Platform of Firefox profiles are independent?

I would like to transfer my profile data from Windows 7 to 7 Debian. for some reason any the right Sync feature does not work for me.

So my question is, are cross platform compatible Firefox profiles?

for example. can I just copy my windows profile...
"< Profile folder > %APPDATA%\Mozilla\Firefox\Profiles\.
my profile on linux?...
"< profile folder > ~/.mozilla/firefox/.

Not 100% compatible. Some preferences in the file prefs.js (essentially paths from what I've observed files) and some files added by modules may not be fully compatible.

My advice is to copy the files in the profile folder, one at a time, using as a guide for the files to copy.

    I'm using Linux: LMDE cinnamon Edition - 64-bit
    I use the version of firefox Mozilla Firefox 31.0

    I wish to have two instances of FF running. One with my standard, personal settings and a second instance that ONLY connects to Facebook and stop data leakage between the two. I can do this by opening up Facebook in another browser (for example, Chrome, or Opera).
    I checked the ProfileManager under Firefox and created a second profile called "FB".
    I can run firefox Pei FB and she opens an instance of FF with none of my personal settings available - that's what I was hoping.
    However, if I run a second instance of FF - for example the command-line firefox-p default it loads with the same profile as the first instance I opened, not the new profile such as specified in the command.

    I can't that choose the profile if there is no instance of previous firefox running under my user name. The first instance defines which profile is used for all subsequent executions - no matter what profile I specify on the command line. Even running firefox - ProfileManager start with Prime-specifie profile, Profile Manager.


    If you want to run multiple instances of Firefox, you will need to add a - no - remote parameter to the command.

    For example:

    • Firefox - P-no-remote

    Please see:

  • Firefox profile Manager automatically saves the current settings, addons, bookmarks on a profile?

    Or what I need to manually record?

    The profile that you select in the Profile Manager when Firefox starts is the profile that will keep your personal data. All profiles are independent, so if you switch to another profile, then, you will have access to the data stored in another profile.

  • Unique firefox profile all users and profiles on networks

    I am trying to configure Firefox like standard browser for an entire building, and this framework is to ensure that all firefox profiles are registered readers personal network rather than local machines. I can use the Profile Manager to do this on a user base, but what happens if I want that all users of any machine, using the same firefox profile that points to a specific network drive? (This will ensure users always have their browser settings and no matter where they go, allow us to move outside machines without losing all the browser settings, etc..) The contents of this drive is specific to the user account, but still have the same way.)

    As far as I know, the profiles created in the Profile Manager are specific to each user (domain), which would mean a lot of creating manual profile. Is it possible to ensure that Firefox always uses a specific profile of Firefox or the path? Is it possible to have the control of firefox profiles exist (in a .bat file, for example), so I can create the appropriate injector if necessary? Can I use a command line to set the profile to be used by default, or that can be done from the GUI Profile Manager?

    Finally and this can justify a separate query, but I found that when you use profiles that link to a network drive, trying to open firefox on multiple computers will fail (another instance of firefox is open, close it or restart). I can tell Firefox to force the old instance closed, or I have to firefox.exe - no-remote 'differentProfile' Pei each time?

    We are on Windows 7, moreover, for the sake of references.

    Sort of. I don't always have a perfect method to check the presence of a profile, but as a solution, I'm looking in the drive location of my custom profile for prefs.js Server (IF EXISTS 'path\path\Firefox\prefs.js' (thing do)), and that will at least tell me if I have created something here or not.

  • where the fav icons are stored in the Firefox profile? You can drag and drop on the bookmarks?

    Two related issues to fav icons:

    1 where are the fav icon stored in my Firefox profile?

    2 is it not warned to drag an icon on an element of bookmark on my bookmarks (no icon) bar and it updated the icon? (I have a right-click on the bookmark and I couldn't see any field of fav icon.)

    Thank you

    Favicons are stored in the file places.sqlite and bookmarks.

    No, you cannot drag a Favicon in your bookmarks. If you drag a tab favorite icon, all that would happen is that you would be again to add the bookmark and the favicon may not be kept if it was not the first time that you have saved the first time. Try it and see what happens...

