Firefox will crash and say NOT RESPONDING at random. This happened when I updated to 6. I don't want to have to break into my system to make it work when Firefox 5 and under worked fine.

Just suddenly 3 hours ago, letmewatchthis.ch stopped working for me "Unable to connect

         Firefox can't establish a connection to the server at www.letmewatchthis.ch.
       

 The site could be temporarily unavailable or too busy. Try again in a few
   moments.
 If you are unable to load any pages, check your computer's network
   connection.
 If your computer or network is protected by a firewall or proxy, make sure
   that Firefox is permitted to access the Web."

All other sites are fine and I have used letmewatchthis over 1,000 times. I ha it tested on a few on the test sites and apparently it is just me :/

I tried to install Moonlight plugin version 3.9.9 (4 preview) on the latest version of Firefox. Error message is: "Novell Moonlight could not be installed because it is not compatible with with Firefox 6.0.2". There isn't any versions of Moonlight that can be installed on Firefox 6.0.2. Moonlight plugin worked very well with previous versions of Firefex.

Is it correct? When Firefox 6.0.2 will become compatible with Moonlight plugin (or vice-versa)?

Running OS X Lion 10.7.1 Mac mini early 2009, 4GB RAM. No other problems except both Firefox and Chrome are incredibly slow opening web pages when compared to the same two browsers in Windows or to Safari in OS X.

This happens whether other applications are running or not. Internet speed has not changed (tested 6 Mbps), not using proxies, etc. Yes, I did test after Quitting all other apps. It makes no difference.

I don't care for firefox updates, trying to be bigger and better than the competition, I get it. However, each update is 100% incompatible with Java and in case the individuals who collaborate and makes such updates are unaware, the entire world wide web uses Java. Why would anyone want to use firefox when they can't even use the internet?

Firefox keeps locking up. Downloaded latest version mid Sept. Since then get not responding many times. I reloaded older version of Firefox but that didn't seem to help. Almost everytime upon loading, then starting to enter a search name a box comes up with s04.cltrda.com/sc?p....... many more characters on the address totaling over 100. What is this? How do I get rid of this? Al

Norton 360 popped up a "file insight" message related to a file that was downloaded to my PC. The source file was Firefox.exe, and the name of the file is RadioWMPCoreGecko19.dll Some sites are reporting this file as malicious, but it seems to me that it is a plugin extension for firefox? Can you explain this file to me?

I recently added Firefox as a second browser to the Internet Explorer 8.0 that I have been using. During the download of the Firefox browser, I thought it was transferring my Favorites List of most frequently visited websites. I cannot find this list anywhere when I use the Firefox browser. to access the list I must use IE 8.0. Please advise because i rely on access to this list in my daily work.

After I upgraded to Firefox 7 (and 7.01) the Divx web player controls were not available when playing a Divx video on a website and the menu did not come up when I right-clicked on the video. I tried different versions of the Divx web player, including the latest, and the problem remains the same. Also, the video would only play but would not download automatically to the cache in the Divx movies folder on my computer while it was playing like it did before. I have re-installed Firefox 6.02 and everything works fine again.

Up until Version 6.0.2 FF supports the following command via the address bar "javascript:window.resizeTo(1280,1024);". In version 7.0.1 and in the beta version 8 - this is no longer supported. I use this all day in my role as a project manager to test web pages in different screen resolutions and I've had to downgrade back to 6.0.2 just for this feature.

Has the support for this been withdrawn permanently or is there a way to enable it in v7 or v8?

Thanks.

if I upgrade FF 6.02 to 7.0 or 7.01 Fast Dial opens as a blank page. I upgraded Fast Dial from 3.4 to 3.51 and no difference. Anyone else having the same trouble? I had to down grade to FF 6.02 again so that it would work. Have not found an answer in FAQ or troubleshooting

After the upgrade to Firefox 6.0, a kind of malware has been included in the browser. When opening, i.e, a newspaper site, some words appear as double underlined, and a link to www.textsrv.com/xxxxxx is included as hyperlink. I wanted to extract this pluging, malware, or whatever it is called unsuccessfully. Looking into the internet, it seems that the Adobe Flash has the problem. ¿How do you recommend to solve this issue?

Please help, Marianne Hart

See, for example, http://techdows.com/2011/09/removing-avg-secure-search-as-search-engine-in-firefox.html. Since it's hijacking a Mozilla product, Mozilla's apparent indifference is baffling.

26 Sept. 2011 I get the dialog box mentioned in the Question when I click to open Firefox. I click OK button in dialog box and Firefox opens/launches. I installed Java around the same time I installed Firefox. I installed Firefox and Java within the last seven days. I have a screen shot of the dialog box.
