How do I disable "Set as Desktop Background" as an option in Firefox 3.6 running on Mac OSX 10.5?

I'm trying to disable the "Set as Desktop Background" option for Firefox 3.6 in a Mac OSX 10.5 environment. I have a default image that I want as the background on my desktop and I don't want it to be changed.

I belong to a graphic site dreamies.de and my images are disappearing from there since I right clicked on what I thought was set as desktop background. There was another entry under it that said block images from dreamies.de. That is the one that I clicked on by accident and no one knows how to reverse it. Does anyone here know how to reverse it? I was using firefox 3.6 beta 3 when this happened. I am now on firefox 12.
I already tried right-click the page, choose View Page Info, then click Permissions. The first item is the site-specific permission for images and you should be able to reset back to the default here. This did not work.
I also tried right-click View Page Info and click Media. Click the first image on the list and observe the Block Images checkbox above the preview at the bottom. Arrow down the list until you come to a site that is blocked and unblock it. There was no unblock just a delete, so I deleted it. This did not work either.
I know it is a firefox issue because the images are all there when I log in using Internet explorer, but on firefox there are many of my images missing.

How can I disable setting a pass code?

How can I disable setting a pass code? If the students figure out, they are able to set it up.. they will! Help!

Disable restrictions, then re-enable such. You'll be prompted for a new passcode.

Setting the desktop background image via Powershell

UPDATE:
I found the solution that addressed my problem, which I posted in a post below. Keeping the original post for Internet historical reasons as I the hope this helps someone else later on in their search for a solution.
===============
I have Bing'ed and I have Google'd and I haven't found a solid answer to setting the desktop wallpaper programmically. I am trying to do this via PowerShell, but I would be happy for any other language flavor or application to work.
Below is the code I have tried to set the desktop background image. This has been scrounged from a few sources across the web. This solution works 25% of the time and I haven't figured out what the cause for success or failure of the execution. Or maybe
it's neither, but waiting for Explorer to refresh. The only way to see the change 100% is to log out and log back in.
I am running Windows 8.1 btw.
Thank you for looking.

Great news! I found the solution and all props and credit goes to
jsd1982 of the XKCD comic
forum from a post he made in 2007 and some deep search kung-fu Googling on my part. Here is the
direct link to the post.
This solution has worked for me 100% of the time on Windows 8. The only gotcha I found (minor detail) was when setting this process to run as a scheduled task, I had to run it as elevated privileges for the code to compile in memory. Running this function
from PowerShell at the command prompt was fine.
NOTE: The code below is a slight trimmed down version posted by jsd1982 to just set the desktop wallpaper. I removed the image fetching from the Internet and the color inversion.

How can I disable the "go to last visited slide" option in captivate?

Can anybody tell me how can I disable the "go to last visited slide" option in captivate so that every time when i launch my captivate file from a LMS, it WILL NOT go back to the last visited slide? I know that Lectora has a checkbox for this but i can't seem to find it in Captivate.

Are you deploying on a LMS? In that case check the option 'Never Send Resum Data' in Preferences, Quiz, Reporting, LMS Customization Settings.
If you are not deploying on LMS, check if Self-paced Learning is disabled in the TOC?

Hello! Tried unsuccessfully to restore my MBP, running the Mac OSX Lion, to factory settings. I keep getting the "can't download additional components for the Mac OSX Lion" error when reinstalling the OSX Lion. Any tips on how to resolve this problem?

Hi
Given that your answer to 1. is 'pre-installed' and 3. is 'No', I think the only thing to do is to take it to an Apple store (ideally the one you bought it from) and have them reinstall it for you.
The intended solution in cases like yours is that you should be able to reboot and install even a wiped disk by using Apple's servers over the internet (you do this by restarting with 'command-r' and choosing 'reinstall Lion'). However if this isn't working for you then you need to get the store to do it. Don't let them fob you off with 'go home and try again'. Have them do it in the shop (you're still covered by Applecare warranty so it should cost you nothing save the inconvenience of the trip and possibly leaving the machine there while they fix it).
A reinstall should leave all your own personal data and programs in place.
Note for future: when you get it fixed, first thing to do is buy a cheap external drive and start keeping a backup (either Time Machine or clone with Carbon Copy Cloner).

