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

Since I've upgraded to Firefox 19.x, font rendering has been completely broken. Fonts are all messed up, distorted, etc...

See here: https://support.cdn.mozilla.net/media/uploads/images/2013-03-07-20-12-39-1f0313.png

I've read through many suggestions about changing options in about:config, and various other settings, but nothing seems to work.

The browser is totally useless like this.

Any help on how to fix the font issue would be greatly appreciated!

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

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!!!!

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.

Please provide some specific direction for this error message. This message happens each time I attempt to launch Firefox. If I click restore, it will load Firefox. But to do this each time is very bothersome.

Other information on this error page:

This is usually caused by a recently opened web page. You can try: Removing one or more tabs that you think may be causing the problem starting an entirely new browsing session

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.

Greetings! I've downloaded a program and here was some virus, now i alway have this page http://searchiu.com/?affil=141 as a start page and i'm afraid of my security. Can you help to remove this virus and get back my start page? Thanks you!

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?

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

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

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)

Is there any way to start Firefox for Android in private browsing mode by default ?

I have tried searching here (didn't find a solution) and also tried changing the setting in about:config but that didn't work.

It would also be nice to set FF for Android to clear private data on exit/quit.

Solutions to either problem would be greatly appreciated.

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.

After i updated to the latest flash player (11.7) I have problems with video streaming. The video plays but after a while the audio stops and the video will keep playing but will also stop after a few seconds. Is the new flash player update at fault?

Hi, Just a few hours ago, firefox has updated itself to the new version, 20.0. After restarting, it seems all working fine. But when I did right clicking to view the context menu (and copy image location), I saw a long list, with options like "Pause", "Play", "Mute" and so on.

Here is a shot: http://2imgs.com/2i/i/515c6224/79903d27bae38742936c6eea68084f43/d1af1c36e5.f.png

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.
