As of late I stopped seeing TL bubbles on posts marked as TL'd, is there a setting I need to enable or is it my browser(firefox 71)?

Enable the console (Ctrl+Shift+K), reload the page and check if there are any messages about not being able to load some JavaScript from cdnjs.cloudflare.com.

Also, which region in the world do you access Danbooru from?

Also also, take the chance to update to Firefox 76, even though that won’t fix your problem. ;-)