    There is no field for Favicon in the context menu of bookmark. There used to be a couple of extensions available at different times which allowed users to add a favicon to a bookmark, but it's been a while that we have seen this type of extension that was compatible.
    Neither have been updated after a Firefox update beat each at different times, and nobody has updated '3' a final which broke.

  • the PC is restarted, all firefox extensions are removed! # aargh

    Since upgrading to Windows 10... Every time I restart my PC, I lose all of my firefox extensions, plug-ins are OK just the extensions are lost...

    I'm going back to IE11 and permanently remove firefox... < < you have not all such extensions > > is a joke?


    It's frustrating. Some of the programs which run at Windows Startup 'cleaning' can change the settings of your browser. Can you make sure that they do not affect the settings of Firefox files?

    The next time that happens, could you check if there is a problem of a broken modules page or if extensions were actually removed? One of the reasons for the empty page add-on to have a list of extensions would be a corruption of database extensions Firefox. You can force Firefox to rebuild the files as follows:

    Open the settings folder (AKA Firefox profile) current Firefox help

    • button "3-bar" menu > "?" button > troubleshooting information
    • (menu bar) Help > troubleshooting information
    • type or paste everything: in the address bar and press Enter

    In the first table of the page, click on the view file"" button. This should launch a new window that lists the various files and folders in Windows Explorer.

    Leave this window open, switch back to Firefox and output, either:

    • "3-bar" menu button > button "power".
    • (menu bar) File > Exit

    Pause while Firefox finishing its cleanup, then rename these files you will find:

    • compatibility.ini to something like compatibility - old.ini
    • Extensions.ini to something like extensions - old.ini
    • Extensions.JSON to something like extensions - old.json
    • Extensions.SQLite to something like extensions - old.sqlite (may not exist depending on how long you have used this settings folder)

    When you start Firefox back up again, he should study your profile folder and other files to rebuild the list. He will probably ask to approve you some of the extensions. Once things settle down, could you check back the page modules.

    Reappear extensions - or are they really gone?

    Also, you can start your profile folder Firefox containing your backup settings. This article has tips on it: back up and restore the information contained in the profiles of Firefox.

    Is the problem that the Windows task bar is hidden by the Firefox window, or that changes to the taskbar make it impossible to change the windows?

    If the taskbar are hidden by Firefox, it is possible that Firefox is in full screen mode. The F11 key toggles between full screen and normal views.

    Another potential problem is that Firefox sometimes seems to collect data of erroneous screen size of the operating system and that the window of Firefox too large. You can rename the relevant settings file to see if that helps.

    Open the settings folder (AKA Firefox profile) current Firefox help

    • button "3-bar" menu > "?" button > troubleshooting information

  • Manager of Firefox &amp; profile partially load, no screen, no menu.

    I've been using Firefox Beta for several years, and shortly after that which began with Aurora. Both were loaded on my computers and worked well. There are several updates after upgrade to beta version of Firefox, it would not load completely. I don't have screenshots, but see no way to tie up here. The best verbal description I can give is the outline of an area where the program tries to load with only the boxes to close/minimize the visible program in the upper right corner.

    Also, I followed the instructions to load the Profile Manager, but get a similar result. This time the name of the program is displayed in the blue header section, but the box is entirely black, while the Aurora was especially so with a black stripe under the section "header."

    Like Aurora, has worked for several other updates before you have the same problem that Firefox Beta, I think that the problem is not the profile that they share the same profile. After trying to update Aurora yesterday, he and Firefox Beta are unusable. The first thing I did was uninstall these two programs and tried to re - install.

    Thank you

    Yes the Aurora and developing Nightly check-ins usually gets every day so they get an update of each of these days. The beta channel receives usually say six to twelve Beta builds for a version with new build since last so that the version 26.0.

  • Why is there the databases for two Web sites in my appdata roaming default firefox profile folder? _ C:\Users\user\appdata\Roaming\Mozilla\Firefox\Profiles\i4unw84s.default\databases\http_


    Two of these databases of site are 64 KB and io_temp.sqlite files. I want to know how they were created and what information is that are stored there. I know that my boyfriend goes to the website of bovada much, but want to know if he has information of personal connection stored for two of these sites. I know that they are not cookies because I saw the list of cookies and delete the and these files are still there. I really want to know if the only way that the sites Web could be in the folder because he saved intentionally information stored on these sites and if not, then why they are part of a roaming profile?

