Hello: I use 1P on my Mac and sync via Dropbox ... had to install Windows so I got the 1P version of Windows ... but every time I install the Chrome extension on the Windows version of Chrome two things happen: (1) the extension correctly installs and works; but (2) the extension also gets included on my Mac version of Chrome. But the Mac version results in a message saying that I've installed an outdated version of the extension. And if I delete the new Mac extension, it also results in the Windows extension getting deleted -- even if I close the Windows version of Chrome and then delete the new Mac extension. Maybe this has something to do with my Google gmail syncing, but before I start messing up my syncing I wanted to benefit from the group wisdom. Thanks.
