|Via the Firefox website|
Here are some things I like about it:
- "Pin" tabs of websites that you use frequently so that they're always open in your browser.
- Right-click in the top tab bar to re-open a tab you closed.
- Gives you the option to restore your session if the browser has to shut down unexpectedly (never lose your spot in your web searches again).
- Customize it with themes and add-ons that work for your life.
