Review summary

User reviews praise FoxReplace for powerful, fast text/script replacement with regex support, along with being simple to use and reliable. Long-time users appreciate its longevity and consistent behavior, including not disrupting formatting on pages like Google Translate, and the extension helps reduce on-page clutter. However, several reviews point to a learning curve and lack of clear documentation, with the UI not always intuitive. Some users also report that setup for automatic substitutions requires several steps and can be confusing. Overall, it's a solid, time-tested tool for on-page text replacement with room for UX improvements.

Pros

Powerful replacement capabilities (text/script) with regex support for fast, broad text substitution across pages.
Simple, clear, and easy-to-use interface for common tasks.
Reliable performance that matches expectations and generally preserves page formatting (e.g., on Google Translate pages).
Long track record and trust from years of use (around 11 years).
Helps reduce on-page clutter and distractions, improving reading experience.

Cons

Interface not intuitive and explanations/documentation are lacking, making it harder to learn and use for some users.
Configuration for automatic substitutions and managing replacement groups can require several steps and be confusing.

2025-07-22	El*****	The text replace functionality works well, but there is an issue with the changes to firefox which added vertical tabs and the 'show sidebar' setting. If we switch to vertical tabs or enable the sidebar then it adds an icon for this extension, and it cannot be removed or disabled. Please update the extension to fix this or tell us how to have the sidebar visible without the extension icon.

2025-07-02	Lo*****	So far working as intended but I will need to use it a bit more to see. I found that to add a group of words to replace or have multiple words replaced AND to automatically replace when loading a new page you need to: 1). Go to manage extensions 2). Click the 3 dots next to this extension 3). Hit options 4). For auto replacing, at the bottom of the options page at "Other Settings", check the box for "Apply automatic substitutions on page load" 5). To add a list of words, hit the blue "Add" at the top 6). Select "Substitutions" instead of "URLs" 7). From there you can add your words and their replacement and change the name of the list too 8). Hit "OK" and it should work from now on!
