Firefox Support Forum

Every time the player is on focus and you press a key to change the volume on Firefox 37+ this includes the new Firefox 38 as well it makes the plug-in handler to hang alongside with Firefox till you get the option to close it or wait if you keep waiting it will stay frozen till you get the same option again and close it.

This was tested on clean profiles with no add-ons or changed preferences, keyboard or it's drivers have been tested and have nothing to do with the issue, different flash versions were tested and flash was uninstalled and reinstalled using the program adobe provides with it's guide and nothing changes also this issue doesn't happen on firefox 36.0.4 or older versions so it's for sure an Issue with firefox 37+.

OS: Windows 7 x64

I want this to be acknowledge by developers so they can solve it I'm not sure if this is the correct/acceptable place so let me know and please point me to the appropriate place if this is not the one.

I love Mozilla Firefox, I don't want to move to Chrome, but there is a point where I can't keep wasting my time to fix stupid problems with flash player when it works perfectly on the other browsers... Tried everything that was recommended at least 10 times, still the plug-in keeps crashing...

I have: Firefox 38.0.5 Shockwave Flash 18.0.0.160

Problem is that when I watch a video that is NOT in youtube, there seems to be no sound. This happens on sites such as: twitch.com kissanime.com (In this site the have the option to play videos in HTML5, which works fine) and website with flash games like: kongregate.com

Sound is faint on You Tube and some other videos, but ads are still loud. The exact same You Tube video will sound loud in IE. This is an ASUS laptop with Windows 7. I have Silverlight already (just checked.)

my videos would not work. so I went to the memu. then than add-ons. clicked on plugins. then downloaded the adobe flash player download was appilyed but in the bottom right side it had a green box and in it had 9.99 a month. I did not click on it. Tried to remove it from my computer . do not know if it removed it. just wanting to know if the adobe flash player is free the version 18.0.0.199. if not how to cancel it? first time trying to fix the problem myself. I was told if you have to pay for it you will have to put in some way of payment for it or you will get it for a little while to try and then you will start paying for it.

Flash Player Plugin 16.0.0.235 won't uninstall from firefox at all ! I tried the download uninstaller and it says it successfully uninstalled it. But when I go to look in the plugin section in firefox it shows it's still there. and firefox had me updated it so now theres two version of flash player plugin ! you guys really need to redo firefox from scratch.. cause this browser really has loads of bugs and errors for small plugins like flash player to screw up from. and this happened more then once to me in the past few months. your people have firefox set to block a version of flash player and then we can't uninstall it ! cause your browser program has errors. instead of blocking the flash player bad version just have us update it and uninstall it . so there won't be any more uninstall errors. if this keeps up with firefox having all these problems I really can't wait till a newer browser comes along and boots firefox off the market for good. and I am glad that firefox is free, cause I really would of hated to spend money on something so crappy. and crashes that firefox does some times is pathetic ! and it freezes up too. and by the way I also tried to uninstall firefox in safe mode and re-install it after rebooting the pc. and every thing was back on firefox even my favorites and "YES" the Flash Player Plugin 16.0.0.235 which was supposed to been uninstalled already. you guys should have so when we do uninstall of firefox it uninstalled all folders and registry as well of firefox. so a fresh clean install of firefox can be done. I even deleted in the registry of Flash Player Plugin 16.0.0.235 ! but it still shows up in firefox plugin section.

cause of firefox's errors and stuff I downloaded cyberfox which works better then your new version.

its the only way I could be able to post my question on the board here, cause firefox version froze up on me cause your Flash Player Plugin 16.0.0.235 Error. so like I said if I was you firefox programers I would start the entire program from scratch ! and watch your coding errors too. cause thats were its all coming from.

