Everytime I open a new tab, "You have chosen to open: Flashplayer_V.64458942b.exe" pops up.

I have deleted the file in my downloads folder. I searched in the start button pop up for the name and deleted it from there also. I have searched online but found nothing relating to this. Does anyone know how to get rid of it. I'm hesitant to uninstall and reinstall the browser...

You can check the value of the browser.newtab.url pref on the about:config page.
Try to use the SearchReset extension to reset some preferences to the default values.

Note that the SearchReset extension only runs once and then uninstalls automatically, so it won't show on the "Firefox > Add-ons" page (about:addons).
If you do not keep changes after a restart then see:

I copied this from your 5.0 download information: "All of the App Tabs you have set when you close Firefox will open as App Tabs when you start Firefox again." When I opened my computer today all my apptabs from yesterday had disappeared. Why?

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 
http://kb.mozillazine.org/Profile_in_use#Remove_the_profile_lock_file
'''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.

You have chosen to open which is a: application/octet-stream error

I have been getting his error for a very long time now:
you have chosen to open (web address here) which is a: application/octet-stream ehat should firefox do with this file? open - save
i got this from firefox 3, i tried completely uninstalling it, and then reinstalling it
and the same thing happens in firefox 4, which i just uninstalled firefox 3 and did a clean install of firefox 4
it happens randomly and periodically, it seems each new session resets the warnings, and when i click on about 35% of the websites in my speeddial, it will load that warning and a blank tab, after i click the speeddial again, it will work for that site, for the rest of the session..
it seems completely random, sometimes its google.com, sometimes mozilla.com, it could really be anything..
it could be a website in my speeddial, but it also happens sometimes when typing from the address bar
i have done extensive spyware sweeps, and antivirus sweeps for anything out of the ordinary, and i even repaired Windows XP SP2, and then I even upgraded to Windows XP SP3, i have all the updates, etc..
I have 2 computers on this network, and they both do it.
its really driving me crazy.. i even thoght about wiping my entire hard drive and reinstalling XP, but i dont want to do that
i tried IE8, but i hated the lack of speedials and tab options
and I tried Opera but i hated the fact that there were no multiple speedial tabs
and im not fond of chrome or safari for similar reasons..
i've tried a few things i've found online, but nothing really applies to this problem
does anyone have any idea how to fix this so i can keep using firefox?
thanks

After download, box which says 'you have chosen to open' 'greys out' after browse button is selected and whole page is frozen/crashed. PC restart neccesary.

Hi Firefox
After I have finished downloading a file the Mozilla Download page appears.
I right click the download to open it and the 'You Have Chosen To Open' box appears in the bottom right hand corner of the screen with the 'radio button' already selected to 'Open with..
All this so far is perfectly normal.
However if I click on the 'Browse' button to make a choice then the title at the top of the box, the closing 'cross' and the 'OK' button have all faded to grey and are inoperable.
Furthermore the whole Firefox page is frozen/crashed and can't be closed.
I have no further options than to restart the PC.
I have tried various suggestions I have found on your forums including deleting cookies, turning off the hardware accelerator, and I have uninstalled and reinstalled Firefox 12.
I have looked at your 'Troubleshooting Information' and it does show a graphics driver problem. However my driver is the lastest nVidia driver for my GeForce FX5200 card and it has worked fine with firefox 12.
WebGL RendererBlocked for your graphics driver version. Try updating your graphics driver to version 257.21 or newer.
GPU Accelerated Windows0. Blocked for your graphics driver version. Try updating your graphics driver to version 257.21 or newer.
Here is the specification of my computer:
MSI K8N Neo motherboard (N1996 MS-7030 VER:1),
an AMD Athlon (tm) 64 processor 3200+ (Socket 754)
3GB of RAM.
It has at present a NVIDIA GeForce FX 5200 graphics card.
The system is running Windows XP Professional 32bit with SP3 and all drivers are up to date.
I have used Firefox for many years and would not use anyone else browser ever!
I have not had a problem until now. I do hope you can help me.
Kind Regards
Chris

