Ok. 2206 and 2250 in my setup work well vanilla. With addons, depending on the addons, they crash often, but mostly with youtube. In both cases I was able to come up with addon/settings combinations that work in my system, without youtube crashing, and with most top-heavy scripted pages (FB, gmail, etc) loading with no issues. But again, it is hit and miss, depending on the characteristics of different setups. The main issues is, again, youtube.
I gave Humming Owl's 9.5 version another try, and it runs well and stable. Nether his version, nor 2206 and 2250 by ArticFoxie are DRM enabled. I do swear I watched part of a couple of Netflix movies in 2250 in the first run, though, although I can't replicate now. I must have been dreaming.
Now, if the directory structure in Humming Owl's 9.5 is adapted to replicate the one provided by ArticFoxie, it is possible to run the 360Loader ArticFozie provided, with (I think) the settings given in his 360Loader.ini. With a vanilla default profile (at least) it is possible to simply change the content of chrome/application, shifting versions with no problem (at least in the limited testing I have done).
I am now testing whether or not the registry settings in 360Loader.ini are really needed. It seems to me that they are unnecessary. 360Chrome writes the entries alone, with "wrong" data (bad language definitions and other settings, such as fixed default search engine, etc), so ArticFoxie's reg files in 360Loader.ini are necessary.
PS: no need to apologize, ArticFoxie. Thanks for your efforts, and the same to Humming Owl.
