No idea what's going on, but if you're paranoid, you can always

rm -rf ~/.cache/mozilla/firefox

to destroy all cached files.  This probably also includes profiles and settings, though, so if you want to save some things, you may need to refine that rm target appropriately.

Dad: I... I... think I'm having a heart attack. C-call me an ambulance, quick!
Son: OK.  Uh... dad, you're an ambulance.

A depressed guy was talking to his therapist.  "I can't deal with my problems anymore!"

The therapist replied, "Have you ever tried becoming a school bus driver?"

"What has that got to do with my problems?"

"Because then all your problems will be behind you!"

Shoot the messenger?  Whoa, slow down, soldier.  I wrote a post explaining why I came to Devuan, which, might I emphasize, did not contain any insults or ad hominem, especially not anything involving you. And your response was, I quote:

I guess I must have missed the memo, is this how people welcome each other in 2024?  Wow, I'm so outdated on what the new norms are on social etiquette.  Is this what they mean by "generation gap"?  Guess I should crawl back to my primitive cave and stay there until I learn how to treat another human being with ad hominem and derision as a way of encouraging their contribution.  It's certainly a novel idea, I must say.  Never thought of it before myself.  I guess I have you to thank for this enlightenment.

Now excuse me while I retire to my cave to muse over the deep significance of this "revelation".

Back in the 90's when the joke that was Windows 95 was still the talk of the kids, I decided to leave that world behind forever.  At the time, Linux was a (very) niche OS that nobody has hardly heard a thing about.  I reviewed the handful of distros that existed back then, and chose Debian for being the most flexible and convenient: I could leverage the package repo without having to compile everything by hand, yet I could customize the OS as I wished, trimming off unnecessary fat and installing only the bare minimum of what I needed, nothing more, nothing less.

Back then, I couldn't care less that nobody among my peers used Linux, or even knew what Linux was (except that one friend who recommended it to me at first).  Whenever I mentioned that I used Linux, I would get incredulous stares and blank looks.  Did I care?  Of course not.  The Debian of the 90's gave me the best balance between convenience and control, and I could finally be free of the tyranny that is the Windows ecosystem.  I didn't care that I had to leave behind a lot of popular software that the kids loved to boast about.  What I cared for is that finally, I had control over my own machine.  And as a then-aspiring programmer, that's all I cared about.  Who cares about the eye-candy that Win'95 offered?  It was a joke that I couldn't care less about.  Linux let me dig under the hood and modify things to my heart's content.  I, the user, was empowered.  That was what mattered.

Sadly, the Debian of 2024 is a very different world.  The hacker mentality of the 90's had long gone. People cared more for winning the approval of the masses than for what truly mattered: the empowerment of the user.  In place of that is the empowerment of the upstream.  Folks like the systemd guys wanted to control everything.  The proprietary mentality has infiltrated what was once an open mentality. (Ironically, it seems that in history, every time the word "open" became part of a project's name, the project became closed and controlled by the few rather than the many.)  In their efforts to please the masses, they are ready to compromise on anything and everything.  Who cares about the Unix philosophy of doing one thing, and doing it well?  "That results in something that's different from Windows!" is the underlying message.  "We must unify everything so that it becomes more like Windowsis more intuitive to the user!"  IOW, they wanted to bring Linux back to the very world I had decisively left in the 90's and never want to return to.

And so I found Devuan and left the systemd world behind.  Hardly anybody has heard of Devuan in my social circles, let alone know what it is.  Do I care?  Of course not.  At this point, I'm ready to leave it all behind to adopt an unknown niche OS -- if it cares about the empowerment of the user rather than the empowerment of the upstream.  I don't care if nobody has heard about it or even knows what it is.  I don't care about systemd, snap, cross-distro unification, or any such similar nonsense that has been hoisted on the Linux world in the past 2 decades.  If I have to give up 80% of popular software, so be it.  I did it in the 90's, I'm ready to do it again.

And I believe I'm not the only one.  Let the majority of today's so-called Linux crowd go the way of Poettering, I'm sure a minority will reject it and take a different route.  We will fork the Linux ecosystem and leave the unified world behind. ("Unified world" is an euphemism for "dystopia under the control of a few who took it upon themselves to control everyone else".)  We will develop it in a wholly different direction, where the empowerment of the user matters more than the agenda of the few.  The machine should be humanity's tool, not the other way round.  To hell with popularity, I will fight for my control over the machine.

Have you noticed that the phrase "the IRS" spells the word "theirs"? 

A bunch of crows were perched on a tree, eyeing a piece of food that someone dropped in the middle of a busy road, and wondering if they should risk flying down to get the food.

It was a tempted murder.

I generally listen to what my wife says, but when she told me to stop imitating a flamingo, I just had to put my foot down.

What's the most terrifying thing in the science of nuclear physics?

The word "oops".

Speaking of facial hair, I was never a fan of beards, but then it grew on me. 

Remember the kid who boasted that his sister could play the piano by ear?  His friend said, That's nothing; my brother can fiddle with his whiskers!

Now why would his brother want to do that?  Because he likes violins so much he moustache it!

Unfortunately, he was eventually banned from the jazz band. Too much sax and violins.

Agent: Do you have any luggage to check in?
Sun ray: No, I'm traveling light.
