- by Firefox user 13845986, 4 years agoRated 3 out of 5This was my epub web page grabber, But.
The Firefox (56.0) legacy ext. worked well, could added articles, pictures etc with "Sigil" to my older epubs.
Now "GMB legacy" doesn't work with Firefox 57.0 => and your stuck with "GMB Desktop" which has to be running first before you can capture with the supposed "EXT." (two downloads to work??) though it does work in my Chrome Browser admittedly, but with the same hastle.
And don't ask about the withered option menu...
