Firefox doesnt load an image when *lots* of tabs are open

Hi,
An old website I created has a problem displaying a very large background image when *loads* of tabs are open (which makes me think its something to do with memory).
An example page of the site in question is:
http://www.southbankcentre.co.uk/about-us
The white background image (which is super large for reasons not to discuss now) will show fine when, say, up to 10 tabs are open. However, if you have loads and loads of tabs open, this image doesn't display/render (even though firebug says it has).
Some info about the image:
http://www.southbankcentre.co.uk/sites/all/themes/southbank-centre/images/template-3-col.png
79.6kb
940px by 23000px (super huge I know)
The problem is when it doesnt load, the copy is hard to read (as you can imagine).
This doesnt seem unique to my computer. It happens to other peoples firefox browsers (and they have slightly different versions and different plug-ins).

I'm not having any problems on that page with over 80 tabs open and the number of tabs shouldn't matter.
Did you check if you can reproduce it with a clean new profile without extensions?
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).
* Don't make any changes on the Safe mode start window.
See [[Troubleshooting extensions and themes]] and [[Troubleshooting plugins]]

High memory usage when many tabs are open (and closed)

When I open Firefox the memory usage is about 70-100 MB RAM. When I'm working with Firefox I often open 15-20 tabs at once, then I close them and open others. Memory usage increaes up to 450 - 500 MB RAM. After closing the tabs the usage usually decreases, but after sometime. It starts decreasing very slow and never comes back to the level from the beginning. After few hours of work Firefox uses about 400 MB RAM even if one tab is open. First I thought it's because of my plugins (Firebug, Speed Dial, Adlock Plus) but I've checked it and it's not. I reinstalled Firefox but the problem occurs as well. I'm not sure if it's normal. Could you help me, please?

Firefox won't launch - I get an error message saying that firefox has to close

It tells me it's sending a message to firefox but as I can't log in it won't do this.

I've just (finally) managed to fix this problem today. I checked the Apple Support forums, and it seems a lot of people are having the same problem.
I rang the Apple Support line, and the very helpful man (thanks Alan!) talked me through it stage by stage. If you go to the following page on the internet: http://support.apple.com/kb/TS5376 it takes you through the process. WARNING - it takes a little time!
Basically, the first thing you have to do is go to your Program Files and double click on your iTunes folder. There'll be a number of files with the suffix .dll - you need to move all the .dll files from that folder to your desktop - you can simply click and drag them on the desktop..
Next, uninstall iTunes - go to Control Panel / Add/Rempve Programs and when the list comes up remove iTunes. This will take a few minutes... Then reboot your computer.
Next, go back to Control Panel / Add Remove and Remove - IN THIS ORDER -
Apple Software Update
Apple Mobile Device Support
Bonjour
Apple Application Support
Reboot again!
Next, check in your Program Files that the iTunes folder is completely gone - if it has, great: if it hasn't, right-click on the folder and press Shift and Delete - it will say "Are you sure you want to completely remove the folder "iTunes"? Click on "Yes".
Reboot!
Then go to the iTunes download page and voila! It should download iTunes without any problems... well it did for me.... Good luck!

Firefox crashes when too many images are opened

Okay, so, a problem that appeared in 4.0 for me, and hasn't gone away ever since.
The problem is basically summarized in the short description - whenever too many heavy images are in the browser's tabs simultaneously, it slows down to a halt; then sometimes as I scroll it fails to redraw the page, with black non-redrawn area increasing as I scroll and disappearing as I change tabs back and forth.
After a dozen seconds of such sad behaviour, the browser crashes.
Sometimes, however, things go better. And it just crashes.
The problem can be easily replicated with Save Images extension, say, on any photo hosting, or by opening
http://danvolodar.livejournal.com/friends/big_picture
It should be noted that 3.6 never had that problem, and opened pages where I aggregated thousands of images, - slowly, of course, but it ''did'' work. 4 and 5 do ''not''.

Go to the address '''about:crashes''' and tell us your latest crash IDs. We can then look at the data specific to your crash and have a better idea of what is causing the problem.
Or you can go to '''Start''' and type in the Vista search box '''%APPDATA%''' then click on '''Roaming''' then go to '''Mozilla>Firefox>Crash Reports>Submitted''' then open the .txt files and copy the Crash report ID that starts with '''bp-xxxxx-xxxx'''

I can't get firefox to open. Try creating another profile as suggested in another answer, and it says that firefox has crashed, how do I get firefox working?

I had to restore my computer to a previous restore point. When I tried opening firefox 4.0, nothing happened. Frustrated, I tried removing the program, but ran into the same problem: nothing happened. I went to Processes in Windows Task Manager, and firefox.exe was not running. Tried using the suggestions to create another profile, and entering the command into run brought up an error saying that firefox has crashed.

