I-Firefox Isithangami Sokwesekwa

Is there an easy way to downgrade from Firefox 49.0.1 to 44? Or, do I need to remove Firefox and download again? I've been reading that the issues I'm having with the Selenium firefox webdriver work better with the version 44.

So I'm getting a error "Your browser does not currently recognize any of the video formats available" and when clicking the link, it says H.264 and MSE & H.264 are not supported. I used to get the black error screen for a split second before the video would blink and (I'm guessing) select another player and just play normally. Today is the first day that I've had this screen permanently displayed and it only shows up for a few videos. I can watch other videos on the same channel, just one or two that have the error.

It's the same if I try it in Safe Mode or with a new profile. I updated Firefox to 49.0, updated java, updated windows media component, and tried it with "media.windows-media-foundation.enabled" true and on false. No changes

I'm at my wits end with this one! I can watch the videos just fine in Chrome, but would much rather prefer to continue to use firefox as my default browser. Any help is appreciated. Thanks!

Win 10 pro, version 1607, os build 14393.321 Firefox 49.0.1

For the past few days some videos will not play in firefox, not on my laptop, my kindle fire and my galaxy 3 phone, and yet the videos work on any other browser (Chrome, Pale Moon, Edge) I have on my devices. It either says, "if playback doesn't begin shortly, try restarting your device" or the swirling circle just keeps on swirling to a black background.

I fix computers for a living and have done all of the standards: restarted my laptop, cleared cache/cookies, tested in safe mode, un/re-installed firefox, my drivers are the way they are supposed to be, ensured my plugins are all active and I had the latest versions of flash, java, and real player.

Then I went up a notch: installed a VLC add-on, disabled hardware acceleration and restarted ff, made sure my firewall and antivirus programs trust plugin-container.exe, and followed the instructions from here: https://support.mozilla.org/en-US/kb/fix-video-audio-problems-firefox-windows,

What gives? And why doesn't FireFox have a fix for this miserable problem?

SOLVED (for me): Installing YouTube Flash Player helped, but only for the youtube video part: https://addons.mozilla.org/en-us/firefox/addon/youtube-flash-player/?src=ss

Going to about:config, and changing media.autoplay.enabled from false to true, then restarting FF, fixed the remainder of the video problem.

I keep getting a screen change popping up on my browser, asking me to install a very important update. I know the patch is a scam, as I've check the internet and see others have experienced the same problem. Is there any way I can stop receiving the firefox-patch.js patch request? It comes up very often when I open chicagotribune.com.

Just upgraded from Exchange 2010 to Exchange 2016, now OWA in Exchange 2016 will not open in Firefox or Chrome, it will open in IE and Microsoft Edge.

Here is the error I get in FireFox:

The website tried to negotiate an inadequate level of security.

my.domain.com uses security technology that is outdated and vulnerable to attack. An attacker could easily reveal information which you thought to be safe. The website administrator will need to fix the server first before you can visit the site.

I have google this for 2 days now and have double check all SSL certs, permission settings etc, and I don't know how to fix this, if anyone has any ideas I would love to hear them. Thanks John

Hi, my Firefox doesn't have support for H.264 decoding, although ffmpeg and other software compiled with support for it. According to https://www.youtube.com/html5 there is no H.264 and MSE & H.264 support. On pages with html5

Only when I'm in firefox, I open a document (doesn't matter what program I'm in), hit print, it automatically downloads instead of printing. I have to go to downloads, retrieve it, then print, and it prints like a bad copy. this has been happening only for the last couple of weeks. I had no problems before that printing. Help!

