I have Firefox for U3 and lately it keeps trying to instal an update, which fails and a 2nd window tells me another copy of F'fox is running (which isn't) and when I close the window F'fox starts anyway, but all this takes a lot of time.

I have Firefox for U3 on my Verbatim stick to run on whatever computer I happen to be using. Lately every time I try to open F'fox a window comes up saying "Firefox is installing your updates and will start in a few moments." The status bar indicates the update is progressing, 'though a bit slowly, then suddenly it's done and the window disappears, only to be followed by another window coming up which says "The update could not be installed. Please make sure there are no other copies of Firefox running on you computer and then re-start Firefox to try again."
If I press the 'OK' button OR press the Close button, the window disappears, but then F'fox starts up all by itself anyway.
How can I stop this updating problem happening every time and on every computer I use.

Try to disable hardware acceleration.
*Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"
If disabling hardware acceleration works then check if there is an update available for your graphics display driver.
Try to toggle some Boolean gfx.font_rendering prefs on the about:config page to disable some features.
Filter: gfx
Some to try:
* set gfx.direct2d.disabled to true to disable Direct2D
* set gfx.font_rendering.directwrite.use_gdi_table_loading to false.
To open the about:config page, type about:config in the location (address) bar and press the "Enter" key, just like you type the url of a website to open a website. 
If you see a warning then you can confirm that you want to access that page. 
*Use the Filter bar at to top of the about:config page to locate a preference more easily.
*Preferences that have been modified show as bold (user set).
*Preferences can be reset to the default or changed via the right-click context menu.

I have my FireFox browser set to delete the history when I close the window. It was working for a while and has recently just stopped with no changes to the settings.

I have my FireFox browser set to delete all the history when I close the window. It was working for a very long time and has recently stopped with no changes to the settings. This has happened once before and I deleted FireFox and re-downloaded it, that solved the problem for a short period of time but the issue has come up again. How can I fix this?

Can you check your configuration again? Maybe something went pear-shaped somewhere. It's located in Tools | Options | Privacy and then click the Settings button (see screenshot).

Firefox will close when i close the window but the process doesn't shutdown ever since i had updated to FF25

I am running Win. 8.1 and had no issues with FF 24. Since upgrading to FF 25, firefox will appear closed when i close the window but the process doesn't shutdown. I have to go into Task Manager to end the process. I can then launch it again.

SOLUTION (possible).
Hi all. I had this problem as well. I currently run FF26. A week or so ago, out of nowhere FF wouldn't exit - the window would close but firefox.exe process would keep running in the background using about 50% of CPU. Not sure if it's connected, but just prior to that I clicked on a link on Facebook that looked like spam website, nothing happened, site loaded (sort of, all I saw was a msg - Please Wait...) but nothing happened, I have Eset antivirus and it monitors network traffic and files for viruses, so maybe it prevented my PC getting infected...
So, I had this problem for a few days, was searching the net for solutions, but nothing seem to help. Then, just out of luck I did something that WORKED!
Here's what I did. I noticed that svchost.exe was using a lot of CPU alongside with FF. I ran ProcessExplorer to see what might be connected to this process, the list was long and I didn't have any idea where to start, so what I did was - Right click on svchost process, choose Debug and dismiss the warning. In a few seconds svchost process quit and after that FF started closing properly.
I had to re-enable all my plugins and themes I disabled prior, I also lost my history and preferences which I trashed in the process of searching for solution. But heck, it worked, hopefully for good. Now if someone could point out the real cause of this and fix it for everyone - that would be great. Cheers!

Flash quits when you close the window

Why does Flash CS5 quit when you close the window you were working in? It has to restart every time you close and open a file.

This doesn't seem to be a crashing issue. The program seems to be designed like Windows, wherein the application quits when you close the last open window. This is incredibly annoying and completely unacceptable.

Firefox 6.02 will not save my privacy settings (Use Custom Settings) when I close the window

I am trying to set up my preferences in Google and it tells me that my cookies are not enabled. I open the Firefox 6 Preferences / Privacy window and select the Custom Settings option, to enable third party cookies. When I close the screen the setting is not saved. I am using Firefox 6.02 with Ubuntu 10.04 LTS.

