Why do 3 instances of Firefox open at the same time?

Every time I start up Firefox, 3 different instances of Firefox will open at the same time. Do I need to uninstall it and start over? I don't know why this is happening. When I open IE8 only one page opens; but when I open Firefox 3 tabs open at the same time.

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.

* 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).

My hus why cant I have two browsers open at the same time like i did with 3.6

My husband and I both use facebook. I used to be able to open one browser under his name then another under mine. Since i downloaded the new ff4 I can only get on one at a time and it signs me out of the other. How do I fix this!!!!!

You can look at one of these if you want to sign on with different identities at the same time. 
Use the "Firefox 4? Try Multifox 2 Beta 1!" link.

Is it possible to have 2 profiles open at the same time? instead of having to open and close firefox everytime you want to switch.

I have several profiles and was wondering if it is possible to have more then one open at the same time? At the moment I am having to close the current firefox browser to open up a different profile.

Why does mountain lion "bunch up" all my microsoft office documents that I have open when I hit f3? When I had snow leopard for example, if i had 4 or 5 different microsoft office documents open at the same time I could hit f3 and easily pick one of them

Why does mountain lion "bunch up" all my microsoft office documents that I have open when I hit f3? When I had snow leopard for example, if i had 4 or 5 different microsoft office documents open at the same time I could hit f3 and easily pick one of them.
Notice how in the photo, I can't identify which MS office document I would like to switch too. Perhaps since the Dashboard and Desktop windows are at the top of my screen now Apple doesn't let you have all the applications take up the full screen and be sized individually so that you can have a better idea on what to pick.
I like the idea of grouping to an extent... If you have a bunch of random things it was hard for me to decifer between what was safari, chrome, or word. But now that they grouped them like this, if you have multiple pages of one program running, you can't switch between those pages easily like before.

If I wanted to open any of my Applework documents I had to open them one at a time and resave them with pages. This could take weeks.I have 1000s of apple work documents.
You don't have to open and re-save every AppleWorks document you have right now. Just wait till you need one, then do it. The documents aren't going anywhere.
Am I dealing with Microsoft? This was a BIG surprise to me that Apple would release an OS without testing all programs.
Frankly, it is not Apple's responsibility to ensure compatibiltiy with every piece of software available for OS X. That is the responsibility of the software vendor. Lion has been available to developers for several months before it's release, so Microtek had plenty of time to update their software. Yet they did not. How is that Apple's fault? I think Apple was very generous to give you a refund for Lion.
I'm not trying to belittle your frustration but I do think your ire is misplaced.

How do I open multiple Firefox home pages? I want all of my different Firefox email accounts open at the same time. I recently upgraded to Win7 and now I have to close and open Firefox to access another email acount!

I want 3 separate, distinct Firefox home pages for each of my 3 email accounts to be open at the same time.

Questions are typically followed by a question mark. My answer answered your question.
Firefox doesn't do email, so there are no "Firefox email accounts". If you are accessing "email" with Firefox, you are using web mail. Some web mail services don't allow for direct access, they want their users to access their email from a "portal" or "main" page and will re-direct any attempt to load an "internal" web site page back to the main page.
As far as loading 3 different web mail accounts at the same time, if they are in the same domain it won't work on Firefox without a Firefox addon. http://br.mozdev.org/multifox/
IOW, if those three email accounts all with Yahoo, without that add-on you would have to logon to each email account separately and log out of the first before logging into the 2nd. Then log out of the 2nd before logging into the 3rd. Firefox isn't capable of having multiple session cookies for simultaneous logon's to the same server. That add-on provides that "multiple sessions cookies" feature.

When i have 4 or 5 browser windows open at the same time, sometimes they get grouped into one tab and i can not ungroup them. why does this happen?

4 or 5 browser windows open at the same time. Tabs are down in the control bar. every now and then they just combine into one pop up. can't undo and very annoying. Have to close all out and start over.

This can happen if you drag a tab slightly down in the browser window while clicking.
Firefox has a feature called tear-off tabs
You can detach a tab from the current window and open it in a new window by dragging a tab in the browser window.
You can also do this via the right-click context menu of a tab: Move to New Window
You can drag that tab back to the tab bar in the original window to undo that detaching.

I run Firefox with at least twenty tabs open at the same time. Version 23 (and later versions) load the tabs MUCH more slowly (2 mins rather than 15 secs). HELP

I run Firefox with at least twenty tabs open at the same time. All versions of Firefox newer than version 22 ) load the tabs MUCH more slowly ( approx 2 mins rather than merely 15 secs). HELP!!

