I noticed one of the greasemonkey script stopped working, Tumblr Hide Post. I checked the options, and I realised there was the same name in this code than in the html creating the boxes. I took Tumblr Hide Post off, and it seems to work now.
Thanks for the info!
But how do you find “Tumblr Hide Post” to even take/turn it off? Is it part of individual posts or settings..?
It’s in the tool/add-on menu of firefox for me.
