When I start Firefox two copies come up
When I start the program two copies appear instead of the one I would like. The 2nd one doesn't have my tabs but does have bookmarks. I'd like to have one copy come up.
It is possible that there is a problem with the files sessionstore.js and sessionstore.bak in the Firefox Profile Folder.
Delete the files sessionstore.js [2] and sessionstore.bak in the Firefox Profile Folder.

If you see files sessionstore-##.js with a number in the left part of the name like sessionstore-1.js then delete those as well.<br />
Deleting sessionstore.js will cause App Tabs and Tab Groups and open and closed (undo) tabs to get lost, so you will have to create them again (make a note or bookmark them).

Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US) AppleWebKit/533.4 (KHTML, like Gecko) Chrome/5.0.375.125 Safari/533.4Taken at face value, you're having trouble with an Apple Application Support program file there. (Apple Application Support is where single copies of program files used by multiple different Apple programs are kept.)
Let's try something relatively simple first. Restart the PC. If you're using Vista or 7, now head into your Uninstall a program control panel, select "Apple Application Support" and then click "Repair". If you're using XP, head into your Add or Remove Programs control panel, select "Apple Application Support", click "Change" and then click "Repair".
If no joy after that, try the more rigorous uninstall/reinstall procedure from the following post. (If you've got XP, although the procedure is for Vista and 7, just read "Computer" as "My Computer", read "Uninstall a program control panel" as "Add or Remove programs control panel" and assume the system is 32-bit, and you'll be doing the right things.)

When I start Firefox it opens two instances at once
v7.0.1, running under Windows XP:
I thought the Tabbed Browsing feature looked really useful and spent an hour or so created a number of Tab Groups from my bookmarks. However, now when I start Firefox it opens two instances immediately, one correctly with my Tab Groups available but also another with just the home page. Apart from not wanting the second instance, there's now the risk that if I close the wrong one first, all of my carefully set up groups will disappear.
Something has gone wrong - how to correct it?You can try to delete the user.js in your profile folder:
https://support.mozilla.com/en-US/kb/Preferences%20are%20not%20saved
Follow steps 1 and 2 to get to the folder
If this doesn't work, try deleting user.bk as well?
(This worked for me when I deleted user.js and user.bk, although I actually copied it to my desktop first in case it didn't work.)
EDIT: When I looked at the user.js 's contents, removing the line:
user_pref("browser.startup.homepage_override.mstone", "rv:7.0.1");
also fixed the problem -

When I start firefox through shortcut icon on desktop, the message comes that Windows cannot find C:\...\jqsnotify.exe . Tried to search the file through Search also but could not find the file.
That is the Java Quick Starter, a couple of options for you:
# Open the add-ons manager (in the Tools menu select Add-ons)
# In the list of Extensions, click on Java Quick Starter to select it, then click on Disable
When you re-start Firefox that should stop the error.
The second option is to re-install Java. You are using an old version of Java so it is recommended that you install the latest version, available from http://java.com/ -
we have over 1500 firefox users and its very confusing to them if after update they start their Firefox and this "Checking Your Add-ons" window comes.
It would be much appreciated if it can somehow skipped this or do it silently.Unfortunately this link does not help.
We currently have 3.6.x versions of Firefox in most computers, and if i do a silent install via sccm to version 12, then if user starts the new firefox for the first time, it checks addons, like java quick starter and browsing protection (f-secure) etc. Second time when they start firefox, it starts normally.
My question is - is there some way to avoid this first run addon compability checking?

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:

