Mozilla won't open on my Mac, and when I try to download it says it's in use. Any Help?

Thunderbird was listed as an external drive on my Mac. I accidentally clicked the eject button and now it won't open. I tried to find help in the forum but nothing worked. I tried to re install it and it says it's open and it can't install. When I get a new email the box flashes up on my screen, and if i click it it will open the mailboxes page. I would like to open the mailboxes page by clicking the icon on my toolbar, but I can't seem to make it work. I'm fairly new to Mac, and I'm sure that doesn't help. Anyone have some help?

Start Firefox in <u>[[Safe Mode|Safe Mode]]</u> to check if one of the extensions (Firefox/Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Firefox/Tools > Add-ons > Appearance).

Greetings,
I've never seen this issue, and I handle many iPads, of all versions. WiFi issues are generally local to the WiFi router - they are not all of the same quality, range, immunity to interference, etc. You have distance, building construction, and the biggie - interference.
At home, I use Apple routers, and have no issues with any of my WiFi enabled devices, computers, mobile devices, etc - even the lowly PeeCees. I have locations where I have Juniper Networks, as well as Aruba, and a few Netgears - all of them work as they should.
The cheaper routers, Linksys, D-Link, Seimens home units, and many other no name devices have caused issues of various kinds, and even connectivity.
I have no idea what Starbucks uses, but I always have a good connection, and I go there nearly every morning and get some work done, as well as play.
You could try changing channels, 2.4 to 5 Gigs, changing locations of the router. I have had to do all of these at one time or another over the many years that I have been a Network Engineer.
Good Luck - Cheers,
M.

HT1947 Remote app requirements are stated as "software version 3.1.3 or later". I am running 4.2.1 and when I try to download it says 4.3 required. Where can I get the (old) version that runs on my IOS?

'Remote' app requirements are stated as "software version 3.1.3 or later". I am running 4.2.1 and when I try to download it says 4.3 required.
OK, I understand that new versions make use of facilities that come with new versions of IOS, but there is/was a version that runs on 3.1.3 and therefore, I assume 4.2.1. Where can I get the (old) version that runs on my IOS?
The app store seems to ignore all legacy equipment owners, and want me to spend loadsa money to get the latest shiny toy. It probably makes business sense, but I dislike companies that take that approach. This is my first venture into smart phones, and I like the IOS interface, but I'm not sure I can afford the maintenance.

This is standard for Apple. While there is little official mention of the software support lifespan for equipment, typical support has been about 4-5 years for computers. It strikes me that newer items, especially mobile devices, are not built as sturdily nor do they have the hardware upgrade capabilities required to keep up with newer systems. When we bought an iPhone 4S we were told by the person in the store we'd probably be looking at a newer model in two years. The iPhone 3G could be anywhere from 2 to 4 years old, putting it well into.
As for app availability, Apple typically pulls old software versions from its site when new versions appear. If it is a non-Apple app then I guess it is up to the vendor. It is indeed tiresome but it is not at all unusual. Since I only ever run used Macs, I download current versions even though my computer won't run them, stick them on a hard drive, then I have them when I upgrade to a newer used computer. If you run older equipment you have to learn a different mode of operation to exist with the Apple 'new and innovative' but 'forget about the old' philosophy.

I bought an app and when I try to download it says I have already purchased and It will be downloaded with no charge

I bought a app on the App Store and when I try to download it says "you have already purchased this all, it will download now with no additional charge"

I had same problem. All that was next to app was the cloud icon (ie.not 'open') and kept getting same message when trying to download. I found this fix on another discussion that worked wonderfully for me. The guy who found this deserves credit:
1) Open iTunes and go to the iTunes Store
2) Click on your account ID in the upper left-hand side of the window and select account from the drop-down
3) You may have to enter your password, but will then be shown the Account Information screen
4) Look at the top of this screen for a section indicating you have a pending download and click download
5) Either install via sync or on your device itself
I just re-clicked on the cloud in the app-store on the device and it finally worked! It must have been in some sort of app-limbo.

Are you sure you have the newest version of iTunes 11 and newest version of iOS6? Go to Software Update and make sure you do.

I have snow leopard on mac and when I try to download Firefox i get 'not recognised' in the download. Help? Pleas?

Hello,
I have tried to download Firefox onto my Macbook - with snow leopard running system. When I try to open Firefox the message is 'not recognised'. I really want Firefox - please can you help?
Thank you.

