When I close firefox it doesn't close. I go to reopen it and it says that it is already running. I have to use task manager to end process to close it before i can log back on.

After browsing and I close Firefox it appears to close.
However when I go to reopen it later I get a message that Firefox is already open and I need to close it. The only wany I can close it is by using Task Manger to end process.

Must be the "hang at exit" problem. You already know how to do Step1; now just determine which Add-on (Extension or Plugin) is causing the problem.

Sometimes I have to use Task Manager to 'end process' Firefox before I can open it (not shutting down cleanly from previous use)

Question seems self-explanatory

See "Hang at exit":
*http://kb.mozillazine.org/Firefox_hangs
See "Firefox hangs when you quit it":
*https://support.mozilla.com/kb/Firefox+hangs

When re-starting FF, after a close, FF says that there is FF already running. Have to use task m. to close firefox.32*exe.

after using task manager to close the firefox.32*exe process, then FF will restart properly. Doesn't seem to happen if the laptop is powered off.

Why do i have to use task manager to end firefox even after i close the website

every time i go to close firefox, i use either the X or file exit.
then i go to the icon to launch the program (firefox) i get a pop up that tells me firefox is still running to maybe restart my computer.
the only way i can override this is by using "task manager" look for the icon and end the process.
then i can reopen the browser

Use "Firefox > Exit" (Windows: Firefox/File > Exit; Mac: Firefox > Quit Firefox; Linux: Firefox/File > Quit) to close Firefox if you are currently doing that by clicking the close X on the Firefox title bar.
In case you are using "Clear history when Firefox closes", try to exclude the clearing the Cookies

I have the problem described in /forums/knowledge-base-articles/704725. (Firefox is already running but not responding). My only solution is to use Task Manager to end the firerfox process. I am the only user and there are no other profiles on my system

Occasionally I have the problem discussed in /forums/knowledge-base-articles/704725 , Firefox is already running. My only fix is to use Task Manager to end the firefox process. At such tmes, I have no other instances running.

This is not a cure but will make it easier if Firefox locks up.

Can't close indesign. have to use task manager repeatedly.

when closing out indesign CS5 it shows a few popups in the upper left corner really fast (it does it when i save now in illustrator as well) and then doesn't close. i have to open task manager where it is listed as "not responding" and close it every time. i have restarted and run defrag and disk cleanups and it doesn't help.

when i turn off the auto-activation feature it seems to be shutting off
properly. it was set to turn off fonts upon closing so i bet that is
what was causing issues. i turned it back on and indesign closed fine so
i'm not sure if the issue is fixed or not. turning it off seems to have
stopped the weird popups in indesign and in illustrator when i turn it
off in that as well. so it appears to be the suitcase fusion 3
auto-activation causing problems.
as for the forums, when logging back into adobe forums it tells me i
need to select a screen name even though i have one and won't let me
continue since mine is marked as being used. so i still can only reply
using email. i have attached screenshots anyway just in case it might be
something else.

I have lost my photos/videos when i imported from my ipad 2 to my new imac latest version and it's not reading the files. I have downloaded iMac library manager and can see them. can someone shed some light please ?

i have lost my photos/videos when i imported from my ipad 2 to my new imac latest version OS X 10.8.4
and it's not reading the files. I have downloaded iMac library manager and can see them. when i go back into iphoto i'm getting the following message :
Do you want to switch the current iPhoto Library from “iPhoto Library.photolibrary” to “iPhoto Library.photolibrary” and relaunch iPhoto?
I don't know what to do - please help !!!!
can someone shed some light please ?

So it appears you have only one library on the hard drive. Apply the two fixes below in order as needed to that library:
Fix #1
1 - launch iPhoto with the Command+Option keys held down and rebuild the library.
2 - run Option #4 to rebuild the database.
Fix #2
Using iPhoto Library Manager to Rebuild Your iPhoto Library
1 - download iPhoto Library Manager and launch.
2 - click on the Add Library button and select the library you want to add in the selection window..
3 - Now that the library is listed in the left hand pane of iPLM, click on your library and go to the Library ➙ Rebuild Library menu option.
4 - In the next window name the new library and select the location you want it to be placed.
5 - Click on the Create button.
Note: This creates a new library based on the LIbraryData.xml file in the library and will recover Events, Albums, keywords, titles and comments. However, books, calendars, cards and slideshows will be lost. The original library will be left untouched for further attempts at fixing the problem or in case the rebuilt library is not satisfactory.

When I log off of Firefox, do something else, and then want to get back on Firefox it says that it is already running and have to close the old Firefox out. How do I do it? Now, I'm restarting the computer. Is there an easier way? Thanks Steve

I x off Firefox and work on MS Pub or Word, perhaps my email. If, for some reason I want to go back on Firefox, a box comes up and says it's already running - to close it and restart Firefox. I can't find where to close it? If I could re-open it, that would be fine, but to close it - there are no tabs, icons etc. So, I simply restart the whole computer and begin again. That's a long way round the barn!
Steve

Check the task manager (ctrl + shift + esc) and look for firefox.exe in the processes tab. If it's running, close it.

