Hi! Do you have third-party cookies disabled? If so, you may need to add an exception for notion.so in your Firefox settings. We use a cookie to track whether you're logged in, and it registers as a third-party cookie because the extension's active domain is a moz-extension:// URI and not http://notion.so.

To add an exception for the Web Clipper:

1. Open Firefox Preferences > Privacy & Security > Cookies and Site Data > Manage Permissions
2. Add "notion.so"
3. Click "Save Changes." (This step is important! Your preferences won't be saved otherwise.)

You should be able to use the Web Clipper now. If you have further questions, feel free to reach out to team@makenotion.com, on Twitter at @NotionHQ, or via Intercom chat in the app.
