How can I delete my entire History file, without doing it one site at a time?

I am able to delete a given site in my History file by right-clicking on it and indicating to delete it. How do I erase the entire file when it is no longer of any use to me?

You can delete the places.sqlite file to remove all history.
Firefox will use the most recent JSON backup in the bookmarkbackups folder to rebuild the bookmarks.

How can i delete duplicates photos in iPhoto without doing it one by one? Thx

how can i delete duplicates photos in iPhoto without doing it one by one? Thx

These applications will identify and help remove duplicate photos from an iPhoto Library:
iPhoto Library Manager - $29.95
Duplicate Annihilator - $7.95 - only app able to detect duplicate thumbnail files or faces files when an iPhoto 8 or earlier library has been imported into another.
PhotoSweeper - $9.95 - This app can search by comparing the image's bitmaps or histograms thus finding duplicates with different file names and dates.
DeCloner - $19.95 - can find duplicates in iPhoto Libraries or in folders on the HD.
DupliFinder - $7 - shows which events the photos are in.
iPhoto AppleScript to Remove Duplicates - Free
PhotoDedupo - $4.99 (App Store) - this app has a "similar" search feature which is like PhotoSweeper's bitmap comparison. It found all duplicates
Duplicate Cleaner for iPhoto - free - was able to recognize the duplicated HDR and normal files from an iPhone shooting in HDR
Some users have reported that PhotoSweeper did the best in finding all of the dups in their library: iphoto has duplicated many photos, how...: Apple Support Communities.
If you have an iPhone and have it set to keep the normal photo when shooting HDR photos the two image files that are created will be duplicates in a manner of speaking (same image) but the only duplicate finder app that detected the iPhone HDR and normal photos as being duplicates was PhotoSweeper. None of the other apps detected those two files as being duplicates as they look for file name as well as other attributes and the two files from the iPhone have different file names.
iPLM, however, is the best all around iPhoto utility as it can do so much more than just find duplicates. IMO it's a must have tool if using iPhoto.

How can I delete the photos or files in my iCloud storage that is no longer needed?

How can I delete the photos or files in my icloud storage that is no longer needed?

Explain how it didn't work and what you are trying to delete. Since icloud doesn't store photos except for those in a backup (then delete the backup); photos in photo stream do not count towards your storage limit.

How can i deleted the entire entries of my calendar

I noticed that i've multiple entries in my both macbook pro (Lion OS) and iphone 4. So these what I did to solve the problem.
1. Using my iCal from my MBP to delete all the multiple entries.
2. Syn my iphone 4 and selected the calender and click on iTune INFOR on ADVANCED and click "Calendars" (Replace information in this iPhone - During the next sync only, iTune will replace the selected information on this iPhone with information from this computer."
3. Nothing happened.
4. Syn once again - Still nothing happened.
So i'm enquiring how can I delete the entire calendar entries from my iPhone so the next time syn it will syn with my iCal.
Pls advice, or there's a better way in solving the problem.
Thank you.

DEFAULTY CITY? CALENDAR? HUH?
I am not quite sure what you are asking, but there's this:
Your location for time purposes is set in System Preferences, Date & Time, Time Zone tab.
If you are using iCal, there is a Time Zone option in iCal Preferences, Advanced.

How can I delete the Threat History from VZ Protect on my Samsung S4

How can I delete the Threat History from VZ Protect on my Samsung S4

Remove Verizon Protect or disable it if you cannot remove it and install a reputable anti virus / anti malware application from Google Play. I would use something along the lines of Lookout Mobile Security or AVG mobile, or Avast to name a few of them. There are others that work very well and use very little system resources to do it. I have used all of these and Lookout seems to work the best for me.
Verizon Protect gives a lot of false positives on things

How can i delete the masters of iPhoto without losing my photos

Mac Book Pro (Mid 2012) 13 inches
256 Solid State Start up Insert in DVD Drive
1T Hard Drive in reg slot
16 GB Ram
Mavericks 10.9.4
iphoto 9.5.1
I am currently keeping my iPhoto library on my 256 SS Main Drive of my MacBook Pro.
How can I delete the masters of iPhoto without losing my photos in the main iPhoto display library and all their masters and edits.
I take loads of photos and import them and then will keep only 5% of the ones that I import. As a result I have a masters folder of over 50GB and actual photos that take up less that 5GD. Is it possible to delete the master folder without losing all the photos and without having to pain stakingly go through every folder and pick out from literally hundreds the ones that i kept and edited. How do I reduce the size of the masters just down to the ones that I have kept and not every single photo and video that I imported in the history of my iPhoto experience.
If I delete the master folder will all the photos and their edits be deleted.
If so, is there a way to just delete the masters that are no longer in the iPhoto library, while keeping the masters and edits of the ones that I clearly want to keep because they are the ones that I did keep.
Why do they keep the masters of photos that I clearly deleted and emptied the trash on.
I like to maximize space and this would help a lot to clear up for me. Thank you.

