I can't find anybody else having these issues. I installed the Chrome beta a while back, and it's been updating itself since, but I need to finally get extensions working - I need my Adblock (Digg is completely unbearable without it). I read about the method to enable it weeks ago, just install the dev version - agree to the EULA and download. I did that, and overwrote the existing copy of Chrome. I didn't remove any other files. I still can't install extensions using the bookmarklet - it enables the install button, but I receive 'Extensions are not enabled' immediately after the download tries to start. The other thing is, the dev version is supposed to include the bookmark manager. That's also nowhere to be seen. Chrome says I'm running version 22.214.171.124 and that it's up to date. Any ideas? Do I have to completely remove Chrome before installing the dev version (i.e. everything I've built up in my Chrome profile to this point in Application Support)? Any input is appreciated!
