Review summary

Update Scanner is highly useful for monitoring page updates and is praised for being simple and free. However, many reviews note that it is no longer maintained, leading to reliability issues (blank pages, missing changes, deleted alerts) on many sites. It remains usable for some pages and for long-time Firefox users who rely on it, but compatibility with newer Firefox versions and OS setups is a concern.

Pros

Extremely useful for monitoring pages for updates and changes.
Simple, lightweight, and free to use.
Still works for some sites and remains valued by long-time Firefox users despite lack of updates.
Popular among Firefox users and considered essential by some.
Easy to use and quick to set up.

Cons

Maintenance has been abandoned; development stopped years ago.
Reliability issues across sites, with many pages loading blank or not showing changes; alerts can disappear.
Compatibility with newer Firefox versions/OS can cause UI problems (e.g., panel issues on Win11/FF117).

2025-05-13	Da*****	Because of the negative reviews I see, I want to confirm that this addon is still working as intended (actually with FF 128.10.0esr). I don't experience the problems others are referring to. So, this remains one of my favourite addons, and the main reason for staying with FF. Just wished a Chromium version would exist
