I use firefox. Ever since firefox 47 came out. I have not been able to access anything with flash content. Can't play games on facebook, can't watch videos(except youtube, as they use HTML), or anything else.

The only way I can do that is to use chrome. Flash crashed before on FF, but NOT THIS BAD!!

Try Flash before restoring with MozBackup in case there is something in there that it doesn't like. Note also that MozBackup is no longer supported so it might backfire on newer Firefox versions. You can save your profile manually and the bookmarks.

Hi, there, T-R-A, thanks for your quick response.

And, yes, I did try all that. But, just now I saw 'turn off hardware acceleration'. I don't think I did that before, so tried it, but, no joy.

I also tried the newest version of FF, which was released the other day, same thing.
And, I tried older version of flash, with FF 48(newest v.), same thing.

Then I tried FF 46 with older version of flash, I think, no dice.
Then I tried FF 46 with latest current flash, no dice, except for I can watch some videos on facebook now, which I don't think I could do before.
I tried troubleshooting extensions, esp. the ones which seem like it may be the cause, but didn't help.

I have no idea what to do. I know that I cannot update my graphics driver, and cannot get a new video card, as it is connected to the motherboard. Oh, and, BTW, this is a very new motherboard, from 2/16, as my old one died.

Thanks for the advice, but ???????? What can I do now?

Just curious, have you tried a portable version of Firefox (you can install it on a USB drive and keep your "hard-disk" version as well):

NB...You may have to uninstall/reinstall flash again if you try this version....

No, but that's OK. I don't have a flash drive. I guess I could get one, but, um, what's the difference? I mean, sorry, can't see the advantage to it.
Can you possible enlighten me? Thanks.

Also, can you tell me, by any chance, what it means by 'relegate flash content'?
I was looking at pcmag review of FF48, & he said that was the biggest change since the last version?

Thanks for any help you can give me!!!

The portable just runs as a file from where you've saved it, rather than it being installed which is more integrated. It could make some difference.

I assume you've run without Firefox extensions, open with shift key held down or add -safe-mode to the shortcut (one space before the first minus sign). It's not that it should be necessary but if it works then it might tell us something.

You could also try Firefox Refresh if you haven't already:
https://support.mozilla.org/en-US/k...

Mighty strange this because many folk including me are running Flash with Firefox. I don't like to suggest registry cleaners to people but I suppose removing Flash then running the CCleaner registry cleaner might help - re-install Flash afterwards obviously.

Did you check in Firefox Add Ons to make sure that Flash Player is enabled either by default or by asking?

I had some problems recently with Flash content (graphic ads) swamping Firefox and either lowing, freezing, or crashing it. I set Flash Player to always ask and the problem disappeared. I can enable it for a page but the junk ads that over use it no longer come up and my problems with it were solved.

Try running Malwarebytes, Adwcleaner, and JRT - junkware removal tool to make sure some of the junk is not affecting Flash & FF.

You have to be a little bit crazy to keep you from going insane.

Hi, Derek,

I think I did try that before, starting FF in safe mode, but I just tried again, and Facebook games still doesn't play.

I believe I refreshed FF before, too.

But, thanks for caring & trying to help!!

Hi, Fingers,

Yes, it is set to always activate.

I have MalwareBytes & run every 2 days. I'll try AdwCleaner & JRT.

Thanks!!!

Oops, I slipped in #5. You would obviously have to keep Flash running, so rather than starting Firefox without extensions try disabling all extension and plug-ins except Flash (if you haven't already).

ADWCleaner (already given) is particularly good at unearthing browser malware. Sometimes MalwareBytes can miss that. It is usually safe to run the Scan followed by the Clean.

Hi, Derek, been busy, so, sorry didn't answer till now.

Anyways, I believe that the addons are disabled, but not extensions, so flash is available. But, that didn't help.

I ran AdwCleaner & JRT, but, that didn't help.

Also, the other day, someone on a chat site I visit was saying that the prob could lie with the 64 bit version of FF. I wasn't sure if it was 32 or 64 that I had d/l of v. 48. I actually thought that ALL the FF versions now, since several months ago were all 64 bit. But, I know I d/l a 32 bit version of FF 48.

Well, thank you for your assistance in trying to help me with this. But, unfortunately, I am, well, with a flash player that always wants to crash!! LOL

Quite a mystery then. As you probably know, 32 bit program versions usually run fine on a 64 bit machine. It rather points towards Firefox as it runs on Chrome. Does Flash run OK on IE?

What are the symptoms when Flash crashes - does it just stop or is there an error message?

Are you running Adblock Plus?

Hi, Derek,

Yes, flash works in IE as well.

When I try to play a game, etc., it will not load anything, and there is the page with Flash player has crashed, to submit crash report, etc. Nothing unusual. I watch, and I know that it's crashed when it doesn't progress to open game or whatever.

I run Adblock Plus, yes, but I just tried disabling it, but, no dice.

Seems it must be Firefox related though goodness knows how.

