Why does Firefox freeze up after a few moments?

For about a week the internet freezes up and I get no response on any buttons or attempts to even close a web page. In frustration I reboot the computer and open with Internet Explorer and have no trouble.
This is a constant problem and I want to use Firefox because I have a dislike of Microsoft methods of forcing us to use their products.

Try to determine exactly what the content is that is causing problems, is it for instance opening .pdf type files or specific types of images ?
* Tools -> Page Info -> Media may give you some clues as to what is common to pages that give problems.
It could also be a problem with your Javascript settings to block or enable
* Tools -> Options -> Content
Or one or more of your extensions could be causing problems see
* [[Basic troubleshooting]]
*Note if you use [[Safe Mode]] do not initially make any changes on the first screen you see just use the continue button.

Why does my ping increase after a few minutes of resetting AirPort?

I connect various phones and my Macbook Air to WIFI using my AirPort Express. I have been plagued with WIFI and ISP problems and recently upgraded my modem to try and fix this issue that persists to this day. I feel like I have narrowed down the problem to my AirPort Express.
After resetting my Airport everything appears to be running smoothly. My download/upload speeds are adequate, I have a very strong WIFI signal, all is well. When I go to play online games I notice an increase in my ping within 10 minutes of resetting my Airport. It happens fairly abruptly - it is not an incremental change. For example I am usually jumping from ~100ms to ~450ms. This happens on multiple servers and can't be tied to one host.
After resetting my AirPort my ping goes back down to normal but jumps up after a few moments. I have my Arris modem set to bridge, and I've tried connecting to the 5GHz channel through the router and there doesn't seem to be any difference.
This problem started a month or so ago. The AirPort has worked absolutely perfectly for a couple of years now. It is really only the ping in online games that seem to be effected – my download/upload speeds are running well which has me stumped.
AirPort Express
Version 7.6.4
Serial number C86HV4YPDV2R
I really appreciate any help! I am out of warranty with the device to call apple and I've spent more than a lifetime on the phone with TWC.

Wireless is extraordinarily complicated. It is more a wonder that it works that doesn't.
Two follow up questions. First, I have taken both the phones in the household off wifi as well as my Roku and that didn't make any noticeable differences.
It is worth a try.. it is wireless after all.. voodoo in another medium.
your answer doesn't really help with two issues. My computer used to connect with no ping increase before this sudden change and why does this change start happening after a few moments of clarity and then skyrocketing pings?
How old is your Express? Anything more than 3 years can suffer due to build quality.. apple is no different to other brands now. A sudden change can indicate poor internals.
7.6.4 is lousy firmware.. test with 7.6.1 if that is possible. (newest ones may not downgrade)
I personally have heaps of Extreme and TC but avoid the express.. it is expensive for what it is.. a very low end wireless AP that can double up as a router at a pinch.
If you have an old Express that you upgraded the firmware.. you may not have noticed the upgrade coincided with the poor pings.. but it can happen.
Also Mavericks.. if you upgrade installed mavericks it can have dire effects on the wireless.. even the latest update to Mavericks has been causing wireless issues. Mavericks and networking is somewhat akin to tin cans and wet string. With the string fraying.
So reset to factory.
Downgrade the firmware.. then reset to factory a second time..
Test it with short names, no spaces and pure alphanumeric.. NOT apple names.. since mavericks changed to SMB networking from AFP in previous versions.
Downgrade firmware by holding down the option key whilst you select version number. Pick from the list that will appear.
Test close to the Express..
Test with no wireless security.. remember it is a test.
Run the wireless diagnostics on the computer to see if it shows anything.
About Wireless Diagnostics
The reason for increase in ping times, can be link speeds dropping, WMM failing.. as it seems to .. or just plain old bad drivers.
I have made huge improvements in things like latency in routers that allow actual settings on the wireless to be changed.. packet size in particular.. one serious issue here is Apple have not given us access to any settings.. in airport particularly but even in the Mac.. this stuff is hidden from end users.

Why does Firefox freeze my computer when I click on an email address or link to a page that asks for contact information?

when i click on an email link, my computer freezes and firefox will open new tabs until i force quit the application. i downloaded the latest version of firefox for a mac, but it did not help. how do i correct this problem?

Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.2.14) Gecko/20110218 Firefox/3.6.14
When I click on a mailto: link, Firefox freezes. This is new for me as of 3.6.14 (not sure if it existed in prior versions because I hadn't clicked a mailto: in a while).

