User Reviews

Word Replacer Max is generally well-liked for effective word substitutions and domain-based targeting. It works on desktop and on some mobile browsers (Orion), without slowing the browser or breaking pages. Examples like film→movie and Trump→the Idiot illustrate its practicality. However, mobile support is inconsistent across browsers, and the algorithm’s broad matching can cause unintended replacements (e.g., you/your). Overall, it’s a simple, useful tool with room for refinement.
Pros
  • Reliable word replacement across sites (e.g., film to movie; Trump to the Idiot).
  • Per-domain replacement controls (domain-based enabling).
  • Does not slow the browser or interfere with websites.
  • Desktop reliability with some mobile support (Orion).
Cons
  • Mobile support is inconsistent across browsers and not available on Firefox mobile.
  • Broad word matching can cause unintended replacements (overlaps like you and your).

Perfect. The world replacement works. The ui is flawlessly desinged, even with a dark mode. Best feature is the domain list filter. That's perfection right here. Love it!!!

Is Word Replacer Max 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.

Word Replacer Max requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details
  • Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.
  • High ******* ******* **** *** ****** ***** *** ***** ** ******* **** ********* ********* ** * *********** *****
  • Low ******* ****** ** *** ********* ******** *******************
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.

Word Replacer Max is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
