Linkchecker For Firefox Quantum?

I love the new Quantum version of Firefox. My sole complaint is that my favorite linkchecker https://addons.mozilla.org/en-US/firefox/addon/linkchecker/ no longer works. I really, really, want an extension/add-on link checker and not a separate program. Any easy suggestions or alternatives?

I have a website with literally hundreds and hundreds of links. I used the linkchecker shown above and once you activated it, it automatically scanned the each page and checked each link. I don't want an option where I have to manually check each link.

Thanks,
LB

 

Any other browser have a good linkchecker extension that automatically checks all the links on a webpage? I'd be willing to use another browser for that task.

 

It is in a work setting and our IT have upgraded all of our PCs. I'd rather not change what they did. Can you install an older version of Firefox along side quantum on the same PC?