I think I already disabled all the updating functions, yet, SOMETIMES when I start Firefox, (with about:blank), my network monitor shows one to five connections to IP addresses mostly in the 74.125.225.x, 74.125.227.x, 74.125.228.x, and 72.21.x.x ranges. Those ranges include Google, Amazon, and Youtube.
I use Kaspersky, and have scanned multiple times for malware, and even had their technical support look into my computer. They see no malware. It is the Kaspersky Network Monitor that revealed the problem.
As I find them happening, I try to jot down the addresses, (quickly, because some of these connections only last a second or two), then add those to a firewall rule I created to try to combat the problem. Yet, next time I start, new addresses are "attacking". Of course, some get away, because I don't get the address jotted down before it goes away. At one point I used masking that ended up keeping me from Google and Youtube, so I have to add the addresses individually, and my block list in that one rule is 13 items long now. The only IPs not in those ranges are 23.5.251.27, and 173.194.46.5. Not sure where those go.
I used to get attacked by addresses in the range that includes Amazon ... 72.21.x.x. I have a separate firewall rule for them that has 33 addresses being blocked.
I should not have to do all that. Firefox should start and just sit there quietly until I start clicking or typing in it. This has been happening in Firefox versions going back to 11. May have gone on before that, but I wasn't tracking it then.
Also, it doesn't always happen, or, more precisely, with addresses I have not already blocked, (because my only way to know it's happening is when the connections are allowed to be made). It does not always happen right after Firefox is up, but sometimes several minutes later. I have started Firefox and just sat and watched the network monitor without doing anything in Firefox, and have seen this happen up to 15 minutes after I start Firefox ... mostly just two or three minutes when there's a delay at all.Firefox does not do anything but sit on about:blank after I start it as long as I have a firewall rule enabled that completely blocks these subnets:
74.125.222.0/24
74.125.227.0/24
74.125.228.0/24
173.194.46.0/24
173.194.115.0/24
173.194.121.0/24
64.233.171.0/24
54.230.90.0/24
54.230.88.0/24
72.21.194.0/24
72.21.195.0/24
72.21.215.0/24
207.171.163.0/24
Otherwise, Fire fox creates connections to one to five addresses in those ranges. Note that there are more than 5 subnets above, but usually three connections satisfies whatever purpose these connections are being made for. If I had some links or whatever that is causing these connections, I would expect all of them would come up every time.
Also, these connections do not start immediately upon starting Firefox, they wait up to 15 minutes to start ... fifteen minutes of just sitting idle ... no actions on my part that could possibly initiate them. Usually these start within three minutes. A typical ploy of malware is to wait until no one is looking, or the until there's a forest to put their tree in so it won't be noticed.
While the above rules are in place, I do not have access to Amazon, Youtube, or Google, (or any of the various blog sites and services sponsored by Google, including Google Maps and Gmail). That list may not be complete, as I have other firewall rules in place that mainly block individual addresses.
It seems to me as simple as; figure out who owns those subnets, and you have your bad guys. Then go after them.
It's true that I have a bookmarks to Google, Gmail, and Youtube, but these are not "active" bookmarks nor RSS feeds. I have not voluntarily gone to Amazon on this computer.
The traffic being transmitted is unknown. It is usually not extremely large amounts of data ... less than a meg, but I have seen close to a Gig transmitted out of my computer, and over 400 meg transmitted to my computer, when I was not paying attention to block the offender. Even if it's small amounts, things like cookies, path structures, configuration settings, histories, etc. do not involve a lot of data, but, to me, represent a security breach, if someone decides to look at them unsolicited by me, not unlike your landlord, mortgage holder, or neighborhood police officer walking into your home while you're not there, and taking pictures of, or simply inventorying your belongings.
It is VERY much like some sort of backdoor malware. No malware is detected on my computer.
I looked at the suggestion above for OS changes for logging HTTP activity, but the author neglected to include instructions for backing out these changes after using them. If this were to create more jewels in a drawer the thief has access to, reformatting and restoring my drive is not the kind of back out process I enjoy. Therefore it would be foolish to apply them. To me it would be like bungee diving with no bungee. Fun until you hit the bottom. Give me the bungee, let me make sure it's short enough, then I'll dive. -
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:

I don't know what happened. All of a sudden, my settings have been changed, my homepage, and EVERYTHING. No matter how many times I go in and change them again, the SAME pages open up when I start FireFox and I am constantly being asked if I want Yahoo as my start page and default search engine. I click the box 'do not ask me again' and it comes up EVERY TIME. I change things like I don't want history remembered, and when I reload FireFox again, it's back to the way it was BEFORE. EVERY SINGLE TIME. I don't know why this is happening, or how to fix it. What do I do??
I do not want to download another virus program.. I do not believe it is a virus. I am running the full version of Norton 360 and it is doing a daily scan. I have Windows 7, 64 bit OS.
This is very irritating !! If I wanted Yahoo I would ask for it ! -
Just a few days ago, I noticed that when I start Firefox it goes to a blank page, despite the fact that I have several times checked and rechecked under "Options" and my home page is in there. Also the back button has stopped working. I have made sure that inprivate browsing is not enabled, history is maintained etc etc

When i start firefox there is a warning that I do not use the latest versionThis - http://www.google.com/firefox - is the old Firefox Start Page used by the Firefox 3.6 and earlier versions of Firefox, I don't think it is being maintained by Google.
Starting with the Firefox 4 version, Firefox is using a "local" Start Page with the address of '''about:home'''. It looks similar to the old Start Page, but it isn't exactly the same. -
When I close Firefox and then come back to it later a box comes up that says it's already running. It says to close Firefox first but when I hit close nothing happens and the box comes up again. I have to shut down my computer and restart to get into Firefox again. If I can't get this fixed I will start using someone else. Someone told me a way to close Firefox but I forgot what they said.

Every time Firefox opened
== a couple of months agoHello Brian.
You don't need to restart your computer to open Firefox again: you just need to close it manually through your application manager (CTRL+SHIFT+ESC in Processes tab). Anyway, hopefully this support article is what you need:
http://support.mozilla.com/en-US/kb/Firefox+hangs
What's probably happening is that you may be having a problem with some Firefox add-on that is hindering your Firefox's normal behavior. Have you tried disabling all add-ons (just to check), to see if Firefox goes back to normal?
Whenever you have a problem with Firefox, whatever it is, you should make sure it's not coming from one of your installed add-ons, be it an extension, a theme or a plugin. To do that easily and cleanly, run Firefox in [http://support.mozilla.com/en-US/kb/Safe+Mode safe mode] and select ''Disable all add-ons''. If the problem disappears, you know it's from an add-on. Disable them all in normal mode, and enable them one at a time until you find the source of the problem. See [http://support.mozilla.com/en-US/kb/Troubleshooting+extensions+and+themes this article] for information about troubleshooting extensions and theme. You can troubleshoot plugins the same way.
If you want support for one of your add-ons, you'll need to contact its author.