About the only thing I can suggest is to save your bookmarks somewhere then uninstall Firefox using "Control Panel > Programs and features". You can then run an uninstaller program so that any remnants are also removed. Revo Uninstaller free version (bottom of page) used to be for 32 bit only but that is no longer mentioned so it's worth a shot:
http://www.revouninstaller.com/revo...

If not there is IObit freebie:
http://www.iobit.com/en/advanceduni...

If you happen to use CCleaner you could run it and let it remove any remaining Firefox registry entries (although the uninstaller should do that).

You then restart the computer, install the latest Firefox and hope for the best.

Hey, Derek,

Well, I did that before, too, but, I'll make sure to restart before installing FF again.
I use MozBackup to well, make it like I like it again. And, I use WiseProgramUninstaller.
I like it since it removes registry entries. Used to use IOBIT uninstaller, but decided to give that up since it spies on you.

I'll give that a whirl, and let you know how it goes.

Thanks for caring!! Yeah, wish I knew what the heck is going on!!

You said you had turned off hardware acceleration. Was that in Flash or Firefox?

If you didn't do it in Firefox give it a whirl - it might be more to the point than disabling it in Flash as this problem only arises in Firefox:

Hi, Derek,

I fell asleep last night, so I have to try refreshing & d/l today.

But, will try that, thanks, I mean about Flash.

And, I know I turned off hardware acceleration in FF. I just disabled it again using Chrome. I can't even access flash settings with FF.

Will write when I have set up FF again.

Thanks for the tips. Hope something clicks.

Well, Derek,

Guess what, I refreshed FF, tried using Flash, but, no, I do not think it is MozBackup's fault. Facebook game STILL crashed.

Do you think refreshing is better, or just as good as uninstalling & reinstalling FF? Well, maybe it is, as, I noticed when I reinstalled it, my FF got set up the way I had it, with extensions, etc.

Is it possible using system reset(win10) will help? I had a couple of problems in early July, a little while after FF 47 came out, did a system reset & it fixed the ones that were really bothering me. But, then again, could the reset have caused the problem in the first place? Just wondering.

Thanks for your help. Gosh, I though for sure this would do the trick. Aw, well. That's OK. I still have Chrome if I REALLY want to watch or do something.

FF Refresh is just less disruptive. Nothing can beat FF uninstall, especially if using a program to clear the remnants.

As long as you've tried hardware acceleration Off and On in both Firefox and Flash then I think that idea is done to death.

Much as I'd like to help I've run out of ideas. I still feel FF is number one suspect and in the unlikely even that I suddenly think of something then I'll be back.

Good luck

Thanks, Derek,

I understand. Yes, it is soooo weird. I mean, previously, with a new version of FF, whatever I was having trouble with in the older version, the new one fixed.

The only other thing that I believe,not real sure, was said in the Mozilla forum in reference to this was a windows update for Flash.

Well, anyways, I'm game. I WILL try uninstalling FF. If that did anything, I'll write here.
If you don't see anything here by, say, tomorrow evening, you know that it didn't help.

But, appreciate you trying to help me sort this out. And, if worse comes to worse, although Chrome has SO much junk that comes with using it, which is one of the reasons I don't like to, well, I have IT.

Thanks so much, Derek!!!

For IE11 Flash updates are part of Windows 10 Updates. Maybe that's what you were reading about. Windows update does not get involved with updates for Flash for non IE browsers. For those you must get them by using the browsers in question from here:
http://www.adobe.com/software/flash...

Note that the above tells you whether you are up to date with Flash on the browser you are using, gives you a table with the versions necessary (see Firefox - NPAPI). You can go and get the update from the blue link marked "Player Download Center" in the text just above the table but in FF you have to download the little file and Save it somewhere. Double click the saved file to go online and get the update. Careful to uncheck all the rubbish they try to foist on you (unless you really want it).

The above is worth checking because Chrome uses its own embedded version so there is a vague chance you might not have the version for FF that you think you have.

I was about to say something similar. Way back (pre Chrome, XP era) I had to install Flash for IE and install it again for FF in order to use it with both. This means going to Mozilla site from within FF and downloading the latest installer from there and installing it. The download installs the correct version for your browser you are using at the time and installs that with the correct add on connections.

Hi, guys,

OK, I understand, but I did that before, esp. after uninstalling the old version of Flash I tried out. Do I need to do it again? And, my plug in IS for the version of Flash I am running.

Thanks!!!

If you are going to uninstall and install Flash again then go to this website "from Firefox" and get the full file (19.1MB) rather than the normal small online installer - it might work out better:
https://helpx.adobe.com/flash-playe...

See item 8 in the above link, below where it says "Still having problems". I realise it says Windows 7 at the top but I'm sure it is still OK to use the Firefox file download (Flash for IE being part of Windows Updates on Win 10). It is current version 22.0.0.209. To avoid Win 10 querying it, before double clicking the saved file to right click it, go to Properties and put a check mark in "Unblock". Apply/OK your way out.
