Vimium does not work in Strict Site Isolation mode

[wichtounet]

Hi,

I'm not sure this is really a bug, but I've tried to use Strict Site Isolation on Vivaldi (Chromium engine) and it does not work.

For instance, t opens correctly the input search box but I cannot write inside.

I don't know how Strict Site Isolation mode works, so maybe this is completely expected, I just wanted to report it in case you didn't know ;)

Thanks

Baptiste

System

• Vivaldi | 1.13.1008.40 (Stable channel) (64-bit)
• Linux
• Vimium 1.62.4

Cannot reproduce in Chrome. Anybody else?

@wichtounet Are there any error messages in the console?

@smblott-github The Console in the web tools ? Nothing here related to vimium.

I've reproduced this on Vivaldi with the flag #enable-site-per-process enabled, and I think it's a bug of Vivaldi and there's few things we can do about it.

In fact, #enable-site-per-process is a highly experimental feature of Chrome (also Chromium-kind browsers) for a long time, and there're some bugs caused by it on old versions of browsers. For example, Chrome whose version <= 48 will break Vimium if only the flag is enabled, because the Window.postMessage API is implemented bugly.

So I suggest that you disable the feature - Chromium browsers are usually safe enough with default settings.

@gdh1995 Thanks for the investigation :)

I've already disabled the feature, I was mostly testing it but I don't really mind not having it.

If it's a problem related to some versions of browsers, it's indeed not your problem 👍
