Firefox UI becomes completely unresponsive in debugging mode.

I'm using Firefox for web development, and set breakpoints with the `debugger` keyword, or the breakpoint UI in the "Debugger" section of the "Web Developer" tools. I remember that used to work on older versions, but recently it started failing.
Now, when I enter debugging mode (i.e. hit a breakpoint), the debugger UI shows, but it is completely unresponsive: the mouse cursor doesn't change when I hover over any widget, and clicking does nothing.
The only way to get any response is CTRL-r refresh which *sometimes* works, as well as closing the entire Firefox window. Of course, that means I can't actually use it to debug.
I'm on Xubuntu 13.10, running latest stable 64bit Firefox (3.1.1). I also verified the exact same bug on the nightly binary release (firefox-36.0a1.en-US.linux-x86_64.tar.bz2) as well as the recently released Developer Edition (firefox-35.0a2.en-US.linux-x86_64.tar.bz2).

HI dunpealer,
Please do file a bug on this and make sure to put version 35 and os linux on bugzilla.mozilla.org.
I am sorry it took so long to get back to you, I also can reproduce this. If you have any questions about bugzilla we are happy to help here as well.
Thank you!

I'm running Windows 7 and occasionally, Firefox will become completely unresponsive and grey out, then none of my programs will open at all, including the Start menu, forcing me to use a hard restart and shut down. Any help would be appreciated.

I'm not able to close and restart Firefox at all, since the computer becomes completely unresponsive, save for mouse input. Task Manager is also of no use.

Then let it do all 6 of it's things.
At least it'll eliminate some questions if it doesn't fix it.
The 6 things it does are...
Correct any Disk problems.
Repair Permissions.
Clear out Cache Files.
Repair/check several plist files.
Dump the VM files for a fresh start.
Trash old Log files.
First reboot will be slower, sometimes 2 or 3 restarts will be required for full benefit... my guess is files relying upon other files relying upon other files! :-)
Disconnect the USB cable from any Uninterruptible Power Supply so the system doesn't shut down in the middle of the process.

Everytime I open Firefox it functions for a matter of seconds before freezing and becoming completely unresponsive, what can be done about this?

After freezing up today(which it has done from time to time before), Firefox has now become completely unresponsive. I have repeatedly attempted to restart it but the program will freeze up almost immeadiately every time, each time requiring a close via the task manager.
Nothing has changed since last night except for this unresponsivness. I just tried uninstalling my older version and downloading the current version but the problem has persisted. What else can I try?

I have the same problem on two Windows 7 x64 installations.
Firefox 4.0.1
Addons in common: Firebug
Firefox does not crash, it just becomes unresponsive, but the moment it becomes responsive again (couple seconds to 15 seconds or more,) it will just become unresponsive again. There is next to no CPU usage and there is nothing running in the background that could possible slow it down. I also notice that FF momentarily will stop responding for around 1/2 to 1 second. Then continue to be fine. I'm finding that Chrome is acting up as well but IE is working fine. I also found that Google.com seems to exacerbate the problem.

Everytime I put my Mac Mini to Sleep, Finder becomes completely unresponsive. How do i fix this?

Hi,
Everytime I put my Mac Mini to Sleep, Finder becomes completely unresponsive. I've tried several Terminal commands to kill/quit/relaunch it, but nothing seems to work. Once my Mac has been put to sleep there is nothing I can do to get it back after I have woken it up. I always have to restart my computer, and even then, I have to hold the power button to shut it down because it will never fully shut down from the restart. I have a feeling that Finder is still running in the background and not allowing the mac to shut down. I'd rather not have to reinstall my OS. Does anyone have any idea what may be causing this problem?
Thanks,
Andrew

Hi Andrew, what all is connected USB wise?
One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for Sleep/Wake problem in Safe Mode...
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
Reboot, test again.
If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or some USB or Firewire device, or 3rd party add-on, Check System Preferences>Accounts>Login Items window to see if it or something relevant is listed.
Check the System Preferences>Other Row, for 3rd party Pref Panes.
Also look in these if they exist, some are invisible...

IPhone 4 becoming completely unresponsive for no obvious reason.

