Firefox won't let me open more than one window at a time. how do i fix the problem

Firefox won't let me open more than one window at a time. It use to allow me to open multiple windows before but for no apparent reason it stopped. I uninstalled it and re-installed but I'm having the same problem. How do I fix the problem
== This happened ==
Every time Firefox opened
== several days ago

Start Firefox in [[Safe Mode]] to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
See [[Troubleshooting extensions and themes]] and [[Troubleshooting plugins]]
If it does work in Safe-mode then disable all your extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
You can use "Disable all add-ons" on the [[Safe mode]] start window to disable all extensions.
You have to close and restart Firefox after each change via "File > Exit" (on Mac: "Firefox > Quit")

Please help cannot open more than one window at a time.

Everything was working well but this morning I could not have more than one window (application or folder) open at a time.
As soon as I open one, the previously oppened one closes.
I tried restoring from Time Machine and also Lion altogether but this behaviour did not change.
I posted in the Imac forum as well but maybe this forum is more appropiate.
Thank you.

Another possiblity is that "Single Application Mode" has been set. This would be unusual as it normally takes a terminal command to set it. You can check by downloading the program TinkerTool from this site:
http://www.bresink.com/osx/0TinkerTool/download.php5
It's free and doesn't modify your system, just turns on or off the hidden options that are already there. Run it and look in the Dock tab and see if this option is checked. If so, uncheck it and click the relaunch dock button.

My 2009 iMac freezes and won't run more than one application at a time - how can I fix this?

Help! My iMac has been getting worse regarding freezing, especially when trying to open iPhoto. It will load slowly, and then I get the pinwheel of death for ever, until I shutdown and try over again. It usually takes several tries, and usually overnight. How can I resolve this issue?

First, back up all data immediately, as your boot drive might be failing.
Step 1
This diagnostic procedure will query the log for messages that may indicate a system issue. It changes nothing, and therefore will not, in itself, solve your problem.
If you have more than one user account, these instructions must be carried out as an administrator.
Triple-click anywhere in the line below on this page to select it:
syslog -k Sender kernel -k Message CReq 'GPU |hfs: Ru|I/O e|find tok|n Cause: -|NVDA\(|timed? ?o' | tail | open -ef
Copy the selected text to the Clipboard by pressing the key combination command-C.
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window (command-V). I've tested these instructions only with the Safari web browser. If you use another browser, you may have to press the return key.
The command may take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear.
A TextEdit window will open with the output of the command. Normally the command will produce no output, and the window will be empty. If the TextEdit window (not the Terminal window) has anything in it, stop here and post it — the text, please, not a screenshot. The title of the TextEdit window doesn't matter, and you don't need to post that.
Step 2
There are a few other possible causes of generalized slow performance that you can rule out easily.
Disconnect all non-essential wired peripherals and remove aftermarket expansion cards, if any.
Reset the System Management Controller.
Run Software Update. If there's a firmware update, install it.
If you're booting from an aftermarket SSD, see whether there's a firmware update for it.
If you have a portable computer, check the cycle count of the battery. It may be due for replacement.
If you have many image or video files on the Desktop with preview icons, move them to another folder.
If applicable, uncheck all boxes in the iCloud preference pane. See whether there's any change.
Check your keychains in Keychain Access for excessively duplicated items.
Boot into Recovery mode, launch Disk Utility, and run Repair Disk.
If you have a MacBook Pro with dual graphics, disable automatic graphics switching in the Energy Saverpreference pane for better performance at the cost of shorter battery life.
Step 3
When you notice the problem, launch the Activity Monitor application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Activity Monitor in the icon grid.
Select the CPU tab of the Activity Monitor window.
Select All Processes from the View menu or the menu in the toolbar, if not already selected.
Click the heading of the % CPU column in the process table to sort the entries by CPU usage. You may have to click it twice to get the highest value at the top. What is it, and what is the process? Also post the values for User, System, and Idle at the bottom of the window.
Select the Memory tab. What value is shown in the bottom part of the window for Swap used?
Next, select the Disk tab. Post the approximate values shown for Reads in/sec and Writes out/sec (not Reads in andWrites out.)
Step 4
If you have more than one user account, you must be logged in as an administrator to carry out this step.
Launch the Console application in the same way you launched Activity Monitor. Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Select the 50 or so most recent entries in the log. Copy them to the Clipboard by pressing the key combinationcommand-C. Paste into a reply to this message (command-V). You're looking for entries at the end of the log, not at the beginning.
When posting a log extract, be selective. Don't post more than is requested.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some personal information, such as your name, may appear in the log. Anonymize before posting. That should be easy to do if your extract is not too long.

