PDFs do not load in Firefox, they do when I'm in Safari. If I'm on a website and I click on a pdf link, nothing happens. It has happened from multiple sites.

PDF files do not load in Firefox. I click on a link for a PDF and nothing comes up. It happens at every website. I've been using Safari because PDFs open up there just fine. I have all the updated plug-ins, etc. and checked to make sure everything on Firefox was updated. I'm on a MacBook Pro, 10.7.3. I've never had this problem before.

I am having the same issue - also on a macbook pro, also turning to Safari. I just get a blank page - no download initiates, nothing happens.

Background CSS images not loading in firefox when using a CDN

Hello,
I am having trouble getting CSS background images to load in Fire fox when using a CDN.
Here is a description of the problem:
- Everything works fine in Chrome
- Any images loaded through CSS do not load in Firefox (they load in chrome) when i have the CDN enabled.
- Other images / custom fonts appear to load fine with the CDN enabled
My setup:
- wordpress 3.8
- CDN - Rackspace Cloudfiles synced with w3 total cache plugin (using the 'origin push' configuration)
- using Cloudflare (mozilla appears to load the site fine while cloudflare is active)
More about the problem--
I suspect that the problem has something to do with the htaccess file redirecting some urls or something-- but im not quite sure what to do about this.
Has anyone encountered this problem before who can offer some insight?
thanks

Hi pvijeh, is that the explanation for a security error? I'm having trouble understanding the context.

I use Safari as my browser. When on a site and I click on a PDF file I get a black screen and a notice that "Adobe Reader blocked for this website". However, this does not happen if I use Firefox.

I use Safari as my browser. When on a site and I click on a PDF file I get a black screen and a notice that "Adobe Reader blocked for this website". However, this does not happen if I use Firefox.

Back up all data before making any changes. Please take each of the following steps until the problem is resolved.
Step 1
If Adobe Reader or Acrobat is installed, and the problem is just that you can't print PDF's displayed in Safari, you may be able to print by moving the cursor to the the bottom edge of the page, somewhere near the middle. A black toolbar may appear under the cursor. Click the printer icon.
Step 2
There should be a setting in its preferences of the Adobe application such as Display PDF in Browser. I don't use those applications myself, so I can't be more precise. Deselect that setting, if it's selected.
Step 3
If you get a message such as ""Adobe Reader blocked for this website," then from the Safari menu bar, select
Safari ▹ Preferences... ▹ Security
and check the box marked
Allow Plug-ins
Then click
Manage Website Settings...
and make any required changes to the security settings for the Adobe PDF plugin.
Step 4
Triple-click anywhere in the line of text below on this page to select it, the copy the selected text to the Clipboard by pressing the key combination command-C:
/Library/Internet Plug-ins
In the Finder, select
Go ▹ Go to Folder
from the menu bar, or press the key combination shift-command-G. Paste into the text box that opens (command-V), then press return.
From the folder that opens, move to the Trash any items that have "Adobe" or “PDF” in the name. You may be prompted for your login password. Then quit and relaunch Safari.
Step 5
The "Silverlight" web plugin distributed by Microsoft can interfere with PDF display in Safari, so you may need to remove it, if it's present. The same goes for a plugin called "iGetter," and perhaps others — I don't have a complete list. Don't remove Silverlight if you use the "Netflix" video-streaming service.
Step 6
Do as in Step 3 with this line:
~/Library/Internet Plug-ins
If you don’t like the results of this procedure, restore the items from the backup you made before you started. Relaunch Safari.

TOC, Index, Search content not loading in FireFox 3.0 +

Hi,
I have created from RH 8 a merged Webhelp system (1 master, 2 children - based on Peter Grainge's posted procedure). It works fine from IE, and on my system, from FireFox 3.0 and up.
The problem is, that when deployed at the customer's site, the TOC, Index, and Search content does not load in FireFox. All frames display (Nav, contents, and the top frame), but the content for the TOC, Index, and Search does not load.
This only happens at the customer site. The webhelp system works okay in IE.
I have checked and we are running the same javascript version, have the same security settings in FireFox set.
I looked on Peter's site and implemented the redirect fix for FireFox that he has posted, but that hasn't seemed to fix the problem.
They aren't running any special toolbars (like Google toolbar). I am checking on add ons.
Does anyone have any ideas on what else I might check or better yet what might be causing the problem?
Thank you,
Tannis

A merge will not work properly unless all the projects have been generated once. After that it should not matter that a project is missing, indeed simply not publishing one of the projects to the server is one of the features of merging making it easy to supply different customers with different content.
I wonder if the problem you saw was because that project had not been generated.
Tannis
Sorry, the reference to AIR help was because you mentioned Snippet 141 which is AIR specific. I didn't look further back in the thread.
You said that the start page of a child project opens the tripane window with the default topic but you do not get the TOC etc. That rules out the merge being the problem. I am inclined to the view that the server is the issue so get your client to load the published output from my merge demo as that is a known quantity. Ask them to open each child project in turn and then finally the merge.

