Every time I open a new Firefox window a dowload dialog box opens

Every time I open a new Firefox window, a download dialog box opens with the last youtube .flv file that I converted to an mp3 from www.flv2mp3.com and the box offers the options to open it or save it. I have to click cancel it every time (or try opening it or saving it) to make it to go away. If I open a new tab or new window while I still have the original window open, it doesn't do it. Is this a glitch in Download Helper or did I get a never ending script from flv.com, or what?

You can check the target line in the Firefox desktop shortcut (right-click: Properties) to make sure that nothing is appended after the path to the Firefox program.
Do a malware check with several malware scanning programs on the Windows computer.

When I open a new firefox window, and click the + to open a new tab, my first page disappears - I can only seem to return to it by closing all the other tabs.

The issue occurs like this:
1. Open a new window
2. Enter a URL and go to a page (any page).
3. Click the + and open a new tab.
4. The first tab is no longer visible in the tabs bar.
5. I keep opening lots of other tabs and the first tab stays invisible (all the others stay visible / accessible).
6. The only way I've found to return to the first tab is to close all my other tabs.
This doesn't always happen (i.e. I can have two firefox windows open and only one of them does it!)
I'm not sure if it's a feature or something? But it's very annoying!
Any ideas welcomed.
Thanks

Hi - yes I can! I hadn't noticed that little arrow before, thanks.
However I would really like to stop it hiding the first tab all the time.... Even when I navigate to the first tab using that "list all tabs" arrow, it still remains 'hidden' (i.e. I can't see a tab up the top, even when that tab is active. And when I navigate away from it to another tab, it is invisible again).
Any ideas?
Thanks

Boot the computer in Windows Safe Mode with network support (press F8 on the boot screen) as a test to see if that helps.

Firefox does not open a new tab when you click the plus sign button which is actually a shortcut for opening a new tab. You have to open a new firefox window in order to get a new tab. Please help. Thanks.

I didn't have this problem before with Firefox. My kids must have pressed something or clicked on something that's the open new tab button does not function anymore. No matter how you click it, it doesn't open a new tab. Even if you click on file, then go to new tab, it still doesn't open a new tab. You have to open a new firefox window in order to do multiple browsing.
Hope you can help resolve this problem.
Sincerely,
Ems Guillarte

Uninstall the Ask toolbar and it should work again. There is a compatibility issue with the Ask toolbar and Firefox that prevents new tabs from being opened. Checking your list of add-ons, the MyPlayCity toolbar is a version of the Ask toolbar.
There are a couple of places to check for the Ask toolbar:
* Check the Windows Control panel for the Ask Toolbar - http://about.ask.com/apn/toolbar/docs/default/faq/en/ff/index.html#na4
* Also check your list of extensions, you may be able to uninstall it from there - https://support.mozilla.com/kb/Uninstalling+add-ons

Clicking the scroll wheel does not open a new firefox window

I'm running Windows 7 x64 SP1. I use the scroll wheel to click items in the task bar to open another instance of those items. Eg I scroll-click a Firefox or Excel or Explorer or whatever item in the taskbar, and it opens another instance of that program. I use this feature to open a new instance of FireFox rather than switching to the FF window, then using control-n to open a new window.
I just upgraded to FireFox 6 from FF4.x. Since doing so, scroll-clicking the FF item in the taskbar does not open a new FF window. It does, well, nothing.
I installed FF6 on a clean Win7 x86 (RTM) build in a VM. When I use the scroll-click feature in the taskbar, it works as expected: it opens a new FF window.
Things I have tried: A different mouse; updating video drivers (I doubted this would make a difference, but it needed to be done anyway, so I thought I'd mention it); running FF in safe mode (ie with all plugins etc disabled).
I'm doing a little experimentation right now with respect to x86/x64, RTM/SP1, clean FF6/upgrade from 4.x and other differences that might highlight why it works as expected in my VM but not on my physical machine.
I'm curious to know if anyone else has experienced this problem since upgrading to FF6.
Max

Respectfully, that answer isn't particularly helpful. I have already demonstrated that middle-clicking (mouse wheel click) will open a new instance of FF, and other programs. This was true before the upgrade from FF4 to FF6, and is true on all my VM builds (Windows 7 default install with nothing but FF installed).
Nevertheless, I've tried shift-left-click, and it does not open a new instance. It will only open a new instance if I pin FF to the taskbar, which I have already stated I do not want to do. This new behaviour is unique to FF. Other applications (Word, Excel, Internet Explorer, whatever) all behave as expected. It is only Firefox that is misbehaving, and it is only misbehaving since the upgrade.
My issue is that FF has changed its behaviour with respect to middle-clicking since upgrading from 4 to 6. I'd welcome helpful comments about getting FF to behave.
Max

Every time I open a new FireFox window or tab Bing opens instead of my home page.

How do I stop Bing from opening everytime I start FireFox, open a new window or tab in FireFox? When FireFox starts I have my options set to open with my homepage.

