So simple and nice, that I don't understand youtube never implemented this feature Puntuado con 5 de 5 estrellas

It does exactly what you expect. And for people finding this plugin, is probably thinking, is there a plugin to make me avoid garbage videos on youtube. This will help in a big way.

L'extension est stable et rapide, je vous la conseille fortement !
Gros merci au développeur pour cette extension formidable !

This Provides a much needed time saver feature that YouTube deliberately hid to for their own profit. I can now know if that video has a false description (Too much of those!) or not before clicking it.

Does not work version 42 Puntuado con 1 de 5 estrellas

I have tried this on Linux Mint and Windows 10. I cannot seem to get this addon to work. I did try another YouTube preview addon and that seems to be working. Not sure if support has ended for this addon since it used to work prior to Firefox update.

Hi FirefoxLinux1031, can you confirm if the last version of the addon is still not working for you in Linux?

A must-have extension. Makes it far easier to quickly find the good videos on Youtube and ignore the bad ones.

Works great. Had it modified slighty but Youtube changed something in September so my part doesn't work anymore strangely enough. But this 'YT rater' is the best out there for sure.

I love this addon and I've been using it for years, but as of Firefox 28 it simply hogs the whole CPU and Firefox just hangs for 5+ seconds every 10, which is not cool. I've left you a bug report in the google code website, I hope you'll be back to fix this. If not, I'm still grateful I've been able to use this for so long. Best.
EDIT: Thankfully the author has released a new version which is way better. Hopefully it'll keep improving =)

This seems to happen only on Linux under some circumstances. Will have a look in the next weeks. Sorry for the wait.

Simple, lightweight- *two thumbs up* Puntuado con 5 de 5 estrellas

NICE THINGS:
_Should *totally* be a part of YouTube natively.
_Easy to configure.
_Saves from the regret of "uuggghhh, waste of time!" on YouTube.

WOULD-BE-COOL:
_Custom colors would be keen. I have eye problems and have a heavily-modded color theme for everything on my computer. However, the supplied color schemes do the job (I totally dig that the opacity can be configured as well)
