I can't see the dashboard, edit, customize, etc. buttons on my own Tumblr blog. I can see them on other blogs and I can see them while using other browsers.
This problem started suddendly, it was fine until yesterday. I've tried changing my theme on Tumblr, unistalling all of my extensions, cleaning cache and even reinstalling Firefox again but nothing worked. I emailed the Tumblr staff and they told me that it's probably a Firefox bug.

Start Firefox in Safe Mode {web link} While you are in safe mode;
Type about:preferences#advanced<Enter> in the address bar.
Under Advanced, Select General. Look for and turn off Use Hardware Acceleration.
Poke around safe web sites. Are there any problems?
I've tried but nothing changed. I've found out that it's a common problem tho and it started with the latest Firefox update. I've downloaded Firefox 33.1.1 and everything works again.
I've called the big guys to help you. Good luck.
