  OK, if %AppData% does not lead you in the right place you can also manually navigate to the folder with incident reports (you may need to turn on the display of the first hidden files). It is located in C:\Users\ < your user name > \AppData\Roaming\Mozilla\Firefox\Crash Reports\submitted...

• Firefox hangs very often after the upgrade to 36 on Mac OS

  I have Mac OS X 10.6.8. I've recently updated to Firefox 36.0.1. Since the update Firefox crashes on most news and other sites I frequent.

  Everything that can be done to solve this problem?

  Hello, thanks for the carillon.

  Yesterday I upgraded to Flash to the latest version, and today, I still had the problem, so that is definitely ruled out as a cause.

  OTOH I use FF for 2 days without a hitch I was looking all around), and had the slowdown appear today after I had activated Firebug to monitor the http traffic on a site I'm developing.

  This confirms the impression that I had already obtained Friday that Firebug may be involved. I put a comment their tracker, number #7771

• Firefox crashes very often

  I have been using another browser (Opera) for a while now and recently switched back to firefox. However, firefox always crashes (I count more than 30 accidents over a period of 4 days). (As far as I know), it cannot be traced to any specific web page or activity, it happens even when no activity is carried out to be it (no click, scroll etc.).

  Hmm, this solution has solved a question similar just now

  Does still crash in Mode safe?
  
  You can start Firefox in Mode safe below:

  • Windows/Mac: choose Help > restart with disabled modules
  • Linux: run firefox-safe-mode in the Terminal/Konsole

  If it isn't, then set javascript.options.baselinejit to false in: config:

  • Go to Subject: config in your address bar
  • Press the "I'll be careful, I promise!" button to continue
  • You can search for javascript.options.baselinejit and set it to false by the pref to right click and selecting toggle.
  • Restart Firefox and see if it works properly.

• Firefox blocks despite the creation of the new profile

  Firefox crashes several times all the hours I'm working / browsing. Tried to look at other solutions already posted, including updating / disabling add-ons, reinstall firefox and creating a new session, followed by a new profile.
  Seems to happen more frequently with google sites - withdrew as my homepage, but when you play pandora, he'll certainly down, as well as when using google maps. There seems to be random times on other sites where it will crash as well.
  I have submitted a number of reports of incidents, but it does not give me the opportunity every time - will often simply close without giving me the dialogue of the accident.
  Help!
  Thank you!

• I created a new profile and copied the files from my old computer inside firefox. How do the new profile, just delete the old one?

  I am running windows 7, I had to recover my files on an external hard drive when my old computer crashed. I created a new profile as described in the Web site of firefox and copied all the files into it. I just need to know how to use the new profile when I open firefox, just delete the old profile? Or do I have to reinstall firefox.

  If you no longer have need or intention to use this older profile, then you can use the Profile Manager to delete this profile and delete the files.

• problems after upgrading firefox. reset this is ugly. created the new profile, but can not recover data from old profile.

  I use firefox on a MacBook pro. Mac OS X version 10.7.5. There was an update of firefox on a day or 2 ago. Since this was done, I was getting 'syntax error' 5 times, each time that a page has been loaded. Some research has suggested that an application or a plug-in called "social fixer" might be the problem but I could not understand how to get rid of it so decided to try to reset Firefox. Minutes passed and a message was on the screen saying the old files of firefox have been been "cleaned" or something, but it seems to be 'stuck' because the progress bar was little jerky. Doesn't it usually doesn't. So I clicked on "Cancel". After that, I couldn't even firefox to start. Looks like my profile is unavailable or inaccessible. Following the instructions found on the support site, I created a new profile and I thought I copied the files from the previous firefox on the new profile, but when I run firefox, it's a blank slate. None of my bookmarks or passwords are there. It must be here somewhere, but I can't seem to understand.

  Looks like there was a problem with updating the profiles.ini file.

  • http://KB.mozillazine.org/profiles.ini_file

  You can try to remove the current profiles.ini file to force Firefox to create a new default profile where Firefox has not done that.
  You can check if there is a profile folder with a number of attached time stamp and in this case, you can set the location of a profile created in this folder.

• Firefox crashes after I open a new tab

  Hello

  What could be wrong?
  Thank you.

  You might try using a new profile. It might be hard to go at least a whole day without your pets addons, bookmarks, and history... the bookmarks are fairly easy to copy.

  Create a new Firefox profile

  This is in addition and does not replace your existing settings.

  A new profile will be your plugins installed by system (for example, Flash) and extensions (e.g., security suite toolbars), but no themes, other extensions or other customizations. It should also come with fresh data bases of completely fresh settings and a cache folder.

  Out of Firefox and start in the profile using Start Manager > Search box (or run) - type or paste the following and press ENTER:

  firefox.exe -P
  

  Do not delete anything here.

  Any time want to switch profiles, exit Firefox and return to this dialog box.

  Click on the button to create a profile, assign a name like April8 and ignore the possibility of changing the location of the folder. Then launch Firefox in the new profile that you have created.

  It might take some time to determine if the new profile works better than the old. If you want to import your Favorites from your regular profile in the meantime, here's how:

  You can use the dialog library (Ctrl + Shift + b or "Show all bookmarks") to access the restore feature. The trick is to know where to find your bookmark backups in your regular profile. After clicking on file... you can paste this into the space of file name and press ENTER to drill down to your profile folders:

  %APPDATA%\Mozilla\Firefox\Profiles
  

  The semi-randomly-named folder that has your last backup is generally the one that ends with "failure". Click in that one, and then in the folder bookmarkbackups . Here you can choose the most recently updated to restore file.

