User Reviews

Users generally find cat-catch very useful and effective—particularly for downloading encrypted HLS and sites like Bilibili—but multiple reviews report stability problems (stops working, memory leaks) and practical limitations (mobile support, local-only/2GB limits). Reviewers also ask for continued maintenance and updates.
Pros
  • Consistently praised as very useful and easy to use (multiple reviews calling it "very good"/"great" and long-used).
  • Can download encrypted HLS and works with video sites (explicit mentions of encrypted HLS and B站/Bilibili).
  • Well-regarded by users who rely on it for video capture tasks (several positive endorsements).
Cons
  • Stability/reliability problems reported (extension stopped working and a memory-leak in v2.5.1 causing huge Firefox memory use).
  • Functional/compatibility limitations mentioned across reviews (mobile not supported; restrictions like local-only viewing, inability to move files and a ~2GB limit were noted).
  • Users expect continued maintenance/updates (requests for ongoing updates and issues implying need for fixes).
Recent reviews
Best video capture and downloader. Can download a lot of websites that other downloaders cannot. Recommended!

缓存捕捉太无敌了!最强大的资源嗅探工具。虽然对于一些简单的下载可能不如其他工具易用,但是提供了各种捕获方式供用户选择,在其他工具没用的时候属于是救命的大保底。

Is 猫抓(cat-catch) Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

猫抓(cat-catch) requires a lot of sensitive permissions. Exercise caution before installing.
