Shockwave Flash 12.0.0.77 keeps crashing. It was only installed on 14 March 2014 and I am told it is up to date. I am running Firefox 28.0 on Windows 7 home premium.

The message I get is Warning: Unresponsive Plugin Shockwave Flash maybe busy, or it may have stopped responding, <snip>

I used to get this with an older version of Shockwave Flash and an older verison of Firefox, but in the last few days it has started to happen again (since I updated Firefox to the latest version).

When I watch a video with Mozilla Firefox on sites like YouTube, Google Video or Bing Video in full screen the taskbar shows at the bottom of my screen and doesn't disappear like it does in Internet Explorer. How do I watch videos in full screen without the taskbar showing? It's not a website problem, it's not a Windows problem, it only does this on Mozilla Firefox's browser. All three websites play perfect full screen video on the Internet Explorer browser with no taskbar showing at the bottom..

Hello everyone, sorry for the long post.

For the last 3 days, I have been experiencing a very frustrating issue with videos posted ONLY on Facebook.

Every time I try to open a Facebook video, the Facebook player opens (the one where you can see comments and likes on the right side), and Firefox gives the impression that the video is loading. But after a while, a 'cross' appears in the middle of the screen, below which 'No video with supported format and MIME type found' is written [Kindly refer to the attached screenshot].

Prior to this problem, I had NEVER, in 2 years, experienced any issue whatsoever with playing ANY videos on the Web. Firefox just suddenly decided to stop playing Facebook videos.

WHAT I ALREADY TRIED: - Reload video pages and play them again (FAILED) - Clear cache, cookies and restart Firefox (FAILED) - Start Firefox in Safe Mode (FAILED) - Uninstall Flash Player, try to play videos with the default Firefox player (any video on the Web would play, but Facebook videos FAILED) - Enable the Open H264 Cisco codec (FAILED) - Changing a few values in about:config *(such as media.directshow.enabled) to true/false (FAILED) - Refresh Firefox from https://support.mozilla.org/en-US/kb/refresh-firefox-reset-add-ons-and-settings (FAILED)

ADDITIONAL INFORMATION: - I use Firefox 35.0.1 and have no other browser (besides the default Internet Explorer 6 which I never use) - I use Windows XP SP3 Professional - I have not downloaded/installed any software/extension/add-on which could have caused this problem

I still love Firefox, and have no intention of migrating to a competitor's browser, which is why I hope a prompt solution shall be found. As well, I am not considering dropping XP SP3 anytime soon; it is very stable and fulfills my requirements.

Thanking you for your time.

My Pc had a virus, and trend helped me remove it, but now every time I sign on to Fire Fox the fallowing notification appears The proxy server is refusing connections Firefox is configured to use a proxy server that is refusing connections. Check the proxy settings to make sure that they are correct.

Contact your network administrator to make sure the proxy server is working.

I want to disable javascript for websites. I've done this in the previous versions of firefox by unchecking box in options/contens. But there is no disable javascript option in firefox version 29.

I have a windows 7 system that I do not have tied to the internet and I would like to install firefox onto it because some applications that I am starting to use wants to have a browser on it. The systems do not 'like' windows IE and like either Chrome or Firefox. So I would like to get the whole package of Firefox installed, not a loader that is a loader.

Thanks Frank

firefox 24.0 in xp. I continually (about 30 times an hour) get "pop-ups" that has a tab at the top that says "Firefox stopped redirect" or something like that. I still have to waste a click to close the window. How can I get firefox to stop the window from opening. what are other types of pop ups that can be blocked? I have read some on this about some ads cant be blocked.

An error occurred during a connection to 192.168.1.24:2400. SSL received a weak ephemeral Diffie-Hellman key in Server Key Exchange handshake message. (Error code: ssl_error_weak_server_ephemeral_dh_key)

Am getting this error .. how do i solve ?

I do not like the search engine Bing - it posts nasty images automatically when I pull up my Mozilla Firefox. How can I remove it completely from showing up with Mozilla and if possible how do I make Google automatically be the search engine that accompanies Mozilla?

UPDATE! This question is not marked as answered, as the issue is a new 'feature' of Firefox 22, and if you read all the comments you'd see that. Clearly, with the large volume of 'new' answers coming in saying the same thing over and over, people aren't, so I'll say it here: THERE IS NO NEED TO ANSWER THIS QUESTION ANY MORE.

I recently asked about my UI being big and fuzzy, and managed to get that fixed in the about:config, but websites are still big.

For some reason, the default zoom (ctrl+0) is at 120%.

I tried the FullZoom and NoSquint addons, but both had one issue. They messed up the top level image view (which for me works with the old default image style addon) and made the unzoomed image a bit bigger than my screen, and the magnifying glass icon which should appear with a + or - in it when I mouse over the image is just a regular mouse pointer instead.

How can I reset the default zoom to be 100% (or preferably about 80% because even 100 seems to be overcompensating for my high dpi screen) without an addon messing up my default image view?

Further details. If I disable the 'old default image style' addon, the top level image view works fine with the NoSquint or FullZoom addons.

Just recently (I believe on Oct 30) I have been encountering this problem while trying to log into the Rooster Teeth web site. I have tried clearing cookies and cache multiple times to no effect, and the help page suggestion for the workaround of clicking "Or you can add an exception..." doesn't work because that button does not appear on the warning page anymore. I am only getting this warning error when trying to log into ( http://roosterteeth.com/home.php ) and only while trying to log in, it doesn't pop up for anything else on the site or any other site that I've gone to. Any help on fixing this problem would be greatly appreciated.

I am unable to access my GlobeInvestor Streaming Quotes (http://finserv.globeinvestor.com/fcclient8/mainframe.htm) via GlobeInvestorGold.com. When I click on the "Tracker" link on the GlobeInvestor Gold website to access my streaming quotes, I get a pop up with an error stating:

Name: fccapp Location: http://finserv.globeinvestor.com Your security settings have blocked an untrusted application from running.

I have restarted Firefox numerous times. I have reset Firefox. I have re-installed Java a few times and I have also updated all plugins. I am running Firefox on my MacBook Pro. If you could provide any assistance, I would greatly appreciate it. Thank you so much in advance.

I don't know why I don't have the correct ssl certificate or whatever. I use firefox 60(nightly) I am not sure if I deleted my certificates or what may have happened but it says ssl_error_weak_server_ephemeral_dh_key I don't know exactly what this means or how to get my dh key to give them the right key.

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.
