Firefox 4 randomly hangs for a few seconds

When im browsing, Firefox 4 randomly hangs for ~10 seconds saying its "Not Responding", then it returns to normal.
I dont seem to see a pattern on when it hangs, sometimes its when i open new pages, sometimes im just scrolling, sometimes i'm not doing anything...
It didnt seem to happen before i updated to FFx 4
My best guess is it happens when its trying to "Sync"?
It's not that bad, but it gets annoying after a while.

It is also possible that Firefox is doing maintenance to places.sqlite (bookmarks and history). If you keep a large history or have a lot of bookmarks then you can check that out as well. Also make sure that security (anti-virus) software isn't blocking access to files in the [http://kb.mozillazine.org/Profile_folder_-_Firefox Firefox Profile Folder].
Create a new profile as a test to check if your current profile is causing the problems.<br />

There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins"
If that new profile works then you can transfer some files from the old profile to that new profile (be careful not to copy corrupted files)

Firefox hangs for a few seconds when trying to pause videos or skip ads on Youtube.

Hello all!
My problem is that YouTube sort of hangs for a few seconds when I try to pause a video or skip ahead or skip ads. The video freezes while the audio keeps playing until, after say 5 seconds, youtube finally does what I tell it to do.
This doesn't happen if the video is embedded on a different website, nor does it happen on Vimeo, Dailymotion etc. I can play YouTube videos perfectly while using Chrome, IE and a Windows 8 Youtube app I have.
After the initial freeze all commands start working very well, at least until I open a new video.
I noticed that a lot of people are having trouble with youtube while using firefox and I've tried a few things:
- uninstalling and reinstalling flash and java
- starting Firefox in safe mode
- using different antivirus software
- reinstalling Firefox
I read that this might be a problem caused by the whole Google being all buddy-buddy with Adobe thing, but I'm skeptical.
So, is there any way to get YouTube to work properly?
Thanks!

The speed of image searching isn't a problem for me. The trouble is, the automatic zoom function is lightning fast and I find it disturbing to the point that it makes me feel very ill.
I very much want a way of suppressing it.

FF 30.0 hangs for a few seconds when opening new window

It seems like
https://support.mozilla.org/en-US/questions/984193
It did not start with 30.0 but I upgraded in the hope that it would solve the situation.
Every time I open a new window FF hangs for a few seconds. It does not hang opening a new tab!
I tried the steps described in the above topic but they did not work.
if I open the console and type
gSnippetsMap.clear()
the result is
undefined.
If I type
localStorage['snippets-last-update'] = 0
the result is
[Exception... "Component is not available" nsresult: "0x80040111 (NS_ERROR_NOT_AVAILABLE)" location: "JS frame :: debugger eval code :: <TOP_LEVEL> :: line 1" data: no]
There is no difference if I use "Show a blank page" or "Show my home page" where home page is set to "about:blank" for "When Firefox starts".
BTW, I am using Windows 8.1

Short addition:
After the new window is opened I can type a few characters (max 5) into the searchbar. Only from then the hang begins.

Firefox 3.6.15 keeps stuttering or hanging for a few seconds constantly but its only firefox and nothing else on the computer

I have been using firefox 3.6.15 with no problems since it came out. But just recently it has started to hang or freeze for a few seconds about every 10 seconds. Everything else on the computer still works nothing else is frozen just Firefox. I haven't added anything new to firefox or installed any programs. Adblock Plus and Stumbleupon are the two addons I use.

Hey everyone in Apple world!
I figured out how to fix the flashing yellow screen problem that I've been having on my MBP! Yessssss!!!
I found this super handy website with the golden answer: http://support.apple.com/kb/HT1379
I followed the instructions on this page and here's what I did:
Resetting NVRAM / PRAM
Shut down your Mac.
Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.
I went through the 6 steps above twice, just to make sure I got rid of whatever stuff was holding up my bootup process. Since I did that, my MBP boots up just like normal. No flashing yellow screen anymore!!
(Note that I arrived at this solution when I first saw this page: http://support.apple.com/kb/TS2570?viewlocale=en_US)
Let me know if this works for you!

While actively using the iPhone 5, Apple logo will randomly appear for a few seconds, then show up at the lock screen