Facebook activity feeds do not load in Firefox 9.0.1 Mac

The facebook social plugin activity feed found on this page:
https://developers.facebook.com/docs/reference/plugins/activity/
does not load in Firefox. I see the feed when I open web pages in Safari, but I get a blank space in Firefox.
Below is one example of a website (in the bottom of the blue right bar) where there is a blank/white space instead of a feed. This is happening on multiple sites... in fact I cannot find an example of where the FB activity feed is working properly in Firefox.

I have a Flash slide show on the home page of my website that has stopped working in FireFox 8.01. The Flash movie plays fine in other browsers and on PCs running FireFox, but not on either my MacBook or iMac running FireFox 8.01.
Works fine on my Brother's Mac running Firefox. But not on my 2 machines. VERY strange. I have reinstalled everything I can think of.

Farmville will not load using Firefox, but it will with IE, for over a week now.

Farmville will not load using Firefox, but it will with IE, for over a week now. I have cleared the cache and cookies multiple times, updated flash player, did a virus and malware scan, allowed java script, allowed mozilla in the Windows firewall, contacted Zynga multiple times, and yet Farmville still will not load using Firefox, my main and preferred browser. I'm very frustrated and want this fixed.

Thanks for the advice cor-el, but if you would read the info I posted, I already did that, SEVERAL TIMES. That's not the solution unfortunately.

Mailbox will not load in firefox 4

The tiscali mailbox will not load within firefox 4. I am able to log into the mailbox but once logged in I cannot access the inbox or any other function apart from email composition. Attaching a file to an email also produces a 500 error within the upload window.
I have contacted Tiscali/TalkTalk support and they have directed me to you as they claim it to be a browser issue. I have no problems with this website in IE or in Firefox 3.
I have not been able to solve the problem by disabling all addons.

anyone?

Fash Images will not load with Firefox

Currently Flash images will not auto load with Firefox on my mac 10.4. All flash images show with an arrow I must click to make them appear every time I visit a page.
I do have the most updated version of Flash (10.2.152.33). I have checked their site for all troubleshooting possibilities as well as the FF forum & nothing has made these images auto load. I do have load Images automatically in my Preferences: Content. This is only happening with Firefox & not all browsers.
I do remember having to add some Security: Install Add-On Exceptions a few updates back in FF back when I had this problem. Adding them fixed the problem, however the next update made the issue reoccur. I've looked for additional exceptions & possibilities to include & found nothing. My current list of add on exceptions include: addons.mozilla.org, getpersonas.com, & update.mozilla.org. Removing these does not fix the problem & re-entering them does not fix the problem. All flash images still show as arrows that must be clicked to load to view for my Firefox browser only. This does not occur in any other browser.

alright. I've found that Firefox has a Flashblock setting & I have found a way to disable it if I customize & add an icon to my toolbar however I would like to learn how to change that setting without having to add that icon. Where in the settings does it allow me to change/adjust the flashblock?

Google Play tab not loading on Firefox

Hi,
Ever since I updated to the current version of Firefox, the 'My Library' tab on Google Play does not load properly. I have been in touch with their help desk, and have tried multiple steps, including:
1. Clearing cache and history.
2. Uninstalling and reinstalling Flash player
3. Uninstalling add-ons from Ad aware and AVG Antivirus
4. Disabling and reanabling add-ons from the Add-ons Manager, while only enabling Flash Player
5. Uninstalling and reinstalling Firefox.
6. Launching Firefox in Safe mode
None of these fix the issue. If it were a problem with the Flash plugin, I would expect none of the tabs to work. But it's only that single tab that does not load on Firefox. These work well on IE9. At this point, I do not know of any other steps to troubleshoot the issue. Any help would be greatly appreciated.
Thanks
Prashanth

Amit,
All my plugins (Flash, the one that matters) is upto date. I tried disabling all other plugins on both laptops, but it doesn't help. I would assume that an outdated plugin would cause issues on any browser, but this seems to be Firefox specific.

