Support Forum

There is a lot of discussion on https://bugzilla.mozilla.org/show_bug.cgi?id=812695 about the right workaround or how to apply it. I'm starting this forum thread to move the discussion.

From the bug the current workarounds are:

• in about:config set gfx.direct2d.disabled to true
• in about:config set gfx.content.azure.backends to cairo instead of direct2D
• Uninstall IE10 and update KB2670838

My Firefox keeps crashing. I've uninstalled it, reinstalled it, run it in safe mode, and nothing seems to prevent the crashing. I completely deleted all of the old Firefox files before reinstalling it, but even the fresh clean version keeps crashing. The crashes happen almost immediately. I open the browser, try to load a site, and the browser crashes within a few seconds.

Realplayer download feature (cursor over a youtube video, "download this video" pops up) has recently quit working for me (I've been using it for months). I've searched knowledge bases and forums extensively and tried all the suggestions., such as rolling back from Flash Player 11.5 to 10.3 (no luck), disabling/enabling RealPlayer Download plugin in Firefox (no luck), etc. The one suggestion I'd like to try but can't is going into RealPlayer preferences and enabling/disabling the "Download and Record" function. I can't because all I have in my preferences is "Recording" and the options have nothing to do with downloading. None of the RealNetworks/RealPlayer support sites are helpful at all...

However, the download feature works just fine in Internet Explorer

3 days ago I was trying to watch videos on youtube and i kept getting adobe flash player crash error. i went ahead and updated to firefox 20.0.1 and i updated to flash player 11.7. still getting the error. Ive clean installed both since. I've reverted to older versions even the 10.3 listed on Firefox Troubleshooting guide. Nothing seems to work. I cannot watch any video period on any website that i've tried. Ive ran Malwarebytes and virus scans both with latest definitions and all is clean. Now firefox just crashed as i was writing this. weird. some assistance would be appreciated. Thanks

Since two weeks my Firefox just keeps crashing. Sometimes during loading an website sometimes even if I did not do anything for several minutes. It started with version 20.0.0 and continues with 20.0.1. Disabling all extensions and plugins did not help. The crashes still occur in safe mode. Resetting Firefox did not help. Reinstalling neither. I scanned my computer with two different antivirus programs. All other applications work fine and I'm working the whole day on my computer in lots of different programs... It would be great if you can tell me more about the reason so I can use my favorite browser again, thank you!

Ever since I upgraded to Firefox 21, Firefox stopped asking me what to do with MP3 or video files. The default action now is to play them in Firefox. I've previously set Firefox to ask what to do with these files. When I go to Applications settings, the setting I made is still there but gets ignored.

I know that I could set media.windows-media-foundation.enabled to false to disable playback for these type of files completely. That's not what I want. I want to be able to play these files in HTML5 audio and video tags.

facebook was working fine now suddenly I get this stuff about them not using a trusted security certificate and firefox won't open the site AT ALL! :(

SEE BELOW

This Connection is Untrusted

         You have asked Firefox to connect

securely to www.facebook.com, but we can't confirm that your connection is secure.

         Normally, when you try to connect securely,

sites will present trusted identification to prove that you are going to the right place. However, this site's identity can't be verified.

         What Should I Do?
         
           If you usually connect to

this site without problems, this error could mean that someone is trying to impersonate the site, and you shouldn't continue.

       www.facebook.com uses an invalid security certificate.

The certificate is not trusted because no issuer chain was provided. The certificate is only valid for FF

(Error code: sec_error_unknown_issuer)

I have a dell inspirion mini 10, and i just recently got all the settings rebooted and reinstalled xp. All i have right now is internet explorer, and the first thing i did on the internet was attempt to install firefox. The first two times my modem fell off, so im not sure if that has anything to do with the problem. Bu t now everytime i try to install firefox it stops at 99%, and doesnt finish. Ive had the same problem with downloading adobe flash player and ccleaner, but i was successful in downloading vlc media player through ninite to test things out, and and old, archive version of adobe flash player. Practically nothing is on this comp, so i dont think theres a problem with sercurity firewall or not, and im afraid it just might be the computer is on its way out, please help.

The Issue.... Coupons.com plugin disapeared after upgrading FF to v21 (from FF Help Menu>About) I then was prompted to install the plugin when i went to print a coupon from coupons.com... the installation shows it succeeds with no issues, however the plugin is still not showing in the plugin list, and of course coupons don't print (You are prompted by coupons.com to download the plugin...over and over again)

How it happened..... I almost never reboot the PC. Before today everything was working fine. I didn't reboot PC, but decided to upgrade FF to latest version (previous was 20.something)... because i was getting a really long (and context insensitive menu when right clicking anything).

The upgrade appeared to run flawlessly, but then the issue with coupons.com became apparent, and upon a quick look in about:plugins, i noticed the coupon.com (coupon printer) plugin is no longer there....