I took the check mark out of the "Remember Download History" box and closed the screen. It saved the privacy settings.

Why does firefox "close" when I close the window but the process doesn't shutdown even with the upgrades since problem was reported.since i had updated to FF25

Frequently after I have been viewing numerous sites on firefox, when I close down the last window and try to reopen firefox, I am told that the program is already running and needs to be shut down. Using Task Manager is not useful, since task manager doesn't show the program as up and running. The only way to get the program to close so it can be used for a different subject is to reboot the computer. This is happening 10 - 12 times a week now, and gradually getting worse. This closes out everything I have open, making it necessary to save all opened files BEFORE I reboot, and then going back to reopen all of them. None of the other questions I've seem point to this particular quirk in the problem.

This is not a cure but will make it easier if Firefox locks up.
'''https://support.mozilla.org/questions/997866''' {web link}
From what I have been reading from other posts on this forum, the
issue may be caused by the clear history settings. It was suppose
to have been fixed in v30.
Press the '''Alt''' or '''F10''' key to bring up the tool bar.
Followed by;
Windows; '''Tools > Options'''
Linux; '''Edit > Preferences'''
Mac; ''application name'' '''> Preferences'''
Then '''Privacy'''.
The button next to '''History''', select '''Use Custom Settings'''.
At the bottom of the page, turn on '''Clear History When Firefox Closes.'''
At the far right, press the '''Settings''' button. Turn on ONLY '''Cache''' and
'''Form And Search History''' leaving the others off.

Even though I set "Use custom settings for history" when I close the window and recheck it has set itself back to "Rember History"..why?

I am having trouble getting the settings to stay and can't figure out why...no matter what I do it just resets every time back to the
"Remember History" and it won't save passwords on some of my sites.

Firefox shows the "(Never) Remember history" choice if all the history and cookie setting are the default. 
Make at least one change to the default setting if you want "Use custom settings for history" to stay selected. 
Otherwise Firefox will revert to "(Never) Remember history" if you return to the Privacy tab. 
The choice "Use custom settings for history" will stay selected as long as not all settings are the default to make you aware that you made changes. 
* Make sure that you not run Firefox in (permanent) [[Private Browsing]] mode
* You enter Private Browsing mode if you select: Tools > Options > Privacy > History: Firefox will: "Never Remember History"
* Uncheck: [ ] "Automatically start Firefox in a private browsing session"
* Websites remembering you and automatically log you in is stored in a cookie.
* You need an allow cookie exception (Tools > Options > Privacy > Cookies: Exceptions) to keep that cookie, especially for secure websites and if you let cookies expire when Firefox closes
* Make sure that you do not use [[Clear Recent History]] to clear the "Cookies" and the "Site Preferences"
Clearing "Site Preferences" clears all cookies, images, pop-up windows, software installation, and password exceptions.

Pop up screen needed when i close the window

Hey ...I got a better script ...
<BODY onbeforeunload="HandleOnClose()">
Then, add the following JavaScript code into the <HEAD> section of your ASPX page:
<script language="javascript">

</script>
But do read about this from the following link

I downloaded an upgrade but when I try to put it in the applications, it says the file is locked. when I unlock it, it still doesn't let me drag it, and reverts back to being locked when I close the window. I am using Mac Lion.

I opened Firefox this morning and it told me I needed to download a newer version. I downloaded the new version. I got the image prompting me to drag Firefox to the applications folder. When I do that, it asks if I want to replace the old Firefox, I click 'yes' and enter my password. It tells me the file is locked. I open 'get info', unlock the file and enter my password. It claims I have read and write access privileges. I then try again to drag Firefox to the applications folder - it says the same thing about the file being locked. I check again under 'get info', and Firefox has reverted to being locked again. I unlock it again and without closing that window, i.e. when it is still showing unlocked, I try again to drag it. Same message.
Now I can't use Firefox at all because it has corrupted the old version I was using and I am unable to download the new one.
I am using Mac OS 10.7.2, Lion, on a MacBook Pro.

