Firefox on USB Drive

When I downloaded Mobile using a borrowed Desk Top onto my USB drive, it appears that a copy of the Desk Top version from the borrowed Desk Top was downloaded as well... If I remove that version from my USB Drive will it affect the Mobile version? If not, should I Delete or Uninstall?

Oh, I see. You're talking about a "portable" Firefox that can be moved from one computer to another on a USB drive.
"Portable" Firefox is just a special launcher for the normal Firefox browser that runs on desktop and laptop computers. It includes the full Firefox browser. You should not delete any of the files that it installs on your USB drive.
If you have more questions about the software from portableapps.com, please go to their support page:

After installling Firefox 4, my USB drives no longer worked. After uninstalling, they worked again.

I have a Toshiba Satellite A665. Windows 7. I have been using Firefox 3.6.16 without problems. Updated with Firefox 4.0. My USB drives wouldn't work anymore. Tried using my Nook, Flash drives. My computer just didn't see anything plugged into the USB. I uninstalled Firefox 4.0 and my USB ports worked. Installed Firefox 3.6.16. USB ports worked.

Hi grant862
I seam to be having the same issue. I have a number of Flash cards and a flash card reader, well tow card readers actually. I cant get the cards to mount. I have tried swapping usb cables and card readers. I have tried both readers in all my USB ports (17" Mac Book - 10.5.4). The only way that I can get them to mount is if I plug the cards back into the cam,eras an connect them. I think there is a software glitch somewhere. I don't think its the usb ports as I have tried keyboards and mice connected via these ports with no issue. I don't expect an answer to this, but Grant - if you are still out there - I wanted you to know you weren't alone. I am going to try re-installing the 10.5.4 combi download and see what happens. Oh yes and 'repair permissions' (which I have already done once...) but am beginning to think that this is just a bit like saying a mantra as a way of calming me.
...Ohmmm madhi padhi ohmmm....

Is there a possibility to download files directly to the external usb drive in Firefox for Android?

I have the Android device that support external usb hard drive, when I want to download some files via Firefox there are only two possible "places" where I can put the files - external memory or SD card. It will be nice if there would be an option to save file on ext. usb drive.

Hi Nix_N1:
Yeah I don't know about this and I don't have an Android device that supports USB storage.
What Android device are you using and what operating system (Jellybean? Ice Cream sandwich ?)
I asked the Mozilla QA folks and they said Firefox for Android uses the Android platform download directory so the USB drive *should* show up if it registers properly with Android.
They suggested the following:
# removing the SD card and seeing if it shows up in place of the SD card.
# perhaps changing the following preference (type "about:config" in the url bar without the quotation marks)
''' browser.download.dir'''
will fix it ('''WARNING:untested and unsupported but hopefully this might help''')
Regardless I suggest filing a bug at (I looked but couldn't find a bug that corresponds to this):

I3 window manger & automount external hard disk / usb drive

Hi,
I using arch x86_64 with 3.11.5-1-ARCH #1 SMP PREEMPT kernel + i3 window manager + pcmanfm.
But i'm unable to automount my external hard disk or usb drive.(I have installed gvfs package as well.
Also is there any gui tool to configure keybinding? (something like obkey in openbox)
Please help.
Thank you.

I think you need to look at https://wiki.archlinux.org/index.php/I3#Volume_Manager and the output of man i3

USB Drives Randomly Disconnect and then Reconnect

On my laptop I have a USB drive where I keep all of my data. It is always plugged in while the laptop is in use. However a number of times the USB drive disconnects itself and then immediately reconnects. I get the notification that my Y drive has been connected. This causes problems for my synchronization application that constantly monitors changes on my C drive. I have changed all of the Power options that prevent the drive from powering down when not in use but the problem still happens. This problem happens on all of my USB ports. The external drive is a Western Digital My Passport 2 TB drive. This problem is getting to be a real nuisance. I have only had the laptop for 5 months. In searching the internet there seems to be a lot of people that have been having this problem but I couldn't find a suitable solution. I never had this problem with any previous laptops that used this external drive. The laptop is running Windows 8.1 with 12 GB RAM and a 1 TB hard drive. This is the operating system that was installed on the laptop when I purchased it. Has anyone found a fix for this type of problem? Thanks,Joyce

This is a known bug and Microsoft are working on a fix. They plan to fix this before Firefox 4 reaches release candidate phase.
A workaround is to change a preference in Firefox:
# Type '''about:config''' into the location bar and press enter
# Accept the warning message that appears, you will be taken to a list of preferences
# Locate the preference '''html5.enable''' and double-click on it to change its value to '''false'''
If you do this, remember to set the preference back to true by double-clicking on it again when Firefox 4 release candidate is made available, the bug should be fixed by then.

