Been a long time user of firefox and recently have started using Orion, and so far loving the browser.
In firefox there is an option to select links on a page by just clicking apostrophe key (') (next to semicolon key) and we were able to type a couple of letters relevant to the link and select the link to open it. It's a handy feature as it allows to navigate the browser without using mouse or trackpad which is much faster and responsive in my opinion.
