Firefox 19 updated and freezes

Firefox automatically updated itself to version 19, now I can open the browser but whenever I go to open a new page or click on anything the top of the browser goes grey and I cant do anything, all my icons, tabs etc are grey and cannot be clicked on. I have to use control panel to close the page. Have tried re-installing and it still does the same.

A possible cause is security software (firewall,anti-virus) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.

Firefox updated and I can't find my scrapbook.

Firefox updated and I can't find my scrapbook.

an update alone shouldn't affect the extension - are your other customizations, preferences, etc. still there? then the possibility is high that you'll just have to reinstall scrapbook from addons.mozilla.org again and your data is still available...

You can check for problems with current Flash plugin versions and try these:
*disable a possible RealPlayer Browser Record Plugin extension for Firefox and update the RealPlayer if installed
*disable protected mode in the Flash plugin (Flash 11.3+ on Windows Vista and later)
*disable hardware acceleration in the Flash plugin

Firefox lags and freezes several times in an hour - How to fix?

I've read up on the forums and nothing seems to be describing what I'm experiencing with Firefox.
The last 3-4 days I've had several instances where Firefox lags or completely freezes up when switching between tabs. It will still somewhat work but it's ridiculously slow.
For example, it WILL eventually go to that tab, but it will take a minute, and then nothing on the page will work for a minute, so on and so on. Sometimes a black screen will appear where the text should be. Sometimes it stays black, sometimes the page eventually loads. It was only one website so I thought maybe that page was having issues until today when it started happening on several other websites.
It's happening quite often and it's driving me crazy. I only had an error message once, early on when this started. Since then it just seems to lag and freeze, lag and freeze, over and over without giving me an error message until I get fed up and close out of it. Upon start up again, it works fine for a bit.
I don't use any toolbars. I updated Windows and my drivers. Computer has been restarted several times since this started.
I'd appreciate any suggestions!

Hello EMA1, try to run [https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode firefox in safe mode], works ?
If firefox in safe mode has the same behavior then, try to boot your win 8 computer in [http://support.microsoft.com/kb/2809468/en-us Windows Safe Mode with network support] and check firefox again. Any luck ?
thank you

Laptop shut down during firefox update and now will not start up - did a uninstall and reinstall and still will not start up

firefox was installing an update and i accidently hit the power button and so it shut down in the middle of the update. after i started my computer again, firefox would not start up. i tried to download it hoping the update would complete but it still would not start up when i clicked on the icon. so i tried to delete it and it would not delete said it was open, so i shut down and restarted the computer. then it deleted using the control panel remove program option. after that i logged onto IE to mozilla.org and downloaded it, afterward it still would not open up or connect to the internet.

Hi meekprm-
It sounds like you've tried to do the right thing- by uninstalling and then reinstalling. I'm hoping that you can look over the steps I usually suggest and see if there is anything different that may help you get a fresh version of Firefox installed.
* Get the latest version: http://www.mozilla.org/en-US/firefox/new/
* Uninstall your current Firefox version.
* Do not remove personal data when you uninstall the current version.
* Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.
* It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
* Your bookmarks and other profile data are stored elsewhere in the Firefox Profile Folder and won't be affected by a reinstall, but make sure that you do not select to remove personal data if you uninstall Firefox.

Hope that helps!

How do I uninstall Firefox update and make my Norton toolbar work again?

Norton has all of my passwords saved in the toolbar, and now I can access any of them! How do I uninstall Firefox 17 and get back to 16 so that my toolbar works again? (I already ran the Norton Live Update and it did not fix the problem.)

I already ran the Norton Live update and restarted with no success. I have Norton Security Suite, not Norton 360. The only way I have been able to make this work in the past is to stay 2 or 3 versions behind on Firefox.

I just installed a minor Firefox update and all my previous tabs are gone. How do I get them back?

I installed a Yahoo suggested Firefox update. I had approximately 10 tabs open prior to the update now they have disappeared. I need to get them back.
Thank you

Yesterday morning when I logged on Firefox updated and then started. Since that update everytime I log onto my G-Mail account Firefox crashes

This event only started yesterday morning after an automatic update by Firefox. It has never happened before. Each time I open G-Mail Firefox crashes. I have downloaded Firefox twice since but it still happens I thought about removing Firefox altogether and downloading it again, but then I would lose all my bookmarks I suppose. I,m not an expert with computers. Any help please

Ran firefox update and now firefox does not run correctly.

