Browser Troubleshooting / Cache & Cookies
Browser Cache vs Cookies: What to Clear and When
Quick answer
Clear cached files when a page looks broken or outdated. Clear cookies/site data when login or account state is stuck. Do not clear saved passwords unless you intend to. For one broken site, clear data for that site first instead of wiping the whole browser.
Quick diagnosis
If several of these match what you see, you are in the right guide.
- One website looks broken or outdated
- A login loop keeps returning you to the sign-in page
- A site works in private mode but not normal mode
- You are told to clear cache but do not want to lose passwords
Possible causes
- Stale cached files
- Corrupt or outdated site cookies
- Site data conflict after a website update
- Extension issue being mistaken for cache
What you need
- Your browser settings
What this problem usually means
Cache stores copies of page files. Cookies and site data store sign-in and site state. They solve different problems, and clearing both can create extra work.
Before you start
- Try a private/InPrivate window first.
- Know your passwords before clearing cookies.
- If only downloads fail, use browser downloads failing.
Quick fixes
1. Choose the right thing to clear
- Broken layout or old image: clear cached files.
- Login loop or wrong account state: clear cookies/site data for that site.
- Popups or redirects: check extensions before clearing everything.
- Only one site: clear one site first.
2. Use a private window as a test
If private mode works, cache, cookies, extension settings, or profile data are likely. If private mode fails too, the site or network may be the issue.
Step-by-step troubleshooting
Chrome and Edge
Settings → Privacy and security → Clear browsing data. Keep passwords unchecked. For one site, use site settings or the lock icon to clear only that site's data.
Firefox
Settings → Privacy & Security → Cookies and Site Data. Clear Data lets you choose cached web content and cookies/site data. Use Manage Data for one site.
When clearing does not help
If the same site fails in multiple browsers after clearing only that site, use some websites won't load. If disabling extensions fixes it, use the extension guide.
Cache, cookies, or something else?
Choose an answer. The next question appears below, no account or download required.
Clear site data or disable extensions. Start with the smallest change.
Check website, DNS, network, or account/service outage.
Clear cookies/site data for that site, then sign in again.
How to know the problem is fixed
- The same site works in a normal window.
- You can sign in if login was the issue.
- Saved passwords remain unless you intentionally cleared them.
If the problem continues
Disable extensions, test another browser, then move to site/DNS troubleshooting. Do not keep clearing all browser data after the first clean test.
When this may be hardware failure
Cache and cookies are browser data, not hardware. Hardware is not the likely cause of one site's stale layout or login loop.
Common mistakes to avoid
- Clearing saved passwords accidentally.
- Clearing all cookies for one broken site.
- Ignoring extensions when private mode fixes the page.
Frequently asked questions
Will clearing cache sign me out?
Usually no. Clearing cookies or site data can sign you out.
Should I clear everything monthly?
No. Clear data to solve a specific problem, not as routine maintenance.
