Keep getting (Not Responding) message while attempting to view messages in Thunderbird

After launching Thunderbird and loading new email I continue to receive "(Not Responding)" message in the top application bar. I tried the re-indexing steps after saving the profile folder to a backup drive, but the message continues to come up when attempting to navigate between email messages. I also tried running in "Safe Mode" per instructions, but it continues to occur there as well. Are there settings that I need to adjust to improve performance of this application on my system? I am running Windows 7 on a Dell Inspiron desktop computer. Thanks

Do you use McAfee anti-virus software?
If yes, please read:
* https://wiki.mozilla.org/Thunderbird:Testing:Antivirus_Related_Performance_Issues#McAfee
Is this an Imap mail account?
if yes, you can choose to only synchronize the most recent of emails instead of a whole folder.
see info :
* https://support.mozilla.org/en-US/kb/imap-synchronization#w_configuring-synchronization-and-disk-space-usage
Make sure you compact folders on a regular basis to remove all 'marked as deleted' emails.
Tools -> Account Settings -> Server Settings -> Clean up ("Expunge") Inbox on Exit will compact the Inbox folder when you exit Thunderbird. If you check "Empty Trash on Exit" it will also empty and compact the Trash folder when you exit.

TB keeps getting Not Responding message. Screen freezes. Happens all the time. I am running STOPzilla anti-virus

I get the Not Responding message on both TB and Firefox all the time. I have seen issues using McAfee and a list of other Anti-Virus programs but I use STOPzilla and it is not listed at this time. It gets very annoying when typing something and the screen freezes for several seconds and have the Not Responding message and then it will work again. I am running TB 31.0 and Windows 7. Thank you.

Perhaps someone close (geographically) can give you a hand?

What I described is a one-step test in Thunderbird: ''On the Help menu, click on "Restart with Add-ons Disabled". '' This would help determine if the problem is among an add-on installed in Thunderbird.
If that doesn't show improvement, the problem is not within Thunderbird but elsewhere in the system. Starting the computer in Safe Mode then helps confirm if the problem is in Windows (and not specifically in Thunderbird).
I understand you may not be comfortable doing this by yourself, perhaps ask someone close to help you in person, by showing them our answers here.

MAil often doesn’t fully quit although it appears closed in dock (I have to force quit)
Please follow these directions to delete the Mail "sandbox" folders. In OS X 10.9 there are two sandboxes, while in 10.8 there is only one. If you're running a version older than 10.8, this comment isn't applicable.
Back up all data.
Triple-click anywhere in the line below on this page to select it:
~/Library/Containers/com.apple.mail
Right-click or control-click the highlighted line and select
Services ▹ Reveal
from the contextual menu.* A Finder window should open with a folder named "com.apple.mail" selected. If it does, move the selected folder—not just its contents—to the Desktop. Leave the Finder window open for now.
Log out and log back in. Launch Mail and test. If the problem is resolved, you may have to recreate some of your Mail settings. You can then delete the folder you moved and close the Finder window. If you still have the problem, quit Mail again and put the folder back where it was, overwriting the one that may have been created in its place. Repeat with this line:
~/Library/Containers/com.apple.MailServiceAgent
Caution: If you change any of the contents of the sandbox, but leave the folder itself in place, Mail may crash or not launch at all. Deleting the whole sandbox will cause it to be rebuilt automatically.
*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select
Go ▹ Go to Folder...
from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.

When using Foxfire I keep getting "not responding", how can I fix this?

When using foxfire I keep getting "not responding" How can I correct this?

If this is happening with one or two specific sites, those site may have been hacked, or they may simply be bad sites.
If it's happening with a larger number of sites, and with sites that are legit (like Google, Yahoo, Facebook, etc), then it's likely that your wireless router has been hacked. See:

I keep getting NOT RESPONDING when browsing ebay.

Hello Connie.
You may be having a problem with some extension or plugin that is hindering your Firefox's normal behavior. Have you tried disabling all add-ons (just to check), to see if Firefox goes back to normal?

