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 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 ...

That issue can be caused by an extension that isn't working properly.
*https://support.mozilla.com/kb/Troubleshooting+extensions+and+themes
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.

How do I set Firefox to open new windows in a separate window (not in tabs)?

How do I set Firefox to open new windows in a separate window (not in tabs)?

Click the orange Firefox button, and click "Options". This will bring up a new window with a "Tabs" tab at the top. Click that. There will be several checked boxes, including one called "Open new windows in a new tab instead" up at the top of the list. Uncheck that box and you should be good to go.
ETA: This should also work if you click "Tools" and "Options" within your version.

When I click on a pdf doc on a site, Firefox begins opening new windows until I quit the application. On a mac.

The dialog box of downloads that appears on Firefox after a download is complete shows the document as a .pdf. (of course this is after I restart Firefox). However, in my user/downloads folder, the document is .pdf.part

I have not checked "Open new windows in a new tab instead" but Firefox 5 keeps opening new windows in a new tab. How do I stop this?

I do not want to use the tab feature.
I have an iMac OS 10.6.8

(''Note: cross posted from [https://support.mozilla.com/nl/questions/801471 here].'')
I had the same problem, but was able to fix it somewhat.
# Open the about:config page.
# Set the ''browser.link.open_newwindow.restriction'' setting to 0 (= zero).
On my machine this will open new windows in a new tab. However, it switches to the new tab regardless of the setting ''"When I open a link in new tab, switch to it immediatly"''.

How do I set Firefox to open new windows in my second monitor?

When opening a new window (by right clicking a link and selecting Open in New Window), I would like the window to be opened in my second monitor. Firefox used to do this, but randomly stopped. Now when I open a new window it is opened in my primary monitor. It does not open maximized (just short of being completely maximized). I have tried the fix I used before- moving the un-maximized browser to the second window, closing and re-opening the window. I have also tried moving the un-maximized browser, maximizing, closing and re-opening. Does anyone know how I can restore Firefox to open my new window in the second monitor?
== This happened ==
Every time Firefox opened
== Randomly

Click the orange Firefox button, and click "Options". This will bring up a new window with a "Tabs" tab at the top. Click that. There will be several checked boxes, including one called "Open new windows in a new tab instead" up at the top of the list. Uncheck that box and you should be good to go.
ETA: This should also work if you click "Tools" and "Options" within your version.

Firefox is opening new windows automaticly most often when I move the curser

Firefox has started opening new windows that show redirect. This happens most often when I move the curser. The problem is intermittent as it seems to stop when you close all the windows at times. Then when you go to a new page it starts opening new windows again.

If this affects a lot of sites randomly, there's a good chance it is caused by an add-on. Try this:
Disable ALL nonessential or unrecognized extensions on the Add-ons page. Either:
* Ctrl+Shift+a
* "3-bar" menu button (or Tools menu) > Add-ons
In the left column, click Extensions. Then, if in doubt, disable (or if obviously bad, remove).
Usually a link will appear above at least one disabled extension to restart Firefox. You can complete your work on the tab and click one of the links as the last step.
Does that shut down the extra windows?
Also recommended:
(1) Visit the Windows Control Panel, Uninstall a Program. Click the "Installed on" column heading to group by date. Then look for any recent unrecognized programs that may have snuck in as part of a bundle. Remove everything you do not know to be useful and trustworthy.
(2) Our support article lists some other scanner/cleaner tools that you may find helpful: [[Troubleshoot Firefox issues caused by malware]].

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.

I used to work on few open windows with a number of open tags, for some reason firefox stopped opening new window, any reason why?

I have been using firefox for a while. I usually work on a number of windows (sometimes up to 8) with 8 - 10 tags in each. I was using a trial version of Nero and was triggered for an upgrade which i stopped half way through. I dont know if this has caused this problem. Now I cannot open any link in a new window. It will only open in a new tag of the same window.
== This happened ==
Not sure how often
== when i stopped an upgrade from Nero

-> IF you use Privacy Cleanup softwares like CCleaner, DON'T SELECT FIREFOX IN ITS SETTINGS. These softwares can be responsible for Deleting your Firefox Settings.
Perform the suggestions mentioned in the following articles:
* Make sure you are using the '''"Remember History"''' setting as described in this article -> [[Settings for privacy, browsing history and do-not-track]]
* [[Restore previous session - Configure when Firefox shows your most recent tabs and windows]]
Check and tell if its working.

Firefox cannot open new windows

I have done everything possible to fix this issue. When I install firefox, there is no issue with opening extra windows (not tabs). However once the computer is restarted, and firefox brought up, it will not open links in new windows but will open it in tabs.

You can check some prefs on the about:config page to be sure that these are correct.
*http://kb.mozillazine.org/browser.link.open_newwindow
*1: current tab; 2:new window; 3:new tab;
For links opened via JavaScript you can look at this pref:
*http://kb.mozillazine.org/browser.link.open_newwindow.restriction
Start Firefox in [[Safe Mode|Safe Mode]] to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.

How do I prevent Firefox from opening all tabs in seperater windows?

Every single time I open Firefox it not only opens all of my previous tabs in one window but it also opens each and every one of them is it's own separate window. As I normally work with over 60 tabs it takes several minutes for them to complete opening and is a pain. Anyone who knows how to control this please help. I've checked all of the existing issues and find it surprising I'm the only one reporting this problem.

It is possible that there is a problem with the files sessionstore.js and sessionstore.bak in the Firefox Profile Folder.
Delete the files sessionstore.js [2] and sessionstore.bak in the Firefox Profile Folder.
* Help > Troubleshooting Information > Profile Directory: Open Containing Folder
* http://kb.mozillazine.org/Profile_folder_-_Firefox
If you see files sessionstore-##.js with a number in the left part of the name like sessionstore-1.js then delete those as well.
Deleting sessionstore.js will cause App Tabs and Tab Groups and open and closed (undo) tabs to get lost, so you will have to create them again (make a note or bookmark them).

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 :)
