Find your way around the new browser
Step 7. A new feature called Panorama adds a twist to bookmarking. You can create groups of tabs for visiting later. This helps keep the tabs area clutter-free and organised. Tap the icon on the right of the tab bar, then choose Tab Groups. This will display all your open tabs and let you organise them in different ways.
Step 8. To form a new group, drag any tab out of the main group and drag other tabs on top of it. To leave Panorama mode, simply click on a tab. The tab and all its associated tabs will launch, but none of the others will. To open another tab group, re-enter Panorama mode and select a new tab.
Step 9. Firefox 4 includes a new Add-ons Manager, making it easier to find and install add-ons. You no longer need to restart the browser following their installation either. Click the Firefox button and choose Add-ons. Note that there are four groupings: Add-ons, Extensions, Appearance and Plugins.
Step 10. Because many of us use more than one PC, Firefox Sync can be used to synchronise open tabs, history, bookmarks, passwords and forms data. Click the Firefox button and choose ‘Set Up Sync’. If you already have a Firefox Sync password, enter it now; new users will need to create an account, then set up options.
