I have never learned the keyboard shortcuts for Firefox – specifically switching tabs. I get frustrated if I need to do a lot of switching.

But! There’s an excellent chart of the shortcuts for Windows and Tabs.

Go one tab to the left is Ctrl + Page Up, to go one tab to the right is Ctrl + Page Down. To close a tab is Ctrl + W. There are many other operations. (I’ve printed out the Windows and Tabs section for my office.)

The other thing I need was to go directly to the address bar, so that I can copy the address. That’s F6, but there are two other options, listed in Miscellaneous.
