Firefox 9 opens new window when opening new tab on Windows 7

When I load FF 9, then click on the + to open a new tab, it does, but in the quick start in Windows 7 taskbar, it also shows another FF window, even if the new tab "seems" to be in the original instance of and seq., what I mean is, if I have 4 tabs open, it shows 4 Firefox Windows in the taskbar.

Is there any solution for this?

Thank you and best regards,
Clive

  • Firefox 8 puts new tabs opened from links in another tab at the end of the list, NOT next to the tab it just as in V3.6. I want it next to the tab that it comes. How can I do this?

    Question as noted, sums it up. When I click on the mousewheel on a link in a tab, for I want a new tab open with that link and want it beside the tab, I clicked on the link in any as Firefox V3.6 has done. Firefox 8 is always open the new tab at the end of the list and boy is that embarrassing!

    Please tell me how to solve this problem.

    Define the Boolean browser.tabs.insertRelatedAfterCurrent true pref on the topic: config page.

    To open the topic: config page, type Subject: config in the address bar (address) and press the 'Enter' key, as you type the url of a Web site to open a Web site.

    If you see a warning then you can confirm that you want to access this page.

    • Use the filter at the top bar of the on: page config to more easily spot a preference.
    • Preferences that have changed also show "BOLD" (user set).
    • Preferences can be reset to the default value using the context menu if they are set of users
    • Preferences can be changed via the context menu: Edit (string or integer) or toggle (Boolean)

  • Whenever I open Firefox, or a new tab, I get a page "this address is not valid.

    I tried to change it manually on the subject: config and it still does not work.

    Do a clean reinstall and delete the program folder before Firefox to (re) install a new copy of the current version of Firefox.

    If possible to uninstall your current version of Firefox to clean the Windows registry and settings in the security software.

    • Do NOT remove the "personal data" when you uninstall your current version of Firefox, because this will remove all profile folders and you lose personal data such as bookmarks and passwords including data profiles created by other versions of Firefox.

    Delete the program folder Firefox before installing newly downloaded copy of the Firefox installer.

    • (32-bit Windows) "C:\Program Files\Mozilla Firefox\"
    • (Windows 64 bit) "C:\Program Files (x 86) \Mozilla.

    Your bookmarks and other personal data are stored in the Firefox profile folder and will not be affected by a uninstall and (re) install, but do NOT delete personal data when you uninstall Firefox which removes all Firefox profile folders and you lose your data.

    If you keep problems also create a new profile.

  • When you open a PDF saved on my computer, Firefox will open several tabs for all of the PDF files I have in a folder. Why?

    Recently, I tried to open some files in Adobe to view on my company computer. They have been recorded on my shared drive companies, and everyone seems to be able to open the files very well. When I try to open the files the program proceeds to open Firefox and wonder through the internet, if I want to download the file. At the beginning it wasn't a problem, because it was just a minor inconvenience. So today, I was working in a folder containing several files PDF (about 125 to express my frustration) and when I click on a file to open it, Adobe proceeded to open all PDF files in the folder. This means that each file opened a new tab in Firefox and proceeded to ask me if I wanted to download it. As I hope you can tell, I quickly became frustrated because I wanted only one file and it would not stop opening new tabs to ask me the same question 125 times. The only way to stop it was to open the Task Manager and go forward to force Firefox altogether.

    I tried to update the program on my computer (it was already up to date), I tried to update the plugin Firefox (it was already up to date) to adobe, I tried the repair Adobe Reader Installation (it doesn't make a difference), and I searched the internet for information about the problem (I was not successful in finding something that relates). According to me, the only thing that I did is to uninstall and reinstall the program on my computer, something I do not want to make I already said that it is a company computer.

    If there is someone who can help me solve this problem, I would be very grateful. Thank you for your time.

    Then, you need Adobe Reader, the default application to open PDFs, instead of FireFox. I think that FireFox just started doing this, and it is causing some confusion.

    As well as the normal way of Windows to change the default application, which is not also known as it should be, you should be able to use Adobe Reader. In Edit > Preferences in the General section and see if there is a button "select default PDF Manager."

  • Firefox always opens all tabs that were open when last closed

    Firefox, started out of the blue, to always show my tabs in the last session when it is started. I checked Firefox not listed in the Task Manager list after closing. So I tried the following:

    -change the "Startup of Firefox" option to all three of the available choices
    -Change the setting browser.startup.page 0 manually via "subject: config.
    -from Firefox in safe mode.

    None of them changed the behavior. It nevertheless opens the tabs that were open last.

