Does this happen in all browsers you try (Internet Explorer, Edge if you have Windows 10, Firefox, Chrome, the last 2 are free to download and install), or in only one?
If it's in one browser only, reset that to default settings. The way to do that is different for each browser but since you didn't tell what browser you use, I can't be more specific. Google it or tell more.
https://www.google.com/search?q=%22A+web+page+is+slowing+down+your+browser makes me think you're using Firefox. In that case, before doing anything else, read through the hits. It could very well be that there are better solutions than the general advice I gave above,.
I keep getting a yellow box at the top of my web pages stating "A web page is slowing down your browser". I have two options in small boxes. I can click Stop or or Wait. Please help me fix this. It makes my laptop very slow. Thanks.
