Not going to create a mirror from a link, just need to find links to files with specified filters and download them. Before firefox quantum there were many useful addons with good functionalities and they've been disabled or not yet ready in firefox quantum, like Flashgot which could do the job. I need to click on such menu items in context menu and use their functionalities:
I've used Download Star addon and found it not as good. It didn't download all links while it could find all of them. The filter works well, but they're not all downloaded. The next time I retry, I see that it doesn't try again. I need an exact alternative for FlashGot addon or find a way to activate it on firefox quantum.
