Switch to Last Tab por emvaized

Fast and lightweight extension which allows to quickly switch to last accessed tab on toolbar icon click, keyboard shortcut or when closed active tab.

Features
- No complicated code for tab tracking, just pure and straightforward sorting on each call
- Works right after browser restart
- Adds a toolbar button which switches to last tab on click
- Provides a keyboard hotkey (default: Alt+Q, change on about:addons shortcuts page)
- Shows a small badge when switched to previous tab, which will be removed once you switch to another tab (can be disabled in settings)
- Focus last active tab on current tab closed (can be enabled in extension settings)

There are many extensions that do the same, but they use complex code, storing their own history of tabs. There's no need to reinvent the wheel, when your browser already does that. This extension uses minimal code and only native functions to achieve the same result.

The project is open-source, you can view the code on GitHub.