Why does firefox freeze my AOL connection to install updates?

Why does Firefox freeze and/crash shortly after I install "updates"?

Recently, after I have installed a newer version of Firefox, or updates you have provided my system freezes, won't open sites I access. This also affects my e-mail accounts!
It's almost enough to make me reluctantly revert to Ineternet Explorer.'''bold text'''

Why does Firefox send me back a few pages when I attempt to type into a text box???

I am sick and tired of this insane bug. It affects me on a daily basis. 20% of the time I attempt to type anything into any text box, for every keypress, Firefox will treat them as requests to 'go back' and it launches me several pages backwards through my browsing history in the tab. I then I have to skip forward and attempt filling it in again. It usually works after 1-2 attempts but like i said this is happening 20% of the time on text input forms, especially FARK.com.
== This happened ==
A few times a week
== Year or two ago

Start Firefox in [[Safe Mode]] to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
See [[Troubleshooting extensions and themes]] and [[Troubleshooting plugins]]
If it does work in Safe-mode then disable all your extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
You can use "Disable all add-ons" on the [[Safe mode]] start window to disable all extensions.
You have to close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")

Why does Firefox freeze every time I try to install Adobe Flash player? I have uninstalled it and reinstalled it with and without the plugin container.

When I have Adobe Flash player installed and I open Firefox it will freeze up as soon as I open an additional tab other than my home page tab. In order to close Firefox after it freezes I have to use my Windows Task Manager to end process. As soon as I uninstall Adobe Flash player and reboot and then open Firefox it works fine.

Why does FireFox freeze and the only way to unfreeze it is to open the task manager and close the plugin-container.exe file??? It has been happening more and more often and it is getting VERY AGGRAVATING!!!!!

When Firefox does freeze (not responding appears in parentheses in the page tab) I am not able to access any of the webpages (the entire webpage is hidden behind a vaguely white transparent foreground) and more often than not any files I might be downloading are stopped before the entire file has been transferred - which means that I have to start those downloads from the beginning AGAIN. This has been happening for quite some time and I AM SICK AND TIRED OF IT HAPPENING!!
If it continues to happen for much longer I will swear off FireFox FOREVER!!!!! Either a program works or it does not work and lately Firefox has not worked worth a damn...........
The ONLY way to force Firefox to allow me to access it is for me to end the plugin-container.exe file process using Task Manager. Clearing there is a SERIOUS problem here that has not been resolved - why not???

The pluging container opens up unnecessary copies as the cookies/history are cleared, this is a known issue, it might be what you are seeing, and it is hoped to be fixed in some future release of firerox.
There are some hangs affecting some users, with symptoms being high cpu usage, occurring as bookmark changes or syncing is in progress, there is a work around for that.

Why does Firefox not launch after safe boot?

Folks:
I've been using ML for several months, no particular issues, yesterday as part of the monthly maintenance I did a safe boot, and after that firefox will not launch. Other 3rd party apps will launch, and of course Safari will . . . but, any thoughts as to why FF would go "limp"? When I click on it in the dock the icon bounces but then returns to the dock . . . I tried to launch it from the application folder and from the "previous application" launcher . . . . I tried it in a "guest" account that is never used . . . no difference. I did try to do something in the Terminal, but since I'm thinking that very soon I'm switching up to Mav, I haven't bothered to figure out how to add my regular user account to the sudoers list. But, I did try to launch FF in my admin account by the regular methods yesterday, no luck. Any ideas why this is happening . . . to me? Solutions are better, but, conspiracy theories also accepted . . . . =8 - 0
e.e.p.

Ran "Repair Permissions" several times . . . seems to be fixed.

Why does it crash everyone after a few seconds of playback?

I try to playback a podcast but the app crashes and goes to the home screen. I hear a good 10-15 seconds then stops. Why is it doing this?

