I've been waiting for Linkclump to come to Firefox ever since Foxifie stopped working a few years back. I set it up quickly, and it works perfectly as it would on Edge or Chrome. Thank you for what you do and I hope this continues to be updated in the future.

Edit: After using it a bit it seems the tab function, when multiple tabs are being selected, isn't working like the Chrome version. When I select open tabs at the end, it seems to want to go to each tab as they open and I don't want that. I want them to open in the background, but if I select open in background the tabs then won't adhere to the open at the end checked box. Not sure if that's fixable or not. Just wanted to relay some feedback.

Edit 2: Hmm nvm. It works as it's supposed to. Not sure why it didn't the first time, but I uninstalled the app, reinstalled, set up everything, exited the browser completely, reopened and boom it worked. Guess firefox was being a bit weird.
