How can I fix my LinkedIn screen from cutting off half of Home screen in Firefox but not in other browsers

The fact that the problem is only happening in Firefox suggests that a setting, extension, or temporary file is causing the display to break on that specific site. Reset Your Page Zoom Go to the LinkedIn home page in Firefox. Hold down the Ctrl key and press 0 (the number zero). This will reset the page to 100% zoom, which often fixes layout issues. Disable Enhanced Tracking Protection Go to the LinkedIn home page. Look for a shield icon on the left side of the address bar. Click the shield icon, then click the toggle switch at the top of the pop-up to turn off protection for LinkedIn. The shield icon will get a line through it, and the page will reload. Clear Cookies and Site Data for LinkedIn While on LinkedIn, click the lock icon at the left side of the address bar, click "Clear cookies and site data...". A small window will pop up asking for confirmation. Click "Clear." You will be signed out of LinkedIn.
