Safari Extensions security

Hi,
I've withheld from installing any Safari extensions because I'm unsure of the risk to data security they represent.
I currently use Safari for my online banking (though I'm investigating a more secure method using a bootable LINUX live USB flash drive), and I'm always aware of the fact that extensions, once they are installed, have access to a great deal of the data put through Safari.
Now, I'm not saying that there are any malicious extensions in the official gallery; what I'm merely asking for is a way to understand the potential security risks of extensions more clearly, so that I can make an informed decision.
Also, I'm a Little Snitch user - does anyone know how any given extension (should it be malicious) would reveal its outgoing connections request - would it be as the extension (eg. "Ghostery has requested access to ports blahblahblah"), or as Safari?
Many thanks,
S.

Hi
given that you're considering an alternate boot solution - anything that has the ability to add/remove displayed content from web-pages is probably unacceptable, I'd think. Quick enough to switch extensions on/off though, and with the debug menu enabled, there's a menu command that a keyboard shortcut can be assigned to.
Ok, it's a stretch - since some good safeguards are apparently built-in regarding what extensions can do,

TS3230 Safari Extention "Security 1.0" do not uninstall from the list and is crashing Safari. I cant even open it. I have to turn off the extensions in order to use Safari.

Safari Extention "Security 1.0" do not uninstall from the list and is crashing Safari. I cant even open it. I have to turn off the extensions in order to use Safari.I delete all extensions from the /Library/Internet Plugins and ~/Library/Safari/Extensions except for this extension
WebSecurity.plugin WebSecurity32bit.plugin and WebSecurity.safariextz respectively.
If I tried to uninstall it it crash my Safari and when it reopens, it is still there.
The most anoying is this question for every site. Any help?

Uninstall the whole worthless "WebSense" product.
Any third-party software that doesn't install by drag-and-drop into the Applications folder, and uninstall by drag-and-drop to the Trash, is a system modification.
Whenever you remove system modifications, they must be removed completely, and the only way to do that is to use the uninstallation tool, if any, provided by the developers, or to follow their instructions. If the software has been incompletely removed, you may have to re-download or even reinstall it in order to finish the job.
I never install system modifications myself, and I don't know how to uninstall them. You'll have to do your own research to find that information.
Here are some general guidelines to get you started. Suppose you want to remove something called “BrickMyMac” (a hypothetical example.) First, consult the product's Help menu, if there is one, for instructions. Finding none there, look on the developer's website, say www.brickmymac.com. (That may not be the actual name of the site; if necessary, search the Web for the product name.) If you don’t find anything on the website or in your search, contact the developer. While you're waiting for a response, download BrickMyMac.dmg and open it. There may be an application in there such as “Uninstall BrickMyMac.” If not, open “BrickMyMac.pkg” and look for an Uninstall button.
Back up all data before making any changes.
You will generally have to reboot in order to complete an uninstallation. Until you do that, the uninstallation may have no effect, or unpredictable effects.
If you can’t remove software in any other way, you’ll have to erase and install OS X. Never install any third-party software unless you're sure you know how to uninstall it; otherwise you may create problems that are very hard to solve.
WARNING: Trying to remove complex system modifications by hunting for files by name often will not work and may make the problem worse. The same goes for "utilities" such as "AppCleaner" and the like that purport to remove software.

My Safari Extensions preference page is blank. How do I resolve it? (Safari 5.1.2 on Lion 10.7.2)

I found my extensions window blank back when I used Snow Leopard. I thought Lion and new updates will eventually solve it. But it is still there. I tried everything I can. I tried downloading Safari 5.1.2 and reinstalling it. It didn't work. Then I uninstaled safari using CleanMyMac and then tried installing it from scratch. It didn't work. When I googled I found that deleting some plist file resolves the problem on some older version of Safari. But I cannot locate that plist file on Lion. How can I get back my extensions preference page?

