User Reviews

Users appreciate Word Replacer's straightforward interface and the feature to import/export rules and organize them into groups for selective use. It effectively replaces words to customize content, improving user experience. However, several users report problems with React site textboxes where typing becomes difficult due to cursor jumps, and occasional text clipping when replacement words are longer than originals.

Pros

Simple and easy-to-use interface
Ability to import/export rules easily
Supports grouping of rules into pages for selective activation
Effectively replaces words as intended and enhances browsing experience

Cons

Causes issues with textboxes on React-based sites like Facebook and Discord, moving cursor to start when typing
In some cases, replacing shorter words with longer replacements can overlap or clip into adjacent words

Recent reviews

The replacement of words works but the plugin definitely needs some finetuning. For example the word list stays blank even after adding rules (the rules are applied though). Also it would be essentiel to implement a white list for certain domains.

It does what it says it'll do, and does it well. Easy to use, too. Only problem is, I've noticed that pages with large amounts of text load... extremely slowly with it turned on. Wikipedia pages can take minutes to actually become usable. So, keep that in mind I suppose.

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