When you visit the Google’s chatbot bard’s website in Microsoft Bing. A New Button pops up besides the search bar which lets you compare bard results with Bing chat’s. I have no idea why they implemented this, well maybe to show off the their chatbot is better than bard or something?
I’ve been using Firefox for years to access Google services, and have never ever had a single issue. I hope it stays this way, with all this Web Environment Integrity shenanigans they are pushing for at the moment.
