Cannot communicate with the browser - firefox

[Anirudh_Kamboj]

I am getting this pop up while I am indicating the browser for selecting the tab. -
“Cannot access the indicated browser window. Note: If using Incognito Mode, please enable the UiPath extension for Incognito Mode. If using a browser running instances with different user profiles, please install and enable the v23.10 UiPath extension or a more recent version.”
This Error is coming after installing the extension for firefox.

This is the version I am getting after trying to install it many times and I have also enabled the two options underneath it still it is not working.
