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?

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 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.

Recently I was forced to restart Firefox after a series of unexplained crashes, which I do not mind at all. I decided to create a new persona for Firefox in order to start again, but ran into an unexpected problem. Although my header and footer were their respective requested sizes, upon using the persona I could only see the top right-hand third of the image. I attempted scaling down my images in Photoshop and resubmitting them, but anything smaller than the requested size is not accepted.

Thank you for your time, and I will be eagerly awaiting a reply.

why do web pages in firefox keep resetting little blue circle keeps spinning and pages loading slowly have scanned for malware computer clean history and all caches cleaned help dont know what else to try dont have that many add ons just the ones really needed turned others off dont really want to reset firefox have to reset all my settings i have a window 7 starter hdmi lt40 intel adam n2600 intel graphics media accelerator 320 gb hdd 1 gb ddr3 memory gateway netbook firefox21

I've been getting two "this script is running slow" messages a lot lately in Firefox 20.0.1 and Firefox 21. It mostly happens when I'm accessing webmail from Optimum or when I'm at www.bufferapp.com but it's not limited to those two web sites.

The one script it says is running slow is https://ajax.googleapis.com/ajax/libs/jquery/1.8/jquery.min.js:2 and the other is https://d389zggrogs7qo.cloudfront.net/js/app.min.275befaba77ad321bc495dd90bfd558b.js:75

the only solution I find in the knowledge base for the former is for Macs, not Windows 7 machines. I can't find anything for the latter error. It happens A LOT. Any suggestions? I've updated Flash and Shockwave. No change

I recently downloaded and then deleted the Capture & Print add-on. The S (screen capture), W (window capture), and R (region capture) icons, however, are still showing up in the top, right hand corner of my browser, right beside the minimize, restore, and exit icons. The S, W, and R icons are in the way when I try to close tabs or open new ones (up at the top of my screen). I have restarted my computer several times, but these icons continue to show up. Every now and again they go away, but then they come back.

I've tried going to the Toolbar Layout area, but when I open that, the icons disappear, and I'm not able to drag them away and delete them.

I want my Menu bar on top, My address bar below that, my tabs below that, and my bookmark bar below that on the very bottom. I can go in about:config and manually toggle the tabs to be on bottom, however that puts it below all my bookmark buttons! As it stands, the dumbass order of my toolbars (which is really pissing me off) is menu bar, tabs, address bar, and then my bookmarks. HEEEEEEEEEEEELLLLLPPP!!!!! THIS IS FREAKIN ANNOYING!!!!!!!

firefox is deleting my download history, I truly don't want firefox to do that. in earlier versions you could hold onto those items, i need to know where my downloads go to because i choose folder.

recentaly i have faced many problems with firefox: flashing and shivering windows and sometimes if more than window is opened they start to change their places automatically. So, i decided to reset firefox. Before i do that i synchronised all my bookmarks and add-ons, as i thought, using the synchronising feature in firefox. after resetting i discovered that firefox only RESTORED bookmarks, WHY?????? i was really annoyed and upset, i love my add-ons and i want to retore them. PLEASE HELP SAVE MY ADD-ONS

(BY THE WAY, firefox works now better without problems, but i want my add-ons)

When I open up a webpage, a box slides out on the bottom from the left side. It has a black border, and I can't get rid of it. It's rather large, and covers part of the page. it happens all the time. i want it gone!

The edit box in the Twitter Compose New Tweet box sticks off the right https://pbs.twimg.com/media/BNHnQSICEAAHz_H.png:large

I am aware I am not using the latest version of Firefox. Bases on what I've read I'm not going to like the changes in the latest version and do not want to change versions until absolutely forced too.

This problem occurs in safe mode, and with multiple profiles.

I have seen some reports from other people saying they have the same problem.

I clicked on the "Check to see if your plugins are up to date" in the Plugins section in Add-ons Manager. I see a bunch of Google plugins (Picasa, Google Update, Google Talk Plugin Video Renderer) and Windows Live Photo Gallery in a section titled "Unknown Plugins". I was wondering if this is a problem on the end of the makers of these plugins (not keeping them up to date or not making them in such a way that Firefox can recognize whether or not they are) or if it is something on my end?

Also, my "Google Earth Plugin" is outdated but clicking Update Now does nothing. Does anyone know the reason for this?

It is from http://node-27.gamecolony.com/v3/ It also says "Your security settings have blocked an application from running with an insecure or expired jre.

When signing in, I receive a pop-up/Security Alert that states, "Although this page is encrypted, the information you have entered is to be sent over an unencrypted connection & could easily be read by a third party. Are you sure you want to continue sending this information." Two blocks-one labeled 'Continue' and one labeled 'Cancel'. The only choice that allows me to access by provides is 'Continue'. No info is given on what action is recommended to resolve the 'Security Alert' and I can't cancel the 'Security Alert'.

All drag-and-drop features stopped working on my FF 21.

That is, I can no longer: - Drag items to bookmarks or rearrange the bookmarks - Drag words to the search box or links to the URL box - Change the order of tabs - Rearrange items on toolbars - Move text in text boxes - etc.

Safe mode exhibits the same problems.

Please advise.
