Opening multiple PDFs at once

Hii! I will try my best to help you! It sounds like the glitch is because Windows 11 sends file-open commands to Firefox faster than the browser can process them, causing one command to misfire as a blank browser signal. When you select and open multiple files simultaneously, Windows executes a rapid chain of requests. Don’t worry! You can resolve this issue. Change Firefox's External Link Behavior (Recommended) You can fix this by changing a hidden configuration rule in Firefox that tells the browser how to strictly manage external file requests sent by Windows 11. - Open Firefox, type about:config into the address bar, and press Enter. - Click the Accept the Risk and Continue warning button. - In the search preference box at the top, paste: browser.link.open_newwindow.override.externalThe preference is likely set to -1 by default. - Click the Pencil icon on the right side of the row to edit it. Change the number value to 3, then click the Checkmark to save it. Note: Setting this to 3 forces Windows to cleanly inject every single document link directly into a structured layout of new tabs, preventing the dropped file/blank tab loop. I hope this helps!
