I have just upgraded to firefox 4, but it does not load up when i press icon

originally, i upgraded directly frm firefox site and it launched. then after shutting down, it has not loaded up since. i have deleted the old firefox off my laptop and attempted to re-install, but no luck. it still does not load up.
i have windows 7, and see the spinning wheel (like it is doing something), but nothing happens.

Just for starters see if you can get Firefox going. Instead of double Left clicking, Right click on Firefox icon>Open.
If that doesn't work, try opening via Firefox in the Start Menu or Programs List. If that works try creating a new desktop icon.
Then you try to start Firefox in Safe Mode - Hold down the Shift Key as you double click on the Icon> don't check any of the boxes on the page that appears>Continue. You have now disabled all extensions and also Hardware Acceleration.
Make sure your plug-ins such as Flash are up-to-date.

You should look up "Problematic Extensions"
http://kb.mozillazine.org/Problematic_extensions ,
and try disabling third party toolbars.
If Firefox works in Safe Mode you have a culprit or conflict. If you are able to, you disable and re-enable extensions progressively until you find the problem. you will need to work your way through this -

Cannot download videos
This is caused by the RealPlayer Browser Record Plugin extension. To fix it, disable the extension.
The RealPlayer plugin will still work.
At the top of the Firefox window, click on the Firefox button (Tools menu in Windows XP), and then click Add-ons. The Add-ons Manager tab will open.
In the Add-ons Manager tab, select the Extensions panel.
Select RealPlayer Browser Record Plugin.
Click on Disable.
Click Restart Now to start Firefox with the extension disabled. My add-on manager says the add-on is disabled.
I tried this and it didn't work, what else?

I have just purchased OS X Lion but it does not download although it appears in my purchases. Any tips to get the download active? GJ

I have just purchased OS X lion via App store. this shows as a purchase but it does not download after hitting download button in recent purchases in App store

Hello Gregory,
If you have properly upgraded Snow Leopard to 10.6.8, say with the combo updater v1.1, Lion should run comfortably with 4GB of RAM on your model.
You may be able to inject a further 2GB of Ram and to check that, go to Crucial.com and feed in your Machine specs. The site has a tool which will confirm the maximum amount of RAM you can fit.
It's not too difficult to fit by yourself and Crucial give instructions how to do it.

Go to your actual realplayer (program), click the top right button (Realplayer with an downwards arrow) and update your software. Make sure Firefox is closed while you do this.

what shall i do now?

I have just bought a new Imac and it will not load my copy of FCE 3.5 as it says "PowerPC applications are no longer supported". So how do I get to use the version of FCE I am used to and have paid for ?

I do not have any experience with Final Cut, but if you have existing projects that you MUST access; then you are in need of a solution on your new iMac in Mountain Lion!
Unfortunately you got caught up in the minor miracle of Rosetta. Originally licensed by Apple when it migrated from the PowerPC CPU platform that it had used from the mid-1990's until the Intel CPU platform in 2006, Rosetta allowed Mac users to continue to use their library of PPC software transparently in emulation.
However, Apple's license to continue to use this technology expired with new releases of OS X commencing with Lion (and now Mountain Lion). While educational efforts have been made over the last 6 years, the fact is that Rosetta was SO successful that many users were caught unaware UNTIL they upgraded to Lion or Mountain Lion.
Workarounds:
1. Purchase a used Mac that will run Snow Leopard (with the optional Rosetta installed) and continue to run FCE on that Mac (you can actually use Screen Sharing with a "headless" used Snow Leopard Mac Mini and use the 27" screen from your iMac to view and work FCE in the Mac Mini environment);
2. Upgrade to an Intel compatible version of FCE and hope it converts your existing projects to its newer format correctly. There is much debate that the newer version of Final Cut are eliminating many needed features; for example Final Cut Pro X vs. Final Cut Pro 6 -- many users are staying with version 6;
3. Install Snow Leopard (with Rosetta) into Parallels and then install FCE in the Snow Leopard environment:

Full Snow Leopard installation instructions here:
http://forums.macrumors.com/showthread.php?t=1365439
NOTE: STEP ONE of the instructions must currently be completed on a Snow Leopard or Lion Mac and the resulting modified Snow Leopard.cdr install file can then be moved over to your Mountain Lion Mac for completion of the remaining steps.
NOTE 2: Computer games with complex, 3D or fast motion graphics make not work well or at all in virtualization.

Firefox 3.6.13 does not load AOL mail - it logs in ok but does not load

I updated Firefox to the latest version and it will not load my AOL eMails.
I can however log into my AOL account and it shows the Welcome message and number of unread mail and also shows the folders etc. including Spam folder but it does not load the eMail or will not allow me to open any eMails.- Just shows blank.
BTW I can access my AOL mail Box with Internet Explorer.

Comcast just replaced my cable modem/wireless router. All devices connect properly except my iPhone 4. It shows itself to be connected to the network, but it does not load any web page. Resetting the iPhone does not solve the problem. Any suggestions?

Thank you for your response.
I had rebooted the router (several times, actually), to no avail.
I do not know the answer to whether MAC filtering is enabled on the router. Have tried to find info about that, but unsuccessfully. Router is an Arris TG852G, supplied by Comcast. I would be surprised if MAC filtering were the issue, since in addition to the computer, we have successfully connected several other devices to the wifi, namely an iPad, a Android phone and a Kindle Fire - all able to access internet pages through the wifi, and all without a need to add the device to a MAC address whitelist. To add to the mystery, the Comcast tech was able to connect his iPhone 4 to my network and access web pages. He was unable to connect my iPhone, however, after trying for some time.
I seem to recall reading somewhere that an iPhone cannot connect to a wireless "n" router, only "b" or "g". The Arris router is described as a n/g/b compliant router, and as noted the Comcast tech was able to connect his iPhone, so don't know why that would be the issue here.
By the way, my iPhone does connect wirelessly to my network at home. This difficulty is at a second home.
Any other thoughts would be appreciated.

Hi Marcel1no,
Welcome to the Apple Support Communities!
I understand that it can be frustrating when an application downloaded from the App Store is not behaving as you would expect. In this situation, I would recommend using the attached article for information on troubleshooting apps downloaded from the App Store.
