If I search for an page visited I sometimes need to check several similar history entries. Default of Firefox is, that every time I right-click and select open in new tab, the new tab opens and the history-window disapears. For bookmarks I found out, that you can tweak in about:config the browser.tabs.loadBookmarksInBackground and browser.tabs.loadBookmarksInTabs to true, so that firefox opens bookmarks in a new tab and in the background.

I thought I found the same for my history problem with browser.tabs.loadDivertedInBackground However, now it opens any "diverted" new tab in a background tab, but I only want it for new tabs out of the history window and not e.g. when clicking on a link in a pdf. Then I want the clicked link to pop up directly.

I have "browser.search.context.loadinbackground" set to true on my Firefox (version 86.0b7). In the Library->History menu, as well as the History sidebar, I can Middle-Click to have the URL open in the background.

For completeness, I also have these set to "true":


Hope that helps you. Regards, Andi

  • you are my todays hero. setting browser.search.context.loadinbackground to true does indeed work as intended. (open tabs via history in the background, but tabs from external programms in the front)! Feb 10, 2021 at 13:19