I'm having this problem as well. In my case I'm getting partial 0 byte files, sometimes with temporary hex file names with the .mp4 extension.
I copied the whole library (which was new and only contained one project) over to my laptop, where export then went just fine. I've also been having other QuickTime related issues. You can help pin this down with a few tests:
Open a short .mov video (best taken on iPhone, import with Image Capture) in QuickTime X. Attempt to export to 480p. Does QT crash?
Try to import the same .mov video in iPhoto 9.5.x. Does it import normally to iPhoto? Or do you get "unrecognized format" errors?
Do you see any crash logs for ProTranscoderTool_sb in Console?
If you search for iMovie in console, do you find any lines that mention problems with these files?:
/Library/CoreMediaIO/Plug-Ins/FCP-DAL/iOSScreenCapture.plugin/Contents/MacOS/iOS ScreenCapture
"The bundle “iLMBPhotosPlugin” couldn’t be loaded because it is damaged or missing necessary resources."
/Library/Application Support/iLifeMediaBrowser/Plug-Ins/iLMBPhotosPlugin.ilmbplugin/Contents/MacOS/i LMBPhotosPlugin
I also wonder if there's any conflict/issue with FCP being installed. Not very helpful but see this link:

Why does Firefox leak memory after. I do the same operations in Firefox and Safari, Firefox in some cases uses over 500 MB of RAM, Safari uses about 50 MB

After opening and closing 5 windows in Firefox and Safari, at rest Firefox still claimed (approx.) 500MB of real memory, Safari return all memory and claimed only (approx.) 50MB at rest (all windows closed). My laptop starts over heating when browsing just simple information pages in Firefox. This still happens after updating to the latest browser.

Start Firefox in <u>[[Safe Mode]]</u> to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance/Themes).
*Don't make any changes on the Safe mode start window.

Why does firefox freeze and then doesn't fully release from memory, but I have to End Process from Task Manager?

Frequently, Firefox for Windows (Vista) freezes up. I click on a link or try to go to another web page and nothing happens. The icon in the tab is just spinning, with Connecting. but it never connects. Then when I close it - if it lets me. I click to open it again and a window pops up saying that Firefox is already running, to please close it before launching it again. I have to go to Task Manager and End task from the Processes tab. It is also a resource hog including the Plug-In Container.

Why does iTunes freeze up for minutes at a time when modifying INFO (CMD-i) ? My files are not corrupted after it is done like many other threads i have readed.

Why does iTunes freeze up for minutes at a time when modifying INFO (CMD-i) ? My files are not corrupted after it is done like many other threads i have readed. Sometimes it's changing the title of a movie or editing the season and episode number of a TV show ect.....

Yup same here
I am running the latest iTunes, the latest updates to the OS and on an iMac 3.4GHz Quad core i7 with 8GB of RAM and the music stored on local HDD.
Still locks up iTunes for between 2 minutes up to 20 minutes.
Really annoying.
If you find a fix please, please let me know, I have just been throwing hardware at it with no joy at all

Why does firefox switch back to bookmarks after I am on a web page ?

This happens every time I go from selecting a bookmark to that page. It just annoying enough for me to yank my hair out, if i had any. Thanks, Max

I have two antivirus programs on my computer. The default windows thing and MalwareBytes (which I perform a full scan with everyday) and I still have the problem.
Hate to be a "problem child" but could anyone post an answer to this problem that isn't something that is obvious that should be done like resetting firefox or check for a virus or mess with the tabs options which I have tried every combination of the options that could be tried.
I mean does anyone else anywhere have this same problem? What I don't understand is that I posted this question two days ago and it doesn't look like anyone else has asked for help with this same issue.
What I really don't understand is why I can't find out anything doing an internet search using "why does Firefox keep returning to the webpage i am currently on when i open a new webpage" and so far no one has suggested something I have already tried.
If Mozilla had some kind of phone number or email contact info then I could probably get this whole thing solved!!!!!!!!!!!!!!!!!!!!!!!!

Why does firefox 7 crashes the system if Quadro NVS 135M graphics driver is installed?

Why does firefox 7 crashes the system with a Quadro NVS 135M graphics cards installed?
It happens immediately after opening Firefox on a two screen system. You get a message saying the Graphics Driver stopped responding, but that it managed to recover, but after a while the system freezes completely. You can't even CTRL+ALT+DEL.

I get this too on with my nVidia GTX460 card. In my case the screen goes black. It happens once every few days, and for a while I could not figure out why. I was forcing a shutdown to get the screen back.
But I put the computer to sleep and woke it up, since that restarts the video, and this let me see what was wrong. The only error message is it reports that Firefox hung. There is nothing else in the Event logs.
I'm running Windows 7 with all the updates from Windows Update, and my video driver is 285.62, but his also happened with the 260.26 driver.
I imagine this is happening a lot, but people aren't able to isolate the cause.
I'm looking for a fix, not a bypass.
