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.

2025-07-15	Ja*****	Could be better if it doesn't automatically closed when the page is reload just like the inspect elements it doesn't automatically close. Please fix this.

2025-07-15	Vi*****	Better than nothing but not really usefull. The network tab is useless. It is empty when the extension starts and the extension will disappear when you reload page. So only lengthy deferred loading will show up. I guess this is the same for js errors. Source code has no color highlighting (listed as a feature ???) and you can't select parts of text. Console has no code completion. So what is left ? You can execute js on the fly and you can browse the content and cut/paste nodes.
