This Firefox add-on arranges tabs in a vertical rather than horizontal
fashion. Vertical Tabs Reloaded is a fork of [Vertical Tabs](https://addons.mozilla.org/firefox/addon/vertical-tabs/), which was discontinued. The original project is heavily inspired by the Tree Style Tab add-on.

Source Code & Issue Tracker: https://github.com/Croydon/vertical-tabs-reloaded

Installation: [![https://addons.mozilla.org/firefox/addon/vertical-tabs-reloaded/](https://addons.cdn.mozilla.net/static/img/addons-buttons/AMO-button_2.png)](https://addons.mozilla.org/firefox/addon/vertical-tabs-reloaded/)


## Features:

 * arranges tabs vertical
 * ships 5 different styles for the tab sidebar (+ option to use Firefox/thirdparty add-ons style)
 * hides tab sidebar in fullscreen mode (toggleable)
 * hide/display manually the tab sidebar at any time with a hotkey (customizable)
 * display the tab sidebar either on the left side (default) or on the right
 * display the tab toolbar at top (default) or at bottom
 * compact mode: hide text labels on tabs for a minimalistic tab sidebar (opt-in)
 
 
## Goals:

 * Minimalist implementation.

 * Native look and feel and ability to customize if wanted.

 * Readable, maintainable and robust code.

 
## Support

Only the latest Firefox version is fully supported. Compatibility with the latest [ESR version](https://www.mozilla.org/en-US/firefox/organizations/faq/) will not get broken on purpose, but it might be necessary to do so sometimes. Pull requests fixing compatibility with the latest ESR version have a good chance to get accepted. Pull requests concerning other versions as the latest Firefox version or the latest Firefox ESR version will not be accepted.