All the 5000 photos that reappeared after repair today were from my canada mega event, but for some reason it did not do it for all the other mega events. It is a start but not complete.
Try the rebuild to recover more lost photos.
If "rebuild" with iPhoto does not recover more lost photos, rebuild with iPhoto Library Manager as described by Old Toad in this thread, but rebuilding with iPhoto Library manager will not recover your projects like cards, bilks, slideshows.
Re: iPhoto glitch with retained masters https://discussions.apple.com/message/26354337#26354337
Mostly the way I organize all my photos is that I make a folder for each country I visit. i.e. New Zealand Folder, Canada Folder, India Folder; and at the same time, any photos that I import I delete directly from new imports and just keep the ones i want and then i go up to events and move the latest imported event into a mega event for that country and so they all get joined in a sense.
As a workaround, merge the events right after importing, before you start deleting photos. And empty the trash always before merging projects.
You might consider to use albums instead of events for your country lists. I simply use the events as basic containers. One event for each day of shooting photos. I found, that smart albums and searches are quicker in iPhoto and Aperture, if the events are smaller, also browsing is easier, if the events are not so large.
You can merge albums and remove photos from albums without the problems mentioned above.

I try to open I photo and I get the message, your iPhoto library is damaged...please restore from backup. But i din't made backup copy. How can i delete previous library and work wrom the new one?

Try this (assuming you're using iPhoto 12): make a temporary, duplicate copy of the library and try the three fixes below in order as needed:
Fix #1
delete the iPhoto preference file, com.apple.iPhoto.plist, that resides in your Home/Library/Preferences folder.
delete iPhoto's cache files that are located in your Home/Library/Caches/com.apple.iPhoto folder.
reboot, launch iPhoto and try again.
NOTE: If you're moved your library from its default location in your Home/Pictures folder you will have to point iPhoto to its new location when you next open iPhoto by holding the the Option key. You'll also have to reset the iPhoto's various preferences.
Fix #2
Launch iPhoto with the Command+Option keys depressed and follow the instructions to rebuild the library.
Select options #1, #2 and #6.
Fix #3
Rebuild the library using iPhoto Library Manager as follows:
Using iPhoto Library Manager to Rebuild Your iPhoto Library
Download iPhoto Library Manager and launch.
Click on the Add Library button, navigate to your Home/Pictures folder and select your iPhoto Library folder.
Now that the library is listed in the left hand pane of iPLM, click on your library and go to the File ➙ Rebuild Library menu option
In the next window name the new library and select the location you want it to be placed.
Click on the Create button.
Note: This creates a new library based on the LIbraryData.xml file in the library and will recover Events, Albums, keywords, titles and comments but not books, calendars or slideshows. The original library will be left untouched for further attempts at fixing the problem or in case the rebuilt library is not satisfactory.

How can you delete songs off the ipod without deleting songs off your itunes library?

How can you delete songs off the ipod without deleting songs off your itunes library? My son's ipod automatically synced all the songs in my library to his ipod which he now wants to get rid of. Is there a way to delete them all without me having to erase my library?

Do not select the songs to sync, then sync.

hello, the addons manager is exactly the right place to look for it. please try disabling the addons that are listed there one-by-one (a restart of the browser might be necessary after each step). maybe one of them is bundling this kind of adware.

How can i delete an event on ical without notifying

Hello
how can i delete an event on ical without notifying. All I want to do is delete the event and not notify anyone.
Thanks

I was just experiencing this problem on Mountain Lion. The calendar I wanted to delete was on iCloud. So, I logged into iCloud from a web browser, and selected Calendar. On the current incarnation of iCloud Calendar the calendars are listed on the left. I selected the "Edit" link at the top of that list and chose delete. It indicated that the items would be deleted, but there was nothing about notifications. Then, when I went back to iCal on my Mac, I selected the calendar to be deleted, right clicked, and slected refresh...
... gone.
It probably would have disappeared on it's own eventually. I'd be curious to see if theis works for others, so please confirm.
Good luck.

TS1424 I downloaded a song that I purchased from the ITunes store, but the song does not play properly. How can I re-download the same song without having to purchase it a second time?

I downloaded a song that I purchased from the ITunes store, but the song does not play properly. How can I re-download the same song without having to purchase it a second time?

I could not find an option to "report a problem".
Log in to the Store. Click on "Account" in your Quick Links. When you're in your Account information screen, go down to Purchase History and click "See all".
Find the item that is not playing properly. If you can't see "Report a Problem" next to the entry, click the "Report a problem" button. Now click the "Report a Problem" link next to the item.
(Not entirely sure what happens after you click that link, but fingers crossed it should be relatively straightforward.)