My iPhone had been charging overnight with no previous problems ever encountered since i first bought it just over two months ago.
After checking the time on it (apparently working fine), i got up half an hour later putting the iPhone in my pocket.
WHen i next checked it, it had become totally unresponsive and seemed to have completely died.
It had definitely been fully charged and plugging it in to a charger has no response.
Plugging into a computer also has no response.
Attempting to reset by holding down sleep+home for ten seconds also carries no response.
Very frustrating and and i would be very grateful for any help recieved

Ochman, the same issue happened to me, simply hold down both the home and power buttons for 10 seconds then release the power button while still pressing on the home button. The apple logo should pop on screen and the phone should start loading again.

Why had iTunes become completely unresponsive?

Over the past few months itunes has become increasingly unresponsive, I now hate the those spinning colours. I have a large movie and music library stored on an external hard drive (WD 1.5 TB) and I have used just over half its capacity and it connects to a desktop Mac 5 (bought in 2009 I think?). Every action is met with the spinning colours, scrolling a library to pick movies to download to my iphone 4s can take 30 minutes and syncing a movie to the phone takes over an hour. The final straw has been IOS7 which I installed yesterday. Every item I try to sync to the phone fails. I don't use the cloud as I haven't got my head round why it works for me (I get how it works in general terms)
I'm sure there's an easy fix or theres a capacity issue but right now I'm soo out of love with all Apple products I feel like scrapping the lots and starting again with a PC and Android.
Please let me know if there is anything I can do to speed things up, this feels like I have a ZX Spectrum and I'm back in the 80's
Thanks

Firefox becomes completely unresponsive after loading Bejeweled Blitz on FaceBook.

It is the only place it has occurred. I like to play and so does wifey. '''Sometimes''' the game will load (without hanging) and as soon as you click on anything within the game box (except the spin button) it freezes and hangs. It doesn't report it to Mozilla that I am aware of and the only generated report is to Microsoft.
I am running Win7 64-bit, Firefox 3.6.10 with full updated plug-ins.
The only thing I have found that will "sorta" get around this is defining the 'dom.ipc.plugins.timeoutSecs' in the about:config down to -1. I don't know what this will do with other sites and its still not a real fix for this problem, as it seems to repeat after a reload of the page.
I have tried a reinstall of Firefox; scanned computer for viruses; tried the troubleshooting suggestions; turned off all of my extensions.
This problem only occurs when loading Bejeweled Blitz on FaceBook, and nowhere else that I have experienced so far.

You know what? I finally figured it out. I got an error message about AutoPager. I disabled it and the problem went away.
I would like to know though, how did it happen? I have had AutoPager longer than I have been playing Bejeweled Blitz.
The error message said something about a script not loading properly on the page. If you took the time to read this, thanks for your attention, and sorry to have wasted anyone's time.
It figures, I have a problem with it for a few weeks now and as soon as I ask about it, I find a solution. What a crock.

Firefox opens but completely unresponsive even after reinstall

I'd been having problems with Firefox hanging. It didn't appear to have anything to do with any of my addones, as I continued having problems even after disabling them--first one at a time, then all of them. Now after updating to the new version, (thinking that might be the problem) it will open but then immediately hangs (I am unable to even try any of the "fixes"): Error mesasge in toolbar "Firefox is not respponding". I tried completlyuninstalling and reinstalling and that didn't work either. Now the first time I uninstalled and reinstalled I was given the option of deleting my presonal preferences as well, essentially reinstalling a factory fresh Firefox browser. I said no,. Well when the reinsiall didn't work, I tried uninstalling again but this time the option didn't even come up. I have also tried a systm restore without effect. In addition I have run a complete virus scan with AVG and I'm coming up clean. There are several odd things about this glitch: At some point an addon that synchonized my FF favorites with my other browsers erased the back ups on the other browsers (it isn't supposed to do that if shut off as far as I know or I would have chosen a different method). I can't locate my FF favorites in order to save the file (I really want to keep them). The favorites bar is still on the toolbar, so they do seem to be intact on FF, of course I can't access anything. I am completely flummoxed given that even uninstalling and reinstalling hasn't worked. I am not getting any other error messages other than that the browser is not responding. I am currently using Windows 7 on a gateway netbook. The only thing that might possibly have anything to do with this is that at some point some program changed my home page and search engine to Delta. I suspect it was Vuze, but I had selected no and aborted the installation. I still had to manually change them back to my personal defaults. Obviously that shouldn't have affected my browser in this way. The only two other programs I've installed within this time period were from Giveaway of the day and Games giveaway of the Day both reputable websites. None of the feedback from these two programs indicated anything about hijacked home/search engines from other users--who would most definitely be kicking up a fuss. So I have two basic issues: Fixing FF and saving my favorites from FF. Tried again, making sure that the AVG was off, and while it didn't hang the first second, it started hanging as soon as I opened a web page or the add on page. Also note that I cannot install the troubleshooter. I saved the program but it won't install or even apparently recognize that I have FF installed.

