This is malware. Consumed up to 8GB of RAM for no reason. Do not install.

I've not checked that extension was doing, but it does some background job because a CPU was loaded even though only one blank tab is opened. More over seems the extension isn't working.

Causes high CPU usage!

Insane high cpu usage. Do not install or your pc will get bloated

Dieses Add-On verursacht eine außergewöhnlich hohe CPU-Auslastung. Es scheint dauerhaft im Hintergrund zu laufen, sobald der Browser gestartet wird.

high cpu usage

Insane CPU usage. Not recommended.

A LOT of CPU usage, removing the addon reduced CPU usage by about 60%

afer long digging on what is constantly eating my CPU resources even without browsing at all, I found it is this addon

Very high CPU usage. Makes my computer slow to a crawl.

Huge resource problem... Memory leak ?

high cpu load and ram usage for no reason

It does what it needs to do, true. That's why I won't rate it it with a single star. But it is causing an insane CPU use on my Mac, draining my battery within an hour. Took a lot of work to find out the cause. Please fix this ASAP!

花兩天時間，以爲是firefox更新造成用掉一核的cpu，安裝舊版的firefox狀況一樣，一個個將附加元件停用終於抓到這個11月6日更新造成，這個問題明顯又嚴重，您們釋放新版本沒有測試。

Massive resource hog. Why? It took me forever to figure out which extension was hitting the processor so hard in comparison to everything else, and it turns out to be this one.

Hey, developer. What gives? It works great, but at what cost?
