User Reviews

Overall, reviews are mostly positive: users say the add-on works, is easy to use, and is highly regarded for recon tools. The most consistently reported downside is installation issues, with several users seeing 'Installation aborted because the add-on appears to be corrupt,' including on Linux Flatpak. There are no widely repeated functional complaints beyond installation errors. A few reviewers warn about misuse or malware claims, but those are not common across reviews. The tool is generally seen as useful but with platform-specific installation problems.
Pros
  • Works as expected for recon tasks
  • Easy to use / user-friendly
  • Strongly regarded for recon tools and websites
  • Generally considered a good/best extension by users
Cons
  • Installation aborts due to the add-on appearing corrupt (repeated across multiple reviews)
  • Compatibility/installation issues on Linux Flatpak (non-working or problematic installation)

Is Wappalyzer 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.

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

Risk impact analysis details

  • High ******* ******* **** *** ****** ***** *** ***** ** ******* **** ********* ********* ** * *********** *****
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.

Wappalyzer has earned a fairly good reputation and likely can be trusted.
