Firefox has worked perfectly well for some time on this machine (Dual core AMD Athlon with XP SP3). This morning at startup Firefox opened on my second (DVI) monitor, not on its usual VGA connected screen. I used the maximise button to shrink the window from full screen and dragged it to the correct monitor and remaximised it. It then was very slow, mouse movements happened in large increments making it difficult to point and click, switching tabs resulted in a slow vertical wipe to reveal content rather than instantaneous switching, loading websites was very slow indeed. Using task manager indicated that one CPU core was running at or near max much of the time, particularly when moving the mouse. I rebooted and also reset Firefox to no avail. However, if I move the Firefox window from the VGA monitor to the DVI one then performance/resource usage is normal. I can open other apps on the VGA monitor (eg MS Word) and they behave normally. It just seems to be Firefox that is having this problem.

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.

Hello, I have registered in addons.mozilla.org but everytime I login it displays an error "oops..". I've tried resetting my password too but this doesn't help & cleared all cookies/cache. Any other suggestion(s)?

Thanks in advance.

I have downloaded a JNLP file from http://phet.colorado.edu/en/simulations/category/physics for a physics class that I'm taking, but the file will not load or start in Firefox. Java Web Start has already been installed by the system administrator but there is no file association for, nor is there a "JNLP" file type listed in Firefox --> Tools --> Options --> Applications

How can this be fixed so that the "JNLP" file type is listed in Firefox --> Tools --> Options --> Applications?

If you can get me that far I can do the rest by making the file association to javaws.exe. Thanks.

There needs to be clarification on the Java issues. It's clear that we can disable Java in the java control panel itself and/or via the plug-in link.

However, what about the firefox options menu? Where you click Tools_Options_Content and then you can check or un-check "Enable JavaScript" -- is that safe to be checked/enabled or is that also part of the security concern w/ Java right now?

The title sums it up nicely. I bought a new laptop 2 days ago and Facebook and Twitter do not load correctly in Firefox (ANY AND ALL VERSIONS - I have been installing/uninstalling/reinstalling nonstop like a maniac). They load in every other browser just fine.

Basically what happened is I installed Firefox on the new laptop (first thing I did), loaded Facebook and Twitter for the first time, and once I closed those pages and re-opened them, they started to appear with the text flush to the left and without some images. Almost looks like a part of the CSS code is missing.

I have tried ALL of the solutions posted on these support forums. None of them are permanent

Clearing my cookies/cache IS NOT an adequate solution. It works for the first time and then I have to do it every time I close and re-open FB/Twitter. Since the entire Windows 8 O/S concept is based on the "social experience," this seems somewhat ironic. Either it's a problem with my new laptop but I doubt it, as I said before, every other browser and webpage work fine.

My conclusion is there's a problem between Firefox/Windows 8/Facebook and Twitter. If someone could just confirm or shed some insight to development problems or suggest permanent fixes, that would be greatly appreciated and save me a lot of headache. As it stands, I'm about to throw this laptop out the window. >_> I'm very much not impressed with the hassle this transition has been.

Google Chrome has always been a close second to Firefox in my eyes and it looks like I'll have to switch over, despite the fact the former does not have a customizable bookmark toolbar.

Thanks in advance.

I have NORTON INTERNET SECURITY if anyone can suggest any settings change.

I can't access a website, I keep getting a "403 forbidden" error messege? How can I bypass this and get to the website? I get this on Firefox, chrome and IE....the site had worked fine, and suddenly had this problem on all browsers. But Firefox is my chosen browser

Greetings!

My Adobe Acrobat plugin has been whining and complaining for ages, showing itself as yellow and outdated on the plugin check page, and saying that it's vulnerable. Before opening a pdf document, I reach a dark page where I have to click to activate the plugin.

Fortunately, the mozilla plugin check page is kind enough to give me a handy yellow button right next to the outdated plugin, that will let me update it. That handy yellow button leads me straight to the download page for Adobe Reader 11. I must have installed that guy hundreds of times by now, and Adobe Acrobat plugin still refuses to hear anything, and still claims to be vulnerable and outdated. I would really like to find a way to persuade Acrobat to be up to date.

Thank you for your attention.

I've followed EVERY suggested "cure" for the FAILED Cut/Copy - Paste function in FF 18.0.2 without success and am entirely considering UNINSTALLING FF and going back to IE8. There are MANY FF features I like and want to keep it but the simplest things become so frustrating ... SUCH AS: 1) Clipboard has worked ONLY SPORADICALLY no matter what I do, 2) Why is there no URL history while using PRIVATE BROWSING so I can retrace my own steps when needed by either pressing the BACKSPACE key or clicking the back arrow. Pressing the back arrow ONLY goes a certain number of steps back and then loses my origination point., 3) Why does the EMPTY CACHE button NOT clear all HISTORY. i.e., I go to a website, say Yahoo email, do my thing and sign out, then click HOME then Empty Cache and enter Yahoo email for a different email account and Yahoo recognizes my attempt and enters me into my previous email User name. Shouldn't happen, in my opinion. Any help here, WITHOUT run AV/malware detection/clean and delete registry entries since NONE OF THESE do anything positive??

I am currently using Firefox version 18.0 yet when I open Firefox, I always get this pop up message: “This version of Firefox is not supported by Norton Confidential. You will not be protected while browsing the Web. Norton Confidential cannot protect you while you use this version of Firefox. Phishing Protection requires Firefox 1.5 or later.” Do you know what is causing this? This started when I updated to Firefox 16.0.2. Am I at risk?

Hello,

In the past I saved a password for a web site. I changed the password and I had do delete the old password and since I can't save the new password for the site. The option or "remember password for sites" is not key sensitive. How can I make Mozilla to ask me again if I like to save the password for the site ?

Regards,

I'm running Firefox 18.0.1 under Windows 7, all updates current, on a Dell M6700 I7, 2.77Ghz, 8Gig ram. When I first start Firefox, it runs fine. After about 30min, it gets slow. the bookmark memu takes several seconds to draw, sites take several seconds to load/reload. This was not a problem with the same version under Windows XP using even more plugins and extensions.

If I quit and restart Firefox, it runs fast for awhile, then slows down again.

I've tried turning off most extensions and plugins and the problem does not change.

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.

I am using the downloads window. I had this problem all of a sudden it was working fine ( used to be on the BATA version) I have gone back to the standard and still have the issue. When trying to view the PDF billing statement I get a window that says windows can't recognize the program to use to open the file. Using explorer I don't have any issue at all. Ireally like firefox but this problem is driving me back to your competition. I hope you can help me. Ajbootz@cox.net

I restarted firefox from the help tab and the first time i search from the start page it works than if i close everything out and start again it does nothing, but if i search in the web address it pulls up.
