Review summary

Overall, reviews praise the add-on for ease of use, power, and a Stylus-like workflow that makes managing JavaScript on pages approachable. The main benefit is enabling user scripts without Mozilla submission and enabling automation like auto-scrolling, as well as content blocking. Reported drawbacks are relatively minor and not widespread, with occasional site compatibility issues and a small editor quirk noting that an empty script save can occur, plus occasional local-file limitations mentioned by some users. The sentiment is largely positive, emphasizing versatility and convenience for customizing page behavior with JS.

Pros

Easy to use and user-friendly interface.
Very powerful and flexible for injecting JavaScript on pages, including automation (e.g., auto-scrolling) and blocking content.
Stylus-like workflow for JavaScript, familiar to CSS users.
Convenience features: can load personal scripts without Mozilla submission and supports auto-loading bookmarklets.

2026-01-12	da*****	Very good. But I'd like to know if it's possible to create a script that runs on all pages. I'd like to implement a dark mode that activates when a button is pressed. Also, I'd like to know if it's possible to specify the DOM tag when adding the script. I was using a polyfill, but since it runs last, I had to reload the other scripts for them to run without errors.

2025-07-10	R.*****	I had a small extension I wrote for myself modifying a site to my preferences and was annoyed I could only load it as a temporary extension without submitting it to Mozilla. This is exactly what I needed, thank you.
