## Review summary

Most reviews praise the add-on for decoding base64 directly on the page with no extra tabs and for being simple to use via the right-click context menu. It works well for ASCII text and decodes links/messages as advertised. However, a recurring drawback is the lack of Unicode/UTF-8 support, causing garbled output for non-ASCII content like Chinese characters, which limits its usefulness for multilingual text.

### Pros

- Decodes base64 directly on the page (no new tabs needed).
- Simple and reliable; works as advertised.
- Triggered via context menu (select text, right-click) for quick decoding.

### Cons

- No Unicode/UTF-8 support; non-ASCII text (e.g., Chinese) becomes garbled.