I just upgraded to Mountain Lion. Now I can't open more than one website at a time. When I do the first site, minimized and in the dock, is taken up by the second one.

I just upgraded my computer from Snow Leopard to Mountain Lion. I used to be able to have as many websites open as I wished. Now when I open a website and minimize it, it minimizes and moves to the dock just like it used to do. But now when I open a second website, it takes the place of the first one down in the dock that was minimized. I can't open more than 1 website at time now.

There is something basic going on that unfortunately has me stumped.
Before you spend the $20 please try creating a new user, for testing purposes:
Creating a temporary account to isolate user-specific problems: Isolating an issue by using another user account
That is easy enough to accomplish. If Safari and the Dock behave as you expect while using that account, it will help determine the cause. Please report the results of this test.
Delete the temporary account after you finish testing.
Many of those features I mentioned are new in Mountain Lion, and represent a significant change from Snow Leopard. Though you should certainly continue to use your Mac the way you have been accustomed to using it, you may find using Mountain Lion's new features advantageous. If you are fortunate enough to have an Apple Store nearby, you would benefit by taking advantage of Apple's many free workshops: https://www.apple.com/retail/learn/
Otherwise you may find yourself spending the $20 often. The help available here is often better than Apple's. It is not always correct, but it is always free.

Why am I unable to open multiple tabs in the browser? It all of a sudden refused to let me open more than one at a time.

While on the internet, I tried to open two tabs, but it won't open any more for me. I tried right clicking and opening that way, but it won't let me. I removed Mozilla Firefox from my computer and re-downloaded it, but it still won't let me open more than one tab. It's happened to two of my computers now, and nothing works for either one except opening in safe mode every time.

Start Firefox in [[Safe Mode]] to check if one of the add-ons is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).

Why won't Garage band let you open more than one project a time..

Why won't Garageband let you open more than one project a time???? If thats the way its is set up...that is really lame. Even the worst audio programs allow you to run a few projects at a time.
I recorded a gig the other night... then I dumped the whole set on to one track. When I wanted to copy and paste individual songs into their own project it made me close the current project. Is there a way around this???
Joe

Heh, heh. Yes, this is true. Alas... BUT, if you want to compare one project with another, it can be done.
There is another advantage to making another copy of GarageBand. I created a copy and call it "GarageSymphony" that contains all my instrument specific icons for orchestral packs. This way I do not mess up the GarageBand application.
I would not be surprised to find multiple windows become available in GB4. I was more than pleased to find this change in iMovie 6.

Multiple addons will not work, firefox will not open more than one window

Here's the problem: when certain addons (such as Morning Coffee, Fire.fm, Thumbstrips, Colourzilla, and others) are enabled on my firefox, it won't open more than one window. Additionally, some of these won't work at all (the first three listed). I know similar questions have been asked before, and the answer given was to disable the add-ons in question. However, I would love to actually be able to *use* them.
Anyone know how I might be able to fix things so that the addons work, and firefox isn't disabled in any way?
== This happened ==
Every time Firefox opened
== A while ago (I disabled the addons), and again today

There's a few extensions that are causing a problem like that. See this:

After i downloaded Firefox 7, I cannot open more than one page at a time. I have done everything you suggested about ad-on, etc. Other people are having problems. Can I get reall help with this or should I just reload Firefox 4?

