Some tabs remain open after closing them

When I have opened a lot of tabs (10+) and I close them afterwards, sometimes a few of those tabs will still show in the tab bar. When I click them I can't view them though. It seems to be a problem with the tab bar, not with web pages.

Start Firefox in [[Safe Mode]] to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance/Themes).
*Don't make any changes on the Safe mode start window.

How do i get the download window to remain open after closing firefox browser window

i sometimes download a bunch of files all at ones then have to go back to review them. but i don't need the browser open to do this just the download window. in older versions the download window would remain open after i closed the browser but i don't see a way to do that anymore?

Firefox tabs hang around after closing them

When I have multiple tabs open, and I close a tab, the tab browser still shows the page of the closed tab, while the tab is removed from the tab bar. The only way of changing the view is to navigate to the next tab. If there is a flash playing on the page, it continues to play until it's finished, even after you navigate to the next tab.

Tabs being restored after closing them

Ever since i upgraded to one of the recent FF versions, i noticed this rather odd behaviour.
Lets say i have tab 1, followed by tabs 2-10 open. I close tab 1. At some point, i'm not sure when exactly, but i will notice that tab 1 is open again, but it will be positioned as the last tab.
What's going on here? I have no addons that could do this.

Cursors remained open after closing connection

I am using OC4J 10g (Application Server) and Oracle10g DB. OC4J is maintaining the connection pool(com.evermind.sql.DriverManagerDataSource). I get the connection from pool and call DB procedure, then close resultset, statement and connection. It closes the opened cursors against resultset. But left some implicit cursors opened and never closed so cursor count is going to increase.
If i dont use pool no cursor remained open and count is zero. It means the cursors of pooled connections are not closed.
wait-timeout="60"
min-connections="5"
max-connections="100"
inactivity-timeout="15"
<property name="stmt-cache-size" value="2000"/>

Hi Justin,
Thnx for your reply and you're understanding is correct but the problem I face is when multiple concurrent users access the JSP page from which I'm actually calling the servlet to retrieve the image, the number of cursors being left open increases. As the load on the page increases (i.e. no of usesrs increase) oracle seems to have problems in garbage collecting the open cursors ... which eventually leads it to throw maximum cursors exceeded exceptions.
Any suggestions ?

Why do ports remain open after closing Firefox?

I have noticed recently that several ports associated with Firefox remain open when the Firefox browser is closed. The number of open ports increases each time Firefox is opened and I have seen that the number of open ports has reached to more than 1,000 open ports at a time. The majority of the open ports are outbound TCP using port 443 and I also note a sustained increase in the network traffic after Firefox is closed.
I have observed ports opened by the Explorer browser and noted that all of the ports opened with Explorer close when the Explorer browser is closed. The Firefox ports remain open when the browser is closed.
Questions:
- Should all open ports associated with an open Firefox browser close when the Firefox browser is closed?
- Does Firefox have a setting that closes all open ports when the Firefox browser is closed?
- Does XP have a setting that will close all open ports associated with Firefox when Firefox is closed?
- Should I have security concerns about the accumulating open ports and increased network activity when using Firefox?
Thanks.

My iMac screen keeps showing pixels of previously opened documents and Safari tabs and hour or two after closing them.
Even when I swipe to the dashboard the outlines are still there when I know they should not be.
The shadow of those opened documents are still there hours later after shutting down and restarting my computer.
What is happening and what shall I do? Thanks in advance.

when two or more tabs are opened after this when I click on another tab which is opened then firefox stopped responding and open automatically all the tabs in different windows

If it works in a new window then you can drags tabs from the not working window to that new window.
You can also try to close the tabs via Ctrl+W and restore the closed tabs via Shift+Ctrl+T

High memory usage when many tabs are open (and closed)

When I open Firefox the memory usage is about 70-100 MB RAM. When I'm working with Firefox I often open 15-20 tabs at once, then I close them and open others. Memory usage increaes up to 450 - 500 MB RAM. After closing the tabs the usage usually decreases, but after sometime. It starts decreasing very slow and never comes back to the level from the beginning. After few hours of work Firefox uses about 400 MB RAM even if one tab is open. First I thought it's because of my plugins (Firebug, Speed Dial, Adlock Plus) but I've checked it and it's not. I reinstalled Firefox but the problem occurs as well. I'm not sure if it's normal. Could you help me, please?

