Save user modified 'about:config' settings in FF 9

Nifty YouTube vids about increasing speed. Go to 'about:config' and modify pipelining & persistent settings. However; when I restart FF and check, the settings are back to what they were before. So, how can I save the settings?

  • Migrate about:config settings from 3.6 to 4.0

    Over time, I have incorporated many changes and enhancements to Firefox 3.6, in the about:config settings. Many of these are timing changes or speedups of basic settings recommended by users and others intent on making things faster.
    Will it be at all possible to move this over to 4.0, or is that pretty much a "start over" kind of project?

    Put those prefs into a '''user.js''' file, to make them more "portable". That makes it a lot easier when you need to ''(or want to)'' create a new Profile with all your special Firefox about:config change.
    To get started creating a new user.js file you can open your '''prefs.js''' file in a simple text editor program ''(one that won't change the line formatting appearance)'' and copy the prefs that you changed in about:config into another text window line-by-line. <br />''(Yep, you need to find them line-by-line, they're going to be intermixed with prefs set by extension that you have installed.)'' <br />When you have all those prefs in the 2nd window, you can add the code needed by the user.js that differs from what prefs.js uses - '''user_pref(" ''' & ''' ")''' before and after the actual pref - type it once and copy&paste each of those two line-by-line for each pref line.''<br />
    http://kb.mozillazine.org/User.js_file <br />
    It's a lot of work the first time to get started with a user.js file, but it the long run it's a real time and frustration saver. I have been using the same basic user.js file since 2005, and all I need to do is change the few prefs that might get changed in a new version and also add whatever new prefs that I want to set for the new version, for new added features.
    ''Additional information about using a '''user.js''' file in Firefox:'' <br />
    Firefox looks at the user.js file every time it starts for additions or changes to preferences, and then writes those to the prefs.js file.
    '''user.js''' doesn't exist by default, it has to be created. This extension will create that file automatically upon installation and it provides an editing window for the three "user" files from within Firefox. ''You don't have to dig thru your file system every time you want to do a minor edit.''

  • Modify about:config and allow pop ups for multiple systems

    What I need to accomplish:
    security.mixed_content.block_active_content = False
    Allow all pop-ups from salesforce.com
    I need to do this for 70 computers within my domain.
    To modify about:config, I've tried editing user.js (I had to create the user.js file as it did not exist in my profile folder) using the batch file below.
    Batch File to edit user.js
    cd /D "%APPDATA%\Mozilla\Firefox\Profiles\*.default"
    echo user_pref("security.mixed_content.block_active_content", "false");>>user.js
    I've read that the permissions.sqlite file can be edited to allow the pop ups, is there a way for me to edit that from a batch file?
    Are these modifications possible without having to visit each user?

    You can also use a mozilla.cfg file in the Firefox program folder to specify new (default) values for refs.
    *http://mike.kaply.com/2012/03/16/customizing-firefox-autoconfig-files/
    Place a local-settings.js file in the defaults\pref folder where also the channel-prefs.js file is located to specify using mozilla.cfg.
    pref("general.config.filename", "mozilla.cfg");
    These functions can be used in the mozilla.cfg file:
    defaultPref(); // set new default value
    pref(); // set pref, but allow changes in current session
    lockPref(); // lock pref, disallow changes

    I don't know of a way to easily modify the permissions.sqlite file to add an allow pop-up exception.<br />
    You would need an SQLite manager program that accepts command line input to add such a record.<br />
    The main problem would be to get the ID value to be used.
    *INSERT INTO "moz_hosts" VALUES ("<id>","www.salesforce.com","popup","1","0","0","0","0");

  • How do I save changes to about:config?

    I change the keyword url in about:config but don't know how to save this change. If just close the tab or the browser, the old settings reappear.
    How do I save changes to about:config?

    Start Firefox in <u>[[Safe Mode]]</u> to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
    *Don't make any changes on the Safe mode start window.

  • How can I retain about:config settings when updating firefox?

    Really appreciate all the hard work creating updates but every time I update I lose my about:config settings, especially the browser.tab ones that I rely on. Specifically I use non-default settings on InsertRelatedAfterCurrent and all the warning ones. (I never want to be warned). I also use the Tabs on Bottom plugin which also has to be reinstalled after major updates. I run Firefox on at least 4 separate machines so it is a rather huge headache to have to reconfigure after each update. Is there a way to tell Firefox to update but don't change my settings back to defaults?
    Thanks for a great browser.

    Those settings should not get lost...
    Is it possible you used the Refresh feature? Sometimes after an update installs Firefox displays a message that it is running sluggishly and you can improve performance by restoring some default settings. That runs the Refresh feature, which will default your settings and remove all of your extensions (the ones you installed into Firefox yourself, not ones that were added by other software on your system). The telltale sign is that an Old Firefox Data folder appears on your desktop with your "old" settings folder inside. If you have experienced this repeatedly, there may be several old folders inside. Could that be the explanation?
    You might want to create a backup of your prefs.js file, which stores your modified Firefox preferences, before your next update. You can find that file in your currently active Firefox settings (profile) folder as follows (either):
    * "3-bar" menu button > "?" button > Troubleshooting Information
    * (menu bar) Help > Troubleshooting Information
    * type or paste about:support in the address bar and press Enter
    In the first table on the page, click the "Show Folder" button. This should launch a new window listing various files and folders in Windows Explorer.
    Scroll down and make a copy of prefs.js (or it may shows prefs and a file type of JScript) in a safe location such as your documents folder.

  • When closing Firefox windows, I would like a warning before the last window closes. The about:config settings do nothing. There is a warning for multiple tabs..

