in preferences, on the "tabs" section, the bottom box [when I open a new tab, switch to it immediately] is unchecked. in fact, I've never had it checked.

firefox just started opening tabs in the foreground randomly (it does it 75% of the time, not all the time, and there is no apparent pattern to when it does what it does) once when I started it up after it crashed for the 100,000,000,000,000,000,000th time.

have tried closing and restarting firefox, and restarting my mac, but it keeps on happening. why is it doing this and how do I stop it?

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the add-ons is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).

  • Don't make any changes on the Safe mode start window.

See:

If it does work in Safe-mode then disable all extensions and then try to find which is causing it by enabling one at a time until the problem reappears.

  • Use "Disable all add-ons" on the Safe mode start window to disable all extensions.
  • Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")

thank you for your reply. the only extension that I'd added was adblock plus, yet there were a slew of "divx" extensions that wouldn't let me disable or uninstall them. (I'm not a "divx" user, so am not sure how I came to get these beasts). finally dug around with my finder and trashed all sort of odds and ends in the library, etc, before they stopped showing up as both extensions and plug-ins.

so far, so good. many thanks for the 101. I surely needed it.
