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.

2026-06-13 ha***** Works as described. Replace method doesn't mess w/ Google Translated webpages' formatting, so I can use Stylus to get rid of those annoying paragraph indents. I use this extensively, and lists get very long. A function to insert an entry at a selected location would save so much time. Currently using a Auto Hotkey script as a workaround to position entries. Bug: After editing a list, sometimes the last list (or extremely rarely the first) gets overwritten with the edited list, losing all data. Unknown what causes this. Currently using empty lists as a buffer. New version prevents empty lists from being created, so as a workaround I have to import old blank entries (or just use the older version).

2026-04-26 Fi***** Usually works nicely, but need to explain how "match case" works. I want to substitute a word that can be either at the beginning or inside of a sentence. The case of that word must change accordingly.

2026-04-18 kt***** Looked promising but does not work for discohook for whatever reason. I'm sure it works great for other websites but I can't be bothered to try when I don't need this feature for other websites.
