    the original plan was to self-host my blog and write there but lot of stuff happend and i still haven't created a self-hosted blog. so i will stick to dev.to for my next posts as my good old waterfox classic browser was killed by "overjavascriptification" from all sides. now i am on a browser mix of my good old waterfox, librewolf and ungoogled chromium. i will evaluate thorium and mercury next. why don't i use the regular firefox? because i really don't like the direction mozilla is going to. the last wtf was the implemenation of some kind of tracking which is opt-out and not opt-in.
