Firefox Support Forum

I just updated to the latest version of Firefox (18.0.1) and I find that I can no longer navigate to fully half of the sites I used to, such as Gmail and Facebook. Most of the sites I go to now don't even look right, they just display text, no UI. Even as I type this up, there's only text. I tried to use Firefox's own tool to find which plugins I had installed, and it gave me the same "This connection is untrusted" message. Most of the sites I got to allow me to make an exception, but Gmail doesn't, nor does the Firefox plugin page. I've used Firefox for years but this is the first time I've ever had an issue like this.

I have firefox 18.0.1 on windows OS. And there is a problem with TSL 1.2. In about:config this is all what I have regarding TLS:

security.enable_tls;true security.enable_tls_session_tickets;true services.sync.prefs.sync.security.enable_tls;true

There is no security.tls.version.max.

In Options-->Advanced-->Encryption there is only "Use TLS 1.0"

How to enable TLS 1.2?

2 Feb 2013 Concerns: Firefox 18.0.1 often freezes, at random times, since about 31 Jan 2013 I am using Mozilla Firefox 18.0.1, Windows Vista, PC, Desktop. My Mozilla Firefox freezes since about 31 Jan 2013 at random times quite often, when I do see TV or videos, also with YouTube videos. It freezes especially when I do start TV or a Video, sometimes also it freezes when the video is running for some time. I do use Firefox mostly only for TV and videos, so else I do not see. Some days earlier (26 January 2013), I had installed the upgrade of the new Norton Internet Security 2013. The two Norton add-ons on for Firefox, I have both deactivated. I can get out of the freezing, when I do click to end the Internet connection. After I have waited for about 5 seconds, the Mozilla Firefox browser can be moved again with the cursor. After I click to close the Firefox, and wait for about 5 seconds, the freezing also does end. I did do two Windows restores, one to 1 week ago and the next to 2 weeks ago. After the restore, when I started Mozilla Firefox, it was at first Firefox 17. But to my very bad luck, Firefox started immediately to update to Firefox 18.0.1 I had seen this updating on Help – About Firefox. There were good times, when people could choose themselves which version of Firefox they wanted. After the restore, I had also downloaded the latest Adobe Flashplayer version (about version 11.5), but the freezes have remained the same. Is there a possility to prevent the automatic update of Firefox? So that I could choose which version of Firefox, I do want. When there is a serious bug in Firefox, I could nevertheless use Firefox instead of changing to the Internet Explorer. I know I myself am responsible to prevent hackers from entering my computer. I have read that 80% of users in Germany do not have any Internet Security against hackers at all. My Internet Explorer until now does not freeze.

Java works in Internet Explorer but doesn't work in FireFox.

My installed Java-related programs are: Java 7 Update 11 Java 7 Update 11 (64-bit) Java SE Development Kit 7 Update 11 Java SE Development Kit 7 Update 11 (64-bit)

I don't have JavaFX or anything else. I need both kits for Eclipse and other things.

Starting early January 2013 in Firefox, YouTube videos are loaded as blank black screens for the first five seconds. At the 0:06 mark, videos start playing normally. This is not an issue in Chrome or IE. Tested with all plug-ins and add-ons disabled (except Flash player). Plug-ins/add-ons updated. Tried re-installing Firefox with no solution. Help? Thanks!

My MacBook hard drive (HDD) died. Now I have new HDD. Now my old hard drive is like external HDD. And I'm trying save all files from old HDD to my new HDD. How can I import bookmarks into my new hard drive? Where can I find my old bookmarks on my old HDD?

I have the latest versions of both Firefox and Norton Internet Security, have rebooted many times and still no Norton toolbar. The add-ons screen does not list the 2013.2.3.1 version, only the previous version that is disabled. Is there a way to force this update?

thanks kilgore

I think this began when the auto-update to 22 occurred. I run Firefox on a PC with Windows 7 AND a Macbook Pro running 10.8.3 and the same error is occurring on both machines. At an increasing rate, as if some cache is filling up, I get errors that say a script is slow or not responding and identifying it as various javascripts. Eventually--and always if I write a long email, it's like working in marmalade and I knock everything down, reset and try again. I use Icloud as my primary email program on both machines.

I have deleted java, installed new 32 and 64 bit java and even gone to 64-bit Waterfox but nothing has solved the problem. I've installed, disabled and re-installed every damn extension.

Now, when 18 first went in, I lost the ability to see any javascript based emails -- e.g. from Wordpress--unless I forwarded them to myself. This suddenly fixed itself so I imagine people are trying to catch up with bugs caused by the update but this slow javascript thing is NOT getting any better.

Hi

Firefox 18.1.0 18.0.1 crashes constantly whenever I close a tab.

This is getting very frustrating I have used FF for several years now and would hate to have to find another browser. Any suggestions please.

_{Edited Firefox version number from 18.1.0 to 18.0.1}

When I'm on Tumblr, scrolling through my dashboard, I noticed that after a while it gets very slow. The reason why, is that everytime I scroll down a bit or press the 'j'-key (to go to the next post), firefox/tumblr already loads a next page of my dashboard.

