Java applets don't work with Firefox under 32-bit mode and I must use Firefox this way. I am using Mountain Lion and the last versions of Java and Firefox available. What can I do?

I have FireFox 15 and use the Tools/Validate HTML. I need to configure it to show all the code and number the lines it validates.

When I do Edit Tools the line has options like:

         http://validator.w3.org/check?verbose=1&uri=

Where can I find a list of the options I can use in this great tool?

Hello!

I have a problem in the chat (German). An user can't install Firefox anymore. It gives the error message, not having the required rights to install. The user couldn't uninstall Firefox before but had to as it was not able to start Firefox again. The reason maybe was a addon-bar that he don't know how it appeared there.

Do you have an idea how to solve it?

Hey All,

I've tried many things to resolve this issue, but none of them seem to be working. For some time now I have not been able to see the homepage of wordpress.com with full information i.e. stats, notifications, etc. I'm running Firefox 15 on Mac OSX Lion with the following settings and add-ons. I've tried disabling the various privacy add-ons one-by-one to no avail. Please help!

Ok. So I have been reading and reading on here. There is a website that autocompeltes in my awesome bar. It will NOT GO AWAY no matter how many times I clear ALL history, delete ALL cookies, etc. There is no bookmark saved with said website. (www.axlscloset.com).

The moment I type the letter "a" in my awesome bat, FF suggests www.axlscloset.com. I have also tried the SHIFT + DELETE on my mac. It is absolutely driving me crazy. What can I do short of resetting FF?

To update, this is happening with all letters of the keyboard. For example, "w" yield www.whitehouse.gov even though I have not visited it in months. "C" yield cbsnews.com.

Again, please note no bookmarks or the like are saved. All history and cookies have been cleared.

Thanks in advance.

I have set "show my windows and tabs from last time" in "When Firefox starts" option but the last visit pages are not opened. Firefox start up with only one tab of firefox start page. As I research through this website, "Restore previous session" button (http://support.mozilla.org/en-US/kb/how-do-i-restore-my-tabs-last-time) should show in my firefox start page but it is not. Moreover, the menu History > Restore previous session menu is grey color, cannot be selected.

Dropdown lists have stopped appearing when I'm using Firefox, although it works fine in Safari (and IE on my work PC). I'm running Mac OS 10.8.1 and the most up to date version of Firefox, and the dropdown lists worked in Firefox until a few days ago. All the previous fixes for this issue appear to be based on people running Windows.

I just got a newer Mac Pro and loaded OS 10.8. Then I used the Migration Assistant to transfer all of my files, programs, and settings to the new machine (old machine was running OS 10.6.8). When I try to open Firefox, I get a Profile Missing dialog box. It says: Your Firefox profile cannot be loaded. It may be missing or inaccessible.

Does anyone know why this is happening?? If so, how does one go about fixing it?? If anyone has any ideas, your input will be greatly appreciated. Thanks in advance.

I added social networking to my accounts on mountain lion. In Safari there is a share button directly next to the address bar. I am wondering if this feature is also compatible with firefox. I can't seem to find a share button.

I am trying to achieve a one click drop down menu without side selection for "Safari". Possibly I need to drag bookmarks and folders from the "Safari" folder into the "unsupported " folder, but when I tried this it doubled everything I drug in.

I've followed directions for importing from HTML file and importing from another browser to no avail. I did get empty folders importing from another browser. Just empty folders no bookmarks.

Any assistance would be appreciated.

Thanks,

Tom

Firefox won't print webpages correctly. The pdf comes out blurry but fine using Safari browser. Apple store could not figure out what the problem is. All plugin's and java are up to date. This has happend since switching over to Mac from PC.

im an osx 10.8.2 (mountain lion) user and have recently updated to firefox 15 and am very dissatisfied with its performance. web pages lag. no fav icons. no graphics on new tab window just grey boxes. i have done much searching around and tried a few "solutions" none of which fixed any of my problems. Heck i even did a fresh install. not very happy right now

I've used Firefox for years and have the most recently updated version, but the website I created and maintain is suddenly wonky on Firefox--text out of alignment, fonts look weird, pictures overlap text. I've tried every fix you suggest--every one! The website looks fine on Safari. What's going on, and how can I fix it?

I'm trying to find the latest version of Firefox for Windows 2008 R2 for offline installation. My laptop is a Mac and the download keeps defaulting to OSX and I cannot find any link to get to the windows version.

Thanks Bob

nytimes.com keeps giving me error message 400 bad request. it loads on safari, chrome. i've got latest firefox. any suggestions?

I saw many questions like "Components.classes[xyz]" is undefined, but I have an issue with the Components.classes object itself being undefined. I have a small dummy html page where I'm trying to run a basic sample script from http://books.mozdev.org/chapters/ch08.html#77008 (slightly altered):

<script type="text/javascript"> function blah() { var c = Components; var clazzes = c.classes; // clazzes is still undefined after this line executes var myClass = clazzes["@mozilla.org/browser/bookmarks-service;1"]; // here it throws var bmks = myClass.getService(Components.interfaces.nsIBookmarksService); // call one of the object's methods: // flush the bookmarks to disk if they've been touched. bmks.Flush( ); } </script>

I've already tried running Firefox in safe mode, and it's a fresh installation of the application. Am I missing some sort of initialization?