I ran the latest firefox update 9Firefox Setup Stub 33.0). Now when I start firefox the browser opens and inside of it is black. I cannot see anything to use the browser. I have uninstalled and reinstalled with no luck. I have also restarted my computer. I have taken a screen shot of what it looks like.

Currently in version 33, Firefox has implemented a new, faster way of loading webpages. This new feature is called OMTC. However, there are still some tweaks Mozilla developers are making to this.
There is a known issue that Mozilla works on very hard to fix: if you are experiencing black webpages on some sites, here's what you can do to avoid the problem in the meantime:
If Firefox is open, you can restart in Firefox Safe Mode from the Help menu:
* Click the menu button [[Image:New Fx Menu]], click Help [[Image:Help-29]] and select ''Restart with Add-ons Disabled''.
If Firefox is not running, you can start Firefox in Safe Mode as follows:
* On Windows: Hold the '''Shift''' key when you open the Firefox desktop or Start menu shortcut.
When the Firefox Safe Mode window appears, select "Start in Safe Mode". 
[[Image:Safe Mode Fx 15 - Win]]
To disable Hardware Acceleration
* Click the menu button [[Image:New Fx Menu]] and select ''Options''.
* In the Firefox Options (or Preferences) window, click the ''Advanced'' tab, then select ''General''.
* In the settings list, you should find the ''Use hardware acceleration when available'' checkbox. Uncheck this checkbox.
Now, exit Firefox, wait a few seconds, and then start it normally.
Please let us know if this solves the problem. Engineering is also gathering more information about the issue would request that you fill out [http://www.surveygizmo.com/s3/1851506/1c87a6cf309a this survey]
I should also mention that other users with this problem had an embedded intel hd graphics card with an old driver present. Until Mozilla comes up with a fix, if you want Hardware Acceleration in Firefox, you can try to update your driver through the appropriate link below to see if that helps:

I have downloaded a fake firefox update and actually installed it on my netbook. what should i do? im now currently running nod32 virus scan and antimalware on my netbook

while i was browsing photos on google, another page just came up that said i have to update firefox and my flash player for security reasons and then a box just popped out and i clicked save file. After i installed it, i came back to the download page and i became suspicious because it has no mozilla.com in its address, it was http://setupfirefox.co.cc/
i researched on it in the web and i realized that i have just downloaded a fake firefox update which probably has a virus on it.
well, my anti malware scanner has detected 2 trojan horses and i removed it and restarted my netbook but i don't know what damages has been done by it..i dont even know if all traces of it has been removed..

I understand .. .. I know i am ending the process .. I have the symantec corporate edition for my anti virus .. and i have detected some of them with it .. but i believe I am going to have to run the scan in safe mode .. I could not follow your path outlined to the executable file .. I went into my C actually on mine its h windows folder and could not find it .. .. to be cont..

Downloaded Firefox update and now will not open.

For months I was prompted to download the update. I finally
did so this morning. After the reboot, I went to Firefox
with no problem, then closed the program. Later I clicked the
Icon to go back in, and it would not reload. The activity bar
and task manager icon showed the usual start-up activity, but
stopped with no Firefox loaded. Many unsuccessful attempts
since.

Do a clean (re)install:
* Download a fresh Firefox copy from http://www.mozilla.com/firefox/all.html and save the file to the desktop.
* Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
* Don't remove personal data when uninstalling.
* It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.

Firefox won't start on my Mac anymore. Turned Mac off, restarted, Firefox updated, and that was that.

I restarted my Mac this morning - when it restarted Firefox did an update and will no longer open. What can I do?

Same issue - however firefox will open but I can not click on only of my tool bar shortcuts - the writing on the google age is greyed out so I can not click on anything. Still no resolution? I have deleted the folders and re-installed - it will open and then locks and it will not work????

A site that I use regularly has buttons that I can use to navigate - but 1 has disappeared since the last FireFox update - and I can't use it anymore.

For 2 years I've been using a website that I order my products through. One of the buttons is my '''account''', the other is the '''catalogue '''(many others besides those - but those are the ones I use frequently).
After the last FireFox update (3.6.15) - suddenly the "'''catalogue'''" button disappeared. I thought it was a problem with the company site, but when they accessed my account (using an older version of FireFox) - the catalogue button showed up.
I've tried clearing my cache and restarting firefox - multiple times. No dice. Can't get it to come back.
I have screenshots to show the problem - with my computer and with my suppliers computer.
