Does Firefox reset all the root certificates and root certificate settings whenever an upgrade is installed?

Does Firefox reset all the root certificates and root certificate settings whenever an upgrade is installed?

Root certificates are stored in the file nssckbi.dll and if you've disabled build-in root certificates then it is possible that they get re-enabled. There is however no reason to disable any of the build-in root certificates.

  • Ryanair 'flights' dialog box does not load; all the rest works, and in Opera it works; can you help? it seems everything else works fine

    Ryanair 'flights' dialog box does not load; I tried in other languages too, it is the same error; it works fine with opera browser in this very same computer I am writing in; please help, if you can; it worked up to two months ago, then I don't know, too long has past from last time I used ryanair, and the rest works all fine, it seems... thanks so much for your time,

    Start Firefox in [[Safe Mode]] to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).<br />
    See [[Troubleshooting extensions and themes]] and [[Troubleshooting plugins]]<br />
    <br />
    If it does work in Safe-mode then disable all your extensions and then try to find which is causing it by enabling one at a time until the problem reappears.<br />
    You can use "Disable all add-ons" on the [[Safe mode]] start window to disable all extensions.<br />
    You have to close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")<br />

  • Why does firefox lose all the tabs when logging on? annoying to remember the ones I had open

    I open a few tabs with most used sites, facebook, ebay etc and when i log off i save and exit, some times it keeps them other times they go

    Make sure that you do not use [[Clear Recent History]] to clear the browsing history.
    Session restore works more reliable if you choose Tools > Options > General > Startup: "When Firefox Starts": "Show my windows and tabs from last time" instead of relying on the Save & Quit dialog.

  • MyStart-by Incredibar - How do I get rid of it. I have tried resetting Firefox in all ways ad infinitum, and all the other suggestions I can find. I

    For the past few months I have been trying to get rid of MyStart by Incredibar. I have reset my computer to Firefox default, I have restarted Firefox with and without addons, I have searched with windows explorer and found and removed anything with incredibar and mystart and even file extensions. I am not particularly adept at understanding all the programming that constitutes the set up of my computer but with a step by step guide I can probably clean my machine. Please will someone help me just get rid of it.

    In order to uninstall a possibly unwanted extension, please do the following:
    #From the Firefox window click the Firefox button at the top left and select ''Add-ons'', or, if the Firefox button is not shown, click the ''Tools'' menu and click ''Add-ons''.
    #Once the Add-on Manager has opened in a new tab, click the ''Extensions'' button on the left side of the window.
    #You should now see a list of your installed extensions on the right side together with buttons on the right side of each extension.
    #To remove an extension from Firefox, simply click the ''Remove'' button. You should see a message that informs you about the successful removal of the add-on.
    #Note that some add-ons require a Firefox restart to be removed completely. To perform a Firefox restart after the add-on removal, click the ''Restart now'' link in the message.
    You can find further information about uninstalling extensions in the following articles:
    [[Disable or remove Add-ons]]
    [[Remove a toolbar that has taken over your Firefox search or home page]]

  • I have reset Firefox, followed all the various instructions for ALL the faults and it is STILL not working properly !

    Various problems :
    Firefox crashing, missing toolbar, bookmarks disappeared (reset and now they won't work at all) , cannot set homepage again (despite following all instructions), shockwave flash constantly unresponsive (again, all instructions followed and no change), Firefox especially slow in facebook, sound volume keeps switching itself off.
    I have gone through each problem with all the suggested "fixes" AND reset Firefox, but it is worse now than before !

  • HT4864 problems with iCloud mail server on the mail, but it does not fix it when I put the password in, keeps asking me for password. When I go into iCloud to access it from safari, it accesses the icloud fine with my password. I have reset all the settin

    I am running os x 10.7.5, on a macbk, I have been using all the apps fine and not changed anything or run any software updates, suddenly my mail dows not think it can connect with the outgoing server for icloud and requests my password, which I give, but it repeatedly asks again and again. I have tried re-setting all the mail for icloud up again, and it thinks its ok, except the box keeps flagging up can't access outgoing server. I have checked it all a number of times, and I can access the icloud stuff including mail from http when I log in there. Anyone know why my mac will not accept my icloud password? suddenly I cannot get any icloud mail in or out, but I changed nothing. Why does it do this and why can't i fix it?

    No carrier "automatically" unlocks at end of contract - many won't do it at all, even if requested.  I don't know what your carrier's policy is since you didn't say what country you're in.
    However, if I understand you correctly, you didn't change carriers so it doesn't matter if it was unlocked or not. Try the following steps, as needed:
    1. Reset phone - press both home and sleep/wake buttons for at least 19 seconds until the Apple logo appears
    2. Settings > General > Reset > Reset Network Settings
    3. Restore phone in iTunes using a backup
    4. Replace SIM card (don't care what Telstra says)
    5. Restore phone in iTunes as new, without using a backup
    6. Take phone to Apple.

