Frequently Asked Questions

To clear Mozilla Firefox cache on your iPhone 16 Pro, open the browser settings, navigate to the privacy or browsing data section, select cached files, and tap clear. Follow our detailed step-by-step guide above for the exact instructions specific to Mozilla Firefox on your iPhone 16 Pro.

Will clearing Mozilla Firefox cache on iPhone 16 Pro delete my passwords?

No. Clearing the cache on your iPhone 16 Pro only removes temporary website files like images and scripts. Your saved passwords in Mozilla Firefox are stored separately and won't be affected. Just make sure you only select 'Cached images and files' and leave 'Passwords' unchecked.

How often should I clear Mozilla Firefox cache on my iPhone 16 Pro?

For most iPhone 16 Pro users, clearing the Mozilla Firefox cache every 2-4 weeks is a good routine. If you browse frequently or notice slow performance, you might want to clear it more often. There's no harm in clearing the cache — it's a safe and routine maintenance step.

Will clearing cache speed up Mozilla Firefox on my iPhone 16 Pro?

Yes, clearing the cache can often improve Mozilla Firefox's speed on your iPhone 16 Pro, especially if the cache has grown large or contains corrupted files. After clearing, the first page loads may be slightly slower as resources are re-downloaded, but overall performance usually improves.

Is it safe to clear Mozilla Firefox cache on iPhone 16 Pro?

Absolutely. Clearing the Mozilla Firefox cache on your iPhone 16 Pro is completely safe. It only removes temporary files — your bookmarks, passwords, browsing history, and personal data remain untouched. It's a routine maintenance task recommended by tech professionals.

Will I be logged out of websites after clearing Mozilla Firefox cache on iPhone 16 Pro?

If you only clear the cache (cached images and files) in Mozilla Firefox, you will NOT be logged out. However, if you also clear cookies and site data, you will be logged out of most websites. When clearing, only check the cache option to stay logged in.

What does Mozilla Firefox cache on my iPhone 16 Pro actually store?

The Mozilla Firefox cache on your iPhone 16 Pro stores temporary copies of website resources — images, CSS stylesheets, JavaScript files, fonts, and other web content. This allows Mozilla Firefox to load previously visited pages faster by using local copies instead of downloading everything again.

How much storage does Mozilla Firefox cache use on iPhone 16 Pro?

The Mozilla Firefox cache size on your iPhone 16 Pro varies based on your browsing habits, but it typically ranges from a few hundred megabytes to several gigabytes. Heavy browsing and visiting media-rich sites increases cache size. Clearing the cache is an easy way to reclaim storage space.

Can I clear Mozilla Firefox cache for just one website on iPhone 16 Pro?

In some cases, yes. On desktop versions of Mozilla Firefox, you can clear cache for specific sites through developer tools or site settings. On mobile, the options may be more limited. For the most reliable fix, clearing the entire Mozilla Firefox cache is recommended.

What's the difference between cache and cookies in Mozilla Firefox on iPhone 16 Pro?

On your iPhone 16 Pro, the Mozilla Firefox cache stores website files (images, scripts) for faster loading, while cookies store data like login sessions and preferences. Clearing cache helps fix display issues; clearing cookies logs you out of sites. These can be cleared independently.
