Clear the Cache From the Firefox Mobile App

Clearing the cache in the Firefox mobile app is similar to the desktop version. The option to delete the Firefox cache is in the settings, and you can choose what type of data to erase in addition to the cache, like browsing history and cookies. In Firefox for Mac, open the Firefox menu, then choose Preferences. Or, on a Windows or Mac computer, enter about:preferences in a new tab or window.​ If you want to clear other stored data, like the browsing history, select the appropriate check boxes. These are cleared with the cache in the next step.​ If the internet cache is large, Firefox may hang while it finishes removing the files. Be patient—it eventually finishes the job.

What Is the Firefox Cache?

The Firefox cache contains locally saved copies of web pages you visited recently. This way, the next time you visit a page, Firefox loads it from the saved copy, which is faster than loading it again from the internet. Clearing the cache in Firefox doesn’t need to be done every day, but it can solve or prevent certain problems. If the cache doesn’t update when Firefox sees a change on the website or the cached files are corrupted, it can cause web pages to look and act strangely.

Tips for Clearing the Cache in Firefox

You can save time and clear the cache as specifically as you want with some advanced methods and shortcuts.

Some older versions of Firefox have similar processes for clearing the cache, but you should keep Firefox updated to the latest version. Use the Ctrl+Shift+Delete combination on the keyboard to immediately go to Step 5 above. If you don’t want to delete all the cache stored by Firefox, choose a different time range at Step 5. Choose either Last Hour, Last Two Hours, Last Four Hours, or Today. In each instance, Firefox clears the cache if the data was created within that time frame. Malware can sometimes make it difficult to remove the cache in Firefox. You might find that even after you instruct Firefox to delete the cached files, they still remain. Scan your computer for malicious files and then start over from Step 1. To view cache information in Firefox, enter about:cache in the address bar. Press and hold the Shift key while refreshing a page in Firefox (and most other web browsers) to request the most current live page and bypass the cached version. This can be accomplished without clearing out the cache as described above.
