This problem seems to be at least over a year old with no apparant solution. I've been trying to dl vids from a subscription site for several months now. Currently using v7.2.2. As others have previously said the video takes X number of minutes to download but there is only a 1kb (48 byte) file in the dl directory. Therror data shows:
moz-extension://7327f3f4-eb0a-4470-a3f6-52d69c1e26ad/background/main.js:1
value@moz-extension://7327f3f4-eb0a-4470-a3f6-52d69c1e26ad/background/main.js:1:213919

value/t.endTimer<@moz-extension://7327f3f4-eb0a-4470-a3f6-52d69c1e26ad/background/main.js:1:172600
If that helps.
Any suggestions or work arounds? It doesn't matter what resolution I try to DL or if I use the companion or browser to DL. VDL works fine in other sites, just not this one.
