Starting with Firefox version 49, Firefox requires Mac OS X 10.9 (Mavericks) or higher. Visit this Apple Support page to find your Mac OS version.

If you're using an outdated version of Firefox on Mac OS X 10.8 (Mountain Lion) or earlier, the only way you can update Firefox to a secure version is to upgrade your Mac OS to a version that Apple supports. Visit this Apple Support page to learn more about upgrading your Mac.

While insecure versions of Firefox will continue to work on OS X 10.8 and earlier, using an up-to-date version of Firefox on a supported version of Mac OS will provide you with the best and safest user experience.

Mozilla Firefox was created by Blake Ross and had additional input by Dave Hyatt. The search engine has become incredibly popular and this is due to the high level of input from Blake Ross, who is a software engineer from America. He has now had nominations from Wired magazine for their top rave award and has also worked with Facebook on several projects.

Blake began getting interested in computers from a very early age and would play games such as SimCity, which would help him develop his ideas about computers and video games in general. He also discovered a version of Netscape when it was in its open source and started contributing software to this platform. After having problems with the platform that he was using, Blake began designing his own and started working for America online, which had purchased Netscape only recently. Ross then went on to inrole at the Stanford university after working as an intern at the Netscape communications corporation. It was whilst working for Netscape that Ross quickly began feeling unsatisfied with the web browsers that were available at the time and it was then that he began thinking about ways in which to create the best web browser possible.

• Firefox warns you when a login form is not secure and your information could be stolen. Refresh Firefox - reset add-ons and settings A Refresh can fix many issues by restoring Firefox to its default state while saving essential information like bookmarks and passwords.
• Each of those programs are available as free downloads. Other PDF readers may also work, however, we do know that the PDF reader native to the Firefox web browser does NOT allow data input. If you use a 'Mac' computer, we strongly suggest that you use the free Adobe Acrobat Reader for Mac in lieu of the PDF reader built-in to the system.

Ross and his partner Hyatt began thinking about a computer browser that would be simple but effective and would also have the ability of gaining a wide amount of attention. The Mozilla Firefox project was released as open source and it began to gain an amount of momentum after this released. Firefox was released to the public in 2004 and Ross was only 19 at the time. However, the web browser quickly gained a lot of attention and received over 100 million downloads in the year that it was released. It is now one of the most popular web browsers that is currently available and is used by many people around the world.

Comparison

It is 2016 and the battle for the best web browser has taken on a new level, with two of the most popular platforms (Mozilla Firefox and Safari) going head to head in the search for the most efficient tool for web surfing. There are many excellent mac web browsers available, and most people prefer installing several to allow them to switch among them as desired. Regardless of this, many people find themselves relying primarily on a single browser for their online activities.
Both Mozilla Firefox and Safari are superb all round options, and they are very efficient as a default
browser. With each release, their developers strive to improve these tools and keep them on the forefront of new web expectations, polish user interfaces, enhance privacy, fix security holes, and improve performance. However, there are certain instances that may warrant one of these browsers a particularly better choice over the other.

Where safari excels

Writing in web-forms

Text area controls in Safari are resizable – simply adjust the handle at the lower right corner in the field.
This comes in handy especially when writing text, leaving comments, and writing blog entries on webpage forms.

Viewing a PDF

The built in PDF support in Safari allows you to view online PDF files right in the window of your browser without having to launch another program (like Apple’s Preview). Mozilla has a free extension as well, known as firefox mac PDF, which allows inline PDF viewing, but without as much elegance.

Full text history searches

Through the direction: History > Show top sites, you can be able to see the top sites view in Safari, with a field at the lower right corner allowing you to search for words that showed up on web pages you recently viewed – whether the pages are open or not. Firefox does not have this ability, although the free Google Desktop allows for a roughly similar capability.
Displaying less popular graphics Safari allows you to view graphics in JPEG 200 or TIIFF formats, both of which are not recognized by Firefox. In Mozilla, you will have to download the file first, and then open it in a separate compatible program, such as Preview.

Where Firefox excels

Regardless of the strengths mentioned above in Safari, Mozilla Firefox tends to stand out in certain
instances, such as:

Using Google Toolbar

This is a free extension that incorporates a long list of user configurable features in the browser, for
instance easy access to Google Gadgets, which allow you to display all kinds of dynamic content,
reminiscent of Dashboard widgets.

Per domain filtering

While safari does permit you to block cookies, pop-up windows, and other features associated with your privacy, they do so as an all or nothing option. Firefox, on the other hand, gives you control over several privacy settings with each domain, allowing a much more diverse browsing experience.

Displaying mathematical equations

Gecko-based browsers (such as Firefox) allow you to view inline mathematical equations developed using MathML standard (of W3C), while WebKit-based browsers such as Safari can only display linear strings of characters.

Tests rendering random websites (firefox vs safari)

A recent test involving Google Maps and Gmail alone revealed that Safari was slower than Firefox on windows. However, two websites are not enough to represent the overall user experience. This problem was fixed by choosing the top 16 English language websites, based on Alexa traffic ratings. As a result, various site designs were tested, from sophisticated DHTML designs to simple static pages. The websites included in the test were:

msn.com
youtube.com
myspace.com
wikipedia.org
hi5.com
blogger.com
microsoft.com
fotolog.net
yahoo.com
google.com
live.com
orkut.com
facebook.com
rapidshare.com
medaupload.com
valentinesgiftsforhim.com.au
friendster.com

These websites were hosted on a local web server, and then both the cached and initial measurements were taken. It was quickly discovered that there was no general winner when it came to the fastest browser. One browser would perform immaculately on one site, while another would take precedence on a different website.
An average of the load times was taken to give a general picture of performance across various websites. Safari was found to be the fastest.

Bottom line

Firefox 45 Download Mac

The length to which Apple’s claims of being the fastest web browser depends on whether you’d like to hold them to the general notion that there is a significant performance edge for Safari, or to the precise numbers. While Safari’s superior performance was confirmed when testing initial webpage load time, the results were inconclusive when it came to loading webpages from cache. The exact browser performance you would experience still depends on the specific website you are visiting.

We will warn you though that after using Mozilla Firefox, you probably wont go back to using anything else.
