I went here to get rid of that tab preview in Firefox.
I tried the ideas in the post by the moderator.
None worked.
Will this ensure that I never get my Firefox updated to a newer version?
This is a tad bit tempting for the Mozilla team. (Just kidding. 
)
For those who want some humor.
I have had a great day.
This will ensure that you won't get updates at all, not for the rest of yor OS, or even security updates for MATE.
Thanks.
That sounds good.
Don’t try this yet, let someone like Pavlos or Eric comment first, but on my cheat sheet I have a ‘hold command’ that I think will do just that:
echo "firefox hold" | sudo dpkg --set-selections
I used it years ago on iceweasal.
echo "iceweasel hold" | sudo dpkg --set-selections
Also this is not recommended for security reasons!
Thanks for the help.
I accidentally ran the command. Just kidding.
to prevent apt from updating a package, sudo apt-mark hold package-name
to allow updating, sudo apt-mark unhold package-name
Thank you for the referral, Jim, but I don't feel I know enough on that feature to comment, and even less of an expert to even venture an opinion/recommendation.
I will leave that with Pavlos (@pavlos), whom I think is more of an "experimentalist" than I am, and has shown he has much greater depth for many things than I do.
I characterize my knowledge as potentially deep, but in very narrow areas, because I either maintain a surface level knowledge of most topics, or I dig in quite deep for others that raise points that my curiosity and instincts simply will not allow me to walk away with "incomplete" knowledge or puzzling contradictions as perceived from an abstracted level.
I think like some commands they changed over time or get outdated. How long is it since ice weasel was around?
Thanks a lot.
andy@7:~$ sudo apt-mark hold firefox
