STABLE version -- 5.0.1002.354

[hth4nh]

It’s time to update the version, for many people the webstore automatically redirects to a new webstore address https://chromewebstore.google.com/ where extensions are not installed in the browser, if you download them from there as an CRX and add them to the browser, you will receive a message about the browser version

In my cent browser, the latest version, a redirect was automatically enabled, in version 4 there is no redirect, in Supermium there is no redirect, on another computer with the same version and this account there is no redirect, although on this computer when there was a choice, I turned off the new store, I had an old address until yesterday
PS I managed to return the old website, deleted all Google cookies and logged into my account again, and the old website returned until it seemed to redirect to the new one

You can try my bookmarklet: https://gist.github.com/Hth4nh/b892045068a862629a1ab512a8f51eee
Triple-click the 4th line, then drag & drop it to your bookmark bar
When you need to install an extension, you just need to visit the extension's link (for example), then click the bookmarklet and you're done.