It's referring to another application that is running on your PC. Temporarily disable any A/V software you have running on the system and try to restore it again. Make sure you don't have any other software/programs on your PC that could be scanning or interfering with the restore process.
B-rock

Firefox won't open anymore on my computer. when i try to download again, it tells me to close firefox first.

When I click on the firefox icon, it just does nothing.
So I tried (through another browser- Chrome) to download another version of firefox. It said it's open and I have to close it.

I never expected Mozilla to neglect the users of Apple's PowerPC (PPC) computers, while still supporting much older operating environments such as Windows XP. So, I should just throw away a $6,000 system, which is still fast and functional, and contribute masses of heavy metals to land-fills because…?
I'm hurt and confused after supporting Firefox for many years — installing and using it not only on my own computers but on most of my customers' computers. Now I have to tell my customers with PPC Macs they can't have a secure cross-platform browsing experience from Mozilla. They'll have to learn to use some other browser, or buy a new computer.
If one doesn't buy a new computer every year, one doesn't deserve Firefox 4. This is sort of sounding more like a Microsoft™© doctrine. (But wait, I can still have Firefox 4 on a ''SERIOUSLY CRAPPY WINDBLOWS XP pile of rubbish?!'') Please open your eyes Mozilla. This just doesn't make sense.

I have a MAC and when I try to use Adobe Reader, I get a pop up telling me I need to accept the end user agreement. It instructs me to go the Abobe Reader Installer download , double click and accept the agreement, but there is no agreement. What should

I have a MAC and when I try to use Adobe Reader, I get a pop up telling me to lauch ADobe Reader and accept the end user license agreement, but when I do that, there is no agreement to acknowledge. What should I do?

I have the same problem as Pam101. I am on OS X 10.9 and Safari 7 (actually on 2 iMacs). The one iMac is fine but the other with the same versions and settings Adobe Reader will not work. What happens is the Adobe Reader icon appears on the dock, bounces once and that's it. When trying to open a .pdf file from a website a new tab is opened on Safari, the background is black and there is a pop up message (black test on a white background) that reads: "Adobe PDF Before proceeding you must first launch Adobe Acrobat and accept the End User License Agreement." This is all very well but if Adobe Reader will not launch how on earth is it possible to accept the End User License Agreement terms? Very, very annoying, especially since it all works just fine if I launch a .pdf file from a website using Chrome. What is going on here and who do I talk to in order to fix this problem - Apple or Adobe?

I had the geek squad from bestbuy supposedly install iphoto 11 on my mac but it is not there and when i try to download it it say the app has been download by another user on this machine. What do i need to do get get this app on my system? If they could not do it right the first time I do not have much faith in their advice.

Assuming you've done a system wide search for it including the Applications folder and it's not there......
I think you will need to address this with them - did you pay them for the application? Or was your purchase price to include it? And the question(s) to ask them:
If the app store states that it has been downloaded, ask them where it is and which Apple ID they used. (the store keeps track of Apple IDs and machine IDs on everything you download).
I have absolutely no faith in their advice; however, in this case, it's not so much technical advice, but an answer to your questions: you paid for something and it appears not to be there.

Probably wasn't a good idea to install beta software on a device when you're not a developer.
Apple clearly states that beta software is not to be installed on production devices.
Not really much you can do except wait for iOS 6.1 to be officially released and then install it.

It sounds as if you downloaded Adobe Acrobat Pro. If you did, uninstall it. Then repair Adobe Reader.
The free Acrobat account has no connection to any of this.

I purchased a macbook air from someone on craigslist, and when i try to download iPhoto, it tells me that these apps were already designated to another apple id.

I purchased a macbook air from someone on craigslist, and when i try to download iPhoto, it tells me that these apps were already designated to another apple id. any way to reset the app store from thinking it's still alligned with him? Lion was reset already, but this isn't. If i download on my mac mini, will i then be able to retrieve the download on my air?

Hi...
On the MBAir drag the iPhoto app to the Trash, empty the Trash.
Then try purchasing and downloading iPhoto.
You can re download iPhoto on all your authorized Macs. To authorize the MBAir, launch iTunes. From the menu bar click Store > Authorize This Mac. You will be prompted for your Apple ID and password.
Open the App Store. From the menu bar click Store > Sign In
Click Purchases from the top of the App Store window.
Select which apps you want to re download. Then right or control click where you see Installed then click Install.
Make sure and use the same Apple ID used for the original purchase.