  Important: restoring a backup bookmark clears all bookmarks currently in your current Firefox profile and replaces it with the contents of the backup file.

  In my view, it is also reasonable to install AdBlock Plus, Restorer of classic theme, and Status4Evar, like those who, by themselves, are not likely to be at the origin of this apparently rare problem. But I wouldn't add all your extensions to the time in the new profile, and if many show extensions system installed, you can disable those you don't actually use.

• I copied the old file of passwords in the new profile, but do not see.

  Got a new laptop. Copied the content from the old profile to new profile. Most of the old information are there (bookmarks), but I do not see the passwords. I repeated copying the two files key3db and logins.json specifically, but even the passwords saved on my old profile are not there...

  Could you try again in a new profile and copy only the files logins.json and key3db?

  Create a new profile as a test to see if your profile is the source of the problem.

  See "create a profile":

  • https://support.Mozilla.org/KB/Profile-Manager-create-and-remove-Firefox-profiles
  • http://KB.mozillazine.org/Standard_diagnostic_-_Firefox#Profile_issues

  If the new profile works then you can transfer files from a profile already used in the new profile, but be careful not to copy files corrupted to avoid transporting more problems.

• Thunderbird does not work properly after copying old content profile in the new profile, what can I do

  My old laptop crashed, but fortunately I got the hard drive out, who now works as an external drive. I installed TB on my new laptop computer. I copied the contents of the old file to profile in the new profile file and start of TB. I have all my files of pace, but TB does nog works correctly. After that connection, it takes forever to load the new messages, when I leave a message to another, the first answer I get is "TB not responding' and after a few minutes, I finally get to the next message. Same story with 'reply' or 'delete '. I already tried to delete the index file and have tuberculosis still indexing message folders, but this did not help.

  I noticed that my old profile files seems to have a sort of double files in the subfolder Mail, old accounts. For example: pop.tele2.nl, pop.tele2 - 1.nl, pop.tele2 - 2.nl. I'm not sure what they are (they seem to hold different versions?) or is it relevant?

  When I search the AppData/Roaming/profiles I'll find it (on the old and the new hard disk as well) but I can not navigate on him (some parents of hidden file)? I checked the rights on the files of my account profile (Administrator rights). I don't know what to do more, so I hope to help.

  Re: for example: pop.tele2.nl, pop.tele2 - 1.nl, pop.tele2 - 2.nl.
  Here's the e-mail accounts for pop e-mail account. If you have several addresses on the same server, it will have the same name but an additional example:-1 appended to the name. If you got an e-mail account, it can also create and add the additional number. Why you have several, I can't say with certainty what caused them without knowing what you have done. The point being, you must have the directory Local pointing to one that is correct and has all your existing emails.

  Profile files are hidden files.

  What local directory is set to the e-mail account?
  "Tools" > "Account settings" > "Server settings" for the e-mail account
  bottom right under "Local Directory"
  It will say something like this:
  C:\Users\User account name\AppData\Roaming\Thunderbird\Profiles\abc12345.default\Mail\pop.tele2.nl

  Copy paste the info on this issue, so I don't know which e-mail account you use.

  How many email accounts you listed in the left pane in the account settings? You have just the one pop email account and local folders?

  What antivirus do you use?
  If you McAfee please read;

  How many emails you have in the Inbox folder?
  It is advisable to use the Inbox folder as a mailbox for incoming mail, and not as a general storage. Suggest you create folders and move all the emails in the Inbox in other appropriate folders, then right-click on Inbox and select "Compact".

  Good info explaining what is compaction and why it is important:

  • https://support.Mozilla.org/en-us/KB/compacting-folders?ESAB=a & s = Compacting & r = 0 & As = s

  It is also a good idea to Archive mail older than a few months.
  Implemented for archive by month and keep the structure of archive folders. These emails will still be visible by 'Archives' folder and in your profile, but check-in will reduce the size of files and therefore less memory use during their opening.

• Firefox crashes when you open a new window

  Firefox normally opens and runs until I properly - close all windows. When zero windows are present, and I go back to Firefox and ask for a new window, Firefox crashes. To solve the problem I have to force quit the application, which generates an Apple crash report. Occasionally Firefox has crashed on its own and generated a Mozilla crash report, but this is rare. I tried to disable all add-ons, but that has no effect.

  As long as there is at least one Firefox window opens, the functions of the application normally. This problem only occurs when going from zero windows to stop.

  After checking each Add on, beef Taco has been identified as the cause of the problem.

• I need to move some messages (and nothing else) from an old profile of TB in the new profile. How?

  Windows 8.1

  New installation of Thunderbird on the new computer. I thought I had migrated correctly the user profile of the old computer, but when I opened TB, the old profile was not in place and 51 messages downloaded in the new default profile.

  I copied this profile regarding migration and set it aside. I have now the old computer profile up, and I need to integrate the messages downloaded in the meantime.

  What to do, what to do?

  Thank you.

  Install this add-on.
  https://addons.Mozilla.org/en-us/Thunderbird/addon/ImportExportTools/

  Then import the messages downloaded from the mail file in the new profile.
