I have recently upgraded to Windows 10 and the ‘Open in browser’ command is missing when you right click on the code. I reloaded Sublime Text 2 and have also loaded Sublime Text 3 but it is still missing. On my Windows XP machine the option is still there. Is there a function on Windows 10 which facilitates this operation?

I think that “open in browser” comes from a package: https://packagecontrol.io/packages/SideBarEnhancements

Do you have the same packages on your two computers ?