Hi,
Not an exact answer but please [http://kb.mozillazine.org/Reducing_memory_usage_(Firefox) see this.] The KB article ponders through various general situations which may or may not be applicable to specific instances but nevertheless could be helpful.

My Firefox.exe process remain open after I close the browser.If I open it it's says to open a new window.I need to close the process manualy(Ctrl+Alt+del).What can I do?Thanks .

Need to close the process.

It does take Firefox a while to shut down; it has to update some databases. But it should take less than a minute.
In the support article, this problem is called a "hang at exit" because Firefox hangs when shutting down. Maybe something here will help: https://support.mozilla.com/en-US/kb/Firefox+hangs#Hang_at_exit
Also, sometimes open Firefox windows disappear from the Task Bar. You can use Alt+Tab to switch to them if they remain open.

How to stop tabs re-opening after firefox crashes.........when it crashes and I have multiple tabs open, when re-starting firefox all of the tabs re-open too. How can I stop this?

Firefox crashes quite often, especially when I have multi tabs open. I usually have to use CTRL ALT DEL and end the process as Firefox stops responding.
My problem is not the crashing........it is the re-opening of the multiple tabs I had open, when normally it is one of them (not the home page) that caused the crash in the first place, so I cannot re-open firefox until I restart the pc, because every time I do it is the same story. Firefox tries to re-open all of the tabs and stops responding. I have looked in options but nowhere does it allow me to stop multiple tabs opening after a crash. If this continues, I will have to uninstall Firefox and stick to Chrome.

Set the pref browser.sessionstore.max_resumed_crashes to 0 on the about:config page to get the about:sessionrestore page immediately with the first restart after a crash has occurred or the Task Manager was used to close Firefox.
*http://kb.mozillazine.org/browser.sessionstore.max_resumed_crashes
That will allow you to deselect the tab(s) that you do not want to reopen, but will allow to reopen other tabs.

Losing windows from Firefox after closing them.

I have been using Firefox instead of Chrome for a long time as with Firefox it is easier to navigate through my tabs (unlike Chrome that lumps them together -- you can't even see the title of each tab if you have say, 20 tabs) and the fact that firefox only loads tabs on demand -- which saves me a lot of lag compared to Chrome that loads all tabs when you start it.
I'm an avid online shopper so I tend to open up close to 40 tabs per session/window for shopping, and then I would have another window open to do my work. Usually, I set my settings to 'Open tabs and windows from previous session' so I can open up my first window, then go to 'Recently closed windows' to open my second. It has been working perfectly, until today when my Firefox got updated. I would completely lose my first window no matter how much 'System restore' I did on my computer. (I close my windows in the sequence of second-first so that I can opne it the same way again)
Is there a way to fix this problem? I would hate to lose my important tabs and it would be a hassle if I had to mix the two together.

Which Operating System are you using as you appear to have posted with a mobile device?
It is best to use Firefox/File > Exit if you want to preserve all open windows.
If you first close each of the other windows then only the last closed window will be reopened.
Maybe Firefox updated to 25.0.1 and that has caused this to happen (a restart with only the last window opening)

