Firefox keeps opening new tabs on its own...I've run virus scans and re-downloaded..HELP!

Ok, random tabs open in Firefox often enough to really get annoying. I don't want to switch back to IE (ew), but I will if I can't fix this. Normally, it's a Google ad that opens, but today, a site for adult products opened. I have a 13 yr. old daughter who does NOT need to see this.
Here's what I've done to try to correct this problem so far...
-I've un-installed and re-installed Firefox at leas 4 times
-I've run Malware Bytes Anti-Malware, Ad-Ware, AVG scans and Super Anti Sypware...multiple times
-I've deleted and replaced the dll file WS2_2.dll with a new one
-I've re-configured add-ons according to another support site.
Anyone got any better ideas? I really don't want to go back to IE! Please help!!

Hi Guys,
I'm not actually from Mozilla Firefox, but I've had this problem before, and I've solved it with the help from another website.
What you need to do is download a programme called "tdsskiller" from here:
http://www.geekpolice.net/t23369-computer-infected
scroll down the page and you should see a link. (I know the article itself seems irrelevant to your problem, but trust me, the programme they recommend works on this virus too.) It's only 1.3MB or so, so it doesn't take up huge amounts of space either! :)
I can safely say that it is COMPLETELY safe to download this from geekpolice.net, as this website is a free website which helps people with viruses on their computer. If you ever have another problem with anything to do with computers, go and have a look on geekpolice.net, they should have something that might help you.
Before anyone wonders why I am singing its praises so much, no I am not advertising them for any personal gain, but they have helped me get rid of some pretty nasty viruses on my computer before, so I am very grateful to them :)
SO, anyway, after you've downloaded the tdsskiller, you should run it, and it may find some infected files, in which case let it repair them. After rebooting your computer, the annoying opening tab thing should be gone!
I hope this works for anyone who's stuck :) If it doesn't, I'm really sorry, but it has definately worked for me!
Good luck!
Yashmeee :)

I have a new MacBook Pro. I am using firefox, but my homepage is set to google. Firefox constantly keeps opening new tabs to its own homepage by itself. How can I disable this feature?

I have a new MacBook Pro. I am using firefox version 7.0.1, but my homepage is set to google. Firefox constantly keeps opening new tabs to its own homepage by itself. How can I disable this feature.

Hi [email protected]
If you have set Google to be your homepage, that should be the first one to appear. Are you seeing the Firefox home page when you open new tabs? New tabs should be blank by default. The only reason I've seen Firefox open new tabs with Firefox data on it is after an upgrade of the product.

My firefox keeps opening new tabs and new windows, takes me to infected wedsites that my norton tells me. What can I do?

Tabs and new windows keep opening. My norton tells me that I am accessing known infected websites.How can I fix this.
Thank you

Firefox keeps opening "new tabs" in a whole new firefox session.

OK so this is probably an easy fix but I just had to wipe my comp and I am in the process of getting all my stuff back so my mind is muddled. That's my excuse anyways.
My issue is that when I click "open a new tab" Firefox will open a whole new browsing session instead of just a new tab next to the one I am currently on. I have already tried fixing it by going to options and mucking about the tabs options but nothing seems to be helping it.
Thanks in advance for any help and sorry if this is a repeat question but I couldn't find it on here.

Latest version of firefox keeps opening new tabs when I don't want it to - how can I stop it from doing that?

I'm running 8.01. Another PC next to me is at 8.0, and it doesn't do that.

"Clear the Cache": Tools > Options > Advanced > Network > Offline Storage (Cache): "Clear Now"
"Remove the Cookies" from sites causing problems: Tools > Options > Privacy > Cookies: "Show Cookies"
If clearing the cookies doesn't help then it is possible that the file ''cookies.sqlite'' that stores the cookies is corrupted.
You can rename (or delete) '''cookies.sqlite''' (cookies.sqlite.old) and delete '''cookies.sqlite-journal''' and '''cookies.txt''', if they exist, in the [http://kb.mozillazine.org/Profile_folder_-_Firefox Profile Folder] in case cookies.sqlite got corrupted.

