle

Thank you!!!!

Love it and feels so much more in style with the general Moz suite.

One thing I'd love to see in a future version: auto-hiding of the 'old/original' menu button from the toolbar. The button is now no longer needed and just a waste of space. However if I manually remove it, the menu won't display below the button provided by this plugin.

I've actually managed to do this myself by adding the following to userchrome.css:
#button-appmenu {
display: none;
}

Makes Thunderbird menu much better Assegnate 5 su 5 stelle

This add-on gives the new Thunderbird look a much nicer appearance. The Firefox-like menu button is much nicer than the ugly original one. And the floating menu bar gives quick access to all items what I miss in the new Thunderbird menu.
Thank you!

Excelent addon, app button in Thunderbird is not the style of mozilla apps, only one detail, there a "visual bug" with TTDeepDark Theme, the new button is over the tabs in the left side.

Great add-on! Please add RTL support Assegnate 5 su 5 stelle

Great add-on!
Using it forever on Firefox and love it Thunderbird.
Please add support for Right-to-Left interfaces (placing the icon on the top-right).

Thanks & keep up the good work!

Thanks for adding app button like firefox, only one suggestion that it opens/flairs horizontaly while arrow shows downward can you give us option to flair menus downward or horizontaly and accordingly arrow should be placed. also though very nice and prompt work can you replicate firefox style app menu?

Darn!, looks strange first, quickly appears as a brilliant idea. I'm (still) with XP(sp3) and no problem, just feels less heavy. Splendid. Nice work.
