1) What is cache?
Browsers and apps store some files locally to load faster. This storage is called cache. Over time, old files can cause issues; clearing the cache often fixes them.
2) When should I clear it?
- The site was updated but you still see the old version
- You’re having sign-in issues or unexpected errors
- The browser is noticeably slow
- You want to remove local data for privacy
Note: After clearing, you may need to sign in to some sites again.
3) Quick fixes (very short)
- Hard Refresh — Windows/Linux: Ctrl + F5 · macOS: Cmd + Shift + R
- Reset a single site — From the lock/settings icon in the address bar, clear that site’s data.
4) Clear cache in your browser
Google Chrome / Microsoft Edge (Desktop)
- Open History → Clear browsing data (shortcut: Ctrl + Shift + Del / Cmd + Shift + Delete).
- Time range: “Last 7 days” or “All time”.
- Select Cached images and files (and Cookies if needed).
- Click Clear data. If necessary, restart the browser.
Mozilla Firefox (Desktop)
- Go to Settings → Privacy & Security → Cookies and Site Data.
- Click Clear Data… and check Cached Web Content.
- Click Clear, then restart the browser.
Safari (macOS)
- Option A — Clear History (broader): Safari → Clear History… → choose a range (e.g., all history) → Clear History.
- Option B — Empty Caches (cache only):
- Open Safari → Settings (or Preferences) → Advanced and enable Show Develop menu in menu bar.
- Then go to Develop → Empty Caches (shortcut: Option + Cmd + E).
