Can I safely delete this file? \Application Data\Mozilla\Firefox\Profiles\cqzz0psd.default

This has been identified as a Dealtime tracking cookie by Advanced System Optimizer, and a box popped up, led me to this file extension and highlighted the file. I'm just not sure what to do next. I don't know if it was prompted by a Web site or not. If so, I have no idea which one, as several windows were open.

'''No, do not delete that folder.''' All your bookmarks, customizations, saved passwords, etc., are in there.

Firefox is creating endless copies of C:\Documents and Settings\Catain Kirk\Local Settings\Application Data\Mozilla\Firefox\Profiles\afbrfhnj.default\Cache ... how do I stop it

I just installed 9.0.1 and it continually creates copies of C:\Documents and Settings\Catain Kirk\Local Settings\Application Data\Mozilla\Firefox\Profiles\afbrfhnj.default\Cache ... how do I stop it !!!
I'm running Windows XP Version 5.1 SP3.

Hi,
That is the disk cache of Firefox, where contents of loaded pages are kept for faster retrieval and it also helps to conserve bandwidth. To disable this: '''Tools''' ('''Alt''' + '''T''') > '''Options''' > '''Advanced''' > '''Network''', check (tick) '''Override automatic cache management ''' and put the value at zero.

Is there a way from where I can restore my profile from a back-up that I took from a folder (e.g \Local Settings\Application Data\Mozilla\Firefox\Profiles\)

Before re-installing Firefox 19, I mistakenly took backup of my profile from a folder - C:\Documents and Settings\garan14\Local Settings\Application Data\Mozilla\Firefox\Profiles and not from C:\Documents and Settings\garan14\Application Data\Mozilla\Firefox\Profiles.
While installing, I selected "Delete the old profiles" option and I don't see any old profile folder under C:\Documents and Settings\garan14\Application Data\Mozilla\Firefox\Profiles.
However, I have a lot of important data saved under that profile which now has got deleted.
Is there any way I can still restore the data from old profile? (P.S.: As mentioned above, I have a back-up of profile folder which resides under Local Settings folder)
I am in a desperate need for the help. Pls reply as soon as possible.

i have some problem. i delete firefox profile and i cannot use mozilla right now. can you help me ? thank you

File:///C:/Documents%20and%20Settings/user/Application%20Data/Mozilla/Firefox/Profiles/8ylcbvzh.default/extensions/toolbar

whenever i try to run internet through mozila the following remarks come on the screen
file:///C:/Documents%20and%20Settings/user/Application%20Data/Mozilla/Firefox/Profiles/8ylcbvzh.default/extensions/toolbar
pl help me to sort out this problem

The Ask Toolbar is causing that in the Firefox 3.6.13+ versions. Uninstall that extension.
There are a couple of places to check for the Ask toolbar:
* Check the Windows Control panel for the Ask Toolbar - http://about.ask.com/apn/toolbar/docs/default/faq/en/ff/index.html#na4
* Also check your list of extensions, you may be able to uninstall it from there - https://support.mozilla.com/kb/Uninstalling+add-ons

ESET NOD 32 cannot scan past this point. I keep getting stuck at 56% at the following; C:\Documents and Settings\Owner\Application Data\ Mozilla\Firefox\Crash Reports\Pending. Is this a problem with NOD32 or with Firefox? Thank you.

I ran into a glitch on my system that I tried to fix myself. My NOD32 was always showing the yellow warning circle as my protection status when I started my computer. I tried to fix this every way I new how.
Then I started to get pop ups asking me to fix and then send system error reports to Windows. Some stating they were '''''critical.''''' So I sent NOD32 the e-mail below.
'''Me:''' I cannot seem to run a complete system scan. I keep getting stuck at 56% at the following point. C:\Documents and Settings\Owner\Application Data\
Mozilla\Firefox\Crash Reports\Pending
I also keep getting messages to send error reports to Microsoft constantly. I also have this code C:\pagefile.sys-error opening
Thank you for your assistance.
'''Their solution:'''
Based on the information you provided, we recommend that you upgrade to latest version of ESET NOD32 Antivirus and see if this makes a difference.
Please click or copy/paste the following ESET Knowledgebase article into your web browser for step-by-step instructions:
'''Me''' : I did as they requested and am fully upgraded and licensed with their new edition.
Ran a new scan same problem.
I sent them a new e-mail but now wonder if it is a Firefox issue as, C:\Documents and Settings\Owner\Application Data\
''Mozilla\Firefox\Crash Reports\Pending'' this is where the scan stalls.
Any help would be appreciated.
Thank you.