Dear mha007 Your brilliant! Now I have the correct terms it was the 'Opening' box that was freezing and it was the 'Choose Helper Application' that couldn't be accessed.
However I followed the instructions which I have cut n' pasted below and I am sure it was the 'renaming' of the rdf file that put things right.
Thank you very much I am very grateful. Kindest Regards Chris

Why is it on the photo app is that when you add your photos to new albums and when you are deleting from camera roll it will delete photos from everywhere so therefore once your photos are in the albums you have chosen you cannot delete from camera roll

Your photos are actually all in the Camera Roll. The album you create only contain pointers to these pictures. Albums are like music playlists; when you delete a song from the playlist it doesn't delete the song from your music library. But when you delete a song from your music library it will also be deleted from any playlists that it may have been in as well.

Repeated "You have chosen to open: JuniperSetupClientInstaller.exe

I have just downloaded Firefox. When I first opened it, I got the dialog box "You have chosen to open: JuniperSetupClientInstaller.exe
At the question "Would you like to save this file?", I chose Save File.
So far so good ... except, every time I open Firefox I get exactly the same dialog box.
Any ideas?
Thanks in advance,

They already have your number and/or email address and maybe have sold it several times already to others as well. They also use number generators - software that will automatically create them - some work and some don't, they don't care, they send out millions and a few will fall for it and send them money. The only way to "hide" would be to change both and your password, but then it would happen again at some point.

Everytime I open a new tab I have unwanted background music playing. win 7 64 Firefox 32.0.3

Idiotic system requires me to become a member? only thread does not post a solution to stop annoying background music when opening a new tab.
How do I stop whatever is causing background music to play when I open a new tab in Firefox 32.0.3?
I do not have any add ons....

Update Flash and Silverlight:

Shockwave Flash 13.0 r0

Also may want to reset Firefox just in case there is an issue with changed preferences.
If that is not the case I also recommend a malware scan.
Sometimes a problem with Firefox may be a result of malware installed on your computer, that you may not be aware of.
You can try these free programs to scan for malware, which work with your existing antivirus software:

When I open a new tab, I have to move to the other side of the page to click "home". Can I set the same "home" default for new tabs?

My home page opens in the initial FireFox window, but new tabs open with a blank page. To get to my default page I have to click "home", but now it's way over on the other side of the page.
Can I set a default for new tabs?

right click on the control bar and choose "adapt" (or something like that). A window will pop up. Ignore that window and move the home button to the place you want it ''on the control bar''

I cannot open any new tabs, I have done all the troubleshooting on the website, any help?

I cannot manually open a new tab. A new tab will open when clicking on a link. I have done all of the troubleshooting on the website but nothing has helped. I am using Firefox 3.6.

hello g.hill250, can you try to replicate this behaviour when you launch firefox in safe mode once? if not, maybe an addon is interfering here...

I can't open a folder in a New Tab, nor have the option to after right-click.

Basically exactly what it says on the tin.
After changing my Finder preferences back and forth, restarting, and trashing my library files to no avail, I'm wondering if anyone has a solution.
I can create new tabs, but only by using the '+' button in an open Finder window OR the File drop-down menu.

Click on the Finder window to set your keyboard focus. Now, if you press command+T, a new Finder tab will appear. This works in all four Finder views. To open an existing folder in a New Tab, it is either a right-click, or two finger Trackpad tap, on the icon –– to pop the contextual menu with the Open in New Tab option. Again, this too works in all four Finder views.
Using Mavericks.

App Tabs do not load on restart. "All of the App Tabs you have set when you close Firefox will open as App Tabs when you start Firefox again."

Use FF3 and taking a look at FF4. I set up some App Tabs. Close FF4. Open FF4. No App Tabs.
Any Help?

Are you clearing your recent history when you close Firefox?
Firefox stores App Tabs and tab group details in the same file that stores details of browsing sessions. Make sure that you have not set Firefox to delete browsing history. For details of the setting to check see https://support.mozilla.com/kb/Clear+Recent+History

Everytime I open a new tab, "You have chosen to open: Flashplayer_V.64458942b.exe" pops up.
