Firefox getting slower, not responding message regularly. Have used wisefixer to optimise system, any advice? Or just change brower.

Problem has got worse since upgrade to latest version. System hangs with message Firefox (not responding).

In other words, no fixes that require firefox to run or be open can be used. That is the problem, it will not run, but says it is running, even though it is not according to the task manager.

After my windows 7 computer did automatic updates, everytime I click on a link I get a not responding message and have to wait almost a minute for the program to continue.

Last night, my computer running Windows 7 premium home edition downloaded some automatic updates. I came in this morning to find that it had done a restart after adding these updates.
Now, anytime I click a link or do something which requires a redirect to another web page, my program gives me the not responding message and I have to wait 30-55 seconds for the program to continue.
I have Firefox 4 and it was running smoothly up until this morning, so I can only assume that whatever the automatic updates were, there is something in them that is causing this error. I do not know what updates were installed.

I don't have that problem in Firefox 29 when I read Gmail or AOL (aim''.''com) webmail. When I click on a webpage link in an email I'm reading (example: http://www.tworivertheater.org/ ) the link opens in a separate Firefox tab.
Are you saying this doesn't happen in outlook''.''com webmail and the link opens in the same Firefox tab as the email itself? I don't use outlook''.''com webmail myself. Hopefully someone will be along who does, or see [[Problems with email and how to find help]].
It might help if you would confirm the type of link that is opening in the same tab as the email you are reading in your outlook webmail. If I misunderstood your problem, please explain it better.
It might also help if you could furhish more troubleshooting information. Please do the following:
*'''For Firefox 29.0 and above''': Click the menu button [[Image:New Fx Menu]], click help [[Image:Help-29]] and select ''Troubleshooting Information''.
Now, a new tab containing your troubleshooting information should open.
*At the top of the page, you should see a button that says "Copy text to clipboard". Click it.
*Now, go back to your forum post and click inside the reply box. Press Ctrl+V to paste all the information you copied into the forum post.
If you need further information about the Troubleshooting information page, please read the article [[Use the Troubleshooting Information page to help fix Firefox issues]].

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!!!

My Firefox won't quit and gives a "not responding" message after I use Google Mail. I have tried starting in "safe" mode and the problem still occurs.

I have an issue where Firefox wont' quit and gives a "not responding" message after I have been using Google Mail. It works fine when I am not using that program. I have tried Safe Mode and the problem still happens when I go to Google Mail, so it is not connected with add-ons, extensions, etc.

Many site issues can be caused by corrupt cookies or cache. 
Clear the Cache 
'''''Firefox/Tools > Options > Advanced > Network > Cached Web Content: "Clear Now"'''''
 and 
Remove Cookies '''''Firefox/Tools > Options > Privacy.''''' 
Under '''History''', select Firefox will '''Use Custom Settings'''. 
There is a button on the right side called '''Show Cookies'''. 
If there is still a problem,
'''''[https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode Start Firefox in Safe Mode]'''''
 While you are in safe mode; '''''Firefox Options > Advanced > General'''''. 
Look for and turn off '''Use Hardware Acceleration'''. 
Poke around safe web sites and see if there is still a problem. Then restart.

When emailing from iPhoto I keep on getting 'server not responded' message.

Would anyone be able to help with the issue I have with iPhoto. Every time I try to email photos directly from iPhoto I get this message 'server not responded'. I have the lates Mountain Lion OSX installed on MBA. Also, in addition to iCloud account I tried to add two more email accounts to iPhoto hoping that this might solve the problem, but it didn't. Would anyone have any ideas what I might be doing wrong?
Thank you.

Marius,
set the mailer in the iPhoto Preferences to "Mail.app", not to "iPhoto"
iPhoto > Preferences > General
Email Photos using: Mail
This way you will be able to mail your photos directly from iPhoto, but you cannot use the iPhoto cards; use the Mail Photo stationary instead, once the mail panel opens.
For some reason mailing using iPhoto as Mailer works for me only, if I am mailing from my iCloud accoun,t and if Mail is set to use the iCloud account by default.
Regards
Léonie

Keep getting a "not responding" message. It's getting worse by the day. Nothing seems to work, including resetting.

I've been getting this message for weeks now. And this is the 3rd time I've asked for help with this and nothing is working. I'm thinking about jumping ship back to Internet Explorer. Can't believe I'm saying this since I've been with you guys for years now. Can anyone PLEASE help? Keep getting this damn "not responding" message.

When I click on the Firefox icon, my homepage opens to about 95% and then it stops reponding. If I click on anything, I get the message that it is "not responding:. I have used Firefox for years with no problems. What can I do?

