Review summary

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)

2026-05-05	Sh*****	Hello Devs, Thumb Rule: Changes pushed to production must not degrade user experience. If a release impacts multiple users, immediately assess severity and deploy a hotfix faster and if you can't there is always an option to roll back the changes so that devs get time to fix and user experience remains intact. It's been a while and feel you guys need time to fix, So why don't you revert changes from previous release 6.12.1 that are causing leaks? This will help us use the extension without worrying. I was about to completely uninstall firefox because of the problems wappalyzer created.