IPhone 5 iOS 6.1.4 and Windows 7 x64 USB Driver Issues

Been pulling my hair out with this one for the last week or so and haven't had any luck finding anything on the forums or the web regarding a solution short of a full reinstall of Windows 7 which I am not prepared to do at this time; so hoping someone here can shine some light on this for me
I have a iPhone 5 that is updated to iOS 6.1.4 and a recently built Windows 7 64-bit machine. All of my other USB devices function fine (keyboard, mouse, Xbox 360 wireless receiver for Windows, and a Seagate 2TB external USB drive). I've downloaded the most recent version of iTunes, installed successfully and then attempt to plug in my phone to sync. I get the standard Windows *ding* that I've attached a device and 1 of 2 things happens (I haven't been able to determine what causes one reaction to happen versus the other): Windows will successfully install the 'Apple USB Mobile Device Driver' successfully and it will appear under my USB devices in Device Manager. However - iTunes will not recognize the phone and I cannot see it in Windows either. In the 'Devices and Printers' snap-in my iPhone will appear under 'Unspecified Devices' as the 'Apple USB Mobile Device'. The iTunes diagnostics fail to find a connected device so the tests fail. As soon as I unplug the device, the strangest thing happens: Windows will start trying to install a device driver and after a few seconds it will fail stating that the "MTP Device Driver" installation failed because the device was unplugged. iTunes also thrown an error "iTunes cannot connect to this iPhone" throwing error code 0XE8000065 (I've also seen error code 0XE8000085 as well)
After some finagling, I've managed to get Windows to recognize the device under 'Portable Devices' in Device Manager as an "MTP USB Device" using the generic driver. At this point, I've tried updating the driver and manually specifying the Apple USB driver located in the C:\Program Files(x86)\Common Files\Apple\Mobile Device Drivers which updates successfully but then changes the device to "Apple USB Mobile Device" and moves it under the USB Devices in Device Manager; and Windows nor iTunes can see it even still.
I've tried removing iTunes several times and ensuring that all remnants of the installation are gone (registry and folders on the installation drive) and have disconnected all my USB devices short of the keyboard and mouse and still I get the same results. At this point, I'm afraid that a re-install of Windows is going to be the solution; but it's a drastic one (I have a SSD drive where Windows is installed along with all of my games for faster load times/better performance and do not want to have to redownload\reinstall all of them) and I'm not prepared to undertake it at this time, which is why I'm posting here
I've used a utility called USBDeview that sees my phone is connected - so I know from a functional standpoint that my USB ports are good and working. I also know the cable is good too - my daughter's PC (Windows 7 32-bit with NO iTunes) immediately sees the device when I plug it in, installs the drivers, recognizes it as an iPhone and I can then see/browse it in Windows Explorer like I would normally expect. My work PC (Windows 7 64bit, NO iTunes) sees the device just fine as well. I would immensely appreciate anyone that has seen this issue or has any additional solutions I can try.
It's also worth mentioning that I've never used Kapersky antivirus so the UPPERFILTERS value in the registry that I've seen as a solution on some forums is not present on my machine. I'm using Microsoft Security Essentials as my antivirus (no flaming please lol - it meets my needs and is extremely lightweight, which is why I'm using it on a gaming rig) and it's not indicating any issues. I've also tried running iTunes as an administrator (even though my account is a local admin on the machine) and that does not have any effect either.
If there is anything I left out, please let me know; and I thank you in advance!

New Firewire 800 External Hard Drive and how to use old External USB Drive

Hi All,
I have a new LaCie d2 Quadra Hard Disk hard drive 500 GB - FireWire / FireWire 800 / Hi-Speed USB / eSATA-300 on the way, when it arrives I plan to use it as my Time Machine Backup drive with the FireWire 800 connection. I am currently using a Seagate Free Agent USB 2.0 320 GB external drive as my Time Machine disk. The reason for upgrading is the USB drive is slow slow slow! I am not concerned about the data on my old drive and will just wipe it clean using Disk Utility. What I would like to do is use the old drive to archive iTunes 7.7.1 and Aperture 2.0 music and photographs. Can someone give me an idea how to go about doing this?
Thanks!

