User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:17.0) Gecko/20100101 Firefox/17.0 (Beta/Release) Build ID: 20131022185104 Steps to reproduce: Set up Firefox Sync on a Firefox 25 and a Firefox 17. Then there is one addon (the latest version vimperator) which is not compatible for Firefox 17. Actual results: After syncing, the incompatible version was installed on Firefox 17. Expected results: For Firefox 17, an old version should be installed to keep them compatible.

Only desktop Sync supports add-on sync, so moving to Backend. I'm pretty sure this is a WONTFIX, though. Add-ons are increasingly version-agnostic, and we very much want to discourage people from using outdated, less secure, slower versions of Firefox -- the current ESR release is Firefox 24, so there's no way we want to make it more likely that you'll stick with 17.

Actually when I opened this ticket, the ESR is 17.0.x. Basically what I am talking about is mainly ESR version and the latest version. Some addons may drop the support of an older version -- the current ESR version may also be dropped. So syncing between the current ESR version and the latest version can be a problem.
Thom has a good analysis of how we decide which add-on version to install in bug 1393929, comment 4. The TL;DR is that we trust the add-on's compatibility info on AMO, and this should be less of an issue in the WebExtensions world.
