Firefox (latest versions) on both Mac 10.6 and Windows 7 show "this Connection is Untrusted" on my bank site

This started for me 1/17/2011 on the savingsbank.com website:
Firefox (latest versions) on both Mac 10.6 and Windows 7 show "this Connection is Untrusted" on my bank site https://www.savingsbank.com
NO other browsers - Explorer, Chrome, Safari - give this error box on this site. Please advise if this has to do with the bank site? or Firefox compatibility.
Saw in a forum someone else having this problem and they were told it had to do with their Date and time being off?? I've been on several computers, all with the correct date and time and they've all shown this Insecure Certificate statement on my bank site with Firefox and no other browser.

I've looked at the banking site with IE8 and it does NOT show me that "This connection is Untrusted" window. (please see attached screen shot of viewing the site with IE8) It opens fine and has "Identified by Network Solutions" showing on the address bar as it always does.
The latest version of Opera (not earlier ones) does show a problem with the website's security certificate.
We've contacted the bank about this, and they say there's no problem with their certificate but are looking into it.
My question remains, why only Firefox and one version of Opera claim this and NO other browser?

HT1338 Software Update is not finding latest release (April 3) of Java 2012 001 Update for Mac OS X Lion 10.7.3 on iMac mid-2007 that downloaded automatically on iMac mid-2011

Software Update is not finding latest release (April 3) of Java 2012 001 Update on my iMac mid-2007, but it downloaded it automatically on my iMac mid-2011 yesterday. Both are running Mac OS X Lion 10.7.3. When I try to download the update manually from Apple on my older iMac, it downloads okay, but when I try to open the dmg file, I get a warning message saying that opening this update may make your computer LESS secure. Do you want to proceed? (I did not).
Why would Software Update find this update and install it automatically on one iMac and not the other, if they are both running the same version of Mac OS X Lion? I checked the installed software list on my old iMac and the Java update does not appear there. Why would this update make my old iMac less secure?

Recall that Java is not installed as part of Lion.
You have to install it (and are asked if you want to) when you first try to run some java stuff.
Is it possible that the iMac 2007 does not have Java yet?
Try this: open Terminal (from Utilities) and type java -version (exactly like that, with the space before the hyphen).
What do you get?
Consistent with this theory is that the dmg thing gave you the warning - installing java might make your machine less secure because java is a means for bad guys to try to do bad things to your computer.

Running latest version of Firefox on latest release of Ubuntu. When launched Firefox freezes. Am using wifi. Wifi works because it downloads updates fine.

I have a new build of Ubuntu latest release 11.10. When I launch Firefox it seems to freeze. Ubuntu still works it's just Firefox that is not reponding. It just stays in the mode of trying to load the homepage. None of the toolbar options are accessible at this point. I am connecting to router using wifi. The wifi works since I am able to download Ubuntu updates.

Your UserAgent string in Firefox is messed up by another program that you installed.
[http://en.wikipedia.org/wiki/User_Agent]
type '''about:config''' in the URL bar and hit Enter 
''If you see the warning, you can confirm that you want to access that page.'' 
Filter = '''general.useragent.extra.firefox''' 
Right-click that preference and select '''Reset''' 
Then restart Firefox

Latest version of Firefox is not compatible with my Mac G4 dual processor?

Have used Firefox for a long time now and suddenly the new
updated version does not work with my Mac G4 dual processor machine. What can be done?

Firefox 3.6.x is the last version available from Mozilla for PPC Macs.

Late 2011 MacBook Pro 2.4GHz Quad-core Intel i7 Vs Latest Release

Hi Guys I own a 2011 2.4GHz Quad-core Intel i7, 8 gigs of ram and 500 SSD. I've a photographer and tether my camera to the computer to shoot. I feel the performance is good and everything is on order. Wondering if upgrading to the latest release if going to see a signifant change in performance. I generally don't edit on my laptop so not sure what the retna display does for me.
Thanks!

