How to disable addons without starting Firefox

How can I disable addons without launching Firefox.

Note that there is a pref (extensions.enabledAddons) that identifies enabled extensions, so in theory, you can change this pref in the prefs.js file and remove the extensions you want enabled.

If you launch Firefox in Mode safe then all extensions are disabled and you can open Firefox tools > Modules > page Extensions (topic: addons) to disable the specific extension and close and restart Firefox.

You can use one of them to start Firefox in Safe Mode:

  • On Windows, hold down the SHIFT key while starting Firefox with a double click on the shortcut to the desktop Firefox
  • On Mac, hold the Options key when starting Firefox
  • Help > restart with disabled modules

  • How to disable if Windows starts only in safe mode?

    Unfortunately, my Windows 7 has become unstable again.

    Windows starts in safe mode.

    I would like to reinstall Windows, but... of course, Acrobat will not deactivate this mode.

    So, I would like to know how to disable Acrobat Reader in safe mode.

    Help, please...

    Acrobat allows a few activations due scenarios just like that.  In the case that, after you reinstalled Windows, Acrobat you indicates that you have too many activations, you can contact our support team, and they can work with you to get the matter sorted.

  • How to disable Kaspersky modules in Firefox 39?

    I installed Kaspersky Internet Security today and discover that it has installed the 3 modules, I can not turn off:
    -Blocker dangerous websits
    -Money safe
    -Virtual keyboard
    I think I even said 'No' when I started FF and asked if I wanted to install.
    The only option for them is to 'Disable' - there is no 'option' or 'Remove' buttons as like other add-ons have.
    But if I have 'disable', turning it back on, they are enabled again.
    Thanks for any advice.

    Got the answer!
    Will the application Kaspersky and go:

    Settings > Protection > Web anti-virus

    Click on it, then go to advanced settings and uncheck the "Automatically activate the plugin" (and some other stuff to make sure)

  • How can I find a list of the modules of isntalled without launching firefox?

    Short version:
    Is there a way to retieving the list of modules installed by looking at just the files in the profile folder, without starting firefox?

    Long version:
    OK, I did a very stupid thing: I installed Waterfox, decided I didn't need and when I uninstalled it I check 'delete all settings '. I didn't know that he shared all the parameters with Firefox.

    The (...) funny thing is that Firefox was working at the time, and he trotted without complaining for 4 days... today I closed it, open it again and... everything was gone!

    I could "undelete" the old profile folder, recover most of the files in there. Their use, I managed to restore my browsing session... the most important thing.

    Now, I would like to re - install all the Add-ons I used. However, many of them were installed a long time ago, and often they were selected from others with similar names after trying all the. So, it will save me a lot of time and effort so I can retrieve the list modules installed in the folder of "recovered"... profile an idea? For the record, I tried to copy just the old profile folder to the new, but I run into a lot of problems... so, restarted from scratch and just restore the session and now I was wondering how I can get the list of modules of the old profile, to be able to reinstall...

    Thank you

    Giacomo

    It is a bit tedious, but if you search for the GUID, you can probably get the names of most of these extensions because when people stick their list here in the forum (usually behind the link system more next to their post Details), both are included.

  • Security issue on Z480: how to disable the F12 boot in Z480?

    I am owner of Z480 here. In the BIOS, I put in HD as first boot. I also set the password for the BIOS. But I discovered that I can press F12 when the laptop starts to enter the boot menu and I can choose to boot from DVD or other medium.

    So how to disable F12 key start in Z480?

    Hi all

    I found a way to disable the "F12 Boot Menu": in the BIOS, check the "Password on Boot" option and the BIOS admin password. So, even when I pressed F12 at startup, the laptop computer invite you admin password to continue to the Boot Menu.

    This could give a little annoyance that I have to enter the password twice (password BIOS and OS). But it's the price of having better security.

    If anyone has a better idea or found a weakness in the way above, please let me know.
