## Review summary

The dominant, recurring problem is that Firefox cannot open the Quillbot extension due to an embedding/security restriction, rendering the add-on unusable on Firefox. Several reviews note the same error, while Chrome/Edge seem unaffected. Additional concerns include unhelpful support pages, no official Firefox extension yet (with scam warnings), and overall inconsistency in Firefox versus other browsers. A minority still appreciates the underlying paraphrasing/features when accessible, but the Firefox bug prevents practical use.

### Pros

- When functional, the tool provides strong paraphrasing and writing features (paraphrase, plus options like summarize, translate, citations, plagiarism checker, and grammar checker).
- The premium option is described as not expensive, offering value for paid features.
- Overall potential usefulness when working (users see value in the service despite the Firefox issues).

### Cons

- Cannot open or load the extension in Firefox due to a Firefox security/embedding restriction (embed/embed-page issue).
- Extension does not work in Firefox because the page cannot be displayed, with the common error about embedded content.
- Support resources are unhelpful or mostly promotional (advertising on the support page, lack of concrete help).
- There is no official Firefox extension available yet, with warnings about potential scams; users are advised to be cautious.
- Functionality works in other browsers (Chrome/Edge) but not in Firefox, indicating cross-browser incompatibility or Firefox-specific blocking.
