This is probably a dumb question but I didn’t know who else to ask– how do you reply to replies on this nasty blue hell site?

I have an xkit extension called ‘one-click reply’ so when I have a notification and hover with the cursor over it, there’ll be a ‘reply’ button that I click. however, tumblr has made that much more difficult for a week or so because usually I could do that in the activity feed as well but for some reason they changed the activity feed up to make the symbols bigger (????? tumblr what????????) and since then none of my extensions for the activity feed are working anymore 😦 can’t read the tags on reblogs or reply comfortably. it’s stupid as fuck.
