If you use Freetube, you haven’t failed to notice that Google is on the war path again and broke it a few days ago. See this bug report.
Please note that it’s been fixed in this PR. If you download the nightly build #5652, it now works like a champ.
Thanks team Freetube!
For sure, I use Libredirect on firefox to open all youtube links in freetube. There isn’t anything worth watching on youtube where I have to be signed in to see. Not worth the privacy loss.