When I want to mail a web-page or link firefox keeps opening new windows and cannot be stopped.

My laptop is a Samsung R730 (quite happy with it). I use Eudora for e-mailing. If I want to mail a web-page or link and click under 'file'to send it, Firefox starts opening new tabs without stopping up to over a hundred. I have to brutally switch off my lap-top, start agaiu. Restart Firefox which wants to open all the old tabs, click it off quickly. After that I can reopen to normal.

You get that problem if you select the Firefox program to handle a file if you get an "open with" dialog.

Why does my browser keep opening new tabs

My browser either Safari or chrome keeps opening new tabs with adds almost like pop up what can i do to stop them? This all started when i upgraded to yosemite

There is no need to download anything to solve this problem. You may have installed a variant of the "VSearch" ad-injection malware. Follow Apple Support's instructions to remove it.
If you have trouble following those instructions, see below.
Malware is always changing to get around the defenses against it. This procedure works as of now, as far as I know. It may not work in the future. Anyone finding this comment a few days or more after it was posted should look for a more recent discussion, or start a new one.
The VSearch malware tries to hide itself by varying the names of the files it installs. To remove it, you must first identify the naming pattern.
Triple-click the line below on this page to select it, then copy the text to the Clipboard by pressing the key combination command-C:
/Library/LaunchDaemons
In the Finder, select
          Go ▹ Go to Folder...
from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.
A folder named "LaunchDaemons" may open. Look inside it for two files with names of the form
          com.something.daemon.plist
and
           com.something.helper.plist
Here something is a variable string of characters, which can be different in each case. So far it has always been a string of letters without punctuation, such as "cloud," "dot," "highway," "submarine," or "trusteddownloads." Sometimes it's a meaningless string such as "e8dec5ae7fc75c28" rather than a word. Sometimes the string is "apple," and then you must be especially careful not to delete the wrong files, because many built-in OS X files have similar names.
If you find these files, leave the LaunchDaemons folder open, and open the following folder in the same way:
/Library/LaunchAgents
In this folder, there may be a file named
          com.something.agent.plist
where the string something is the same as before.
If you feel confident that you've identified the above files, back up all data, then drag just those three files—nothing else—to the Trash. You may be prompted for your administrator login password. Close the Finder windows and restart the computer.
Don't delete the "LaunchAgents" or "LaunchDaemons" folder or anything else inside either one.
The malware is now permanently inactivated, as long as you never reinstall it. You can stop here if you like, or you can remove two remaining components for the sake of completeness.
Open this folder:
/Library/Application Support
If it has a subfolder named just
           something
where something is the same string you saw before, drag that subfolder to the Trash and close the window.
Don't delete the "Application Support" folder or anything else inside it.
Finally, in this folder:
/System/Library/Frameworks
there may an item named exactly
            v.framework
It's actually a folder, though it has a different icon than usual. This item always has the above name; it doesn't vary. Drag it to the Trash and close the window.
Don't delete the "Frameworks" folder or anything else inside it.
If you didn't find the files or you're not sure about the identification, post what you found.
If in doubt, or if you have no backups, change nothing at all.
The trouble may have started when you downloaded and ran an application called "MPlayerX." That's the name of a legitimate free movie player, but the name is also used fraudulently to distribute VSearch. If there is an item with that name in the Applications folder, delete it, and if you wish, replace it with the genuine article from mplayerx.org.
This trojan is often found on illegal websites that traffic in pirated content such as movies. If you, or anyone else who uses the computer, visit such sites and follow prompts to install software, you can expect more of the same, and worse, to follow. Never install any software that you downloaded from a bittorrent, or that was downloaded by someone else from an unknown source.
In the Security & Privacy pane of System Preferences, select the General tab. The radio button marked Anywhere should not be selected. If it is, click the lock icon to unlock the settings, then select one of the other buttons. After that, don't ignore a warning that you are about to run or install an application from an unknown developer.
Then, still in System Preferences, open the App Store or Software Update pane and check the box marked
          Install system data files and security updates (OS X 10.10 or later)
or
          Download updates automatically (OS X 10.9 or earlier)
if it's not already checked.

