Hi, your caution is warranted. Some people are cashing in on the sudden interest in ChatGPT by encouraging people to install untrustworthy add-ons. And even if the add-ons aren't spying on you, Open AI tells you that it uses your input as part of its development process.
Some features in Firefox have been available for so long that we can't remember life before them, such as searching from the address. But some people still don't even trust searching through the address bar, so there is a hidden preference to disable that. I assume that any AI features offered in the future will be even easier to turn off.
