When I start Firefox, one tab overwrites another.
Many times when I open Firefox, one of my open tabs loads as something that is or has been in a different tab. (Usually it's something that's currently open, but occasionally it's something that's been open in the last couple of days.) The tab history belongs to the new tab; I can only get back to the old tab by typing in the URL. Most often, the overwritten tab is the one furthest to the left, but not always.
I originally though this was either an app tab or Gmail thing but since I've stopped using an app tab and leaving Gmail open, other tabs have taken the role of the new tab.
Occasionally a tab also gets overwritten when I refresh it in the middle of a session.
This problem only seems to occur with my main tab group; I have never seen it happen with other tab groups. In addition, I also use Firefox on Windows, and have never had the same problem there.
I first noticed this problem with Firefox 6, if I recall correctly; it was whenever app tabs were first introduced.
I have tried disabling all my plugins one at a time and it didn't help.
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.

when using more than one tab, once I have opened a .pdf using firefox my laptop will not allow me to type or click in another tab unless I drag the .pdf into it's own window? not a major problem just irritating.
I found the cause but no solution, it's actually a plugin that does that: divx plus weblpayer (it gets installed when you install DivX on your system), if you disable it and restart firefox it all works again. But I want that plugin... so DivX need to fix this, unless it is a Firefox bug in its own core... anyway these two together creates the problem.
(I'm running Firefox 9.x on OSX Lion)
I also wish firefox tab tear out tab worked more like chrome's tab tear out, much friendlier... -
When i start Firefox ( 5.0.1 ) it loads the home page fine but along with it, it starts playing a video i watched earlier on youtube and it is invisible ( no where in tabs ) and i can just hear the sound. After playing the video one time it stops.
Sorry you are having problems. First of all try Fifrefox's safemode.
*[[Troubleshoot Firefox issues using Safe Mode]]
If that works post back for further advice.
Next step, if safe mode did not work.
<u>First: Try a clean install, <sub>(you have had a none standard version installed previously)</sub></u><br /> that involves deleting the program files. Then if necessary try troubleshooting by creating and using a clean empty Firefox profile.
See
* this recent post [/questions/940399#answer-377134]
* http://kb.mozillazine.org/Standard_diagnostic_-_Firefox#Clean_reinstall
<u>Second: try a New Profile</u>
*http://kb.mozillazine.org/Profile_Manager#Creating_a_new_profile
* this will be an additional profile, it is still worth backing up any existing or currently working profile on a regular basis
**[[Back up and restore information in Firefox profiles]]
* Until you are absolutely confident about the repercussions I suggest
** always use an empty folder when creating a new profile
** never delete or rename profiles, just disable or remove shortcuts
** after creating a new test profile open it and check for any addons or plugins that may be have been included by default -
I have google toolbar installed on my Firefox 4, whenever I start firefox two tabs open, one is my homepage gmail and the other is "google toolbar updated".
How can I stop the second tab from opening?See these articles for some suggestions:

Your download page for 5.0 stated: All of the App Tabs you have set when you close Firefox will open as App Tabs when you start Firefox again.
I liked the convenience of using App Tabs and was disappointed to find that the ones I had set up yesterday were gone today. Am I doing something wrong?Works fine for me, I can simulate your problem by improperly closing Firefox.
The correct way would be to close the windows you don't want and then to exit Firefox through the File ("'''Alt+F'''") menu then use '''Exit''' or '''Qui'''t depending on your system.
But '''I can simulate your problem''' by closing the good window with "X" in the upper right-corner first (the one with the app-tabs) and then close the other window by any means.
You restart Firefox and open a window, since you closed without app-tabs there are none so you just see a window with your home page.
Firefox has some things added to Firefox 4 and therefore in Firefox 5.
# "'''Alt+S'''" (Hi'''s'''tory menu)
# "'''Restore Previous Session'''" (that's the window without the app-tabs, but you have to this first)
# "'''Restore Recently Closed Windows'''" -- can choose which window to reopen based on name and the mouse-over tells how many tabs. or you just use "'''Restore All Windows'''" without the guessing.
''I know you are on a Mac, and this affects Windows user more than anybody else, but it does affect other systems besides Windows, occasionally, perhaps more often now with the plugins container.''
The following may not completely eliminate having to terminate Firefox through the Windows Control Panel but it will come very close.
'''Plug-in and tasks started by Firefox may continue after attempting
to close Firefox''' The "X" in the upper right-hand corner closes the
Window (same as Ctrl+Shift+W) but even if it is the last Firefox window,
it does not necessarily close Firefox .
The only '''proper way to exit Firefox''' is to use '''Exit''' through the
File menu, not the "X" in the upper right corner of last Firefox window.
In the Firefox 4 and 5 that would be Alt+F then X

Use the '''Windows Task Manger''' to remove all running firefox.exe in the "'''Processes'''" tab of the Windows Task Manager, then restart Firefox.
If Firefox will still not start, remove the parent.lock file from the profile which is created each time Firefox is started to prevent other Firefox tasks from running, see<br>

'''Avoiding Problems with close/restart''' ''choose either extension''
:Use to close and restart Firefox after enabling or disabling an extension, switching to a new theme, or modifying configuration files, then you don't have to worry about delay or have to look in the Task Manager to see if Firefox is closed yet.
Both extensions use the same keyboard shortcut "'''Ctrl+Alt+R'''" or a file menu option.

