disable use of Pinned Tabs
Hi all, my daughter has found out that with Pinned Tabs she can work around the site-specific time limits I have set inside a parental control product (on windows10).
Normally the parental control just closes tabs that display a forbidden or over-used web URL. But as Pinned Tabs have no close button it seems to fail. It only reports "time is over".
Is there a way to disable Pinned Tabs ? In about:config maybe?
Thanks and best regards Daniel

Hi Daniel, I don't think there is a setting to disable pinning tabs.
An extension could detect when a tab is pinned and revert it to a normal tab, but your daughter probably would figure that one out, too...
You can give a pinned tab a close button with code in userChrome.css if that is all you need.
Add code to the userChrome.css file below the default @namespace line.
@namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"); /* only needed once */
.tabbrowser-tab .tab-close-button[pinned] {display:-moz-inline-box!important}
See:

- https://www.userchrome.org/how-create-userchrome-css.html
In Firefox 69 and later you need to set this pref to true on the about:config page to enable userChrome.css and userContent.css in the chrome folder.
- toolkit.legacyUserProfileCustomizations.stylesheets = true

Thanks to cor-el for pointing me to userChrome.org !
This page contained the clue: "Hiding unwanted menu items" - works also in context menus!
Last problem: how to restrict access to the about:config page?
(have Firefox setting managed by an "organization" == me ? )
Best regards Daniel
Keep in mind that you can also pin a tab via the three dot page actions menu. You can even add a pin icon to the location bar via the right-click context menu and there are extensions that allow to pin a tab.
You can use a policy to disable access to about:config.
