User Reviews

Users praise Forecastfox for rich features and reliable behavior when using the working XPI versions and value the active forum help. However, multiple reviewers report being unable to change locations, frequent installation/signature errors ("corrupt"), lack of maintenance/updates causing compatibility issues, and occasional map or data-loading failures.

Pros

When using the working XPI versions (e.g., 4.25/4.26) the add-on provides full-featured weather and maps and functions well.
Many users consider it the best/most useful weather extension compared with alternatives.
Active community support and forum-provided manual fixes are available and can restore functionality (export/import settings, manual location edits).

Cons

Location selection is broken for many users — they cannot change from the default location.
Installation often fails with messages like "add-on appears corrupt" or is blocked because the add-on is unsigned.
The add-on appears unmaintained/outdated (no recent official updates), causing compatibility problems with newer Firefox releases.
Maps or data sometimes fail to load or show infinite loading/download-failed errors.

There is a version 4.25 and a 4.26 version floating around on the web. I had a really hard time to find the XPI file to download. Both versions work perfectly. My 1st PC updated to 4.26 automatically, i had this installed for quite some time. I did a fresh install of firefox on the 2nd PC and ran into problems with version 4.12 as it would not load the maps. I installed 4.25 file and it worked perfect.

This is still the best weather add-on. The current version is NOT corrupt - it just doesn't work because it has not been signed (and the creator lives in the Ukraine, so... *fingers crossed*). Thankfully, the folks in the support forums have figured out how to get it to load. It's still hands-down better than the next most popular option, so I highly recommend checking out the forums and installing it.

Is Forecastfox (fix version) 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.

Forecastfox (fix version) 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.

Forecastfox (fix version) may not be trust-worthy. Avoid installing if possible unless you really trust this publisher.