    I'm under V25.0. Any suggestions? It is a major nuisance.

    You can check if you have a user.js file in the Firefox profile folder that affects the pref browser.sessionstore.resume_session_once true value.

    The user.js file appears only if you or another software created, therefore, normally, he wouldn't be here.
    You can check its contents with a text editor if you do not create this file yourself.

    The user.js file is read whenever you launch Firefox and initializes the preferences to the value specified in this file, so set of preferences via user.js can be changed temporarily for the current session.

  • Firefox (yet) open several tabs when I open any PHP file

    I tried all of the fixes suggested in your article, including removing mimeTypes.rdf, change the default browser for files PHP and my PC for malware analysis. The problem is still ongoing. Any ideas? Thank you.

    Thanks much for the reply, cor - el. I've been teaching myself PHP for the last month or two, so I downloaded on my PC at home of Apache and PHP files are mine. In fact, the problem of multiple tabs started right after I updated Firefox to version earlier this week. The strange thing is that the same PHP files open perfectly fine before the update.

    In any case, I found a workaround on www.bleepingcomputer.com. Instead of double-clicking the PHP file, which causes the problem of multiple tabs, I type the path of the PHP (for example, localhost/index.php) file in the URL in Firefox toolbar. The file works as before without having to open the tabs. It is not an ideal solution, but it will do for now.

  • FireFox 19 - stop new tabs to move to Yahoo Search

    I have Firefox 19.0.2. When I run it, it opens with Google Search (n. b., that's what I want). When I open a new tab, however, he indicates that he he has switched to Yahoo Search. I have to click on "Homepage" so he can go to Google Search.

    Most of the solutions I found on the Internet were rewritten in 2009 or 2010, and solutions do not work. I tried to enter ' subject: config' in the URL line and search for "default page" and "search here", but I can't find anything like that.

    I tried uninstalling Firefox and reinstalling it, but I still have the same problem - the first tab is as I want, but each new tab I open Yahoo Search. I suspect it's because I kept the customer file and my favorites.

    I would be extremely grateful to anyone who can tell me how to make new tabs open with Google Search and get rid of Yahoo Search. Thank you

  • Firefox isn't me WARNING when closing multiple tabs and it should be, and the ability to save tabs missing

    Hi all

    Not sure if it's something with Firefox 30, but this problem appears again.

    In fact, first when I was close the browser with multiple tabs open, it warned me with the little popup, but it wasn't the "do you want Firefox to save your tabs for the next time it starts? It was just the warning of closure which said "you are about x tabs. Are you sure that you want to continue? »

    So, who was recently #1 problem. I want the option to save and exit. But only in the last few days, it seems, is not even show this close attention now. With several tabs open, it closes just to the bottom of the browser. When opening Firefox again, tabs have been restored, at least it's a good thing, although weird.

    I wonder how come back asking to "Save and exit" or "Quit" or "Cancel" as before.

    In response to some requests for information as possible, here is some information that you may be asking, which I already checked:
    -as appropriate on: configuration settings are all set to true already, such as browser.tabs.warnOnClose and browser.showQuitWarning
    -in tools > Options, "warn me when closing multiple tabs" is checked, and "show my windows and tabs from last time" is selected for the start of Firefox. Nothing has changed!
    -safe mode does not solve the problem; Firefox closes always just if I quit or press the red X.
    -"Always use the private browsing mode" is unchecked.
    -I didn't run a program like CCleaner between sessions

    I have not changed anything, but this problem happening! I hope someone can help me to solve this problem and go back to the way it was, where accidentally close Firefox could be avoided and restore the previous session was possible.

    Thank you!

    Well well, with more tests and the help of my boyfriend, what I've learned, it's that tabs "Save and exit" dialogue prevails over the caveat to the closure of several tabs.

    With browser.showQuitWarning set to true, it will ask me to save and exit - but not if "show my windows and tabs from last time" is selected to start Firefox, who dismisses the prompt to save and leave (and close several tabs warning). It will save just for you to quit smoking.
    And had I disabled this browser.showQuitWarning manually or by selecting "do not ask next time" on the Sava and dialogue to quit smoking, then the warning for closing multiple tabs seems to try to close multiple tabs, since I warn the option in my settings of the tabs.

    It is one or the other, save and exit or warning to the closure of several tabs.
    It would be nice but if it was not a conflict between the fence several warning tabs and Firefox abandoning dialogue.

    So, I hope this can help someone else who may be confused or accidentally to change options and potentially be screwed on. After all, I can an injury self-inflicted in the settings.
