Hiding the toolbar while scrolling causes the webpage to load incompletely.Firefox Android 150.3 — "Hide toolbar when scrolling" causes incomplete page loading (Post fully rewritten)

I haven't received a reply for a long time, so I've completely rewritten the entire content of my post. Below is the updated version： Device： Firefox for Android, version 150.3 Issue Description： When "Hide toolbar when scrolling" is enabled, webpages (especially search result pages) fail to load completely — content cuts off before reaching the bottom. Disabling this option resolves the issue immediately. Steps to Reproduce： 1. Go to Settings → enable "Hide toolbar when scrolling" 2. Open any search engine and search for a keyword (e.g., "bbc news") 3. Scroll down to the bottom of the search results page Expected Result： The page loads completely to the bottom Actual Result： The page stops loading prematurely; bottom content is missing Additional Notes： I have a screen recording demonstrating this issue, but the forum does not support video uploads. I'm happy to share a video link or send it via email if needed. Also, it would be great if the feedback page could support Chinese — I currently have to rely on translation tools to submit reports, which adds extra friction. Looking forward to your response. Thank you!
