Firefox Support Forum

Only the upper left quadrant of the Flash Player screen has content. The rest of the screen is either blank or the original static image. This occurs on YouTube and any website that has Flash Player content. Computer is a Macbook Pro Retina using OSX 10.8.4. I've uninstalled and reinstalled Flash Player (twice) and uninstalled and reinstalled Firefox. The problem doesn't occur when I'm using Safari.

As above.Started occurring since v20 came out.Seems like many people have this error.

Reverted to v19.Problems occurs as well.

Tried everything ( starting FF in safe mode , creating a new profile, resetting FF, uninstalling and a fresh install, booting in safe mode Windows). Nothing seems to work.

It freezes again and again only to resume normal service only to freeze again. On and on and on. Really frustrating.

Can someone point to me if this FF's problem or is there a problem with my system itself?

My system doesn't seem to freeze when FF isn't running though.

Firefox does not open, but instead gives the error message, "Failed to read the configuration file." It has worked in the past, but not now.

I REINSTALL 10 TIMES SO DON'T TELL ME THAT!!! I'm piss because i need firefox working again so i can finish reseaching my speech in 5 days.

Hello there,

I've had this problem for a long time, and I've done most everything suggested in other forums regarding this matter. I've disabled "disabled protected mode, disabled hardware acceleration, made sure everything is updated, and nothing works. Unfortunately, this makes Firefox so unusable that I've had to switch to another browser for the time being, but it's having it's own issues. Very frustrating! I like Firefox and would like to have it working, but this "shockwave flash plugin" problem has been a persistent problem for the last year.

I've seen many other users who have not been able to fix the problem via the above suggestions, so--what's the verdict? Is there something else I can try?

Cheers

Hello, everyone!

I've filed a bug report here: https://bugzilla.mozilla.org/show_bug.cgi?id=1004476 The problem is that after installing Firefox 29 with no profile at all and installing any addon that requires a browser restart (NoScript for e.g.) Firefox restarts OK, but after closing it and trying to open again I get a message: "Firefox is already running". I can see in the Task Manager that there is already Firefox running in the background. I've found several people complaining about this issue. Here: http://forums.informaction.com/viewtopic.php?f=10&t=19612 And here: http://forums.mozillazine.org/viewtopic.php?f=9&t=2825639

Thank you in advance

2nd Update. (Comment by a moderator)
Engineers are working on issues that have been identified.
The known issues are problems with Firefox hanging on closedown resulting in Firefox not restarting unless the hung process is killed.

Workaround ensure Firefox is NOT set to clear History on Close down
Use NewButton → Preferences → |Privacy| Firefox will: [Remember History v ]

3rd Update

A fix is now on the Beta Channel Fx30b8 hopefully in a couple of weeks that will be on everyone's Release of Firefox30.

After deleting prefs.js file Firefox does not create a new one.

Firefox does not save any of my settings so i tried all the method described in the following articles:

https://support.mozilla.org/en-US/kb/how-to-fix-preferences-wont-save https://support.mozilla.org/en-US/kb/how-to-fix-preferences-wont-save#w_unable-to-save-any-preferences-or-settings

finally I uninstalled FF completely, deleted the FF installation directory and moved my old profile. Reinstalling FF did not help in anyway. After reinstalling, the preferences were still not saved so I deleted the profs.js file. When I start Firefox it does not create a new profs.js file adn of course my setting are still not saved

What can i do? change? I'd rather fix this than install chrome instead...

I installed Firefox 18.0.1 on 1/19/2013. It continues to crash when I close a tab or when I click File then exit. This problem hits on both my Administration authority account and my User authority account. My Norton Internet Security is current as is Windows 7 64 bit.

Google, ever helpful, has replaced the mp3 attachment player in gmail with something that apparently only works in Chrome. In other browsers, it blames the browser for not being able to play the attachment, and immediately demands that you download the file (preferable to Drive) and get yourself an app to listen. I just want to listen to my damn voicemail without being forced to do it in Chrome nor to preserve it for all posterity. Has anyone got a workaround for this crap?

I just updated to Firefox 32. When I have FF open but hidden in my Dock on my Mac 10.6.8 it will not open links from my email in Outlook 2011 for Mac. All it will do is unhide Firefox from my dock. Once FF is visible and I click the same link in my email it will open a new tab to that web page. If FF is completely closed and I click a link in an email it will launch FF and open the web page. Only when FF is already open but "Hiding" in my Dock will it not open a new tab with the web page when I click a link from email. I didn't have this problem before the update.

