Clear web data in web browser

About clearing web data in your browser, when websites are not working as they should.

If you can't sign in to a website or the website isn't working as you expect, you can try clearing the web data in your browser to fix the problem.

Here you find tutorials that show how to clear the browser's cache, cookies and browsing history in different browsers and on different platforms.

Find the name of your web browser

If you are unsure of which version of the web browser you are using, follow these steps:

  1. In your browser, open the menu. The symbol is usually three dots, three dashes or a gear symbol.
  2. Open the "Help" submenu.
  3. You should now see a selection called "About [browser name]"

If you do not see the instructions for your specific version or browser, search the browser's Help menu for "Clear Cache / Clear History".

Note! Restart your browser after clearing it according to one of the reference guides.
