Firefox always opens a new window with ad.yieldmanager

As soon as i click on an image or other views on a website firefox opens a new tab with adyieldmanager and i cant get rid of it.

hello, this sounds like a problem possibly caused by adware/malware on your pc. please go to ''firefox > addons > extensions'' & remove any suspicious entries (toolbars, things that you have not installed intentionally, don't know what purpose they serve, etc). also go to the windows control panel / programs and remove all toolbars or potentially unwanted software from there and run a full scan of your system with the security software that you have in place and different other tools like the [http://www.malwarebytes.org/products/malwarebytes_free free version of malwarebytes] & [http://www.bleepingcomputer.com/download/adwcleaner/ adwcleaner].

My Google preferences are set to show search results in a new window. However, when I do a Google search, it Firefox always opens 2 new windows with the (same) results. How can I fix this?

I did not change my Google settings. I always have had it set to open search results in a new window. Some time ago, it started opening up two windows that have identical url/content.

That issue can be caused by an extension that isn't working properly.
Start Firefox in [[Safe Mode]] to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance/Themes).

Firefox always opens a new window when i click the icon on my task bar...this is new and I would like it to say in the same window How?

I have a firefox icon on my task bar. Before this latest install, I would click the icon and Firefox would come up directly. Now it opens another firefox window. I don't want this. How can I change it back?

Click on the spotlight icon in the top right of your screen (looks like a magnifying glass), type
Terminal
and press 'return'.
In the window that opens up, paste or type this exactly into the window
killall Finder; killall Dock
(that's case sensitive) and press 'return'.
You'll notice the Dock disappear for a second or two then return, as do any open Finder windows.
Test using Finder as normal. Same problem?

I often launch Firefox from the command line or LaunchBar. How do I prevent Firefox from opening a new window with my homepage along with a separate window with the location I intended to open?

Firefox lately always opens a new window

Whenever I click a link in firefox, whether I option-click it or right-click it and choose "Open in new Tab." Firefox lately always opens a new window, not a tab. For the life of me, I cannot get it to open a page in a new tab.
There was a time when I had one window open, and every time I would choose to create a new tab, it would create it in that window instead of the window I was currently in, but I have since closed that window, and now I cannot get a link to open in a new tab no matter what I do.
I have tried both selecting and deselecting "Open new windows in a new tab instead" In Firefox preferences, restarting Firefox in "Safe" mode, etc. to no avail.
How do I fix this?

There are other settings in about:config that might be causing that effect.
<pre>browser.link.open_newwindow
3 = divert new window to a new tab (default) (checked*)
2 = allow link to open a new window (unchecked*)
1 = force new window into same tab
* First checkbox in Options > Tabs (on Mac, Preferences > Tabs)
browser.link.open_newwindow.restriction
0 = open_newwindow preference honored for all new windows
2 = open_newwindow preference honored for all new windows except script windows with features (default)
1 = open_newwindow preference ignored completely (same effect as open_newwindow=2)
browser.link.open_newwindow.override.external
-1 = open_newwindow applies to external links (default)
3 = open external links in a new tab
2 = open external links in a new window
1 = open external links in active tab </pre>

Is there a way to open a new window with one site when the home setting on Firefox has multiple websites?

While working in Firefox is there a way to open a new window with one site when the home setting on Firefox has multiple websites?

I guess I'm not explaining myself fully. I have a home page designation in firefox preferences that starts firefox up with 5 sites. that pretty fills up my screen with tabs.
At some point I want to initiate another WINDOW in firefox (NOT a tab). I would like to be able to open up a window that ONLY has ONE tab, or as if there were only one site designated as the home page. This gives me a workspace that has my most useful sites available in tabs in one window, and also another WINDOW that I can move around in and even create more tabs without messing up my primary set of TABS (in my primary window). I see how this might not be doable without doing what I do now, which is open up a new window, and then close tabs until the new window just has one tab for me to work from.

Do a malware check with some malware scanning programs on the Windows computer. 
You need to scan with all programs because each program detects different malware. 
Make sure that you update each program to get the latest version of their databases before doing a scan.

FF Less stable than IE. Numerous crashes, the latest quirk is that it will open a new window with a website already working on and NONE of the iterations of FF work. Have to reboot computer because can't even exit FF. Fix it or on to Chrome.

'''''"a new FF iteration"'''''
No such thing. All Firefox windows and tabs run in a single '''firefox.exe''' process, unlike IE which has a separate process for each window, or Chrome which opens a new process for each tab.
As far as the Firefox SafeMode, you can't open it when Firefox is running ''(unless you open a separate Profile purposely)'', if you try all you will get is another window in the "regular mode".
You're not going to be able to discover the cause of your problem if you're unwilling to follow established troubleshooting procedures, regardless of how intermittent the fault occurs. I wouldn't be surprised of you have an add-on installed which is causing that problem.
Another course of action would be to create a new Profile, which is like starting from scratch with a completely new Firefox installation.

How can I open a new window with the same website like the one I have open?

In safari I can open a new window with the same website like the one I have open, that makes it easy continuing to navigate on a website and to go back to the original website

Hello Andieas
Why open a new window for fast browsing??
Open new tabs.
Just right click on what you want to open and click "Open in new Tab"
It is easy and doesn't consume memory from your computer as well as easy to navigate.

First link always opens a new window

I'm using Tomcat 3.2.3 and I have been unable to determine why the first link always opens a new window. From that point on, each hyperlink displays the page in the same window, as they should.
For example, my index.jsp page has a hyper link to the logon.jsp page. The logon.jsp page always comes up in a new window - even though the achor <a> tag is not setting any 'target'. It also doesn't matter if the first page is index.htm
I don't know if this is relevant, but Tomcat is running inside of Apache using the mod_jserv module. (at least I think it is.. I'm not sure how to tell... I followed the instructions at the Tomcat site and everything seems to load fine)
Thanks for any help....
E-

try by explicitly setting the target of the form to the same window.
I think it should work.

Firefox opens a new window with sites I never visited and don't want, I can not close these tabs or open another tab from them.

I open a new window and two sites appear, One I had never heard of till now. Digg. I can't open a new tab from these tabs, there is never an x on the tab and close all other tabs does not get rid of them.

Links that open a new window with javascript:void(null); do not work in 3.1

I've been noticing that any site I go to that opens content in a new window with "javascript:void(null);" will be ignored by Safari 3.1. The links work in Firefox and used to work in Safari as well. Any suggestions?

General rule of thumb in the Mac universe...
When Safari is updated most if not all third party add-ons break. That's because most don't play by the rules. The developer thinks they know how to do it better than Apple so they just do it their way. So the first rule of survival is to KNOW what you have installed on your machine at all times. Use something like textedit to create a document listing all of the third party stuff you have installed and religiously update the list. Second rule is to wait a few days before applying an update. Third rule is to visit your third party developers' sites and make sure their little gadget is compatible with the new Safari update.
Being aware of things will make life much easier for you in the long run.

Hope you can fix this or i will start using other browser.

Sometimes a problem with Firefox may be a result of malware installed on your computer, that you may not be aware of.
You can try some of the following programs to scan for malware:

* [http://support.kaspersky.com/faq/?qid=208283363 TDSSKiller - AntiRootkit Utility]
