Firefox is saving my open webpages after closing suddenly

I have been using Firefox for a while, and recently noticed this new feature that is causing problems. Firefox is saving my open webpages after closing suddenly, and then when restarted tries to open the same webpages. Huge problem: If it's a site with a virus it goes right back to that site. Huge problem for me- viruses must love this feature. I just want my regular homepages to open if Firebox closes suddenly. Help.

This can be a problem with the file [http://kb.mozillazine.org/sessionstore.js sessionstore.js] and sessionstore.bak in the [http://kb.mozillazine.org/Profile_folder_-_Firefox Profile Folder]
Delete the files sessionstore.js and sessionstore.bak and any existing files sessionstore-##.js with a number in the left part of the name like sessionstore-1.js .
Session restore works more reliable if you choose Tools > Options > General > Startup: "When Firefox Starts": "Show my windows and tabs from last time"
See http://kb.mozillazine.org/Session_Restore

Firefox profile folder becomes read-only after closing browser

firefox profile folder becomes read-only after closing browser
It is a problem with firefox or is it this to to a virus?
How to fix? How to prevent?

Only a check mark in the Read-only box means that a folder or file is Read-only. 
Windows doesn't check all the files in a folder so instead displays a greenish block to indicate that it is not sure. 
You need to look at the files individually to see if any are read-only. 
Easiest to do that is to make the Attributes visible in "View > Details" mode: Choose Details in Windows Explorer.

I just did an update to 6.0 on Lion. Now when I re-open Safari after closing it by clicking the red button it re-opens to my home page, not all my previous tabs.. prior to the update it would re-open with all my previous tabs, which is what I want.

I just did an update to Lion 10.7.4 with Safari 6.0. Now when I re-open Safari after closing it by clicking the red button, it re-opens to just my home page, not to all my previous tabs as it did before the update. I prefer having my old tabs re-open. How can I fix this?

I've had what I think is the same problem since the most recent software update. I have Lion 10.7.4 and have updated to Safari 6.0. The most noticeable difference is that where previously I had two boxes at the top of the Safari window (one to enter URL addresses, one for Google searches), there is now only one box for both functions. I don't like that as well, but I can live with it. However, since the most recent software update my "back button" only works about 5% of the time. Most of the time it is grayed out. So I usually can't get back to previous pages using the back button. Also, when I've clicked a link that opens a new window (for instance, going through the return process at Amazon, I clicked UPS locator and it opened a new window), where in the past I would have just clicked the red button after I had the information, the UPS locator window would have closed, and I would have been back at Amazon - now if I close the UPS locator window, all Safari windows close. The Safari application doesn't close, but the Amazon window closes, I'm back to an empty screen, and I have to open a new Safari window and reenter everything. I'm using a work-around of clicking on History and selecting the description of the window I want to get back too, but that only works part of the time. In the Amazon example, that's what I did once I had the UPS info, but even though I clicked the correct window description, it took me back to the beginning of the return process & I had to reenter all the info. Of course, that info was easy to reenter, but if I'm in the middle of a complicated process, it's a big problem. I've filed a bug report; I surely hope the Apple engineers are able to fix this. I'm used to using the back button function a lot!

Why does Firefox keep me logged into websites after closing and reopening the browser?

As of today, Firefox has been behaving differently. Namely, when I close Firefox and reopen, I am still logged in to email and other sites. I have all of my privacy settings checked, such as clear history, offline data, form history, etc etc so that they all will be deleted upon closing but this has no effect. Can someone provide insight as to why this is happening and how I can correct it? Before today, after closing and reopening the browser I was required to log in to any sites requiring UN and PW.
I have rechecked all history deletion options to make sure all the appropriate ones were selected. Yesterday, I noticed inbox.com and a program called 24x7 Help were installed on the computer, without my knowledge. I promptly uninstalled them,but I'm not sure if they could somehow be responsible for the odd behavior.

Such a behavior indicates that you keep the cookie(s) that verify that you are logged on to a web server.
Are you using session restore to open those tabs automatically?
* Tools > Options > General > Startup: "When Firefox Starts": "Show my windows and tabs from last time"
You can set the browser.sessionstore.privacy_level pref to 2 (never) or 1 (non-HTTPS, default in Firefox 3 versions) on the about:config page to disable saving cookies via session restore.
You can change the browser.sessionstore.privacy_level_deferred pref that is used when you do not reopen the previous session automatically via "Show my windows and tabs from last time".