Sockets remaining open after connection failure

Hi - I have a multithreaded application that runs as a daemon (always up) and uses OCI (10.2.0, 64-bit client). If a database connection or query fails for any reason, it is coded to keep on retrying on a set schedule until it succeeds. The application runs on RHEL 4 (64-bit) and is compiled with g++ 3.4.6. (It's nominally C++, but is really what I call "C with objects" as it doesn't use a lot of the standard C++-isms, though there are objects -- the OCI code in question is in a C++ object wrapper that I wrote.)
Anyway, about 5 days ago, the database where most of the queries are run went down (it's a 10g server; I don't remember the exact version, but since it's down, I'm not sure it matters), and it has not come back up, although the hosts it runs on are up. Meanwhile, my application kept failing to connect and retrying, and the number of queries that this was happening to kept on growing as new ones are added every day. Unknown to me, the failed connection attempts were leaving open TCP sockets to the database that was down, until eventually the maximum open files on the system was exceeded and I was forced to reboot. Twice. (It happened again the next day.)
From what I can tell, I am properly dropping the handles and such when a connection fails, so why are the sockets staying open? Is there anything that can be done to force the socket to close after a failed connect? This morning I changed all the queries to use a different database (that's actually up), but according to lsof, there are still 56 open sockets to the old (non-working) database, even though none of my program threads are actively trying to connect there anymore.
The sockets do close, by the way, if the application is stopped and restarted. But they remain open as long as the instance that created them is still running. (I added a periodic restart to clean things up, but I'd really like to fix the problem instead of using a stopgap like this!)
Sample code is below. This first bit is what is used to connect and log in. (Note that I have this mutex-locked -- I know OCI is supposed to be thread-safe if you use the OCI_THREADED attribute, but I've been having so many issues that I thought it was safer.)
if (check_err(OCIEnvCreate(&env, (OCI_THREADED), (void *) 0, 0, 0, 0, (size_t) 0, (void **) 0)) != 0)
fprintf(stderr, "Error allocating OCI environment handle\n");
return;
// Allocate error handle.
if (check_err(OCIHandleAlloc((void *) env, (void **) &err, OCI_HTYPE_ERROR, 0, (void **) 0)) != 0)
fprintf(stderr, "Error creating OCI error handle.\n");
return;
// Allocate server handle.
if (check_err(OCIHandleAlloc((void *) env, (void **) &server, OCI_HTYPE_SERVER, 0, (void **) 0)) != 0)
fprintf(stderr, "Error allocating OCI server handle.\n");
return;
// Allocate service handle.
if (check_err(OCIHandleAlloc((void *) env, (void **) &svc, OCI_HTYPE_SVCCTX, 0, (void **) 0)) != 0)
fprintf(stderr, "Error allocating OCI service handle.\n");
return;
[Note: these are snippets from two different functions; this is a C++ wrapper that uses OCI, so the above code is in the database object constructor, and below is a separate login function.]
// Attach to server.
retcode = OCIServerAttach(server, err, (text *) curDS, strlen(curDS), OCI_DEFAULT);
if (check_err(retcode))
fprintf(stderr, "Error attaching to Oracle server.\n");
return(retcode);
// Set server attribute in service handle.
retcode = OCIAttrSet((void *) svc, OCI_HTYPE_SVCCTX, (void *) server, 0, OCI_ATTR_SERVER, err);
if (check_err(retcode))
fprintf(stderr, "Error setting OCI server attribute.\n");
return(retcode);
// Allocate session handle.
retcode = OCIHandleAlloc((void *) env, (void **) &sess, OCI_HTYPE_SESSION, 0, (void **) 0);
if (check_err(retcode))
fprintf(stderr, "Error allocating OCI session handle.\n");
return(retcode);
// Set username attribute in session handle.
retcode = OCIAttrSet((void *) sess, OCI_HTYPE_SESSION, (void *) curUser, strlen(curUser), OCI_ATTR_USERNAME, err);
if (check_err(retcode))
fprintf(stderr, "Error setting OCI username.\n");
return(retcode);
// Set password attribute in session handle.
retcode = OCIAttrSet((void *) sess, OCI_HTYPE_SESSION, (void *) curPass, strlen(curPass), OCI_ATTR_PASSWORD, err);
if (check_err(retcode))
fprintf(stderr, "Error setting OCI password.\n");
return(retcode);
// Start session.
retcode = OCISessionBegin(svc, err, sess, OCI_CRED_RDBMS, OCI_DEFAULT);
if (check_err(retcode) != 0)
return(retcode);
// Set session attribute in service handle
retcode = OCIAttrSet((void *) svc, OCI_HTYPE_SVCCTX, (void *) sess, 0, OCI_ATTR_SESSION, err);
if (check_err(retcode))
fprintf(stderr, "Error setting OCI session attribute.\n");
return(retcode);
If any of the above calls returns an error, the next call is to the database object destructor (also mutexed), which looks like this:
if (connected && svc && err && sess && check_err(OCISessionEnd(svc, err, sess, OCI_DEFAULT)))
fprintf(stderr, "Oracle - Error ending session\n");
if (connected && server && err && check_err(OCIServerDetach(server, err, OCI_DEFAULT)))
fprintf(stderr, "Oracle - Error detaching from server\n");
if (connected && server && check_err(OCIHandleFree((void *) server, OCI_HTYPE_SERVER)))
fprintf(stderr, "Oracle - Error freeing server handle\n");
if (connected && svc && check_err(OCIHandleFree((void *) svc, OCI_HTYPE_SVCCTX)))
fprintf(stderr, "Oracle - Error freeing service handle\n");
if (connected && err && check_err(OCIHandleFree((void *) err, OCI_HTYPE_ERROR)))
fprintf(stderr, "Oracle - Error freeing error handle\n");
if (connected && env && check_err(OCIHandleFree((void *) env, OCI_HTYPE_ENV)))
fprintf(stderr, "Oracle - Error freeing environment handle\n");
Anyone else had this happen? Any insights/help would be greatly appreciated!
Oh, one more note: though the application is multithreaded, none of the database objects or connections is shared -- each thread makes its own connections and maintains database objects separately. I added the mutex locks because Helgrind was reporting race conditions on handle allocations and deallocations.
Thanks,
--Tina

