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.

HTML styles for <option> elements no longer work with latest Firefox 49.0.1

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!

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"....

I am using Firefox 49.0.1 on WIndows 7 Enterprise machine with dual screen configuration. I have this persistent white bar at the bottom of the window for any websites that I am browsing. Besides the web content, it is covering the down arrow of the scroll bar and any Firefox notifications. I tried disabling add-ons and installing a fresh copy. The white is, well, persistent. This happens only maximised and opened on one of the screen.

I used to be able to use chatstep with no problem. I am using Windows 10. Maybe 3 weeks ago or so suddenly, when I dropped an image into the chat, I got error code 713 image cannot be downloaded. I also cannot receive images from others. I used Windows Edge and I was able to download an image without an error. Therefore, it must be firefox. I also turned off my antivirus and firewall and nothing changed. I tried changing most settings on the page information and that also did not help.

Hi, so I started learning to develop websites a while ago, and all was good. However, recently I've had an issue. When I make a change and I'd like to refresh the page, to see it how someone visiting for the first time would see it, the page reloads, however it's exactly the same. For example, I've got 2 buttons. When button 1 clicked, button 2 gets disabled. Refresh the page and... button 2 is still disabled. In other browsers, both buttons return to their "default state". Shift-clicking the reload button does in fact refresh the page as expected. But a normal click, even if the webpage was retrieved from cache, should at least refresh the page, right? I've tried refreshing firefox, so add-ons are not the issue, and this hasn't been an issue before, any help is appreciated.

I have successfully installed several Add-ons and the "icon" for each one does not appear anywhere (Menu/Customize, toolbar, Tools). However, they all appear in Add-ons. I am reopening this post because the instructions out in Support are too vague for me because I am a basic user and not a developer. I previously posted here and have gotten no responses. I am using Vista and FF Version 49.0.1. I DO NOT want to refresh and loose all my Add-ons.

I did follow this unsuccessfully:

[Exit Firefox completely, then open your Firefox profile folder (read the linked article for its location) and delete or rename these files:

   extensions.ini FOUND
   extensions.cache UNFOUND
   extensions.rdf FOUND

Starting in Firefox 4, also delete or rename:

   extensions.sqlite FOUND
   extensions.sqlite-journal (if found) UNFOUND

You may also need to delete or rename the compatibility.ini FOUND file, to rebuild some other files in the profile folder.

Note: Although the above files can be deleted, renaming them (e.g., "extensionsOLD.ini", "extensionsOLD.cache", etc.) is generally considered a safer option. This achieves the same result, but allows the user to retrieve any possibly required information from them later on.]

I attempted opening the Browser Console and looking for errors but quickly discovered I was in OVER MY HEAD!

Can someone PLEASE HELP...I sincerely appreciate it. Sharon C Wallace

Hi! My favourite browser has been driving me crazy lately (forcing me to use Chrome on my Windows 10 laptop) and my last hope to be able to use Firefox again is to get some answers on this forum. In the past, I'd already searched for help for another issue I had since last year - how to restore previous session when it's grayed out (I didn't want to lose all my tabs), and was very happy and relieved to find it thanks to answers to the questions from other users. I'm one of these persons who tends to have way too many tabs opened. And probably it's because of this huge overload of tabs that my Firefox doesn't work like it should. It would sometimes crash out of the blue, without any apparent reason (and sometimes after parts of pages becoming black and the browser menu flashing and disappearing), and even if it was closed normally, upon opening it again I would sometimes get a "Restore previous session" tab, which wouldn't do what it's supposed to (it would open only blank tabs), so I was manually copying the last good "previous.js" file, renaming it to "sessionstore.js" and putting in the FF profile folder. Oftentimes the browser would work perfectly for a week or 2 straight, and then it would start acting up again, so I had to start fixing it manually again.

But I have no idea what I can do (and IF I can do anything at all) to fix the issue I'm having with Firefox now. I'll describe it in detail below and attach screenshots.

Usually after launching the browser, I see the tabs as "New tab" ones only, I get an "Unresponsive script" warning (this has been happening very often since months - and sometimes it would take hours with "Unresponsive script" pop-ups from various tabs), then, after I click "Stop script", the tabs finally load. But since over a week something strange has been going on: all Firefox buttons are not active/clickable/responsive.

