How can I disable SSLv2 on OS X 10.8.5 server

weaknesses.
Description :
The remote service accepts connections encrypted using SSL 2.0, which
reportedly suffers from several cryptographic flaws and has been
deprecated for several years. An attacker may be able to exploit
these issues to conduct man-in-the-middle attacks or decrypt
communications between the affected service and clients.

How can I disable incesant rambling alarm "The connection to the server was reset while the page was loading" in FF17?

In using FF 17.0.1 in a WinXP/SP3 notebook (Acer) while traveling abroad I get unrelenting rambling and totally inconsequential display alarms "The connection to the server was reset while the page was loading." The page in question looks perfectly fine and there is NO problem whatsoever in its display. The only problem is this annoyingly useless alarm, which forces the screen display to the tab where the supposed error occurred when one is in a different tab -- in a couple of instances, this absolutely unnecessary, forced jump to a different tab has made me lose data being entered in a different tab.
The notebook is extremely lean in its booting process -- no shared DLLs preloaded; no crapware; limited essential start-ups; trimmed unused or irrelevant services. The alarm occurs:
(1) with FF and the OS in either normal or safe mode (i.e., both safe mode, both normal mode, or one safe mode and the other normal mode);
(2) using different Western European ISPs;
(3) using different DNS servers (either default European ones, or manually selected top-tier U.S. servers);
(4) and with a number of different web pages (such as many in sites of news organizations) but not in all pages (for instance, none of the different Google server pages).
The alarm does NOT occur browsing the same pages with either Chrome, Opera or IE.
I have not been able to find a clearly marked entry for such an alarm in about:config, and am weary of start changing alarms settings blindly. The text of this alarm is not found in firefox.exe so it must be in one of its associated libraries. Given that this alarm is COMPLETELY WORTHLESS, especially in its manic wanton conditions, can some one give me an informed opinion on how to disable it? TIA

Thanks for responding, David. Using <Esc> and <CtrlW> might reduce the time in returning to the other tab, but does little when the triggering of a wanton alarm is very frequent. The connections I have used were extremely reliable and fast. I am using at this moment a 54 Mbps WiFi connection that lives up to its ratings in downloading & uploading data; yet, as shown in the attached image, I still get this worthless alarm. I do not know if this problem happens with my regular ISP since I have been using this tiny notebook only when traveling -- will test that once I am back mostly for curiosity, but even then if then the alarm were not triggered this would be of little consolation, since other browsers do not have the problem right now).
As a moderator, I urge you to ask the Mozilla-powers-to-be why there is no way to turn off the alarm with, say, a true/false switch in about:config (mind you, there is still old-versions junk in this config list, so it isn't we are talking about amending the constitution). Complains about this fugly alarm can be traced in the web as far back as 2010 at least. Besides, what is the advantage of the alarm for the average user? When FF users are still posing amazingly basic questions in forums of Firefox or Mozilla support, such an alarm ought to be _off_ by default and should be an option of advanced settings menu. This annoyance shows how much the critical focus on keeping a simple GUI uncluttered by trivial or higher-level messages still needs to evolve for Firefox, which I have used it since it was known a Firebird. Guess will have to switch to Chrome now while abroad.
Happy Holidays

How can I disable prompts for Firefox updates on a Terminal Server (Citrix)?

Does any know how I can disable updates and update prompting in Citrix for Firefox 3.6?
I've got a 3rd party application that has lots of problems in Firefox 4, so I can't upgrade at this time. I just want to stop users from getting this prompt.

Thank you for the quick reply, but I've already tried that, it only affects the one user that un-checks the box. All other users still get prompted.
I'm trying to avoid having to have every single user go through this process.

How can I disable Firefox from automatically opening on system startup on my Mac - unchecking the "open at login" does not work?

We have Firefox 10.o on our Macbook Pro OS X 10.5.8. I prefer using Firefox as my browser but my husband prefers Safari for now because of a long history of bookmarks and saved information he doesn't have time to re-do. He is tired of Firefox automatically opening when we start up the laptop, and even when we uncheck the "open at login" it still opens at login every time. He is about to uninstall it because of this. How can we disable? It does NOT show up in our account on the Mac OS as an application that starts at login, so we can't disable it there.

For those of you running Windows, I found this on another site. (Unfortunately, not before getting totally disgusted and switching to chrome.)
1. click start (or the windows flag button at the bottom left) 2. in the "search programs and files" or the RUN dialog box, enter "msconfig.exe" or "msconfig". 3. That should open the system configuration program. 4. click the "Startup" tab at the top of the opened program. 5. Under the "startup item" column, look for Mozilla firefox. 6. uncheck that one. 7. Click OK or apply. 8. click "exit without restart". 9. you're good to go.

How can i disable imessage from automatically starting up when i turn on macbook air?

how can i disable imessage from automatically starting up when i turn on macbook air? i dont know my imessages to pop up on my laptop when it turns on. But i dont want to disable imessage totally on my macbook.

