Why does Firefox frequently spin at (Not Responding) when navigating, then finally load after a delay?

I just updated to Windows 7 and Firefox 7. This has been happening navigating within the mozilla.com site, yahoo, and white pages (where I've noticed it so far). I will click to open something, and it will spin, and then the top line will say "Firefox Not Responding". Then after a while it usually loads. But sometimes it takes a minute or longer. I checked on Internet Explorer, and there is no delay for those sites.

The default of the pref network.http.max-connections has been increased from 30 to 256 in Firefox 6+ versions.
Try to decrease the value of the pref network.http.max-connections from 256 to 30 as used in Firefox 3 versions.

Why does Firefox keep on saying not responding when playing games a on Facebook and on other wesites that has to do with Facebook?

it is very slow

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

Why does Firefox re-jump to a page when it is finished loading or when automatically refreshing?

If I change tabs or windows within Firefox or switch from Firefox to another open programme running, and the browser page has not completely loaded (or sometimes refreshes due to automatic updating) what I see on the monitor is not the tab or window highlighted in the tab bar (or for that matter programme highlighted in the taskbar). Firefox just jumps back on its own accord and leaves me with often with a view that is conglomeration of the reloading page and the other programm I am working on.

Another user posted a screenshot of something like that earlier this afternoon, and I'm not sure what is causing that to happen. I suspect if may be caused by an extension that was recently updated, but no ideas about which one it may be. I just got back to my computer after be gone for the last five hours, so I don't if there has been any additional information in the other thread or not. This is about all I can figure to do right now until we have more information related to this new issue.
Do you have that problem when running in the Firefox SafeMode?

In the home page why does Firefox say I haven't upgraded when I have. This has been going on for over three weeks, I am now on 9 and still it says I have not upgraded.

In the home page why does Firefox say I haven't upgraded when I have. So I upgrade again and still it says I haven't next time I log on. Today I upgraded to 9, it said congratulations on upgrading, I log off then log back on only to be told yet again I need to upgrade. What is going on?

You may see that message below the Google search box on www.google.com/firefox which is the old Firefox default home page. It appears that page is no longer being maintained. You appear to have Firefox 8.0.1 installed which is the latest version.
'''If you want the Google search page as your home page,''' change your home page to '''''about:home''''' (a new, updated version is now built-in to Firefox).

Why does Firefox keep hanging, crashing, sulking, dying when internet connection behaves?

Why does Firefox keep hanging, crashing, sulking, dying when internet connection behaves? Once it renders the page it should forget about the page. Why does it behave when some link is clicked when there is no internet? It should just say internet not available or some crap. Why die, sulk, crash?? I don't get it! 3 series was much much much better!

I should add, I've re-downloaded Firefox, but that doesn't look like it has helped any. Still get seemingly inexplicable crashes.

Why does phone say "this device not supported" when charging

If it is clean connect a 2nd accessory of the same kind to see if you need to replace the accessory or continue troubleshooting the phone.

HT3887 why does my iPhone say device not supported when connecting to my make even after it has successfully paired?

why does my iphone say device not supported when connecting to my mac pro, even though it has already succesfuly paired? I also use a wirless bluetooth keyboard and mouse on the computer successfully.
Also when I turn Bluetooth on on the phone the devices cog never stops turning (forever serching for a device)

iTunes automatically syncs voice memos to your iTunes library when you connect iPhone to your computer.
It couldn't be much easier than that as you don't actually have to do anything more than normal.
This lets you listen to voice memos on your computer and provides a backup if you delete them from iPhone.
Voice memos are synced to the Voice Memos playlist. iTunes creates the playlist if it doesn’t exist. When you sync voice memos to iTunes, they remain in the Voice Memos application until you delete them. If you delete a voice memo on iPhone, it isn’t deleted from the Voice Memos playlist in iTunes. However, if you delete a voice memo from iTunes, it is deleted from iPhone the next time you sync with iTunes.
USB syncing is far faster than Bluetooth.

HT1695 why does my internet say server not responding on my I phone

need help with my internet on my I phone. keeps saying server not responding.

Because it is not responding.
Seriously... you have to ask that question... I would think even the most unintelligent individuals could figure that out.
Do you have an intelligent question or a real issue?

How can I go back to Firefox 5, the 6 update is terrible, constantly get 'not responding' when navigating.