In the last versions of Firefox i found some problems, the last one is all my videos in the youtube stay in low resolutions and i cant change that in the resolution settings. I figure out you just fix the gifs problems in vine and twitter and now it looks fine and the animations playing good in this last version i update today.

i am not able to play videos from any source. i have upgraded firefox. updated all of my plug-ins and add-ons. removed and replaced quicktime and windows media players. i am able to play videos on internet explorer, but not on firefox. i have been a firefox user for many years, but this suddenly happened today. in addition, when i open my own website on firefox, the background color is missing, as well as the boxes that frame the drop down menus. these do appear when i open my website on explorer.

i have tried everything i can possibly think of, as well as anything i could read in support.

the "rotating wheel" that shows when something is loading in windows vibrates erratically when a video is trying to load.

I kep getting the message that Adobe Flash needs updating but everytime I try to update by following the links I get nowhere. I ened up with a screen showing a spinning line (?); this remains for up to an hour at which point I gave up. What can I do to update this add-on please?

При просмотре любого видео или прослушивание музыки, браузер начинает все больше и больше использовать оперативной памяти пока не достигнет ее придела тогда происходит зависание его. Что делалось: 1. Отключались все плагины и расширения не помогло 2. Обновлялсь Flesh player к самой новой 18 версии и старых 17-16 таже не помогло 3. Обновлялсь также и браузер до 39 версии также без результатно

I have a quite low end system set up, so I'm not expecting miracles from it, but there seems to be some problems playing Youtube videos on Firefox.

If I load a video on Internet Explorer, it will play fine, even on 1080p with CPU usage of about 20%. Firefox often exhibits problems playing videos.

If I launch Firefox immediately from signing in, the videos will play fine. If I navigate to another video, there will usually be dropped frames and high CPU usage.

I understand that Internet Explorer will use the h.264 codec which is GPU accelerated whilst FF will use a more CPU intense task, but that doesn't really explain why sometimes the videos will play fine and others, it won't.

I have tried on a completely clean install of Firefox, so it will unlikely be extensions, profiles or add-ons. I have then changed the timing of the sessions saving and disabled smooth scrolling as advised elsewhere, with no success.

All help gratefully received.

I have the latest version of Adobe Flash installed 18.0.0.203 - this is confirmed on both the adobe site and the Firefox add-ons page. Yet, I continue to get the message saying Flash Player is vulnerable...

I've been having this issue for a while now and while it was fixed for a while with a plugin (Link Here: https://addons.mozilla.org/en-us/firefox/addon/youtube-all-html5/ ) It recently came up again when Firefox Blocked Flash (as far as I'm aware, that's what happened). This made the HTML5 plugin stop working for some reason and I had to re-install flash and the plugin to get it working again.

When this issue first appeared It was only solvable by using this plugin, and I don't know why. I tried running Firefox in safe mode, refreshing firefox, and uninstalled/reinstalled firefox and I even completely deleted my profile/all my settings, etc. Nothing worked. I don't know what could be causing this issue, because without this plugin HTML5 videos simply do not work. I'm hoping to have this problem solved before it shows up again and the plugin can not fix it. Thank you in advance! -kenny

I hate the new built in flash blocker, too much trouble to allow and disallow for certain sites and NO way to just allow for parts of a site.

Is there a way to disable it entirely? And, hopefully, allow the good old flashblock add-on that worked FLAWLESSLY to work again?

I don't understand why developers make changes that violate the old saying "If it ain't broke, don't fix it.".

I have to reinstall Adobe Reader several times a DAY on Firefox. I have sent a crash report EVERY SINGLE TIME. Why does this keep happening and why does it only happen on Firefox?

Windows 7 and Firefox have issues with Adope Flash... Flash continuously eats up processor resources and increases the processor chip temperature.. Also, there is a related memory leakage issue...

To address this issue, Ms said upgrade drivers and Firefox said install "Flash Block", which allows you to turn on any windows / frames using Flash as needed. Since Flash is mostly used for anoying advertising and pop ups, it seemed the correct course of action.

However, the first call I made using Skype thereafter, the person recieiving the call said they could not hear me... Same result with calls to other numbers.

Is Flash an integral component of Skype? And if so, what is the fix? as no manual offer to turn on the Flash for Skype. I tried white listing Skyp in FlashBlock with out good result..

Please advise.