This is the weirdest thing I've ever seen an iPhone do. I recently got the iPhone 5 from Verizon, 16GB (if that even matters) running iOS 6.0 respectively. This has happened 3-5 times since I started using it last Friday when they started to deliver. When this incident occurs, I'll be using my phone, as in it's unlocked and it's not just sitting. Then, the Apple logo will appear and if I didn't know any better, I'd think my phone was turning on. However, it only stays that way for a few seconds until it shows the lock screen, imitaing a startup. The weird thing is, the startup time is ~30 seconds everytime I turn my device off and turn it back on. This incident where it'll appear to be just turning on while I'm using the phone will only last for ~5 seconds. Plus, during the incident, it nevers actually turns off the display or goes completely black. It'll just snap directly from me using the phone to the Apple logo, then the lock screen after a few seconds. Also, cellular services are immediately recognized after the incident, when starting up it usually take about 30 seconds. I can't confirm this or not, but I believe this incident occurs when I press the home button to exit an app. However, when it happens it strikes me by surprise and I can't confirm or not if this happens only when I'm exiting an app. Not sure if this is an iPhone 5 specific problem or an iOS 6 problem...I can't really assume it's a bad power connection, since like I said it doesn't imitate a full startup of the phone, it just goes throught the screens (Apple logo -> lock screen.)
And as a side note, I restart my phone daily. And as rare of a problem this is, I'm not going to restore or wipe my phone and start fresh. Just wanted to see if there was anybody else experiencing this problem and to make the problem aware. Thanks in advance for any help!!

I had this same thing happen to me. I was using my brand new iphone 5 (texting and listening to music through the speakers) when it flashed the apple logo, stopped my music and brought me to the lock screen.

Applications randomly freeze for a few seconds?!

Hi guys,
I have had nothing but trouble with this most recent iMac I purchased 4 months ago. It's the 24" described in my profile. AppleCare came out and recently replaced my faulty HDD, and put a 500gb Hitachi in (replacing 500gb Seagate).
Anyway, for no reason, after a fresh install and all the updates, applications will freeze for a few seconds and show the spinning beach ball- doesn't matter what application (Wow, Safari, Quicktime, Skype, Adium, etc.)- anything! I can see in activity monitor that there is a spike in the disk activity at the time, but cannot explain why. It's a brand new hard-drive! Interestingly, there is no corresponding jump in CPU or RAM access, so it's obviously some kind of data-dump issue with the HDD....the new HDD...
Looking in Activity Monitor, it appears to be the data read/sec that is spiking.
This is extremely frustrating, and I thought the new HDD would solve this, but apparently not. I don't particularly wish to reinstall OSX, and AppleCare in Australia is shut at the moment (midnight)
Does anyone know of a solution, or why it's happening?
I never had ANY of these problems with my first 24" that I bought late last year, with stock everything (hdd, gfx, etc.)....I feel like this one is faulty by nature....
Thanks!
EDIT: http://forums.mactalk.com.au/showthread.php?t=36763 shows my original HDD issue with the previous HDD....you can see this *****

It has to be the HDD. Calling Apple in the morning...
Sound like that could be a HDD problem. One way to confirm it is to look at the Console application from your Utilities folder. Look at the System Log and Console Log and see if you see any lines with text like "disk0s2: I/O error." at the times when you see the freezes and hear the clicks. Note that the numbers in the disk0s2 part can change, depending on how your drives are set up.

Thanks, Charles.
Looking at the Console log, it doesn't seem to have any i/o errors. Since both logs are quite lengthy, and the quoting system here is a bit akward, I've linked them:
Console.log: http://www.miraclesalad.com/webtools/clip.php?clip=e04
System.log: http://www.miraclesalad.com/webtools/clip.php?clip=e06
Couldn't really see anything there, but have a look if you'd like. Looking forward to calling Apple Support today and finding out what the deal is...only just got this new HDD put in!

Safari 5.1.7 Bookmarks - adding or changing hangs for a few seconds

Hello all -
Safari 5.1.7 - osx 10.7.4 - MBA
Safari hangs when adding a bookmark or deleting/changing order/moving to new folders etc.
Hangs for about 5 seconds and then completes the task.
It will do the first change just fine, then any further bookmarks adds/changes will hang the browser.
I've tried all the suggested steps, clear cache, reset etc.
Problem comes right back.
Suggestions?
thanks

T410 hangs for a few seconds

My T410 hangs for ~2 seconds at random intervals from 3 minutes to 30 minutes.
Cursor freezes whether using wired or wireless mouse.
Any ideas of where to start my problem solving?
-Ed

I would suspect power manager, cpu throttling. Does it happen when using "maximum performance"? Does it happen more often when on battery power?
There are alot of things which cause cause a momentary pause, a poor behaving device driver, an application which is taking too much processor time at too high a priority (again usually device drivers). If this happens with any predictable frequency it may be useful to have your task manager loaded and see what applications/services are taking system time up.

InDesign CS6 hangs for a few seconds when transforming group (OSX 10.8)

I'm testing InDesign CS6 under OS X 10.8. Seems to work without problems - except one thing which I noticed several times while working on a document (that I was working on under 10.7 as well, without problems):
I transform a group of objects (mostly placed Illustrator EPS) by dragging one corner of the group (with one or more modifier keys). After a few moments InDesign gets unresponsive (it freezes, cursore won't move, although you can change apps via Alt+Tab). Activity monitor shows 100% CPU usage (for one CPU core, at least). After a few seconds, everything goes back to normal.
Process analysis looks sth like that (it goes on and on like this):
This might be a problem related to this very document. On the other hand, this worked flawlessly under 10.7. So maybe someone at Adobe wants to look into that?

