Not always working.

I keep on downloading it in my system and it keep keep removing itself from my computer.

Works intermittently on Firefox Quantum 62.0.3 (64-bit), therefore I question the point of paying for a premium service.

Uses too much ram. Its nearly impossible to use it on outlook. There is too much emphasis on UI and very little attention is paid to UX.

WHEN IT WORKS ITS GREAT BUT ON FACEBOOK A LOT OF TIMES IT DON'T WORK,WOULD LIKE TO KNOW HOW CAN IT WK,ALL THE TIME.

Not work with new edition gmail on firefox- but it works in chorme
