Firefox opens up 2nd tab on startup

I am running firefox 3.6.8. I have had no problems until recently. When upon startup firefox will open my homepage plus another tab. the secon tab is always some type of advertisment page and usually contains pop-ups when I try to close the second tab. I have checked my settings and firefox is only set to open my homepage and nothing else. Please help it is annoying and I fear it may be some tyep of malware.

To see whether this is being caused by one of your add-ons, try these diagnostic measures.
First, make a backup of your computer for safekeeping. To back up Firefox, see [https://support.mozilla.com/en-US/kb/Backing+up+your+information Backing up your information].
Next, try starting Firefox in Firefox
[http://support.mozilla.com/kb/Safe+Mode Safe Mode]. Be careful not to "reset" anything permanently if you didn't back up.
Does that work normally? If not, try creating a new (blank) profile: [http://support.mozilla.com/kb/Managing+profiles Managing profiles].
Some people track down problem add-ons by selectively enabling and disabling them in groups, but this can be slow. The other approach is to ditch your old profile and move your key settings like bookmarks to the new profile. More info: [https://support.mozilla.com/en-US/kb/Recovering+important+data+from+an+old+profile Recovering important data from an old profile].
If you still get the ad even in a new profile, then it likely is caused by external software. Malware and spyware scans would be a good idea.
These tools (free versions) will supplement your existing security software, hopefully without causing any conflict:

I can no longer (since upgrading to the latest firefox) open up multiple tabs of the same page (something I need to be able to do when emailing and referencing multiple emails while writing one email). The only option it gives me is to 'switch to tab'.

I can no longer (since upgrading to the latest firefox) open up multiple tabs of the same page (something I need to be able to do when emailing and referencing multiple emails while writing one email). The only option it gives me is to 'switch to tab'.

I'll try to make this clear. I USED to be able to left click on a hyper link and the hyper link would open in a NEW tab. Now for some unknown reason the hyper link by default opens in the same tab (window). I have to right click the hyper link in order for it to open in a NEW tab. (Yes, my 'tools'> 'options'> 'tabs' are set to "open new windows in a new tab." (Please no answers telling me to get rid of the Ask toolbar because I don't have one.) Thank you.

Whenever I click on a link, firefox opens a new tab instead of opening the link in the existing tab. How do I correct this?

I open firefox and type in CNN(or any other item). When the link appears I click on it. Instead of opening in the existing tab, firefox opens a new tab.

Thank you for this information. I love learning new things!

Firefox 4 RC - 2nd Tab Group is deleted when closing and restarting

This seemed to work at first when I first upgraded to Firefox 4 RC. Then later in the day when working with Panorama Groups, I found that the 2nd tab groups disappeared that I created once I quit my browser and reloaded it. This happen each time I do this again.

Thanks, cor-el for replying, I am afraid it did not help, you see my problem doesn't lay in the closing part. I can make a more detailed explanation on my "problem". You see when I have many tabs open under a period of using Firefox 4 RC, while using some I close normally the ones I don't use just pressing the x button on the tab, it closes but here comes the spooky thing. When going to tab groups, it says the tab is still alive and I can't close it there... So restarting firefox will by instant get me all of those tabs I don't want to have opened and those that I want opened. Now the problem doesn't appear, if I do like this...
Open tabs I want, open tabs I will only look for a sec, go into tab groups "close" them there. Restart Firefox, they will not come. SO I am wondering is there any bug with closing normally the tabs I could send pictures of what happens....

Stop firefox opening multiple update tabs automatically

Hi there I'm having trouble with firefox opening up auto update tabs by itself. When you are on any site after about 5 seconds a new tab opens requesting you to auto update my video player. Then 5 seconds later another tab opens saying the same thing. and again. and again and so on perpetually. If left unattended for two minutes 85+ tabs will have opened. I am running firefox 30 on windows 7. I have found a temporary fix is to reset firefox. This works for a few days and then the update will occur 5-10 times in a session and then stop. Then a few days later it reaches critical mass and hijacks firefox, tab after tab after tab.
I would like to have gotten a screen shot but the reset lost the tabs. I don't think the problem will have shown in the troubleshooting diagnostic (mainly due to the reset). I have gone through my history and have managed to get the common URLs of the tabs.

During all this going on is a program file download/install box is appearing asking if I want to save the file. Its 1.2 meg entitled player_setup.exe from download source http://kyle.mxp2203.com/I2ETeZ9CRw3yY0pXQgCz3Ks7vFKYiPYoWpVJ7FDEM_LNTKNN4VpnFBNK408G1M9qRBUoGCRE1XTI-LPLDH-vsA-jFn3DLSvbup3AAcZaR3XjA8bbIoFhtsDY4dpBIl6j
I thought if I downloaded the file and ran it then the messages would disappear. The file was a media player file associated with multiple advertising addons that would be installed if you did a typical install. I did a custom install and only installed the player. This did not stop the problem. The tab thing remained. I have uninstalled the program. The problem existed a few weeks before I did this so installing was not a trigger for further attacks.
I have discovered that resetting firefox also breaks a few links. I have to re-allow popups and re-enable my java plugins. I am enrolled in a tafe course and it also runs a diagnostic. This is what it checks.