Thanks, I'll try that.
In the meanwhile, I opened another document that contains the same group of objects. No hangs here. So this might indeed be a problem related to the document itself.

Mac Mini display randomly blanks for a few seconds....

The Mac Mini that I bought a few weeks ago randomly goes blank for a couple of seconds at a time (black screen). There is no regular interval between occurrences -- sometimes it can go an hour or more between "spasms," other times it may blank two or three times within a ten minute span. Occasionally, it comes back to a snowy screen, that lasts for another couple of seconds, before returning to normal.
I have searched online, and have seen this mentioned in reference to the nVidia 9400, which is the graphics adapter in this model Mac Mini. I have tried both the mini-DVI to DVI adapter, as well as the mini-display port to DVI adapter, as was suggested in one post. The occurrences are less frequent with the mini-display port to DVI adapter, but they still occur with an unacceptable frequency (if occurring at all is acceptable). I have also tried three different flat-panel monitors (Samsung, LG, and Acer), with the same results.
Has anyone else experienced this problem? Does anyone know of a solution, other than returning the computer?
Thanks.

Yes. This is exactly the issue I'm having. I'm both sad, and happy I'm not alone!
I added this message in another post before I found this one.
"I'm using a 27 inch ASUS LCD over DVI from the Mac Mini. It doesn't matter if I use a mini display port to DVI adapter or an HDMI to DVI adapter, the screen will randomly "Flicker" the image into a reversed color image thats slid to one side a bit. Other times it will go black for half a second randomly. And then, after a group of close together "Flickers" it will on occasion go into the "Colored static" issue like you are experiencing.
I can either power cycle the monitor or the Mac to solve the issue. I assume this solves the issue because it forces the Mac to handshake with the DVI connection again, and temporarily resolves it. Some times it will only "Flicker" one or two times a day, other times it will do it in cascades until it goes into the "Colored noise" problem again, which I have only seen a half dozen times in the last few weeks.
The Mac Mini did not do this initially, so I'm thinking it's from one of the boot camp updates? I hope it is, because that means it can be fixed with a patch."
I'll drop apple some feedback. Thanks for the link!

With many open tabs (80+) Firefox regularly (every 10sec) hangs for a few seconds because of session storing where the CPU is at 100%. Btw that is the reason why videos in Firefox are hanging every 10sec, too. Why is this operation so demanding?

When I'm using Firefox for a long time and I'm working with several open windows and many open tabs (80+), Firefox hangs/freezes every 10sec for 1-3sec. This is very annoying. The reason for this seems to be the session store operation, which gets executed every 10sec. In my experience (or rather on my computer) this isn't noticeable when I'm just working with around 40 open tabs.
This also seems to be the reason for hanging videos in firefox (although youtube is quite robust; others are not) because they stop every 10sec, too. For this time (the 1-3sec) the taskmanager tells me that firefox is using all the available cpu power. I'm really wondering why the session store operation has such an influence on Firefox' behaviour.
My computer is a Core 2 Duo E6600 with 3GB RAM and a decent hdd.

Just some additional info:
I just had the problem again, and it even occurred when I did not have any tab open! I did not even use Firefox, but just wanted to start to use it, but it did not respond. There was _nothing_ open, and when I checked the TaskManager, the memory consumption was up to 300 MB, and the CPU was again at 100%. After the CPU was down to 0% again, the memory slowly decreased as well. First, to ~260, then to ~200, now to ~170 MB. Maybe it will decrease even further...

Firefox keeps "not responding" for a few seconds - then connects

I just upgraded to Firfox 4.0 because of my new computer's Windows 7.
It started "not responding" for up to 20 - 30 seconds before it reconnects, and it is sometimes unresponsive to my mouse even when it is working. This did not happen before the upgrade and does not happen with Windows Internet Explorer

check your system preferences to see if you have "ignore accidental trackpad touches" checked (or something like that). If you type on you keyboard then try to use the trackpad you have to touch it a couple of times so the computer does not think it was an accident while typing. Just uncheck the box if it is checked.

In a new tab firefox loads recent windows for a few seconds before going to homepage

When I open a new tab, for a couple of miliseconds before going to my homepage, i can see various sites i recently visited in a table-list like a recent visits table. Am i being tracked by something? Did I catch a trojan ? I am also running no-script add-on on my Mozilla for extra protection. It's not disturbing my browsing experience but I do not wish to be tracked in that way. For example, when I tried loading it today, I could see photos of friends I saw on facebook, and info about an e-bay purchase i wanted to make.

That is probably the about:newtab page that you see.

Firefox lags and freezes for a few seconds every time I want to load a new page or open a new tab

This just started a couple weeks ago, I've tried disabling numerous add-ons and updating plugins but to no avail.

Disabling hardware acceleration seemed to solve the problem. Thank you all very much, but before I close this thread as solved, I've always had that feature enabled to the best of my knowledge. Why did it suddenly cause problems?
