Adobe Flash player Crashes

I don't like the animation firefox's using to go fullscreen. I disabled "browser.fullscreen.animateUp" by changing value to zero. Now the problem is I don't see tab bar when I hover mouse on top of screen. This option is not simply disabling the animation but also my access to tab bar in fullscreen. Is there a work around? Thanks.

I use FirefoxDeveloperEdition 40.0a2, with OSX 10.10.3. After I set a youtube video to full screen and then return to normal view, the toolbar ( Bookmarks ) is gone. Everything is still set the way it is supposed to ( display toolbar and so on ). After I restart firefox everything is back to normal. I removed all disabled all addons, but it did not change anything. Any Ideas how to solve this?

Hello,

I've been using my own Sync 1.5 server since January without having any issue until this week.

I am unable to sync my clients, getting the "Sync encountered an error while synching: Unknown error, Sync will try again automatically."

Here's the log: https://pastebin.mozilla.org/8836193

The problem seems to happen at line 101 (on pastebin).

Here's some more info about my setup.

Syncserver 1.5.2 installed on a local server running on Linux.

I have 1 Windows client, 2 Linux clients. None of them can sync. All uses Firefox 38.0.

Any help would be appreciated. Thanks, Phil

The Reminderfox add-on is in my profile, (Users\AppData|Roaming) but it is not in my add-on or extentions list. I lost it during the day, while I haven't updated anything or closed Firefox. One minute the add-on was there, the next it was gone.

Every time I restart my MacBook Pro running OS X 10.10.3 Firefox spontaneously opens to the file:///Library/Application%20Support/Adobe/Help/en_US/Dreamweaver/9.0_Extending/help.html?content=dwr_floating_panels_fp_12.html URL.

I have no idea why.

It seems to run normally otherwise.

Is there some way I can stop this?

I am running Firefox 38.0.5.

So every once in a while, I have a bunch of tabs open, FF freezes up and it restarts or Windoze forces a restart. Fine except when an an FF update is staged, or like this time, I lose my 30-40 tabs because I apparently need to know that Pocket has come to Firefox. Restore previous sessions grayed out, I seem to be toast. Getting sick of it now, losing most are fine but I really wanted some of them sitting there without having to be bookmarked, Any way of getting my tabs back when this happens almost once a week now?

Hi and hello!

I am on a Macbook Pro laptop from 2015

Whenever I attempt to view something off Netflix I keep getting error code F7121-3078 :(

Similarly, when I attempt to view Amazon Prime Video it says "We're experiencing a problem playing this video."

I followed instructions, I updated my mac itself to Catalina 10.15.3 and reinstalled Firefox so it should be 100% up to date.

still didn't work.

I read somewhere in this forum from a January post if I open Firefox in 32 bit mode after selecting command + i that it should work but I didn't have that option. I opted for the low resolution setting I saw and not only do the videos still not play but now it looks like I need glasses more than I really do :p I'll be changing that back asap.

What's the vibe check on this? Is there a resolution or a possible ETA of a resolution? Anything?

Any info would be grand!

HEY! Are you going to fix this problem? It's been nearly a month and no solutions!? It's a really big pain and I will just use another browser if you aren't going to fix it. Please send an update SOON.

Just switched from XP to Win 7 Pro. Installed Firefox. When trying to view a composite reflectivity loop (animated weather radar image) on the National Weather Service site, I get an error message that a plug-in is missing, but no other details.

Thanks,

I've used duolingo via firefox for months. Today the sound effects stopped working. They work fine on Safari. Firefox is my preferred browser, but I'll switch if I have to. Thanks

Just recently I started having a problem (in the last week or so). I set my default Amazon kindle device. I buy a Kindle book. The default kindle device is reset (none of the devices are the default one). I have cleared cache and history. No affect. Tried this on another PC and got the same error. Tried it in IE and no error - default device remained set. So there is something in maybe the latest version of FF that is causing that default device setting to be lost? (I have not been able to determine exactly where the default Kindle device setting is kept, but it seems to be in the browser since FF does not work and IE does work on my PC).

As of now sidebar for history and bookmarks is appearing on left side of the window, but I'm observing that it is not useful for me. I would like to have it on right side of window. Can anybody tell me how to do it?

Firefox at latest level 38.0.5 and "Shockwave Flash" at 17.0.0.188...have reinstalled flash so many times now, it's so frustrating. Have also disabled protected mode AND unchecked hardware accelleration, but still have same inssue after re-starting Windows 7 PC 64 bit. Thanks for any suggestions of what to try next..... maybe use adobe flash uninstall utility and instructions https://helpx.adobe.com/flash-player/.../uninstall-flash-player-windows.html and then try another fresh install after shutdown and reboot ?

I am using Ubuntu 14.04 with Firefox 38 and since I updated to that version of Firefox I am unnable to use SoundCloud and TuneIn Radio websites.

On both websites I get the error: media resource ... could not be decoded

I already checked this post (https://support.mozilla.org/es/questions/999164) where somebody had the same problem on Win 7, Firefox 28, but the answer there is not possible for me as my firefox doesn't have those configurations :(

I also disabled all of my add-ons, but still not working :'(

Any help, is welcome :)

Using google it always provides a list for the requested search item. Since yesterday it does not begin and times out. If I use yahoo this does not happen. I also updated firefox but still have the same problem. How do you update google maybe this will help?
