I downloaded and installed Firefox but I can't open the program.

This is the third time I've downloaded Firefox on this computer and have been unable to open it. I allowed it to become my default browser during installation but clicking on any weblink yielded this error message: "There was a problem sending the command to the program." When I changed the default browser back to Internet Explorer I could open websites using it, and also using Google Chrome, but still can't open Firefox.

HT201077 I have downloaded and installed iCloud, but I can not open it.

After downloading and installing, signing in and getting the icon on my dock, why can I not OPEN it?

It isn't clear what you have done. You can't download iCloud, there isn't a download, it comes as part of the operating system. Also there is no Dock icon for iCloud.

Try resetting Photoshop Preferences. Use your Photoshop start icon to launch Photoshop and immediately press and hole Shift+Ctrl|CMD+Alt|Option keys Photoshop should Prompt you with Do you want your Preferences deleted. Reply yes. Photoshop should then delete your user ID preferences and then create a default set of preferences for your ID and start successfully.

I have transferres Adobe programs from my old Mac Book to my new Mac Book Pro, but I can´t open the programs!?

I have transferres Adobe programs from my old Mac Book to my new Mac Book Pro, but I can´t open the programs!?

Adobe programs don't do well with migration. You should uninstall them, run the cleaner tool (CS Cleaner Tool for installation problems | CCM, CS6, CS5.5, CS5, CS4, CS3), and reinstall from the original installers, but you also need to be aware that many older programs are not supported on newer versions of OSX so this may not go smoothly.

Have installed adobe flash player and is in downloads, and my documents, but I can't open it due to conflicting instance. No idea what to do next

Trying to open adobe flash player so my daughter can play educational games. Think it's downloaded ok, but it won't open due to 'conflicting instances'. I don't even know what that means!

This is the full procedure for installing Adobe Flash for Firefox.
1.Download the Flash setup file from here: 
[http://fpdownload.adobe.com/get/flashplayer/current/install_flash_player.exe Adobe Flash - Plugin version]. 
Save it to your Desktop. 
2. Close Firefox using File > Exit 
then check the Task Manager > Processes tab to make sure '''firefox.exe''' is closed, 
{XP: Ctrl+Alt+Del, Vista: Shift+Ctrl+ESC = Processes tab}
3. Then run the Flash setup file from your Desktop.
* On Vista and Windows 7 you may need to run the plugin installer as Administrator by starting the installer via the right-click context menu if you do not get an UAC prompt to ask for permission to continue (i.e nothing seems to happen).

I just installed 10.2.2. When I tried to start iTunes, I got the message that Rosetta needed to be installed to open iTunes. It downloaded and installed Rosetta but iTunes will not open and it no longer has the iTunes icon. What do I do now?

I installed iTunes 10.2.2. When I tried to open it, I got the message that iTunes needs to install Rosetta to open. It then appeared to download and and install Rosetta. When I try to open iTunes, the icon bounces but iTunes does not open. The icon has also changed from the usual iTunes icon. What do I do now?

I have a 2010 MBP15 which I do not use as much as my pc. When I do, I check for updates and I believe I updated iTunes to 10.2.2 a week or so ago. Since I still use iTunes primarily on my pc, I didn't bother firing up the updated iTunes on the mac.
Last week, when I actually started iTunes on the mac, I got the message that Rosetta needed to be installed. Like abefighter I stalled. I surfed the net, read this thread to get some hints as to w** was going on.
When I checked the system profile in the mac, I think it showed PowerPC for 'kind.' Surfing the Internet I found out Rosetta was something needed to help applications work on PowerPCs. But wait, since this MBP is an Intel, why would or should it be asking me for some stone-age plug-in that was never mentioned in all the previous updates for iTunes until now? Fyi, the iTunes icon on the dock had changed to what I think is an AppleWorks icon.
So, I assumed that the update that resulted in my mac was corrupted. At first I scoured for 10.2.1, thinking that the last version was a dud, but in vain, nowhere to be found. I gave up and settled for a fresh 10.2.2. I did a casual delete, without touching any of the related personal preference files in my folder and it now which works fine. I'm glad I didn't jump to install Rosetta; I read elsewhere about someone who actually went through with the Rosetta install that resulted unhappily.
Unless the mac in question is a PowerPC, I would doubt the need for Rosetta installation.

I downloaded and installed Lion now i can't find the file to burn

Does anyone know where the file is after you install the lion update. I want to burn it to disk but can't find it anywhere

why ? it is a fact.
The "install Mac OS X lion.app" is only a virtual folder, inside this folder ( right-click and "show package contents" ) you will find the real installation files and a hidden file, which contains the base system dmg ).
The net is full of instructions on how cou can create a bootable drive with the files inside the app.
After Lion has been installed from within Snow Leopartd it is too late, that's not rude to say that you should have taken care of that before..
At least what you are now experience is how Apple has invented the install process : One time launch within Snow.
some time later ( next month or so ) Apple will sell bootable USB drives with Lion for all those that have no Internet. Your second chance, then.

I cannot start my old Dell PC, so I set up an old backup PC and installed Firefox. How can I import the bookmarks on the disabled computer to my new computer?

My old computer was a Dell Dimension desktop running Win XP Pro. The current one is a ProTec (from MicroCenter retail store) running Win XP Home.

I don't see any web site when I connect to firefox but I can't uninstall the program because it says that I must close firefox first. I can't do that because it did not show the page.

I just upgraded to firefox 6 and it did not include the add ons. It said that the add ons were out of date. When I try to open yahoo.com I don't have any site to see. I can open chrome browser and IE without any problem. Before this new problem I was having a problem with firefox taking a long time to open. I have no problem with the other browsers.

In case you haven't solved this by now...
Sometimes your security software will block new programs from accessing the internet. Are you getting any alerts along those lines?
Sometimes Firefox will stall during startup and never display its window. In that case, you may need to manually "kill" the firefox.exe process using the Windows Task Manager before trying to start Firefox again.
You can display the Task Manager by pressing Ctrl+Alt+Esc. Windows 8.1 has a different display than Windows 7, so I have to go by memory. If you see a tab named Applications, check that one first. Then check Processes, and finally check Details. If you find Firefox or firefox.exe on any of those tabs, select it and End Process (or other action to shut it down).
After you are done with the Task Manager, try starting Firefox up again.
