Firefox is suddenly a blank screen for a specific Web site.

A Web site, I used over the years that I have suddenly can't use Firefox, but I can using Internet Explorer. When I try to go at it in Firefox I get a blank white screen in the browser. I tried all the usual troubleshooting techniques (disabling modules, reset Firefox, delete cookies and temporary files) and nothing helped.

I have Webroot antivirus and it does not detect it; scans run automatically each day.


Are there special icons on the address bar that blocks Firefox content?

You can get a Lego icon that is possibly colored on the left end of the address bar Firefox blocks a plugin.

You can check if there is a shield icon to the left of the "Site Identity" (globe/lock) button on the address bar which mixed the active content is blocked.

You can use the following steps in case of problems with web pages:

Reload Web pages and ignore the cache to refresh potentially stale or corrupt.

  • Hold down the SHIFT key and click the Reload button
  • Press 'Ctrl + F5' or 'Ctrl + Shift + R' (Windows, Linux)
  • Press 'Command + shift + R' (Mac)

Clear the cache and cookies only from Web sites that are causing problems.

"Clear the Cache":

  • Firefox/tools > Options > advanced > network > content caching Web: 'clear now '.

'Delete Cookies' sites causing problems:

  • Firefox/tools > Options > privacy > Cookies: "show the Cookies".

Start Firefox in Safe Mode to check if one of the extensions (Firefox/tools > Modules > Extensions) or if hardware acceleration is the cause of the problem (switch to the DEFAULT theme: Firefox/tools > Modules > appearance).

  • Do NOT click on the reset button on the startup window Mode without failure.

  • Cannot type in any text box for a specific Web site


    I have a site and I can't type anything whether in any textbox (search box, for example) when you use FireFox. I tried the site safe without the effect of loading Mode, I can not type anything.

    I've seen similar behavior, but it always seems to get it fixed by disabling modules while in my case is not.

    I checked out the site on Windows, Mac and Linux, in all, it's the same behavior if you are using FireFox. With all other browsers, the site is very good and I can type in these text boxes.

    Let me know if this has happened to someone else, I am trying to settle this problem because it's really annoying for readers.

    Thanks in advance!

    I see the same thing on this web page.

    It seems that some JavaScript on this page is not working properly and therefore does not select the input field or text box when you click it.

    I can achieve input field by pressing the Tab key until I get a slider, so you can use it as a workaround for now.

    You can contact the site and inform them that their site does not work in Firefox.

  • How can I configure a secondary Navigation menu expandable linear stands for the specific Web site pages?

    I'm looking to set up a secondary Navigation menu that is customized to specific pages on my site. I tried to do this using the Widgets Library > Menus > Vertical, then dragged the vertical menu on the page. I know how to add sub-pages using the + box, but I want the subpage names at shOE upward in a specific way. The problem I have is, I want the secondary navigation menu to have a specific look, with "pages" of the menu running in the vertical menu format and subpages if poster in a schema extensible sub-navigation form (see image below), so that when I click on a homepage of the sub navig. menu, all the sub pages expand underwear, slightly indented (so that the hierarchy of the pages is obvious). Then, when I click on a different home page and its subpages below expand, I want the subpages of the homepage previously clicked on to disappear. I've seen websites set up in this way and I like the simplicity, the functionality and look of this type of secondary navigation, I don't know how to do. Does anyone know how this can be done? I am ready to go the "long way" If that's what it takes. Thank you. AdobeMuse-SecondaryNavig.jpg

    You can use the widget panel tabs to achieve this. (formatting to your look)

    Just add some text in each Panel and a link to the specific page.

    The only drawback is you wouldn't be able to link the main headings (Commercial... etc)

  • Why am I now plugin prompts for each unique Web site I visit now with Dragon Dictate active?

    We used the Dragon Dictate pay during the last 4 months without problem (I think the last 2 versions of Firefox). Now given that the new version launched this morning, there are alert pop up for every single website visited - 'Allow to run Dragon Dictate Internet' as well as 'Keep blocking' or the 'Allow' button Why is this here since it was not present before? Surely, there must be a global setting where I can turn it off instead of having to click a button and choose 'Allow' for each unique Web site, that we are going? Or is - something that Dragon has set in the way he treats the new version of Firefox?

  • Is there a solution for Firefox running with a blank screen (no text or graphics) in Ubuntu 12.04?

    After receiving the upgrade to Firefox 40.0.2 a white screen appears. It is not possible to change the settings of Firefox since the opening page because no text or graphics are displayed. This has happened on two computers, an emachines T3624 and a Gateway 2000. I tried a complete elimination and new installation using the Synaptic Package Manager. I am writing from the Chrome browser.

    I tried to create a user.js file in the Firefox profile folder and adding the line:
    user_pref ("gfx.xrender.enabled", false);
    Who has not resolved the blank white screen issue.
    Then I tried to disable the file prefs.js and user.js file by renameing them.
    It worked. When I restarted Firefox, a new prefs.js was generated. The prefs.js file that causes a blank screen has the user_pref ("gfx.xrender.enabled", false); line in it. The new prefs.js didn't user_pref ("gfx.xrender.enabled", false); in it.

    So, I found the prefs.js file in other machine with the same problem and commented of the user_pref ("gfx.xrender.enabled", false); line. (I guess that remove this line would also work.) Firefox now works on the second machine and is no longer launches a blank white screen.
