Review for Extension List Dumper by MarkRH
Rated 5 out of 5 stars
Great add-on but it seems that with FF19 and v1.15.2 of this that all the files are being saved as Read-Only for some reason. The folder where they are being saved is not read-only and I can save files from other programs there that are not made read-only. Weird. I sent in a support email a week ago with no response so asking here.
