Will clearing Mozilla Firefox cache on Samsung Galaxy S25 delete my passwords?

How often should I clear Mozilla Firefox cache on my Samsung Galaxy S25?

For most Samsung Galaxy S25 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 Samsung Galaxy S25?

Yes, clearing the cache can often improve Mozilla Firefox's speed on your Samsung Galaxy S25, 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 Samsung Galaxy S25?

Absolutely. Clearing the Mozilla Firefox cache on your Samsung Galaxy S25 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 Samsung Galaxy S25?

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 Samsung Galaxy S25 actually store?

The Mozilla Firefox cache on your Samsung Galaxy S25 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 Samsung Galaxy S25?

The Mozilla Firefox cache size on your Samsung Galaxy S25 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 Samsung Galaxy S25?

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 Samsung Galaxy S25?

On your Samsung Galaxy S25, 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.
