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?
Yes, Mozilla also has Hubs, vpn, Pocket and more
Pocket is one where I wish Firefox Mobile had integration instead of needing a separate app.
