I've been using firefox for a really really long time, and I play quite a lot of facebook games. Yesterday morning, things were working perfectly fine, but later in the day, I suddenly started getting these shockwave errors. I can't recall downloading anything and I must have uninstalled and reinstalled the flash player at least 8 times. It's honestly starting to frustrate me. I love firefox, but if the browser refuses to work, I probably won't be using it for much longer.

I get the following message:the ordinal 459 could not be located in the dynamic link library. urlmon.dll. I get this when requesting list links within a genealogy program (not on the internet) Haven't noticed it on anything else yet because I have been obsessing over just that one program. At the same time I notice that my windows sidebar is not visible. Have not changed any settings. Java was disabled due to the recent exploitation. Would that have something to do with it. Or perhaps Firefox18 installed and then it went bad? Thanks in advance for any help. Running Vista.

My Firefox crashes when trying to open 75% of web pages. I get the windows standard "Firefox is not responding" window after it freezes while trying to load the page.

I have singled out the problem to be the Shockwave Flash (11.5.502.149) plugin as everything works correctly with this disabled.

I have tried updated flash, uninstalling and re-installing it and the same with FF but nothing seems to work so far.

This "Untrusted Connection" thing is god-damned annoying. Websites that I've been using for YEARS... all of a sudden are "untrusted." I don't ***-**** care. How do I turn this feature off?

Unable to login gmail. After entering user name and password, says, Your browser's cookie functionality is turned off. Please turn it on. Even after clearing cache and cookies, enabling cookies, starting firefox in safemode, resetting firefox, Says the Same thing. I have tried all troubleshooting information provided by mozilla support and all were unsuccessful in solving the problem. I have the same problem with internet explorer and chrome also.

Firefox suddenly has become very slow. It takes too much time to load all websites and even the typed words and scrolling has a great delay in appearing. It becomes unresponsive very often. I tried reinstalling it and even reset it. Its becoming a pain to use this to surf the net. Please do help!!

I have a Windows 8 laptop on the Beta channel. I updated to Firefox 22 Beta yesterday and noticed that the Roboform toolbox was missing. I reinstalled Roboform, just to make sure, but it was not present in the browser windows, nor is it on the Toolbar menu. It does show as an installed add-in, and the toolbar is present in I.E. 10 and Chrome.

I have my system set to minimise windows by double-tapping/clicking them on the title bar. It works for most of windows (iTunes being exception). It's a system preference thingy, so it should work across all the board. After the recent update to 21.0, my Firefox is unable to minimise by double-tapping on the title bar anymore. Is there anyway to fix this issue, or will this be solved in the next update?

I just loaded windows 8 onto my system and placed Firefox version 19. as my web browser and went to Youtube and updated flash to the Version it was looking for which in this case is 11.6 r602 and now everywhere that I go on the web the plug in pops up says it fails and locks up my firefox. I have done what the suggestions have said

1. Made sure system was up to date 2. Lowered hardware and flash acceleration 3. changed firefox settings 4. have done numerous re-installs of firefox and flash

I had to start using google chrome Please help I like fire fox better

I am having trouble getting Java to work in Firefox (Opera too) on Mac. http://www.java.com/en/download/installed.jsp?detect=jre tells me "We are unable to verify if Java is currently installed and enabled in your browser." Notice that when I access the page, Firefox wants me to activate Java in a pop-up. I did this.

I know that Java is installed because I can open the Java Control Panel. The setting "Enable Java content in the browser" is checked and Security Level is set to High. I have tried setting the security level to a lower setting, but that doesn't help.

I have verified that the Java plugin is enabled. I have tried clearing Java cache via the control panel - no luck.

I realise that Apple has blocked Java according to this article: http://appleinsider.com/articles/13/01/31/apple-again-blocks-latest-version-of-java-through-os-x-anti-malware-system. I have been able to get Java to work with Safari (this doesn't help for Firefox) by editing the file /System/Library/CoreServices/CoreTypes.bundle/Contents/Resources/XProtect.meta.plist, but that is only a temporary solution, as it shouldn't be necessary to do this edit.

Version details: Mac OS X 10.8.2 Firefox 18.0.1 Java version 7 update 11

Since two weeks my Firefox just keeps crashing. Sometimes during loading an website sometimes even if I did not do anything for several minutes. It started with version 20.0.0 and continues with 20.0.1. Disabling all extensions and plugins did not help. The crashes still occur in safe mode. Resetting Firefox did not help. Reinstalling neither. I scanned my computer with two different antivirus programs. All other applications work fine and I'm working the whole day on my computer in lots of different programs... It would be great if you can tell me more about the reason so I can use my favorite browser again, thank you!

Realplayer download feature (cursor over a youtube video, "download this video" pops up) has recently quit working for me (I've been using it for months). I've searched knowledge bases and forums extensively and tried all the suggestions., such as rolling back from Flash Player 11.5 to 10.3 (no luck), disabling/enabling RealPlayer Download plugin in Firefox (no luck), etc. The one suggestion I'd like to try but can't is going into RealPlayer preferences and enabling/disabling the "Download and Record" function. I can't because all I have in my preferences is "Recording" and the options have nothing to do with downloading. None of the RealNetworks/RealPlayer support sites are helpful at all...

However, the download feature works just fine in Internet Explorer

My Firefox keeps crashing. I've uninstalled it, reinstalled it, run it in safe mode, and nothing seems to prevent the crashing. I completely deleted all of the old Firefox files before reinstalling it, but even the fresh clean version keeps crashing. The crashes happen almost immediately. I open the browser, try to load a site, and the browser crashes within a few seconds.

I have a dell inspirion mini 10, and i just recently got all the settings rebooted and reinstalled xp. All i have right now is internet explorer, and the first thing i did on the internet was attempt to install firefox. The first two times my modem fell off, so im not sure if that has anything to do with the problem. Bu t now everytime i try to install firefox it stops at 99%, and doesnt finish. Ive had the same problem with downloading adobe flash player and ccleaner, but i was successful in downloading vlc media player through ninite to test things out, and and old, archive version of adobe flash player. Practically nothing is on this comp, so i dont think theres a problem with sercurity firewall or not, and im afraid it just might be the computer is on its way out, please help.

Ever since I upgraded to Firefox 21, Firefox stopped asking me what to do with MP3 or video files. The default action now is to play them in Firefox. I've previously set Firefox to ask what to do with these files. When I go to Applications settings, the setting I made is still there but gets ignored.

I know that I could set media.windows-media-foundation.enabled to false to disable playback for these type of files completely. That's not what I want. I want to be able to play these files in HTML5 audio and video tags.