FYI, Firefox is my default browser. I opened Safari and have FF listed as my default browser too. When I did the update I did a brand new download and install.

I have an HP Pavillon, Juno email and Firefox is my default browser, At some point while accessing my email I will get the "unresponsive script" error and although it gives my options to continue, debug or close, none of it works and computer freezes. So I have to go to Task Manager and close everything down and start over. Very frustrating. It has also happened when I have been on other websites or with Internet Explorer. HP has tried fixing it, Juno has tried ....all to no avail. I've tried refresh, done many virus/malware scans, etc. It seems to me there is a plug-in or an add-in or some box somewhere not checked. Any ideas?

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?

Immediately after installing Firefox 24.0, the entire look of my Yahoo Mail page changed, and all the usual icons for reply, attach, forward etc. disappeared and were replaced by small boxes with letters in them. I don't have this problem in Safari.

after updating to firefox 29 and then 29.0.1, the cpu usage that firefox are using are insane,

it ranges between 50%-100% cpu usage.

and it happens even on normal non flash tab,

besides even if the site is using flash, i am using flash block and adblock plus,

so anykind of flash material wont play or uses cpu.

please fix this ASAP, because firefox has now gone from useable to resource hog,

oh and i don't like the new look, because firefox has become more similar to chrome on User interface,

and i don't use chrome, because i don't like the UI, and now firefox tried to be chrome twin ?

i think that's all, thanks in advance.

edit : fixed some typo

Just randomly crashes - we tried all the recommendations and nothing seems to help: updating add-ons; drivers; windows; opening in safe mode did not help; do not have that "bit??" program;
One way that it always consistently crashes is when trying to download the add-on Hebrew Calendar - it starts to download and always crashes within seconds after and before it finishes the download.

Using PC with XP. Firefox had been working fine on this PC for a few years, Have had to fix a few times always before if needed by uninstalling completely if need be and starting all new,

Not this time, Have version 22.0 installed, no add on's since I reinstalled so should be clean install no ext or plug ins added yet, but it still does not run in normal mode, only in safe mode.

Some HTML5 videos won't play in my Firefox browser.

This vine for example (https://vine.co/v/b3v5h3Piwt7) only shows up as a static image. I can click the mute/audio button though, but it won't play. When I look at the webconsole when I load the page then 2 javascript warnings show up, the first one say that the Mediasource [long url here] can't be encoded and another one says loading of all candidate sources failed. loading media paused.

I'm using Firefox 21.0 and I tried to run Firefox in safe mode with disabled add-ons, and I also tried to reinstall it, but without success.

Thanks in advance.

Hello,

I've seen this problem listed several times prior to this post, but none of the solutions have helped me.

I've been using Firefox for ages and the last 3 updates or so have been exhibiting this issue. When I attempt to load a website, Firefox will begin to take me to the page and then hang. The circle in the tab will stop moving and it will sit there until I move the mouse or press a button on the keyboard. As long as the mouse is continuously moving or keyboard buttons are pressed, the page will load fine. The same thing happens with YouTube. The video will start and then freeze unless the mouse/keyboard is moved. Firefox also exhibits this behavior when I try to download a file from a website. The download will start and then hang until I move the mouse or press a button, then it will continue for a few seconds and hang again until I repeat the mouse movement or keyboard button press.

So far, I've tried updating Firefox, Java and Flash; starting Firefox in Safe Mode; uninstalling and reinstalling Firefox: doing a complete uninstall and reinstall of Firefox with profile removal and creation. I've run the following ad and malware detection tools with no infections found: Malwarebytes' Anti-Malware, AdwCleaner, SuperAntispyware, Microsoft Safety Scanner, Windows Defender, Spybot Search & Destroy, Kasperky Free Security Scan and Anti-rootkit utility TDSSKiller.

The only thing that I've tried that "seemed" to work was starting Windows in Safe Mode with networking and running Firefox there. I was able to watch YouTube videos without freezing and websites appeared to load properly. Obviously, I can't run in Safe Mode all the time.

I've attached a screenshot of what it looks like when Firefox hangs on Google News. Notice that the images partly load, but a good number of them are either waiting or not loaded.

I hope someone can help me, since I really like Firefox and I'd hate to switch to Chrome or (shudder) IE.

Thanks in advance for your help!