Try delete the files in Pending folder and make the scan again, do not be afraid to delete the files see : https://support.mozilla.org/en-US/questions/679996

I use CCleaner to remove them but when I start Firefox they reappear
Does anyone know what these are?
and what they are for?
Thanks

That looks normal to me. What version did you have before? The layout of the Firefox cache folder changed some time ago so that more files could be accommodated (i.e., to keep performance acceptable because Windows slows down with huge numbers of files in a single directory).

I found a folder named: 89y5ron9.default, C:\Users\x\AppData\Local\Mozilla\Firefox\Profiles\89y5ron9.default , and its over 1.5 GB large, over 25000 files inside. On google this search didnt match to antything. what is it?

after i delete it, it's few days without it and after that it shows again with lots of files and takes a lot of space. I tryed to search on google but without results. My scanning program spends 15 min to check this folder (longer tahn all other parts of HDD)
hope u will answer me
thanks.

That's your browser cache folder. The name is randomized so it's unlikely to come up in a search. If you want to manage the size of the cache folder rather than letting Firefox use the amount of space it likes, you can do that here:
orange Firefox button ''or'' Tools menu > Options > Advanced
On the Network mini-tab, check the box for "Override automatic cache management" to limit the space that Firefox uses.
Or, if your AV software allows you to exclude folders in a scheduled or manual scan, you could exclude the folder. Not sure you really want to do that, though, because sometimes a cached file won't be recognized as malware when you first encounter it, only days later, and it would be nice to clear out undesirable files.

Every time I access the internet through Firefox I get a box with the message "Firefox could not download the search plugin ///c:/Users/Patton/AppData/Roaming/Mozilla/Firefox/Profiles/b2qcb69.default/extensions". How do I get rid of this thing? Thanks

Thanks - I just deleted the ASK toolbar - don't use it anyway. It fixed the issue - thanks again.

How come File : C:\Users\Username\AppData\Roaming\Mozilla\F\Profiles\h4n7abn.default\prefs.js still registers as infection even though uninstalled Firefox?

Already asked but at the time did not register to see if any reply forthcoming, so here is the simple question again:
"C:\Users\Username\AppData\Roaming\Mozilla\Firefox\Profiles\h4nh7abn.default\prefs.js" keeps coming up on my computer as a malware item even though I have completely uninstalled Firefox.
How can this be?!?
I uninstalled all Firefox remnants with a good uninstaller. Re-booted. I've also run scans, including the JRT scan recommended on another mozilla support page, yet it still keeps coming back as though Firefox is still on my computer, even in relation to the "JRT scan"... This is weird...what to do?
--Avast antivirus, Malwarebytes Anti-Malware, Hitman Pro, JRT scanner, CCleaner, etc., installed, Vista - 32 bit.

Sounds like a false positive.<br />
The prefs.js file only stores modified prefs and no code (data) that can run and be harmful that way.
It is usually best to exclude the Firefox profile folder from scanning to prevent such software from corrupting files in the Firefox profile folder.