I closed all browsers, uninstalled the Coupons.com plugin (from Add/Remove programs), and verified that Internet Explorer can't print coupons anymore from coupons.com. Then i reinstalled the plugin (from coupons.com) and Internet Explorer was once again able to print coupons. This means the plugin is being installed on the PC, and while Internet Explorer works, Firefox doesn't (since this version 21)

More and more frequently, when I open a web page, the text is distorted. If I place another window over the text or highlight it, the distortion disappears. If I scroll the web page, the distortion scrolls with the text.

I've attached an image. Does anyone know what this is or how I can fix it?

Most of the time FF 21 crashes directly after starting it.

- No matter if I restore tabs/session or not.

- If the program opens and I fill in an address in the address bar FF crashes as soon as I click "enter"

- FF crashes immediately when I click on a link (website or download)

- Deactivating Add-Ons didn't help

- Safe Mode crashes the same way

- Creating a new profile didn't help

- Using the "Reset" in "Troubleshooting" didn't do the trick

- Completely removing Adobe Flash and reinstalling latest version: no improvement

- Disabling HW acceleration: no change of problems

If I downgrade to 20.0.1 it works perfectly as it did in the last weeks. After the upgrade to 21 same problems. Downgrade again: all is working.

This applies to my desktop PC. On my notebook the upgrade from 20.0.1 to 21 worked flawlessly - and I am using the same add-ons on both machines. But as disbaling add-ons doesn't help this seems not to be the right direction anyway.

I've sent about 2 dozens of crash reports now using the integrated assistent. Hope this helps narrowing down the issue.

I have the same problem as https://support.mozilla.org/en-US/questions/881844 but with fx 21.

Firefox 21 on Ubuntu 13.04 stops loading pages after a while, ranging from less than an hour to a day, of regular browsing. It gets stuck on "looked up whatever.com" or "connecting to..." message. Restarting the browser makes it work for another period.

Changing network.http.max-connections did not help, clearing various history items (cookies, cache, ..., or everything except saved passwords) did not help.

I now disabled ipv6 https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can?#w_ipv6 and prefetching but the fact that the problem occurs after several hours makes it hard to test.

Ever since February (some kind of update happened), Firefox has basically died on my computer. I open it and only for a few moments does it work with any kind of speed, then it literally dies to a snails pace. It takes minutes even to scroll a screen or open a menu screen. And that's just being on the Mozilla site. Forget about trying to open any other significant websites. I have tried everything from reinstalling, resetting and disability plug-ins. I will say that the Firefox Icon at the bottom of my screen shows a security shield on it, which didn't use to be there. I really need help. I've been forced to use Chrome, which did work fine, but I can't stand it. SAVE ME PLEASE!!!!

So, after updating to Adobe Flash 11.7...I can no longer watch a single video anywhere on the web without the sound randomly cutting out. Flash does not crash, it just stops playing the sound and keeps playing the video. I can rewind the video to a time before it cut out but then it cuts out again RIGHT as I rewind to a new point in the video. Where as before in the location I rewound to, it did not have the sound cut out before when I first watched up to and past that point. I have no idea what has caused this (except or maybe Adobe screwed something up).

Does anyone else have this issue? And what have you done to solve it (if you have)? Also, if this a Firefox only issue? Or is it everyone Web browser?

Thanks for any help given.

For the last few days my Firefox does not display the downloads window. I have tried to follow the suggestion set out in Firefox Help ie Tools --> Options --> General

But my General Tab doesn't show under Downloads the option to check the box "Show the Downloads window when downloading a file". Under Downloads, the only option shows "save files to Downloads" and "Always ask me where to save files".

Any suggestions on how I can get to --> Downloads the option to check the box "Show the Downloads window when downloading a file".

Thank you in anticipation

I have problem loading Java related websites after an upgrade to the latest version of Firefox 17.0

Some pages, keep asking me to enable "Javascript". Under preferences, "Enabled Javascript" is already being checked, yet the websites still will not load.

Java is already updated.

I do not have this issues before the upgrade, and all along it is working fine.

Many familiar sites are giving me an error relating to certificates. See message below:

"This Connection is Untrusted

         You have asked Firefox to connect

The same sites are still working perfectly on an older computer without these issues. They also work in other browsers, but Firefox is my default.

Hello everyone, This is driving me crazy! I've been trying to fix this a couple of times but no luck.

I'm trying to watch youtube videos on firefox and so whenever i try to enable flash player it just freezes my firefox...

I've uninstalled flash, installed latest/oldest, uninstalled firefox, restarted my comp, deleted the directory, disabled hardware acceleration, cleared cache and no luck...

When I use html 5 it doesn't freeze though I don't want to use it because it doesn't have 240p quality option.

Sometimes when flash player is enabled it doesn't freeze instantly only when i enable html5, play a video, close it then enable flash player addon then load the video which doesn't freeze until 3 mintues then freezes completely.

Ideas? Thank you.
