I cannot get PDF files to open for viewing in Firefox. I am on Mac OS platform. This seems to be such an ongoing issue. I have followed the troubleshooting procedures to no avail. I like the look of Firefox better than Chrome, but I am switching over to Chrome because PDF's are so much easier to handle on Chrome, and I am sick of wasting time with this. Any last minute tips or advice?

MacBook Pro 8,2 with OS X 10.6.8 4GB RAM 2GH Core i7 Firefox 20.0 Shockwave Flash 11.7.700.169 Hardware acceleration enabled. Flash player plugin often starts at 40% to 60% of CPU but sometimes slowly builds up to where Activity Monitor is showing close to or even over 100% of CPU effort. Processors heat up and fans run at over 4,000 RPM. Video begins to drop frames and may eventually stop. Only solution (but not good) seems to be to either kill (force-quit) the Shockwave process or quit/reopen Firefox. I suspect there may be other things using the Shockwave process elsewhere on the web page and/or on other tabs that I can't find. (Running Shockwave player in Safari seems to use much less CPU effort. Even when I play two full HD videos at the same time, it only uses 60% to 80% of CPU in Safari.) Is there another video player that I can use in place of Shockwave Flash?

I have my system set to minimise windows by double-tapping/clicking them on the title bar. It works for most of windows (iTunes being exception). It's a system preference thingy, so it should work across all the board. After the recent update to 21.0, my Firefox is unable to minimise by double-tapping on the title bar anymore. Is there anyway to fix this issue, or will this be solved in the next update?

In Firefox 21 for Mac OS, there is no longer any preview image, which is usually a little screenshot of the left end of the toolbar, shown for a theme when you click the "More" link to get more information about the theme. The only image there now is the theme icon. Where did that preview go and why is it gone? The preview images are still in the .jar files in all the themes I have, so they are still available.

I have added the following code to my userChrome.css file, but favicons pop up again when I download files (documents, photos, etc). How can I get rid of favicons completely, so that they don't reappear after a download? Thanks!

 */
/* Bookmarks Toolbar - hide favicons/placeholders for sites, but show folder icons for menus */
#personal-bookmarks toolbarbutton:not([type="menu"]) .toolbarbutton-icon {display:none !important;}
#personal-bookmarks menuitem .menu-iconic-icon {display:none !important;}

/* Bookmarks Menu - hide favicons/placeholders for sites, but show folder icons for menus */
#bookmarksMenu menuitem .menu-iconic-icon {display:none !important;}

#PlacesToolbarItems .toolbarbutton-icon {display:none!important;}

Before I changed internet service providers, I could type my search queries into the url bar and receive search results from Google. After I switched ISPs, my queries typed into the url bar are put into my new ISP's horrible search engine. How do I change it back?

I've already tried going to about:config and changing the value of the keyword.URL preference to "http://www.google.com/search?ie=UTF-8&oe=UTF-8&q=" but that didn't fix my problem.

New information since creation of the post:

My ISP is Optimum. I have opted out of DNS Assistance and still have seen no change.

When my search term is two words or more, I am directed to Google search results. If my search term is only one word, however, I am still directed to Optimum's search results.

The Logitech mouse is a Logitech Anywhere MX Dark Field with Logitech Control Center for Mac OS X v3.6.0. I'm using Firefox 20 in Mac OSX 10.6.8. The problem has only been detecting after updating the browser to version 20. I have not customized the Back key on the mouse for any other function other than returning to previous page. Same configuration and Control Center version was being used before with Firefox previous versions without any issues.

I responded to a Firefox email which resulted in my changing my theme by mistake. I wanted to change it back. That was about three hours ago. I tried to login to my account using the username, email and password I had written down for Firefox. They weren't recognised. I asked for a password reset. No email arrived on either of my email accounts. I checked the junk folders. I requested to register a new account on Firefox. I was told an email would be sent. No email has arrived. All I want to do is change the theme back to what it was because I can't read my tabs or horizontal menu items because of the colour scheme. I've read several troubleshooting suggestions but none seem to properly apply.

I am currently using Firefox version 18.0 yet when I open Firefox, I always get this pop up message: “This version of Firefox is not supported by Norton Confidential. You will not be protected while browsing the Web. Norton Confidential cannot protect you while you use this version of Firefox. Phishing Protection requires Firefox 1.5 or later.” Do you know what is causing this? This started when I updated to Firefox 16.0.2. Am I at risk?

When I open Firefox I cannot get the default Firefox Start Page since the update to Firefox 20.0 . I have used the Firefox Preferences Restore To Default option but it refuses to work

I just installed Firefox 21. I do not see the Clear History item in the Tools menu any more. Is there any way to get that back? I prefer to have easy voluntary control over clearing the history and other data. Why did the developers not set the item in the Privacy panel to ask first before clearing anything, the way it did before?

I tried to complain about something on the "makes me sad" Feedback page. When I clicked the button to submit, I was informed that that is forbidden. I did not see any word counter any more, and my message was not very long anyway. What is the problem with that site?

When I open the Firefox application, I almost always get an error page that says:

"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"

Since before quitting Firefox I always go to "Tools —> Clear Recent History…" and have ALL the items checked when I click OK, there is no page to restore so Firefox shouldn't be having a problem. And yet…there's that window AGAIN!

This started after the last update you provided.

We have a staff computer that was recently used to check a hotmail account, this is against our company policy. The hotmail account owner says she didn't log into her account through the office computer as she wasn't even in that day. Is there any way for us to verify the length of time that she was or was not visiting this site? As our computer's history clearly shows that the hotmail account was visited. Any help would be most appreciated. Is there a way to lock company computers so that only work sites can be visited?

als ik met het kruisje een nieuw tabblad open. opent firefox sinds gister automatisch bing. ongevraagd. dit wil ik uitschakelen en gewoon google instellen als ik een nieuw tabblad open. hoe doe ik dit? tevens wil de site van bing totaal blokkeren. hoe doe ik dit?

I am sick of always getting this message when I put Firefox on when is it going to be sorted out so that it doesn't happen. I have moved lots of things over to Safari but I have always used Firefox and been happy with it up to now. Please can somebody sort it out.
