How to Clear the Firefox Cache on Android and iPhone

On Android, Firefox clears its cache from the three-dot menu: Settings → Delete browsing data, tick Cached images and files, tap Delete browsing data. On iPhone the path is the menu → Settings → Data Management, where each type of data has its own switch: leave only Cache on and tap Clear Private Data — Mozilla's help page warns the action cannot be undone, so check the switches first. Neither route touches your bookmarks, and neither signs you out unless cookies are included. Below are the exact taps for both platforms, from Mozilla's support articles, the way to clear a single site instead of everything, and the switch that empties the cache every time you quit.
Before you start
Know what the cache is and what it is not. Mozilla's Firefox for iOS help page defines it as "parts of web pages that are stored in the browser to make them load faster the next time you visit" — images, scripts, page fragments. It is separate from browsing history (the list of addresses you visited), from cookies (the files that keep you signed in and remember site preferences), and from offline website data (files a site stores so it works without a connection). Clearing the cache alone loses nothing you would notice except speed on the next visit.
Know which app you have. This guide is for Firefox, Mozilla's full browser, not Firefox Focus. The steps come from Mozilla's support articles for Firefox for Android and Firefox for iOS, and the menus differ between the two platforms: Android uses checkboxes on one screen, iPhone uses switches that stay set until you change them.
Know that this is usually the wrong first move for a "storage full" warning. Firefox's install is 254 MB on Android and 382 MB on iPhone before any cache; clearing the cache recovers the cached pages only, which on most phones is tens of megabytes, not gigabytes.
Step 1. Clear the cache on Android
Mozilla's Android article gives six taps:
- Tap the three-dot menu button.
- Tap Settings.
- In the Privacy and security section, tap Delete browsing data.
- Select the types of data to delete. The list is: Open Tabs, Browsing history, Cookies and site data, Cached images and files, Site permissions, Downloads. For the cache alone, tick only Cached images and files and untick the rest.
- Tap Delete browsing data.
That is the whole procedure. Leaving Cookies and site data unticked keeps you signed in everywhere; leaving Open Tabs unticked keeps the tabs you have open. If the phone was slow on a particular site, ticking Cookies and site data as well clears that site's stored state, at the cost of signing in again.
Step 2. Clear the cache on iPhone or iPad
Mozilla's iOS article lists what Clear Private Data can remove — browsing history, cache, cookies, offline website data, tracking-protection exceptions — and the Data Management screen shows each of them with a switch. Only the types switched on are cleared. The route:
- Tap the menu button at the bottom of the screen (top right on an iPad).
- Tap Settings.
- Under Privacy, tap Data Management.
- Check the switches: leave Cache on and turn the others off if you want the cache alone.
- At the bottom of the list, tap Clear Private Data.
Mozilla's caution on that page is worth quoting exactly: "This action will clear all of your private data and cannot be undone." With Cookies switched on, sign-ins go with it, so look at the switches before tapping. Firefox's own saved logins are managed from the same screen and are not deleted unless you choose them.
If you would rather clear one site than one category, use the per-site route in Step 3.
Step 3. Clear one site instead of everything
Both platforms can target a single site, which is the better fix when one page misbehaves.
iPhone: menu → Settings → Data Management → Website Data → tap the site, or Show More to find it → Clear Items at the bottom of the list. This removes that site's stored data — cache, cookies and offline files — and leaves every other site alone.
Android: Firefox for Android's Delete browsing data screen works on categories rather than sites, but Cookies and site data can be managed per site from Settings → Site permissions, and the history list lets you delete a single entry with the ✕ beside it, or several by long-pressing one entry, tapping the others, then the three-dot menu → Delete. That clears the addresses, not the cached files; for the files, Step 1 with only Cached images and files ticked is the smallest action available.
Step 4. Make Firefox clear it on every quit (Android)
If you would rather not repeat Step 1, Firefox for Android has a switch for it. Mozilla's article:
- Three-dot menu → Settings → Delete browsing data on quit in the Privacy and security section.
- Slide the switch on.
- Choose the types of data to delete on exit — the same six categories, so tick Cached images and files and leave the rest as you prefer.
Once the switch is on, a Quit option appears in the three-dot menu. Closing the app from the app switcher does not trigger it; only Quit does. Firefox for iOS has no equivalent setting — Mozilla's support forum has carried that request for years — so on iPhone the cache is cleared by hand.
Android also offers a route that bypasses Firefox entirely: the phone's Settings → Apps → Firefox → Storage & cache → Clear cache. That empties the app's cache directory at the system level without touching cookies, sign-ins or bookmarks, and the space is reclaimed immediately.
If it does not work
The storage number on the phone did not change. The cache is a small part of what Firefox occupies; the app itself is 254 to 382 MB. If storage is the problem, the fix is elsewhere on the phone, not in the browser.
The site still shows the old page. You cleared the cache but not the site's cookies or offline data. Clear that site's data (Step 3 on iPhone; Cookies and site data in Step 1 on Android), then reload.
You were signed out of everything. Cookies were included. On Android, next time untick Cookies and site data; on iPhone, the Cookies switch on the Data Management screen was on — switch it off before Clear Private Data, or use Website Data for one site instead.
The Quit option is missing. Delete browsing data on quit is off. It only appears in the menu once the switch is on.
You cleared history but the cache is still there. The history trash icon on iPhone and the ✕ in the Android history list delete addresses only. The cache lives under Data Management on iPhone and under Delete browsing data on Android.
Bottom line
Android: three-dot menu → Settings → Delete browsing data → tick Cached images and files only → Delete. iPhone: menu → Settings → Data Management → leave only the Cache switch on → Clear Private Data, which cannot be undone — or Website Data → the site → Clear Items to clear one site cleanly. Bookmarks survive both; sign-ins survive only if cookies are left alone. And if you are doing this to free space, expect megabytes, not gigabytes.
