I've tried resetting things, I told firefox to forget all my stuff when I deleted it and reinstalled it and this thing still isn't gone. I'm not a technical person and I don't really understand any of it.

I go to YouTube to play a video and it does not work, there is just a black space where the video would be, but Internet Explore will play the video, i really like FireFox, but i need for this to work and be dependable if not im gonna have to switch back to IE

i also tried this on another computer and had the same problem with Firefox

Updated to 3.6.15 and all of a sudden You Tube stop working. Sound still there but no video is showing. Only black screen.

Other browser do work and sites like Metacafe and videos embedded in other places. Adobe flash is updated to latest 10.2.152.32.

Can someone help?

Using V9 I encountered unpredictable BSOD events with message "A problem has been detected & windows has been shut down to prevent damage to your computer. etc (recommended checks)" No BIOS tuning; Memory integrity OK; no disk errors; no malware problems; no other software updates. Using XP Pro. Problem disappeared on reverting to Firefox V3.6.15; However now have lost FireFTP compatable with V3.6.15. One other observation may be relevant - upgrade to V3.6.25 failed to restart (The update could not be installed. Please make sure there are no other copies of Firefox running on your computer, and then restart Firefox to try again.) Task manager showed that no copies were running so couldn'y install update to V3.6.25. Upgrades have previously been OK.

I do web development. I was working on a site with a self-signed certificate and therefore had to create an exception in Firefox to access the site using https. Due to unrelated problems on the server, I deleted the account and then recreated it. I also had to create a new self-signed certificate. Now Firefox returns the message Error code: sec_error_reused_issuer_and_serial. I deleted the original exception from Firefox but it still returns the error. I tried to explicitly create a new exception but that returned the error, too. Note I do not have this problem with other computers on the same network and the problem does occur if I move the offending computer to another network. i.e., the problem is associated with the computer, not the network or router.

I tried uninstalling Firefox and then downloading it again. This just started happening about 3 weeks ago - fine before that.On Kijiji I can see pictures on the beginning page but when I go to the ads - say pet services - the photos do not load.

Hi There,

I have some problems with embedding from flash based content because firefox does not show the embedded content.

Last week and the time before everything went fine but now the Flash based player of Soundcloud doesn't work anymore.

I've tried to embed my soundcloudplayers via div tag on my nobleprofile, full code:

<div>
<object width="390" height="220" type="application/ x-shockwave-flash" data="http://player.soundcloud.com/player.swf?url=http%3A%2F%2Fsoundcloud.com%2Fmanuel-turobin%2Fsets%2Fmanuel-turobin-fancy-a-swift-one-before-the-show&amp;show_comments=true&amp;auto_play=false&amp;show_playcount=true&amp;show_artwork=true&amp;color=c0ff00">
<param name="movie" value="http://player.soundcloud.com/player.swf?url=http%3A%2F%2Fsoundcloud.com%2Fmanuel-turobin%2Fsets%2Fmanuel-turobin-fancy-a-swift-one-before-the-show&amp;show_comments=true&amp;auto_play=false&amp;show_playcount=true&amp;show_artwork=true&amp;color=c0ff00" />
<param name="wmode" value="transparent" />
<param name="allowFullScreen" value="true" />
<param name="allowscriptaccess" value="always" />
</object>
</div>

If I use the "data" URL I can see the player but I dont know why there are problems for a week with that embedding?!

Thanks for any help!

Even thought Firefox is my favorite browser, I'm afraid I"m going to have to give up on it:

• Gmail in Firefox won't load the standard view - only loads basic html. I don't have a slow connection. It loads fine in Chrome Gmail.

• I have Google Phone and the Voice & Video Chat plug-in. I've downloaded them with Chrome and Firefox both. It doesn't show up in Gmail with Firefox, but it shows up if I use Chrome.

• I can't view Yahoo Mail in Firefox. I tried emptying the cache. I tried allowing more memory for the cache. Clearing cookies, etc. It loads the inbox, etc. but when I try to open the mail, it's blank. Now that I've upgraded to 3.6.15, it doesn't load anything at all. It just says "Hello, Username" but the page is blank.

I have some old Java Console programs (6.0.20 6.0.21 6.0.22) that still reside in my Add-Ons box. I have not been able to get them to delete or clear out.

I may have to uninstall Firefox and lose all my settings in order to get the Add-Ons box to drop those old entries. At least, I suppose that would work.

My question is: Is there a way to clear out the Add-Ons box without having to uninstall Firefox?

Window xp high speed internet connection running firefox 3.6.15. shockwave flash is up to date 10.2.152.32

when on youtube, the video does not play. just a black screen, though the progress bar at the bottom seems to duplicate itself. I DO GET AUDIO. I do not seem to be having this problem on other websites.

doesn't crash, don't see any error messages.

I'm running windows 7 32-bit with up to date Firefox and Adobe Flash player but it crashes every time I try to watch a video. I've done the troubleshooting, reinstalled flash, reinstalled firefox and so on. The flash player works in Chrome and Explorer. What can I do to fix this?

So I tried to watch a video on YouTube, yet Firefox just shows a black box. Neither the video nor the audio will play. It doesn't crash my browser or bring up any errors, which leads me to believe that it is not a Flash Player problem.

I opened Google Chrome and tried, and it plays YouTube videos with no problems.

I restarted my computer, yet it still does not work.

Any assistance is very much so appreciated.

This started happening after I upgraded to 3.6.15 this week. I happens in Firefox but not in Google Chrome.

When I click on a link in gmail it goes to https://mail.google.com/mail/?ui=2&view=bsp&ver=ohhl4rw8mbn4 A blank screen and the status says "done." This happens with old emails that worked before my upgrade. If I right-click and select "Open link in new window" it goes to the correct page.

I can't open any blank tabs, but I can right click and open a link in a new tab. I haven't changed anything, and I don't have the Ask toolbar at all, which is the only answer I could find on the forums, so it doesn't help in my case.

I downloaded and installed Firefox 4, but the fonts on every page look edgy and blurry like I have no ClearType enabled. the only suggestion I've found is to disable hardware acceleration. This helps a bit, but is there a way to fix font problem in some other way because I don't want to disable direct2d
