Thread:VisualEditor/Feedback/Installed Latest VisualEditor (12/14/12) but still uses old editor?/reply

If the integration has worked correctly, and you have it switched on for your account (if that's how you've configured it for your wiki), on each of the namespaces that you've enabled it on, you should have a new tab labelled "VisualEditor" alongside the "Edit"/"Create" tab.

Assuming that you've installed it correctly, it not appearing is most likely an artefact of you using a browser that fails the current very-restrictive whitelist of what browsers are known to work in VisualEditor (the "big four" of Chrome/Firefox/Safari/Internet Explorer). Note in particular that forks of the big four browsers differ in the ways that we care about, so Iceweasel does not make it through the whitelist. Longer-term we will switch to using a blacklist for known-bad browsers, but we haven't had the opportunity to do this yet.
