Why does my latest version of Firefox under Windows 8.1 always report problems with security certifactes - even on mozilla,com - when my latets version on Ubunt
On my desktop, I have been using Firefox V27 on Ubuntu 12.04 for some time. It uses secure sites - such as https://mozilla.org - and accepts the Security Certificates quite happily, so I am not even aware there is any issue.
My new laptop is Windows 8,1, and I have installed Firefox- the latest version.
Whenever Firefox visits a secure site, it ALWAYS says that there is a problem with the security certificate - even at mozilla.org - and warns me away. I have to complete a security exemption.
Why is this, and how can I fix it?
Thanks in anticipation.
unfortunately the fiddler2 issuer in certificates might be a sign of unwanted software present on your pc that is intercepting secure network traffic. please go into the system control panel and uninstall programs like BrowserSafeguard, BrowserSafe, SafeGuard or other software that sounds suspicious and didn't get installed by you intentionally.
<br><sub>reference: https://support.mozilla.org/en-US/questions/982532#answer-520145</sub>
afterwards, run a full scan of your system with different security tools like the [http://www.malwarebytes.org/products/malwarebytes_free free version of malwarebytes] & [http://www.bleepingcomputer.com/download/adwcleaner/ adwcleaner].

Why does the latest upgrade to firefox run and run on my MAC without ever loading
I get a message saying update Firefox now. I hit the enter and the Firefox update runs, last time I tried I went to another page to keep working and the update was running for over 30 minutes. The about Firefox page shows issue 33
Hello Norrsken, please try to download and install firefox. Do the next steps:
1. Download a copy of the latest firefox from http://www.mozilla.org/en-US/firefox/all.html (full installer)
2. '''Trash''' the current Firefox application to do a clean install.
3. Install the version that you have downloaded.
Do not select to remove your personal data, your profile data is stored elsewhere in the [http://kb.mozillazine.org/Profile_folder_-_Firefox#Mac Firefox Profile Folder], so you won't lose your bookmarks or other personal data.

scrolling overflow on tbody is no longer supported because that is not allowed in CSS 2.1 specification.

I cannot install the latest version of Itunes under Windows XP because itunes.msi cannot be found in order to remove the older version (11.0.1.12) of itunes. Is there any other way I can accomplish an upgrade without using the Itunes.msi file?
(1) Download the Windows Installer CleanUp utility installer file (msicuu2.exe) from the following Major Geeks page (use one of the links under the "DOWNLOAD LOCATIONS" thingy on the Major Geeks page):
http://majorgeeks.com/download.php?det=4459
(2) Doubleclick the msicuu2.exe file and follow the prompts to install the Windows Installer CleanUp utility. (If you're on a Windows Vista or Windows 7 system and you get a Code 800A0046 error message when doubleclicking the msicuu2.exe file, try instead right-clicking on the msicuu2.exe file and selecting "Run as administrator".)
(3) In your Start menu click All Programs and then click Windows Install Clean Up. The Windows Installer CleanUp utility window appears, listing software that is currently installed on your computer.
(4) In the list of programs that appears in CleanUp, select any iTunes entries and click "Remove", as per the following screenshot:
(5) Quit out of CleanUp, restart the PC and try another iTunes install. Does it go through properly this time? -

WHY DOES MY MAC BOOK PRO SHUT OFF ON ME? SO FAR THE INFO I GOT 4 IT IS A MAC OS X VERSION 10.7.3 THE PROCESSOR IS 2.4 GHZ INTEL CORE 2 DUO MEMORY IS 2 GB 667MHZ DDR2 SDRAM I DON'T KNOW HOW OLD IT IS BECAUSE I BOUGHT IT USED SORRY I HOPE THIS HELPS THANK YOU
Sounds to me like you may have gotten a machine with hardware issues, but it's hard to say. It will shut down if it gets too hot, but that's not a normal occurrence. I have never seen a MacBook Pro shut down due to heat, even after lengthy 3D gaming sessions where the fans are running fast and the bottom of the machine is unpleasant to touch.
First thing I would try to do is reset the SMC. If that doesn't help, erase the hard drive and reinstall the system from scratch, which you should always do with a used machine anyway.
If a fresh system doesn't help, you'll need to get it checked out by Apple.
Edit: Oh, and sig is absolutely right... please don't post in all caps! It's very irritating. -