    Hello, I could not find any documentation on what the data in the profile or an io_temp.sqlitefolder - file would do in firefox (perhaps it was a first version of dom storage or indexeddb).
    If you have questions about the use of these sites by your boyfriend, you should probably talk with him directly about this, instead of finding an answer in this way...

  • Why my firefox settings are not preserved when I update?

    Was just invited to update my Firefox to 23.0 and, as usual, asked if I wanted to "import" whatever it is INTERNET Explorer. I said NO - I don't want these settings in Firefox.

    I expect, however, that the update would bring on my customizations of my previous version of Firefox - but it didn't! No preserved Favorites, my window settings (I HATE TABS!) were gone, my wiped out - privacy settings I have to rebuild my environment to pass one version of FF to another?

    Why do you ask me about IE, but not Firefox? And--now--all of these customizations are lost?

    Yes, it looks like your Firefox profile folder.

    You have a profiles.ini file in C:\Users\me\AppData\Roaming\Mozilla\Firefox\

    If this file is there then you can list its contents?

    Note that Windows can hide the .ini file extension, so you can see only one file of profiles also the profiles folder that stores the profile folder.

  • 15.0.1 Firefox what are the system requirements for Mac?

    Firefox should work fine on Mac OS X 10.6.8


    If he has problems with the update or the permissions then simpler is to download the full version and trash the version currently installed to do a clean install of the new version.

    Your profile data is stored in the Firefox profile folder, so you will not lose your bookmarks and other personal data if you uninstall and (re) install Firefox.

  • I didn't know the stored password for a paricular website and I don't know how to acess where it is stored - somewhere in my firefox profile, wherever it is. So I need some directions, please.

    Facebook has changed recently and I was ordering a temporary password to access it
    Fine. But now I want to change my password. For this I must first key in this 'temporary' password and because that I would not change my bookmark, registering there now can't move until I can see what Firefox stored as my FB password.

    I don't know how to navigate within Firefox where are stored passwords - I believe it's in my Firefox profile, but I don't know where this profile file is stored

    You can watch here:

    • Tools > Options > Security: passwords: "saved passwords" > "show passwords".

    You must locate the profiles.ini file and delete this file or use the Profile Manager to create a new profile.


    This problem may be caused by a problem with the profiles.ini file or with the permissions (owner) of the concerned files.

    You can use one of them to retrieve an existing profile or create a new default profile for Firefox:

    • Remove the profiles.ini file to make Firefox create a new profile (default)
    • Use the Profile Manager to create a new profile
      If you have an existing profile, then click on "Choose a folder" in the Profile Manager and navigate to the location of a profile lost to recover this profile

    You should find the file profiles.ini in this hidden place:

    • Windows: %AppData%\Mozilla\Firefox\
      * C:\Users\ < user > \AppData\Roaming\Mozilla\Firefox\
    • Mac: ~/Library/Application Support/Firefox /.
    • Linux: ~/.mozilla/firefox/

    If the file profiles.ini compensation does not work then also check the location of the cache files.

    • Windows: * C:\Users\ < user > < profile > \AppData\Local\Mozilla\Firefox\Profiles\.
    • Mac: ~/Library/Caches/Firefox/Profiles/
    • Linux:~/.cache/Mozilla/Firefox/

    You can also try to rename/delete the MozillaFirefox folder in the two above mentioned places (main, cache).

  • How can I get a new firefox profile?

    My firefox was working properly before, I made a few bad decisions (I deleted a bunch of stuff, I know now that I shouldn't have deleted) and now when I try to open it, I get a pop up window that says:

    'Missing profile '.

    Cannot load your Firefox profile. It may be the mission or inaccessible. "

    I came to the conclusion that I need a whole new firefox, I'll miss the old favorites, but I don't need them. Please could someone explain how I can create a new firefox profile? I love using firefox and I don't want to use a different browser. I'm on a mac.

    This article describes how to create a new profile: use the Profile Manager to create and delete profiles Firefox.
