Firefox 30.0a2 doen't recognises flashplayer, but Firefox 27 does

I'm using Linux Mint 15 Olivia, I update my Firefox using the ppa:mozillateam/firefox-next but it only update my firefox to 27.
So I downloaded firefox-aura and intalled it on /opt/firefox-aurora. Now I have both firefox 27 and 30 on my pc. Well my firefox 27 recognises my flashplugin but firefox-aurora not.
It doesn't seems to be a problem with the plugin itself as it works fine with a previous version.
I thought about put the plugin manually inside firefox-aurora/plugins but there isn't a folder plugins, and I don't know if just to create a folder 'plugins' and to put a symbolic link to my flashplayer plugin will work...

Are you using the 64-bit or 32-bit Flash?

I've installed Flashplayer but Firefox acts as if it's not installed

I've just installed Firefox, and so far am loving it. However, I just had to install flashplayer, and Firefox doesn't seem to want to run it.
I've uninstalled Flashplayer and tried reinstalling it, which didn't work.
I uninstalled it then installed it via IE (telling the page to "instal for firefox") That didn't work either.
How do I get Firefox to recognise Flashplayer and use it once it's installed?
Many thanks, I look forward to your help.

A couple of things to check.
Make sure that the option to scan for plugins is turned on, it will be very unusual if it is turned off but worth checking
# Type '''about:config''' into the location bar and press enter
# Accept the warning message that appears, you will be taken to a list of preferences
# Locate the preference '''plugin.scan.plid.all''', it should be set to '''true''', if it is not double-click on it to change its value
The file that stores details of plugins may be damaged, try renaming this file which will force Firefox to scan for all plugins.
This can be caused if one of the files that stores details of installed extensions is corrupt.
# Open your profile folder, for details of how to find it see https://support.mozilla.com/kb/Profiles
# Close Firefox
# Rename pluginreg.dat to pluginreg.old
# Re-start Firefox, it will then rebuild the list of plugins

I have latest version of flashplayer but firefox is not playing you videos

My system details are as follows-
Windows-7 ultimate
flash player, shockwave player, silverlight plugin lates version installed.

Recent crashes of certain multimedia contents (this includes Youtube videos, certain flash games and other applications) in conjunction with Firefox are most probably caused by a recent Flash update and/or a malfunctioning browser plugin such as Real Player.

Firefox does not launch. Process firefox.exe *32 is in task manager, but browser does not open.

Running Windows 7. Installed latest version of Java and Firefox. Rebooted. Firefox no longer launches but does have a process running.

Something is preventing Firefox from loading your profile correctly. You may want to try loading Firefox in Safe Mode with add-ons disabled.
[https://support.mozilla.com/en-US/kb/Safe%20Mode How To Start Firefox in Safe Mode]
Once you're in Safe Mode you can view a list of your plugins in '''Tools > Add-Ons > Plugins''' and disable each plug-in one by one until Firefox can open normally outside of safe-mode. If disabling one particular plugin fixes the problem you will need to uninstall that plugin. You are not able to uninstall plug-ins from within Firefox itself but sometimes they are related to other programs installed on Windows.
[http://plugindoc.mozdev.org/faqs/uninstall.html Uninstalling Plugins FAQ]
Your system details shows that your Firefox version is 3.x however the latest version is 4.0.1. If you're not sure you've installed the latest version you can try downloading the latest version and installing it again.

As a last resort you can uninstall and reinstall Firefox, while keeping existing user settings and profiles, but if it continues to hang while booting, as a final resort you can delete your profile and start over. Take note you '''will''' lose all of your preferences, bookmarks, and stored search queries and passwords.

Everytime I click "Update Firefox," it starts to download said update, but never does anything else. I have also tried completely re-downloading a newer version of Firefox, but that doesn't work either.

I have no more details.

If you have problems with updating or with the permissions then easiest is to download the full version and trash the currently installed version to do a clean install of the new version.
Download a new copy of the Firefox program and save the DMG file to the desktop
* Firefox 5.0.x: http://www.mozilla.com/en-US/firefox/all.html
* Trash the current Firefox application to do a clean (re-)install
* Install the new version that you have downloaded
Your profile data is stored elsewhere in the [http://kb.mozillazine.org/Profile_folder_-_Firefox Firefox Profile Folder], so you won't lose your bookmarks and other personal data.