Keep getting "not responding" error message as DW hangs

I have had the following problem consistently used DW 12.1, as well as the version that was with CS 5.5. And I am almost sure it has something to do with the html or other code on my pages, but I thought a DW guru might help.
Basics First: DW 12.1 with the subscription. 64 bit Window 7.
Files that I am editing will periodically freeze, and then I get the "not responding" message above the menu bar. It freezes for 10 to 30 seconds (IT FEELS LIKE 10 TO 30 HOURS) and then starts working again.
Of course it only seems to happen when I'm on a roll making many duplicate mundane edits and then BOOM... can't do anything except shoot laser eye daggers at the screen and try to prevent myself from hyperventilating.
Here's the thing. I work on many sites; and this generally only happens on the site of my main client. I work off o local copies of the site, but I inherited them and they are massively full of bloat code, scripts, etc. I would not be surprised in the least if DW is trying to run or access some of this and this is the cause.
I turned off the "Display external files" option; are there other options I should try? It really is the absolute most annoying thing in my life right now (we should all be so lucky) and I'm hoping you might have a way to fix it.
I'd be happy to post code, but this page is a typical example where I might get the error 10 times in a 30 minutes while working on it...
http://www.healthfirst.com/acls-kit.html
Thanks!

Retard, (I know that sounds hilarious, but I don't know your name - no offense please! )
Like you said, if this happens only primarily on one of the many sites, it generally comes down to the type of code on that site.
And after looking at the URL you posted, seems like that page uses a lot of external references - JS and CSS.
Especially the last few lines:
<script type="text/javascript" src="http://njcdn.worldsecuresystems.com/CatalystScripts/Java_OnlineShopping.js?vs=b1763.r38875 7"></script>
<script type="text/javascript" src="http://njcdn.worldsecuresystems.com/CatalystScripts/Java_Cookies.js?vs=b1763.r388757"></script>
<script type="text/javascript" src="http://njcdn.worldsecuresystems.com/CatalystScripts/Java_Box.js?vs=b1763.r388757"></script>
Also, a couple CSS, JS references in the <head> section.
'Display External Files' only disables showing external files - but still loads them.
Can you try removing the external references and try working with the webpage in DW for a few minutes to see if the same problem persists? If it does, we know what was causing your issue.
Also, run your site through W3 validator to check and resolve errors: http://validator.w3.org/check?uri=http%3A%2F%2Fwww.healthfirst.com%2Facls-kit.html&charset =%28detect+automatically%29&doctype=Inline&group=0
Let us know how it goes.
Good luck.

I get constant "Not Responding" messages and Thunderbird freezes. I've done everything suggested on this forum. Nothing helps.

I've done everything I can find in this forum - using Safe mode, changing McAfee settings, etc., etc., etc. I downloaded Thunderbird again and reinstalled it. Nothing helps. I can look at one email but if I try to delete it I get the "Not responding" message. If I try to go to the next message I get the "not responding" message. If I try to do anything while the screen is frozen, it goes grey and I get the "not responding" message. Short of changing my email viewer, is there anyway I can fix it.

I have this problem too and it is EXTREMELY frustrating!!!

Keep getting "not responding" when using Yahoo's new version of email on a Win8 Lenovo computer

Firefox no longer works properly. I tried the reset Firefox option, but that did not help. When I try to delete an email, I receive the not responding message. When I try to move an email into a folder I receive the message. When I try just to go to the next email, I receive the message. If I try to mark a message not spam, nothing happens. If I wait, eventually Firefox responds and I can move on to the next email. Obviously this is very time consuming and I find that I just don't read my email as I don't what to spend the time. I contact Yahoo and they responded back that it is a browser issue. Because Firefox is the only browser I have on my computer I need to get this working properly again. One more thing, sometime this non-responsive message shows up when I am using other sites, but just not as often as when I'm trying to read my Yahoo emails.
I thank you in advance for answering my question and try to help me get this issue resolved.

