Can opening multiple tabs in Firefox slow down my computer (desktop)?

No further details.

That is possible if there are a lot of tabs open with active content (plugins or scripts) that need to be updated. It shouldn't make a difference for websites that only have text on current computers. But be cautious with websites that have a lot of Flash content.

  • Can I open multiple tabs in Firefox when WINDOWS starts up? Command line limits to about 204 characters...

    I know how to configure Firefox so that it opens multiple tabs every time you open ''Firefox''. I want it to open multiple tabs when I start ''Windows''. Or in other words, I don't want to connect to multiple web pages every time I open a browser, just the first time I log on for the day.
    I tried appending the web sites in the command line of a Firefox shortcut in my Windows Startup folder. The problem is that in this approach, you're limited to as many URL's as you can type in about 204 characters ('C:\Program Files (x86)\Mozilla Firefox\firefox.exe' uses up 52 of the 256 characters available in a shortcut).
    Is there a way to open more tabbed web sites than that?
    What would be cool is if there was something like a FFstartup.ini file or something, where you could provide a list of websites as long as you want, and it would open them all. So, the command line would look like:
    'C:\Program Files (x86)\Mozilla Firefox\firefox.exe' 'C:\Program Files (x86)\Mozilla Firefox\FFstartup.ini'
    ...and the FFstartup.ini file would look like:
    [Startup]
    'http://www.yahoo.com'
    'http://www.google.com'
    'http://www.firefox.com'
    etc...
    If there's no current way to do this, how would I make this suggestion to be developed?
    Thank you!

    Use a .bat or .cmd file to start Firefox if you need more space than the target line in a shortcut allows.<br />
    Separate the URLs with spaces.

  • Hello there! Does anybody know RadioWMPCoreGecko 5.dll. What is it and how can I remove it because it slows down my computer. Thank you.

    Starting my computer this morning I immediately was informed by Norton Security that RadioWMPCoreGecko 5.dll is safe. I don´t know this data and I want to remove ist because it slows down my computer. Has that something to do with Firefox? The Information of Firefox-Troubleshooting shows the following detail:
    Gecko/20100101 Firefox/8.0.1
    Can you help me?
    Thank you in anticipation.

    To whom it may concern here the answer I received today from Norton Support:
    ''I would like to inform you that the RadioWMPCoreGecko 5.dll files was downloaded as an update for the Firefox browser which runs in the background and Norton program does not have any control on the downloads till it is safe.
    If the download is safe, Norton program will notify you and will block, if file finds to be suspicious.''
    Now I know what it is, but nevertheless my PC is still rather slow.

  • Suddenly I can open only one Firefox window at a time. I can have multiple tabs in that window, but I can suddenly no longer open another window. What happened?

    Suddenly I can open only one Firefox window at a time. I can have multiple tabs in that window, but I can suddenly no longer open another window. What happened?

    Start Firefox in <u>[[Safe Mode]]</u> 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.

  • Firefox on my laptop will not allow me to open multiple tabs, how can I fix this issue?

    I usually use firefox and yesterday was downloading a photoshop program called gimp. all of a sudden after downloading it, firefox stops allowing me to open multiple tabs. I click on file and new tab, but it still will not work.

    The Ask Toolbar is causing that in the Firefox 3.6.13+ versions. Uninstall that extension.
    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

  • Firefox slows down when opening a site with animated gifs

    After updating to FF4, I find that whenever I try to open a page that has multiple animated gifs on it, firefox slows down tremendously. CPU usage goes up to 50-75% and all animated gifs are moving really slow.
    It's not only large animated gifs, but it also occurs on forums that have animated smilies. I never had this problem in FF 3.6 nor any other browser (IE, Chrome, Safari). If I start FF4.0 without any add-ons or plugins it does the same thing. Even with a fresh install. Does anyone have a solution to his problem? Since I can't use some of my favorite sites now with FF, without my pc slowing everything down.

    Disabling the hardware acceleration worked for me!

  • How can I actually open multiple tabs of the same site, instead of performing the new "switch to tab" action?

    For example, sometimes I would like to open multiple tabs of Google Maps to get directions to multiple locations, and I haven't found a way to do so without open a new instance of the browser. Thanks.

