How Firefox compares to other browsers

Get all the speed and tools with none of the invasions of privacy. Firefox Browser collects so little data about you, we don’t even require your email address to download. That’s because unlike other browsers, we have no financial stake in following you around the web.

Compare Firefox to:
Blocks third-party tracking cookies by default
Autoplay blocking
Blocks social trackers
OS availability
In-browser screenshot tool
Primary password

We block the ad trackers. You explore the internet faster.

Ads are distracting and make web pages load slower while their trackers watch every move you make online. The Firefox Browser blocks most trackers automatically, so there’s no need to dig into your security settings.

Firefox is for everyone

Available in over 90 languages, and compatible with Windows, Mac and Linux machines, Firefox works no matter what you’re using or where you are. Make sure your operating system is up to date for the best experience.

Put Firefox on all your devices

Take your privacy with you everywhere. Firefox Browsers for iOS and Android have the same strong privacy settings to block trackers from following you around the web, no matter where you are.

Firefox Old Version 3.6 Free Download For Mac

Challenging the status quo since 1998

Firefox was created by Mozilla as a faster, more private alternative to browsers like Internet Explorer, and now Chrome. Today, our mission-driven company and volunteer community continue to put your privacy above all else.

Your privacy comes first

As the internet grows and changes, Firefox continues to focus on your right to privacy — we call it the Personal Data Promise: Take less. Keep it safe. No secrets. Your data, your web activity, your life online is protected with Firefox.

Warning: Firefox now includes downgrade protection to prevent corruption of user profile data. If you install an older version, you'll be prompted to create a new Firefox profile.

If there is a problem with a Firefox version, most people will try to revert Firefox back to the way it was before and downgrade it, but we do not recommend this action. Downgrading Firefox leaves a user more vulnerable to attacks and, on most occasions, doesn't fix the problem that occurred while updating. This article gives you some alternatives to downgrading and links to old versions of Firefox, if you do choose to downgrade.

Table of Contents

Problems with an update are generally not caused by the new version of Firefox, but rather the update process. Installing a previous version will not help in most cases. Instead, see:

Note: Other problems can be solved with the Refresh Firefox feature. It restores Firefox to its default state while saving your essential information.

Ensure all security and security-related software is fully updated. Some security software will need to be upgraded to a new version for each Firefox version update.

Optional software bundled with security software may also need updating. Such software may not be essential for your security, but if outdated, it may interfere with the use of Firefox, or cause Firefox to crash.

If you want to downgrade, you can visit Mozilla's directory of older Firefox versions using the link below. Please note, however, that using older versions of Firefox can be harmful and that we recommend you use the newest version of Firefox.