Hi, yes that will copy the whole iTunes..including everything in iTunes..BUT, as you add to your iTunes on the Main HD, with the ext HD I think you will have to manually update anything added. Or dragNdrop the whole thing again.. You could also locate you iTunes music Library & just copy that across..With images once again find your iPhoto library & just copy that across..L

How do I Install Windows 7 on Mac Book Pro via a Bootable USB Drive

Hi Guys,
I have a Mac Book Pro 13 inch, Early 2011 Processor 2.3 GHz Intel Core i5 (I initially had OS 10.5.8 which I upgraded to OSX 10.9.4 a few months ago).
When purchased it, I installed Windows via Super Drive (that being the only time i ever used the super drive). My Windows got corrupted for some reason 2 months ago. Hence, I removed the windows via Bootcamp to perform a fresh install. I discovered my Super Drive was no longer working.
Thereon I have been trying to install Windows via a bootable USB Drive but am failing to do so. After going through several forums, I have reached the following stage.
1. Created Bootable Windows USB Drive using Windows USB (http://www.wikihow.com/Create-a-Bootable-Windows-7-or-Vista-USB-Drive). Have used this USB drive to install windows on a DELL Computer
2. Bootcamp wasnt creating a partition for windows since no Windows Installation disc was being detected in super drive. (Solved it by downloading Toast Titanium and loading the .iso file on a virtual drive).
3. Boot menu was initially not detecting external drive, so installed rEFIt - An EFI Boot Menu and Toolkit. Now it is detecting the USB Drive.
Now when I boot from this device, it get a black screen with the message "No bootable device - Insert Boot Disk"
Request someone to please help me install windows as some softwares which I work with are windows based.

So my understanding is that my Boot Camp Assistant (BCA), since it does not allow USB installer, it sets NVRAM to boot from Optical Drive. Right?
Yes.
So can I change it or update it to another BCA version which supports the same??
All BCA versions drive the logic based on the Mac Model Identifier. Unfortunately there is no real workaround. .

Global reset of file / folder permissions on a USB Drive

I just migrated to a new MB Pro. I now have an issue with file permissions on my USB drive that I use for Time Machine and some other external data. I understand (sort of) why the permissions are messed up, because you're forced to come up with a new user name when you migrate your data and applications. That being said, I just want to globally reset / update the permissions on my USB drive and it's data so that I'm the owner; and I can read and write. And I want to save all my data.
I've started this process going from the "get information" screen, so I think I know how. But it's been running forever. Isn't there some type of universal setting for a drive or does it just need to crunch thru every single file and directory?

Whatever you've done already it's the wrong thing to do. You cannot arbitrarily change permissions on every file on your backup using the Get Info window. The result will be a complete screwup of all the file permissions on your backup. You will manage to make a simple problem into an unsolvable one.
Next time you should ask first before you act rather than after when you cannot go back. Since you did this to your TM backup drive about all you can do at this point is erase the drive and start your TM backups from scratch. Of course this doesn't resolve anything for whatever you tried to migrate to your new computer.
If you migrated your old Home folder to the new computer then first be sure the account has admin status, then log into the account. You should then have full access to all your restored files. You can then delete the other user account.

How to stop importing from usb drive going into root ITMS directory

First time I imported, everything was fine. I was trying to get rid of some duplicates and got rid of one of the main subdirectories (I had "Itunes Music" folder with two main subdirectories, let's call them "Laptop" and "Desktop." I noticed I had many duplicate artists from these, so I deleted the "Laptop" directory. Naturally, all these showed up with asterisks on iTunes. With no easy way to delete them all (can't sort based on asterisk, apparently), I removed EVERYTHING from my Library and attempted to copy over from the USB drive again. This time, the contents of "Laptop" went into the root "iTunes Music" folder (so there were now ~50+ folders including the "Desktop."
This isn't working for me, since my objective is to get rid of the duplicate work (duplicate tracks I can somewhat stomach, but I also have some duplicate "Artists" which is driving me crazy). I removed everything from the library, deleting it all (~30+GB) and deleted all of the subdirectories from the iTunes Music folder.
When I went to reimport it all again. I dragged the "Laptop" folder from Finder on the USB drive into the iTunes Music directory again (as I did the first time), recreated the and everything continues to populate the top iTunes music folder. Is there any way to stop this? I want the "Laptop" folder to stay in it's subdirectory structure distinct and separate from the "Desktop" folder so I can ensure I am not unnecessarily increasing my structure.
One easy (though extremely tedious) alternative could be to import the folders one at a time... but I'd really like to avoid that. But for my first mistake, this wouldn't have been an issue. I haven't changed any settings on iTunes, so please advise!