Welcome to the Apple Support Communities
First of all, check that Messages is closed when you turn off your MacBook. This is so important because, by default, OS X will reopen all opened apps the next time you start your Mac.
Apart from that, when you go to  > Shut Down, or  > Restart, in the window you see to restart or turn off your MacBook, unmark "Reopen windows when logging back in". This will avoid that your Mac opens all opened apps the next time you start the MacBook, so Messages won't start automatically at startup

The windows of the Windows bar are already a form of tabs, so I don't need them in Firefox. How can I disable them completely from Firefox 23?

RE: TABS ARE WINDOWS!
The Windows bar already functions as a tab bar. Those tabs are called "windows." So, I find Firefox tab windows superfluous. How can I disable them completely from Firefox 23? I don't need what is essentially TWO windows bars covering up the entire width of my widescreen monitor's image! I already have a Windows bar at the bottom of my screen and, if I really wanted to, I could change ITS position to the top of the screen, so that it would LOOK like the Firefox tab windows bar. Firefox TABS are, essentially, a superfluous SECOND WINDOWS BAR.
Here are my reasons for why I'd rather use Mozilla's Firefox, than Microsoft's Internet Explorer or Google's Chrome. I love and admire Firefox for Mozilla's intent on good security, for Firefox's Personas add-on, and for Firefox's free use of the Ad-Block add-on which, as you know, has the distinct virtue of reducing screen clutter--the last of which is my motive for wanting to get rid of the SUPERFLUOUS Firefox tabs "windows" bar. I am dreadfully sick of companies forcing miscellaneous bars (mostly representing marketing campaigns trying to sell me something) into my browser (and down my throat) every time I download something. (In case you haven't guessed, I am deliberately referring to your Firefox tabs bar as a "Firefox tabs 'windows' bar," because TABS are WINDOWS!)

Let me clarify even more. The Firefox add-on you mention does not remove "tabs" windows. It only HIDES the "tabs" bar when there is only one "tab" in that window. It DOES NOT end "tabs." It does not turn "tabs" off.
I know this, because, even with the add-on you recommend, the "tabs" bar often re-appears when I open a link, which--for some unknown reason--Firefox defaults to opening in a second "tab" within the same window, rather than putting it in a new Windows bar window. This, of course, disregards what I want to happen.
I want to use my Windows bar to control my windows. I do not want my Firefox browser controlling my windows--which it calls "tabs." Can you tell me how to shut off "tabs?"

How can i disable a submit button and execute submit_action method on click

Good Day,
On my page I have a submit button that execute the submit_action method of the page backing bean that submit data captured on the page into a database and activate another class that send mail at the same time on a click of the submit button,the mail process takes a while before returning back to the page.I was able to disable the submit button to prevent the user from keep click while the process is running but the issue is on clicking the submit button it only disable the submit button without executing the submit_action method of the page backing bean.How can i disable the submit button and execute submit_method of the backing bean at the same time.
Thanks in advance.

I tried this out on one of my pages to see if it works.
First, I added the following JavaScript to my submit button's onClick event:
this.disabled=true; return true;When I clicked the submit button, it was disabled but the form was not submitted.
I deleted the JavaScript from the onClick event and added the following JavaScript to the form's onSubmit event:
var button = document.getElementById("form1:submitButton"); button.disabled=true; return true;When I click the submit button, it was disabled and the form was submitted but the button's action method was not called.
The next thing I tried was to change the onSubmit event code:
var button = document.getElementById("form1:submitButton"); setTimeout("button.disabled=true", 500); return true;This seemed to work. The difference was that I added a 1/2 second delay before disabling the button.
See if that works for you. If not then I'm fresh out of ideas.

How can I disable awesomebar search/keyword suggestions on FF 3.6?

I am on FF 3.6. I'm trying to find a way to disable the AwesomeBar search/keyword suggestions. I have gone through tools -> options -> privacy -> location bar. I have tried setting the location bar set to show only history, bookmarks, or even none, but it still shows keyword search suggestions. How can I disable this?
I have also tried from about:config, setting maxrichresults to 0. Again, that is not what I'm looking for. I want it to show history and bookmarks, but I do not want keyword search suggestions.

I'm pretty sure the poster doesn't want to disable the keyword search functionality. What they want is for keyword searches to work, but just not be displayed (or at least not displayed as the automatic first option) on the list of location bar suggestions when typing a new URL.
In their words, "I want it to show history and bookmarks, but I do not want keyword search suggestions."
That was how keyword search bookmarks worked in FF3.5, if I recall, and I too would like that behavior back. I haven't found any way to train the awesomebar to not show me keyword search bookmarks.

How can I disable iPhoto automatic launch?

Hi,
I do not use iPhoto to import my digital images. How can I disable the automatic launch when I plug my camera or card reader?
Thanks!

Hi Paul,
To do this just open Image Capture, open its preferences and then under the general tab you can select the option of "When a camera is connected, open:"
Just select no application and that should do it.
