Since installing Firefox, every move my mouse or cursor makes causes the screen or parts of it to balck out. You just cannot work with it like this. What might the problem be??

As soon as I launch Firefox, parts or all of the screen will go black as if wholly highlighted in black. You cannot see anything or do anything until the screen or the blackening disappears! Typing this report is taking long minutes because I have to wait for blackness to clear between keystrokes!
what might be the cause? And what can I do about it? The older versions of Firefox did not do this. It began when I installed the present version (7.0.1). Though I have uninstalled and reinstalled several times, the problem persists!

You may have '''Switched ON Caret Browsing'''. press '''F7 (on Mac: fn + F7)''' to toggle '''Caret Browsing ON/OFF'''
* click '''Firefox''' button and click '''Options''' -> Advanced -> General -> remove
Checkmark from '''Always use the cursor keys to navigate within pages'''

Since installing Firefox 4, screen goes black when dormant and will not automatically reopen on first try.

Since installing Firefox 4, if I leave the computer (desktop with a Viewsonic VG1930wm monitor), the monitor will go to blackscreen...not the starfield screensaver. If I move the mouse, the screen will only momentarily go back to the last desktop...and then almost immediately black screen again. I typically have to turn the monitor on and off five or six times...and move the mouse each time, before it will stay open to the desktop. Any ideas?

Standard troubleshooting steps in order are as follows:
Power the iPad off and on.
An iPad reset, which is done by pressing and holding the home button and the sleep/wake or on/off button simultaneously until you see the Apple logo and then release.
Restore your iPad with iTunes from your iPad's backup.
Restore your iPad with iTunes as a new iPad or not from your iPad's backup.
If no change after the last step, your iPad has a hardware problem.

Since installing Firefox 29, my router constantly reboots on its own

Since installing Firefox 29, my router constantly reboots on its own. Is anyone else having this problem? And could it indeed be caused by Firefox?

Do you have any security software that may undo changes and restore a previous setup?

Since installing Firefox Sync my master password is requested randomly.

Since installing Firefox Sync my master password is requested randomly. is there a way of stopping this happening.

Somewhere around Firefox 29, Firefox changed how Sync accounts work. Please see this article for more information: [[How to update to the new Firefox Sync]]. If you can't do that in Firefox 33, you may want to install Firefox 29 temporarily to do the account change, and then update to Firefox 33. This article has information on how to find clean old versions of Firefox: [[Install an older version of Firefox]].

Since installing firefox update I no longer have a padlock displayed when on secure sites. Is this still OK?

Since installing Firefox update today, 11/11/2011, when entering secure web sites I no longer have the display of a padlock. I still have Https. I am wondering if the security of these sties is still OK.

The Statusbar is gone and the "lock" with it as of Firefox 4.0. Security information about a web page is shown by the Site Identity Button. 
The old padlock could give users a false sense that a site is secure by not supplying all of the information about a site and only showed that there is a secure connection that didn't guarantee that you are connected to the right server. The Site Identity Button was introduced in Firefox 3.0 to show more complete "identity" information for HTTPS web pages.

You can add a padlock to the location bar with the Padlock add-on- https://addons.mozilla.org/firefox/addon/padlock-icon

A possible cause is security software (firewall) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.

How do i make firefox automatically open a file. "Do this automatically with files like this from now on." does NOT work.

I have firefox set to Open .wav files with VLC and i have the check box marked to "Do this automatically for files like this from now on." But every time i click download for a .wav voicemail from gmail, i get the same dialog box. I just want firefox to hand the downloaded file to VLC and play it. I don't want to have to click anything after i click the download link. Isn't that action what i'm telling firefox to do after i mark the checkbox with "Do this automatically with file like this from now on." ? Isn't that implied with my selection of the box? How can i fix this?i want to click a "download" link for a .wav voice mail in Gmail and have it automatically play in VLC without any further interaction from me.

No it's saving the preferences and the check box remains checked from session to session. It will even continue to ask me to what to do with the file even in the same session when i try to download the same file again 5 seconds after i downloaded it the first time.

1. Restart your computer to stop any Adobe process that is running.
2. Click on the following Adobe link. Go to the bottom where it says "Still having problems?". Click on the version of Flash Player for your browser.

Remove the files in the updates and updates\0 folder.
You may need to delete active-update.xml and updates.xml as well if present.
XP:
C:\Documents and Settings\<user>\Local Settings\Application Data\Mozilla\Firefox\Mozilla Firefox\updates
(%USERPROFILE%\Local Settings\Application Data\Mozilla\Firefox\Mozilla Firefox)
If you have problems with updating then easiest is to download the full version and uninstall the currently installed version.
You may need to remove the Firefox program folder to do a clean install of the new version.
Do a clean (re-)install:
* Download a fresh Firefox copy and save the file to the desktop.
* Firefox 4.0.x: http://www.mozilla.com/en-US/firefox/all.html
* Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
* Do not remove personal data if you uninstall the current version.
* It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
Your bookmarks and other profile data are stored elsewhere in the [http://kb.mozillazine.org/Profile_folder_-_Firefox Firefox Profile Folder] and won't be affected by a reinstall, but make sure that you do not select to remove personal data if you uninstall Firefox.

I bought the Keynote app for my MacBook, but when I open the application and try to install it, I get an error message saying that the application will not work with my MacBook. What gives? And, can I please request a refund? ($19.99 = a week's groceries)

I bought the Keynote app for my MacBook, but when I open the application and try to install it, I get an error message saying that the application will not work with my MacBook. What gives? And, can I please request a refund? ($19.99 = a week's groceries).
Thank you for your help! - I did try looking for all available specs about Keynote on the Apple iTunes website, and found nothing that could help me. HELP!

1
Close all iWork applications
2
Uninstall Keynote; this must be done with an application remover tool to delete the installation properly. Appcleaner is known to work correctly for this purpose, it is free and can be downloaded from here: Appcleaner Download
3
empty the trash
4
shutdown the Mac and restart. After the start up chime, hold down the shift key until the apple logo appears
let the Mac complete the start up procedure completely, it will take longer than usual as the hard drive is being repaired
5
Reinstall Keynote by logging into the Mac App Store using download / install

I need to install Internet Explorer 6 or greater on my iMac to work with a program. How is the best way to do that?

I need to install Internet Explorer 6 or greater on my iMac (intel processor) running MacOS 10.6.8 to work with a program. How is the best way to accomplish this?

There is no way. IE has not been available for the Mac for years now.
Your only option is to install native Windows and use that - either through a bootcamp dual-boot scenario, or use a virtual machine to run windows in (eg. Parallels or VMWare Fusion). Either way, you will need a full retail install disk for Windows.
P.S. the last version of IE for Mac was for PPC machines, and it was discontinued in 2003.
