--disable-web-security doesn't work in the last update

[Vus]

I updated Vivaldi recently to v 5.5.2805.42 and JavaScript in local files stopped working even with --disable-web-security switch. I changed NOTHING in the command line, which I always used to start the browser, so it is the new version that caused my JavaScript developing process to stop completely.

There is no menu to enable/disable separate permissions for local files.

Now I have to rollback to the previous version.

Please! I do not want to install and run a whole webserver just to be able to test one HTML document. I am not making a website, but testing the software REST interface.

@Vus Which errors are shown in Developer Tools Console (Ctrl Shift J)?

Hi, please don´t rollback to an older version with the same profile, it possible break it.
I cant find this flag in chrome://flags anymore, even when I enable old Chromium 105 and 104 flags.
It seams the Chromium developer have removed it, nothing the Vivaldi devs can do about.

Cheers, mib

Try chrome://settings and search for javascript.

@Vus I remember command switch --allow-file-access-from-files but i do not know if that was removed.

@Vus said in --disable-web-security doesn't work in the last update:

JavaScript in local files stopped working

Javascript and even REST in local files works fine here, without any flag set.

Hi, if I start in a terminal I get the error:

Web security may only be disabled if '--user-data-dir' is also specified with a non-default value.

This is not my area, maybe it will help you anyway.
