With Video DownloadHelper extension enabled if I go to the Xfinity Stream website to view live TV programming after about 70 minutes Firefox starts slowing down and the live TV starts to play intermittently. The only way I can watch Xfintiy Stream live TV is to disable Video Download Helper.

Outstanding down loader. Vastly superior to all other downloaders I've tried over the years. Extremely versatile and user-friendly. Definitely earns 5 Stars from me! Absolute must-have! One of the best!

top notch

SIMPLEMENTE LA MEJOR EXTENSIÓN DE DESCARGA Y MUY FÁCIL DE USAR

Excelente! Adquiri a licença para windows... E quando fui adquirir para um outro PC com linux, fui surpreendido em saber que para estas distros é gratuito. Parabéns para equipe que desenvolveu e mantém ele em perfeito funcionamento. Abraços.

Absolutely stellar, the quality of the videos it records is excellent. Give these guys a raise!

不错，不错，

GOOD ADD-ONS EVER!

Je l'ai utiisé dès son appparition, même acheté la license... le meilleur et facile à utiliser.

Excellent addon!!

Add-on molto utilie e che funziona benissimo. Lo consiglio vivamente.

I don't know how well this addon downloads videos- I already have a dedicated Youtube video downloader- but what this addon did do is completely ignore every other video site I visited while also nagging me to download an extra piece of software (which mozilla naturally won't QC) and destabilize firefox to the point that it would frequently crash after roughly 30 minutes or so.

verdict: literally less than useless, because it adds nothing but also takes away functionality. uninstalled

Świetny dodatek. Bez najmniejszych problemów ściąga pliki video wycinając przy tym reklamy.
