I need FF on Linux basis for kiosk with tuchscreen. So it should start automatically from command line (console) in fullscreen mode without window, menu, tabs, adress line and side ruler. I guess I may configure it in some conf file and use some options in command line, but where can I find the full list of options and conf file description?

How to know if the page someone is browsing is HTML5?

For example, if I'm browsing php webpage then I right click on the page and "View Page Info", I get this: Type: "application/xhtml+xml".

I tried that on HTML5 webpage but I got the following: Type: "text/html".

The printer was working fine. Suddenly that changed. Now when I print, the print is huge and a large part of the text is cut off. I tried reducing the size of the font but that did not help. This had happened to me before about a year ago and I tried different things with firefox and was finally able to fix it. However, this time I have tried all your troubleshooting tips and nothing works. The print function was working normally up to a couple of days ago and to the best of our knowledge neither my husband and I have made any changes to the settings.

In Firefox 21 for Mac OS, there is no longer any preview image, which is usually a little screenshot of the left end of the toolbar, shown for a theme when you click the "More" link to get more information about the theme. The only image there now is the theme icon. Where did that preview go and why is it gone? The preview images are still in the .jar files in all the themes I have, so they are still available.

I have the Android device that support external usb hard drive, when I want to download some files via Firefox there are only two possible "places" where I can put the files - external memory or SD card. It will be nice if there would be an option to save file on ext. usb drive.

I would like to change the background colour of the 'about' pages to #EFEFEF or a named colour if such code cannot be used and, if possible, the font colour as well. The white background is my main focus.

I am hopeful that the colour(s) can be changed using the userChrome.css file.

I have been unable to find an answer to the specific question or any source providing a comprehensive list of element and attribute names.

I am using Firefox 20.0.1 on a Linux operating system.

Hi, I'm using the latest Firefox for Android browser on a Samsung Galaxy S2 Epic 4G Touch. I have an issue when I download an image from a website onto my phone. After I download the image onto my phone by holding my finger on the image and selecting save image, it downloads it into my gallery, but I'm unable to share the image in a text or to Facebook or anything. It just comes up with a prompt that says "no applications to share image". I've never had this issue after downloading images using the phone's native browser, but I prefer the Firefox app to that. Is there a way to fix this, is it a bug, or is it supposed to do that? Thank you.

I am trying to find out if my computer uses SSE2 and how can I find this out. I am not sure of all the information you need to answer my question, if you need more please let me know and what it is. Thank you

How do open one instance of FF and have 2 tabs open visible side by side. Or is this not possible and I have to have two instances of FF open and size the screens to half the monitor?

I have two websites for personal use (as an online portfolio), however when I come to 'copy' and 'paste' any information across (as the sites share a common theme) it adds in a lot of question marks all over the stretch of text. This is incredibly annoying as they don't show up when initially pasting across, but only when posting so I've been having to post twice to get it to look correct. This issue has been happening on every PC I've tried to access my site on (and they all only have firefox) - will I need to change up my browser or is there something I'm missing?
