How to clear the browser cache in Firefox

Your internet cache stores a copy of each web page you visit on your PC's hard drive, in order to speed up page loading times on sites you revisit within a day or two. This feature serves its intended purpose, but can cause problems during the design-proofing process, with clients still seeing the previous version of their site despite a new version being live. Sometimes just pressing your browser's 'Refresh' button can clear this problem.

If the browser refresh doesn't work then you will need to manually clear these files.

We suggest that each time you are asked to review a change made to your web site, you clear your internet cache beforehand, to avoid confusion.

1. First navigate away from any page suspected to be cached.

2. Click the Menu button (aka the "hamburger button" - the one with three horizontal lines in the top right hand corner of the browser window) and then choose Settings.

Note: You can also enter about:preferences in the address bar of a new tab or window.

3. Once the Settings window is open, click the Privacy & Security tab on the left.

4. Scroll down slightly until you see the heading Cookies and Site Data, click the button Clear Data.

5. You should next see a pop-up window appear titled Clear Data.

6. In the pop-up window you should see two options, uncheck the Cookies and Site Data option and leave the option for Cached Web Content checked.

Note: If you wish to clear other kinds of stored data, feel free to check the appropriate boxes. They will be cleared along with the cache in the next step.

Tip: Don't see anything to check? Then click the down arrow next to Details. The list of checkable options will appear.

7. Click on the Clear button.

5. When the Clear Data window closes, all of the cached files (saved files) from your browsing activities in Firefox will have been deleted.

Note: If your internet cache is large, Firefox may hang while it finishes removing the files. Please be patient - it will eventually finish the job.

Finally

If the above steps do not fix the problem, it is possible that the files are being cached by a web server in-between your computer and our server. Please call the webteam on 01253 608013 to discuss further steps we can take to temporarily work around the problem.
