Important information and instructions for various configurations and troubleshooting: Linux Mint 22 'Wilma' - Release Notes
Yes, Hardware Acceleration was going to be my next suggestion as well.
Ok, I wasn’t sure if you were using the Firefox Sync features or if you were restoring any of your backed up files pre/post reinstallation, which is why I brought it up again.
Back in the Fall of 2023, I was trying some things to mitigate the infamous YouTube ad-blocker restrictions. Prior to that, I had been using the "Enhancer for YouTube" extension, but later disabled it via "uBlock Origin's" recommended workaround for the ad-blocker restrictions.
I was also testing some things with "NoScript", but found it caused some websites to not load. It's now disabled as well.
Luckily, "uBlock Origin" seems to have solved the problem in an update I received in December, I think.
If you've been doing anything like what I just described, try disabling or uninstalling every extension except "uBlock Origin" and make sure you have the latest version. If that doesn't work, try restoring default settings or disabling/uninstalling uBlock Origin and go from there.
Otherwise, I suspect you might have a bad cache, but it wouldn't hurt to go through this list from top to bottom just to be sure you don't miss something. The article is from 2021, so if the details don't align with your current version of Firefox, etc, just look up how to do the same thing it recommends, only with updated instructions. https://techwiser.com/fix-youtube-not-working-firefox/

Any static red or yellow patterns will cause significant burn in. I have Netflix and YouTube logos as well as their progress bars burned into my 2018 LG from their “smart” TV apps. It took a couple of years to be noticeable, but once it’s there, you always see it.
Picture this: You're a little hungrier than usual. You order four Taco Supremes and one Nachos BellGrande. No combo. No drink. Just main course stuff. This is what you can expect to pay in my neck of the woods, Southern California. And mind you, these portion sizes have been reduced by as much as 40% since 2020. It's not at all unfeasible to understand how one could easily blow $28 feeding one individual after a particularly taxing day.
Let’s say I’m feeling a little more famished than usual, and mind you, these portion sizes are reduced by about 60% on average from what they were prior to 2020. Anyway, I’ve been known to order something like this:

Downvoting because of the paywall. The (perhaps misleading) headline makes it seem like thousands of Ukrainians are fleeing Ukraine to avoid dying for Ukraine’s sovereignty, but this could just as easily be about Russians fleeing Russia to avoid a dying for the Russian elites’ agenda.
Indeed, there was; a sun bear. Here’s a couple clips from that story:
…and here’s another, more-convincing clip from 7 years ago:
They can stand on their hind legs and even walk bipedally. When they stand, it completely changes their body shape; making them look more sapien with large upper torsos.

A new report details how a PR firm paid off critics to post positive reviews of 2018 drama Ophelia on Rotten Tomatoes, prompting scrutiny over the reviews aggregator.
If you've ever dabbled with the synthwave subgenres of outrun (AKA: retrowave, new retrowave, & futuresynth) then you're probably familiar with the Finnish group known as Nightstop. Albums of theirs like “Streetwalker” and the single, “Drive by Stalking” have been staples in the subgenre(s) for years.
Well, I’m here to tell you that their new album is very different from their previous works. It’s a surprisingly magnificent evolution and easily a cyberpunk masterpiece!
Here’s the description from their website (cleaned up for English):
“DEAD GIRLS DON’T DANCE” (2023) is a more-sinister and dangerous dark electro than our previous Streetwalker, synthwave-style releases. The album is inspired by the ultraviolent “Berserk” manga and anime classics like “Akira” and “Cyber City Oedo 808”. It’s a love letter to 80s and 90s Japanese cyberpunk pop culture with a pinch of western imagination. The atmosphere revolves around themes of despair, trust, and betrayal in a Blade-Runner-style dystopia with blade-wielding androids mixed with occult demons and devils.
