I’m facing a strange issue after the recent Firefox update. Whenever I try to install or update Firefox to the latest version, the process stops midway and a small popup appears related to a “[https://e-challan.pk/ challan notification]” from a website I recently visited. After this popup appears: The installation freezes Automatic updates fail Firefox sometimes restarts but remains on the old version No error code is shown, just the interrupted update process I have already tried: Clearing cache & cookies Restarting Firefox Safe Mode Reinstalling Firefox manually Checking firewall/antivirus settings But the problem still occurs. I want to confirm: Is any website notification (like a challan reminder or traffic-alert site) capable of interrupting Firefox updates? Does Firefox block updates if a previous session was not closed properly due to such popups? What is the correct method to force a clean update without affecting my browsing data? Please guide me on how to fix this issue. Thank you!
