Firefox stops responding after file download

After I download a file, Firefox stops responding and I have to wait for around 10 seconds before I can use it again.
This also happens when I'm using "Download them all"

That can be a problem with your AV software. Firefox let your default anti-virus program scan the file after the download has finished.

Firefox stops responding after everytime when launched.

Every time I launch Firefox, after a while it stops responding and it does not give me a crash report. I have tried re-installing it but no luck. I used the same add-ons for almost a year without any problems, and I have not recently downloaded anything. This started happening a couple of days ago. I have tried running it in safe mode but it still stops responding a while after I open Firefox. I am having to use another browser which does not make me happy at all.
Thanks in advance, Mustafa.

Firefox stops responding after approximately 10 seconds

Every time I open firefox it hangs after about 10 seconds and can only be closed with task manager. Task manager does not report that the application is not responding. No other applications seem to suffer from the same problem

I am also having major problems with the Firefox upgrade. Mines freezes up (says not responding) before I even try to open anything. I cannot view any videos on YouTube nor can I watch movies on Netflix (you need the Firefox browser to stream movies). Everything was working just fine until I did the upgrade.

When attempting to delete the complete "Browsing & Download History" Firefox stops responding.

Since I had not deleted my browsing history in a few months I attempted to do so today. Firefox stopped responding. After waiting around 10-15 minutes I ended the process and attempted to delete everything from "today" and it worked. I then, one by one, deleted everything for "all times" except "Browsing & Download History", and it all worked. Now all that is left is to delete this, but every time I try to delete it, and nothing else, Firefox stops responding.

How much history items do you have if the check that in the History Manager?
If there are too many then try to clear them month by month or in case you do not care to lose all history delete the places.sqlite file in the Firefox profile folder (Firefox will rebuild the bookmarks from the most recent JSON backup).
You can check for problems with the places.sqlite database file in the Firefox profile folder.

Firefox stops responding immediately after startup. I've tried all the recommended troubleshooting methods and cannot figure out why.

I have tried all of the recommended troubleshooting methods but none of them seem to work. This issue began despite no change being made to Firefox, or my computer; it just spontaneously stopped responding after launch.
Not only does Firefox stop responding, but it also prevents any other programs from being launched, and make already launched programs extremely slow. Furthermore, once it stops responding, it becomes impossible to get rid of; the only way is to log off, or restart the computer entirely.

Do a malware check with several malware scanning programs on the Windows computer.

Intermittently and without obvious pattern, Firefox stops responding and, after being closed via task manager, will not reopen unless I restart my computer.

Firefox 5 stops responding after I use it for awhile. Once I close it through the task manager, it refuses to reopen and I am forced to restart my computer to get Firefox to work again.
Note: This problem also occurred in Firefox 3 before I updated.

Try running Firefox in [[Safe Mode]]. If it functions properly in that configuration, then one of your add-ons is the culprit.

Ever since the most recent firefox update, every time I try to download anything firefox stops responding and will not do anything until I restart it. Can I revert back to a previous version, or is there a fix for it?

Every time I try to download anything firefox stops responding and will not do anything until I restart it. Can I revert back to a previous version, or is there a fix for it? When I restart firefox, then the download continues and all is well until I try to download something new (which I do quite often).

You may well find this article of interest and help in sorting out your problems: [[Installing a previous version of Firefox]] The article does contain a link for previous versions, but also points out other troubleshooting advice that may be more appropriate in some instances.
Another useful article is [[Basic Troubleshooting]]
I hope you sort out your problems either by downgrading or finding the cause of the problem.

Whenever I try to upload a file, firefox stops responding as soon as I try to select the location of the file.

Every time I try to upload a file, firefox stops responding when I try to select the location of the file. It happens in Internet Explorer as well. Any suggestions?

It happens on all sites, this one included. The "file upload" window opens for me to select a file but before a list generates, firefox stops responding. It must be my computer, since it happens with internet explorer as well, but I don't know how to fix it.

My firefox stops responding and fades for about a half min almost every hour, OR MORE often

My firefox stops responding and fades for about a half min almost every hour, OR MORE often.
I am typing a message or information, the screen fades to about half bright. the curser freezes in place and no key responds.
The information bar at the top of the page says "firefox not responding" in about 30 seconds it restores and continues as tho nothing happens.

I might have discovered the solution without starting over with all your places and bookmarks.
Right after i installed 7.0.1 over a week ago,every 10-30 min When i would be watching videos online, it would freeze for 20-30 seconds. Firefox would say ( Not responding) both firefox and the plugin container process would be very large memory files. I tried to go back to Firefox 5.0. No avail it would still freeze.I tried to disable the plugin container . no good. I tried to adjust memory or cache or plugin settings in “about:config”.Nothing fixed it!
I finally discovered why my Firefox 7.01 was periodic hanging fix. It is something to do with some of your personal files. download this this add on and install it
https://addons.mozilla.org/en-US/firefox/addon/places-maintenance/
or you can Google "places maintenance Firefox"
After you install the add on, restart Firefox.go to "tools", then "add ons" and then click “extensions” tab ,then click' options" on the "places maintenance" entry. choose "ALL' or just "expire" and hit "execute", then wait until its done., restart Firefox. should be fine then and all my bookmarks, customizations ,settings, and history stays untouched!
After i did this my Firefox did not freeze once for over 3 days straight. Might not work for everyone. I already read that Mozilla is aware of the problem and are working on a fix it in the full version of 8( the 8 beta did not fix the problem for me) . But they said this is a good temporary fix at least,( might be permanent)
For me at least ,Firefox works fine in 7 now. perfect actually.And many people i saw on similar forums had similar problems.
Enjoy. Hope this helped

Everytime I try to copy and paste, Firefox stops responding. Why?