Firefox 7 is a dud. Cannot open more than one tab at a time, will not open additional pages. Nothing you suggested has worked.
Can I take down Firefox 7 and reload Firefox 4?
I need to talk with a live person! I am real disappointed with this.

Firefox will not open more than one window and upon restarting will not open the previous tab and refuses to open bookmarks

Firefox does not open more than one window. I can open plenty of tabs, but not more than one window. Upon closing firefox and trying to restart the browser will not open and needs to be closed through windows task manager. Upon trying to re-open Firefox I receive the 'oops this is embarassing , firefox cannot re-open your tabs" message. When I click on "new session" the bookmarks do not load. It is becoming very frustrating as I am a student and often do lots of research on the web while using lots of open windows.

Or, just intall by new printer but do not Delcare it as the Default printer, I guess in this instance there would be NO default printer?
You may not even have the problem!
Have you installed the new printer yet?
There are many more people who don't see it happen than those who do.
PS: there is always a default printer.

Copy the songs to a computer that is running iTunes, add those new tracks to the current library, and then synch those tracts to the iPod.

Cannot open more than one window with Firefox

I've been having this problem for a couple of weeks, now, and I've run out of ways to try and fix this.
One day, after starting my computer up, I opened Firefox. No big deal, everything looks fine, tabs are working, etc. Then, when I went to open a second window, nothing. The first window still works fine, I can open tab upon tab, but it just won't open any more windows.
As much as I'm a fan of the browser tabs, I still prefer to have them spread out over more than one window.
I've read through a ton of different troubleshooting walkthroughs and whatnot, reinstalled three or four times, restored settings, but nothing works.
Well, not entirely, I guess. Here's the part that I can't quite figure out. When I disable every single addon, Firefox works just fine. I've done the checking down the list, trying to single one out, but it's *any* addon. Even something as simple as a dictionary search ([https://addons.mozilla.org/en-US/firefox/addon/68/]) causes this to happen.
I've checked with an older computer with an older version of Firefox, and it still seems to work fine with addons enabled, so I'm wondering if this is an update issue?
Would reverting back to a previous version of Firefox solve this, and if so, where would I be able to find downloads for a previous version?
So, like I said, I'm at a bit of a loss here. Sort of at a crossroads for trying to figure out what to try next, so I'm hoping someone a bit more knowledgeable can help steer me in a direction.
Edit: I just noticed that the posting includes system information with my question. I should clarify that I'm posting this from an older computer with an older version of Firefox. On the computer that I'm having this issue with, I'm using the newest version of Firefox (3.6.8).

Some old posts indicate the following add-ons have caused the problem of not being able to open a new window in Firefox in the past. If you have any of them you might want to disable or uninstall them to see if that is causing your problem.

You are using an out-of-date version of Firefox. Unless you have a reason for using that old version, you might want to consider upgrading.
*The Firefox version series 3.0.x is no longer being supported or updated, even for security issues.
*The last version in the 3.0.x series was 3.0.19 which was released 03/15/2010.
*You are using version 3.0.13 which was released 07/31/2009.
Consider upgrading to the current version, Firefox 3.6.8. Firefox 3.6.9 is scheduled to be released in a few days and the new Firefox 4 will be released later this year or early next year.

Can't open more than one window in PS-CS4 - Snow Leopard

Just got CS4 and have anew iMac.
I tried to open more than one image in PS and it won't let me.
It simply replaces the image that's currently open. If I close that window,
the first image will appear in the window. This can't be right. What's happening.
Thanks

Rick,
The documents aren't replacing each other - what you're experiencing is the new "tabbed windows" feature in CS4. Next time you try to open 2 documents, look at the bottom of the "Window" menu and you'll see that both documents are actually open. Then look at the window's title bar and you'll see two "tabs", similar to what some web browsers do with multiple open windows. Just click on the tab of the window you want in the foreground.
If you'd prefer to go back to the CS3 method, go to "Preferences>Interface" and un-check the "open documents as tabs" checkbox.

Can you use or have open more than one app at a time on iphone 6 plus?
