This should be a simple process, as I have done it before on other computers - but the icon is only in my dock as a "?", which I click on , and then it opens up to the Fox/World icon. As soon as I shut down the computer - the Firefox icon disappears.

I'm a web developer that setup a local environment under Linux Mint.

For some reason, Firefox Developer Edition (59.0b7 64-bit) cannot access sites on my localhost. The interesting thing is that Firefox Quantum 58.0.1 (64-bit) is showing these local sites perfectly fine. I've tested other browsers, including Konqueror and Lynx, and these work fine also.

I've setup my environment so that apache2 can serve pages from a 'wildcard' virtual host. Using symlinks, I can link my project files to another directory that functions as the web root. Thus:

/home/me/business/projects/client/index.html => /home/me/business/www/client/index.html

Navigating to http://client.dev brings up the page perfectly in Firefox 58, Konqueror, and Lynx.

However, Firefox Developer Edition, AND Google Chrome, both fail to load the page. The URL changes from http://client.dev to https://client.dev and throws this message:

"Unable to connect

Firefox can’t establish a connection to the server at client.dev."

I've played around with the about:config settings for Network.dns.* but nothing seems to help. Also, the apache logs do not produce anything useful.

Your input will be greatly appreciated.

I am getting a solid red screen with screeching sound saying a web site is trying to do something to my computer and that it's a FIREFOX CRITICAL ERROR and I need to call help desk. The only way I have found to close the window is to open Task Manager and close Firefox. Sometimes after rebooting the page will go away for a period of time but it always comes back. HELP! How do I get rid of this monster? The Windows 10 Virus scanner won't clear it and neither will Malwarebytes malware scanner.

Thank you, Jake

When I first got on the Firefox browser a full page red screen came up with white letters, telling me I should call a certain number (I didn't write it down - didn't call either). On the main red page it said my passwords may be compromised and I should alert my bank accounts, etc., Other smaller alert boxes came up, but I don't remember what was in them. I eventually cancelled all those alert boxes and logged of. The next time I got on Firefox was fine. Does Firefox give out numbers to call in a case like this? Is my computer infected? Thank you/

I am trying to display streaming content from 4 webcams within my local network. This works properly on my Linux Mint box with Firefox 48.0, but does not work on My macbook running OSX El Capitan 10.11.5 on Firefox 50.1.0. Also same problem on my IMac.

The html code is like this...

<object type="application/x-vlc-plugin" data="rtsp://LWK-????:????????@192.168.1.xx:554/img/video.sav" width="500" height="375" id="video1"> <param name="movie" value="rtsp://192.168.1.0/archive/xxxxxxxxxxx"/> <embed type="application/x-vlc-plugin" name="video1" autoplay="no" loop="no" width="500" height="375" target="rtsp://LWK-????:????????@192.168.1.???:554/img/video.sav" />

I downloaded Flip4mac, as was advised on a post I found on stackoveflow, but that made no difference.

How do I know which plugin is needed? Searching on extensions, I see nothing for x-vlc-plugin. Is extension same as plugin? What do I download if not Flip4mac?

Any help would be greatly appreciated, Thanks, Joe

Programming in PHP. kind of a form (actually it is not a form but it uses form elements - js is used to submit.) When submitting, data is stored in session variable, and the page is reloaded, same form is shown, with data modified (formattet different). This shows data the way the user typed them - not the way PHP formats them.

Useless.

And yes, I have verified, with a different display section, that PHP is actually doing what it's supposed to - but firefox does not display data in input lines, the way they are programmed - they do not display the programmed value, but the value the user typed last time.

Likewise the web tool, does not show the actual sourcecode, but a modified version of it. Selecting "View Source" does not give the same source as "Inspect element"....

There is right now literally no obvious way to bookmark a page. This is a serious flaw in the browser.

The Forum instructions say to restore it from "Customize." But it's not there, just the bookmark menu button, which does not allow you to bookmark a page. It then says restore defaults. That doesn't restore the star either. Does anyone know how to get it back once it's gone? It should not be so difficult that I can't figure it out.

The Firefox plugin checker is reporting "Update Now" for VLC media player Web Plugin 2.1.0. The 'update now' link invites me to download Plugin 2.1.2. but i already have 2.1.2 installed so the plugin checker is detecting the wrong version. I have had v2.1.2 installed since December 9th 2013 and run the plugin checker on a weekly basis so i'm not sure why it has suddenly decided that this is a vulnerable plugin.

I am running Firefox 26.0 on Windows XP

Hi,

I have a spr532 card reader with a test smartcard with Firefox 50.1.0 on Ubuntu 16.04 up to date. I want to use the client certificate from the device to log in on a website that I am developing.

I also have a test certificate that I generated and it is not on the card. I can log in with the test certificate that I have but not with the one on the card. The problem is that in the "User identification request" page I cannot see the certificate from the smartcard. I can see my generated certificate but not the one on the smartcard. Firefox asks me for the pins for the smartcard (I have two certs on the card and they both have PINs). Firefox sees my certs from the smartcard in about:preferences#advanced > View Certificates > Your Certificates column. I have both the certs on the smartcard and the one I generated in that table. But when I try to log in, Firefox only shows me my generated cert and not the one from the smartcard.

What can I do? How can I debug this? This is a dev environment. I can change any configs on the server so I can decrypt the TLS session and see what is going on between my server and the browser.

PS: I tried to send this message with 2 other email accounts but I do not get the confirmation email.

Thank you!

I have to use Windows 10 (Home v:1703).

I'd like Firefox to be my default browser, but it's not listed in 'Choose an App'.

There's just Microsoft Edge listed, along with Internet Explorer, and an option to choose an app from the shop.

Microsoft Edge is also presumptuously shown as the default app to start with.


If Firefox isn't listed, how can I set it to be my default browser - or, isn't this 'allowed' in Windows 10 ?

Hi!

After update to 56.0, I was getting multiple following messages when starting and/or using Firefox. Eventually, all my bookmarks loaded without problem, but the error windows appeared consistently:


"Your Firefox profile cannot be loaded. It may be missing or inaccessible."


Attempted solutions (with no success):

 - Delete %appdata%/Mozilla/Firefox/profiles.ini file
 - Delete the whole %appdata%/Mozilla/Firefox folder
 - Re-install firefox
 - Delete the %appdata%/Mozilla folder, delete C:\ProgramFiles\Mozilla Firefox folder and re-install
 - Remove old profile and add new one using "firefox.exe -P"
 - Repeat some of the above 5x

Working solution: Reboot

 - I noticed Kaspersky antivirus was demanding restart after its own update.
 - Firefox error said "inacsessible", and antivirus frequently locks out our files during development.
 - Kaspersky forces its plugins into browsers, so I gave restarting it a try.
 - The Firefox works after reboot with no errors even with the original (restored) contents of the %appdata%/Mozilla folder.

Suspected cause of the problem:

 - The Kaspersky automatically installs its extension into browsers (even after manually removing or disabling them). 
 - I suspect that the updates/installs somehow conflicted.

EDIT: Reformatting for better readability. Added missing info into "attempted" solutions.
