Why this extension in taking clipboard access. I think its a security issue. I have removed this extension

Component backlight does not work

I can't install the tools

memory leak.

completely useless

The add-on doesn't work on websites which specify a Content Security Policy. There's been a bug about that open on GitHub since February 2020 (#17997), yet nobody cares enough to fix it. The project I'm working on specifies a CSP, so this tool is useless for me.

Unusable due to https://github.com/facebook/react/issues/22034

doesn't work for this website under firefox, funny.

in macOS, Usage of CPU is too HIGH and memory leak
