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.
== This happened ==
Every time Firefox opened
== July 17, 2010. After watching a video on screencastslonline.com, I noticed this as an issue. See full link below.

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.

Deleting sessionstore.js will cause App Tabs and Tab Groups and open and closed (undo) tabs to get lost and you will have to recreate them (make a note or bookmark them).

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 <u>[[Safe Mode]]</u> 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.

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.

My iMac screen keeps showing pixels of previously opened documents and Safari tabs and hour or two after closing them. The shadow of those opened documents are still there hours later after shutting down and restarting my computer. What is happening

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.

Firefox 5 keeps downloading after closing

Firefox 5 continues downloading after closing it. For example, in youtube after watching a video I close the tab. But, still my network monitor showing some thing is downloading. Then I used TCPview provided by microsoft to see who is using the bandwidth. And I see that firefox is downloading something. This is a very big problem. Please solve it fast...

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)

How do I make firefox focus on the left tab by default after closing a tab?

In all Firefox versions before 3, when closing a tab, focus automatically goes to the tab to the left of the viewed tab. This was consistent with the way Firefox opened tabs, which was to the right.
For example: I have 3 tabs, ABC.
I'm currently viewing tab B, and open a new tab using a link.
Now I have tabs ABDC, with focus on D. Once I'm finished looking at D, I close tab D and should be viewing B again. Current settings eject me to tab C, which is unrelated.
Is there a way to revert this behavior?

Firefox tabs hang when there is 3 or more

I have 3 homepages on Firefox, and they have been loading fine for the past few months. This morning when I opened Firefox, the tabs began to load but then froze. I had to end the process, restarted my computer and tried again. I had a couple successes in getting it to work: if I closed 2 of the tabs as soon as I opened Firefox it wouldn't freeze. But then I went to check my mail, and 2 minutes into it, it froze. I was able to get to the Firefox help page and started opening new tabs with different solutions on them..and it froze again.

Create a new profile as a test to check if your current profile is causing the problems.
See:
* [[Basic Troubleshooting#Make_a_new_profile|Basic Troubleshooting: Make a new profile]]
There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins"
If that new profile works then you can transfer some files from the old profile to that new profile (be careful not to copy corrupted files)
See http://kb.mozillazine.org/Transferring_data_to_a_new_profile_-_Firefox

Firefox.exe process remains after closing Firefox

I closed Firefox 5 over 45 minutes ago. At the time it closed, I had around 60 tabs open. The Firefox window closed, but now, over 30 minutes later, firefox.exe is still consuming 624 MB of memory. For the record, currently Windows Task Manager shows firefox.exe consuming 00 CPU, 639,772 K Mem Usage and a Peak Mem Usage of 771,296 K.
I'm seen this behavior at other times and, on those occasions, the firefox.exe process did eventually terminiate and release that memory. Why does firefox.exe take so long to terminate? Is this a bug or just a result of the way I use Firefox? I do tend to have a lot of tabs, 60 to 75, open at any given time. I'm guessing that's more tabs than the typical user.

I should go on to add that I have already seen the Firefox Hangs |Hang at exit document and none of these look like the obvious issue. I'm running Java Version 1.6.0_26, so current there. I'm not running any of the listed Internet security software. The only extensions I'm running are Java Console 6.0.26, ReloadEvery 5.0.0 and Xmarks 4.0.1, so not a lot of extensions.

Websites stay open in background even after closing them

Hey everyone,
I've been having issues with firefox lately. Pretty much, it seems like Firefox is keeping websites open in the background even after I 'x' them out. For instance, if I start a video on Youtube and leave it running after leaving the page.. it will continue playing in the background. If I go on facebook, I will receive facebook messenges even when it's not open on any tab. The various plug-ins for firefox never close and I have to manually force-quit them or they hog all of my CPU. The only solution I have so far is to close and restart firefox more routinely than I would like.
I'm also having a problem with entering websites into the address bar. Basically, new windows won't work for typing in websites. The solution I've found is to disable ANY of my add-ons (it doesn't matter which).. then I will be able to use the address bar for that window.
I am using the latest version of Firefox. The plug-ins I use are:
Ad block 2.64
Download status bar 10.6.0
Monitor master 5.2
No script 2.6.8.36
Open link in new tab 0.1.201407301
PDF viewer 1.0.277
Session manager 0.8.1.5
Super tab mode 1.85
URL fixer 4.1
Mac OSX 10.9.3
Please help! I want to continue using firefox but this is getting annoying!
Thanks!!

Safari opens Tabs again, even after quitting them!

