• Firefox won't open the shockwave flash files because there are 2 types?

  Firefox does not open some swf files when I say that this is the cause. However, http://edmullen.net/test/poopboy.swf works fine.

  I looked in my Options-> Applications menu and found this http://i.imgur.com/kPVOHdE.png

  So it has got 2 different types of SWFs to meet him. I can't tell the top affliate background is the same way.

  I tried to uninstall the plugin. This removed the bottom and meant that the poopboy.swf I also linked didn't work in the same way, however, put it back, I was just back to the drawing board.

  I want to add that these particular .swf files that I'm running worked yesterday so file corruption is not the problem, especially since I went and all the redownloaded.

  These two SWF entries are on different MIME types that first one appears to be damaged or at least unusual. and probably the second (application/x-shockwave-flash) should be there.

  You can rename (or delete) the file mimeTypes.rdf in the profile folder of Firefox to reset all the actions file.

• Firefox won't open any search with a search engine query. All are UNTRUSTED.

  I run the operating system MS Windows 7 Premium with Kaspersky as my security software.

  Then checked again. It seems to be security settings of Firefox and not Kaspersky causing the problem. Just in case it's Kaspersky, I added Google as an exception, but the problem persists. I also added Google as an exception of certificate in the Firefox config. and the problem still persists.

  The problem:

  I just can't open any page of web search in Firefox through any search engine because Firefox says that all are "unreliable", but I can open these pages in other web browsers.

  Any search gives this:

  Well the miserable loader does not load the image. So much for this, but basically, the notification is that "THIS CONNECTION IS UNTRUSTED" and the issuer of the certificate is unknown. Says error code "unknown sender".

  I do not get the ability to ignore the warning, so I have no other choice but to close the page each time. A nightmare, what makes Firefox unusable. Not sure that this is being caused by a recent Google update or the update of Firefox.

  I've checked then once again my security settings of Firefox and for the life of me, cannot understand why this has suddenly started happening out of the blue.

  Please note:

  1. I have Google as my search engine by default and Firefox as my home page.

  2. I've updated automatically, but had to remove like my Firefox default browser - temporary I hope.

  3. I've never used the default theme of Firefox.

  4. I already re-set/updated the browser by using the refresh/reset link in everything: support/troubleshooting Information. That did not help.

  5. I have Google as a reliable (in exceptional cases) site, in Firefox and Kaspersky, but that doesn't seem to help.

  5. have you spent to help and clicked on everything: firefox and get this report:

  Well there it is again - uploader is still running madly and never deliver - 10 minutes later - nothing downloaded. Version control on my Firefox in a dialog box States: 'FIREFOX 40.0.2 Firefox's update

  6. again on another page the search for my problem, I see this:

  Far out! Why this uploader freaking does not work? I have to type everything, besides being tedious, this gives you no verification. A line of text after another says:

  "Congratulations!" You use the latest version of Firefox.
  "Looks like you are using an older version of Firefox. Update on the Google game'
  "Contgrats!" You use the latest version of Firefox.

  Then further:

  In an area of button: "Refresh Firefox" I made according to the description.

  Immediately below that, it says:

  'Looks like you are using an older version of Firefox'... and in a direct link below:

  "updated to stay fast and safe"... Is this for real? [This would be more credible in a screenshot].

  7 about: support/troubleshooting Information I deleted my profile page and restarted Firefox by following the instructions.

  8. made no difference. Delete the file again and everything closed and restarted the system. That didn't work, either.

  9. all the text that I read in Firefox 'aid' resembles a cached page. I can't reveal all 'real' web pages in Firefox browser in Firefox support at all for some reason any.

  I love Firefox as a browser, but hate its constant glitches. For more than 10 years, I hate to admit it, I used that is never a problem. Then I switched to Google Chrome for another 5 years, with never a problem - outside the mining data and espionage which I hate and that's why I finally changed to Firefox. Firefox is the choice... but it's also a bloody choice as head banging and maybe it's just enough to make me give up on this.

  https connections are there to make sure you're traffic is encrypted and you talk to the Web server that you expect to. What happens technically with kaspersky, it is essentially a man-in-the-middle attack, which firefox reports to you as it should be - your web traffic does not go to google when you type in www.google.com, but for kaspersky.
  There are ways around that for av-vendors (such as the injection of their certificate root in the browser (it might go missing again after an update of firefox), but if there is a problem with you contact kaspersky support because they will be responsible for applying the product they offer properly.)

  in all cases, allowing the characteristics as https in your av software can even let you more vulnerable, because browser vendors have now greater expertise in how to use and implement encryption properly: http://www.scmagazineuk.com/updated-kaspersky-leaves-users-open-to-freak-attack/article/411470/

  Firefox is compatible with system Suite 12 anti-virus?

  Try the Firefox Safe Mode to see how it works there. Safe mode is a troubleshooting mode, which disables most of the modules.
  

  (If you use it, switch to the default theme).

  • You can open the Mode without failure of Firefox 4.0 + holding the key SHIFT key when you use the desktop Firefox or shortcut in the start menu.
  • Or use the menu option help and click on the restart with the disabled... modules menu item while Firefox is running.

  Do not choose anything at the moment, just use "continue mode without failure."
  To exit safe mode of Firefox, simply close Firefox and wait a few seconds before using the shortcut of Firefox (without the Shift key) to open it again.
  If it's good in Firefox Safe Mode, your problem is probably caused by an extension, and you need to understand that one.

  To do this, please follow article Troubleshooting extensions, themes and problems of hardware acceleration to resolve common Firefox problems .

  When find you what is causing your problems, please let us know. It might help others who have the same problem.

• Firefox won't open, not even in safe mode!

  Everything worked Friday (when I finally used Firefox) but this morning when I turned on my computer, Firefox will not work. I tried clicking on the toolbar button and the link in the start menu, nor work. I tried uninstalling and reinstalling, does not help. It gives me a little icon running, but disappears quickly without having to open Firefox at all. Is someone can you please help me understand why I can't get Firefox to open? Internet Explorer works fine, so all I can imagine is that an update has occurred during shutdown Friday.
