Site with extjs isn't loaded. Kaspersky main.js throws error

[DarkElfikus]

Open site with extjs (site that I opened required credentials, but you can register trial on www.actitime.com). Kaspersky main.js fails on "if (key.toLowerCase() === "headers")" with TypeError: Cannot read properties of undefined (reading 'toLowerCase')

Probably, problem in additional "hidden" key when `for (... in ...)` get `i` from `entries`. On screenshot the array has 5 items, by `i` get `remove` value from somewhere. Probably, it was added by extjs in

Ext.applyIf(Array.prototype, {
    indexOf: function(c) {
        for (var b = 0, a = this.length; b < a; b++) {
            if (this[b] == c) {
                return b
            }
        }
        return -1
    },
    remove: function(b) {
        var a = this.indexOf(b);
        if (a != -1) {
            this.splice(a, 1)
        }
        return this
    }
});

So, looks like kaspersky 'main.js' script should handle such situations correctly.

Hello @DarkElfikus, 

Welcome!

1. That's cause it does:                                          
2. IF (your) goal is to get Community members to test a problem for (you) start with this please: Read before you create a new topic! by Danila T.  - include the full version & build of the Windows computer, (your) Kaspersky software version & the browsers, name & version (you've) tested the issue in?
3. What happens IF, in Network settings -> Inject script into web traffic to interact with web pages is *unchecked* & OR, if actitime domain is added as a trusted address? 

Thank you🙏

1. I installed the extension but I can't enable or disable "Anti Banner" or anything else there, because options not accessible in free version. The issue was reproduced after removing the extension.
2. Versions
   1. Windows - MS Windows 11 Pro x64 Build 22631
   2. Kaspersky - Free Version 21.19.7.527(a)
   3. Browsers - Chrome (131.0.6778.70), Edge (131.0.2903.51), Firefox (133.0)

   I checked this only with Chrome. Here is a strange thing. In most attempts the problem stops reproducing (the script isn't called and site working) after applying any of the settings but I had to restart browser to see the effect. But after several installations and deletions of browser extension there weren't any effect of changing the settings you mentioned.
