Fixes a bug in 3.1 that caused the toolbar button to stop working.

Version 3.1 lets you set shortcuts to skip back to the second- or third-most recent tabs. Set them through the Manage Extension Shortcuts menu in the Add-ons manager. By default, these shortcuts aren't set to anything.

Finally adds support for remembering previous tabs if you close the most recent. Pressing the shortcut after closing the most recent just goes to the next most recent instead. Woohoo! This makes things work better with container tabs too, since changing containers opens a new tab and closes the original; this would previously break the chain and the shortcut but now works just fine.

Now you can set custom keyboard shortcuts! Open the Addons settings page in Firefox and hit the preferences button next to Most Recent Tab. Requires Firefox 60.

Version 1.1 features behind-the-scenes updates to make Most Recent Tab functionality usable from other addons. Developers of other addons can trigger the action by sending a message using the runtime.sendMessage() API.

Welcome to 1.0 of Most Recent Tab.

I've ported it to the new WebExtension system so it will start working again.

Unfortunately there isn't currently a way to customize the keyboard shortcuts within WebExtensions, so everyone's keyboard shortcut is back to ctrl-shift-1 (Windows) or cmd-shift-1 (macOS).

New in this version is a toolbar button that does the same thing as the shortcut. You can get rid of it using the customize feature of the menu.

Most Recent Tab should now work as expected when you have multiple windows.
