When I try to open Firefox I get a message: Mozilla Crash Reporter: firefox had a problem and crashed. Will try to restore your tabs and windows when it restarts. When I click on restore this same error box keeps appearing

I can't open Firefox and thus can't get to my.yahoo.com or any of my bookmarks.

Everything is good. Downloaded 8.0 and got fully restored - bookmarks too. Thanks for being so helpful, Swarnava.

Have you had other crashes of late? If so, post the report numbers.
'''''[https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode Start Firefox in Safe Mode]''''' {web link}
While you are in safe mode;
Press the '''<Alt>''' or '''<F10>''' key to bring up the tool bar.
Followed by;
Windows; '''Tools > Options'''

Look for and turn off '''Use Hardware Acceleration'''.
Poke around safe web sites and see if there is still a problem. Then restart.

Firefox worked before, but now, when i try to start it, i get and error "We're sorry. Firefox had a problem and crashed". I tried to reinstall it, to reboot, nothing helps.

Hi,
Firefox worked before, but one time my system crashed. When I rebooted, Firefox won't start anymore. All I got is a pop-up window, saying We're sorry. Firefox had a problem and crashed. We'll try to restore your tabs and windows when it restarts. Problem is it never restarts. When I press Restart Firefox button, I get the same message. I tried to reinstall Firefox, to make a new profile, rebooted the system, nothing works. What can be done ? Thank-you.

Of course I checked firefox crashes. I searched and haven't found my problem. I used Firefox 5 when it happened, then, seeing it doesn't work no matter what I do, I upgraded to 6. The same problem. So it's not 5 or 6 related. Computer probably wrote something to hard disk when it crashed and now the file is corrupted and prevents Firefox from starting. I don't know what file (or part of the registry) is. I could erase everything, but that would mean I will lose every Firefox settings and I don't want that. Now I am using Google Chrome to write this. I miss my Firefox. :( What else can I do ?
This is the error I get when I try to start Firefox:

I just updated to 4.0.1 and I get the "We're sorry. Firefox had a problem and crashed. We will try to open your tabs/windows when Firefox restarts" However, it just keeps popping back up, firefox never restarts!!!

This morning I had a popup on my Windows XP PC stating that the 4.0.1 update was available. I upgraded. now, i receive the following error: We're sorry. Firefox had a problem and crashed. We will try to open your tabs/windows when Firefox restarts. You can submit crash report data, blah blah blah (which i have submitted several)
But, firefox DOES NOT ever open. It just pops back up with that same report window, over and over.

It is possible that there is a problem with the files [http://kb.mozillazine.org/sessionstore.js sessionstore.js] and sessionstore.bak in the [http://kb.mozillazine.org/Profile_folder_-_Firefox Profile Folder]
Delete [http://kb.mozillazine.org/sessionstore.js sessionstore.js] and sessionstore.bak in the [http://kb.mozillazine.org/Profile_folder_-_Firefox Profile Folder]
* Help > Troubleshooting Information > Profile Directory: Open Containing 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.
Deleting sessionstore.js will cause App Tabs and Tab Groups to get lost, so you will have to create them again (make a note).

I was having the same problem.... But I keep forgetting that when you upgrade firefox... or it updates automatically... you need to right click on the firefox start up icon, go into properties, click on the compatibilities tab, and put a check in the "Run This Program As An Administrator" box, then hit apply. Start Firefox, and it should work OK. Problem is...each time you upgrade firefox and/or I think Adobe flash... you need to make sure that box is checked. This is on Firefox 15.0.1 with Adobe Flash 11.4.402.278 all up to date, Windows 7 64bit. If Firefox has Adobe flash add-on, it needs to run in admin mode or it will crash.

A Mozilla crash reporter appears. And says Firefox had a problem and crashed. What do I do?

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.

I'm getting popup notices that Firefox has a problem, and Windows is looking for a solution; then it closes Firefox and says Windows will let me know if it finds a solution. No crash report window comes up.

Firefox is my default browser on my new laptop, with OS Windows 7. I've now had several instances where a Windows popup comes up saying Firefox has developed a problem and may have to close. It also indicates Windows "is looking for a solution to the problem." No solution is found, however, and Firefox is forced to close, with the happy notice that Windows will let me know if it finds a solution to the problem. If there is any tech data on the crash, I'm not sure where to find it, and no Firefox crash report window comes up. I thought it was an anomaly the first time, but this has now occurred at least 4 times in the past several days.

Upgraded to 6.0.2, now get "Firefox had a problem and crashed". Starting in Safe Mode does not help. Now what?

Not sure what version I was running, but it worked fine but I have not been able to get it running again. I have uninstalled and reinstalled with the same results. Have followed the help pages to the point of obtaining the Crash Report... now what?
I did notice the CR seems to think I am running Windows XP but I am actually running Windows 7 (64 bit).

That gives Firefox 6.0.2 Crash Report [@ nsHttpHandler::QueryInterface(nsID const&, void**) ] https://crash-stats.mozilla.com/report/index/d2eddeb0-5845-4c72-987a-ad0282110917
Unfortunately that is not really getting anywhere yet, you could become the first person to file a bug about that particular crash, but that takes a bit of time and testing.
There is a known problem causing firefox 6 to crash and that is the use of IDvault, that can give more than one crash signature, the software developers regarding ID vault are WhiteSky, and are expecting to release a fix in a few days (if they have not already done so)
Have you tried
* using firefox's [[safe mode]]
* disabling all plugins
Does that help, either by preventing crashes or giving another recognised crash signature. You should also ensure all software is up to date, before trying adding extension software back.
The other common cause of crashes is malware, that includes a particular Trojan that is now known to crash Firefox 6. Check out [[is my firefox problem a result of malware]] you will need to do scans using software or sites with up-to-date scanning software, if you do scan for problems say what sites or software you used and the version of software used. Downgrading firefox versions rarely helps with crashes, it may help with the one specific trojan, but the security risks would then remain, potentially causing even more problems because the browser no longer crashes.

How can I prevent Firefox from cutting off the title of a webpage for use as a file name when printing/saving as PDF if there's a / in it?

Like it says in the question - when I try to print/save a webpage as a PDF, Firefox (version 36.0, Windows 8.1 64bit, German) usually uses the page's title as the file name. Slashes are, of course, not allowed in file names, but instead of just leaving leaving it out or replacing it with a hyphen, the title is cut off and everything before the last slash is gone, which in some cases results in very odd and misleading file names.
Is this a known bug? I couldn't find anything. So I'm just wondering if there's either going to be a fix anytime soon, or whether there is a simpler solution than to generate a different title sans slashes specifically for Firefox users.
Thanks in advance for Your help!

There is more than one proxy type. 
Only an anonymous proxy will hide the IP and build two connections, one between you and the proxy and a second connection between the proxy and the website that uses an IP from that proxy. 
A normal proxy merely passes all traffic without affecting it, so websites see your IP in such a case.
