Websites should obviously not be allowed to shrink or remove the scrollbar. The reason for this is because people like being able to scroll so that they can see the rest of the page.
Hear hear! There's a website I use that has made the scrollbar so tiny it might as well be invisible. It's certainly unusable. It is an absolutely pain and I don't understand the choice on their part, but if there was a way to prevent it browser side that would be amazing.
Yes, it's odd in about:preferences#accessibility in the "Keyboard navigation and scrolling" section there isn't an option called Prevent websites hiding or resizing the scrollbar
Microsoft Edge, under edge://settings/accessibility , has "Turn off custom scrollbars", which does this
It makes no sense. The scrollbar should be a part of the browser, not the website. The website can't make the URL bar smaller, so why the heck can it make the scrollbar smaller?????
