My wife installed an addon to be able to post Instagram posts from her laptop, and then suddenly clicking on google search results would sometimes, but not always hijack and redirect to bing, and then click on one of the ads. But it was clever because it only happened sometimes, and if she retried it it didn't happen, so whenever she would try to show me, it didn't happen. I just removed all her addons and the problem went way, so not sure which one it was.