Firefox not open new tabs

My Firefox not open news tabs on popups, and not show bars.
and can't move tabs on popups to main windows.
sorry my bad english

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

Why does Firefox keep opening new Windows rather than a new Tab in the current window?

I have " Open a new Tab in the current Window" select in Preferences.
Why then does this version (Version 4) keep opening new Windows, rather than new Tabs in the current Window.
This feature worked fine in 3.6.1.3, but in Version 4, it is a frigging pain in the rigging!
C'mon, Mozilla - time for an URGENT update ...

Firefox is opening new tabs on corrupted sites on it's own

I am using Firefox on a Samsung NC10 running XP Professional.
About 4 weeks ago I was hit with a fake Malware virus, which I have successfully removed using Malwarebytes and Registry Mechanic.
Since then Firefox is periodically opening new tabs for no reason which invariably take me to unsafe corrupted websites.
Can you tell me how I can stop this happening

I have solved this problem on my computer using the Microsoft® Windows® Malicious Software Removal Tool from here:
http://www.microsoft.com/downloads/en/details.aspx?FamilyID=ad724ae0-e72d-4f54-9ab3-75b8eb148356
My computer was also unable to access the Microsoft update site, so I had to use another computer and a usb drive.
I ran a full scan which took several hours, but it found an infection that Malwarebytes and AVG didn't.
Following the scan I was able to update from Microsoft update and, so far, no more spurious pages starting on their own

Recently firefox started opening new tabs when I click on search results how do I get this to stop

When I use Google and I click on a search result it opens a new tab where it used to just take me to a new page in the tab I was using I was looking in the tabs tab in options and saw I could choose it to open in a new window but I don't see an option to open it in the current tab. This started happening out of nowhere.

Found a setting in Google that was telling it to open all result in a new Windows which I was guessing that Firefox was overriding and open it in a new tab like settings suggested unchecked the box in Google and now the behavior is back to normal.

Firefox initially opens new tabs as tabs, then switches to new windows

I am running FF 14.0.1 and the following problem has persisted through a number of versions.
Initially FF will open new tabs...Ctrl+t works, right-click open in new tab etc. all work fine. Sometimes tabs are now issue and I can have maybe 20 or more tabs open. Then other times we seem to get to some arbitrary limit, say 5 tabs, and from then on every new tab opens a new window. Any external link opens in a new window, a Ctrl+t opens as a new window, all new windows are single frame, e.g. you can't have a number of windows each of say 5 tabs, just the original window with (say) 5 and then a series of windows with only single pages in each and from which Ctrl+t only opens a new window.
A complete restart does sometimes cure things and I can go back to having different pages in different tabs, and then something...no obvious pattern...kick us into 'new window only' mode after which even if I reduce the number of tabs in the original multi-tabbed window, Ctrl+t only opens new windows.
It's really starting to get to me... I've trawled the support info and am wondering about a complete reset or even uninstall and re-install. places.sqlite is checked as being valid and I've reindexed it too, all to no effect.