I have tried removing Firefox but when I try to do that it says that I need to close firefox - but of course it is not open. I have waited a long time but nothing has happened so I am getting desperate Thanks -- Jerry

Do a clean (re)install:
* Download a fresh Firefox copy from http://www.mozilla.com/firefox/all.html and save the file to the desktop.
* Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
* Don't remove personal data when uninstalling.
* It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
You can initially skip the step to create a new profile, that may not necessary for this issue.

Is it this add-on - https://addons.mozilla.org/firefox/addon/screenshot/
Prior to the release of Firefox 5 which is due out on June 21st, Mozilla will be checking add-ons that are hosted on AMO and work with Firefox 4 to see if they work with Firefox 5, and for those that do they will update the compatibility details to let the add-on install on Firefox 5.
If you are happy testing new versions of Firefox prior to the release, you may want to install the Add-on Compatibility Reporter extension - https://addons.mozilla.org/firefox/addon/add-on-compatibility-reporter/
With this extension you can enable all of your current extensions to test them to see if they work with the development version of Firefox.

You must close Firefox to install the update after it is saved to your hard drive. Follow the instructions below.
There are 2 versions of Adobe Flash. Both must be installed and updated on Windows systems. In Firefox it would show as Shockwave Flash in your plug-ins, if you had it installed.
*an ActiveX version for IE only
*a plug-in version for Firefox and most other browsers
#'''Install or Update the [[Managing the Flash plugin|Flash]] plugin''' to the latest version.
#*Download and SAVE to your Desktop so you can find the installer later
#*If you do not have the current version, click on the "Player Download Center" link on the "'''Download and information'''" or "'''Download Manual installers'''" below
#*After download is complete, exit Firefox
#*Click on the installer you just downloaded and install
#**Windows 7 and Vista: may need to right-click the installer and choose "Run as Administrator"
#*Start Firefox and check your version again or test the installation by going back to the download link below

O/s Win XP 64 bit - Java latest version installed but Firefox Nightly 64 bit will not recognise it after re-install 3 times & re-loading FireFox, IE does see it

Although I had Java latest version installed and IE and Chrome recognise it, i can't get Firefox Nightly 64bit to see Java. Websites with Java functionality in Firefox report that i need to install Java.
I re-installed 3 times, I cleaned out older Java versions and did all other steps in Firefox help articles.
If I go to Firefox plugins page, its says the only plugin I have is Shockwave. If I select the Java option, it tells me to download and install Java - which I have done before several times.
I have shut down and re-opened Firefox many times to get it to see Java.
Java is installed to c:/Program Files(x86). Is Firefox looking for Java in c:/Program Files ??
The website in question is the nVidea driver download page at http://www.geforce.co.uk/drivers, where the auto-detect correct driver function is a Java function. In the end I had to use IE to run the Java function.

Ok, one sentence, that's tough - I have gone through the 'firefox crashes when you open it' troubleshooting but my problem remains that firefox crashes when i open it, how do i fix this?

Several days ago firefox crashed when opening and it does so every time i try to open it now. I am able to use internet explorer perfectly. In fact one way i discovered i can still open firefox is by using Advanced System Care (which i installed after the crashing so it was not in any way responsible) and going to 'test bandswidth'. Because firefox is my default browser it opened it up. I was able to enter safe mode in this way and restart firefox in safe mode. I then set firefox so that all plugins and extensions were disabled but this did not help. I am running the default theme. I will be happy to provide any further information if anyone can help..thanks in advance.

Note that the Aurora (28.0a2) and Nightly (29.0a1) build are updated daily and can be unstable being alpha releases. 
You always need to install such a version alongside of the current release via a custom install and use a separate profile for each Firefox version.
Make sure not to start Firefox after the installation has finished and use the Profile Manager to create a new (separate) profile for each version. 
Do a custom install in a different program folder and use the Profile Manager to create a new profile for this version, so make sure not to start Firefox after the installation has finished.

I have the latest edition of the Flash player and it works fine with IE but Firefox keeps telling me I can play things because I dont have it

Since I updated Firefox I cant play anything that requires Flash player. I have the up to date player and it works perfectly with IE but Firefox keeps telling me I need another plug in and when I follow the instructions it says 'download failed try manual download' but even that fails too.
Before I updated Firefox I had no issues, can you help
Alan.