I have duplicate (different) stuff on the laptop versus desktop but some unique to each (and all kinda scrambled up). I first started importing on my old G3 ibook. It was slower and chugged harder and some are at really low bitrate, for example, and also lack album art. My XP desktop was made for gaming and is much more powerful, so I always did high bitrate and was much more careful to do all the album art, etc.
Now I'm trying to consolidate it all on my new MBP... Mostly, though, it's a mess and I've been putting this off for years and it's mostly my fault. My biggest gripe is the large number of duplicate tracks. I can live with these when they're from different albums (compilations mostly), but not when one is a lower bit. I imagine I'm gonna be doing it the hard way, one album/artist at a time...

[SOLVED]Mounting usb drives "not authorized" with thunar-volman (XFCE)

Hi,
I'm new to Arch (even though I must be approximately at my 15th try at installing it properly) and I have a problem with thunar-volman.
Whenever I log in as user, and try to mount a usb drive with thunar, let's say I want to plug a drive labeled Ext3_8Go, I get the same message in a pop-up window : "Failed to mount Ext3_8Go (or anything close, not in English in the text), not authorized (that part is in English)"
My install is :
- net install
- partitions : 9Go for /, no swap, no separate /home
- packages : base and base-devel. The only modifications in the package list is that I remove ppp, pcmciautils, and xfsprogs.
- config : at the install stage I only modify rc.conf to change LOCALE and HOSTNAME, and pacman's mirrorlist to allow all French mirrors in addition to the one at the top.
When the usb installation is over, I run this script :
"installation_xfce.sh" (there may be some errors left, I modify this script as I learn) :
#!/bin/bash
# expected environment : freshly installed archlinux, login : root.
echo "Are you connected to internet ? If not, please Ctrl+C and reload this script when connected"
echo "Otherwise, press ENTER to continue installation"
read var_dummy
echo "Creation of the user : please type in your user name :"
read var_username
useradd -u 1000 -g users -G audio,lp,storage,optical,video,wheel,games,power,network -d /home/$var_username/ -s /bin/bash -m $var_username

I can mount as a user, no password asked, with :
udisks --mount /dev/sdb2
but the GUI method tells me "not authorized".
"groups user" outputs :

For those who don't have time to read the installation script, DBUS is in the DAEMONS list of rc.conf, and .xinitrc launches : exec ck-launch-session startxfce4
Any idea ?

Thanks a lot !
That worked !
I stumbled across this part of the wiki several times before, but didn't really understand so I had not tried.
If anyone's interested in the script, here's the corrected version :
#!/bin/bash
# expected environment : freshly installed archlinux, login : root.
echo "Are you connected to internet ? If not, please Ctrl+C and reload this script when connected"
echo "Otherwise, press ENTER to continue installation"
read var_dummy
echo "Creation of the user : please type in your user name :"
read var_username
useradd -u 1000 -g users -G audio,lp,storage,optical,video,wheel,games,power,network -d /home/$var_username/ -s /bin/bash -m $var_username
echo "You will now be asked to create the password for this user:"

USB Drive and iPod do not show up on desktop

Hello,
I put the computer to sleep when I'm going to be away for awhile and overnight. When I come back and wake it, my USB drive does not appear on the desktop. I have to restart the iMac to get it to come back.
Also, when I plug my iPod in, iTunes updates it and then within 10 minutes, the icon does not show on the desktop but I can see the iPod in iTunes.
Any ideas?
Thanks,
Brad

I did run the hardware test and everything passed.
For about 3 hours last night, everything was working fine. This morning the USB drive icon is there but not the iPod. I think I will try the OS reinstall but not for about a week. I will be out of town all next week and can't get to it before I leave.
Something may have gone wacky while loading some application. A couple of the suspects would be Adobe Lightroom beta 4 or Google Earth. This issue only started within the last 5 days or so and I think those are the only applications I've loaded in that time.
Thanks for the help in eliminating some of the culprits. I think the OS install should fix. If not, it may be time to have Apple take a look.
