Exactly. It's not a very good solution to be forced to give up control/accessibility on every Web site, to fix a problem with just a few popular ones like Twitter.
It seems like a pathetic accessibility fail on the part of Yahoo, Twitter, etc., but since the practice is likely to persist and spread, please, Firefox:
=> allow site-specific configuration of "allow pages to choose their fonts."

Firefox will not display basic content on certain (common) sites

Hi there:
On certain websites (common) ones Firefox will not display options on the website.
These sites include Yahoo Mail, Twitter, Weebly.
An example would be if there is a menu of choices such as delete, ad, tweet, etc. instead of displaying correctly it looks like a box with 4 dots.
The other browsers are fine. I have the latest Firefox and this started with the previous version as well. I uninstalled/reinstalled without change.
Windows 7 Computer/Norton Anti Virus.
If allowed I can upload a screen shot.
Thank you.

Firefox will not display on the screen even though with Process Explorer I see Firefox.exe active but no CPU usage

I use Firefox v10.0.2 as default browser on Dell XPS8300 e/w Intel Core i5 & Windows 7 Ultimate and Compaq Presario CQ57 e/w Intel Core i3 & Windows 7 Home. More frequently on the (about 90% of attempts) than the Dell (50% of attempts) Firefox will not display to the screen when I click on icon. When it happens I cannot display other programs. I specifically say display because I believe Firefox has started. To circumvent the problem I installed Process Explorer on both machines and start this program first then click on Firefox icon. When problem occurs I can see Firefox.exe process in Process list; some CPU consumed but, then, no CPU activity. If I click on Firefox icon again another process opens in Process list but with same response - some CPU consumed and then no CPU activity. If I have 2 processes running and kill the 1st process, the 2nd will display and everything from then on is normal. If I do not open a 2nd process but kill the 1st process then click on Firefox icon Firefox is displayed and everything from then on is normal. This problem has occurred since original installation on both new machines. I've updated video drivers in both machines.

Ok, let's see if we can fix this and get it working for you!
First, if you start Firefox in [[safe mode|safe mode]] (restart your computer first, then when you open Firefox, hold down the shift key) does it start up more reliably? This is usually caused by a faulty add-on. If it does help, then restart Firefox, go into the Firefox button, then add-ons, and disable your extensions one by one until you find the trouble maker.
Also, try updating to Firefox 11, it has several bug fixes that might make life easier here.
Just as a few basic troubleshooting steps to make sure we have all the bases covered,
Run all Windows Updates, install all needed service packs, etc.
Update all your plugins (Flash, Java, etc.): [http://www.mozilla.org/plugincheck/ http://www.mozilla.org/plugincheck/].
Download and Install MalwareBytes Anti-Malware, run a full Scan. [http://www.malwarebytes.org/ http://www.malwarebytes.org/]. This helps check that there are no viruses on your computer causing issues. you can uninstall this program after you clean off any infections.

Updated to the latest revision. Firefox will not display my chosen home page without clicking on home icon.

Since latest update...Firefox will not allow a new page to be opened from a link in a current page. It will allow a new tab to be opened (with tabbed browsing checked) but i prefer a new page. Even in tabbed browsing links to things like a pdf will not work at all.
Firefox WILL NOT close. X-ing out will close the window but I can not get back to Firefox without closing it in task manager.
Firefox will not display my chosen home page without clicking on home icon.

Start Firefox in [[Safe Mode]] to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance/Themes).
*Don't make any changes on the Safe mode start window.

Firefox will not display videos since Yosemite migration

Good day!
I run an early 2011 15" MacBook Pro, 2,2 GHz Intel Core i7 with 4g 1333 MHz DDR3 Memory, and an Intel HD Graphics 3000 with 384 Mo. Firefox is 34.0.5.
Since I migrated to Yosemite (10.10.1), the browser I use (Firefox) will not display the videos, but plays the sound out of them...
I tried to clear the PRAM (NVRAM) with the Command (⌘), Option, P, and R, but it doesn't work. I even tried to shut down the graphic acceleration option in Firefox, to no avail...
What else should I do? Any solution out there?
Thanks, and Merry Christmas to you all!
Martin

Firefox will not display Yahoo Calendar.

Firefox will not display Yahoo Calendar (I have tried on four separate computers).
When I use Internet Explorer, the Yahoo Calendar does display fine.
Do you know why Yahoo Calendar will not display in Firefox? Is there any solution?