There are 2 versions of Adobe Flash:
*an '''ActiveX version''' for IE only
*a '''Plugin version''' for most other browsers including Firefox
*On a Windows system, you should always update both individually.
'''''You do not appear to have the Plugin version for Firefox installed. ''''' If you did, in Add-ons > Plugins you would see "Shockwave Flash ''(version)''". If "Shockwave Flash" is there and is disabled, click the "Enable" button.
Check your Plugins often --> http://www.mozilla.org/en-US/plugincheck/
*only the most popular/used Plugins are known by this page
*page will detect only installed, '''''enabled''''' Plugins
'''Install or update Adobe Flash''' 
#'''Using Firefox''', go to the following link and SAVE the download to your desktop so you can find it later. Un-check any items on that page that you do not want to download (i.e., "McAfee Security Scan Plus":
#*http://get.adobe.com/flashplayer
#When the download is finished, close Firefox (File > Exit '''''OR''''' Firefox button > Exit)
#Click or double-click on the file you just saved to your desktop
#*In the installation window that appears, click the box to the left of "I have read and...." to place a check mark in the box
#*The "Install" button in the lower right corner will now be highlighted, click it.
#*The installation is quick.
#Start Firefox and test your installation here: https://www.adobe.com/software/flash/about/
#To update/install the ActiveX version for IE '''''only''''', repeat the process, '''but use IE to go to the above website'''.

Firefox won't display a google slideshow, but plays youtube videos, using winxp sp 3 and have latest flash installed.

When you hover over the area where the video should be, it shows a message with info about flashplayer, but doesn't show the video.
The video shows up in Explorer 8 and the latest Safari.
Here is the link for the web page I mentioned.. the video is at the bottom after the text..

I cant see flash files on youtube, i upgrade flash player but firefox disable it because of security, how can i force anable it

I use firefox 3.5.7. I cant see youtube videos because firefox show me an errror that you must upgrade your flash player, I follow the link and upgrade my flash player successfully, but firefox repeat its error massage in restart.
I use firefox help and see that firefox disable my outdated flash player because of safety. I want to enable that plugin
I hope to help me

Hi barb, well for one thing the vs of Flash Player is the old one. You need to update to the latest version which is 10.0.42.34.
The first link should be http://www.gourdlamps.com/presentations; that one and the other one work fine for me.
It could be that those two websites have updated to 10.0.42.34.
Here is the Adobe Uninstaller that you download and put on your Desktop http://kb2.adobe.com/cps/141/tn_14157.html
This is the Installer link for IE and you will SAVE this to your Desktop
http://fpdownload.macromedia.com/get/flashplayer/current/install_flash_player_ax.exe
Then go to this thread and follow my instructions, except use the links I gave you. The procedures are the same.
Before you do any of this, take a look at the Uninstall article and the last two NOTES. They are very important when uninstalling IE. The last NOTE: Use the "See Details" If you see the old version of 10.0.32.18 still there, follow those instructions in that NOTE.
Thread: http://forums.adobe.com/thread/561702?tstart=0 (If you have a problem with the link, look for the thread
"NPSWF32.dll error...." on the first page of the Flash forum.)
Also one other difference is after Adobe confirms you have the 10.0.42.34 installed, you would go to the manage add ons
and look for Shockwave Flash Object.....ActiveX Control......Flash10d.ocx ...... make sure that is listed and it is Enabled.
Java: If you have any old Java entries in your Add/Remove, Remove them via the Add/Remove process, wait until the entry no longer appears and when you are finished, Reboot. You can do this and install the Java before Uninstalling & Installing. Link to Java JRE 6 update 18 : http://java.sun.com/javase/downloads/index.jsp
If you have any questions, just post back.
Thanks,

Cannot download videos
This is caused by the RealPlayer Browser Record Plugin extension. To fix it, disable the extension.
The RealPlayer plugin will still work.
At the top of the Firefox window, click on the Firefox button (Tools menu in Windows XP), and then click Add-ons. The Add-ons Manager tab will open.
In the Add-ons Manager tab, select the Extensions panel.
Select RealPlayer Browser Record Plugin.
Click on Disable.
Click Restart Now to start Firefox with the extension disabled. My add-on manager says the add-on is disabled.
I tried this and it didn't work, what else?

Firefox 30.0a2 doen't recognises flashplayer, but Firefox 27 does
