You might have malware on your computer. Here is an old post I made with some things you can do to check and fix if needed your computer.
If you have a Windows computer, try the following one at a time and see if it helps.
For a very good free tool to clean up your computer, download CCleaner from Piriform. Run it before and after each browser session. CCleaner by defaults will remove some useful cookies that are used to store some internet site preferences you might have. You might get prompted again when you go to an internet site. No problems with eBay.
One change you should make to the default settings in CCleaner is to delete information in the past 24 hours. By default CCleaner does not delete this. If you are having issues, you need to clean all of the cookies and cache and especially the current ones since they might have the problem.
You can download the free version of CCleaner here

Choose the free version on the left, not the trial version on the right.
I have run CCleaner for 10+ years now and have had very few issues with browsing eBay and the Internet. Computer has been responsive and fast.
Another free tool you might want to have is AdBlockPlus. It is a browser addon that blocks most annoying ads on eBay and other sites. This will speed up your browsing since eBay is full of third party moving ads today.

Just download and install it. It updates automatically so you never do anything to maintain it.
Next, you might want to download and install a free malware program to check you computer for stuff that might have been installed on your computer. This program is one of the best for finding malware. A few months ago some eBay members have posted that issues they were having with their computer with eBay were fixed by running this program.

Download the free version on the right. Run this program once and then every month or two as needed.
Last, I would recommend having more than one Internet browser installed on your computer. I use FireFox browser as my default browser and it has worked well over the years. I also have Internet Explorer installed and up to date but Internet Explorer usually has more issues with eBay and other sites so I rarely use it. I have Google Chrome browser installed as a backup browser but it has had more issues with eBay and PayPal over the years compared to FireFox. These browsers are all officially supported by eBay. I also have Opera browser installed which I find is a good Internet browser but not officially supported by eBay.
Do the above one at a time and check if they fix your issue. Still run all of them but try to find which fixes the issue. Using all of the above regularly should make your computer run faster and better than before
I hope this helps. Post back what you did and how it went so that other readers know if it helped.