Are you using Firefox 3.5? I am not sure whether Yahoo Toolbar still supports it.. Have you considered upgrading to Firefox 3.6.x or Firefox 5.0? :)

Firefox will not display certain features of websites in windows 8.1

I've upgraded to windows 8.1. Installed Firefox (now ver. 26) right away. I go to the same websites to pay bills, do work stuff etc for the past few years.
Those websites work fine most of the time. RANDOMLY (at least to me) 2 websites have been giving me trouble for certain features:
1. Banking website will not display my online bill pay. It does not crash, it just says "unable to display page" and for me to check my firewall etc, reload page, etc. When I go to other features for my bank, it works fine except for the bill pay.
2. My work website has a feature to display paychecks etc. It give me the same message of "unable to display".
Here's the weird thing: I open and close firefox a few times and the page "magically" works.
I load the same page in IE 11 and I have the same problem.
I load the same page in chrome 32.0.1700.107m and I never have this problem.
I load the same pages in firefox ver. 26 on a windows 7 machine and it work just fine.
I'm at a loss since Firefox is my primary browser and only have the other browsers for the occasional incompatibilities.
Any ideas? I've concluded that it's a windows 8.1 issue/compatibility but would like to try other solutions before I downgrade back to windows 7.
FYI: I've turned off windows firewall and the same issue still occurs. I've updated to the latest adobe flash, shockwave, and Java. I only have one extension installed - adblocker (which is disabled for these websites).
Thanks in advance for any help.

Current Firefox versions have enabled a built-in PDF Viewer that doesn't have all features that other PDF readers like the Adobe Reader have or may not function properly otherwise.
You can change the action for Portable Document Format (PDF) from Preview in Firefox to use another application like the Adobe Reader or set to Always Ask in "Firefox > Options/Preferences > Applications".
You can set the pdfjs.disabled pref to true on the about:config page to disable the build-in PDF viewer.
You can check the value of the plugin.disable_full_page_plugin_for_types pref on the about:config page and remove the application/pdf part if present or reset the pref to the default via the right-click context menu if you want to display PDF documents in Firefox with another application (i.e. not the built-in PDF Viewer).

Firefox will not display characters that were added by the webmaster on user PC?

I employed a company to design a site for me which is great. Then I asked them to add a small button/image in the back end (admin area) that when clicked on will send an email. No image will display so I got them to change it to Text format, still it is not showing on my end. The design company are able to send me emails showing where it is but I cannot see it. It is worthwhile mentioning that it will not display in either IE8 or Opera, Is it a firewall problem ? Or a setting on Windows 7?

Firefox will not display my photo website properly nor play the music from it on my new computer. I have 2 other PCs and it works fine on those.

Just set up a new PC and downloaded Firefox. It will not display my Zenfolio Photo website correctly nor will it play the music that accompanies the main page slideshow. I have 2 other PCs and it works fine on them. All are Windows 7 Home Premium.

Note that there is nothing wrong with setting Flash to "Ask to Activate" and click the Lego block icon on the Navigation Toolbar to activate the Flash plugin when needed.
You can verify on the Adobe Flash Players Test Page that the Flash plugin is working and which version you have once you have installed the plugin and checked the setting in "Firefox/Tools > Add-ons > Plugins"

Firefox will not display my HTML file as its contents - only displays the HTML text (firefox 5.0).

I can download a file as a Firefox file (zipped) and it displays successfully. Then I can save the file as a text file and see the HTML text.
When I work on the HTML text file and then try to display the modified file in Firefox 5.0 and Windows XP, Firefox will only show the HTML text, not the display of the contents of the file.

Make sure that the file has a .html file extension if you want Firefox to render the content.

Firefox will not display login page for Facebook or Mozilla homepage

My wife and I have used firefox for quite come time, we have the same settings on our computers, hers works fine, but my firefox will show the facebook login page and the Mozilla home page only in text. This started about 3 weeks ago, and the it completely crashed on the 24th. I have done clean reinstalls 3 times and get the same results. Anybody else have this problem and come up with a solution? Any help would be appreciated.

