Set new tab url with master_preferences file

[Artyom Pranovich]

Hey everyone,

Assuming I have my custom Chromium build, I'd like to change New Tab page url that opens whenever new tab is opened.
I know that it's possible and easy to do with extension, but is there any way achieve that using master_preferences file?

I though that these properties below should be self-explanatory and do what I'm asking here.

"homepage" : "http://myawesomepage.com",
"homepage_is_newtabpage" : true,

But it doesn't seem that it works. After I applied these changes, Chromium still opens default new tab page, and besides that even Home Page button doesn't get user to http://myawesomepage.com.

Any ideas why it doesn't work, and probably are there any other ways achieve that w/o installing extension that overrides new tab?

Chromium version - 70.0.3501.0 (Developer Build) (32-bit)

Thanks.
