## Review summary

MobiDevTools is appreciated as a valuable mobile Firefox developer extension that allows JS execution and content inspection. Users find it simple and helpful for tasks like uBlock filter creation. However, common issues include the extension closing on page reloads, an empty network tab at startup, inability to edit HTML live, and UI bugs such as missing shortcut buttons and display problems. These issues impact usability but the extension remains useful for many mobile developers.

### Pros

- Useful for mobile Firefox users, especially for development tasks like creating uBlock Origin filters.
- Allows executing JavaScript on the fly and browsing content nodes.
- Simple and generally works as expected.
- Valued by some users who have used it for years and consider it the best tool available on mobile Firefox.

### Cons

- Automatically closes or disappears when the page reloads or redirects, causing loss of network data and console information.
- Network tab is often empty upon starting the extension, limiting its usefulness.
- Cannot edit HTML in real-time, which some users desire.
- UI issues such as shortcut buttons not appearing on new pages, theme and settings not applying across domains, and screen width adaptation problems with content cutoff.