Create a new profile as a test to check if your current profile is causing the problems.

I have a L7780 that has become completely unresponsive to all of it's buttons.

Display still looks like it is ready to go, and the printer responds to things like opening the scan table, toner door opening, but all of these seem to be automatic and in reality nothing works. Interior scanning light is on. It is also completelly unresponsive over the network. Anyone ever heard of this problem? Help!

* In Firefox 3.6 versions on Windows and Firefox 4 on Windows and Linux it's possible to hide the "Menu Bar" via "View > Toolbars" or via the right-click context menu of a toolbar.
* Press F10 or press and hold the Alt key down to bring up the "Menu Bar" temporarily.
* Go to "View > Toolbars" or right-click the "Menu Bar" or press Alt+V T to select which toolbars to show or hide (click on an entry to toggle the state).

Second 4th gen nano that has become completely unresponsive

This is my second 4th generation iPod nano. The first stopped working properly on the second day. It wouldn't hold a charge, it wouldn't turn on, and iTunes would not recognize it.
Now it's the same thing. I returned it and got another one. This one worked fine for 6 weeks, and now it does nothing. I tried the 5 R's on the troubleshooting page. Nothing shows up on the screen. Nothing happens when I plug it into the computer, iTunes won't recognize it. Maybe it's time for a recall on this product. What a piece of junk.

hello, maybe it's an issue with the the flash plugin - you could try if [https://support.mozilla.org/en-US/kb/flash-113-crashes#w_solution-2-downgrade-to-flash-10-3 downgrading to flash 10.3] (which is still supported) or [http://forums.adobe.com/thread/1018071#TemporaryWorkaround disabling protected mode] makes a difference.

Premiere becomes completely unresponsive during multi-cam preview

While editing a 5 camera multi-cam project, Premiere completely locks me out during playback of the project. It's like my user interface just completely died. The project plays and nothing I do will stop it. Autosaves do not occur and I am forced to wait an hour for the whole timeline to play (haven't waited to see if I get control even after then) or 'end task' to kill the Premiere application, thus losing all my work up until the last save. I have had moments where Premiere locked my out for a few seconds, but I always managed to eventually get control. The last 2 times I never got control back.
I'm running the latest version of Premiere CC on Windows 8.1.
Any help in how to interrupt Premiere's coma in this situation would be greatly appreciated. Really sucks doing the same work 3+ times over.
Michael

i3770k 16gb RAM.... I don't think that's the problem.
I called Adobe Tech Support and they located the problem. I had the wrong sequence settings, which had the wrong preview format (codec). Apparently, the best way to create a sequence with a multi-cam track is to right-click on the multi-cam clip and select 'create sequence". This way Premiere chooses the optimal preview format for the video clip types it contains. And this is the only way to get Premiere to optimally handle multi-cam clips with various different video formats properly, such as mine.
I don't understand why one even has to worry about this sort of thing. Why shouldn't Premiere ALWAYS choose the optimal playback format? Coming from other editors I always found it really weird in Premiere that I had to select a sequence preset that was related to the video format I was editing. For one thing, many projects have mixed format types so this system that Premiere employs seems flawed and outdated.
Anyways, eventhough Premiere still drops a few frames during playback of my five 1080p streams, I can now edit and watch the multi-cam preview without fear of being completely locked out and losing control of Premiere.

