Android Severe page loading issues on Google, X, Facebook, and Cloudflare verification sites (Last 3 days)

'''Android Severe page loading issues on Google, X, Facebook, and Cloudflare verification sites (Last 3 days)''' Dear Firefox Engineering and Support Team,I am writing to report a critical browsing issue that started occurring about 3 days ago. This issue severely impacts page loading on major platforms and makes browsing nearly impossible. 1. My Device Environment:OS: Android 12Affected Versions: Firefox Beta (Primary), Firefox Nightly, and Firefox Stable (All are updated to the latest versions). 2. Detailed Description of the Issues:Google.com: When searching for keywords, the browser frequently encounters a "Page failed to load" / "Unable to connect" error. If the search page manages to load, switching to the "Images" tab instantly triggers the page load error again. Social Media: The exact same page loading failure happens frequently when trying to access x.com (Twitter) and facebook.com. Cloudflare Captcha Verification: On websites requiring Cloudflare verification via Google search clicks, the browser immediately crashes or kicks me out of the page right after clicking. I have to attempt accessing the link repeatedly (several times) to finally get through. Desktop Mode Trigger: On all tested Firefox versions, forcing the view from "Mobile mode" to "Desktop mode" immediately and consistently triggers the page loading error. 3. Troubleshooting Steps I Have Already Taken (with NO success): Cleared all browser cookies and cache. Completely uninstalled and re-installed all Firefox versions (Stable, Beta, Nightly). Removed all extensions and tested on a completely fresh, vanilla installation with zero add-ons installed, but the bugs still persist. Since this issue happens across all Firefox release channels (Stable/Beta/Nightly) even on fresh installations, I suspect it might be related to network stack rendering, user-agent handling, or an incompatibility introduced in a very recent upstream update affecting Android 12. I would highly appreciate your investigation and guidance on how to resolve this. Thank you for your time and continuous dedication to improving Firefox. Best regards, M_Ng
