So I have seen this for awhile and had not mentioned something before partially because its not a game stopper and so many things are going on with piefed dev I hated to bother. I kinda expected other people would be seeing it and it would likely get attention and maybe it has but I just have not seen it. Anyway I attached a screenshot showing how the dropdown menus get obscured by the site and its not just obscured because the site under the dropdown seems to have interaction priority. The funny thing is when I click on images and get the larger version like sometimes something like this happens and at other times the pop up image will correctly be in front of everything. Im not sure if its the type of image or what but the effect does not always happen with pop up image. It basically always happens with the drop downs though. I changed to default theme and some other themes and this issue consistantly happens.
Are you using noscript? If you are, then things won't render properly if you don't allow the JavaScript. I'm asking because it seems you have the noscript symbol showing in the screen shot and I've seen the same thing a hundred times when I haven't whitelisted a lemmy, PieFed, mastodon, etc. JavaScript.
I was allowing everything. Definately one of my add ons but so far not sure which one. enabling and disabling them all caused it to go away.
@rimu@piefed.social ok I am fairly certain its no script. Even though I allow everything that appears for piefed standard stuff it goes away if I disable restrictions globally. the main reason I use firefox though is for no script so I think I will just live with it.
