GM.openInTab/GM_openInTab options not working.

[PrakashChetan]

I am trying to open some url in a pinned tab using GM.openInTab, but firemonkey is opening url as a normal tab. Script is working properly in violentmonkey though. So Naturally I tried other options like container and incognito but same result not opening links in incognito tab or a container.

GM.openInTab(url, {
  pinned: true,
});

pinned in GM.openInTab is non-standard and supported by Violentmonkey, but not by Tampermonkey or Greasemonkey.

In FireMonkey, it takes the value of the "same as opener tab".

It can be looked into in future upgrades.

Yeah, this feature would be awesome. Kindly look into it.

As I preparing v3.0 for release, I have been looking int the issue.

Conceptually, a userscript is meant to run in the context of a single tab. Having pinned ability would mean a userscript can potentially open a tab and hide it in a pinned corner which might not be seen by the user if they have many open and pinned tabs.
The feature would be open to abuse e.g. opening many advertisement tabs, especially since Firefox reloads pinned tabs on restart, even if they are not active.
Why would a userscript need to open a tab that is hidden from the user?

Yeah I agree that this feature could be misused if user just use some random script from internet, but it can be said for any userscripts in general. Users are expected to have look through userscripts.

I find this feature useful as it will allow me to directly open pages from search engine to next tab instead of going to context menu and selecting next tab or weird middle click. Also it will allow user to open automatically open url from certain from to automatically open in some container/incognito. And many more QoL additions.

I am guessing that you are making your own scripts and your use-case would be specific to your need.
However, most users use userscripts that are written by others and most don’t have the expertise to check the userscript content.

In case it helps, FireMonkey maintains the original tab state i.e. if the tab is a pinned tab, GM.openInTab will open a new pinned tab.

[PrakashChetan]

All I am saying is even allowing running userscripts is enough for malicious behavior, opening url in some other tab or in tab in other container can't be worse.

Let's see if there is a popular demand for the feature.