    When closing Firefox windows, I would like a warning before the last window closes. The about:config settings do nothing. There is a warning for multiple tabs... why not for the last window? I do not use tabs... just windows... I have a mouse button programmed for that. It is really irritating to have to restart Firefox all the time and then open the history window because no warning was issued!

    This is ridiculous. I've had this problems for years now and I'm finally walking away from Firefox. I use my keyboards more than my mouse, and how many times does your finger slip and hit Command Q instead of W. How come FF can't reset something as trivial as this? So many people are having problems with this?
    Feels like FF has become too big, too slow and just not cooperative anymore. What a shame, I've been using Netscape/Firefox for 13 years. This is silly.

  • How could I sync About:Config settings?

    (I'm not very good at English, if you don't understand something of my problem description please tell me).
    I have 2 OS on my PC: Windows 7 and Windows 8 RP (for the time of this question) - I keep Firefox synced between the two with Firefox Sync. Some days ago (at the time of this question) I changed some settings on about:config in 7 and denoted at the next day that these changes were missing on 8. I already know how to move "prefs.js", but I wanted to know if there was any possible way to sync my about:config settings between these 2 and continuosly and keep them synced on the cloud so whenever I make some change it applies for both systems.
    If possibly by Firefox Sync.
    (In other words: Sync "prefs.js" between my 2 OS).

    Only prefs that are white-listed as services.sync.prefs.sync.* prefs with a true value will be synced.

  • How do I set the about:config settings for all users? iprism keeps prompting from authentication for users.

    When users log on and try to open Firefox 23.0.1, users are prompted with Iprism Authentication. We made changes to the firefox about:config values "network.automatic-ntlm-auth.allow.-non-fqdn" and "Network.negotiate-auth.allow-non-fqdn" to true and it works, but only works on a per user basis. How can we set this up for all users?

    I would think the about:config entries discussed are ex-factory set to values each user has to change individually, after the installation has run its course. The solution could be to have patched files ready to install post factum:

  • About:config settings change by themselves when switching between windows/linux on dual-boot machine with profile shared between OSs

    I dual-boot ubuntu and windows7, and have set up firefox to use the same profile data when running under either OS. This works great, except:
    (1) each time I switch OSs and start firefox, it runs the "checking add-on compatibility" test (which is a minor annoyance)
    (2) each time I start firefox in ubuntu after recently using it under windows, the about:config setting "browser.backspace.action" gets reset from my preferred setting (0) to the default setting (2).
    How can I prevent these two things from happening?

    Maybe it is better to use separate profiles for each OS and create symlinks or hard links to the sqlite databases that you want to share.
    Your Linux profile may be using extensions (e.g. Ubuntu Firefox Modifications) that modify specific settings and in such a case you can't really prevent this.<br />
    You can use a user.js file to initialize specific prefs on each start, but that makes it impossible to make changes on the about:config page that last the current session and you need to remember which prefs are affected.

  • Where are the about:config settings for a profile stored?

    I am setting up a custom firefox profile and would like to tweak some of the options that are accessed via about:config.
    I would like to know where this information is stored and whether I am able to modify these options outside of the browser.

    Thanks, I was modifying the prefs.js file the whole time but didn't realize these were the same settings from about:config. The user.js file is also useful to know.

  • My About:Config settings aren't being saved

    So when I type in the URL bar, it shows,
    Firefox can't find the file at jar:file:///C:/Program Files/Mozilla Firefox/omni.jar!/chrome/en-US/locale/browser-region/region.properties(search text)
    so I go to about:config and reset the keyword.url, but each time I close firefox it resets back to the weird jar:file thing. How do I save my settings?

    Start Firefox in <u>[[Safe Mode]]</u> to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
    * Don't make any changes on the Safe mode start window.
    * https://support.mozilla.com/kb/Safe+Mode
    * [[Troubleshooting extensions and themes]]
    If it does work in Safe-mode then disable all extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
    * Use "Disable all add-ons" on the [[Safe mode]] start window to disable all extensions.
    * Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")

  • The proxy settings supplied by my work's IT dept. don't work with Firefox on my Nexus. I have entered them in the about:config settings list but to no avail.

    I have tried to change the config settings in line with a lsited posting, and these are:
    network.proxy.type =1
    network.proxy.http = setting from IT dept.
    network.proxy.http_port = 8080
    Is there anything else I should do?

  • Change about:config settings via mac terminal

    Hello,
    I administer over 140 mac computers, all with firefox installed. Unfortunately it seems like a daily occurance when a user calls and says that firefox is bugging them to update, which they cant because they are not admin accounts.
    Now I use apple remote desktop to turn off auto-update for a lot of other applications like software update, microsoft office, and adobe. Unfortunately since firefox doesnt use a standard plist file on the mac I cant use default to write the preference remotely.
    Question: Is there a way to write to the firefox config via command line so I can turn off auto-update in mass instead of having to touch each computer and make the change in the GUI?
    thanks!

    Use a mozilla.cfg file in the Firefox program folder to lock prefs or specify 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
    lockPref("app.update.enabled", false);

  • In the about:config settings what is the preference "browser.taskbar.lastgroupid" do?

    I recently installed the FF4Beta6 along side my original 3.6.10 and noticed that both versions have this preference with a user set string value of Mozilla.Firefox.4.0b6. In the taskbar I have shortcuts to both versions pinned in Windows 7. The tooltip box that pops up says "Mozilla Firefox" for the shortcut to 3.6.10 and says "Mozilla.Firefox.4.0b6" for the Beta shortcut. So I don't know what that preference was for and I don't remember ever setting it myself.
