Lost files now cannot start firefox, told it is already running and cannot stop it.How can I reinstall while process is still running?

I may have deleted files that had firefox running. Cannot find them, they may have been duplicates. When trying to start firefox got message telling me firefox was already running and had to stop the process or restart pc. Tried that numerous times with no result.
Deleted and reinstall firefox several times and same thing happened.

You may have deleted the [http://kb.mozillazine.org/Profile_folder_-_Firefox Firefox Profile Folder] 
Use the Firefox profile manager to create a new profile.

Firefox 6 has crashed, and corrupted a script file in Applications Data. The result , everytime i try and start Firefox, it says its already running, but it isnt. I have tried rebooting system, removing firefox ,reinstalling and still the problem exists.

It would appear that the corrupted script files are sessionstore.js or prefs.js.
these i found in Application Data/Mozilla/Firefox/Profiles/2xewu6aw.default folder

Firefox is already running but is not responding

Check and tell if its working.

When using the same Firefox profile in Ubuntu 12.04 and Windows 8.1, how can I keep autoscrolling enabled in Firefox for Linux?

I access the same Firefox profile in Ubuntu 12.04 and Windows 8.1 (Windows fast startup disabled). I have the newest version of Firefox (26.0) on each system.
Every time I launch Firefox in Ubuntu after using the profile in Windows, I notice that autoscrolling is disabled. So I have to manually enable it every time after using my profile in Windows.
Conversely, every time I launch Firefox in Windows after using the profile in Ubuntu, I'm asked whether I would like to set Firefox as my default browser. I choose "No", first making sure that there is no check mark next to "Always perform this check when starting Firefox". I have to do this every time after using my profile in Ubuntu, despite the fact that if I check my preferences in either OS, "Always check to see if Firefox is the default browser on startup" is not enabled. Note that Firefox is my default browser in Ubuntu but not in Windows, but I have no need for Firefox to check whether it's the default every time it starts in either OS.
I don't know whether these problems are related, but it seems likely that they are. Is there a way that I can keep these settings constant, so they don't reset every time I switch operating systems?

I'm sure that when I close the browser in either OS before switching to the other, the following two conditions are true in the Advanced tab of the Firefox Preferences menu:
1) "Use autoscrolling" is enabled (with a check mark)
2) "Always check to see if Firefox is the default browser on startup" is disabled (no check mark)
The autoscrolling feature allows you to scroll by holding down the middle mouse button and moving the mouse up and down. The extension you linked to, ScrollyFox, enables scrolling by clicking a button in the Firefox UI, which is quite a different feature. So unfortunately the problems still remain.

When I try to use Google Chrome with FireFox installed my computer slows down and also crashes. How can I use both together?

I have tried several times to use Firefox and Google Chrome on my computer at the same time. When I do the computer runs slow, page scrolling is erratic, and occasionally it will crash. If I uninstall Chrome the computer returns to normal. How can I fix this issue?

You can try to disable hardware acceleration in Firefox (you need to close and restart Firefox).

Since downloading Firefox, my photo's have disappeared and replaced by numbers - How can I get the pictures back

I was having trouble with downloads on Ebay using Internet Explorer. They recommended Firefox. And it worked better. However, under My Pictures, the actual pictures disappeared and were replaced with the numbers only. I makes it difficult to remember which picture is which when you wish to download 50 or more items. I would like to have the actual pictures back rather than just the numbers. In fact, I do not have the pictures appearing that I use for Ebay. Thank you.

If images are missing then check that you aren't blocking images from some domains.
*Press the F10 key or tap the Alt key to bring up the hidden "Menu Bar" temporarily.
*Check the permissions for the domain in the currently selected tab in "Tools > Page Info > Permissions"
*Check "Tools > Page Info > Media" for blocked images
*Select the first image link and use the cursor Down key to scroll through the list.
*If an image in the list is grayed and "Block Images from..." has a check-mark then remove this check-mark to unblock images from this domain.
Make sure that you do not block (third-party) images, the permissions.default.image pref on the about:config page should be 1.
Make sure that you haven't enabled a High Contrast theme in the Windows/Mac Accessibility settings.
Make sure that you allow pages to choose their own colors.
*Tools > Options > Content : Fonts & Colors > Colors : [X] "Allow pages to choose their own colors, instead of my selections above"
Note that these settings affect background images.

There are extensions like Adblock Plus (Firefox/Tools > Add-ons > Extensions) and security software (firewall, anti-virus) that can block images and other content.

I have "hidden" my devices/USB access and now cannot figure out how to get them back on so I can re-access the USB files. How do I do this? (Is it just me, or should this be a reasonably simple task that shoul NOT require a post to the Apple community?)

Under "Devices," I have "hidden" my USB access and now cannot figure out how to re-access or "show" USB access again. Very frustrated right now--this is a high-use feature for me and it should NOT be so buried somewhere that I cannot find it. So much for Mac's "intuitive" interface.

Well, you have also "hidden" what version of OS X you are using from anyone who might want to help you.
You are probably using a newer version than I am, but I don't know that these things have changed.
In the Finder, from the Finder menu > Preferences …, there should be a Sidebar pane to choose what is visible.
Also in the Finder, Go menu > Computer (or type Shift Command C) will open a Finder window with any attached volumes showing.

I just updated to 4.0.1 on my mac and now it says "Firefox is currently in offline mode and can't browse the web". It is not my internet since I am using Safari just fine. Any suggestions? I sure wish I wouldn't have updated!

I have a video that I created for my daughter's first birthday. The hard drive on my computer crashed and I lost the video file. The only place I have it is on my iPod Classic. How can I transfer the video from my iPod to my new hard drive?

You are in luck, Refer to this recent post by tt2, on recovering media using 3rd Party Software.

If you use Windows program to partition the Hard Drive, the Apple partition gets destroyed.
Windows does not understand it is a guest on your Mac, and throws garabge wherever it pleases.

Hi chrismarks1,
I think you may be confusing bookmarks with thumbnails. If you click the Page Thumbnails icon (the one above the Bookmarks icon), then you can delete a page by clicking its thumbnail, and clicking the Delete Pages icon (the trashcan icon). Just make sure that you're viewing the PDF file in Acrobat (rather than Acrobat Reader), as you can't delete pages from Reader.
Best,
Sara

I Close Firefox. When I go back to reopen firefox. I am told it is already running, although there is nothing on my screen??

I Close Firefox. When I go back to reopen firefox. I am told it is already running, although there is nothing on my screen. I have to goto the task manager, to find firefox and shut down the process, in order to open the browser. ? a bit of a pain in the grapes, any suggestions?

Does it also happen if you wait a bit longer (1 or 2 minutes) before reopening Firefox?
Do you see hanging Firefox processes in the Task Manager (Ctrl+Alt+Del) ?

Did you press the F1 key? 
Did it only happen once?
See [[How to set the home page]] - Firefox supports multiple home pages separated by '|' symbols
Start Firefox in [[Safe Mode]] to check if one of the add-ons is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
* Don't make any changes on the Safe mode start window.

* [[Troubleshooting extensions and themes]]