Firefox 4 requires at least OS X 10.5 and an Intel Mac. You can get the latest version of Firefox 3.6 which works on OS X 10.4 from http://www.mozilla.com/en-US/firefox/all-older.html

Is there a way to completely disable tabs (removing all tab related menu options) for firefox 10?

Is there a way to completely disable tabs (removing all tab related menu options) for firefox 10. I hate tabs and recent changes to the menus make incorrect selection of 'open in new tab' when what I want is 'open in new window' a common and unwelcome occurrence.

You can hide menu items and move them up / down in the menu with the Menu Editor extension. <br />

How do I set the desktop background to automatically change every so often?

I had my desktop background set to change every five seconds, with the photos coming from a folder in my iPhoto files. I then made a new folder of background pictures in iPhoto, but when I switched to them and tried to make it "change every 5 seconds", or 1 minute etc., it would not change. I then reverted back to the original group of files and it STILL wouldn't change, even though it had been doing so for the many months that I had been using this set of background photos before.
I have clicked on "change every 5 seconds" and "random order", but for some reason I can now only change the pictures manually by clicking on them in the right hand pane of the system preferences window. Please can someone tell me how to make them change automatically again...?

Have you tried restarting your computer and attempting it again?
Sorry if this is a dumb question, but a lot of people run their machines 24/7 and sometimes a little reboot helps.

How can you disable "set desktop picture" from the finder contextual menu

I teach high school. And MUST find a way to keep my students from changing their desktops.
First I basically got rid of Firefox when it had that feature in the Tiger days.
Then for Leopard I had to create dummy "locked" Safari Desktop Picture files for all my user accounts so the kids couldn't use Safari to set their desktop pictures.
NOW I discover (maybe this was here before) Snow Leopard lets you change the desktop right from the Finder itself! Just right click on any image file and the contextual menu will give them the option to "set desktop picture".
Come on Apple, every educator I know has complained about what a distraction and constant battle images are for students who use computers. While not all students are inappropriate, quite a few are...meaning no one can be allowed the privilege. Why is this such a huge battle to try and lock down? Please allow Parental Controls or Server managed preferences to keep our students from being able to change their desktop pictures, ever, at all, from anywhere or any program.
Does anyone know if this is even possible?

The only way (I have found) to shut down using Safari's "Use Image as a Desktop Picture" feature is to create a bunch of blank documents that the users have no permission to change (i.e. set permission to only allow, say YOU to read it and no access to write to it for anyone)
Create a number of these blank documents and rename them
Safari Desktop Picture.jpg
Safari Desktop Picture.tiff
Safari Desktop Picture.gif
Safari Desktop Picture.jpeg
Safari Desktop Picture.png
(you get the point....come up with as many .3 extensions of photo files that you can think of)
Put these locked and unchangeable files into the following directory of each of your student accounts
Macintosh HD/Users/~User Name/Library/Safari/
What this does is create a bunch of dummy files that will "block" Safari (or the system or user) from trying to replace them. Even though the right click comman will still be there, Safari will not be able to put the picture in the correct part of the system for it to be used as a Desktop Picture.

How do I change what the desktop background is for new desktops?

I am on OS X Mavericks and I want to change my desktop background so that every new desktop I create has that background, but whenever I change the background, it only changes the background for the desktop I was currently in and all new desktops I create still have the old background. How do you change the background for new desktops?

Create a new Desktop and activate that desktop.
Control click to open the contextual menu>>Change background.
When it opens System preference/Desktop&ScreenSaver but takes you back to Desktop #1, simply drag the SysPreference window to the new Desktop to make the change. You can do this by mission control .

How do I change the PS desktop background to a .JPG or other suitable file format of my choosing?