Delete the following items:
/Library/Application Support/SIMBL
/Library/LaunchAgents/net.culater.SIMBL.Agent.plist
/Library/ScriptingAdditions/SIMBL.osax
Log out and log back in.
Make sure you never reinstall SIMBL, as it’s one of the worst articles of crapware on the Mac platform. It’s likely to come bundled with some other modfication that depends on it. If you want trouble-free computing, avoid software that makes miraculous changes to other software, especially built-in applications. The only real exception to that rule is Safari extensions, which are mostly safe, and are easy to get rid of when they don’t work. SIMBL and its dependents are not Safari extensions.

Error while trying to install safari extensions on Macbook Pro Retina

Dear All,
Yesterday I had to re-install Mountain Lion OS on MacBook Pro Retina. Everything went smoothly however after the installation process and updating sytem to the newest possible version, I am not able to install any Safari extensions. I was trying to find any information in the internet about this but so far I am unsuccessful in solving this issue. I am currently running Mountain Lion 10.8.2 and Safari 6.0.1. I would be grateful for any help.
Best Regards,
Jan

Back up all data now.
This procedure will unlock all your user files (not system files) and reset their ownership and access-control lists to the default. If you've set special values for those attributes on any of your files, they will be reverted. In that case, either stop here, or be prepared to recreate the settings if necessary. If none of this is meaningful to you, you don't need to worry about it.
Step 1
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Drag or copy — do not type — the following line into the Terminal window, then press return:
sudo chflags -R nouchg,nouappnd ~ $TMPDIR.. ; sudo chown -R $UID:20 ~ $_ ; chmod -R -N ~ $_ 2> /dev/null
Be sure to select the whole line by triple-clicking anywhere in it. You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up. You don't need to post the warning. If you don’t have a login password, you’ll need to set one before you can run the command.
The command will take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear, then quit Terminal.
Step 2
Boot into Recovery by holding down the key combination command-R at startup. Release the keys when you see a gray screen with a spinning dial.
When the OS X Utilities screen appears, select Utilities ▹ Terminal from the menu bar. A text window opens.
In the Terminal window, type this:
resetpassword
That's one word with no spaces. Then press return. A Reset Password window opens. You’re not going to reset a password.
Select your boot volume ("Macintosh HD," unless you gave it a different name) if not already selected.
Select your username from the menu labeled Select the user account if not already selected.
Under Reset Home Directory Permissions and ACLs, click the Reset button.
Select  ▹ Restart from the menu bar.

New york times updates - safari extension - not refreshing

New York Times Updates Safari Extension seems to have stopped updating it's info. I uninstalled it and then reinstalled it, but it only added a couple of items from several days ago. Is this feed no longer viable? The version on the Safari extensions web site is 0.1, the same as always.

Try emptying the Safari cache more often.
You can do this from the Safari menu bar, click Safari / Empty Cache or Command + Option + E on your keyboard.
If emptying the cache didn't make a difference, go to the Safari menu bar click Safari > Reset Safari.
Select the top 5 boxes, click Reset.
Restart your computer.

My safari preferences/ security screen has changed and no longer addresses cookies. There is now a Preferences/Privacy screen that allows one to delete cookies, although it is harder to do than the older security screen. Was this an update?

My Safari Preferences/Security screen has changed and no longer addresses cookies. Rather, there is a new Preferences/Privacy screen that allows you to manipulate cookies, but it is not as easy to use as when cookies were on the security screen. Was this an update? Has this change affected anyone else? This is strange, because Safari Help still states cookies are manipulated on the Security screen, even though the screen has changed and no longer addresses cookies.

Presuming you're referring to Safari 5.1, yes, it's moved, but I don't see it as being harder. Now you can clear all privacy-related items - cookies, cache and history - with one button, the "Remove All Website Data" button. If you want to work with individual cookies, it's still just one button, the "Details" button. So no, I don't see it as being more difficult.

Cannot Install Safari Extensions

Greetings,
Trying to install an extension on my Safari Version 8.0 (10600.1.25.1)
An extension installed successfully, but after Safari restart its all gone.
Does not matter which extension and how many,
After install I can see extensions in Safari Preferences window, but not after a restart.
I can see newly installed extensions in ~/Library/Safari/Extensions/ folder, the folder has correct permissions and owner.
Even though there are extensions in ~/Library/Safari/Extensions/ , Safari does not "sees" it after a restart.
It seems like this problem is specific to my PC, as I have checked it with other people - they don't experience it.
Please help !