When I checked this morning, one of my WordPress sites only displayed a few of its images in Firefox, although they all display fine in Chrome, Internet Explorer and Vivaldi. I've tried disabling all add-ons, which didn't help. So I backed up my profile and updated to Firefox 49.0.2, which seemed to fix it. But after about 15-20 minutes, I saw that the problem returned. And there aren't even place-holders displaying... the images just aren't there. Also, when I go to the media library, NONE of those images display there, although their descriptions are all present when I click on them. And if I snag their URLs and enter them directly into my address bar, Firefox displays them fine. I had a friend check with FF too, and everything loaded fine. I'd really appreciate any ideas on where this problem might exist. It seems to only be a problem when FF goes to my pages, because the images will load independently. This has me thoroughly stumped! The site is http://topshelfcopy.com/ and the two large images beneath the nav bar are http://topshelfcopy.com/wp-content/uploads/2016/09/Surf1-cropped.jpg and http://topshelfcopy.com/wp-content/uploads/2012/02/banner2a.gif

I have installed the latest Citrix Receiver plugin from citrix.com, however Firefox does not recognize it. I can get logged in to our storefront server, but when I click to launch the XenApp desktop, FF opens a new tab and goes nowhere. I do not find the Citrix Receiver plugin in the addons manager.

Hi. We have a web application which has a number of <select> elements whose <option> child elements have CSS 'style' attributes to change the background color of some of the options, to make them stand out, like this simple test:

<select name="select">

 <option value="one">ONE</option>
 <option value="two" style="background-color: #00FF00;">TWO</option>
 <option value="three" style="color: #FF0000;">THREE</option>
 <option value="four" style="color: #FF0000; background-color: #00FF00;">FOUR</option>

</select>

This works with older version of Firefox but our users have discovered that the latest version, 49.0.1, ignores the styles for the <option> elements; in the example above all of the lines in the dropdown list for the <select> element have the same default background and color.

Older versions of Firefox show the different colors. Also Firefox 49.0.1 on Windows XP (must be the 32-bit version of Firefox) still does. But Firefox 49.0.1 for Windows Vista and Windows 7 does not show the colors.

Other browsers - Internet Explorer on XP, Google Chrome - also show the style colors.

We standardize on Firefox - we tell our users to use Firefox with our application. If there are no plans to return the styling then we will have to try and replace our <select> elements with customized javascript controls, which will be messy. Or move to another brower, which will take a lot of time in testing. Is there any way/setting to return the old behavior and have Firefox again take note of the 'style' attribute for <option> elements in a <select>? Or might there be plans to fix this in a future release? Thanks!

As the title says, I am unable to start firefox. This happened after a recent upgrade from Kubuntu 16.04 to 16.10. I have attempted reinstalling firefox as well as "libmirprotobuf3" with no success,

When attempting to start firefox from a terminal, the following error returns: $ firefox XPCOMGlueLoad error for file /usr/lib/firefox/libmozgtk.so: /usr/lib/x86_64-linux-gnu/libmirprotobuf.so.3: undefined symbol: _ZNK6google8protobuf11MessageLite39InternalSerializeWithCachedSizesToArrayEbPh Couldn't load XPCOM.

I have bad eyes and at 100% the pages are too small for me to be able to read them. I can use the add-on that allows me to increase the page size to 120% but the minute I go back or on to something else it reverts to 100%. How can I make the increase permanent?

Just want to know how to turn off HTML5 autoplay videos. Also need to know how to allow them when wanted just as Firefox now does with Adobe Flash.

Thanks!

Firefox 49 introduced a new section to the Bookmarks Menu -- both the one that drops from the toolbar button and the one on the classic menu bar. It says Recently Bookmarked and is followed by the five most recently added bookmarks. How to remove it?

(Yes, it's a little obnoxious to create a new question to answer it, but I think it's the best way to help spread this information to anyone searching for it.)

A site I am working on and had no problem loading in the past month suddenly displayed the following error after I loaded a cookie acceptance script in my backend. Tried clearing cache and all history but doesn't work. As this is a commercial site, I need it to work on all browsers. Please advise.

"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."

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"....

FF 49.0.1

I used to be able to simply print a pdf document from google docs or my Etsy invoices. Now, I have to "save" before printing. There have been various updates (I don't keep track,) but I hope somebody can help me just print from my browser!

I have the Firefox 49.o.1 and Windows 7 OS and Adobe Acrobat XI Standard.

I have tried switching the add-ons between the built-in extensions and Adobe's extension.

Any ideas?

Every time I search anything, I always get nude women, men, sexual content. Doesn't matter what words I type in, pornographic content is included in the images window... How do I stop this from happening?
