Daily annoyance? Yes! The pre-roll ads on YouTube didn't get blocked anymore by my blockers of trust (Ghostery & uBlock Origin) so I decided to write my very first add-on for Firefox. I've never touched JavaScript or add-ons before - but with the help of ChatGPT I got it working over the weekend [1] and now watch my YouTube videos without any ads. (I also did a version for Chrome, still waiting for approval)
I still sell about two copies/month of PostMe, a (german) desktop email client. The core is 16-bit code written in VB3 that dates back to 1996. It runs fine under WinXP and Win7/32.
