By: Shizu
Replace character names in novels and fanfiction with your preferred names. Perfect for personalizing your reading experience on any website. Simple, fast, and works on both desktop and mobile Firefox.

Features & Capabilities

Novel Name Replacer allows you to replace character names on any webpage. This extension is designed for readers who want to customize names while reading online novels, fanfiction, or any text-based content.

Features: Multiple Replacements Add unlimited name replacement pairs. Each replacement consists of an original name and the text you want to replace it with.

Manual and Automatic Modes: Choose to apply replacements manually with a button click, or enable automatic replacement that applies changes when pages load.

Persistent Storage: All replacement pairs are saved in your browser and persist across sessions. You don't need to re-enter your preferences.

Whole Word Matching: The extension uses word boundary detection to ensure only complete words are replaced. For example, replacing "Harry" will not affect "Harryton".

Case-Insensitive: Replacements work regardless of capitalization. The original text case is replaced with your specified replacement.

Cross-Site Compatibility: Works on all websites without requiring per-site configuration. Common sites include Archive of Our Own, Wattpad, FanFiction.Net, Royal Road, and other reading platforms.

Mobile Support: Fully functional on Firefox for Android with a touch-optimized interface.

How It Works: Open the extension popup from your browser toolbar Click "Add Replacement" to create a new replacement pair Enter the original name in the first field Enter your preferred replacement in the second field Either click "Apply to Page" for immediate replacement, or enable "Auto-replace on page load" for automatic application Remove individual replacements or clear all at once as needed Technical Information Browser Compatibility Requires Firefox 79 or higher. Compatible with Firefox for Desktop and Firefox for Android.

Performance: The extension processes text nodes in the DOM using tree walking. It skips script, style, and input elements to avoid breaking page functionality.

Dynamic Content: Includes mutation observer support to handle dynamically loaded content on modern web applications.

Privacy: All data is stored locally using Firefox's storage API. No external connections are made. No user data is collected or transmitted.

Use Cases: Fanfiction Reading Replace character names in fanfiction to personalize stories or use names you prefer over canonical ones.

Accessibility: Simplify complex character names or replace them with easier-to-read alternatives.

Reader Insert Stories: Replace placeholder text like "Y/N" with actual names in reader-insert fiction.

Limitations: The extension modifies page display only. It does not change the underlying HTML source or affect search functionality on websites. Changes are temporary and revert when the page is reloaded, unless auto-replace is enabled.

Privacy Policy: This extension does not collect, transmit, or store any user data externally. All name replacement preferences are stored locally on your device using Firefox's storage API. The extension does not make network requests, does not include analytics, and does not track user behavior.

Very easy to use! I hope that there will be an export/import database (as in the words that we have inputted) so we don't have to manually input them one by one when we move or use another device.

My experience with this extension so far has been delightful! Having unlimited name replacements is the best feauture!! I'm glad I can immediately apply a name change without having to reload, plus have it immediately (with the automatic replacement) upon reloading. The option to have the name change regardless of capitalization is a wonderful feature! Also, you don't have to remake a list of changed names as it saves your list! There are some names (words) where I wish I'd be able to have the capitalization match it as it is in the original text. In the following—sprinting was changed to fleeing: The horse was fleeing across the field. --> Sprinting across the field was a horse. This is an example of sprinting being used in the beginning and the middle of a sentence, but as it is not a name, having it change to lower-case/upper-case accordingly would fit different places in a text (maybe an optional box could possibly be put in place like how, name change regardless of capitalization, option is). The only problem I've encountered, is when a name I've changed has a punctuation mark attached to it, it'll revert back to the name I wanted changed. For example, Sarah is changed to Laura: Sarah. (Instead of ->) Laura. I'm unsure if this could be fixed, that would be nice! In conclusion, this extension works wonderfully and has a variety of utile features. Highly recommend. Edit: In case anyone is wondering, I am on FireFox mobile (Android).