Firefox process occasionally continues to run after closing browser in XP Pro 64 and uses 50% CPU

Every once in awhile after closing Firefox 3.6.13 the process continues to run. The way I discover this is my CPU temperature monitor is increasing from 36C to 50C, so I open the Task Manger and see that it is using 50% of the CPU, slowing down the computer. I am running XP Professional 64 bit SP2 with all the latest updates on an Intel E8400 3.0GHz overclocked to 3.6GHz and 4GB dual channel DDR2-1066 at 800MHz. This happens only occasionally, maybe once or twice a month. I just end the task and the temperature of the CPU drops and everything is normal again.

Norton IPS is apparently a known issue being mentioned in the KB articles:
*[[firefox will not start]]
* [[firefox crashes when you open it]]
* I also found an earlier post on the Norton site http://community.norton.com/t5/Norton-Internet-Security-Norton/Norton-IPS-1-0-Addon-for-FireFox/m-p/25425#M8494 but I am not sure this is still considered a problem.
What exactly is this IPS extension. I am currently using XPs with Norton's NIS (version 18.6 - it is a paid for subscription). I do have Intrusion Prevention active in NIS but I see no specific extension or program IPS. Is this some optional additional software?
I did find an explanation but from 2009
* http://community.norton.com/t5/Norton-Protection-Blog/Intrusion-Prevention-System-IPS-Your-first-line-of-defense/ba-p/124400
I am NOT using the Norton Toolbar etc. is it these components that are causing the problem i.e safe search etc.
I am not having problems with firefox hanging or continuing, despite using NIS.
There is a bug on this https://bugzilla.mozilla.org/show_bug.cgi?id=548945 but that does not seem to have got very far in confirming or resolving the issue. I imagine Norton have a very large userbase and it seems unlikely that the basic NIS is itself incompatible with Firefox.

Why does Firefox start when I open Dreamweaver after I unstalled Firefox

I uninstalled Firefox, yet when I open Dreamweaver Firefox loads immediately. Why?
== This happened ==
Every time Firefox opened
== After installing Firefox ==
== User Agent ==
Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10_6_3; en-us) AppleWebKit/533.16 (KHTML, like Gecko) Version/5.0 Safari/533.16

I completely uninstalled the printer and drivers and restarted the computer. I then uninstalled and then reinstalled Firefox 7.0.1, restarted the computer and then reinstalled the printer (from the previously downloaded exe file, because I don't have the CD for the printer). Unfortunately, neither of those things worked, but I did notice that when I uninstalled Firefox, it asked if I wanted to save settings, and I said yes and it seemed to remember the Dell 720 printer in the "about:config" menu. So, maybe uninstalling Firefox without saving settings would make a difference. What do you think? Also, I just noticed in the "Add or Remove Programs" menu in control panel that the icon next to "Dell Photo Printer 720" is a little recycle bin, which seems a bit odd. On the dell.com forum, someone suggested using Firefox 5.0.1, available at a different website. Is this worth a shot or are there other more conservative troubleshooting suggestions to try first?

Hi!
Yes it will be there but the status will be changed to closed. If you want to remove the draft, then you should do it by manual

Firefox crashes when I load the start page while it is open. Or when I open it after closing a session.

Sounds like a problem with the current snippet that has a video on it.
Ff there are problems with a snippet then you can set the browser.aboutHomeSnippets.updateUrl pref to an empty string on the about:config page.
Delete the storage\persistent\moz-safe-about+home folder in the Firefox profile folder with Firefox closed ("3-bar" Firefox menu button > Exit/Quit) to remove snippets stored in IndexedDB and make Firefox use a default snippet set.
You can reset the browser.aboutHomeSnippets.updateUrl pref via the right-click context menu to the default value to re-enable the snippets and make Firefox recreate the moz-safe-about+home folder.
Close and restart Firefox after changing the value of the browser.aboutHomeSnippets.updateUrl pref.
You can open the about:config page via the location/address bar.
You can accept the warning and click "I'll be careful" to continue.

You can use this button to go to the currently used Firefox profile folder:

After Upgrading to FF 7, FF does not close properly. I Receive the error "Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system" after closing FF and Re-Opening

in order to open FF a second time i need to manually close the process. i have disabled all plugings

Hi Pelle,
Why did you delete your profile? Also how? Did you use the profile manager or did you delete from the windows file structure?
It sounds like something during the profile delete has stopped Firefox from starting up. Please see the this article and follow the steps:

Firefox freezes when I open it after less than a minute of searching. It freezes regardless of the website I'm on. I've tried reinstalling it several times and have even tried a clean reinstall but it didn't work.

