User Reviews

Users praise the add-on for actual text replacement, full-page scope, and a simple, lightweight design. But the top drawbacks are a duplication bug, limited cross-site support/maintenance, and missing advanced features like saving patterns and shortcuts. Overall, it’s a handy, quick-find-and-replace tool for simple tasks, with room for broader site compatibility and more control features.

Pros

Actual text replacement (not just a visual change) inside text boxes and on webpages.
Replaces all occurrences, not just the first match.
Simple, lightweight tool with a small footprint and easy to use.
Works in contexts where other tools fail (including dynamic content and iframes after updates).
Developer responsiveness and improvements (notably updates that expanded support).

Cons

Duplication bug in recent updates causes replacements to be applied twice.
Limited cross-site support and maintenance; perceived as not working broadly (sometimes Google Translate only) and not updated for a long time.
Lacks advanced features and controls (no save/favorites/history, no keyboard shortcuts, limited customization).
If used to replace many terms at once, it can be risky due to lack of granular control.

Is Replace 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.

Replace requires very minimum permissions.

Risk impact analysis details

Medium Enables sending notifications which can be spammed but have minimal direct security impact.

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.

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