Do you have any Amazon add-ons (extensions) installed in Firefox? Did you, or someone who uses your computer, install any software recently?
If it is a Firefox add-on causing the issue and you have more than one that could be the culprit, start by disabling all of them. If that fixes the issue, then it is just a matter of enabling each add-on (one at a time) to discover which one is causing the issue. When you figure out which one it is, uninstall it.
While I will be the first person to admit that I don’t completely understand either, the concept is pretty simple.
Think of a digital recording being something like sheet music. Sheet music is a set of instructions on how to play a song that anyone who knows how to read music can reproduce.
Digital recordings work in a similar fashion. The playback device reads the instructions which include things like frequency and volume, and is able use that information to make a perfect playback of the digital recording.
Could it be recreated by random chance? Sure. Would it? Probably not. At least not easily.
Fun fact: a small amount of vinegar in the cooking water helps to keep potatoes from getting mushy.
I like my Crocs, but for me they are not a very good shoe for my feet.
I have one pair of Crocs that I bought last year. First thing I noticed was the textured footbed. It’s kinda spiky and not very comfortable to me. I have been amazed at all of the comfort claims due to this. You can and do get used to it, but the first couple of weeks is not comfortable at all.
Also, I’m a big guy and Crocs don’t offer much in the way of arch support. I have never had arch issues until I wore Crocs on a regular basis.
Here are a few suggestions:
Volunteer at a soup kitchen or a food pantry
Sign up for a church email newsletter and go there when they are doing pot-luck meals (bring a dish to pass)
If you are into sports, sign up to volunteer as a coach.
Don’t buy all of your groceries all at one time. Buy a few things each time and go more often. Even if you don’t meet or talk to anyone but the workers, you will be around other people.