After the recent update My Firefox has become unresponsive alot.

I don't know why but now Firefox has become so unresponsive.

Muse CC 2014.1 becomes totally unresponsive on opening site created in 2014.0

Since upgrading to 2014.1 Muse freezes on opening my last current project and becomes completely unresponsive every time.. I had no issues on 2014.0.   The only thing I can see is it has is "Project Name - Converted" I can't interact with it, and stuck with a beach ball. I have to use Activity Monitor to force quit. I have at least 3 other muse site files doing the exact same thing. None of these are that terribly complicated or large.
OSX 10.9.4, fully up to date.   I have closed all apps, completely rebooted and still having the same issue.   Anyone else having similar problems?   I have the "Force quit" error report I can private message to support.
Edit:   I have emailed the muse file to [email protected]   As stated above, this is not the only site that is a problem, but the main one I need to work on.

mythiix, please download the file http://muse.adobe.com/assets/ftp2014fix.zip, unzip it, and save the contained file "ftpPrefs.xml" to the following location:
On Windows: %appdata%\Roaming\Adobe\Adobe Muse CC\2014.1 (You can copy and paste this in the Path bar at the top of the Windows Explorer window.)
On Mac: ~/Library/Preferences/Adobe/Adobe Muse CC/2014.1 (You can copy and paste this in the Go To Folder dialog using Shift+Command+G in the Finder.)
I believe the hang on open is a result of Muse attempting to check to see whether In-Browser Editing has been used to make updates to your published site and the FTP server on the host being slightly misconfigured. Muse uses FTP Extended Passive Mode (EPSV). It's generally the preferred mode for optimal performance, but we're finding some hosting providers have FTP servers configured such that EPSV is not supported or EPSV only works if you're inside the same firewall as the FTP server. The ftpPrefs.xml file above, turns off EPSV mode. So if that is the problem in this case, putting that file in place should enable you to successfully open your .muse files and upload to your FTP host without hanging/crashing.
Please give this a try and let us know whether or not it enables you to open your files and use File > Upload to FTP Host from within Muse. Thanks.

Application suddenly very slow in debug mode?

I have a WPF desktop application with 10 or so projects. I am using Visual Studio 10.0 SP1. All of a sudden, it has become extremely slow in debug mode - to the point that I can not even debug it.
The same application runs just fine in debug mode on another pc where I am using Visual Studio 2013 Express. I am using SVN to keep the two copies in sync. No new software or windows update has been installed. Even nothing material has changed in the code.
I looked at the VS debug options on both machines and there is no major difference - using default settings.
Any idea what may be wrong? What should I look for?
Thanks.

I take it the path you're using hasn't changed?
You didn't suddenly decide to work off a network drive or pick a very long path to the source ( yes that stuffs things up ).
If you're using the same code and it works fine on one machine but not the other then your visual studio install is probably broke somehow on the slow machine.
I would do an install > refresh.

Completely unresponsive touchscreen

I sent my Lumia 2520 in to troubleshoot the first instance of the completely unresponsive touchscreen in November 2014, just before the one year warranty expired. NOKIA took my device, labeled it "defective" after the inbound inspection. They then "repaired" it and returned it to me two weeks later.
Since then (and sadly, just days after the original one year warranty expired), on multiple occasions the touchscreen has become completely unresponsive. I'm now unable to turn it off or open the sleep screen to login. I've tried the home/power button reset option. Even that doesn't work.
Today when I tried to call their tech support at 888.665.4228, it rings once then times out in dead air.
If my device was identified as "defective," why did I not receive a NEW DEVICE as a replacement?
If the "defect" was repaired, at a minimum, the warranty for that repair should be extended to one year from date of repair, for the original owner.

Check the terms of the warranty which are usually provided as part of the documentation that you receive with the product, otherwise you can find it on the Microsoft web site for your country (warrsnty terms vary according to the laws of the country where the device is sold).
What you have received is normal service for virtually all major manufacturers: if a faulty device can be repaired, then it will be - you only get a replacement if repair proves impossible; and the original warranty does not extend after a repair.