(1) On my three 10.9 Macs, upgrading did two very obvious things:
• removed some useful features like the ability to set individual notification audio tones for different chat buddies and collaboration via iChat Theater. (These features are not supported in OS X 10.9's Messages app that replaced iChat.) There may be changes I do not like in other apps, too, but these are two that I noticed.
- and -
• slowed my machines down as compared to OS X 10.8, particularly on booting, opening apps, and other CPU/System interactions. The amount of slowing varied by machine, with my old 13" MBP being nearly unacceptable. My i7 MBP is not nearly so bad, although the the difference is noticeable, perhaps 10% vs almost double boot time on my old 13".
(2) To determine if upgrading will be a problem on your system, I suggest that you:
• make a current Time Machine backup
• configure  > System Preferences... > Time Machine to "OFF"
• upgrade Mac OS
• use your Mac long enough to see if you like the change
(3) If you want to keep the upgrade, turn Time Machine backups back on and continue using the new OS.
(4) If you don't like the upgrade, recover your system from your Time Machine backup.

After their recent upgrade Facebook no longer works for Firefox version 2.0.0.20, what is the most recent version of Firefox that will function with a Mac G3 running OS 10.3.9?

Facebook (FB) recently restructured their website. After logging on to my FB homepage, some of the graphics are garbled and I am no longer able to post status updates, comment on friend's status updates or pictures, or post pictures using Firefox version 2.0.0.20. I would like to know if there is a newer version of Firefox that will function with a Mac G3 Blue and White desktop running OS 10.3.9 which will be compatible with the new FB? I would upgrade my computer, but have 22+ years of business and tax records that will not function with the newer Mac OS.

I just upgraded to iMovie 10.0.1, latest release and need to move my projects and events to an external attached hard drive. i do not see any hard drive icons in this release. How do I do this?

I just upgraded to OSX Mavericks and also the lastest release of iMovie. The version says 10.0.1, but is it the latest release as of 10/14/2013. I need to free up disc space on my iMac hard drive and move the contents of iMovie libraries to an attached external drive already functioning on my system. I need to move both events and projects and keep all intact and related. I have seen disc drives in the previous version of iMovie, but I do not in this one. How do I move these items? I am in desperate need for disc space.

You can create a brand new Library under File Menu>Open Library>New...
Create the new library on the external hard drive. Then drag all the Events/Projects folders into that Library. Close the Library, quit iMovie 10.x. Now test the new Library by opening iMovie again and see that all the Events/Projects are there in the New Library. You can now safely delete or close the exisitng Library file as those are now duplicates of the real Library sitting on the external hard drive.
Another way to do this is find the exisitng Library file, and simply drag it to the external hard drive in the Mac Finder (disk to disk copy of the Library file, by drag and dropping). Then go back into iMovie, File Menu>Open Library>Other... then naivgate out to the external hard drive and choose the Library you moved within the Finder.
The new iMovie 10.x is much more friendly to use the Finder to run and gun and move stuff at will. It used to be the case the Library file had to be completely managed within iMovie and doing Finder copies would break them. Now it's more flexible in that it works the way most people used to think it should work (doing drag and drop in the Finder)

Looking for 64 bit version of firefox, pre-release or Beta ok

I have Win7 Pro 64bit. Was having issues with continuous crashing of flash. I installed Adobe Flash Square version10 64bit with Firefox version4, reduced # of flash crashes.
When firefox pushed out version 5, I installed it & the browser kept dragging/crashing all over again. looked up Adobe Flash Square to see if any info avail, Adobe had Adobe Flash Square version11 64bit, so I uninstalled version 10 prior to installing version11 per Adobe instructions. Although it has helped, it is not where it was prior to installing Firefox 5.
I have tested Firefox 5 with the current Adobe Flash 32bit release as well, and what can I say, it's not work the effort on my 64bit system. for some reason this combo maxes out my cpu (2.8 dual core) & memory (4 gb + virtual), causing me to hard boot my system.
I understand Firefox devs are working on a 64bit version for Windows. I would like to volunteer to test it. I have many years of SW design & QA experience so any bugs I find I will fully document.
The 64bit version of IE works well with the 64bit Flash, lots better than 32bit version, but I prefer to use Firefox or Chrome (I often utilize both simultaneously, each on own screen).
Please let me know if a 64bit version of Firefox is available (pre-release/beta ok) & if it is not is there an expected availability date?
Thank you in advance,
Verta Tannehill

