TestComplete15.63 is unable to recognize a range of standard html controls in Object Browser

Hi,

it seems that TestComplete15.63 is unable to recognize a range of standard html controls such as html textbox, pushbutton etc, please also see screenshot attached, compared with previous version TC15.49 where the controls are shown in Object Browser.

As FF115.4esr is officially supported by TC15.63, i suppose there might be something wrong in the configuration on my side, but i just tried all options of following instructions and no success:

Considerations for Web Testing | TestComplete Documentation (smartbear.com)

Preparing Firefox for Web Testing | TestComplete Documentation (smartbear.com)

any help would be much appreciated.

Thank you.
