Firefox is the most extensible web browser around but you don't even need to install any add-ons to take advantage of the numerous shortcuts that make tabbed browsing even better.
Over at MakeUseOf, the software and technology-centred blog, they've put together a guide to being more productive with Firefox tabs, among the great add-ons they suggest like previously covered New Tab King and Tab Navigator, they also highlight some great built-in shortcuts — seen in the chart above.
Using the shortcuts expands the versatility of tabs without a single bit of memory bloat to your Firefox installation. You'll definitely want to learn the shortcuts above as well as one they missed — using CTRL+Page Up and CTRL+Page Down to move up and down through your list of tabs.
Have a favourite shortcut in Firefox, tab-related or otherwise? Let's hear about it in the comments.
