That means nothing.. what type of linux? what kind of customizations you did in your distro? WM? Based on which one? Drivers installed? And I’m not even going with your Firefox setup and what kind of addons you have.. such statement is expected from tech illiterates that see linux as a monolith thing or like MacOS where your OS will be identical to another for the most part, technically Linux is just a kernel per se. I use “linux” (mint cinnamon) with Firefox and ubo addon and that page loaded perfectly on thinkpad T470.