When I click the >, < or + buttons to scroll tabs or add a new one, there's no reaction.

When I click on the "List all tabs" arrow, instead of the whole list I get only "Undo Close Tab" and "New Container Tab" (and tiny arrows above and below them), but neither is responsive. When I click on any other visible tabs to switch to them, nothing happens either - I'm always on the same one.

When I click on the Menu or the Bookmarks icons, the drop-down lists don't appear at all, and when I only hover over them, I see "Open menu", but over the Bookmarks icon a tiny white rectangle appears (just like over the <, > and + buttons).

The Minimize, Restore Down and Close buttons don't work/react either. I can still minimize the window by clicking on the Firefox icon on the taskbar though. If I want to quit the browser, I can only do it from the FF icon on the taskbar (right-clicking on it and choosing the "Close window" from the list).

And when I right-click wherever on the currently opened tab, a very long list appears (not what I normally see, from what I remember).

The current tab however seems to be PARTLY responsive. It's opened on one Facebook post and I see the numbers changing when new notifications arrive (I can also give a "Like" or comment, so it seems to be working). When I clicked on the name of my friend there, it did open her page. But when I click on the "Go back one page" button, it doesn't go back. I can only click on active links (in this case it's pages or profiles names) and go to them, but never go back. However, if I roll over the Firefox button on the taskbar, I always see the title of the tab which was originally opened.

Ctrl click on any link to open it in a new tab doesn't do anything. I also can't close any tabs.

And when I type a new url in the address bar of this one seemingly working tab and hit "Enter" (also the refresh button), it doesn't take me there.

I'm frustrated and fed up with it to the point of forgetting Firefox once and for all. I have no idea what to do. Is there a way to fix this strange error modifying some files in the Firefox folder? Or will I have to uninstall and re-install Firefox? I suppose that's the last resort, but I prefer to ask here first, because I wouldn't like to lose the (way too long) list of tabs I have (maybe I could still copy the old "previous.js" file, rename it to "sessionstore.js" and put in the profile folder of the newly installed FF, but perhaps it's THIS file that is corrupt and causing all this trouble).

Additional information: I see that the latest Firefox update is dated Sept. 25th. This is the last time my browser actually worked (right before the update, I suppose), because the last "previous.js" file I copied was from that date.

I would be really grateful for any help!

I have downloaded many videos using Mac Firefox (current version at the time) and Ant Video Downloader (current version at the time) but Firefox 49.0.1 (and possibly since 49 came out) and AVD 2.4.7.43 don't work together. Everything seems okay until I click the download arrow - then I get a 'flash' of the arrow (normal, suggesting the download is happening) and a single, simple, 6.9 to 7kb download that is nothing. When I use the download arrow to select from the list of 'currently viewed videos' the appearance implies corruption as the 'title' of the movie (say: HOW TO DOWNLOAD THIS VIDEO) is only legible for about half of the title (appearing: HOW TO DOWNL#$#%^&& [obviously garbled characters in a subdued background]). I cannot take a screen shot of this, nor a snapshot (though I guess I could take a picture of the screen with my i-Phone) to show what it looks like. I've updated, installed, uninstalled AVD, then reinstalled it, and installed a fresh download of the entire Firefox app - to no avail. The two have been a perfect wine-and-cheese until the past week or three. One of you - either Mozilla/Firefox or ANT must have a solution that the community hasn't discovered. NO other functions or apps on my computer have been affected.

I just updated Adobe Flash Player to the latest version 23.0.0.185 on my Windows 10 laptop using Firefox 49.0.1. When I ran the test page from Adobe (http://www.adobe.com/shockwave/welcome/), I noticed that the new Flash Player was working, but my Shockwave Player was not. I found a newer version of Shockwave Player 12.2.5.195 and installed that. Still no go. I uninstalled Shockwave Player from Control Panel, rebooted, and reinstalled the new version of Shockwave Player. Still no go. I know this was working the last time I updated Flash Player, which was mid last month. However, it has stopped working. The list of Addons shows the new version of Shockwave for Director installed and active. I set it to always activate, but the test page still shows nothing.

I tried Shockwave in IE, and it works fine there. Does anyone have any idea why Shockwave Player would stop working? Is some plugin possibly blocking it? I do have NoScript but allowed on the Adobe Test page. I also have Adguard which is new, but I see no settings there that would affect it. Thanks.
