I'm on a mac running OS 10.10.3 and just installed Firefox 47.0.1. However, I am unable to connect to any website but receive

"Your connection is not secure

The owner of www.google.com has configured their website improperly. To protect your information from being stolen, Firefox has not connected to this website.

This site uses HTTP Strict Transport Security (HSTS) to specify that Firefox only connect to it securely. As a result, it is not possible to add an exception for this certificate."

This is the same message I receive for every website, including Mozilla. I have been unable to find a workaround and so far this has made the entire browser useless. It is only effecting Firefox, as Chrome and Safari are working perfectly fine.

When I open a webpage which is in French, how can I get Firefox to askme if I want the webpage translated into English? Firefox used to open a strip at the top of the webpage which allowed me to click yes to translate the page. Firefox 3.6.13 does not do this now. I have found that Translation Add-On's do not do the trick easily. Any ideas please?

My desktop is running Windows 8, which recently crashed. Since then, every time I start up, Firefox 17.1 (which is in the startuo folder) does not load, but brings up an error window saying (Couldn't load XPCOM). Dismissing the window then allows me to start Firefox myself. I have uninstalled Firefox (but not the personal stuff), downloaded a new copy of Firefox 17.1 and re-installed.... same thing happens.

Just to clarify ..... this only happens once, following the initial boot up of the desktop. I dismiss the error window and all is well after that.

Any bright ideas please?

What is XPCOM referring to? A missing dll file? can I find this file elsewhere and move it to the correct location?

Many regards.

I have been using the Downloadhelper add-on for years on my laptop with no problem. I noticed about three days ago it was no longer working with any Youtube videos. The rotating icon is still working, and when I click on it, it still gives me the file type choices for downloading. However, after I click my choice, the green arrow shows the downloading process, but comes up '0 bytes' for every type of video.

I am not having problems downloading videos from other sites that I've used before, just Youtube.

Also, I am able to use Downloadhelper with Youtube on my other computer without a problem.

Can you please help? Thanks.

I'm trying to run an application that displays competitors' routes at an orienteering event. My problem is that Firefox blocks the Java applet. I get a window saying "Application Blocked by Security Settings. Your security settings have blocked an application from running with an insecure or expired jre."

I've tried looking at the Firefox help on "How to enable Java if it's been blocked", but that's no help. It talks about clicking on the red plug-in icon in the address bar, but there isn't a red plug-in icon in the address bar.

The application is from www.epoc.routegadget.co.uk. It worked when I used it last Sunday.

Help, please!

Windows 7, Firefox 30

After changing how Firefox handled cookies (changed to forbidding 3rd party cookies, asking permission to set cookies), I rebooted my system, and Firefox would not start - I got the error message in the question.

Where can I get a full download of Firefox version 54? I don't want the latest version and I'd prefer to get it from Mozilla itself to avoid relying on another party.

Since the last update of Firefox a lot of my addons don't work anymore. Some of these (security) addons are of greater importance to me than any security issues that a new version of Firefox might fix.