On top of the plugin assessment was a warning from firefox. "Firefox has prevented the unsafe plugin "java deployment toolkit" from running on www.mozilla.org continue blocking / allow. I chose to continue blocking.
I had a bit more of a look at my plugins through the add-on manager. Java deployment toolkit 7 was installed. And came up with a warning message that Java deployment toolkit 7 was vulnerable. On checking for more information I get diverted to
Add-ons for Firefox

Java Deployment Toolkit (click-to-play) has been blocked for your protection.
I have since disabled the plugin.
Can you shed any light on what is going on or have I stumbled across the solution by disabling the toolkit.
Hopefully we can address the issue before it gets hijacked again.
Please help cos I get really frustrated when it gets hijacked and I have to reset.

Kindly check the addons in your firefox

Firefox opens a blank tab when I open a pdf in adobe.

First of all, I have already gone into the setting and disabled the pdf viewer in Firefox and have it set to open in Adobe. However, when I click on a pdf attachement in an email or anywhere, the pdf now opens in adobe BUT, firefox still opens a blank tab. How do I get this to stop?
The little icon near all my pdfs (in emails and everything) has the little firefox logo in it.
I just want pdf's to open in Adobe with no new tabs opening.

What is the value of the plugin.disable_full_page_plugin_for_types pref on the about:config page?
Does that still contain the default application/pdf value that is used to prevent a plugin from opening?
You can open the about:config page via the location/address bar.
You can accept the warning and click "I'll be careful" to continue.

When I search for something, firefox opens a new tab with the results. How can I change the settings to where it will all stay in the same tab?

When I search something Firefox automatically opens a new tab with the results of this search. How do I change the settings to where the results will appear in the same tab as where I conducted the search?

Whether to open search results in new window most often is a setting of the search engine you are using.

When starting, Firefox opens an extra tab that is about Firefox. I am tired of it already!

Firefox Start Page opens, along wiht my homepage, when I open a new window.

How many pages do you have set as your "homepage"? 
Firefox allows for multiple homepages in separate tabs, separated by the pipe | symbol.
Try resetting your homepage.

Firefox opens window with tabs leading to garbled links

Almost every time I go to a site, firefox opens a new window with numerous tabs trying to access garbled links. The first tab looks like this: http://i56.tinypic.com/2nkuo9k.jpg.
Anti-virus programs found nothing, and re-installing firefox didn't fix it.

Do a malware check with some malware scanning programs. 
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.

How can I make firefox open with certain tabs?

I'm looking to make is so every time I choose to open Firefox, a few selected tabs open. For example, I open Firefox and a tab for Facebook opens, and tab for Twitter, a tab for news, etc. Wondering if there's a way to do this.

You can add the URLs separated by spaces to the target file of a (copy of) the Firefox desktop shortcut.
*https://developer.mozilla.org/Command_Line_Options
If you exceed the maximum length the use a cmd file instead to start Firefox.
* start "" "C:\Program Files (x86)\Mozilla Firefox\firefox.exe" <url1> <url2>

I want to have tabs open as app tabs on startup

I have a couple of tabs that I always use, so I pin them as app tabs. The problem is that I want to save them as my home page, but as app tabs, not regular tabs. If I open the tabs I want for my home page and press "use current pages" as home page, they open as regular tabs. Is there any way to manually specify which tabs should be app tabs and which should be regular tabs in preferences?

Yeah, I noticed that the tabs are restored as app tabs, but doesn't that mean that there should be a way to have them as your home page as well? Showing your windows and tabs from last time isn't really the same thing. Should I file a feature request or something?

Firefox keeps opening the same tabs on startup instead of the ones from last session

OS is winxp and firefox 3.6.8. This has been fine for a number of months. When closing FF it asks to save tabs and settings and I ok it. But it keeps opeing the same tabs from a week ago.
Can you help?

A couple of things to check.
Check to see if Firefox is set to open to your home page, if so have the sites that open been set as the home page. Those settings are on the [[Options window - General panel]].
Another possible cause is the file that stores details of sessions may be corrupt. You can delete the files that have details of sessions to see if that helps. Firstly you need to access your profile folder, for details of how to do that see the [[profiles]] article. Once you are in your profile folder, close Firefox and delete ''sessionstore.js'' and ''sessionstore.bak'' (the second file may not exist)