What exactly is the error you get?
How are you attempting this copy?
There's almost certainly a way to accomplish what you want to do (probably best from the terminal possibly copying the entire user dir and fixing up permissions, etc.) but I'm not sure you will end up with the results you want. There are plists in the preferences dir that you probably don't want to copy over (e.g., many of the com.apple.* prefererences). And many apps also create more than just plists. There may be stuff in Application Support, LaunchAgents, Internet Plug-Ins, etc.). And this would be stuff you do want to copy. Bottom line is it is not a trivial exercise which is probably why the system is slapping your hands for even attempting it

When I change from "remember History" to "use custom settings" it defaults back to remember history when I close the window. How do I keep my new setting?

I need 3rd party cookies enabled for a specific site. When I try to save custom settings, it defaults back to remember history and I can't open what I need on the site

Enabling thirds-party cookies is the default and if there aren't any other changes made then Firefox will show "Remember History"
Choosing the "Use custom settings for history" setting doesn't make any changes. 
If Firefox shows the "Use custom settings for history" setting then that is an indication that at least one of the history and cookie settings are not the default to make you aware that changes were If all History settings are default then you see "Firefox will: (Never) Remember History" and the custom settings are hidden.

For some reason my attempts to download free apps result in automatically opening a box that require payment info - what's wrong?? I cannot get beyond that point. when i close the box the app-icon also disappeares

i used to be able to smoothly download free apps. suddenly, also free apps open a box that require my payment info. a message tells me that i did not finish a purchase. i cannot reset the whole thing and i am also not aware of a purchase i attempted. what can i do?

Check to be sure that you don't have something that never totally downloaded - look in iTunes and in iBooks as well - not only in the app Store. A stalled or incomplete download in one of the stores can cause problems with downloads in the other stores.
You can try to reset your iTunes account by signing out of the account and then signing back in. Restart the iPad in between signing out and signing in again.
Settings>Store>Apple ID-tap the ID and sign out. Restart the iPad. Restart the iPad by holding down on the sleep button until the red slider appears and then slide to shut off. To power up hold the sleep button until the Apple logo appears and let go of the button. Go back to Settings>Store>Sign in.

When I close and reopen firefox, it restores my tabs, but it restores tabs from hours or days ago, not the ones that were open when I closed the window - why?

I normally keep my Firefox window open for long periods of time because I have a lot of active tabs. When I close the window and reopen it, I am still able to restore tabs, but as of a few weeks ago, it has stopped restoring the most recent version. Normally, when I would close and reopen, the tabs would be the same ones that were open when I closed the window. Now, it restores to a version from a few days ago instead of the current version. I have to revert to pulling my more recent tabs out of the recent history. I checked my options and I can't figure out any way to control this. How can I fix it so that I can count on my Firefox window to restore the tabs that I actually care about?

You can check for problems with the sessionstore.js and sessionstore.bak files in the Firefox Profile Folder that store session data.
Delete the sessionstore.js file and possible sessionstore-##.js files with a number and sessionstore.bak in the Firefox Profile Folder.
*Help > Troubleshooting Information > Profile Directory: Open Containing Folder
*http://kb.mozillazine.org/Profile_folder_-_Firefox
Deleting sessionstore.js will cause App Tabs and Tab Groups and open and closed (undo) tabs to get lost, so you will have to create them again (make a note or bookmark them).

When I put remember history, it doesn't stay once I close the window

I want to change my privacy setting from '''use custom setting''' to '''remember history''' and I do, but when I close the window and I open it again it shows '''use custom setting''' again. It doesn't memorize the change to '''remember history'''

MacBook Pro shuts down when i close the lid

Hey,
My MacBook Pro shuts down when i close the lid.
It started to do this one or two times, but now it is every time.
I have the latest battery update, so this should not be the issue here..
Any sugestions??
I have started to suspect the it might be some faulty conecctions or somthing..

If it's unable to go into the proper sleep state for some reason then it will do that.
Run /Utilities/Console and click 'All Messages' top left then close the lid, wait a minute then open it again - if it's shut down then reboot and open Console again and check the latest log lines looking for 'sleepimage' - it should give you an indication of what happened/didn't. If you're not sure what it all means post _just those lines_ here.

I have Firefox for U3 and lately it keeps trying to instal an update, which fails and a 2nd window tells me another copy of F'fox is running (which isn't) and when I close the window F'fox starts anyway, but all this takes a lot of time.