I want to know if I can go back to Firefox vs 5 until vs 7 comes out? I am constantly getting 'not responding' from the browser when navigating through tabs and sites. (ie. if on say facebook, after maybe writing a comment or viewing a picture, I'll click on a second picture or other comment and I have to wait for the browser to 'respond'. This happens on multiple sites and multiple tabs.
I thought it was my internet connection at first but after trying Chrome and explorer browsers I do not have this issue.
It is really irritating and annoying. I did not have this issue with vs 5.

Have you tried the steps at [http://www.roboform.com/support/faq/roboform-v7#faq_firefox http://www.roboform.com/support/faq/roboform-v7#faq_firefox] ?
Firefox 5 is not recommended for security reasons, but if you don't want 6.0 you can try 3.6.x: [http://www.mozilla.org/en-US/firefox/all-older.html]

Get message firefox already running but not responding when trying to launch..tells me to close firefox wondow and try again (no ffox window is open)

When trying to launch Firefox I get the following message.
"Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system."
This is not the first time and I am tired of having to restart my computer. BTW I have Firefox as my default browser, but had to use IE to get to this support site!
In answer to the next question...every time I TRY to open Firefox.

Simple fix for you I think--it works for me.
1. Open your TASK MANAGER (rt click on your taskbar)
2. Go to PROCESSES
3. Scroll down until you see "firefox.exe"(or anything with the word Firefox in it)
4. Click(highlight) the "firefox.exe"
5. At the bottom right side,click "End Process"
6. Close the Task Manager and do whatever you were attempting to do.

FCE 4 hanging/not responding when navigating through photos to import/open

Hi all,
when I select the OPEN (or IMPORT) item in the FILE menu and I navigate through or scroll the images (presented as thumbnails and to be potentially imported) in my HDD or in iphoto events, after a certain moment the spinning wheel appears and FCE hangs / does not respond at all: only solution is the forced quit. CPU seems to work at this moment but not at full throttle because of the hang. This does not happen by doing the same with Imovie...
May you please tell me if you have a similar behavior please? I have FCE 4.0.1 and all latest updates have been installed;
thanks
Emanuele

Small precision:
the hanging / freezing occurs when navigating inside the iphoto library (under the MEDIA title of the right bar of the finder-like window of the OPEN or IMPORT option). No hanging occurs when I scroll the thumbnail images of the ALL IMAGES folder: in spite of this the scrolling may be choppy with transient spinning wheel appearance but without hang...This problem has been reported in another post too, and I would like please to have confirmation then that it is normal to have this hang with iphoto library navigation in FCE from the open / import option.
May you please also tell me if you have a choppy thumbnail scrolling of all your images (in the ALL IMAGES folder) when trying to IMPORT / OPEN?
Cheers and thanks

Why does Firefox frequently and randomly crash?

Hi there, for the last couple months Firefox has gone from rock solid stability to frequently crashing randomly. The crashes occur when I'm actively browsing or not doing anything - I can't identify any particular action that is causing the crashes. The crash IDs are seemingly random and from a variety of sources.
Here are 5 recent crash ID's:
c97123e4-154d-40e9-b062-0adad2101025

Much thanks!

Does this occur when you click links in search engine results? There were some malware around that did this, which you can read about by searching for "Google Redirect Virus". Some are quite difficult to remove.

Why does Firefox 29.0.1 not show any footer

I recently installed Firefox 29.0.1 on an XP system, and have carefully reviewed all the settings. I've downloaded a few personas. It seems to render all web sites appropriately. However, I'm concerned that I may be missing something - the footer. The documentation on creating personas shows that they consist of a header image, and a thin footer image. I have a persona applied at the moment, but see only its header, and not its footer. I get the same result if I switch to the default blue theme. It does not matter whether or not the window is maximized. The scrollable area of any website extends to the bottom of my screen if maximized, or otherwise to the bottom of the window's scrollable area.
My main concern is not aesthetics, but that I may be lacking some functionality. I saw an example of a footer image on the page that documents the creation of personas. The footer shown in the image has a small fox icon with a dropdown arrow at one end, and an "x" near the other. I presume that the icon and arrow might provide some kind of functionality, and/or that useful information might sometimes be displayed in the footer. Can you tell me if I should be seeing a footer, and if so, what might be preventing its display?

In Firefox 29, the Add-on bar was consolidated into the main navigation toolbar, so it's normal not to have that bar at the bottom of the window. There are a couple of extensions which can restore the bar, but unless you are missing it (or some of your extensions require it), then you may not need to do anything.