Why does it say in the Firefox Safe Mode article that all of the changes are temporary while in Safe Mode, then later it says "Note: The following changes cannot be undone."?
When you open Firefox in Safe Mode, it automatically disables your custom settings, themes, and add-ons. THOSE changes are temporary.
However, if you click any of the boxes underneath the line, "You can make some or all of these changes permanent", and then choose "Make Changes and Restart", everything you checked will be forever changed, even when you start Firefox again in 'normal' mode. [See attached image for a preview of the Safe Mode options].
To be clear:
1. If you check any of the boxes but do NOT select "Make changes and restart", those things will not be changed at all in safe mode.
2. If you select any of the boxes and you DO select "Make changes and restart", you will permanently lose any of the items you checked (bookmarks (except for backups), user preferences, etc.).
If you performed the action in step 2 above, you will only be able to restore those things if you have a previously created back-up of your Mozilla Profiles folder (not the same as the Firefox program folder).
Hope this helps. -
Why does it say waiting for activation under facetime switch
why cant i access facetime and why does it say waiting for activation under the facetime switch?
Hi,
If you have a Jabber ID used in iChat and you add a Buddy the Buddy gets an Authorisation Request invite.
iChat sends this Invite once.
The Buddy cannot be properly in your Buddy List until they accept.
However other Jabber Apps constantly sends the Authorisation Requests again and again until the person Accepts or Declines.
In iChat if the Buddy misses the Request the Buddy list is left hanging with the "Awaiting" message.
GoogleTalk and Facebook IDs ware valid Jabber names if you have Enable "Talk" on Google an "Chat" on Facebook.
Try Deleting the Buddy from the list (Highlight and then Backspace key)
Then Add them when you know they will see the request.
(Or get a Third Party Jabber app and run that after adding their name until they reply)

Why does Apple kick their old subscribers under the bus? I have an iMac G5 1.9 and 2.1 computer using Leopard 10.5.8 system, and I cannot renew my MobileMe account, why? Is Apple incapable of keeping their old subscriber accounts active and still update their system? Maybe I should look into buying a PC in the future? I eagerly await your reply. Thanks
MobileMe is being terminated in two weeks. If you have files on your iDisk which are not also on your computer you need to be downloading them as soon as possible or you will lose them.
You can migrate to iCloud and set Mail up manually to receive your @me.com mail:

You will not be able to sync calendars or contacts. If you want to have general online file storage you will need to find a third-party alternative - this page examines some options:

Guys, my browser is going crazy and every website that I am on changes in about 10 seconds to 2 minutes to another webpage. I even downloaded a newer 5.0 version of firefox and I am having the same problem.
Your System Details are showing Fun Web Products. Suggest you look in Add-ons - Extensions and Plug-ins, and Control Panel>Add/Remove programs or >(newer version) Programs and Features. You could also do a search of your computer.
Fun Web Products(associated with MyWebSearch) always seems to cause problems, Alexa does, too, but less often - there may be conflicts.
I'm not an expert on these two products. I'm afraid I can only alert you to the problems. Google will show you plenty of evidence of problems. You might also try the Search Firefox Help box above - a gold mine but it usually requires a lot of digging.
You can start Firefox in Safe Mode - Hold Shift Key down as you double click on the Firefox icon>ignore the page that opens>Continue. If that improves things you could do a little troubleshooting(Safe Mode, Problematic extensions etc), use default theme, -

You can try to disable hardware acceleration in Firefox.

My tesm develops .net applications that must support many browsers and we need access to download older versions of FireFox for windows and mac computers, so that we can test our application prior to rolling out a new version.
Where can I download older versions of FireFoxFirefox 3.5 is an antique version that is chock-full of security vulnerabilities.<br>
Firefox 3.6 also contains security vulnerabilities; it stopped being supported on April 24.
* [https://www.mozilla.org/security/known-vulnerabilities/ www.mozilla.org/security/known-vulnerabilities/]
If you can't run the latest version because your system doesn't meet the requirements, it's highly recommended that you use another browser that is secure. TenFourFox is a third-party build of Firefox that is kept up-to-date and runs on Mac OS X 10.4 and PowerPC Macs (as a side note, I've never seen the site go down; whatever problems James noticed 9 months ago must've been a fluke).

If your system can run the latest version, but you want to downgrade because you've experienced problems, please start a new thread and someone will try to help you.
If you understand the security risks but want to downgrade anyway,

Why does my ipad2 no longer receive photos on iMessage? Iphone works perfectly with iMessage photos. Ipad2 used to work fine. Is it an ios8 issue? Help!
Hello,
Where may I be able to contact and speak with a prepaid representative? Strictly through phone calls? (I am at work 12 hours a day)
And I apologize for posting in the wrong area - I saw Apple support so I went here.
I'm almost certain my phone is the problem. I have gone through resetting the network settings a dozen times on my phone, even did it on my dad's. Now my texts are beginning to do the same when I text my fiance.
Resetting the network settings DOES work -- the problem is it will work for a day or two or for only a few hours - then I'll have to do it all over again.
