When I close Firefox and re-open it, all previously cached images are NOT loaded from cache. Why?

I have a website. Google recommended page-speed and I had previously installed fire-bug. I open Firefox and inspect my website - the home page loads in approx 2 seconds. I may follow a variety of links and all images ( expiry life of 3 months ), css and js files ( expiry life 1 hour ) are cached so that each screen loaded takes less time. If I close firefox get on with other work and then re-open it, its like the images were never cached - what's the point of caching if its ignored?

Make sure that you do not use "Clear Recent History" to clear the 'Browsing History' when you close Firefox or use cleanup software that clears session data (sessionstore.js)

If you use [[Clear Recent History]] in Firefox 3.5 and later or [[Clearing private data|Clear Private Data]] in Firefox 3 to clear the 'Browsing History' when Firefox is closed then restoring tabs from the last session ("Save & Quit" or "Show my windows and tabs from last time") doesn't work.

Images are not loading from initial domain when using a cdn

Hello, i have a wordpress website on which i set the w3 total cache plugin with a cdn, the cdn is MaxCDN and is configured to not serve images but only css & js & font files. Because i configured the cdn not to serve images, the images in css files have the src as absolute path, path which point to original website domain, something like this: background-image: url("http://www.originaldomain.com/images/back.jpg");, the css file is served from the cdn like this: http://cdn.originaldomain.com/css/style.css . So the problem is that firefox refuse to load the images referred in style.css file, images which probably appear to be in another domain. If i try to load the images directly in browser, using address bar, they are loading ok, but on loading from css file i got a http error 500 (acording to firebug). The same website is loading ok in other browsers: ie7/ie8/ie9, opera, safari and chrome. Can anyone help me to solve the issue?

'''Try Firefox Safe Mode''' to see if the problem goes away. Safe Mode is a troubleshooting mode, which disables most add-ons.
''(If you're not using it, switch to the Default theme.)''
* You can open Firefox 4.0+ in Safe Mode by holding the '''Shift''' key when you open the Firefox desktop or Start menu shortcut.
* Or open the Help menu and click on the '''Restart with Add-ons Disabled...''' menu item while Firefox is running.
''Once you get the pop-up, just select "'Start in Safe Mode"''
'''''If the issue is not present in Firefox Safe Mode''''', your problem is probably caused by an extension, and you need to figure out which one. Please follow the [[Troubleshooting extensions and themes]] article for that.
''To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.''

Firefox is not opening the "Show All History" Window, images are not loading and part of the new tab default page is not loading up

For about two days now Firefox has been unable to load up images, even in its menus, and the menu buttons do not open up their corresponding windows.
The page that comes up when opening a new tab has the first three webpages displayed, but the second three underneath are blank and the boxes are cut off.
Things like youtube work fine. What could be the problem?

Create a new profile as a test to check if your current profile is causing the problem.
See "Creating a profile":
*https://support.mozilla.org/kb/profile-manager-create-and-remove-firefox-profiles
*http://kb.mozillazine.org/Standard_diagnostic_-_Firefox#Profile_issues
If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over problems.

Hi Andis.
First of all, this is completely normal behavior, although it's a bit irritating, I know. What happens is that when you close Firefox, despite the window disappearing right there and then, Firefox keeps running for a little bit until the whole closing procedure is completed. This can take a fraction of a second on fast computers, or can take a few seconds on slow computers or when Firefox is storing a large session (if you save your tabs). All you have to do is wait a bit until Firefox closes, and then open it again.
To see if it's still running, you can press CTRL+SHIFT+ESC and then, under the Processes tab, you can see if firefox.exe is still there. If it's taking an unusual amount of time to close (which happens very rarely, and only if the browser freezes on exit), you can force the application to terminate from this application (task manager).
Firefox 4.0 will reduce by 97% the time it takes firefox.exe to close, so this problem will be basically erased for Firefox's next version.
Until then, I can recommend you this extension, which helps you restart your browser more easily and without bothering about closing times:
https://addons.mozilla.org/en-US/firefox/addon/3559/
Hopefully this will help.

Firefox is freezing. When I close Firefox, and try to re-start it, it will not open. I need to access Task Manager, where I find Firefox still running. I close Firefox in Task Manager & can re-start Firefox.

Firefox is freezing in the middle of a browsing session. When I close Firefox, and try to re-start it, it will not open. I need to access Task Manager, where I find Firefox to still be running. Once I close Firefox in Task Manager, I can re-start Firefox. This can happen several times in the space of a few hours? I'm running Vista Home premium with Firefox 3.6.16, and this problem has only started in the last 4 weeks. Can Anyone Help? Core 2 Duo E7300 with 4GB RAM.

Sounds like it is hanging when you exit and later try to restart Firefox.

When I close Firefox and open another instance of it to look at a new site I get a pop up window telling me Firefox hasn't shutdown yet.

When I close Firefox and open another instance of it to look at a new site I get a pop up window telling me Firefox hasn't shutdown yet. I am aware of tabs, but I prefer to just open new windows.
Do I really need a pop up window telling me that I just closed Firefox? Is there a way to disable it in options? I can't even use Buzof program to auto click for me. I've never had this issue with any other browser and I find it incredibly annoying.

I am not clear what you mean by:
''the program will only alow 1 website for each time I boot my machine,''
Are you talking about Firefox or something else in the above statement. Firefox will, or should allow you to open quite a few tabs at startup if you wish, although it will be faster the fewer that you do open.
When you say
''I close it the program does not completely close ''
Again what is happening, what error messages if any do you see, and what exactly makes you think Firefox is not closing properly.
Presumably you have already clicked on the blue links in my first post and read those articles.

