Please provide some specific direction for this error message. This message happens each time I attempt to launch Firefox. If I click restore, it will load Firefox. But to do this each time is very bothersome.

I am having trouble getting Java to work in Firefox (Opera too) on Mac. http://www.java.com/en/download/installed.jsp?detect=jre tells me "We are unable to verify if Java is currently installed and enabled in your browser." Notice that when I access the page, Firefox wants me to activate Java in a pop-up. I did this.

I know that Java is installed because I can open the Java Control Panel. The setting "Enable Java content in the browser" is checked and Security Level is set to High. I have tried setting the security level to a lower setting, but that doesn't help.

I have verified that the Java plugin is enabled. I have tried clearing Java cache via the control panel - no luck.

I realise that Apple has blocked Java according to this article: http://appleinsider.com/articles/13/01/31/apple-again-blocks-latest-version-of-java-through-os-x-anti-malware-system. I have been able to get Java to work with Safari (this doesn't help for Firefox) by editing the file /System/Library/CoreServices/CoreTypes.bundle/Contents/Resources/XProtect.meta.plist, but that is only a temporary solution, as it shouldn't be necessary to do this edit.

Whenever I start Firefox I get the following message:

"Well, this is embarrassing. Firefox is having trouble recovering your windows and tabs. This is usually caused by a recently opened web page. You can try: "Removing one or more tabs that you think may be causing the problem "Starting an entirely new browsing session"

Problem persists when relaunching FF in safe mode. Problem is temporarily solved by resetting FF, but repeats and persists after navigating to any page (such as wikipedia.org), closing all tabs, quitting FF, and relaunching FF. FF pref "When FF Starts" is set to home page by default, and FF home page is set to Mozilla FF start page by default. Changing this pref "Show Blank Page" has no effect on the behavior.

Mac OS System Pref "Close windows when quitting an app" is ticked (by default). Unticking this box does not change this FF error.

Im using firefox 20 beta and os x 10.8.2, Ive been on beta channel for a long time but with 20 beta every time I start firefox it says "well this is embrassing..." and tries to restore couple of tabs I visited before..problem just started after first update of beta ,

I tried; reset firefox complete uninstall by deleting profile folder also deleting org.mozilla.firefox.plist file in preferences folder in library

made clean instal but nothing changed. Im sure firefox closes normally as I checked on activity monitor and my homepage is about:newtab. "show tabs from last time" is not selected from preferences.

same problem continues on aurora 21 too, it just started after first update of 20 beta, I used 20 beta without such problem for a week, but since first update of beta its broken even on aurora too.

btw java is disabled and problem occurs when flash is not working..

In managing the files on the a website my company runs, we updated a high-res pdf for download. Firefox is not reading the transparencies correctly, and every other we browser is views them fine. There are either changing the value, or in some cases, the color the pages show up in.

Any suggestions why Firefox wouldn't be reading the transparencies in the pdfs correctly?

I'm getting a strange behaviour in Firefox 20 that I don't see in Firefox 19, but that I can't really find a source for. It's largely repeatable for me, but it's not easy for me to reproduce in other settings.

In essence, I can end up with a select that I can open, but when I click on an item in the selector, nothing happens. Javascript events don't seem to fire, it's just like the item can't be clicked. Once this happens, I can close and re-open firefox and repeat the behaviour as often as I like on the same drop-down. I was able to reproduce it with a simple test case here: http://jsfiddle.net/codiform/LgvRb/8/

But, strangely, I wasn't able to reproduce it with a local HTML file; not sure if that's relevant, or perhaps I just failed to exactly reproduce the scenario in some way, because it's not clear to me what the trigger is.

If i reload firefox in safe mode or reset firefox (in the --safe-mode dialog), this problem will go away for a bit, but it will come back. I have not yet been able to reproduce this when I don't have the Google Web Toolkit (GWT) plugin installed, but that may simply be because I'm trying to use firefox for GWT development, and when I can't trigger the behavior, I go back to doing development work until I the problem recurs. I don't know for certain that it can or cannot be reproduced without the plugin.

Although now that I think of it, I should try removing the plugin now that the problems back and see if it will make the problem go away again. That won't guarantee that you don't need to install the GWT plugin to make it occur, of course, but it'd be one more piece of data on reproducibility.