Greetings,
I asked this question a couple months ago and never really received a satisfactory answer. Maybe Adobe holds these secrets close to the vest.
What I would like to accomplish is changing my PS desktop background so that every time I open PS it has a background that I have chosen. (Yes I know you can change the black and grey in the preferences panel) What I want is not necessarily in the preferences panel, unless I'm missing something altogether.
Now here I'm adding a screenshot of a fairly well known PS user CB (who is especially good at 3D) who has his background basically the way I would like mine. If anyone can tell me how to accomplish this thank you!
Sincerely,
Jim
What I'm looking for is something similar to the dark blue background. I have a JPG file similar to this that I would like to use. Now I was able to change the splash opening screen in Lightroom, so I imagine the fix is something similar.

Thanks,
That did work and it's the same as the frame in the sample I provided. Unfortunately not what I wanted. I guess I need to be much more specific. I would like to change the background to look similar to what that sample is, AND be able to have PS as an application that's on top of my desktop and not take up the entire desktop. (which is what happens if I break out the application frame) Probably not something that is doable. I was hoping that similar to changing the Lightroom Splash screen I could change the PS desktop background to something of my choosing other than black or shades of gray. Oh and I am on an iMac.
Thank you again Warunicorn for you help.

Setting up desktop background from iphoto resets after restarting my Mac OS..

Hello,
I have the Mac Os X 10.7.3 version on 2.3 GHz Intel Core i7 processor. I use Iphoto '11 version 9.2.3. My iphoto library shared on /Users/Shared/Ress.sparseimage and it's formatted as Mac OS Extended (Journaled). Two users are using same library and we have no problem while sharing this library.
The only problem occurs when I tried to set up the desktop background from iphoto. When I change the background from iphoto application and restart my computer, the desktop background resets to Andromeda Galaxy.
The reason it resets the background to Galaxy because the volume that contains shared library starts slower. I know this for sure because when I check the Devices section from Finder as soon as the computer starts I can’t see my shared volume on Devices and it takes up 5 or 10 seconds to appear in there.
In my opinion, somehow late launch for this shared volume changes the background’s path to /Library/Desktop Pictures and the first picture in there Andromeda Galaxy.jpg.
We can fix this problem by copying the picture to the path /Library/Desktop Pictures. But unfortunately this solution is very basic and will not satisfy me because I don’t want to copy my pictures from one path to another every time I want to change the background. That’s very frustrating.
I would like change my background from iphoto application. In fact when I use iphoto without sharing and setup the background from iphoto application, I don’t face this problem. This problem only occurs when I share my iphoto library on a volume as a sparseimage.
Best Regards,
HB

Just grab a bunch of photo's you want and place them into a new folder in your User/Pictures named desktop pics or something.
Then you can drag and drop copy certain ones from the shared iPhoto Library.
I keep my desktop and iPhoto Libraries seperate, iPhoto is personal and desktop pictures are just that. No need to waste space in iPhoto as I have over 680 desktop pictures and about 8000 iPhoto pictures, so I don't want to overload iPhoto anymore that it is already.
Once you get large enough desktop pictures the matter becomes mute, just rotate them every 30 or so minutes and it toss in a few new ones from iPhoto when you wish.
If you didn't know, you can point the system preferences > desktop pictures at a new folder in your Pictures folder, there is no need to use the iPhoto Library or drop them into /Library/Desktop Pictures, this is rather risky to be messing inside that folder, in fact in 10.7 Apple has made it invisible to stop people from messing around in there.
Just click the little "+" sign to add a new folder in System Preferences > Desktop & Screensaver preferences.

How can I disable the white image background on Transparent PNGs? (After Firefox 15)

Hello.
I understand that after the Firefox 15 update, transparent images have been given a white background (like in older versions). I personally prefer the dark-grey background. Is there any way to disable the image's background?
Please see this image: http://i.imgur.com/0suFk.png
Perhaps using the about:config module there is an option where I may disable the white background? Thanks.

Thanks for your feedback. I made a restartless add-on that will revert the behavior of standalone images to be rendered against the grey background.
https://addons.mozilla.org/en-US/firefox/addon/transparent-standalone-imag/
You can install this add-on and then it will all happy time :)
