This existed (Firefox's GCLI)[0], but was quite recently removed.[1] > upgrade Conkeror to not require XUL That's not strictly necessary. Firefox still uses XUL and will probably continue to do so, for a long time. You can still build applications that rely on XUL and run them, for instance with "firefox -app application.ini". Both Thunderbird and Zotero have upgraded to rely on FF60. From a UI toolkit/architectural point of view, Conkeror doesn't really need anything more than Firefox, even if it's arranged rather differently, so as long as XUL in mozilla's codebase can support Firefox, it could also support Conkeror. The only™ issue is that while previously Firefox didn't care much about breaking third-party applications, when changing XUL, now (post FF57), they don't care at all, with the very partial exception of issues affecting Thunderbird. (I'm not assigning blame — I understand the problems facing Mozilla.) Hence all of Conkeror's developers have presumably decided to give up. However, I'm not sure whether keeping up with Firefox's changes might not be easier than migrating to, say, Electron... > add Gecko to Emacs Emacs can already embed WebKit and it's very rarely used.
