Disturbing news to me. I've seen more than one post here today: [webmasterworld.com...] and [webmasterworld.com...] mentioning that when people update their Adobe Flash Player at Adobe's Flash Update site: [get.adobe.com...] that there is a checkbox which is checked off by default to install the Chrome Browser when you update your Flash Player and set Chrome as your Default Browser.
By coincidence I had visited the site today to check the latest version to see if I needed to update. I did see an (unchecked) offer for a Trial of Adobe Lightshop, but no mention of Chrome.
My curiosity is piqued because I'm not seeing this default selected Chrome bundle. Is it for Windows only? (I'm on Mac) Or do I not see it because I have Flash disabled (even on Adobe's site) by default. Nosy people want to know. Have Google and Adobe got an agreement?
Reading more information gives a somewhat altered view and though incomplete, at least it seems there is some reasoning behind the dual upgrade, though "Default Browser" seems an unnecessary territory grab to resolve a general aggravation.
There was a time when Flash did not work in the Chrome Browser and because using it in any browser had always been a pain because of the "LSO" problem of locally stored objects. Flash cookies were not regular .txt cookies stored in your browser's Cookies files, they were hard to find little .swf files and because browsers used Flash as a plugin it had to be activated for sites to read those LSOs. Beginning in 2011, Google changed the way Flash worked in their browser, partly to defend users but also to give users a way to keep Adobe Flash updated automatically. Flash became an integrated part of the Chrome browser. If you have ever tried to use Adobe's abominable Installers you can see why this could be seen as a user benefit. Apparently Google's integration of Flash allowed the browser to "sandbox" Flash until it installed a new version when Flash security issues were known. Techcrunch wrote it back then: [techcrunch.com...]
Other browsers continue to use Flash as a plugin and it continues to cause issues because of the local file storage. Adobe has some information too, (not dated) that gives some information: [helpx.adobe.com...]
Since it looks like Chrome is the only major desktop browser with Flash integrated and auto-updated, it is mutually beneficial for Chrome and Adobe to cross promote.
