How do I stop yahoo from re-setting as my default homepage?

已張貼

I am operating OSX 10.8.5 and Firefox 26

Recently (without having installed new software or extensions) my homepage setting in firefox default to yahoo. Yahoo also showed up as one of my search engines w/o me having installed it. I deleted it and everything was fine for a while. But now instead of showing my windows and tabs from last time, it just shows yahoo instead.

This is very annoying, because I keep loosing all my pinned tabs. None of the solution discussed above are helpful and the problem persists even in the safe mode.

Below is the troubleshooting info from "Firefox about:support"

Is there any chance that you installed a customized version of Firefox optimized for Yahoo? See http://downloads.yahoo.com/firefox/

Yahoo-customized versions of Firefox are mentioned in the article Remove a toolbar that has taken over your Firefox search or home page. If you have one (they're offered for both Windows and Mac) you'll have to replace it the "official" version of Mozilla Firefox.

In any case, you could trash Firefox (remove it from your desktop/dock/Applications folder) and then reinstall Mozilla Firefox by downloading a fresh copy from mozilla.org - see How to download and install Firefox on Mac. Your Firefox user profile is stored in a separate location - see the Profiles article - so your bookmarks, passwords, and other user data should be preserved.

You could also try a Firefox Reset - see Refresh Firefox - reset add-ons and settings

First, to manually restore your previous session until this is solved, you can use the History menu > Restore Previous Session.

Second, how long does the change last in the user interface? By that, I mean, if you select "When Firefox starts: Show my windows and tabs from last time" and OK the change:

  • If you go back into the Preferences dialog, does it show your changed setting?
  • Does it work for even one startup?
  • The setting lasts but actually it is ignored?

to jscher2000:

a) no idea whether it kept showing in the preference dialogue box after I restarted Firefox or the entire system

b) It has worked for several start-ups. At first with no problem at all. After it happened the third time, I had to restore tabs, by clicking on the Firefox screen "Restore previous session".

c) not sure what you mean by "The setting lasts but actually it is ignored? "

Hello,

Try Firefox Safe Mode to see if the problem goes away. Firefox Safe Mode is a troubleshooting mode that turns off some settings and disables most add-ons (extensions and themes).

(If you're using an added theme, switch to the Default theme.)

If Firefox is open, you can restart in Firefox Safe Mode from the Help menu by clicking on the Restart with Add-ons Disabled... menu item:
FirefoxSafeMode

If Firefox is not running, you can start Firefox in Safe Mode as follows:

  • On Windows: Hold the Shift key when you open the Firefox desktop or Start menu shortcut.
  • On Mac: Hold the option key while starting Firefox.
  • On Linux: Quit Firefox, go to your Terminal and run firefox -safe-mode
    (you may need to specify the Firefox installation path e.g. /usr/lib/firefox)

Once you get the pop-up, just select "'Start in Safe Mode" Safe Mode Fx 15 - Win

If the issue is not present in Firefox Safe Mode, your problem is probably caused by an extension, and you need to figure out which one. Please follow the Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems article to find the cause.

To exit Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.

When you figure out what's causing your issues, please let us know. It might help others with the same problem.

Thank you.

to Diego Victor:

tried that yesterday and the problem persisted.

Right now Firefox is behaving O.K. again, i.e. my pinned tabs remain and Firefox shows all the windows and tabs from the last time.

However, in the past it has defaulted to yahoo after some time for no apparent reason.

If you do not keep changes after a restart or otherwise have problems with preferences, see:

Hi cor-el, Checking the Mozilla Profile was quite startling: I do have a Mozilla folder, but it is empty. It contains only one other folder "Extensions", which is empty, too. Searching for "prefs" delivers no results. Searching for "Mozilla" delivers no results. I'm confused.

At the moment Firefox works OK, but just noticed that Yahoo appeared as my homepage in the preference settings (Just changed it back to Firefox). This is weird, because I do not use Yahoo whatsoever.
