[ https://issues.jboss.org/browse/JBIDE-18054?page=com.atlassian.jira.plugi... ] Denis Golovin commented on JBIDE-18054: --------------------------------------- [~ibuziuk], you're right about xulrunner, I thought I had turned it off by excluding linux bundle from my development environment, but obviously JBT started from dev environment still took system xulrunner because I forgot to exclude xulrunner.initializer as well. This xulrunner.initializer sets system property to force xullrunner based browser and in my case system xulrunner was taken. Now I can see it works when I have both xulrunner linux bundle and xulrunner.initializer removed. Shouldn't we show sort of warning when html5 files are open with xulrunner based VPE of Visual Preview and have this explained in FAQ. To address my issue with xulrunner.initializer we can mention it in FAQ how to disable xulrunner.initialization in preferences or move it over to xulrunner feature (it requires to update xulrunner feature and release it again). -- This message was sent by Atlassian JIRA (v6.2.6#6264)
