Welcome to the openSUSE Forums! Firefox on Tumbleweed “works well” out of the box, but decoding some formats is restricted for legal / patent reasons, see Restricted Formats.
To play those formats you may have to install proprietary codecs from third party repositories.
I agree for AI, it’s risky… Although that from time to time they do help a lot. GROK saved me several time. With openSUSE, using GROK, I was able to make my Canon MultiFunction printer
I love X and their community notes… Been using it a lot since 2019 and for now it’s one of the best source of info I would recommend on the net. For Linux and computing, I prefer Reddit and forums.
I posted a GROK link… Yes we see x.com but it’s a GROK link. I use GROK through my x account so that is may be why you though it was not a GROK link
