I am working with the newest 64-bit version of Firefox on a 64-bit Windows 10 Pro system. When visiting https://www.olx.pl/opatow, the page appears for just two seconds before disappearing. Even after disabling all plugins in the Firefox web browser, the issue persists. A thorough inspection of the user folder revealed that removing only one specific file—C:\Users\User\AppData\Roaming\Mozilla\Firefox\Profiles\b4imxov8.default-release\storage\default\https+++www.olx.pl\ls\data.sqlite—restores normal display. However, upon re-entering the site, Firefox regenerates this file each time, which increases the risk of corruption. This setup is becoming familiar to me; I would like to configure it so that only this particular file is deleted every time the browser starts, preventing the need to manually remove it if the site fails to open. Would it be feasible to adjust Firefox so that each launch deletes just this one data.sqlite file?

I currently have several plugins installed. When uBlock Origin is active, should I consider installing another Adblock Plus plugin, or are these similar to antivirus solutions? Also, why does Firefox generate such a large number of folders—C:\Users\User\AppData\Roaming\Mozilla\Firefox\Profiles\b4imxov8.default-release\storage\to-be-removed? I am using a TOSHIBA HDWD110 hard drive. After years of use, Firefox has been slow to start. In the specified folders, over 15,000 files have accumulated, and deleting them improves performance instantly. Why does Firefox accumulate these unnecessary files?

What is your DNS configuration? Which antivirus or malware protection software are you currently employing?

DNS Servers ... are set to 10.1.1.1. Have you verified the DNS server with the ipconfig /all command in cmd? I'm not very familiar with the internet. I use Windows Defender, which is included in Windows 10.