Hi guys,
I'm having some annoying troubles with Safari for about 2 weeks now...
When I quit Safari, it should normally reload all my last opened pages (f.ex: google, facebook,apple and twitter), but instead it ALLWAYS reopens the same 2 tabs (some minecraft site + facebook). this is pretty annoying because it does not go away. I've allready tried everything... closing tabs with cmd-W before quitting safari, checking and unchecking the "reopen windows" setting (wich btw rechecks itself after I quit an reopen "system preferences").
anyone out there having the same problem?
please help me
thank you

Back up all data if you haven’t already done so. Before proceeding, you must be sure you can restore your system to the state it’s in now. If you skip this step, no one but you will be responsible for the consequences.
Quit Safari if it’s running.
Select /Applications/Safari in the Finder and open the Info window. There’s a checkbox in that window labeled “Open in 32-bit mode.” If that box is checked, uncheck it. Close the window.
Hold down the option key and select Go > Library from the Finder menu bar. Delete the following items from the folder that opens (some may not exist):
Caches/com.apple.Safari
Caches/Metadata/Safari
Saved Application State/com.apple.Safari.savedState
Try Safari again. If it still doesn’t work right, quit again and move the following file to the Desktop:
Safari/Bookmarks.plist
Then delete the following items (some may not exist):
Cookies/Cookies.binarycookies
Cookies/Cookies.plist
Preferences/com.apple.Safari.LSSharedFileList.plist
Preferences/com.apple.Safari.plist
Preferences/com.apple.Safari.RSS.plist
PubSub/Database
Safari
Try again. This time Safari should perform normally, but your settings will be lost. Select File > Import Bookmarks from the Safari menu bar. Import from the bookmarks file you moved to the Desktop. Recreate the rest of your Safari settings. You can then delete the old bookmarks file.

Certain applications re-open at login even after closing them

Hi there esteemed support-forum users! Hopefully someone might be able to help me out with this before I resort to the Genius Bar.
I'm running Lion on my new MBP (13" 2.7GHz i7 4GB, not that I think it matters) and have been impressed with the GUI improvements overall, and most of the features it offers. However, there are a couple of small niggles which are gradually escalating into annoyances.
The first of which, is that on login I'm greeted with VLC, iTunes, and Safari all auto-running. I assumed this was due to Lion's 'reopen windows' feature, since none of them are in the 'login items' list on sysprefs. However, on restarting with the check-box for reopening windows turned off, they still appear. This regardless of whether I manually quit the applications first.
Also, after these applications open there's a 30 second or so pause, before a Finder window opens up directed at a random folder inside the package contents of the Steam application. Similarly to the applications, this window appears even if I manually close it, turn off 'reopen windows', and restart.
Any help greatly appreciated. Bit disappointed that there are problems this obvious with Lion (can't really use the "it's a brand new OS" excuse anymore).
Cheers!

Hi there,
Thanks for the help. It didn't fix it: but I have since worked out what the problem was.
As well as the login issues, Finder was consistently forgetting that I had changed my desktop background to something other than the Lion-galaxy. I had thought this was a different issue: but then I noticed that between logins it had also forgotten my Finder-side-bar rearrangement and some Firewall changes.
I guessed such changes would be stored in the user library, and I had been having some problems with permissions previously. So I un-hid the User->Library folder and ran 'ACL Repair' on it. Sure enough everything now works smoothly. I hope!

Why does firefox continue to run after closing it?

I close out of an internet site and then go to another link and I get the box that says "Firefox is still running," I wait and try again and it still tells me this.I try several times,I then reboot and start over.How do I stop this?

Probably a problematic extension can cause the problem, see : [https://support.mozilla.org/en-US/kb/Firefox-hangs#w_firefox-hangs-when-you-quit-it Firefox hangs when you quit it]
thank you
Please mark "Solved" the answer that really solve the problem, to help others with a similar problem.

Firefox continually hangs even after trying the solutions listed here, and in other sites, and I can't find any common link to pinpoint what is causing it.

I love Firefox but I may have no choice but to try Chrome instead. Over the past couple of weeks the version of Firefox I have installed on my Lenovo Edge 15 latop (which is the most current version of Firefoxc), hangs several times an hour, for approx a minute each time. I have tried to locate the cause of the problem by eliminating the websites I commonly visit, but it seems that it does not matter what website I visit, it continues to happen. I have even tried loading Firefox in safe mode and it still makes no difference. And this problem is only affecting Firefox, and none of my other programs are affected. I have used resource monitor to try and locate the problem and, when this problem occurs, Firefox is reported as taking up 25% of CPU consumption. I am using Windows 7.

I have a Mac and have tried the suggestion above with the places.sqlite but it DID NOT HELP! FIREFOX IS STILL HANGING!!!!!!!!!!!! I've been a real fan of firefox for several years, but lately it's just plain annoying!!! I have to force quit FF several times a day. I THINK I'M GOING TO SWITCH TO SAFARI until you guys get your act together soon :(