Both this support site and Facebook usually use a secure connection. In your Kaspersky software, can you check for settings relating to SSL filtering or HTTPS filtering, or similar setting that enables Kaspersky to scan/intercept secure connections, and make sure they are turned off? Here are some links I found about this on Friday: https://support.mozilla.org/en-US/questions/981541#answer-516280

Firefox will not display (It will not "open", although it looks like it's open in the taskbar)

I'm not sure if it's coincidence that it updated itself to 37.0, but it must be...
When I click on Firefox both on Taskbar and on Desktop icon, it opens on the task bar, when I highlight the task bar it even shows that Firefox loaded Google (my default webpage)... But it never come up on screen.
I have:
- Windows 8.0 (not 8.1 and I do not intend on upgrading since it functions better than 8.1)
- Noscript add-on/plugin, possibly more
- up-to-date drivers
I have tried:
- Uninstalling and reinstalling newest version (37.0)
- Uninstalling 37.0 and Installing from Firefox website archive 36.0
- Restarted my computer after installs
- disabling maintenance service on install
I have "allow"-ed the install windows popup both times and it doesn't help.
The first time it tries to open it does go to the yellow background on taskbar of opened programs you haven't used yet...
However, when I click on it nothing comes on screen. When I highlight it still shows my homepage there. I cannot do the firefox refresh thing because I can't get it to even display. I do NOT get any error messages on my computer, which is more bizarre. I've updated and ran windows defender complete scan and found nothing (but that's not surprising for "defender", lol).
Once it opens the first time, even opening another page opens nothing. Then it freezes and won't close, even if you right click and try to close all windows... I have to use Task Manager to close it by End task...
I don't know how to open the troubleshooter "xpi" thing, sorry....
And not to whine, but why is it so broken all of a sudden XD... And more importantly, how in the world can I get it back working??? I'm using this terrible chrome I was lucky enough to just have on my computer already, which I only had for viewing one single thing a long time ago and forgot I even had Chrome... And as much as I hate using chrome, it's actually working flawlessly for me right now... So please any help will be much appreciated...

Sometimes the Firefox window gets "off screen" somehow. You often can force it to appear on the screen by right-clicking the little thumbnail image above the Taskbar and choosing Maximize. Does that work?
One possible cause for this is that the file which stores window sizes and positions has become corrupted.
'''Method #1:''' ''If you can get a maximized window:''
Open your current Firefox settings (AKA Firefox profile) folder using either
* "3-bar" menu button > "?" button > Troubleshooting Information
* (menu bar) Help > Troubleshooting Information
* type or paste about:support in the address bar and press Enter
In the first table on the page, click the "Show Folder" button. This should launch a new window listing various files and folders in Windows Explorer.
Leaving that window open, switch back to Firefox and Exit, either:
* "3-bar" menu button > "power" button
* (menu bar) File > Exit
Pause while Firefox finishes its cleanup, then rename '''xulstore.json''' to something like xulstore.old. If you see a file named localstore.rdf, rename that one to localstore.old as well.
Start Firefox back up again. Do windows display normally again?
'''Method #2:''' ''If you cannot get a Firefox window at all:''
Shut down Firefox by right-clicking the taskbar icon > Close All Windows.
Using the Run dialog (windows key + R) or the Start menu search bar (or in Windows 8 maybe the charms bar search bar?) type or paste the following and press Enter to drill down to the Profiles folder:
%APPDATA%\Mozilla\Firefox\Profiles
Here you may see one folder -- in which case, double-click into that -- or more than one folder -- in which case, double-click into what looks like the most recently updated.
Scroll down and rename '''xulstore.json''' to something like xulstore.old. If you see a file named localstore.rdf, rename that one to localstore.old as well.
Start Firefox back up again. Do windows display normally again?

I am using Firefox 4 and Firefox will not load Twitter or igoogle.

I have reinstalled Firefox, so I have the latest version. All I get is a blank page for twitter, and my gmail will come up with igoogle but none of my homepage content. This started yesterday. Both pages are working fine on Chrome.

The problem may not be directly related to the Firefox 4 upgrade.
To downgrade see
* [[installing a previous version of firefox]]
* also see [[firefox consumes a lot of CPU resources]]
Presumably you have for some reason already uninstalled any previous version of Firefox so see now [[installing firefox on windows]]

Why will Firefox will not display content when it has loaded the Face Book page?

Firefox (FF) loads the Facebook page but only displays the menu of Facebook. Clicking on menu items does produce results but not the main Facebook page.
