To delete cookies from one site in Firefox, go to the site, click the shield icon to the left of the address bar, and click Clear cookies and site data. For a site you’re not on, open Settings › Privacy and security, click Clear data for specific sites, search for the site, and click Remove All Shown, then Save Changes.
This guide covers both methods, clearing one site on Firefox for Android, removing all cookies when you need a fresh start, and keeping some sites signed in. The steps follow Mozilla’s guide to clearing cookies and site data in Firefox, updated in 2026. Older versions of Firefox used a padlock icon and a Manage Data button instead.
How to Delete Cookies for the Site You’re On
- Go to the website.
- Click the shield icon on the left side of the address bar.
- Click Clear cookies and site data.
Result: Mozilla says this removes the site’s cookies, site data and temporary cached files and pages. Reload the page, and expect to sign in again.
How to Delete Cookies for Any Single Site
- Click the menu button (three lines) and choose Settings.
- Select Privacy and security on the left and go to the Browsing data section.
- Click Clear data for specific sites. The Manage Cookies and Site Data window opens.
- Type the site’s name in Search websites.
- Click Remove All Shown, or select one entry and click Remove Selected.
- Click Save Changes, then click OK to confirm.
Result: Cookies and stored data for that site are gone, and you’ll likely be signed out of it. Cookies for every other site stay put. Clearing one site this way is also what to try when Firefox says a page is not redirecting properly, as explained in our guide on how to configure redirects in Firefox. If the same site also keeps asking for your location or camera, see how to stop websites from asking for your location in Firefox.
Mozilla also notes that developers can remove individual cookies with the Storage Inspector in Web Developer Tools (Ctrl + Shift + I, then Storage).
How to Clear Cookies for One Site on Firefox for Android
- Go to the website.
- Tap the shield icon in the address bar.
- Tap Clear cookies and site data, then tap Clear to confirm.
- Reload the website.
Result: Mozilla’s Android guide says this clears data for that domain without signing you out of other sites, though it may sign you out of that site and empty its shopping cart.
Other Ways to Clear Cookies in Firefox
Clear all cookies, site data and cache
- Open Settings › Privacy and security.
- In Cookies and Site Data, click Clear browsing data.
- Set When to Everything or a shorter time.
- Make sure Cookies and site data and Temporary cached files and pages are checked, then click Clear.
Clear only cookies and keep everything else
Click the menu button, then History › Clear Recent History. Set When to Everything, check only Cookies and site data, and click Clear.
Clear cookies automatically
A setting in Privacy and security deletes cookies and site data when Firefox closes, with a Manage Exceptions button for sites you want to stay signed in to, such as your email.
When to Clear Cookies for One Site
- A site won’t load properly or keeps showing an old version.
- You’re stuck in a sign-in loop or can’t switch accounts.
- You want a site to forget your preferences without signing out of everything else.
Frequently Asked Questions
Will clearing one site’s cookies delete my saved password?
No. Saved passwords are stored separately in Firefox. You’ll be signed out, but Firefox can fill in your saved login again.
Does this clear the cache for that site too?
The shield icon method does. Mozilla says it removes cookies, site data and temporary cached files and pages for the current site.