I have Google as my default home page in Firefox and the Google browser opens when I start Firefox, but every time I open a new tab it opens the Yahoo browser.
Do you have the FastStart extension?
Start Firefox in <u>[[Safe Mode|Safe Mode]]</u> to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.

Make firefox start with one tab using mozilla.cfg
i create new package for fire fox when start firefox it is open two tabs for same link
i need it to start with one tab i use the this in my mozilla.cfg :
<pre><nowiki>defaultPref("startup.homepage_welcome_url", "https://portal.field.weightwatchers.ca/");
defaultPref("startup.homepage_override_url", "https://portal.field.weightwatchers.ca/");
defaultPref("browser.startup.homepage", "data:text/plain,browser.startup.homepage=https://portal.field.weightwatchers.ca/");</nowiki></pre>When do you want to see this page?
This only sets the default home page, so if users have change this setting then it won't have effect.<br />
If you use pref() then you set this pref for the current session, but this will make it impossible to make changes that last across a session.
You also may want to set to open the Home page on startup (browser.startup.page = 1).

I like to be able to close the webpage I am viewing when I am finished, when there is only one tab open, so that Firefox is empty when I next want to browse the web. After upgrading to 5.0 and finding I hated it, I downgraded back to 3.6 and now the little "x" on the single tab is gone. It still appears when I have multiple tabs open, but not when there is just one. What happened? How do I get it back?
Thank you, but I already have "always show tabs bar" set.
Also, I have two computers and the other is running the exact same version of Firefox, and the exact same theme, but it does not have this problem.
To make sure I'm being clear: there is an "x" on each tab that allows me to close it when I have multiple tabs open. When I have only one tab open, there is no "x"; so in order to close the webpage I have to open another empty tab, and then close the first. My other computer has the "x" to close the tab visible even when there is only one tab so that I can close the page and have an empty (marked "(untitled)" tab). Please help! -
When I start firefox, the previous tabs are there but blank and say new tab, can I restore the tabs?
When I start firefox, the previous tabs are there but blank and say new tab, can I restore the tabs?
how can I do this?I'm not sure what causes this.
As the first step, I recommend backing up your existing sessionstore files.
Open your current Firefox settings (AKA Firefox profile) folder using
Help > Troubleshooting Information > "Show Folder" button
Scroll down to the files whose names start with sessionstore. You should find at least sessionstore.js and sessionstore.bak. If the .js extension does not appear on sessionstore, you should turn off the Windows feature that hides file extensions from you, so that you can work with file names as accurately as possible. This Microsoft support article has the steps: [http://support.microsoft.com/kb/865219].
Make backup copies of all the sessionstore files to somewhere like your Documents folder for possible later restoration.
Next, try one of the data mining techniques in these posts to rescue the URLs from the sessionstore.js or sessionstore.bak file:

Tabs from last session aren't opening when I start FireFox
In options I have Show my windows and tabs from last time set for When Firefox starts. And I unchecked the warn me when closing multiple tabs option (although it was previously checked, and it wasn't warning me when it was checked).
The last few days I have had 1 window with 4 tabs open (each to a different site) when I exited Firefox. The next day when I start firefox it ends up opening 4 windows each showing about:blank. My tabs are not restored.
I have NOT cleared my history or any other information.Who was the pop-up offer from?

When I start Firefox 4.0 my previously set App Tabs don't re-open
Using Firefox 4.0 under Win XP Home SP3 I do "Pin as App Tab" to several tabs. When I restart Firefox those tabs do not open, either normally or as App Tabs. What do I need to do to make them re-open automatically on re-start?
You're welcome! I will try to get these details added to the documentation for App Tabs.
<BR><BR>Please click on the '''Solved''' button to mark this question as solved for the benefit of other users. Thanks. -
I've just started using the App Tabs. I think this feature could be handy but why are the sites not updated when I start Firefox. Now I have to manually update the site which is somewhat of a downer. Does any of you know where I'm going wrong?
To answer the post title FireFox save all downloads automatically in the download folder, which you can find in the Documents folder. If you want to choose where to save your downloads go to tools>options>check always ask me where to save files.
Secondly, I am assuming you have IE 8 installed as this is the only version that supports this fix that is currently not in beta. Go to control panel>internet options>advanced tab and reset the settings at the bottom. This may or may not fix the problem but it is a good first step. -
When I start firefox, I get a Dialogue bx saying that Firefox had stopped working and Windows is checking the cause, another dialouge box says that A problem caused the program to stop working correctly. Windows will close the program and notify if a solution is found,the problem continues, I have Google Chrome working on my Laptop.
It is possible that your anti-virus software is corrupting the downloaded files or otherwise interfering with downloading files by Firefox.
Try to disable the real-time (live) scanning of files in your anti-virus software temporarily to see if that makes downloading work.

See http://kb.mozillazine.org/Software_Update (Software Update not working properly)
Remove the files in the updates and updates\0 folder:
C:\Users\<user>\AppData\Local\Mozilla\Firefox\Mozilla Firefox\updates
(%LOCALAPPDATA%\Mozilla\Firefox\Mozilla Firefox\updates)
Do a clean reinstall:
* Download a fresh Firefox copy from http://www.mozilla.com/firefox/all.html and save the file to the desktop.
* Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
* Don't remove personal data when uninstalling.
* It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
Your bookmarks and other profile data are stored elsewhere (not in the Firefox program folder) and won't be affected by a reinstall, but make sure that you do not select to remove personal data if you uninstall Firefox.
