2. Catch-up features: Firefox’s new features are bound to let it catch-up with Chrome, especially in terms of the people switching over to new browsers in the blink of an eye. Sure, these changes are coming in a tad too late, but still, they’re worth watching out for. Some features that fall I this category include that of Firefox’s own app store, silent updates like in Chrome (which will make version numbers irrelevant), add-ons sync (for those running the browser on various computers and cuts down the need to individually install add-ons on every computer); and the option to read PDFs and other docs inline.
