Firefox 66: Scroll Anchoring fixes scroll position jumps during loading

[harlan4096]

Mozilla implemented a feature called Scroll Anchoring in Firefox Nightly recently that fixes a very annoying scrolling related issue.

Here is the issue: open any site with a good number of images or other content and quite a bit of text. Scroll down while the page still loads and stay on a fixed position. The loading of content such as images changes the position on the page.

I experience the issue regularly, for instance when starting to read a long article or text on a site without waiting for all content to be loaded on it. The loading of images and other content that takes up space may move the visible part of the page so that I have to scroll again to go back to the position I was at.

Images, media, and other content on the page may not be loaded immediately. It depends on various factors such as size of files or the number of images on the page.

Tip: check out our Firefox download guide to find out how to download Firefox Nightly. We suggest that youuse different profiles for Firefox.