Hmm, I believe I did have an OCIHandleFree on the session handle in an earlier version of the code. I can't remember why I took it out, but I do remember that there was a reason -- it was causing a problem. (Yeah, I know, vague enough for ya?) Anyway, the OCI documentation said that when you call OCIHandleFree on the environment handle, any child handles would be implicitly freed, so I assumed it wouldn't be a problem. Still, I'll try putting it back and see what happens. Thanks.
Oh, and to answer your question (about netstat), it said the processes were ESTABLISHED. But the Oracle server was down (although the hosts it resided on were up). The connection attempt failed with the error message:
ORA-01034: ORACLE not available
ORA-27101: shared memory realm does not exist

Adobe XI remains open after printing from command line

I am using a program to collect, batch print and delete multiple PDF files.
The following command line is used to print the files, after which the file is deleted and next file is collected.
"C:\Program Files\Adobe\Reader 11.0\Reader\AcroRd32.exe" /T /N FileName.pdf
I have now upgraded to Adobe XI, however Adobe remains open (and minimized) after sending the print job to the printer, resulting in my programing freezing while waiting to delete.
Is there a parameter to close Adobe after printing?
This is rather urgent as we have started rolling out the new Adobe XI.
OS = Windows7 Prof x64

Command line parameters are sparsely documented and are officially not supported. What is documented can be found here: http://partners.adobe.com/public/developer/en/acrobat/sdk/pdf/intro_to_sdk/DeveloperFAQ.pd f
I've not seen anything that shows what you want to do.

ITunes Unexpectedly Re-Opens after Closing

I just reformatted my laptop and upon installing iTunes 6.0.3.5, I noticed that iTunes, after closing it, will relaunch a few times, usually two.
I figured maybe it was something with the software version, so I just updated to 6.0.4 and it does the exact same thing. I never did this before I cleaned off my laptop and I was curious to see if anyone else had a similar problem, and hopefully a solution.
