This is a really handy (and simple) extension, but the fact that it doesn't truncate or fade long page titles makes it really ugly!

Please allow long titles to either fade or add "..." at the end. Thank you!

is it possible for me to submit a pull request? I added a feature. Please contact me: temp954335@czxzyyyk.de

Thanks for providing and working on this add-on. To me it would become much more usable if it would automatically place tabs below marker tabs according to their tab-environment (work, ...).

Simple,useful,efficient extension deserving 5Stars.

It's simple but does what it's supposed to. No complaints.

Good job !
The best to replace All-In-One-SideBar. but with fewer features. I regret the opening/closing of the sidebar with mouse gestures

Good job. Lightweight. Font size is readable to me. What do I put in "Override Style Sheet" in order to get light text on dark background? Could you let me know, or else make this extension follow the dark theme that Firefox uses? Thank you.

I have tried all the Vertical Tabs extensions post-FF59 I could find, and this is definitely the best!
Simple, fast, does not mess with the opening and closing ordering of tabs and focus change, allows drag & drop of tabs between windows.

The speed gain on all FF tab operations compared to others extensions such as "Power Tabs" is really noticeable.

The only missing feature is a way to "detach" a tab into a new window (I have to use the tab on the top of the window, or create a new window and drag+drop the tag there), unless I have missed something.

Nice and simple Tree Tab

Tab Sidebarシンプルであること、それがとても良いです。
Default Style Sheetを見ることができるのもうれしい。
サイドバーに表示されたタブをマウスホイールで切り替えることもオプションで可能となりました。
ありがとうございます。

Exactly what I was looking for.

is it possible to hide the tabs on the top of the browser?

Great addon could you add the options on the right click context menu to bookmark the tab and copy it's url to the keyboard? Also it would be great if you could select more than one tab at a time using control or shift to be able to manage the tabs in bulk like move them close them etc but the action applying to all the selected tabs.

Thank you so much!
This reminds me about All-in-one Sidebar.
Very easy to handle Browserhistory and Bookmarks. Would be nicer if the opening button for the Sidebar was on the left side instead. Like a button in the left upper corner underneath the "back" button.
Keep up the good work.
