Mozilla Firefox is a free, open-source web browser known for being fast, private, and secure. Like other internet browsers, Firefox collects cookies from websites to help remember your individual site preferences. Cookies also keep you logged in to certain websites, which saves time.
If you find yourself logged out of frequently used websites, or websites continually forget your settings, Firefox cookies may have been disabled. Here's how to enable cookies in Firefox and get back this customized functionality.
These instructions apply to the Firefox web browser on iOS and Android devices, as well as macOS and Windows systems.TimeStopper / Moment
What Happens When I Allow Cookies in Firefox?
When you enable cookies, Firefox will automatically collect cookies as you browse the web. This happens in the background and won't interfere with your internet browsing experience.
Cookies are used to keep you logged into a website, so you don't have to sign in every time you visit. Cookies also help websites remember your personal preferences, such as a color theme or which widgets you want to be displayed on a page.
How to Turn on Cookies in Firefox on iOS
If you're using an iOs device such as an iPhone or iPad, enabling cookies in Firefox is a quick and easy adjustment in settings.
Open the Firefox app on your iPhone, iPad, or iPod touch, then tap the three horizontal lines (Menu) in the lower-right corner of the screen.
Tap Data Management.
On the Data Management screen, if the switch next to Cookies is blue, this means cookies are enabled in your Mozilla Firefox app. If you ever want to disable cookies in Firefox, toggle off this switch.
Most internet browsers, including Mozilla Firefox, will have cookies enabled by default, so you likely won't have to enable them unless you or someone else has turned them off.
How to Enable Cookies in Firefox on Android
Enabling Firefox cookies on an Android device is a similar process to iPhones and iPads.
Open the Firefox app on your Android smartphone or tablet and tap the three dots (Menu) in the upper-right corner of the screen.
From this menu, tap Settings > Clear private data.
Despite its name, this option won't clear data and will instead take you to another settings screen.
On the next screen, make sure the box next to Cookies & active logins is checked. If it isn't, tap the box to place a checkmark and enable cookies.
