I later downloaded the Active X version 11.1.102.63 but the same thing keeps happening,its impossible to watch movies or tv shows,my yahoo email is non functioning because of continuous plugin crashes,Cnn Youtube the same problem,any site that uses flash content just the plugin crashes,its non stop. Windows XP Professional Service Pack 2 32 bit,1.80 GBz,224 MB ram Avast free version 7.0.1407 Firefox 11

If I restart my browser everthing works just fine for at least 5 minutes. When I watch several youtube videos, the lag comes back and the video starts to freeze aboud every second for just a faction of a second. The sound is stil played properly it only affects the graphics... After about 10 minutes watching videos the whole browser gets laggy . Sometimes when I type the fonts appear only about a second later. Scrolling is also affected. Some minutes later everything is back to normal but it't not allways like that?!

I don't know what to do, I allready restarted with add-ons disabled but I didn't notice any difference. The drivers of my ati graphics card are up-to-date and I only have the problem with firefox, chrome works perfectly.

I just installed Firefox 12 and memory usage on 40 open tabs spiked from a maximum of 900 MB-1 GB to 2.5 GB. Memory usage for firefox.exe would start at 4-500 MB, steadily increase to 2.5 GB in 10-20 min even if I did not touch the browser at all. Hard drive I/O went trough the roof as well. Laptop would become unresponsive and Firefox would eventually crash. Downloaded Firefox 11, installed it on top of Firefox 12 and everything is back to normal, memory usage is less than 900 MB with normal usage, it doesn't really grow past that. Guess will stick with 11 until they fix these issues in 12.

I picked up a Yahoo Search functionality inside Firefox but there was no Yahoo toolbar. I ran Revo Uninstaller and there was no listing for Yahoo. I ran Add/Remove Programs in the Control Panel but there was no listing for Yahoo. However, in my Programs File under My Computer there is a folder titled Yahoo.

Whenever I opened Firefox I would get a Yahoo Search page instead of Google. I did a bunch of searches for solutions and found that I needed to delete all of the search listings in the drop down list from clicking the gray arrow in the search box.

They were all in there – Google, Yahoo, Bing, Twitter, and an odd entry called “Search Here” I deleted everything except Google. Then I went to about:config and reset the Keyword URL to the Google entry it was supposed to be.

I thought everything was fine but all of this left me with some strange Search Here window next to the Firefox Tabs and the same Search Here entry in the drop down list previously changed.

If I perform a search from the search window next to the open tabs I get a Yahoo Search result:

If I perform a search from Google I get a Google result as I should.

Interestingly, the Search Here listing appears again automatically in the listing of search engines.

I use Firefox constantly. I'm now on version 11 but not much has changed. I've been forced to disable most every plugin and extension trying to troubleshoot my issues and I still have the same problems. No matter what site(s) I'm on after 2 or 3 clicks I get the running circle and the browser freezes. If I click again, I get the "Not Responding" message in the top bar. Most of the time it recovers within 30 seconds to 2 minutes and I can continue. Very often the whole thing freezes with no message but before long I get : Script: resource://gre/modules/XPCOMUtils.jsm:331 or Script: resource:///components/nsPrompter.js:466 and neither seems to be attached to any plugin or extension. No matter which version I've used and no matter what site I'm on this happens. I've decreased my allowed scripts to run time to "20" and disabled everything including hardware acceleration. ALSO, about 50% of the time when I'm editing my own site, all of a sudden it becomes VERY sluggish and takes too much time to do anything. When this happens I've switched right over to IE9 and have none of these issues. I also have an error log as long as your arm. Troubleshooting information is below. Please help!

Receiving browser setting change error message about every ten minutes.

"An unknown change was detected on your browser's search settings" There are two options to check. 1- Keep your current settings. 2-I am aware of the changes & approve it.

I can select either option and then click on the yes button, but the system does not respond. It will not let me close the window by clicking on the X in the right-hand corner. The only way to delete it is to close the window on the task bar

Как известно появилась поисковая система "WEBALTA", которая автоматически стала стартовой страницей. Попытки установить "Яндекс" на стартовую страницу оканчиваются провалом. Прошу вас решить эту проблему, поскольку я и члены моей семьи предпочитают использовать "Яндекс" (более привычный и удобный для нас способ)

Previously, I had no difficulty w/ downloading pdfs. Now all I get is a blank Firefox screen, with nothing else happening--no downloads window opening up like before, or anything else. I recently upgraded my Adobe Acrobat to 10.1.3, and I wonder whether this is related to that? Does FireFox not find the new Acrobat? I've gone through the things on the Firefox help page like changing download folder and renaming the whatever folder it was from what: rdp? to rdp.old. Does not effect problem.

Some video I can not watch. This is an example: http://vk.com/video_ext.php?oid=-22692421&id=162777880&hash=32fbd5ce2453bf2b&hd=1" width="607" height="360" frameborder="0"></iframe>

Since the Google toolbar has continued to work on my wife's computer when she upgraded to Firefox 11, I decided to upgrade. It worked for a while and then disappeared. Could the difference be that she is using Windows 7 and I am using Windows XP? Thanks

On my home computer, a fresh Firefox 11 install has the 3D button, but on my work computer where I just upgraded from 10 to 11, the button is not there.

Are there some prerequisites for the 3D DOM inspector that I don't know about? Is there a way to find out why it's not showing up, or to forcibly enable it?

I just recently updated my Firefox and right after I did that I had Facebook, Wikipedia, and some other sites feature ads that say "Ads not by this site" written under them! How do I remove those? Help!

I have the latest version of Firefox and the latest version of Adobe Flash Player and now no videos will run. I don't know what to do. Flash Player was running fine on Firefox 8. I shouldn't have upgraded. It has affected my Yahoo email and Facebook pages as well.

This was solved a long time ago. I previously flagged it as solved. I continue to get suggestions.. I don't need them. I've tried "unsubscribe" too, but I still get answers. NO FURTHER ANSWERS ARE NEEDED. Thank you. recently Firefox installed a search bar in line with my tabs. I don't want it and can't find how to get rid of it.

Hi I tried to reinstall flash player........I install via plug-in finder but it failed....and I also tried to install flash manually.....but firefox still cannot find flash player plug-in and cannot play any youtube video and flash games
