Firefox runs in background (appear in Task Manager Processes Tab) only and does not appear on Desktop

I have been using Firefox on my Desktop PC with Windows XP for a long time. However, today possibly due to some virus (I attached an infected flash drive to my PC) a suspicious change in homepage (www.delta-homes.com) of my firefox occurred. Simultaneously an error message of "WinZip" appeared on screen. I figured that there must be some software in "C:\Program Files\" which is also causing problem to my firefox. I opened Program Files and removed that folder named WinZip. (Tried to uninstall it but it won't happen so I had to use "Unlocker" to kill processes this folder was associated with and then deleted the folder.)
From that point onward, My FireFox started to behave weird. Whenever I click on Firefox icon or access firefox.exe from any source (start menu, quick launch, program files, Run Command), it starts but appears only in "Task Manager Processes Tab". In that Processes Tab, firefox.exe is continuously using 50% of CPU but it does not appear on Desktop at all.
To go a step further, I uninstalled firefox and tried to re-download from Firefox official website but the download fails in the start saying "Download is interrupted". (See attached Image). So I downloaded a previous version of Firefox (v 34.0) from www.filehippo.com and installed it but the same problem is happening with this version too.
I am confused and surprised what might be causing this problem. Everything else on PC running fine. Kindly help me restore my Firefox so that I may not lose any precious Bookmarks, Settings and other Data. thanks

Start your '''Computer''' in safe mode. Then start Firefox. Try '''Safe''' web sites.

Why do I have 2, 3, 4 copies of Firefox shown in Windows Task Manager Processes Tab?

After a few days, Firefox will get real slow, has lots of disk activity when opening a new Tab or going to another website. When I look in Task Manager, I'll see as many as 4 instances of Firefox in the Processes Tab. Even if I restart Firefox, some or all of these processes remain and I have to manually stop them to get Firefox back to speed. What is wrong or is it something I'm doing?

Hello there,
You can test to see whether one of your plugins is causing Firefox to use too much memory by selectively disabling some of them:
1. Click the menu button and choose Add-ons.
2. In the Add-ons Manager tab, select the Plugins panel.
3. Click on a plugin in the list to select it, then select Never Activate to disable it.
Repeat for some of the plugins in your list.
After disabling some of your plugins, close and restart Firefox, and observe its memory usage. If you don't see an improvement, you can enable those plugins again and try with a different set.
If none of the above solutions work then please see: https://support.mozilla.org/en-US/kb/firefox-uses-too-much-memory-ram
Hope this helps!

Firefox 4 for the Mac OSX is hanging much too often and does not respond to the "QUIT" Command for a time, i dont know if this is just me, but im running Quad Core i5 2.6ghz and 8 GB RAM the Graphics card is the Macbook Pro factory one

this happens when the browser opens websites in tabs after a period of time, i dont know how the Hang occurs but FF4 is not secure enough for me, so i downgraded to FF3.6 just for stability.

A possible cause is security software (firewall,anti-virus) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.

Trying to upgrade to V.8, cannot open Firefox. Have uninstalled, loaded 8 again then 7 , 9 and finally 6. The program will not run. Operating Windows 7. When I try to uninstall, I am asked to 'close Firefox' but it isn't open ( Task Manager confirms).

Firefox 8 won't open. The Windows 'wheel' which indicates a program is opening spins for about 5 seconds and then stops and nothing happens. I have spent several hours uninstalling and then loading different versions but still the same thing happens. I frequently switch off and restart the computer but nothing happens. I have changed the Windows firewall to allow Firefox, again nothing happens.

In the task manager, are you looking at Processes? That is where you find Firefox listed when you see no interface, not in Applications.
This page might have some useful information about that problem.

Firefox is very slow to respond when opening and nearly always stops responding altogether even refusing to react to Task Manager "End Program@ command. The "not responding@ error message also comes up during navigation on line.

Firefox is very slow to respond when opening and nearly always stops responding altogether, even refusing to react to the Task Manager "End Program" command. The "not responding" error message also comes up during navigation on line. Several attempt have to be made to get on line. A loss of stability seems to be endemic at the moment.

Try following the instructions here: [[Firefox hangs]]

When closing firefox 4, it remains active on task manager..