A URL will not load in Firefox (it does nothing) but will load in Safari; some other URLs also have a similar problem.

In Safari with the above website, I cannot "View Source". Also, I have the same problem viewing images of patents at the USPTO, again probably a similar problem. Perhaps the web address isn't HTML but is an image format not supported by Firefox. Perhaps there is a plug-in or add-on that will be able to read the image, but should probably be included in the main Firefox release since it seems to be fairly common.

A twitter widget on my website will not load in firefox but will load in every other browser I've tried. I have tried several versions of firefox. Here is the code I am trying to run:
<code>
new TWTR.Widget({
version: 2,
type: 'profile',
rpp: 5,
interval: 6000,
width: 'auto',
height: 265,
theme: {
shell: {
background: '#333333',
color: '#ffffff'
tweets: {
background: '#000000',
color: '#ffffff',
links: '#4aed05'
features: {
scrollbar: false,
loop: false,
live: true,
hashtags: true,
timestamp: true,
avatars: false,
behavior: 'all'
}).render().setUser('ShawnC4Real').start();
</code>
And the first thing I checked was that scripts were enabled.

The scroll function on my mousepad is disabled when viewing a pdf file in firefox version 5.0. The scroll works on the pdf, but not on the other tabs. When the pdf is closed, the scroll function returns to normal. Any ideas?!

Hey thanx for the help, it worked like a charm.
I think firefox changed the application lay out, as I used to be able to choose my PDF opener from the list at " Adobe Acrobat Forms Document' where I could choose Nitro-PDF reader, but it has now moved all the way to the bottom like you suggested to the obvious place of "Portable Document Format" section.
If someone didn't tell me , I wouldn't have scrolled all the way down to be able to find it... it really should be with all its cousins up the top...
Cheers again..

Angry Birds Friends on Facebook will not load in Firefox, just white screen. Will load using Chrome, etc?

Hello,
Try disabling graphics hardware acceleration. Since this feature was added to Firefox, it has gradually improved, but there still are a few glitches.
You might need to restart Firefox in order for this to take effect, so save all work first (e.g., mail you are composing, online documents you're editing, etc.).
Then perform these steps:
*Click the orange Firefox button at the top left, then select the "Options" button, or, if there is no Firefox button at the top, go to Tools > Options.
*In the Firefox options window click the ''Advanced'' tab, then select "General".
*In the settings list, you should find the ''Use hardware acceleration when available'' checkbox. Uncheck this checkbox.
*Now, restart Firefox and see if the problems persist.
Additionally, please check for updates for your graphics driver by following the steps mentioned in the following Knowledge base articles:
[[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]]
[[Upgrade your graphics drivers to use hardware acceleration and WebGL]]
Did this fix your problems? Please report back to us!
Thank you.

Videos will not load in Firefox only. Have reinstalled, restored, etc.

Videos (from YouTube, Facebook, websites, etc.) will not load in Firefox. I've tried reinstalling Firefox, restoring all settings to default, disabling all addons, extensions, etc. When I try to load a video, a dark rectangle appears where the video should and my cursor just shakes. In Chrome, Internet Explorer, etc. the videos load and play with no problems, no hesitation, so it must be some setting or some bad file with Firefox, but I feel like I've tried everything.
I'm using Windows 7 on an HP laptop. I've checked my Firefox settings against those on my desktop PC and can find no variances. This problem is driving me mad, so please help.....
Thanks.

You can also disable hardware acceleration in Flash: 
Some problems with Flash video playback can be resolved by disabling hardware acceleration in your Flash Player settings. (See [[Flash Plugin - Keep it up to date and troubleshoot problems|this article]] for more information on using the Flash plugin in Firefox).
To disable hardware acceleration in Flash Player:
#Go to this [http://helpx.adobe.com/flash-player/kb/video-playback-issues.html#main_Solve_video_playback_issues Adobe Flash Player Help page].
#Right-click on the Flash Player logo on that page.
#Click on '''Settings''' in the context menu. The Adobe Flash Player Settings screen will open.
# Click on the icon at the bottom-left of the Adobe Flash Player Settings window to open the Display panel. [[Image:fpSettings1.PNG]] 
# Remove the check mark from '''Enable hardware acceleration'''.
# Click '''Close''' to close the Adobe Flash Player Settings Window.
# Restart Firefox.
This [http://www.macromedia.com/support/documentation/en/flashplayer/help/help01.html Flash Player Help - Display Settings page] has more information on Flash Player hardware acceleration, if you're interested.
