User Reviews

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.

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.

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.

Is MobiDevTools 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.

MobiDevTools requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

MobiDevTools is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
