User Reviews
User feedback is mixed: several users find the add-on effective and fast for regex searching (including large pages and targeted tasks), while many others report it fails or misses matches on complex pages. Common complaints target usability (clunky UI, no auto-scroll/keep-open, output options) and occasional stability issues under heavy use. Pros
- Works well for many users — able to find regex matches in pages (including YouTube)
- Fast performance on large pages compared with other extensions
- Useful for advanced/targeted searches (supports complex regex)
Cons
- Unreliable for many users — reports of it not working or missing visible text, and problems with frames/iframes or complex pages
- Usability shortcomings — clunky UI, no auto-scroll to results, can't keep the panel open, and limited output-format options
- Stability concerns when driven hard — can freeze the browser if overloaded

Is Regex Search 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.
Regex Search requires very minimum permissions.
Risk impact analysis details
- High Allows reading and modifying clipboard content, which can be sensitive, posing a moderate privacy risk.
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.
Regex Search has earned a fairly good reputation and likely can be trusted.