To rule out Flash as a potential culprit, could you try one or both of the following:
(1) Disable the Protected Mode feature of the Flash Player plugin.
The following pages provide different ways to do that:
* Adobe support article under the heading "Last Resort": [http://forums.adobe.com/message/4468493#TemporaryWorkaround Adobe Forums: How do I troubleshoot Flash Player's protected mode for Firefox?]
* Manual steps: https://support.mozilla.org/questions/968190?page=5#answer-509209
* Batch file to automate the manual steps: https://support.mozilla.org/questions/982093#answer-518078
Flash needs to completely unload from memory (restarting Firefox might help) before this would take effect.
(2) Set Flash to Click-to-Play ("Ask to Activate").
This will delay Flash from starting on a page until you approve it, which will help distinguish Flash-generated issues from page load and layout issues.
To set "Ask to Activate", open the Add-ons page using either:
* Ctrl+Shift+a
* orange Firefox button (or Tools menu) > Add-ons
In the left column, click Plugins. Look for "Shockwave Flash" and change "Always Activate" to "Ask to Activate".
When you visit a site that wants to use the Flash, you should see a notification icon in the address bar and one of the following: a link in a black rectangle in the page or an infobar sliding down between the toolbar area and the page.

Getting "Not responding" message and bridge freezes

When launching Bridge CC on a PC with Windows 7 it gives a "not responding " message in the title bar. If left alone it will eventually open, but is incredibly slow to go to another folder, gets hung up and gives the same "not responding" message.
It opens to the same folder every time, even if left off at another folder.
I have uninstalled Bridge CC and reinstalled and still get the exact same problem. Also have done registry cleanup and other PC maintenance.
Does anyone know of a solution?

I am getting "Not Responding" message. The fix in the Help is confusing and doesn't seem to match my setup. Using Windows 7 & firefox 7.0.1

The problem started after last update. I tried following the directions in firefox Help without success. They were confusing and the instructions did not match what I was seeing on my screen. I need a simple quick fix thank you.

There could be more than one reason for such messages.
There is a problem sometimes with the database file used for history and bookmarks see
* http://blog.bonardo.net/2011/09/30/is-your-firefor-freezing-at-regular-intervals
There was a change made which seems to affect some Windows users, and has a workaround, but tends to result in images etc not loading rather than a not responding message see
* [[firefox never finishes loading certain websites#w_lower-the-max-number-of-http-connections]]_lower-the-max-number-of-http-connections
Are you getting any other error messages, or indications of problems ?
* not directly related to an update but also see [[firefox hangs]]
* and [[Firefox is already running but is not responding]]
P.S. <br/> I note you have BrowserPlus, that has sometimes, recently, been associated with firefox problems, it would certainly be worth trying temporarily disabling that.

Keep getting not responding everytime i change to another site

i change sites and i get not responding but if i use internet explorer this does not happen.
what is wrong with firefox? i download new version and have even uninstalled it and reinstalled.

Try to disable hardware acceleration in Firefox (you need to close and restart Firefox).
* Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"
* https://support.mozilla.org/kb/Troubleshooting+extensions+and+themes
You can check for problems with current Flash plugin versions and try these:
* disable a possible RealPlayer Browser Record Plugin extension for Firefox and update the RealPlayer if installed
* disable protected mode in the Flash plugin (Flash 11.3+ on Windows Vista and later)
* disable hardware acceleration in the Flash plugin
* http://kb.mozillazine.org/Flash#Troubleshooting

Keep getting not responsive message

If i click on anything I get firefox not responding message continually. even with one window & nothing on it

Hello,
'''Try Firefox Safe Mode''' to see if the problem goes away. [[Troubleshoot Firefox issues using Safe Mode|Firefox Safe Mode]] is a troubleshooting mode that turns off some settings, disables most add-ons (extensions and themes).
If Firefox is open, you can restart in Firefox Safe Mode from the Help menu:
*In Firefox 29.0 and above, click the menu button [[Image:New Fx Menu]], click Help [[Image:Help-29]] and select ''Restart with Add-ons Disabled''.
If Firefox is not running, you can start Firefox in Safe Mode as follows:
* On Windows: Hold the '''Shift''' key when you open the Firefox desktop or Start menu shortcut.
When the Firefox Safe Mode window appears, select "Start in Safe Mode".<br>
[[Image:Safe Mode Fx 15 - Win]]
'''''If the issue is not present in Firefox Safe Mode''''', your problem is probably caused by an extension, and you need to figure out which one. Please follow the [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]] article to find the cause.
''To exit Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.''
When you figure out what's causing your issues, please let us know. It might help others with the same problem.

Cp8 - why do I frequently get "Not Responding" message?

When I copy slides from one project to another, or if I try to apply a different theme I will get the "Not Responding" message. It happens with other functions as well but these are the most frequent issues. I have had versions 4,5,6,7, and now 8. I never had this before.
