Will I be stuck on the Chrome developer version forever?
Solution 1:
And does that mean, that I'm with the dev version stuck forever until Google decides to resolve this? I mean how am I supposed to downgrade now that all my profile data seems to be "contaminated" with data fragments that show that I ran a developer version of Google Chrome?
You won't be able to use the profile data with a stable build till the stable build reaches the same version as the dev build. The stable builds are about 6 weeks behind the developer build.
