When I scroll down a page and click some link there, and later go back to the orignal page, the page is displayed from the beginning. For example, I go to https://en.wikipedia.org/wiki/Firefox, scroll down to "See also", click "Mozilla Prism" link there, and then the Firefox' back button; I land at the beginning of the Firefox article instead of the place I was last, i.e. around "See also". Reading long articles and navigating back and forth to references is currently not possible, unless I open every link in new tab/window without leaving the original page. Chrome and Vivaldi don't exhibit such behavior, going back in history brings me to the vertical scroll position of where I left. I also *think* in old Firefox the behavior was consistent with Chrome. BTW, navigation with URL fragment also doesn't work. If you enter https://en.wikipedia.org/wiki/Firefox#See_also into new tab, you are correctly moved to "See also" section. From there, click "XUL Runner" and going back moves you to the top of the Firefox page, where you never were... Refreshing the page doesn't change that. BUT forced refreshing (Shift+Ctrl+R) with cache skipped moves you correctly to "See also" section again. Linux Mint 18.2, Firefox 60.0.2 from Mint repos. I don't see such behavior under Windows (same version, official build), where it works as under Chrome. Is it some setting, or a bug? (Firefox? Mint? Ubuntu? other?)
