Why is Yahoo Mail so Slow on Chrome or Another Browser?

Since Yahoo Mail is a web-based application, if you’re using it on your computer then you’re likely accessing it via web browser. So, it’s a good idea to try Yahoo Mail in a different browser as a first step which can help identify where the problem lies.

If the issue appears to be with Google Chrome, the below solutions apply to Chrome since it is the most common browser used to access Yahoo Mail. However, you can follow similar steps in whichever browser you use.

Cache and Cookies

Stale cache and cookies can slow down most any browser. So, clearing these can improve browser performance which in turn, can speed up Yahoo Mail.

💡 Solution: Open the menu (three dots) on the top right and select Settings. Go to Privacy and securityDelete browsing data and use the tabs to select and delete history, cookies and data, and/or cached items. Note that you may need to log in to frequently visited websites after clearing this data.

JavaScript Disabled

Why is Yahoo Mail so Slow on Mac or Windows?

If you’re still having trouble with Yahoo Mail after going through the above web browser solutions or Yahoo Mail is slow regardless of which browser you use, there are a few computer-related things you can check.

VPN, Firewall, or Security Software

VPNs, firewalls, and security software can interfere with Yahoo Mail by masking IP addresses and blocking certain websites.

💡 Solution: You can temporarily disable the service or software and see if it speeds up Yahoo Mail. If applicable, you can adjust the settings for the service or software to add Yahoo Mail as an exception.

Application Interference

Other software or programs running on your computer can cause Yahoo Mail to slow down such as applications using significant CPU or memory.

💡 Solution: On Mac, go to ApplicationsUtilities and open Activity Monitor. On Windows, right-click the Taskbar and select Task Manager. Both tools show which processes are running and the amount of system resources they use. You can also stop a current process.

Email App Sync Settings

If you’re using Yahoo Mail with a separate email app like Gmail on Android or Mail on iPhone, you can experience problems with it syncing properly to display the latest messages.
