The **Profile Switcher for Firefox** needs a serious update or to be forked, as the GitHub repository hasn’t been modified in two years. With Chromium-based browsers moving to Manifest V3, the need for Firefox customization becomes even more critical. To keep up, Firefox needs to reintroduce the user-switching feature that many are accustomed to from Chromium-based browsers. Currently, Firefox does support:
1. **Casting to Device** , 2. **Making Individual Web-Based Windowed Browsers (SSBs)**
However, **switching between users** is a crucial feature that Firefox lacks right now. Users are seeking this functionality, and if they can’t find it in Firefox or through third-party solutions, they may turn back to Chromium-based browsers. We should not let YouTube and Chromium outpace Firefox in providing essential features like fast user-based switching.
