Download YouTube Videos as MP4

Latest version is great on Firefox, has problems with SeaMonkey Rated 4 out of 5 stars

Works great in Firefox. No issues, and I can download youtube videos for offline viewing to my heart's content.

The latest version (1.6.4) doesn't seem to be compatible with SeaMonkey as it prevents links from loading and new tabs from opening. I noticed that there are no SeaMonkey versions listed for 1.6.3 and 1.6.4, but for some reason several computers auto-updated from 1.5.18 to 1.6.4 anyway. A manual downgrade to 1.5.18 fixed the problems.

Almost perfect Rated 4 out of 5 stars

Light, fast, unobtrusive, and now works on the latest Firefox and Seamonkey. Only quibble is images in remotely stored books sometimes don't get completely rendered -- the top part of the image will show, and the rest will be blank. Otherwise, perfect for my needs.

Great on Seamonkey 2.14 / Firefox 17 .. Rated 4 out of 5 stars

Fairly fast and unobtrusive EPUB reader, it works like a charm in Seamonkey 2.14 and Firefox 17. Unfortunately, Lucifox (0.9.4) seems to need some updating for Seamonkey 2.15 / Firefox 18 compatibility. Reading locally stored epub files still works, but the Lucifox extension has problems reading files located on other servers. This problem extends to files linked to in the OPDS catalogs.