Ever since I updated to the latest version of Firefox, if I try to copy and paste anything, Firefox stops responding. If I try to paste in another program such as Skype or AIM, that program stops responding too. What can I do to stop this?

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.
See "Disable virus scanning in Firefox preferences - Windows"

Safari and firefox stop working after a few minutes of browsing, regardless of what site I'm on. I have to restart my computer to get internet access again but it only works for a few more minutes, then I have to restart again. Please help!

Safari and firefox stop working after a few minutes of browsing, regardless of what site I'm on. I have to restart my computer to get internet access again but it only works for a few more minutes, then I have to restart again. I don't get a spinning ball, it just stops working at whatever page it's on. I can close the program just fine but when I re-open it, either safari or firefox, it freezes trying to load the hompage. This started a few days ago after trying to stream a movie on my computer. I'm on a Mac Air OS X Version 10.6.8 and have downloaded all updates. When I go into finder, it says I have over 80 gigs available. Is there some other memory cache that I need to check? Thanks so much for your help.

It's not a router problem as I explained in my post. If it was a router problem then I wouldn't have the problem everywhere I go. It is an issue with the software.
Then I guess the millions of people running 10.5.7 with no issues are just hallucinating that their machines are working fine?
I'm not trying to belittle your issues; you're certainly having them and I know first hand how annoying an intermittent AirPort issue can be. (In fact, mine was due to an AirPort driver bug that no one else seemed to suffer from.)
The single best diagnostic you could do is take your system running 10.5.7 to an Apple Store, and try using their in-store network.
If your machine performs flawlessly, it may be a router issue.
If your machine has connectivity issues there, it may be a hardware problem with your machine.
There have been numerous people in multiple threads over the years who swore that an update was buggy because things used to work, but returned later to sheepishly admit that they took their machine in, a problem was found and fixed, and now their Mac works flawlessly with the newer software.
But simply reinstalling 10.5.5 in no way means the explanation of how firmware bugs may be at play here is incorrect.
In the context of that explanation, all you've done is possibly reinstall software that asks to add "2 + 3."

Firefox stops responding while loading a specific website

Whenever I open firefox and immediately try to load the website http://www.espncricinfo.com/ , firefox stops responding. But if I try to load this site after browsing some other sites, the problem seems to resolve automatically. The website loads without any problem in Chrome or IE. I encountered this problem first with firefox 14 and with firefox 15, the problem persists.

Start Firefox in [https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode Safe Mode] and check it again to see if one of the your extensions or hardware acceleration is the problem.
Do not click the Reset button. If the problem does not happen in Safe Mode see : [https://support.mozilla.org/en-US/kb/troubleshoot-extensions-themes-to-fix-problems Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems ]
thanks again

Firefox stops responding and some times dose not start when clicked on alot!

fire fox 9 stops responding for long periods and some times dose not load when clicked on. Also please note fire fox refuses to load the comments section on Yahoo.com under the news tab. The little wheel on the bottom of the page just spins and spins and never loads this area of the page.
I think i know why but wonder since i have had issues with fire fox in the past with the whole not responding and load issues.

Firefox which stops responding after some time is a BIG problem. You're not the only one. The problem seems to be with sites which require Java. The problems I seem to have spotted is this : You visit a web site which needs Java so Java asks Firefox for the amount of memory needed and this is lent to JAVA. However, when you leave that web site, Java is naughty in that it doesn't give back the memory borrowd. Firefox then has to consume a lot of memory to the point that the whole computer system grinds to a halt as you have run out of memory.
Search in the forums for high memory or RAM and you will see many threads. In fact, when you first install Firefox it will ask if you want to send anonymous data about the memory usage!!

Mac OSX Lion: Why does PS CS6 BETA stop responding after attempting to import pdf?

Mac OSX Lion: Why does PS CS6 BETA stop responding after attempting to import single pdf or multiple pdfs? frequently happens(2/3 times)

Can you provide any more information about the files that are causing the problems? Are these particularly large files? Many pages or images? Have you opened these files in Photoshop CS5, or other versions of Photoshop?
What do you see when you try to import these PDFs? Do you get the PDF Import dialog, allowing you to select pages or images from the PDF? Is so, is it hanging when you click OK or at another time?
Any more details about the problem or other info (as well as sample files) you can provide, the easier it will be for us to help identify the cause of your problems.
