Let me preface this question by saying: It's crazy. I know it is. But the requirement is not mine, it's someone else's, and I'm trying to honor it.
I need to install a months-out-of-date version of Google Chrome so I can run repeated tests against it. But it's proving to be surprisingly difficult to turn Chrome updates off.
I did the trick of disabling the "Google Update" plugin in chrome://plugins. After that, I uninstalled Chrome and installed the old version. I double-checked that the version was the old version and that updating was non-functional ("error 3"). I didn't even see "Google Update" listed in chrome://plugins at all after this. So I thought I was good.
Then just now, I fired up Chrome to look at it again, and it was back to the newest version!
Is there something I overlooked? Are they doing some kind of black magic here?
