Mozilla Firefox is a fast, full-featured Web browser. Firefox includes pop-up blocking, tab-browsing, integrated Google search, simplified privacy controls, a streamlined browser window that shows you more of the page than any other browser and a number of additional features that work with you to help you get the most out of your time online.
Mozilla Firefox is in the Web Browsers category of the Browsers section.
What’s new in this version: Version 17.0.1 fixed Font rendering issue in Firefox 17.0, Reverted user agent change causing some website incompatibilities and added First revision of the Social API and support for Facebook Messenger , Click-to-play blocklisting implemented to prevent vulnerable plugin versions from running without the user’s permission.
Mozilla Firefox has undergone an enormous rebirth over the past two years. Since Firefox 4 debuted in March 2011, the browser has been hell-bent on improvements. These have come in large part on the rapid-release cycle, which sees a new version of Firefox every six weeks. Many people like them, but a vocal minority has pooh-poohed the increase in version numbers. That’s hardly a legitimate complaint in a world where mobile apps also update silently and effectively, but the transition for Firefox hasn’t been an easy one.
Features and support
Firefox is one of the most progressive major browsers available, an early adopter if not always an innovator. Its features cover the range of browsing essentials, from allowing you to heavily customize your browser while respecting your privacy, to giving developers the tools they need, to supporting the technologies that are driving the future of the Web.
One of the most important features in the modern Firefox is Sync. Sync smoothly synchronizes your add-ons, bookmarks, passwords, preferences, history, and tabs, not only with Firefox on other computers, but also with your Android version of Firefox. It’s easy to set up, and if you’re concerned about privacy, you can change sync to work with your personal server instead of Mozilla’s. Firefox encrypts your data before sending it over an encrypted connection to its servers, where it remains encrypted. Mozilla says that the company would not be able to access it even if somebody there wanted to.
Tabs are a big part of browsing, and Firefox has the best tab management around. Thanks to recent memory-management improvements, you can now comfortably scale from two or three tabs to more than 100 without seeing a major performance hit over time. The aforementioned Panorama lets you group them out of sight until needed, and when you restart Firefox only the last open tab will become active. The others, while visible, won’t load their content until you click on them. Panorama’s groups let you label them which keeps organizational problems to a minimum.
The overall idea is to make it easier to switch from one tab to another, to group or regroup related tabs, and to get a global view of what’s going on with your tabs. It’s potentially a big improvement in browser usage, compared to aiming a mouse at a skinny tab, cycling through a list with Ctrl-Tab keystrokes, or pecking at a drop-down menu to reach the tabs that overflowed off into the deep.
Switch to Tab is a minor feature but incredibly useful. Open a new tab and start typing the name of an already-open tab, and the URL will appear in the drop-down with Switch to Tab beneath it. Select that one, and the new tab closes and you’re whisked to the pre-existing tab. It’s a great trick for cutting down on the amount of time it takes to sift through 45 open tabs, and removes the chance of accidentally having the same tab open twice or more.
You can also drag tabs around to reorder them, pin them as permanent “app tabs” next to the Menu button, or rip them off into their own windows.
Firefox add-ons have long been the brightest feathers in the browser’s cap. While there are other more important browsing developments going on to close observers, add-ons remain important to the vast majority of people. The most popular Firefox add-ons have millions of users. The browser supports modern restartless add-ons, which install without needing to reboot the browser, as well as the legacy add-ons that helped drive its growth.
The add-on manager lets you search for add-ons without going to the external Mozilla Add-on Web site. You can create collections of add-ons to share in the Get Add-ons tab, navigate backward and forward through add-on searches, and as mentioned in the Installation section, it blocks add-ons from installing without your approval.
The Bookmarks and History menus, and Download Manager, leave a bit to be desired. They’re not bad, but it’s clear that they could use some redesigning when compared to the competition. We’d like to see them appear in their own tabs, as they do in Chrome, instead of in separate pop-up windows.
The location bar — or as Mozilla calls it, the Awesome Bar — retains familiar features, such as the options to search your history and bookmarks and to tap into your default search engine to provide you with quick results, without having to use the search box.
The “identity block,” the colored leftmost section of the URL, has been given a refresh to better call out the Web site you’re on. The URL bar itself now changes the text color of the URL you’re on so that the domain is black, for easy identification, while the rest of the URL is gray. This sounds small but is important, since it’s a strong visual cue to help you avoid getting spoofed.