Why do I have to use task manager to close FF after I exit FF?

I use Firefox close it like normal. If I start it again it will not open and I get and error message "firefox working with other program, try closing firefox".
I then open the task manager, end process, Firefox*32.~.
I thought maybe it could have been a plug so I disabled all plug-ins. Restated FF it went to google/FF home page. I closed firefox at the X. Opened the task manager and it was still running in the end process tab.

Use "Firefox > Exit" (Windows: Firefox/File > Exit; Mac: Firefox > Quit Firefox; Linux: Firefox/File > Quit) to close Firefox if you are currently doing that by clicking the close X on the Firefox title bar.
In case you are using "Clear history when Firefox closes", try to exclude the clearing the Cookies

Why is Lion installed on external HDD and iMac says that Lion is already installed when it is not?

I went into the Apps store then logged in to confirm that I wish to pay for the Lion upgrade from Mac OSX v10.6.8.
The downloaded 3Gb installation file went into my Applications folder after a few hours:
This installation application is still in the Application folder of the iMac.
During the upgrade / installation, I got the following message, saying that the installation can't go in the HDD of the computer I was working on (ie. the iMac's Macintosh HD). I had no choice but to select the external HDD (WD-1T) as the installation destination, which proceeded very quickly.
When the installation was complete, the iMac rebooted into a fresh Lion installation, running off the WD-1T! I can see all my old files on the Macintosh HD, as if that HDD was the external HDD!
If I disconnect the WD-1T upon rebooting, I am back to Snow Leopard, running from the iMac's Macintosh HD. If I go the App store, it tells me I have already installed Lion on the iMac (when it is not the case)!
When I go to my MacBook Pro (currently on Snow Leopard and not part of from the above installation), I see that Lion is purchased but not installed. If I click INSTALL, it starts to download what the iMac had earlier downloaded (the Install Mac OS X Lion.app is still sitting in the Application folder of the iMac).
Question:
Can anyone shed some light why this happening and how to get Lion onto the iMac?
How to install Lion on the MacBook Pro without re-downloading the software?

I would say it is related to the purchase date. FaceTime is included in 10.6.6~8 OEM discs.

Firefox crashes on shutdown, shows not responding, must use task manager to end task, windows says problem is with container.exe file

whenever i decide to shut down firefox, i click on the x in the first tab and it will not shutdown the program. i must go to task manager to close the program. i get an error report that says there was a problem with add-on container.exe. i have looked in my add-on list and i see no container.exe there. where is it coming from and how do i get rid of this problem. i have even tried to shutdown the program with the x in the upper right corner and it does the same thing. i have recently updated firefox and it still does the same thing.

I've had issues with Firefox hanging in memory even if I try to remove it using the Windows task manager's "End Process" button. My only alternative is to force a reboot on my PC.

Since upgrading to Firefox 7.0.1 I've noticed the abovementioned problem. I usually have a couple of app tabs with GMail information on them (two different e-mail accounts, one of which is just the contacts page and the other is the inbox and one tab with a GMail calendar for one of the accounts) and my home page, which is Google News. While I cannot say for certain that it is related to multimedia streaming, it does appear to happen after I play some kind of video file like the videos for The Daily Show with Jon Stewart. My O/S is XP Pro SP3, my PC is a Dell Inspiron 700m w/2GB RAM. The Add-Ons that I have, as far as I can remember, are AdBlock Plus, Tab Mix Plus, WOT Safe Browsing Tool, and Download Statusbar along with the usual Java stuff. My Adobe plug-ins are always updated whenever I get an update message.

Firefox will download some of the new messages. Hang and eventualy say no new messages. Run again and several messages will download and mess up again.

This happened some time after I cleaned up and deleted many old emails. The reason I did this is the system was really slow downloading messages.
Shortly after that it would say I had 300 messages download a random number. 1,50,200 etc then stop. Saying no new messages.
My server provider is ATT Uverse. I checked the mail server changing to the latest recommeded settings for the sbcglobal.net domain. Problem is still there.
I configured Outlook on my computer for the first time. Outlook works perfectly. Thunderbird does not.
I first noticed the problems a couple of weeks ago. Got worse after cleaning up old emails late last week.
I have compacted all the folders and rebuilt the index. Tried safe mode worked once second try same problem.
Stopping MCaFee did not help ether

Turning off Real Time Email Attachment scanning fixed the problem.
I turned the Mcafee Fire wall back on and the plugin . Will experiment to see what if it is just the Attachment Scanning or if the other parts need to be disabled also.
Thank you.

Firefox won't open. Not showing in Processes window on Task Manager to end process. Recently installed ZoneAlarm security suite. ???
