Here are a few new tab tricks you may want to try and keep for Firefox.
- Double-click a tab to reload it. Created by Linh Phung, this Firefox extension does exactly as advertised: Double-click To Reload Tab.
- Need to display tab contents sequentially? Tab Cycler, developer by Greg Parris, transforms your Firefox into a web page slide show. Install it and right-click on a tab to start automated tab switching. Right-click on the tab bar and select Cycle Tabs again to stop it.

- Need to quickly check for some change in your favorite web mail or social network site or other pinned app tab? Peek, developed by Dietrich Ayala enables Alt + Shift + Number as hotkeys for a quick check of your app tabs.