I have used Firefox for years and it has been great until a few days ago. Now when I try to open it, the homepage from a few days ago opens, but the green bar on the lower right fills in about 95%. On the lower left it says "transferring data from l1.yimg.com but it freezes there. If I click on anything, it says (not responding) on the upper left. I have uninstalled Firefox twice and redownloaded it and the exact same thing happens. Please help me. Thank you, Dave Schumer

Every time anything happens on Firefox, I get a 'Not Responding' Message for around 10 - 20 seconds.

For the last couple of days, Firefox has been acting strangley. It doesn't crash and need to be closed, it is just a lot of Micro crashes. Every time I change a tab, refresh a page, click on anything, do anything, Firefox stops working for about 10-20 seconds, sometimes shorter, sometimes longer. When it happens, I get a message at the top saying (Not Responding) untill it fixes it self later.
I had been quite happy with Firefox, but if this problem can't be fixed, I will be forced to find an alternative, which I dont like the sound of. Any help would be appreaciated...

This advice did not help. What else could be wrong. This is becoming ridiculous!!!

I get a "not responding" message when changing websites or webpages.

When I change to a different web site, or go to a different page withing a website very often in the upper left corner of my screen I see the message "Firefox is not responding" and my computer freezes up for a few seconds. Sometimes it freezes up for 30 seconds. This is extremely annoying. This happens quite frequently. I have tried re-installing Firefox, but the problem is still there.

Using McAfee?

Firefox often slow, not responding and showing unresponsive script errors.

In the last few weeks, firefox has often gone unresponsive, usually shown as 'not responding.' This lasts anywhere from a few seconds to several minutes (possibly longer, but by that amount of time I loose patience and 'end task' in task manager.) This is usually followed by an 'unresponsive script' error. Which script it is varies. I've been responding by clicking 'stop script,' which usually fixes the problem temporarily.
The problem seems to occur mostly randomly, but will predictably always occur on site with videos like youtube. Here it is also worse, taking much longer to resolve if it does at all. I've got flashblock active, and sometimes the error will occur before I get a chance to activate the video and sometimes after, but will always occur. Also, on this sort of site, the 'unresponsive script' error will also go unresponsive most of the time, which I've not seen anywhere else, meaning that the only solution, after a while is to end the process in task manager. I've at times attempted to play the same video for half an hour with no success.
As I've therefore spent a fair bit of time in task manager, I've noticed that I end up with many processes running for FlashPlayerPlugin_15_0_0_152.exe*32 (Description: Adobe Flash Player 15.0 r0.) They build up the more I use firefox, but go away when I restart my computer. I've gotten up to at least 50 at one point. Most use 128 or 124 K of memory, but about 1 in 7 uses between 1-5000 K. I don't know if this is linked to the above issues, but I've only noticed it since it started.
I've tried resetting firefox and it changed none of the above.
If it helps, I used Windows 7. Feel free to ask for any more details about my system and I will do my best to answer, though I'm not an expert in computers. Thank you very much in advance for your help.

Thanks for the advice. What solved it was disabling all addons and then restarting the computer. I've since reenabled Adblock (2.6.4) and Flashblock (1.5.17) without causing the problem to reemerge, leaving Troubleshooter (1.1a) as my only previously enabled addon I've not reenabled. I am no longer experiencing the issue.
Regarding updating to version 32, I tried this, but the official site told me I already had the most up to date version of firefox for some reason. Normally, it updates automatically. However, as my issue has been solved I don't consider this a problem.
Thank you very much for your advice.

Why does firefox hang or not respond when I am using disable third party cookies setting

I have, by process of elimination, realized that when using the setting "allow third party cookies - 'never' ", causing my firefox to hang so much that I cannot use it. I have used that setting "allow third party cookies - 'never' ", for as long as it has been available. Over that last few months, I have been having problems with firefox hanging and getting the message "firefox not responding". It became very annoying, causing me to look for a solution. I read through the kb and tried many solutions. I can now say that when I change the cookie settting to "always" the problem goes away. It is helped only slightly by using the "from visited" setting. How can I fix this? I don't want all the cookies but I cannot surf with this problem constantly.

The problem is that "third party" includes both related servers and advertising networks; the setting is too crude to accomplish the objective of blocking tracking cookies that you don't want.
My compromise is to accept all third party cookies, but set cookie lifetime to "Keep until: I close Firefox." As a result, tracking is limited in time, even if during any given session I can be seen on different sites. (I also use the NoScript extension, so many ads driven by scripts never load.)

Copies of e-mails repeatable being downloaded and when I try to delete them it is very slow (I get the not responding message) how can I cure this?

the question covers most of it. I will add that this suddenly has started to happen and I have not knowingly made any changes to my system. The e-mail address is a secondary one to my main address which is a btinternet.com account