Start Firefox in [[Safe Mode|Safe Mode]] to check if one of the extensions (Firefox/Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Firefox/Tools > Add-ons > Appearance).
*Do NOT click the Reset button on the Safe Mode start window.
*https://support.mozilla.org/kb/Safe+Mode
*https://support.mozilla.org/kb/Troubleshooting+extensions+and+themes
Also check your security software.
You can use the Network tab (the one at the right in the menu) in the Web Console (Firefox/Tools > Web Developer;Ctrl+Shift+K) to check the server response (left-click an entry) see if that is the problem (reload via Ctrl+F5 to bypass the cache).

Not able to keep two OEM ( 11g) Database Console open at the same time.

Hi Gurus,
I am running into issues when I try to keep two instances ( TEST and PROD) of Oracle 11g on the same server open in OEM Database Console.
The issue is when i try to loginto the 2nd OEM database control page on a new tab of internet Explorer ( when the Ist DB console is open in another tab), it close the first one and open the 2nd instance.
Also trying opening two seperate IE sessions ( without tabs) , still its logs out the Ist instance.
Any idea why this is happening and How could I have both the OEM DB consoles open at the same time. please advice
Thanks
Sheik

Sheik,
There are two types of Database Enterprise Managers, one is Database Control(free tool) and another is Grid Control(paid tool). The one that you are using is a free tool with the limitation that at one time, there can be only one database which can be managed by it. For each database managed by DBC, there is a different port number assigned and only when you use DBC at that specific port number, you can manage the said database. You can check the initially assigned port numbers for the databases in the file *$OH/install/portliist.ini*. You can have a read about about it over here,
http://download.oracle.com/docs/cd/B28359_01/server.111/b28301/em_manage002.htm#sthref97
The Grid control can manage all the databases under one window only but its a paid version of EM so it can't be used without a proper license.

I want to open a folder in a separate window by clicking on it. For some reason when I click on a folder it just replaces the one I was just in. I want them both to be open at the same time without having to go through several steps.

I want to open a folder in a separate window by clicking on it. For some reason when I click on a folder it just replaces the one I was just in. I want them both to be open at the same time without having to go through several steps. Old apple operating systems made it easy to have several folders open at one time.

Eric, thanks that works but seems like an extra added step also to do it that way. I've got to move and organize a ton of files and I'm looking for a easy way to get this done. I could also open the folder into a separate tab and then drag the tab out so it becomes an open window but thats a lot of fussing around also with extra steps. Not sure why these newer operating system seems more confusing and less user friendly than what they used to. In the past I could just click on any folder and it would open in a separate window making it really easy to copy or move files from one place to the other just by simply dragging them from one window to the other. Seems like I'm going through several extra steps now to do a simple task.

I am doing two people's jobs and I need to use two separate log-ins on the same website. How can I keep both log-ins open at the same time. Everytime I switch tabs I have to log in again.

Lightroom quits when Photoshop CS4 is open at the same time

When I have Lightroom open at the same time as Photoshop CS4 I get the message Lightroom has encountered a problem and has to shut down. I am running the latest version of Lightroom using a PC with XP professional 64 bit. Also occasionally Lightroom reverts back to an old catalogue. Does anyone else have these problems?

Just FYI, Lightroom is not supported on XP 64 bit. This might be one of the reasons why. You might need Vista or 7. I do know many people still run it on XP 64 though.

Can I have mail and contacts open at the same time

I really want to be able to have one or more iCloud Apps open at the same time; for example, I may be looking up some info on a contact or in calendar in order to mail someone. At times I have just opened a different tab, but it seems that iCloud then gets messed up.
I am running Windows 7 at work and the latest version fo Chrome.
Any help would be greatly appreciated.
Bryan

Hi,
I don't know in Chrome, but in Safari (pc or mac) you can open icloud.com twice on two different tab or windows and open one with contact and the other in Mail without messing up. What kind of mess to do you experience?
There is no other options to do what you want to do. You need to click on the little top cloud to switch from one to another.
Beside, I don't understand why even 2 open tab would help more than having to switch via the cloud icon. I may need to cut/paste some info from contact or calendar from time to time, but switch via the cloud icon is not really painfull.

Why do 3 instances of Firefox open at the same time?