Firefox won't start, no error message, firefox.exe showing in Task Manager Processes

Firefox (v3.6.6 on Windows Vista) will not open. When the icon is clicked, the hourglass shows for a few seconds, goes away, and nothing else happens. There are no error messages. 'firefox.exe' shows on the Task Managers Processes tab. I also cannot open Firefox in SafeMode or with the ProfileManager.
I have tried restarting the computer, uninstalling and reinstalling firefox, deleting my firefox profile. I have tried all of these things multiple times in different orders with no results.
Please Help!

dmcritchie, thank you for your reply!
Before I received your response, I tried something that seems to have worked. I used Chrome to go to the Firefox website and downloaded Firefox (without uninstalling it first) and went through the installation process again. For some reason, this worked, even though I already had the latest version of Firefox, and I can now open Firefox successfully.
If it stops working again, I will try your suggestion. In the meantime, thank you much!

In task manager, process is named xxfirefox.exe is this legit ?

Upgraded to Firefox 9, When I look at Task Manager, the name is XXFIREFOX.exe. Has Firefox been hijacked or is this the new v4 name?

The main Firefox process is still named '''firefox.exe''' in 32-bit Windows Operating Systems.
I would be very suspicious of a process named XXFIREFOX.exe. My advice is to run a full scan with your anti-virus application, and if that doesn't find a problem do a "Search > For Files & Folders" for that executable.

How to close Acrobat.exe from the task manager processes through plug-in?

I have a plug-in in which we have a functionality of defining some keys and they are displayed as annotations on the PDF. Now, if the user defines such a key, an annot (i.e.a rectangular box) gets displayed on the PDF and if the user does not click custom menu say 'Close Key' then annot remains visible on the PDF.
My problem is if in such a case i.e. the user has defined a key & if the user does not hit 'Close Key' and instead closes Acrobat by directly hitting close (i.e. [X] button at top right corner), then Acrobat exits; but the Acrobat.exe remains running in the Processes.
If the user tries to open the same PDF again then a message pops up saying 'Cannot open file for viewing as its already in use...'.
Note that any other PDF gets opened fine.
Could somebody help me in giving me any ideas/suggestions on this? I want to exit the acrobat.exe from the processes so that the same PDF could get opened. As described above, the cause is the key (annot) was opened and user abrubtly exited Acrobat. Is there a way, that we could catch this Acrobat exit event in the plug-in? That way, I'd be able to clear off the annot (key) and then close acrobat.
Please let me know asap.

Hey, tnx for ur response! But, the issue is reproducible on Acrobat 7.0 Professional.
I do have the 'WillClose' event registered in my plug-in. Below is the event that is wired up with 'WillClose' event:-
static
ACCB1 void ACCB2 NotifyAVWillClose (AVDoc doc, void *clientData){
UNREFERENCED_PARAMETER(clientData);
UNREFERENCED_PARAMETER(doc);
CloseTemplate(TRUE);
The 'CloseTemplate' method performs the closing of the annotation, clearing of objects and deleting the PDFfile class pointer.
And this all works fine with Acrobat.exe getting closed from the task manager processes in acrobat versions 8 & 9. However, in Acrobat 7.0, the process remains in the Task Manager.
Could you suggest any ideas on what else needs to be implemented to end the process in Acrobat 7?
Thanks!

Windows 8 Task Manager Startup Tab Blank

Good Evening,
My task manager startup tab is empty, any ideas why.
Thank You,
K

That's not a fix, that's a "here use this other thing instead and ignore your problem, which is probably caused by a deeper issue creating more problems your not even aware of."
How do I (negatively) vote this down?
Do you have 3rd party tools installed which run at startup?
I suggest you to sue AutoRuns, which is much better:

Have Photoshop 7.0.1 - recently quit saving as or saving photos after changes. Just hangs until i kill process with task manager. Have uninstalled and reinstalled. Any suggestions? I don't want to upgrade to CC as I hate subscription services and often ha

Just hangs until i kill process with task manager. Have uninstalled and reinstalled. Any suggestions? I don't want to upgrade to CC as I hate subscription services and often have internet connection services interuppted.

Which operating system are you using?
Resetting the photoshop preferences might cure the problem.
Press and hold down the Shift+Ctrl+Alt keys down just after starting the launch of photoshop 7
(Shift-Command-Option on a mac)
Keep holding the keys down until you get a dialog asking if you want to delete the adobe photoshop settings file
Press Yes

Have CS6, Master Suite. The Application Manager program is corrupted and will not run. What to do?

I have CS6, Master Suite. The application manager program is corrupted and will not load. What can I do?

I'd report the problem to the iTunes Store.
Log in to the Store. Click on "Account" in your Quick Links. When you're in your Account information screen, go down to Purchase History and click "See all".
Find the item that is not downloading properly. If you can't see "Report a Problem" next to the entry, click the "Report a problem" button. Now click the "Report a Problem" link next to the item.
(Not entirely sure what happens after you click that link, but fingers crossed it should be relatively straightforward.)
