The extension that sabaraha suggests, would give you just what you were used to (and more) - why don't you just give it a try  ? Might put the smile right back on your face  !

Changes : some hate them - others love them .....

However, maybe you'd like to submit feedback here :

The fact that there is an extension to fix it says it all lol, ‘leave things alone’ we use Firefox for a reason , don’t fix things that don’t need fixed lol, why would anyone want a other bookmarks as default lol , errmm!!

Contributors on this support forum are (for the main part) volunteers, users just like you, trying to help other users in their spare time. We're neither Mozilla employees nor developers - hence I suggested you'd submit feedback on the pages I gave you links to.

I appreciate your frustration though, but (call me stubborn) : would you give that extension a try  ? Just might put a smile on your face, once you've got things working again the way they used to ......
