Browser suddenly slow, complains 'storage almost full', or web apps load half their assets.
A corrupt or overgrown browser cache causes weird load errors without obvious symptoms. Clearing it is the first nudge before digging deeper.
Try this first
- 1Open chrome://settings/clearBrowserData or edge://settings/clearBrowserData and pick 'cached images and files' across all time. Skip passwords and cookies, those force everyone to re-login.
- 2On Mac with Safari: enable the Develop menu via Settings, Advanced, Show features for web developers, then Develop, Empty Caches.
- 3Retry the web app. Still broken? Try a private window, which bypasses cache and service workers. If that fixes it, a service worker is stuck on an old version.
- 4Force-update the service worker: DevTools, Application tab, Service Workers, click Unregister, then hard reload with Ctrl+Shift+R.
- 5For one stubborn site: chrome://settings/content/all, find the site, click Remove. That drops cache, cookies, IndexedDB for that origin only.
- 6Set an internal habit: clearing cache belongs in the user-level troubleshooting checklist before calling IT. Saves tickets.
When to bring us in
If the browser remains slow or crashes after a clean cache, the cause is an extension or a corrupt profile. Create a new profile to confirm and escalate with the exact error.
