I get this message all the time?

Could not initialize the application's security component. The most likely cause is problems with files in your application's profile directory. Please check that this directory has no read/write restrictions and your hard disk is not full or close to full. It is recommended that you exit the application and fix the problem. If you continue to use this session, you might see incorrect application behaviour when accessing security features.

The only way I have found to fix this is deleting the cert8.db file. This is happening so often that I can no longer use FF anymore. Why is this file getting corrupt? I have plenty of disk space on this machine so that is not an issue.

In the last few weeks a Warning Box comes up to tell me my Firfox has crashed and if I select the option to discover the casue this comes up. However, I still seem to be able to do everything as normal, go on line etc etc and without this warning box (giving me the option to close the programme and search online for help, Close the Programme and/or Search the cause) I was unaware of any fault or anything different from normal. - What's the Cause and Do I need to do anuything? This is the "CAUSE":-

Hi For years I successfully used the following two proxy.pacs on Windows XP Desk- and Laptops:

function FindProxyForURL(url, host) {

  if (isInNet (myIpAddress(), "172.17.0.0","255.255.0.0")) 
     return "PROXY 172.17.4.10:3128";
  else 
     return "DIRECT";

}

or

function FindProxyForURL(url, host) {

  if (isInNet (myIpAddress(), "172.17.20.0","255.255.255.0")) 
     return "PROXY 172.17.20.5:3128";
  else 
     if (isInNet (myIpAddress(), "172.17.0.0","255.255.0.0")) 
        return "PROXY 172.17.4.10:3128";
  else
     return "DIRECT";

}

..which did work well. Now surfing became extremely slow (about 20 seconds to see a site). When I fill in the IP address of the proxy in the config (instead of a proxy.pac) then firefox works fine again. It looks like the algorithm for interpreting proxy-pacs has changed; maybe for any new URL-connection the pac-file is re-interpreted?

Could somebody please help me?

Kind regards, Richard

This started happening a few weeks back and I can't get rid of the problem. Have looked at other forum entries/responses but I don't have anything suspicious (like Tuto/Sweet etc) in Add or Remove Programmes. Whenever I open Mozilla, tabs for random ads appear. I delete them and then all's fine, until the next time I open Mozilla. Not sure why it's suddenly started happening but would really appreciate your suggestions for stopping it! Many thanks

I want to embed video in my html page and use data URI to provide video source:
[video controls]
[source src="data:video/ogg;base64,[video base64 code]" /]
[/video]

This code works fine in Opera and Google Chrome, but in Firefox some of my videos are not properly loaded. Video is playing, but I can't seek in it and don't see its length.

I use Firefox 21 on Centos 6.2 and Windows 7.

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.

When I enter about:config into the adress box I get only an empty page. The about:config works normally on safe mode.

I have tried to check all boxes in the safe mode window, this did not help. I even manually disabled all add-ons and plugins, but this didn't help either.

Any ideas what to do?

i reset ff but two addons remain, fluxdvd download manager 0.5 been trying to get rid of this one for a long time and microsoft.net framework assistant 0.0.0 .

hello im trying to make my nightly in metro style, can any body help me? Ive already made it my default browser how ever that didnt make it work!

waiting for a reply, Thanks

Firefox is not hanging as I can access all the items in the menu bar and change the settings as well. it just seems to need time before it can connect to my server even though Safari is working fine. Once the page loads up in firefox it works fine after.

I have added 3 email addresses and confirmed them, yet I still get sent back to the dashboard. Infuriating.

I simply want to let Mozilla know that they need to provide an alternate browser for the iPod Touch. Or, if they have, I am having trouble finding it.

We are trying to use HTTPS client certificate based authentication to access a Java Applet in Firefox v21.0. We have followed the instructions as per the below two urls to enable JSS 4 -

http://docs.oracle.com/javase/6/docs/technotes/guides/deployment/deployment-guide/keystores.html
http://download.java.net/jdk8/docs/technotes/guides/deployment/deployment-guide/keystores.html

We are using JRE version 1.7.0_25-b16 Java HotSpot(TM) Client VM in Firefox v21 but we are getting -
security: Accessing keys and certificate in Mozilla user profile: null
security: JSS is not configured

followed by SSK handshake failure when trying to load the client certificate.

The client cert based authentication is working when using IE v8 and IE v9 with the same JRE version (JRE version 1.7.0_25-b16 Java HotSpot(TM) Client VM)

Any help to resolve this issue will be very much appreciated.

Dear developers, for some time Firefox has a plugincheck "feature". Is there any way to turn it off? This blocks contents for eg. flash videos, so I have to enable the "old" plugin for each website... I do not care if my plugins are up to date or not. I'll update them if I want to. This is a very annoying thing in the firefox :( I use this browser for many years, but as you develop this, it just getting worse and worse. Slow, eats a lots of memory, some "plugin container" slows my whole system sometime and now this plugincheck. I'm seriously thinking about changig browser if there's no way to turn it off :( Please answer ASAP (no answer, like "we are planing..." is acceptable) Thank You for answering.

When I try to open a new tab I get this: Server not found

         Firefox can't find the server at www.[r;;iåvÞyevq¾qîx»òki.com.
       
       

 Check the address for typing errors such as
   ww.example.com instead of
   www.example.com
 If you are unable to load any pages, check your computer's network
   connection.
 If your computer or network is protected by a firewall or proxy, make sure
   that Firefox is permitted to access the Web.

I can get Firefox to open, but other than that nothing works. It doesn't respond to type or the mouse. In fact, it acts like your keyboard or mouse are no longer working. Which they are.

It was working fine & then it just stopped.

I've tried uninstalling & re-installing. That didn't help, nor did going back to an older version. I even tried using Windows restore point & going back in time. Nothing has helped.

My OS is Vista.

Can anyone help me? Thanks.

When I try and open the Firefox drop down menu there is no text to explain the different options. The same thing happens when I try and right click, there is no text only blank spaces. If someone can help I would really appreciate it. I have used Firefox for a long time and I would hate to have to stop using it. I can post screenshots if needed.
