As there seems to have been recent confusion about this, just a quick "official" toot to then pin: we haven't and won't support "generative AI" related stuff in LibreWolf. If you see some features like that (like Perplexity search recently, or the link preview feature now) it is solely because it "slipped through". As soon as we become aware of something like this / it gets reported to us, we will remove/disable it ASAP.

@librewolf First: Thanks for all your hard work over the years.

While it’s great to have this social post clarification, it would help a lot going forward too if this ’No AI’ stance was posted somewhere on the website like ‘No Telemetry’ is under Main Features so it is more discoverable. Both Waterfox and Vivaldi have their No AI stances posted on their website blogs:

No AI* Here - A Response to Mozilla's Next Chapter - Waterfox Blog

Mozilla's pivot to AI first browsing raises fundamental questions about what a browser should be.

@sylvie good point. The website / documentation is currently somewhat outdated in a bunch of places, unfortunately, and needs a bit of work. Once that happens though, we'll certainly add it! :)
