Useless, the button does nothing.

It's not working.

Do nothing after click

blank page new tab why?

Does what it says. Finds all files including js, jpg, gif, css, etc.
I had one problem after installing, just like Не работает writes: it opened only empty tabs. After removing a legacy extension, it worked. I don't remember which extension it was, but it was a legacy extension.
So if it doesn't work, you may try disabling legacy extensions.

All what this addons do - open empty tabs. I try a difrent version of Firefox - no result.
Link Gopher is better.

Genau was ich gesucht habe! Dieses Add-On ist mir eine große Hilfe!

Please update support for new versions FF (55+)