Well I think the following shows the odd state FF has got itself into. So I...
# Located the profile folder
# Closed FF (14.0.1)
# Renamed (rather than deleted) the localstore.rdf file
# Restarted FF in safe mode
The main point then was that excepting the change in layout, that tabs didn't work at all; the option was greyed-out, the + tab did nothing and Ctrl+t did nothing.
The then stopped, deleted the new localstore.rdf and restored the old/orginal one and restarted. This restored my layout by still new tab is entirely gone...the option is greyed-out in the menus, the + tab dodn't work and Ctrl+t does nothing. Ctrl+n does give a new window. In addition:
# The forward and back buttons have disappeared
# The toolbars have disappeared despite showing as enabled in the View:Toolbars menu
Opening a new windows however give a correct layout, e.g. back and forward and toolbars appear and New tab is enabled, however, it either via menu of via Ctrl+t only opens new windows.
The start in Safe mode sadly didn't seem to help, but I will experiment further...
Images:
# Note the loss of back and forward buttons and no toolbar
# This is simply a Ctrl+n new window...back and forward arrows and toolbars restored
# This is in the 'parent' multi-tabbed window (with no back/forward etc.). Note how New tab is greyed out explaining why + tab and Ctrl+t simply doesn't work...doesn't open new window, simply does nothing at all

Firefox keeps opening itself on it's own after PC startup

Two days ago I encountered this problem. Each time my PC would start, FireFox would open itself on it's own and display the home page. I tried scanning the system with Avast! Antivirus and MalwareBytes AntiMalware, but nothing has been found. Could it be that some of the add-ons are forcing Firefox to do so, or do I have some sort of malware that my AV programs can't find?

I looked under both locations, and found nothing. When I typed in msconfig in Start>Run..., I checked System Configuration Utility, and found one process that puzzled me... http://img821.imageshack.us/img821/3281/wuththehell.jpg
I unchecked it and closed the window after saving, but didnt restart. Later on I decided to take a look at it again, and when I opened the window, the process was gone.

Why does Firefox repeatedly open new tabs when I open a .php file?

Hey guys!
I do web development and design. I've just set up my PC (Ubuntu 14.04 LTS) and installed my choice of software.
On the .php files I set Firefox as the default software to open with but now it opens about 50 odd tabs in the space of 3 seconds. How do I fix this?
Kind regards,
-Trey

You've hit a bug that happens when you set Firefox as the external "helper" application used to open a type of file (the "Warning!" paragraph [http://kb.mozillazine.org/File_types_and_download_actions#Setting_an_automatic_action here] links to the related bug reports, if you're interested).
See [[Firefox repeatedly opens empty tabs or windows after you click on a link]] for how to fix this.

View in external browser keeps opening new tabs

Recently, in a failed effort to address the new version's inability to close successfully, I reset Firefox. I seem to have lost another valuable setting, and I can't remember how to recreate it.
I use a peculiar, old html editor. When I ask it to "View in External Browser," naturally it opens Firefox. (I forget whether I created that setting or if it inherited it for me from my default in Windows.) In the past, if I asked to do so more than once, following further edits, it would open in the same tab, or rather in whatever tab was on top. Now, since my reset, it opens a new tab, and I can get a distressing number of them.
What setting have I forgotten to change, presumably in Firefox itself or Tab Mix Plus? Thanks,

As I say, I'm reluctant to change that about:config setting until I have to, since (1) it's not clear to me what it does and (2) I'm dead sure it's not an about:config setting I've ever had to touch before, so it couldn't possibly recreate my former behavior.
Now: I went into Tools, Options, Tabs and made sure that Open Links That Open in a New Window read Current Tab. Still, it was getting weird: even Googling for a site and then clicking on the search find opened a new tab, as if I really want to keep the Google listing. I'm sure I'd never seen that before on multiple computers over the years. Have others? Truly weird what v29 with Reset has done.
Next, I opened Tab Mix Plus Options and found I had the same option, weirdly enough, still set to New Tab, so I changed it. This stopped anything at all from opening in a new tab.
Now, it's progress, but I'm sure my old browser behavior was more intuitive than that. Some things really did open a new tab, such as external links in Facebook posts. I know I can get that from right-clicking, but I didn't have to. Now I'm still confused as to how much Firefox has changed on me in the last three weeks and how much time it has taken to try to adjust it. I've never been clueless at the computer before.

Firefox keeps opening new tabs on its own...I've run virus scans and re-downloaded..HELP!
