How to Clear Browser Cache to Improve Internet Speed in 2021

Last Updated: February 5, 2021

The web browser cache within your browser is set by default to copy web data and elements from every web page you visit. This actually speeds up subsequent visits to the website as your web browser will be able to load the web page elements directly from your computer.

However, this data can accumulate and create such a long list of data files that it may contradictorily slow down your web browser. This may cause Internet errors that can crash or freeze-up your web browser.

WARNING: Deleting the Internet Cache (Temporary Internet Files and Browsing History) may remove saved passwords, logins, and other saved web data. To learn more (much more) on the browser cache, see Wikipedia's computing cache article.

We also show you how to change the disk space used to set the cache size and other settings further down the page.

Clear Cache for All Web Browsers

You may want to clear the Internet cache for privacy and security issues, or to solve a browser crash or freeze at a website due to old incompatible data files that need to be changed for the web site to display properly.

For security and privacy reasons alone, it may be a good idea to clear out the cache every once in a while. After all, the Browser Cache is a prime target for malicious web code that may try to initiate within the Temporary Internet Files folder.

The cache may include web videos, pictures, emails, web page text, and even personal information that can be a security risk (ID Theft) if left lingering on a PC.

Unfortunately, clearing your Web Browser cache can actually slow your Internet speed since all of the saved web site files will have to be downloaded again instead of using the browser cache. A much more effective solution is to use an Internet optimizer download to fully optimize your hidden Internet settings. Using advanced network optimization technology, the cache is used much more effeciently to boost your web page load times, accelerate your downloading and surfing speed, while improving video streaming as well.

WARNING: Deleting the Internet Cache within any browser may remove saved passwords, logins, and other saved web data. Described below are quick delete methods, see your browser's Help section for more detailed control of your cache.

Clear Google Chrome Cache:

Click the Wrench icon at the top of the Google Chrome browser. Hover your mouse down to Tools and select Clear Browsing Data. You may also open the pane by pressing the Ctrl+Shift+Del keys together.

Next, simply select the items you wish to delete and make a selection for the time period. Then click the Clear browsing data button and you're finished.

Clear Microsoft Edge Cache:

Click the Hub icon at the top right, then click the History icon. Find and click on the link that says, "Clear all history".

Next, you are given a number of checkboxes of items you would like to clear including the Internet cache - titled "Cached data and files". There's also a "Show more" link that includes a few more options to clear.

After choosing your items to clear, simply click the "Clear" button and you will be given a message stating it is clearing the data. After a few seconds (or longer if there's a lot of data) the "All Clear" message will appear and you're done.

What if you don't use Microsoft Edge? You may still want to clear the Microsoft Edge cache because those browsers are installed and embedded into the Windows operating system and there may be unneeded web data present.

Clear Mozilla Firefox Cache:

To clear the cache in Firefox 3, I clicked on Tools, then selected Options. Next, click on the Advanced tab (top right) and then click the Network tab. You'll see the amount of Offline Storage is set for your cache.

To the right is the Clear Now button. Clicking it will of course clear the Firefox Cache. You can also quickly Clear Recent History by pressing the Ctrl+Shift+Del keys together. Then choose the Details and check each one you would like cleared. Then click the Clear Now button.

Clear Apple Safari Cache:

Press the Ctrl+Alt+E keys together to open up a box displaying, Are you sure you want to empty the cache? Clicking the Empty button will clear the Safari Cache.

An Empty Cache option is listed within the Menu bar under the Edit tab, but it essentially leads to the same place. To get more control of the cache files in Safari, click the gear icon at the top right and select preferences, or press Ctrl+, (that's Control + Comma) on your keyboard.

Under the General tab, you can control history time period. The AutoFill tab controls usernames, passwords, and other forms. Finally, the Security tab gives you access to the Safari Cookie settings.

Clear Opera Cache:

Depending on whether the Menu bar is shown or not, there are 2 ways to delete the Opera cache.

(1) Click the red Menu tab at the top left of the Opera browser and hover down to Settings and then select Delete Private Data.

(2) If the Menu Bar is active, click on Tools and select Delete Private Data.

After opening the box with one of the above methods, click on Detailed Options and select the items you wish to remove from your computer. You can also Manage Cookies and Manage Passwords from here.

If you want to delete the items you selected, simply click on the Delete button. Of course, more detailed information is available by clicking on the Help button which will take you to the Help section of Opera's web site.


I hope you learned a few things about the Internet cache and its' affect on how your browser displays web pages. By fidgeting with the cache settings of all the different web browsers, I certainly learned a lot. Thanks for reading.
