Paginated posts : how to check opened "pages" in navigator tabs and reach them ?

Hi,

Problem
When the user reads a paginated post he often open several “pages”.
This occurs particularly when there is a “page” (I name it often a section to avoid misunderstanding) used for refs, bibliography, indexes for long documents.

Then the problem is the way to manage a Table of Content for paginated posts able to not re-open an already opened tab.

Existing capabilities and limitations
Most of time this is possible with extensions (the API for Chrome, FireFox etc.) and not allowed for any other script of a tab. This is normal because of security problems.

Nevertheless, it should exist a solution when the request to access to url of a tab is issued : a like “windows.tabs… .url” is asked by the parent tab (opener). Commonly the access to url property of tabs needs to be declared in a extension manifest file.

Do anybody has an information or piece of code.
I would with a TOC (which holds paginated posts and gives the full TOC of a paginated post) to manage the access to several tabs opened for the same post, this without re-opening an already opened “page (section)”.

Best regards

Trebly
