Troubleshooting Website Errors by Deleting Browser History
Your browser history is a list of every page you've visited online and the time you were there. A browser can and will hold your history indefinitely. Although cache memory is designed to speed up the performance of many programs it can also cause various computing errors too. Clearing your browser cache is a great way to troubleshoot any website issues you may be having.
Any of these options takes you to the dialog box to delete not only the history of your browsing, but also your download history (it won't delete the actual downloaded files), all your cookies, cached images and files (which help load pages faster when you revisit), saved passwords and more.
Go to the three-dot menu () at the upper-right of Chrome to select Settings > Advanced > Privacy and security > Clear browsing data
History > History > Clear browsing data or More tools > Clear browsing data.
Type "chrome://settings/clearBrowserData" in the omnibar without the quotation marks.
Click Clear History in the History menu. Then in the pop-up, pick a timeframe for how far back you want to erase. This is doing a lot more than deleting the browser history, however—it also takes out your cookies and data cache.
You can instead click History > Show History to get a pop-up displaying every site you've visited, then take out sites individually, without losing the cookies and cache. Zap cookies by going into Preferences > Privacy; delete your cache by going to the Develop menu and picking Empty Caches. If you don't have a Develop menu in Safari, go to Preferences > Advanced and check Show Develop Menu in Menu Bar at bottom.
In the latest version of Firefox go to the hamburger menu () and section Options > Privacy & Security. You're instantly in the Content Blocking section; scroll down to get to History. Set Firefox to remember, to never remember, or get some custom settings like remember history, but not cookies. This section also has a Clear History button. Click it to pick a time range to clear (1, 2, 4, or 24 hours—or everything), and what data to dump (history, logins, forms/search, cookies, and cache).
