Download Chromium
You can test Chrome builds or Chromium builds. Chrome builds have the most infrastructure for analyzing crashes and reporting bugs. They also auto-update as new releases occur, which makes them a good choice for most uses. Chrome Canary is available for Windows and Mac and autoupdates daily. Other channels (dev and beta) are available.
Chromium builds do not auto-update, and do not have symbols. This makes them most useful for checking whether a claimed fix actually works. Use the following instructions to find builds:Easy Point and Click for latest build:Open up https://download-chromium.appspot.com
Easy Script to download and run latest Linux build:Not-as-easy steps:Head to https://commondatastorage.googleapis.com/chromium-browser-snapshots/
Choose your platform: Mac, Win, Linux, ChromiumOS
Pick the Chromium build number you'd like to use
The latest one is mentioned in the LAST_CHANGE file
Download the zip file containing Chromium
There is a binary executable within to run
Please file bugs as appropriate.
Downloading old builds of Chrome / ChromiumLet's say you want a build of Chrome 44 for debugging purposes. Google does not offer old builds as they do not have up-to-date security fixes.
However, you can get a build of Chromium 44.x which should mostly match the stable release. 
Look in https://googlechromereleases.blogspot.com/search/label/Stable%20updates for the last time '44.' was mentioned.
Loop up that version history ('44.0.2403.157') in the Position Lookup
In this case it returns a base position of '330231'. This is the commit of where the 44 release was branched, back in May 2015.*
Open the continuous builds archive
Click through on your platform (Linux/Mac/Win)
Paste '330231' into the filter field at the top and wait for all the results to XHR in. 
Eventually I get a perfect hit: https://commondatastorage.googleapis.com/chromium-browser-snapshots/index.html?prefix=Mac/330231/
Sometimes you may have to decrement the commit number until you find one.
Download and run!
* As this build was made at 44 branch point, it does not have any commits merged in while in beta. 
Typically that's OK, but if you need a true build of '44.0.2403.x' then you'll need to build Chromium from the 2403 branch. Some PortableApps/PortableChromium sites offer binaries like this, due to security concerns, the Chrome team does not recommend running them.