When I open a new firefox window, all curernt minimized firefox windows maximise!! Why do they maximize, and how do I stop them maximizing.

'''bold text'''Browser:- Firefox 4.0.1
OS:- Windows XP SP3.
It happens every time I open a new window.
This very annoying, especially when i can have up to ten window active at a time. I group my windows by subject matter, and may have several tabs open in each window.

The ASK.com Toolbar can cause other windows to get maximized.
Start Firefox in [[Safe Mode]] to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).

In Mac OS 10.6, why won't the command n keyboard shortcut open a new firefox window?

Ever since Firefox 3, command n does not open up a new window. I'm on a Mac, OS 10.6

Hello cor-el,
Yes, I do use a 2 monitor set up. And Yes!!! moving the Firefox window to the main or 1st monitor allows use of command n shortcut to open a new window. You're a genius. Thank you soo much!
Naturally, the reason I use a 2 monitor set up is to have Firefox open on the 2nd monitor for quick reference and easy access. Is there a workaround that will allow me to keep this configuration? (I know, I'm getting greedy now!)
Many Thanks,
stevep50

How to get links from other applications to open a new Firefox window

I have non-Web browser applications that want to open browser windows. I have Firefox as my default Web browser. When these other applications pass a URL to Windows, Windows passes the URL to Firefox. Unless there are no Firefox windows running, Firefox then opens the URL in a new tab of the most recently used Firefox window. I would prefer that Firefox open a completely new window. Where can I find the setting for this behavior?
Thank you,
Dan

After closing a browser window and if I open a new browser window , the browser will not open per my home page in tools/options/startup, it loads the last page

recently when opening a new browser, everything Is using and closed during my last session will open
multiple widows will open and whatever tabs were open per respective windows will open and not per tools/options/startup/homepage
this has never happened until just recently and nothing else seems to have changed nor has any new programs etc been loaded or changed

You can check if you have a user.js file in the Firefox profile folder that sets the browser.sessionstore.resume_session_once pref to true.
*http://kb.mozillazine.org/browser.sessionstore.resume_session_once
You can use this button to go to the currently used Firefox profile folder:
*Help > Troubleshooting Information > Profile Directory: Show Folder (Linux: Open Directory; Mac: Show in Finder)
Note that Windows hides some file extensions by default.
Among them are .html and .ini and .js and .txt, so you may only see file name without file extension.
You can see the real file type (file extension) in the properties of the file via the right-click context menu in Windows Explorer.
You can check for problems with the sessionstore.js and sessionstore.bak files in the Firefox profile folder that store session data.
*Help > Troubleshooting Information > Profile Directory: Show Folder (Linux: Open Directory; Mac: Show in Finder)
*http://kb.mozillazine.org/Profile_folder_-_Firefox
*http://kb.mozillazine.org/Multiple_profile_files_created
Deleting sessionstore.js will cause App Tabs and Tab Groups and open and closed (undo) tabs to get lost and you will have to recreate them (make a note or bookmark them if possible).

Firefox 4 opens a new firefox window for every tab I open

Everytime i open Firefox 4, all my old saved tabs are opened in their own new window in addition to being put on my tab bar. Each new instance of the windows has all access to all the other tabs from the original window as well

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 and sessionstore.bak in the Firefox Profile Folder.
* Help > Troubleshooting Information > Profile Directory: Open Containing Folder
* http://kb.mozillazine.org/Profile_folder_-_Firefox
* http://kb.mozillazine.org/sessionstore.js
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 to get lost, so you will have to create them again (make a note).

How do I prevent tabs in the task bar from opening everytime I open a new Firefox tabs from the Start Menu?

I have four tabs in my task bar at the bottom of my computer screen. If I go to Start and open a new Firefox window then all four tabs open automatically. How do I prevent all the tabs from opening?

Home Screen > YouTube App > Settings (Gear icon) > Open Links with Chrome
Slide the button to turn it off.

Link in emails to open the link in new tab, not a new firefox window with home page,

Link in emails open a new Firefox window with my default home page. How do I get Firefox to open the linked web page, in an new tab, as it used to do??
This is for Win XP, FF 17.0.1, using Outlook as mail client.

Do you mean the results from a search via the Google search bar on the Navigation toolbar or the Firefox Google home page (www.google.com/firefox) ?
For the Google website you can set your preferences on the Google.com page via the [http://www.google.com/preferences?hl=en Google Search settings] link at the top right.
Results Window: Open search results in a new browser window.
You need to allow cookies for Google (Tools > Page Info > Permissions) to save that setting, otherwise you have to repeat it.
For the Google search bar on the Navigation toolbar you can set the pref browser.search.openintab to true on the about:config page.
To open the about:config page, type about:config in the location (address) bar and press the "Enter" key, just like you type the url of a website to open a website. 
If you see a warning then you can confirm that you want to access that page.