    I have no clue what you mean by "all the different methods."  Here are my suggestions.
    First, try a system reset.  It cures many ills and it's quick, easy and harmless...
    Hold down the on/off switch and the Home button simultaneously until you see the Apple logo.  Ignore the "Slide to power off" text if it appears.  You will not lose any apps, data, music, movies, settings, etc.
    If the Reset doesn't work, try a Restore.  Note that it's nowhere near as quick as a Reset.  It could take well over an hour!  Connect via cable to the computer that you use for sync.  From iTunes, select the iPad/iPod and then select the Summary tab.  Follow directions for Restore and be sure to say "yes" to the backup.  You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod.  Again, say "yes."
    At the end of the basic Restore, you will be asked if you wish to sync the iPad/iPod.  As before, say "yes."  Note that that sync selection will disappear and the Restore will end if you do not respond within a reasonable time.  If that happens, only the apps that are part of the IOS will appear on your device.  Corrective action is simple -  choose manual "Sync" from the bottom right of iTunes.
    If you're unable to do the Restore, go into Recovery Mode per the instructions here.

  • I  would like to update or upgrarde my iphone from 4.2  to  5.0 or higher how can I do this task  A.  my phone does not have a "update" setting  I was told to reset all the settings to new B. will this earase all my contact, files ,notes emails  ??? C.

    Don't reset anything, just connect it to iTunes. If you don't have iTunes on a computer, then find someone who does, turn off auto sync, then connect your iphone and click 'check for updates'. iTunes will download the update, then update that software to your phone. Before you update though, I'd make a backup, just to be on the safe side.

  • When I add a https link to quicklinks, when I click on it, the (:) after https does not go to the address bar and thus the link is not connected. This is happening for all quicklink bookmarks with https:

    Question
    When I add a https link to quicklinks, when I click on it, the (:) after https does not go to the address bar and thus the link is not connected. This is happening for all quicklink bookmarks with https: Is there a solution?

    Try some basic troubleshooting.
    '''Try Firefox Safe Mode''' to see if the problem goes away. [[Troubleshoot Firefox issues using Safe Mode|Firefox Safe Mode]] is a troubleshooting mode that turns off some settings, disables most add-ons (extensions and themes).
    If Firefox is open, you can restart in Firefox Safe Mode from the Help menu:
    *In Firefox 29.0 and above, click the menu button [[Image:New Fx Menu]], click Help [[Image:Help-29]] and select ''Restart with Add-ons Disabled''.
    *In previous Firefox versions, click on the Firefox button at the top left of the Firefox window and click on ''Help'' (or click on ''Help'' in the Menu bar, if you don't have a Firefox button) then click on ''Restart with Add-ons Disabled''.
    If Firefox is not running, you can start Firefox in Safe Mode as follows:
    * On Windows: Hold the '''Shift''' key when you open the Firefox desktop or Start menu shortcut.
    * On Mac: Hold the '''option''' key while starting Firefox.
    * On Linux: Quit Firefox, go to your Terminal and run ''firefox -safe-mode'' <br>(you may need to specify the Firefox installation path e.g. /usr/lib/firefox)
    When the Firefox Safe Mode window appears, select "Start in Safe Mode".<br>
    [[Image:Safe Mode Fx 15 - Win]]
    '''''If the issue is not present in Firefox Safe Mode''''', your problem is probably caused by an extension, and you need to figure out which one. Please follow the [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]] article to find the cause.
    ''To exit Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.''
    When you figure out what's causing your issues, please let us know. It might help others with the same problem.

  • Why does all the apps - default and the ones I downloaded - shut down by themselves repeatedly?

    For the past few days, every single one of my apps seems to shut down by themselves, as soon as I try to open them. I can try to open them several times in a go but still the same thing. Even restarted my phone a few times and deleted the background app, which usually works...
    Also it doesn't save any of my photos or theres a plain grey 'picture' with 'JPEG' on it. Moreover, on my camera roll, when I tap a photo to enlarge it, none of them focuses, so all them are blurry. I can't seem to send messages either: that said I usually get all my notifications shown on my lock screen, but lately it doesn't show at all.
    Another thing, my phone keeps repeatedly buzzing when there is no notification - or email - shown either on the lock screen and/or home screen.
    Please help! I'm running out of options what to do!

    Your best bet is to back up your device to iCloud or iTunes, then reset your device to Factory Settings (Settings>General>Reset>Reset All Content & Settings, but do not restore it from the backup. Add your apps back onto your phone one at a time (download them from iTunes in the Cloud by tapping on the App Store icon, then on Updates>Purchased>All, then click on one or two apps and download them and see if the problem persists.
    Continue to download apps to see if you start running into the issue again at any point. If you are able to get all the apps downloaded and functioning without any issues, then reset the device back to factory settings, and then restore it from your backup, and see if the issues starts up again.
    If it does start up again, then there is something in your backup that is corrupted, and your best bet at that point is to "rebuild" your device from Factory Settings rather than to keep the backup on your device.

    Go to the website of the manufacturer of your printer and check to see if they have released an updated driver for your particular model.

  • I am trying to authorise my new macbook air and it won't let me. I try to de-authorise all the other computers and it says I can only do this once a year and have to wait until the 7th Feb. It does not give me an option to authorise this computer

    Always remember to 'de-authorize' you computer when selling or sending for service. If sending for repairs you might not get the same mother board or HD back and some how this counts as an authorized computer against your count.

    After updating to 8.1.2 my iPad continues to restart. I tried resetting all the settings and this didn't work. I tried rebooting by holding the start button & power button and it didnt work either. The problem has actually worsened. I can no longer use my iPad.

    You need to restore the iPad.
    Use iTunes to restore your iOS device to factory settings - Apple Support
    If that will not work, you will need to use Recovery Mode to restore.
    If you can't update or restore your iPhone, iPad, or iPod touch - Apple Support
