Firefox Support Forum

After I uninstalled Firefox, all icons returned to usual PDF icons and files were identified as "PDF" files, but when I installed Firefox (31.0) again, all PDF files again are identified as "Firefox HTML document". Extensions do not change, they are always .pdf, and files automatically open in Adobe Acrobat, but icons became "firefox HTML documents" icons and it is very confusing.

i reinstalled firefox to my desktop the previous one used to show my homepage google when i opened a new tab in my home page .but it doesnot open my homepage google now it is blank with some rectangular blocks

Why has the function of my up & down arrow keys changed? Did I click something by accident? Help please?

(My new kitten *might* have stood on something on my keyboard - she's done that before & put Full Screen mode on, but I managed to fix that)

Normally, I scroll down a web page a bit at a time using the down arrow key on my laptop keyboard. Since yesterday, when I press the down arrow, the page jumps to the bottom (like pressing PageDown would do) and the up arrow jumps all the way back up.

How do I set it back so that it scrolls a bit whilst I press the key?

I never save passwords - never have, never will. Using evil IE, Gmail works correctly in that it prompts me for ID and password for each new browser instance. Yet when I open gmail with FF, it goes straight to my inbox without prompting for ID or password. I use gmail in "always secure" mode. Cookies are enabled, of course, just did not expect my password to be saved and loaded from a cookie. How can I rectify this problem?

I was trying to download: https://addons.mozilla.org/en-US/firefox/addon/smallringfx-darkmagenta-213952/

The tab came up top, and said the following: This add-on could not be downloaded because of connection failure

I will soon be getting a new computer. Having a large number of websites and respective access passwords saved in Firefox Mozilla, it would be very convenient to be able to export this information to the new machine after installing Firefox, as one can do with Bookmarks. Is this possible for websites+passwords?

My Firefox is completely unresponsive. I can't get a browser or anything. I just grabbed the application folder and threw it in the trash, because the add/remove program function did nothing. I also cannot download the newest version of Firefox. It tries, but then says, "Your download was interrupted".

How can I make sure I've removed ALL of the old Firefox and what can I do to download the new one?

I know how to set the homepage for the Initial Screen when the Firefox starts but whenever I open a new tab it opens as a blank page. I want to set Homepage for all the new tabs that open (just like we have in Internet Explorer).

== I installed the latest update.

Tried two ways:

(1) Adding through the automated mechanism whereby I am prompted about the untrusted self-signed security certificate of the URL. When I clicked on the "Confirm Security Exception" button nothing happens. I don't see the URL being added to the exception list.

(2) Adding manually through the Option Menu. The URL was truncated into xxx.xxx.x.xxx only. I still cannot access to my firewall.

Previously, the icons for add-ons (e.g., noscript, the weather, or reminders) were displayed at the bottom of my screen, and I could click on them to perform the relevant function. Now they are not displayed, and I don't know how to get them back. I'm particularly interested in getting back noscript, as I almost always use it, but I regularly accessed a lot of add-ons from the now-missing information bar. I don't even know what this information/icon bar/display is called.

Real Player Video Player no longer provides option to download after my Firefox / Adobe Flash Player updated. How can this be fixed?

== After FireFox / Adobe Flashplayer Update

Until today, I had no trouble opening Adobe Acrobat files with Adobe Reader 9.5. (I need to use an old version of Adobe Reader, because I use a program called Macro Express that does not recognize later versions.) Starting this morning, when I click on an Acrobat file, I am asked which program I want to open it with. Even when I click "Do this automatically...", it doesn't do so. It asks me every time. I went into Tools, Applications, and changed all of the pdf related issues to open with Adobe Reader 9.5. This also doesn't work.

Mozilla Firefox updated to version 36.0. When I click on the Firefox icon to open it I receive the message: "Mozilla cannot find runtime" I receive the same message if I try to open Firefox by selecting "firefox.exe" from within the Program Files. I subsequently uninstall Mozilla Firefox and reinstall it. It will open and run normally right after the re-installation. Then if I close the program and try to re-open it again, I get the same "Mozilla cannot find runtime" error message.

The only way I can get Firefox to open is if I uninstall and re-install it every time I want to open it after the initial re-installation.

I have had a problem with Firefox freezing when I try to do just about anything other than simple browsing for at least two years. Updates don't help nor disabling all add-ons, nor reinstalling, etc. Nobody can figure out how to fix it so I use it as-is. I would like to update the Adobe Flash Player add-on but Firefox freezes every time I try. Is there a way to update the Flash Player in Firefox with actually running Firefox?

Thanks

Running XP SP3 and latest Firefox. Also running IE8 using the latest Flash Player.

I'm trying to log into a hotmail.co.uk account via mail.live.com and keep getting the above error. I have cleared recent history and disabled Adblock but no success. I'm using Windows 7 SP1 and Firefox 5.0:

The page isn't redirecting properly

 Firefox has detected that the server is redirecting the request for this address in a way that will never complete.
       
 This problem can sometimes be caused by disabling or refusing to accept
   cookies.

The error page then received is as follows:

Server Error in '/' Application. Runtime Error Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine.

Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off".

<configuration>

   <system.web>
       <customErrors mode="Off"/>
   </system.web>

</configuration>

Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's <customErrors> configuration tag to point to a custom error page URL.

<configuration>

   <system.web>
       <customErrors mode="RemoteOnly" defaultRedirect="mycustompage.htm"/>
   </system.web>

</configuration>

Would appreciate any help you can give. Many thanks, Ben

FF has blocked Flashplayer and Java. I have updated both to latest versions BUT Java Deployment Toolkit 8.0.510.16 11.51.2.16 is still blocked and cannot be activated (or apparently updated). The option "ask to activate" is selected but does not do anything. "You cannot UNINSTALL this program because: Why I am not able to run the Java Uninstall tool and the Java verification applet? The Java Uninstall Tool and the Java verification applet uses the Java DT to do Java version detection on the user system. If Java DT is blocked by browser (like Firefox) than these applets will not run. In order to run these applets the user will have to permit Java DT to run in browsers." https://www.java.com/en/download/faq/deployment_toolkit.xml

So, there is a Catch 22. It needs to run itself to uninstall but it can't. How can this be resolved?

As an additional comment - flash and Java run in MS IE - which is considered less secure. Mozilla are forcing people to use an inferior product. Best Regards, Chris
