My Firefox always changes Network settings to 'Use Manual Proxy' after every PC restart, even if I change the option to No Proxy/Auto detect proxy.

My Firefox 4 always changes the Network settings to '''Manual Proxy Configuration''' after every PC restart. I have to always go to connections and change this setting to '''No Proxy''' or '''Auto Detect Proxy Settings for this network'''.
I also tried to revert the values back to default values by using about:config and changing modified values back to default. But it still doesn't works out.
Kindly help.
Thank you.

I had this too, I tried running Firefox in safe mode (no add ons) - that didn't make any difference. I could save other preferences, just not the proxy setting. I'm 99.99% sure I didn't have a virus or other malware. This was only affecting Firefox, no other browser I has installed.
In the end I created a new profile - http://support.mozilla.com/en-US/kb/Managing%20profiles - that seems to have 'fixed' it for me - the new profile doesn't have the problem, but the old one still does.
Windows 7, Firefox 4.01.
Cheers

I can't read the text on my toolbar after changing personas, and unchecking "use text color" doesn't do anything even if I change personas.

Several personas come with unreadable text and accent color. This article explains how to resolve the issue:
http://support.mozilla.com/en-US/kb/Cannot+read+text+after+selecting+a+Persona
However, when I followed the directions, the text colors did not stay the same as I switched personas.

If you have installed a persona then the default text color and background color of the toolbars are defined by that persona. 
The colors of the currently selected persona are stored as the first entry in the pref lightweightThemes.usedThemes as textcolor and accentcolor.
You can edit that pref and set another value for the "textcolor":"#ffffff" part (e.g. "textcolor":"#000000").

Where can I read the proxy settings Firefox chose, when configured to use "Auto-detect proxy settings for this network"?

I would like to set my system network proxy settings to those, Firefox chose. Firefox is configured to use "Auto-detect proxy settings for this network" and this works fine. How can I read out the settings Firefox chose, so I can adapt these system?

Hello Richard,
Download MozBackup and make a backup of your bookmarks and passwords. Uninstall firefox and remove ALL folders with the name "Firefox".
Install Firefox and restore your bookmarks and passwords. Now you should have a fresh install so you have to make all settings again.

Upon startup Firefox says "Proxy is refusing connections." When I select "Auto-Detect Proxy" from Advanced settings and solve problem, changes are not saved and upon next startup I must select again...!

Firefox 4 was working fine. Then one day, when I started up Firefox, it says "Proxy is refusing connections." I solved this by selecting "Auto-Detect Proxy" from Advanced network settings, but my changes are not saved and upon every start-up I must select it again! (I even completely removed my webroot antivirus protection, as it as hindering many proxy related programs, but this seems to not be the source of the problem)

You can find the connection settings in Tools > Options > Advanced : Network : Connection
If you do not need to use a proxy to connect to internet then select "No Proxy"

Turn off your firewall and antivirus software.

Is there a way to personalize my font in my icloud email i.e. make permanent change/default settings to font, color. I don't want to make these changes on each individual email?

Will an iphone 4 that was originally purchased from apple directly as a factory unlocked phone remain unlocked or will it have now locked to the network it was used on. I've been told by carphone warehouse that the iphone will lock to first sim used in it

Will an iphone 4 that was originally purchased from apple directly as a factory unlocked phone remain unlocked or will it have now locked to the network it was used on. I've been told by carphone warehouse that the iphone will lock to first sim used in it (in this case Orange) and will need to be unlocked again. Just wanted the view of anybody who knows about this for sure. Thanks

If you bought it directly from Apple as unlocked it should be unlocked for all networks. There are phones sold that WILL lock to the first carrier it is used with, but this does not apply to phones where the receipt says "unlocked".
I have not had good experiences with Carphone Warehouse.

Trying to setup a group policy to force auto detect proxy setting on multiple machines on our network

We have the proxy configured on our computers to use a pac file, now we need to remove the pac and set it to auto detect proxy on our network. Do you have a adm file that works with 7.0.1 or another way to push this out on multiple pc's.