OK - undo the changes you made to DEP.
Open Firefox - take a screenshot of any message that appears and post back here

Firefox constantly runs in the background even when closed

Hi
I have Firefox 3.6.8 running on Windows Vista.
I have found that Firefox constantly runs in the background even when i have just booted up the computer or when i have closed it.
Firefox seems to constantly run with 5000-20000 K bytes in the memory.
When i have Firefox running to look at webpages, there are two processes running. When i close Firefox there is one process running. If i end the process using the task manager, it only takes seconds before it starts to run again.
I know this isnt normal because i keep a good eye on the processes running on my computer. So unless the latest version of Firefox requires this process running all the time, it looks like i have a probably.
Ive scanned my computer with zonealarm, avast, superantispyware and spybot to scan my computer for viruses. One of the pieces of software found a virus and it deleted it successfully.
Im not too sure if this is a virus that is hiding in my system or whether its part of the latest version of Firefox.
Firefox isnt showing the usual signs of a virus. As in it doesnt try to redirect me to random websites and it doesnt try to get me to download something.
I hope someone can help me please.
Rob

After talking to someone very helpful on the live chat support.
It appears like i have a virus that is very good at hiding from detection from anti-virus/spyware software.
No idea what intentions the virus has as its not showing any sort of virus like behaviour.
I called the old installation a different name and closed the Firefox process. A few seconds later, instead of a Firefox process starting again a different executable started.

I'm getting popup notices that Firefox has a problem, and Windows is looking for a solution; then it closes Firefox and says Windows will let me know if it finds a solution. No crash report window comes up.

Firefox is my default browser on my new laptop, with OS Windows 7. I've now had several instances where a Windows popup comes up saying Firefox has developed a problem and may have to close. It also indicates Windows "is looking for a solution to the problem." No solution is found, however, and Firefox is forced to close, with the happy notice that Windows will let me know if it finds a solution to the problem. If there is any tech data on the crash, I'm not sure where to find it, and no Firefox crash report window comes up. I thought it was an anomaly the first time, but this has now occurred at least 4 times in the past several days.

I have iphone 4 os 7.04, tried updating to 7.1, but continously shows error that I dont have working internet connection, though I have one and tried via wifi and 3g same error comes. The update has been downloaded, agree pressed but no further??

I have iphone 4 os 7.04, tried updating to 7.1, but continously shows error that I dont have working internet connection, though I have one and tried via wifi and 3g same error comes. The update has been downloaded, the page shping license agreement comes. As soon as I press agree, it asks me to wait for verification and then this error that there is no working internet connection comes, even though I have one and it works fine

Try these steps as needed:
Reset phone: press both the home and power buttons, releasing when the Apple logo appears
Settings > General > Reset > Reset Network Settings. You will have to re-enter WiFi passwords
Connect phone to iTunes on your computer and update using iTunes

When I try to update to Itunes 11 I get an error message saying that Itunes has an invalid signature and wont be installed. I use Windows 7.

Everytime I try to update to Itunes 11 I get an error message saying that Itunes has an invalid signature and can't be installed? I have tried to install it two times and get the same message each time. Any solutions to my problem?? Those who have installed ITUNES 11 is it hard to work with? maybe im lucky it wont update?? I don't know.

That suggests that the installer is getting damaged during the download.
I'd first try downloading an installer from the Apple website using a different web browser:
http://www.apple.com/itunes/download/
If you use Firefox instead of IE for the download (or vice versa), do you get a working installer?

After I exit Firefox, I get a pop-up message that Firefox has stopped working.

After I exit Firefox, I get a pop-up message that Firefox has stopped working. I have to click to close the program, or search online for a solution to the program, then close.

Everytime I close Firefox it gives me the message box that firefox has crashed

I close firefox with the X like I close all of my applications but every time I close it I get a popup box saying that firefox has crashed do you want to send a crash report and I can type in what happened. Then I can choose to close firefox or restart it.

I uninstalled Firefox once, reinstalled it and it ran. I had a problem so I did it again. Now it will not run and I get an error message saying that firefox is running and you can only run one at a time. I can't figure out what is running.

Because of a problem, I uninstalled Firefox once, reinstalled it and it ran. I had a problem so I uninstalled/reinstalled it again. Now it will not run. I get an error message saying that firefox is running and you can only run one at a time. I have uninstalled multiple times and can't figure out what is running. The is only one Firefox installed and it is not open. What does this mean and how do I fix it?

If you use ZoneAlarm Extreme Security then try to disable Virtualization.
