Sort tabs advanced oleh monomon

Web extension for sorting tabs by various criteria:

• url
• domain
• title
• last time of access

I found myself frustrated that it's not possible to sort tabs by domain in Firefox Quantum.

Then, I discovered that sorting tabs by access time is kinda useful. You can push the tabs you use often to the top, sinking old ones saved for later.

## TODO

• Improve UI
• Improve icon
• Performance
