Hi bjh_27, for opening links in the background, Firefox has different behaviors depending on how/why the new tab was opened. Could you check these settings:

(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button promising to be careful or accepting the risk.

(2) In the search box above the list, type or paste inback and pause while the list is filtered

(3) Double-click the following preferences to switch the value from false to true as desired:

• browser.tabs.loadInBackground - when you right-click > Open Link in New Tab, or Ctrl+click, or middle-click a link (default = true)

• browser.tabs.loadDivertedInBackground - when a link was coded to launch in a new window and Firefox switched it to a new tab instead (default = false)

• browser.tabs.loadBookmarksInBackground - when you direct a bookmark to a new tab (e.g., using right-click > Open in New Tab, or Ctrl+click, or middle-click a bookmark) (default = false)

Can you get it set the way you like?

Thanks for the reply! When I set browser.tabs.loadDivertedInBackground to true Firfox no longer automatically switches to the newly open tab when I click a link that causes a new tab to be opened.

Thanks.