After updating to FF 20, the Google.com homepage is missing the black menu bar at the top (listing news, gmail, etc.). No problem in Safari, the bar is there. Missing only in FF.

This code work in explorer, crome, omniweb and safari but not in firefox. I have also tried on other computers.

Is there anyone who can explain what I do wrong?

Despite making sure I have the current Silverlight update installed, I've been having repeated trouble trying to view videos on Mac OS Lion. The crashes consistently happen whenever a link to a Silverlight video is clicked. Crash ID is bp-caa5b831-2464-47a6-9c0a-09f112130513.

The the website cnnsi.com http://sportsillustrated.cnn.com/baseball/mlb/gameflash/2013/05/14/48008/index.html#recap

The scores of baseball games are shown across the top. Normally when I click on the scores of a game a page is opened and I can read the recap of the game or game summary. But since three days it just shows black screen with text LOADING...... and the page never loads.

I tried the same link in SAFARI and it works just fine.

What is the fix , please??? Thanks RB

When I check my plugins, the following three, very closely related (in my mind) plugins are listed, and the "Renderer" still shows "Research" when checking to see if it is Up-To-Date. It seems to me I don't need all three. I tried removing the Renderer (yes, I know how to do that safely), but Google seems to continue to reinstall it (with one or both of the other two...?)...I'll ask this on a Google Forum too, since it's their product, but wondered if anyone has any insight. I obsess about plugins that need "Research" - Thanks!

for instance, a search for chris niemczyk gets me his pics but when i click on one, i get this page:

The previous page is sending you to http://emfan18.tripod.com/niemczyk.htm.

If you do not want to visit that page, you can return to the previous page.

i just want it to go straight to the page or else i wouldn't have clicked on it in the first place. it's google. of course it's going to redirect me!

I recently updated to Firefox 20.0 and noticed that the native Inspect Element tool doesn't have an option to display the page css elements along the right-side of the window like it used to. Is there a button somewhere I'm missing that allows this view?

I also noticed that I cannot hit escape to exit the inspector anymore. Why would this option have been removed?

Screenshot of the issue explained a little better... http://exceptionalsheet.com/error.jpg

I tried to right click on bookmarks in "Bookmarks Toolbar" which are "Inside a folder" or under "Show more bookmarks" to delete or rename them but nothing happened! like i didn't right click at all

but if a bookmark in Bookmarks Toolbar is not in a folder and is not under show more bookmarks its ok and i can right click o manage it

Now to delete a bookmark inside a folder i have to drag it outside and then right click and delete it or use bookmarks library, which is really annoying, shouldn't we be able to right click on bookmarks inside folders and delete them there?

Is there any shortcut key for example holding command and clicking to rename or delete a bookmark until this bug is fixed?

Hi Every time I open a PDF invoice in the built in PDF viewer - in Firefox Mac - I have to resize the the window and zoom the page to see what's on it. Is there a way to set a default window size that suits me better?

I have a very annoying problem with a website that I have uploaded to a hosting server. When I try to view php pages with Firefox in Windows from the server all it says in the browser is "The system cannot find the file specified.". It had been working for years before this and I have not changed anything on the server.

When I use the same link in Internet Explorer, it will load the page. I cleared the IE cache to make sure that IE was not storing it somehow as well and it still worked fine on IE.

It works fine in Firefox 21.0 on Windows XP but fails on Firefox 21.0 on Windows 7. In both cases we have Flash version 11 installed.

I have tried googling that error message but it seems to usually be related to windows files missing etc. and I couldn't not find anything specifically to do with Firefox not loading a page.

Example: http://www.healthclips.com/01-cardiology/01-angina.php

I can view a page regularly, like everything is normal until i go to log in. I get a blank page as soon as the page loads, and this happens to many websites. Ive tried searching in safemode, editing my firewall settings, removing cookies, disabling plug-ins, clearing history/cache, but i've had no luck so far. Anyone have any solutions ? I notice that every page i load includes ".php" in the URL bar. Thanks in advance

This seems to be a common problem. Firefox fails to open PDF files. It just shows a blank white screen. The common solution is to shut off the Adobe Reader add-on. Well, it didn't work for me. PDF is still not loading.