Back up all data before proceeding.
Launch the Keychain Access application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Keychain Access in the icon grid.
Use the search box in the toolbar of the Keychain Access window to search for an item named "Safari Extensions List". If found, delete it. Quit Keychain Access.
Quit and relaunch Safari.

Safari extensions not in color

My Safari browser, toolbar and all icons are grey. Does anyone know if you can install the Safari Extensions someway in which they appear in color ? ie; The Weather Channel, Pinterest, Evernote, etc.
I've seen other browsers/toolbars where the icons were in color, making it easier to find each of the icons when needed.
Thanks in advance for any useful advice and/or solutions.
MacBook Pro 17", using OS X 10.9.4 and Safari Version 7.0.5

If you want to change the color, use Download Firefox
Always good to have a backup browser installed in case you have problems with Safari and can't connect to the internt for help.

Is there a Safari extension (or plug-in) for Acrobat Pro?

Is there a Safari extension (or plug-in) for Acrobat Pro? I use to have one, then when I updated to the new Yosemite operating system, it disappeared.

For Acrobat Pro? I don't really understand. You don't typically *edit* PDFs in a browser.
Note that Acrobat Reader is totally unnecessary on OS X. I'd recommend avoiding it. If you are creating PDFs, or doing advanced features that make it worth spending hundreds of dollars, then Acrobat Pro may make sense, but otherwise, just use Preview.

I can't download from the Safari Extensions gallery

Hi,
*I can't see any download/install buttons in the Apple Safari Extensions page.* I just uninstalled ALL my extensions trying to troubleshoot this and now I can't get them back.
I know there are at least two other issues like this but they're both unanswered and I honestly can't follow how some people claim to have been able to fix it.
Please help! I won't have any choice but to switch to Chrome if I don't get this fixed.
Thanks,
Carlos

Hi,
Open a Fiinder window. Select your Home folder in the Sidebar on the left. Now open the Library folder then the Safari folder then the Extensions folder.
If any of the extensions you have installed are in that folder, move them to the Desktop.
Quit Safari (Command + Q) then relaunch Safari and try the gallery.
If that didn't help, go back to the Extension folder and move the Extensions.plist file to the Trash.
Relaunch Safaari, try agian.

Safari extensions not working

My Safari extensions have stopped working. I am running Safari 7.0.3 on OXS 10.9.2. One day I went on to the internet and my extensions still appear, but are not functioning (my antivirus toolbar is unusable as only half of it is appearing, and my add blocker appears but doesn't actually block apps). I'm not quite sure if this is an issue with my extensions, or Safari, so I thought I would find out if anyone else is having this issue.

May be there is an adware installed.

Cookies options gone from Safari Preferences Security

I have been having weird glitches with Safari for the past few days. I cleared the cache (several times) and went to dump cookies - and all of the cookies-related options seem to be missing. In Safari>Preferences>Security, the middle section of the box that includes options for accepting cookies and to view cookies is not there anymore. In Safari>Reset Safari, the button for Remove Cookies is gone, though the rest of the list appears to be there.
I clean out cookies semi-regularly, and the options were all there over the weekend.
Any thoughts?

We are on Safari 5.1 here, the cookies are in the Privacy pane.
Overwrite/install Safari here, then apply Software Update under the Apple menu to make sure
https://www.apple.com/safari/
Then run ALL the cleaning and maintainance steps of the free OnyX and reboot.
http://www.titanium.free.fr/
Then download the free Easy Find and delete all folders called "Macromedia" (it's your Flash cookies etc)
http://www.devon-technologies.com/files/EasyFind.app.zip
Reinstall your Flash here to rebuild
http://get.adobe.com/flashplayer/
That shoudl clean you out good
If you need more cookie and privacy control, you just have to go with Firefox + Adblock Plus, Ghostery, BetterPrivacy, Click&Clean and even NoScript (drag a temporarily allow all button to the toolbar)
