Firefox users report high CPU and memory usage in the latest release, caused by browser's on-device AI inferencing for its 'smart tab grouping' feature.

it was enabled for me and I just took it off. I ever enabled it so it must be default to have it on.

If by "enabled" you mean you saw a button "Suggest more of my tabs", then I believe that is present by default, but I believe it only downloads the model when you actually press that button for the first time. At least it did for me.

It's possible that I'm misunderstanding what it does otherwise though. Still, does not appear to have been the cause of this particular issue.

nope. literally says "Use AI to suggest tabs and a name for tab groups" and the slider was activated and I flipped it to off. Never saw a download but when it updates firefox either has to be closed or it restarts.

Rules

While we are not an official Mozilla community, we have adopted the Mozilla Community Participation Guidelines as far as it can be applied to a bin.

Rules

  1. Always be civil and respectful
    Don't be toxic, hostile, or a troll, especially towards Mozilla employees. This includes gratuitous use of profanity.

  2. Don't be a bigot
    No form of bigotry will be tolerated.

  3. Don't post security compromising suggestions
    If you do, include an obvious and clear warning.

  4. Don't post conspiracy theories
    Especially ones about nefarious intentions or funding. If you're concerned: Ask. Please don’t fuel conspiracy thinking here. Don’t try to spread FUD, especially against reliable privacy-enhancing software. Extraordinary claims require extraordinary evidence. Show credible sources.

  5. Don't accuse others of shilling
    Send honest concerns to the moderators and/or admins, and we will investigate.

  6. Do not remove your help posts after they receive replies
    Half the point of asking questions in a public sub is so that everyone can benefit from the answers—which is impossible if you go deleting everything behind yourself once you've gotten yours.
