AI 产品解读Revert Facebook's visual appearance to the pre-September 2020 old layout by injecting CSS overrides
Users who dislike Facebook's modern UI redesign (rolled out September 2020) want to restore the classic Facebook color scheme and styling
User installs extension → extension automatically injects fb.css on facebook.com pages at document_start → content script (cs.js) verifies user is logged into Facebook, then signals background script to apply theme → CSS overrides change colors, fonts, and layout to resemble the old Facebook design
Injects CSS to change Facebook's color scheme back to the old blue header (#4267B2), old background (#E9EBEE), and old text colors (#385898)Adjusts font sizes and line heights to match the old Facebook layoutHides Facebook's new layout banner/upgrade prompts (e.g., .fbPageBanner.uiBoxYellow)Automatically applies on facebook.com home page with no configuration needed
- 目标用户
- Facebook users who preferred the pre-September 2020 classic layout / Users dissatisfied with Facebook's new design who want a familiar look
- Extension is very small and straightforward (CSS injection + simple JS checks), so the analysis is highly deterministic
- Cannot verify if the CSS overrides still work effectively with Facebook's current DOM structure
- Future themes feature mentioned in options.html has no implementation to analyze
付费分析未识别到付费功能
No payment platforms, billing APIs, subscription logic, upgrade prompts, or gated features found anywhere in the source code. The options.html popup mentions 'In a future update, you will be able to choose from hundreds of themes' but this is a forward-looking statement with no current implementation or monetization. The deterministic scan found zero paid keywords in actual code; the 'pro' hit was a false positive in the base64-encoded verified_contents.json.

- The extension itself has no login system or account requirement. It operates purely as a CSS injector on facebook.com pages. While cs.js lines 13-15 check if the user is logged out of Facebook and lines 40-45 check for Facebook's c_user cookie, this is a check for the user's existing Facebook session—not a login requirement imposed by the extension. The extension reads Facebook's own DTSG token and c_user cookie only to confirm the user is logged into Facebook before applying theme changes.
Does exactly what it says on the tin. Not sure about broader compatibility but i just use facebook for some groups and to keep up with friends and i haven't had any issues
Super :)
Great work :) hope it will work for long time :D
thanks all good
works great, didn't experience noticeable bugs so far
So in your video you said Facebook tried to take down your source. But basically all you do is tricking facebook into thinking you're an old browser, causing their OWN CSS to kick in and not yours. So all they have to do, is to not support that CSS anymore and your entire extension will stop working forever. I highly doubt you will be able to fix this as I'm currently looking at the source of this extension. Also, it shows an alert saying "The new Facebook layout will come to this browser soon". So rip your extension bud.
Perfect :D
Awesome
這個外掛真的讓使用者方便很多,不用再把電腦當作手機來使用,FACEBOOK一直在限縮PC使用者對於"電腦介面"的需求,既然FACEBOOK不聽PC使用者的需求,那麼就請大家用力支持這個程式。
