I am searching for what the "Don't load tabs until selected" options promises in Firefox.
As it seems the option works fine when Firefox is set to load the tabs from the last session upon start. Only the foreground tab is loaded and all other tabs are only loaded when I select them. For all other cases background tabs are always loaded straight away. (Scenarios tested: load diverted tabs in background, open multiple bookmarks my middle-click on a folder)
What I want is a setting, plug-in or greasemonkey script that prevents every tab that is opened in the background from loading.
OR even better: if there is only one backgrund tab opened -> load it, if there are multiple tabs opened in background within a short amount of time -> prevent loading.
My question is just slightly related to this one: Prevent auto-loading of tabs in Firefox when starting browser They search for something that works at start, but this is already achieved by the "Don't load tabs until selected" option.
None of the below solutions (provided in 2016) work anymore. Is there currently (in the year 2022) any way to "prevent background tabs from loading in Firefox" ?