So by the time I go down by 20 posts, I already got 20 pages loaded. And when I finaly reach the end of all the new stuff since the last time I checked Tumblr, Firefox is very slow because of the (probably) thousands of posts that it has loaded. It should load the next page when I'm (almost) at the end of the last page.

when I look at my scrollbar to the right, it also shows a very small bar that is only at about 20% of the track. As shown in this image (this is only after pressing the 'J'-key 20 times): http://i.imgur.com/4vkkpEG.png

I'm using Waterfox (a version of firefox specially made for 64bit systems) but this also happens with the normal firefox. It doesn't happen in google chrome or internet explorer. I have used the tumblr savior addon before this started happening but I've disabled and uninstalled that a while ago and I also made a new profile to see if that fixes it (it didn't).

The Add-Ons manager says: Adobe Acrobat - Create PDF 1 (disabled)

All that happens now is that, when I click on a PDF Google result, a page with the correct URL opens, but no file is downloaded. If I use Quick View, however, I go to the PDF on the site. If I click Download Original, I just get the blank page again. Any ideas?

in the left margin of the yahoo.com home page there is a list of default 'sites' chosen by yahoo. just to the upper right of this sites list, there is supposed to be a 'gear' icon. this icon when clicked allows the user to alter the sites list by adding or removing entries in the list. since the gear icon is not visible in my ff browser, i cannot make changes to the site list.

when i use internet explorer to access the yahoo.com page, the gear icon is present in its correct location and works as designed.

I added an extra toolbar to FF a long time ago... I added absolutely loads of button icons to it for all sorts of functions. Largely out of the Customise set. Now the whole toolbar has disappeared. It is not there to re-tick in the Toolbars options. The Firefox help and Community Support items on related problems don't cover this. I can create a new toolbar of course but it would take hours to re-find and place all those icons. And I really don't want to Reset Firefox until I know I definitely can't recover the lost toolbar, for the same reason.

Before upgrading from 18.0 to 18.0.1, the Firefox theme listed under [Tools][Add-ons][Appearance] was called "Default 18.0" and was better than the default in 18.0.1. I want to restore the plain old default 18.0 theme, but I could not find it in the humongous collection of available themes. I do not want a fancy theme, just the old default for 18.0.

I just updated 18.0.1 last night and the problems began immediately. Even this site I had to allow as an exception then when it loaded it has no colors, no menus, etc. This is happening for facebook, parts of amazon, etc. I get "This Connection is Untrusted" when I try to load gmail, log in to Amazon, trying to load this support page, etc. However I have no problem with google.com, wiki, and other random websites. I need this fixed as soon as possible, I have a deadline for my job and can't open my email to send files.

I am relativity tech savvy, but reading through the forum about firewalls, and such did not help me. I'm completely lost, panicking and three seconds away from just completely wiping my computer.

I want to upgrade to latest version but -Help/About Firefox- window does not show "upgrade" as in the instructions. I cannot find an "upgrade" function anywhere else. How do I upgrade? The version I have is -18.0.1- it came with this used computer.

I believe this computer was hacked. Word started doing very strange things. We wiped the hard drive and reloaded everything as it was originally when I bought it. I am now getting hacked online.

They originally got into one of my credit cards last fall. That is when this all started. They got my AOL email address. They also got the credit card current balance, minimum payment, due date and then even the payment amount. They got into my Barnes & Noble account and now checkout does not work. Now I believe they have gotten into my AOL account - one thing after another has started going wrong. I cannot change that AOL user id/email address since it is the master and I would lose about 15 years of "stuff".

The folks that sold me this computer told me to use a free version of an antivirus. I am very unhappy with it. I never had ANY trouble when I used TrendMicro's expense products. Those folks also told me to use Firefox, since AOL uses Internet Explorer - which I already knew is like Swiss cheese.

Now, I cannot seem to get an upgrade of Firefox. Is this also a hack?

Please help any way you can. Thank you for your time.

Rebuilt my website in Serif WebPlus X6.
Using Google Chrome or Internet Explorer the site is displayed correctly as is the source code.
In Firefox 18.0.1 Code is being read wrongly. Cleared Cache and fault still there. Checked in Wifes laptop – still the same fault on her Firefox and okay on Chrome and IE.

</span></p>    
But firefox is showing -      span class="Body-C-C9">“Why won’t the doctors listen”?</span></p>

There are further similar faults throughout the website.
Why is Firefox not reading the code correctly?
Please help.

They just stopped appearing on July 19. No explanation. I tried switching browsers and it worked for awhile in Safari but not any more. I sent a note to twitter. I tried refreshing the screen. Nothing.

Even with Mackeeper my Mac runs slower and slower. When I go to Firefox, three AOL mail logos pop up. This can't be right. Does it slow down the machine? Help!

What is all of this?

Hello, I've been using Firefox since a long time but as I remember it only appens since I've updated Flash to 11.3 ( I currently have 11.5.502.146 installed. So when I go on youtube for example to see some videos it works find but when I pause the video, wait a few seconds and then want to continue it the sound isn't there anymore.

I wonder why it only happens when I do such things. ( I checked the sound level from Windows but it wasn't muted . )

EDIT : I don't know if it helps or not but Flash works fine in Opera 12.11 x64 .