    This one colors tabs, but the author warns that it doesn't work with other tab-related extensions, so you probably need to keep searching for one that does everything you want:
    https://addons.mozilla.org/en-US/firefox/addon/colorfultabs/
    If you don't find a do-it-all extension, you can modify the tab titles with a userscript that is specific to that website. This is because the tab displays the text designated in the page as its title.
    You either could "hard code" the list of words for each of the pages, or you could have a script extract information from the page, for example, the first main heading, or some other predictable bit of data. The script then would insert your preferred wording as the title of the page and Firefox will show that on the tab.
    To see how that appears, so you know whether it would be useful, you could do this experiment:
    On a web page that has useless tab text, open the Web Console using command+alt+k (Windows: Ctrl+Shift+k). In the line at the bottom next to the caret, paste the following code and press Enter:
    document.title="Magic!";
    If you decide you want a script written for this, you could try the request forum on userscripts''.''org:
    [http://userscripts.org/forums/2 Ideas and script requests - Userscripts.org]
    Although some people offer small payments, that usually isn't necessary to motivate people to help.
    Let me give you a brief warning about that site, though: over the past year, a lot of popular scripts were duplicated and reposted with additional code that hijacks your Facebook account. Be cautious when installing scripts, check the reviews, make sure there are no references to Facebook.

  • Why is switching over multiple tabs in Firefox so slow? how solve this problem please

    My problem is just the slow switching over multiple tabs in Firefox. Each time I go to another tab it takes a while (sluggish), or you can say the ‘click’ on the tab takes time to happen. The rest Firefox is working perfect in speed.
    Don’t know how to solve it, followed all the steps on the MakeUseOf Firefox Speed Up Guide, still having same problem.
    please help me

    Hi tahas,
    Have you looked at our [https://support.mozilla.org/en-US/kb/firefox-slow-or-takes-too-long-start performance troubleshooting section]? There is a lot of good information in there that should help.

  • How can I set Safari to open multiple tabs when I open Safari?

    I was able to set multiple tabs to open when I open Safari in the past. However, I do not know how to do so now.
    Help!

    Hello sgertel,
    It sounds like you are asking about the OS X feature called Resume to have previous opened windows re-open when you launch Safari.
    Automatically re-open windows, apps, and documents on your Mac - Apple Support
    OS X Lion v10.7 and later include Resume, a feature that lets you re-open apps in the same state they were in when you last left them. For example, when you quit Safari, any webpages you're viewing are fully restored the next time you open Safari. 
    Is this not working for you?  Another thing I use is common folders in the Favorites bar where I can "Open in Tabs" at the bottom of the list.
    Take care,
    Nubz

  • Why can't I open multiple tabs in safari on my I pad air

    Why can't I open multiple tabs in safari on my I pad air

    Don't know since we don't know that you are doing.
    Are you tapping the blue + sign in the upper right corner of the Safari toolbar? That is what you do to open a new tab.

  • Firefox opens multiple tabs while clicking on "Manage account" under File- Account in Office 2013 opens the right Tab and another random URL-Tab

    I have office 365 installed. When I click on Manage Account under File->Accounts in office 2013, it opens 2 Tabs in Firefox.
    Tab1: https://office.microsoft.com/MyAccount.aspx?ver=15&app=winword.exe&MachineKey=02011-005-827906&fromAR=1
    Tab2: http://www.4a1.com/ ( which is random)
    The version of firefox is 24 and set as the default browser.
    Operating System: Windows 7SP1
    Already contacted Internet Service provider-Optimum, also the antivirus for security concerns but could not find anything from their end respectively.
    The issue occurs on Windows 8 laptop also.

    Thank you for your reply.
    (FYI: The above question was posted by a ''Microsoft Research Engineer'' and me since neither of us can figure out why this is happening. So the brain-bank on this is pretty big!)
    I scanned with all of the above scanners. (Thank you for the links!)
    I also scanned my system with Adaware, Super Antispyware, Norton Internet Security 2013, and Norton Power Eraser . . . and Kapersky v14 on the Windows 8 system)
    NONE of the scanners reported anything other than the usual trackers.
    Firefox was un-installed, re-installed, reverted back 4 versions ''and'' v3. Chrome shows the same result.
    The Windows 8 system was wiped and restored. Office 365 was immediately re-installed and showed the SAME behavior except that the "random" 3-character URL was different . . .
    . . . This extra Tab ''only'' shows up when I open any Office 2013 product to a New document or worksheet go to File>Account>Manage Account.

  • In the last week, Firefox slows down until it's unusable after about 30 mins

    As per the title. Firefox slows down until it is almost completely unresponsive the longer it is left open. When it is restarted, it works fine for a while but soon slows down a lot.
    I have about 50 tabs open and have never experienced this issue at all. I still have plenty of RAM free. When it's slow, even tasks such as opening menus or using the awesome bar slow down massively.
    I suspect a tab is at fault but can't think of an easy way to determine which one.

    I'm using the same antivirus for the last year and never had this issue before. Disabling antivirus doesn't help either.

  • Why when I open multiple tabs in Facebook, the tabs load very slowly and most times don't load at all?

    Why when I open multiple tabs in Facebook, the tabs load very slowly and most times don't load at all?

    The default of the pref network.http.max-connections has been increased from 30 to 256 in Firefox 6+ versions.
    You can try to decrease the value of the pref <b>network.http.max-connections</b> from 255 to a more modest setting like 30 as used in Firefox 3 versions.