When I open it, Firefox freezes after less than a minute of use. After waiting a few minutes, it unfreezes but then freezes again a few seconds later. This happens regardless of the website I'm on. I've tried uninstalling and reinstalling it and the problem didn't go away. I've even tried a clean reinstallation but it didn't work. This only happens on Firefox. IE and Safari work fine.

-Plug your MacBook into a power source.
-Click on the Apple menu and select "System Preferences".
-Click on the "Energy Saver" icon.
-Click on the "Options" tab.
-Uncheck the box labeled "Automatically reduce brightness of display before display sleep"
-At the top, next to "Settings for:", select "Battery" from the drop down menu.

Firefox keeps running in the backround after closing it, it just lingers there, and when I try to restart firefox, it says that I have to close the current one or restart my system to clear the last firefox. what can I do, thanks...

After the last update, my IBM Clone computer does not close the session of firefox when clicking on "close" it clears the screen back to the desktop but firefox continues to hang there in the backround and will not allow another session of firefox to start until the first session is closed. The only way to reconnect is to do a restart on my system, and then the old firefox session is closed and the new session will start.

Must be the "hang at exit" problem.

Why is firefox not saving previously stored passwords after upgrade to 33.0, all proper settings to have this happen are selected and were in previous version.

After I upgraded to FF 33.0, none of my previous website usernames or passwords were saved when I browsed them. None! I have looked at FAQ responses and carefully looked at my 'Privacy' settings and they are all set to have FF save user names and/or passwords. My cookie settings are 'remember browsing...history' - 'remember search...history' - 'Accept cookies...' 'Accept third-party cookies / Never - and 'Keep until I close FF'
Do I need to select 'Keep until: they expire' for cookies?
Tom F.

hello tom, can you try to remove the remember passwords addon (this is now longer needed, since firefox is now ignoring the autocomplete=off parameter in password fields by default), restart the browser and see if this is making any difference?

Black window remains open even after closing the window programatically

I have an application which has multiple windows. From mainwindow button click event I am closing the child form of the application. The child window is opened after a successful socket, serial or gateway connection attempt, after which the application
do work with some threads and while clicking on a button on mainwindow I am closing this child window after disconnecting the respective connection mode. But after the close event the child window background gets black and it remains open unless and until
I just do a minimize and maximize the application. Please help me on this to get this issue fixed.

Well the details are rather going to depend on what it's doing.
It's a very open ended question really.
But...
Your options include.
Background worker.
https://msdn.microsoft.com/en-us/library/cc221403(v=vs.95).aspx
DIspatcherTimer
https://msdn.microsoft.com/en-us/library/system.windows.threading.dispatchertimer(v=vs.110).aspx
Async Await
https://msdn.microsoft.com/en-us/library/hh191443.aspx
Tasks
Task.Factory.StartNew(() => { Dosomething(); });
Or just a plain thread
using System.Threading;
new Thread(() =>
Thread.CurrentThread.IsBackground = true;
// DoSomething();
}).Start();
Where DoSomething is a method.
You can also have inline code of course instead of a method.
Whilst on a different thread to the UI you can't update UI objects.
You'll get a thread affinity error message if you try.
That means you either return your results to the ui thread and process them there ( particularly convenient with async await ).
Or you update something which doesn't have thread affinity.
An observablecollection bound to an itemssource doesn't have thread affinity eg.
You do need to raise property changed at the end of your processing with that option because it notifies collectionchanged on the wrong thread and the UI won't know it changed.
Or you can dispathcher.begininvoke to get back to the UI thread.
All depends what you're doing but hopefully one of those options there will suit you.
Hope that helps.

Gmail stays open even after closing ff in private browsing

Gmail sign in is home page, I log in each time ("Remember Password" NEVER set for anything) then close browser (do not log out). When I reopen browser gmail is still open, not at the sign in home page as it should be. Before the latest upgrade to FF, all worked correctly, even it I didn't log out, it would reopen to my sign in page.
FF set to automatically start in private browsing. Clear history settings all checked. Remember Passwords not checked. I have also tried setting History to never member anything, accept cookies from sites including 3rd part cookies until I close FF, and clear history (with all boxes checked in Settings) when I close FF-still opens to my email, not to the my mail sign in page.
Any clues?

naah, looks like its problem of firefox, i removed the plugin and tried downloading using the normal download winodw of firefox but same problem, this time it starts picking up item from the download window and continues to download