Which files can I safely delete in my Pictures Folder/ iPhoto Library

Hello
Thanks in advance for any advice on the following. I am trying to free up some space on my Macbook Pro hard drive. In the Pictures/ iPhoto Library folder, I seem to have a lot of duplicates. At this folder level, I have series of sub folders with years 2002-2006 listed, and there is also a folder titled data, which also has subfolders 2002-2006. Can I safely delete one set of folders without losing my pictures?
Thank you
Jonathan

Johnathan:
In a word, NONE. Those are all necessary item for the operation of the library. Those files in the Originals folder are obviously the originals. Those in the Data folder are the thumbnails iPhoto uses to display in the main library window. The Modified files are those that you've editied, rotated, etc. To do any moving, renaming or editing of files directly from the folder is tantamount to committing the cardinal sin of iPhoto: Don't tamper with files in the iPhoto Library folder from the Finder.
What with the low cost of external FW HDs, they are a very cost effective way to protect and preserve important files. As you may know it's recommended to have a minimum of 10G free space for optimum performance of the system and applications. More if possible. You can use Monolingual to remove any language module you don't need (be sure not to select English or American English and DO NOT run any of the Architecture items). I saved nearly 900MB the first time I ran it.
Do you Twango?
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
I've written an Automator workflow application (requires Tiger), iPhoto dB File Backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.

What files can be safely deleted?

I love my 400 MHz TiBook but its 10 GB hard drive is filling up. I have approx. 1.5 GB of free space left. What files that can be safely deleted? Can I delete extraneous printer files, modem files, packages, etc? I use MacJanitor to clean out caches and I don't have any music or photo files that might be causing the bloat. Also, before I delete anything I will back my hard drive up to a FW drive with SuperDuper.

Hi, Fred. You're wise to be thinking about how little free space you have left now, before the operation of your Powerbook is seriously impaired. But rather than just nibble away at the contents of your drive, which will only buy you a small amount of time before you're back where you started, you should be thinking about replacing your tiny 10GB hard drive with a larger one. You could easily get a 60GB drive for $50 plus the cost of shipping, and installing a drive in a Tibook is very simple — a 20-minute job at the outside. Then you'd just start up from the external FireWire drive on which you've cloned your 10GB drive, and use SuperDuper to clone its contents onto the new drive. The whole drive swap and data transfer, including the original cloning, could probably be accomplished in less than two hours. Then you wouldn't have to worry about hard drive space for a long time to come.

What is a .BAK file & can I safely delete it?

In doing a workaround to solve a stutter problem in iMovie 4, my .iMovieProj files got completely out of whack. (Yes, I had more than one .iMovieProj file for my project. That's another story.) I had to go to my external backup disk to retrieve an .iMovieProj file. Because it would be better to keep the entire folder intact, rather than just put the .iMovieProj file into the current folder, I copied the entire project folder to my Desktop.
I deleted the current project folder and moved the Desktop folder into the iMovie folder, so now I have a previous, intact project folder, albeit a bit out of date, but at least all my videos & audios are there.
Anyway, as I updated my project, I noticed in the Movies window I had open on the desktop, that a file: <projectname>.BAK would appear & disappear. The project name was a bit altered. I think the file appeared & disappeared when I did a save, which I now do often.
What's going on? Should I delete this file when it shows again, or just ignore it & let iMovie 4 manage it, as apparently it's doing? On my last save, the file is not there, but it may show up, again. BTW, I noticed that the file decreased in size at one point. It's a small file, now, about 8KB as I recall.

Just let iMovie manage it.
When an application saves a document it's a bad idea to delete or empty the old one first and then write the new one. What if something goes wrong? A power outage or what ever.
The proper way is to keep the old (original) file until the new one has been completely written and THEN delete it. It seems as iMovie keeps the original under the <projectname>.BAK name until the new file is written.

I have an icon on my MAC desktop called disk utility. When I click it on it a message says it is not compatible with this version of OS X. Can I then delete this set of files?

I thought the disk utility icon on the desktop may be related to my old software. I was going to move it totrash but it had over 2000 files and so I did know if it was still being used or could be moved to trash.
What kind of files are in there? Sounds like a carry over from your last system. DiskUtility should only be kept in Utilities with a shortcut in the dock or an alias on the desktop, idealy.

I am running out of memory on my hard drive and need to delete files. How can I see all the files/applications on my hard drive so I can see what is taking up a lot of room?

Either of these should help.
http://grandperspectiv.sourceforge.net/
http://www.whatsizemac.com/
Or search 'disk size' in the App Store.
Be carefull with what you delete & have a backup BEFORE you start, you may also want to reboot to try to free any memory that may have been written to disk.