You can use a mozilla.cfg file in the Firefox program folder to lock prefs or specify new (default) values.
Place a file local-settings.js in the defaults\pref folder where you also find the file channel-prefs.js to specify using mozilla.cfg.
pref("general.config.filename", "mozilla.cfg");
pref("general.config.obscure_value", 0); // use this to disable the byte-shift
See:
*http://kb.mozillazine.org/Locking_preferences
You can use these functions in mozilla.cfg:
defaultPref(); // set new default value
pref(); // set pref, but allow changes in current session
lockPref(); // lock pref, disallow changes

Lightning is a problem for you because it hooks into Thunderbird at a low level and you need a version compiled for the platform Thunderbird is running on. So you can't do the preferred solution, which is to put your whole profile in a shared folder and have both instances of Thunderbird reference the same profile. (Ditto for Enigmail). Lightning may become an integral part of Thunderbird in an upcoming release, at which point this limitation due to Lightning should disappear.
And if you can't use a shared profile, you can't set your Lightning, or your Address Book, to share a common set of files. Put another way, the linkage from Thunderbird to its address book files and calendar data is hard-coded, and not exposed where we can adjust it. :-(
The halfway house is to place your mail stores in a shared place, and use the Local Directory setting in each account's settings to connect to it. They don't need to be in the profile; what's more important in your case is that they are in a folder accessible to both operating systems.
Look in your profile; everything under Mail and ImapMail needs to be moved out to a shared folder. Note the entries in Thunderbird under Local Directory before you do this, and reconstruct those pathnames in Thunderbird, but adjusted to suit their new locations.
(You can see here that you need to make many adjustments, one per account, in each instance of Thunderbird, so it's a high-maintenance solution and this is why we don't recommend it when the alternative, moving the whole profile, is possible.)
I share address books and calendars between Thunderbirds on various computers (and my phone and tablet) by syncing to something in the cloud; Google Contacts and Google Calendar are my choices, using gContactSync and CalDav.
Having made the break myself some years ago, I'd recommend you break away from Windows. ;-)

How to change Network Settings on iPhone OS 3.1.3 on my iPhone 3G?

I'm using the iPhone 3G locked with Bharti Airtel in India. Airtel, for a brief time was authorized to unlock the iPhone 3G after the completion of contract period of a year but, now it doesn't.
Airtel has three network settings but I'm unable to change the settings. I need to change it to use unlimited data plan. Is there any official way to change it? and if not, will it possible to change the settings after I unofficially unlock it? Please suggest.
P.S. I'm running the latest iPhone OS 3.1.3

The ability to change the APN settings on the iPhone depends on the carrier file. Basically the carrier has told Apple if they want the settings to be enabled or not. In the case of the iPhone in Canada all carriers do not allow for the APN settings to be changed, and it would appear that Airtel is the same.
If the iPhone is being used properly with the carrier that the iPhone is locked to there should be no reason to change the APN settings.

As far as unlocking the iPhone goes the only way it to see if your carrier will unlock it for you. According to Apple you are correct in saying that Airtel does not offer unlocking, but you can always call them to double check.
http://support.apple.com/kb/HT1937
Hacking the iPhone is not recommended, and can not be discussed here on this forum. You can search Google, but if you are running 3.1.3 hacking your iPhone to unlock it might not even be an option.

I accidentally changed network settings and now I can't connect to internet

(I posted this on the board for OS X 10.4, but I figured my OS is irrelevant to my problem, so I thought I'd post it here for a better chance of getting help)
I accidentally changed some network settings on one of the computers on my network, and now it wont connect to the internet. All the other computers on the network work fine. I guess I need help getting things back to how they were.
I have absolutely no experience with networks, so I don't have a clue what to do. One thing I notice that might be of help is that when it's set to "Configure: Using DHCP," the section for "Router:" is blank. No address. The router address on all the other computers is 192.168.1.1. Similarly, the IP address on all the computers is some variation of 192.168.1.x, but on the problem computer it's a completely random number (as far as I can tell).
Any help would be EXTREMELY appreciated.
Thanks!

Open Network preferences on the computer, select the connection method, click on the Advanced button. Click on the TCP/IP tab and set the Configure IPv4 drop down menu to DHCP. Click on the Apply button.
BTW, you need to post your questions in the appropriate forum which would have been the appropriate Tiger forum. This is the Snow Leopard forum.
