For many years, I've been using the great feature "zoom" to view websites, it was simply amazing that firefox would remember the zoom level of each individual site, so when I re-visited the sites would instantly appear great on my monitor. Unfortunately, this worked up until firefox 54, once I upgraded to firefox 56, the zoom feature no longer remembers each websites zoom level :( now I have to manually re-zoom each site over and over again. I know that there are plugins out there to do simulate this feature, but I don't trust 3rd-party plugins and I would prefer to have this feature native in firefox like before. Thank you. PS: I'm using Fedora 26 Linux, the affected package is: firefox-56.0-2.fc26.x86_64 and browser.zoom.siteSpecific is set to true (the default).
