Security alert on wrong page

Hi; I use Firefox on my phone and my laptop both. In my laptop (Lecoo pro 14, Ubuntu 26.04) in a domain range browser gives me '''security alarm''' and '''don't let me get in'''. This is normal but when I use other browser in my laptop or Firefox on my phone (s25 ultra) '''there is no problem at all''' and it works well! I tried all things. run commands like: ''sudo snap remove --purge firefox | sudo snap install firefox'', ''sudo apt search firefox/mozilla'' and than ''reinstall'' all installed packages and clear all caches on settings. But none of them worked. Thanks for your responsibility and making such great open-source app.
