## Description

## Review summary

The Clear Cache and Data Firefox add-on is appreciated for its ability to selectively clear browsing data and speed up the browser, giving users configuration options not present in Firefox's native tools. However, multiple users complain about it unexpectedly deleting saved passwords, causing pop-up windows to hang, incomplete clearing of some data types, and requiring more clicks than native options. The lack of clear feedback on successful clearing is also a noted usability issue. Despite problems, many find the add-on useful for customized clearing of browser data.

### Pros

- clears selected browsing data effectively as promised
- allows selection of which data to clear each time it is used
- can speed up browser performance by clearing cache and data
- configurable and useful for selective clearing rather than a one-click clean
- works with Firefox versions 42.0 and later according to some users

### Cons

- removes saved logins/passwords (logins.json) unexpectedly and without warning
- pop-up windows can get stuck or do not close automatically after clearing data
- does not always clear downloads and offline website data effectively
- requires multiple clicks (around 4) to clear data, which is more than native Firefox clearing dialog
- lack of clear notification or confirmation after clearing data leading to confusion