Nightly is a pre-release testing version of Firefox: bleeding edge and not necessarily stable. It is Firefox -- a rose by any other name, and all -- but it is buggy, as all testing software is (I'm using it right now). New Firefox versions are born from Nightly, so when a 64-bit version of Firefox is released, it will have come from Nightly development. Use it for general browsing and send feedback (Tools -> Options -> Advanced -> General) and you will be helping to beta test a new baby Firefox.

Firefox requires 10.5. My mac is osx 10.5.8. Why can't I use the new firefox?

The latest firefox requires osx 10.5. My mac is 10.5.8 but the latest firefox will not run on my mac. I am allowed to download it but it will not function after I download it. With my present firefox I am denied many functions on various sites, particularly on youtube.

We do not understand what Mozilla Firefox means by Firefox Final Release Channel

We are a university that uses the Blackboard Vista 8 product. In order for our students to complete their courses online in Blackboard, they have to use compatible and certified browsers. The Blackboard vendor has a website detailing which browsers the students should use. The URL is http://kb.blackboard.com/pages/viewpage.action?pageId=75071574. No one understands what the vendor (Blackboard) or Mozilla Firefox means by the phrase "Firefox (Final Release Channel)." Does this mean the latest version of Firefox? If so, why not say the latest version and where did the word "channel" come from and what does it mean? It's not explained anywhere on the Firefox website.

Mozilla has 4 channels. In order of less to more secure and stable: Nightly, Aurora, Beta, Release.
On the page you reference, "Final Release Channel" refers to Mozilla's "Release". These are versions that have been completed and "pushed" out for download by everyone. The most current version is always available at https://www.mozilla.com/en-US/firefox/fx/ (currently, Firefox 6.0).
There are only 2 currently supported versions: Firefox 6.0 and Firefox 3.6.20.
*All other versions have stability and security issues that will not be corrected, but are corrected in the updated versions, as they are released.
Other download links:
*Current version (now version 6.0): http://www.mozilla.com/en-US/firefox/all.html
*Older supported version (now 3.6.20): http://www.mozilla.com/en-US/firefox/all-older.html
According to the chart on the page you referenced, your students should be using Firefox 3.6.20 (Firefox 3.5.x versions are no longer supported or updated).
The certified/compatible classifications are Blackboard's determination.
'''Firefox Portable''' 
If your students wish to use the most current version of Firefox for their everyday browsing and use a Blacboard compatible version for use only with Blackboard activities, they can have both on their systems by installing Firefox Portable (not produced by Mozilla):
*Firefox Portable installs in a separate folder on your hard drive so that it does not interfere with your current version Firefox settings or personal information (bookmarks, passwords, etc.). Add-ons are also kept separate.
*You can also install Firefox Portable on a USB/thumb/pin/jump drive.

After restore , uninstall, and reinstall, firefox still crashes on startup on Mac

I had about 20-30 tabs open, but that has never been an issue. Firefox was slow to load an active page, and suggested restore. I clicked restore and tried to reopen firefox. the main page came up and then crashed. I tried again and it crashed again. I opened in safe mode, and it crashed. I uninstalled from the app folder, opened opera to download and reinstall, and it still crashed. That was two days ago. I cleaned everything off the computer related to firefox in the spotlight search, and uninstalled and reinstalled. It opened for a little longer, and crashed again.