Hello Brian.
You don't need to restart your computer to open Firefox again: you just need to close it manually through your application manager (CTRL+SHIFT+ESC in Processes tab). Anyway, hopefully this support article is what you need:
http://support.mozilla.com/en-US/kb/Firefox+hangs
What's probably happening is that you may be having a problem with some Firefox add-on that is hindering your Firefox's normal behavior. Have you tried disabling all add-ons (just to check), to see if Firefox goes back to normal?
Whenever you have a problem with Firefox, whatever it is, you should make sure it's not coming from one of your installed add-ons, be it an extension, a theme or a plugin. To do that easily and cleanly, run Firefox in [http://support.mozilla.com/en-US/kb/Safe+Mode safe mode] and select ''Disable all add-ons''. If the problem disappears, you know it's from an add-on. Disable them all in normal mode, and enable them one at a time until you find the source of the problem. See [http://support.mozilla.com/en-US/kb/Troubleshooting+extensions+and+themes this article] for information about troubleshooting extensions and theme. You can troubleshoot plugins the same way.
If you want support for one of your add-ons, you'll need to contact its author.

When I close Firefox and try to restart it, my system thinks it's still running, and I must reboot in order to start Firefox 3.6.11.

When I close Firefox and try to restart it, my system thinks it's still running, and I must reboot in order to start Firefox 3.6.11. I'm running Windows Vista and this is the only program that has this problem. Another symptom is the program does not show up in my recently used programs list nor is it in the task list once I've closed it, though Windows will not open it because it thinks it's still running.

I am also using Windows Vista 64 bit and have the same problem..what i do is instead of rebooting the computer press CTRL ALT and DELETE key. start the task manager and go to the Process tab and look for firefox .exe click on it and hit the end process tab. close that window and firefox should run... and this problem started when i upgraded to firefox 3.6.12
If anyone has a permanent solution please post.

In iPhoto if I select View, then Sort Photos by title, how do I stop it reverting to sorting by date when I close iPhoto and re-open it later?

In iPhoto if I select View, then Sort Photos by title, how do I stop it reverting to sorting by date when I close iPhoto and re-open it later?

In what mode, Events, Photos or in an Album, are you when you select View ➙ Sort ➙ By Title?
As a first fix attempt try the following:
1 - delete the iPhoto preference file, com.apple.iPhoto.plist, that resides in your
User/Home/Library/ Preferences folder.
2 - delete iPhoto's cache file, Cache.db, that is located in your
User/Home/Library/Caches/com.apple.iPhoto folder (Snow Leopard and Earlier).
or with Mt. Lion from the User/Library/Containers/com.apple.iPhoto/
Data/Library/Caches/com.apple.iPhoto folder
3 - launch iPhoto and try again.
NOTE 1: If you're moved your library from its default location in your Home/Pictures folder you will have to point iPhoto to its new location when you next open iPhoto by holding down the Option key when launching iPhoto. You'll also have to reset the iPhoto's various preferences.
NOTE 2: In Lion and Mountain Lion the Library folder is now invisible. To make it permanently visible enter the following in the Terminal application window: chflags nohidden ~/Library and hit the Enter button - 10.7: Un-hide the User Library folder.

I am trying to connect a Macbook Pro to a projector for a Powerpoint presentation. When I use a VGA cable, the color of the projected images are not good. When I use a USB cable, the projected image includes the presenter notes on my computer screen?

I am trying to connect a Macbook Pro to a projector for a Powerpoint presentation. When I use a VGA cable, the color of the projected images are not good. When I use a USB cable, the projected image includes the presenter notes on my computer screen?

To move an iPhoto Library to a new machine:
Link the two Macs together: there are several ways to do this: Wireless Network,Firewire Target Disk Mode, Ethernet, or even just copy the Library to an external HD and then on to the new machine...
But however you do choose to link the two machines...
Simply copy the iPhoto Library from the Pictures Folder on the old Machine to the Pictures Folder on the new Machine.
Then hold down the option (or alt) key key and launch iPhoto. From the resulting menu select 'Choose Library'
and select the Library that you moved. That's it.
This moves photos, events, albums, books, keywords, slideshows and everything else.
Your first option didn't work because you imported one Library to another. Every version and thumbnail is imported like a distinct photo, you lose all your Albums, Keywords etc., the link between Original and Previews is destroyed, the non-destructive editing feature is ruined and so on. In summary: it's mess.
Your second option didn't work because you simply referenced her library on the old machine.

If you don't see Style resource readers on the site, go to that library and set that permission. you could also just load your installation media to a folder, and execute on setup.exe, select repair option. This second option of the installation

When I close Firefox and then try to open it, it says it is already running and I have to close it which I can't do. The only way to open it is to first restart my computer which is a pain. If I can't fix this I will use an other brouser!

I am not sure what more I can tell you. I close firefox. So when I click on the icon it should allow me to open it again but I get a message that says it is already running. Either close it out which I can't do since I already did that or restart the computer.

Try holding control, alt and delete down in succession and then a dialogue box will appear with windows task manager. Once open click on the Processes Tab and look for firefox.exe. Highlight this and then click end process. It should come up with a warning but just click Yes. This should then close firefox and allow you to reopen it from your desktop without shutting down your computer. Hope this helps.

When I close Firefox and re-open it, all previously cached images are NOT loaded from cache. Why?
