Firefox reopens after closing???

After I close Firefox down I often return to my computer to find it back open usually with an ad of some sort for spyware removal, or malware. I have run avg numerous times but it has not detected any viruses. I have also disabled many addons from firefox. One time I closed firefox came back and some super mario bros webpage was playing.

hello warpigdave, please also run a scan with different other tools specialised in adware and browser hijackers, like the [http://www.malwarebytes.org/products/malwarebytes_free free version of malwarebytes] and [http://www.bleepingcomputer.com/download/adwcleaner/ adwcleaner].

Both Firefox & Thunderbird won't reopen after closing. require reboot

When I close Firefox or Thunderbird, they do not reopen later. Dialog box says they are still running, but process won't close in task manager. System requires reboot to get back in

Maybe your security (Anti-virus) software is checking files while Firefox is starting and takes so much time that Firefox can't access them and decides to skip loading those locked files. If that happens with sqlite database files like places.sqlite then bookmarks won't work properly. A second start works because the AV software had already checked the file. So you need to check the rules for Firefox in your security software.
A possible cause is security software (firewall) that blocks or restricts Firefox possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox.

Often when I try to open Firefox again after closing it, a message pops up saying Firefox is already running (it is not!), so I have to restart my computer.

Many times when I try to open my Firefox (3.6.11) after closing it, a message pops up saying "Firefox is already running. You must close the porcess or restart your computer before you can open it." Because it is already closed and I have nothing else to close, I close the message and try again, and the same message pops up again... So I have no choice but to restart my computer.

Mail.app will not reopen after closing app

I am using a MacBook Pro with OS X 10.5.8 and Mail.app 3.6 (936). I have all current updates installed. My problem is that I will be using mail.app (configured as an IMAP account) all day and close the application without any issues, but if I reopen the application without fist restarting the computer Mail hangs and will not relaunch. This issue happens without fail. There are only two resolves that will allow me to relaunch mail.app: restart the computer or relaunch the Finder.
What can I do to resolve this issue?
Thanks,
Thom

Anyone one have any thoughts on this? The inability to relaunch Mail.app after closing (without relaunching the Finder or restarting the computer) happens every time without fail. All other applications work without incident.
Thanks,
Thom

Photoshop CC 2014.1 keeps reopening after closing

I have Photoshop CC 2014.1 running on Mac OS X 10.8.5. I use a Wacom Intuit tablet without a mouse. Whenever I close photoshop within a few seconds it reopens. This continues until shut the mac down. I read that removing it from the Dock solve the issue but it didn't fix the is
Anyone else have this issue or a resolution for this bug

Would suggest you to try the same after disconnecting Wacom and using a mouse instead. Check if it works then. If it does, then it has to be your Wacom drivers. Update it and then check.
Else,
Try resetting the PS CC preferences and check if it's an issue with corrupt preferences : http://forums.adobe.com/thread/375776
Try to open PS CC in Plugin Disabled mode and check the same. For that Press Shift+PS CC icon and hit Yes.
Let me know how it goes.

Safari/firefox crashes after closing tab or application with video

i've only noticed this on the nytimes.com website after playing their video content (youtube works fine). in both firefox and safari: every single time i play a video, if i pause it or stop it and then try to close the tab it is in or the application, i get the pinwheel and no matter how long i wait for it, it does not come back so i force quit. i've tried updating/reinstalling, but nothing seems to work. also episodes/shows via abc.com do not play at all - tried reinstalling/updating those plugins/apps as well. this is happening on both macbook pro and macbook with updated versions of leopard... thoughts?

Before you disable all Norton extensions and toolbars in Firefox please read the following two articles:
1. [https://www-secure.symantec.com/norton-support/jsp/help-solutions.jsp?docid=v19802710_NIS_Retail_2012_en_us&product=home&pvid=f-home&version=1&lg=en&ct=us About Norton Toolbar]
2. [http://community.norton.com/t5/Norton-Internet-Security-Norton/Uninstalling-Norton-Toolbar-and-Norton-Vulnerability-Protection/td-p/664973 Uninstalling Norton Toolbar and Norton Vulnerability Protection]
Limiting your security system in this day and age is risky business. Please consider using another browser as a safer alternative.

Saving tabs? reopen after closing safari...

Is there some addon that I could use to save my open tabs over sessions? With OmniWeb and Safari w/ Saft it's possible to close the app and have all tabs reappear the next time the browser is opened. (Also handy for crashes; Saft has a crash protection which asks to bring up all lost tabs after a crash.)
And yes, I know I can bookmark tabs, but that would generate a new entry everytime I close the browser...

Why can't you just use Saft? File --> Save browser window.

What is your operating system?

I keep getting this message after closing Firefox and attempt to reopen-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.

I have customized my Firefox toolbar. After closing the browser and then reopening it, the toolbar has returned to the way it was before I customized it. How do I get my customization of the toolbar to become permanent?

I have customized my Firefox toolbar several times. After closing the browser and then reopening it, the toolbar has returned to the way it was before I customized it each time. How do I get my customization of the toolbar to become permanent?
It has occurred with Firefox 4.0.1 and 5.0

see http://kb.mozillazine.org/Corrupt_localstore.rdf
Take a picture of your toolbars so you can easily reconstruct them from the default after solving the the problem.
If it happens to you it will probably happen again in the future so you might want to keep some copies of your modified localstore.rdf file so you can delete the bad one and rename one of the replacements in waiting. Saving, copying and renaming must be done with Firefox down, of course.

Why do I have to reboot my computor before firefox loads after it is used then closed then reopened but get nothing until I reboot ?

firefox 5.1 or any version has doe this im using XP which was never an issue until these newer versions so
why do I have to reboot my computor before firefox loads after it is used then closed then reopened but get nothing until I reboot ?

I've been having similar issues although mine seem to happen when I import my own movies into Apple TV. After adding new items to my iTunes library and then switching my entertainment configuration to Apple TV, I get nothing but total blackness and my TV says it has no HDMI signal. Once I unplug and repower the Apple TV, everything works fine.

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 exe continues to run after closing all windows, and consumes massive amounts of cpu

after closing all firefox windows and trying to reopen i get the "firefox is still running but unresponsive" message, and have to go into task manager, processes and end the firefox exe, which is consuming between 96 and 100 cpu.

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.

IMAC Yosemite FIREFOX 33.0.2 still getting blank windows after turning off hardware acceleration, they occur in the background and only seen after closing and r

I noticed when my Firefox is minimized that I can not reopen from the Dock on my MAC. So I stop Firefox and reopen, when doing so I get a mixed number of blank windows. After closing these then Firefox behaves as desired until after a bit it all happens again. I read the Windows fix and hoped hardware acceleration would fix it but it does not.

Hello,
Try disabling graphics hardware acceleration. Since this feature was added to Firefox, it has gradually improved, but there still are a few glitches.
'''[https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode Start Firefox in Safe Mode]''' {web link}
While you are in safe mode;
Type '''about:preferences'''<Enter> in the address bar
Select '''Advanced > General.'''
Look for and turn off '''Use Hardware Acceleration'''.
Poke around safe web sites. Are there any problems?
Then restart.

I use private browsing and passowords not remembered. yet after closing all firefox windows, i can access facebook and hotmail w/o my login info being requested

it used to ask me for them when i re-opened a window after closing all the previous ones!

Are you automatically reopening windows from the previous session via session restore?
*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) on the about:config page to disable saving cookies via session restore.
The browser.sessionstore.privacy_level_deferred pref is used when you do not reopen the previous session automatically via "Show my windows and tabs from last time" and uses the same values
