Why does Firefox say I have an old version of Flash

[Martin_666]

I have just updated Flash. This web page tells me I have Version 19.0.0.226:-

helpx.adobe.com/flash-player.html

and when I checked Internet Explorer and Chrome they concur.

However, if I go to the Firefox Add-ons page it says I have Shockwave Flash 19.0.0.185 and lists the file as:

NPSWF32_19_0_0_185.dll, NPSWF32_19_0_0_226.dll

which looks as if both versions 19.0.0.185: and 19.0.0.226:are installed, with Firefox running 19.0.0.185.

Is this correct?

And, if so, would it help if I delete NPSWF32_19_0_0_226.dll ?

I have the same issue, Firefox (Cyberfox) tells me I have two versions of flash installed.

That's a bug that the developer of flash must fixed.

If Firefox was in use during the upgrade the file, for the previous version, will remain on the system, and marked for deletion upon reboot. However, Firefox should detect the latest version not the previous version.  Based on your most recent post, if you rebooted your system between the time of your first post and your last post, the DLL for the previous version (19.0.0.185) has been deleted.

Cyberfox is not officially supported, as such, it could be behaving slightly different than Firefox, which is officially supported.

I did indeed reboot the machine, so your explanation sounds right. I assume that a bug in Firefox caused it to continue using the old version until I rebooted.

That is a bit worrying, particularly as the latest update was in response to a major security problem.

If Firefox is open during an install/upgrade refreshing the browser (if more than one tab is open, then refresh all tabs) will load the newly installed version.  This functionality has been available in Firefox for several years.  If it's not working, then it's a regression bug in Firefox, not Flash Player, as the browser controls when/how to load a newly installed plugin.

I am having a similar problem with Firefox's reader plugin.

It can't just be Firefox, there must be something else... I removed Adobe reader, reinstalled (and updated from Adobe Reader DC). The plugin is still outdated even after reboot.

Hi jc_artlover,

I don't work on Reader and have no knowledge of how their installer works.  Please post your issue to the Acrobat Reader forum.

Thank you. I will check the Reader forum.

I restarted Firefox a few times to no effect - but today, for no apparent reason, Firefox shows version 19.0.0.226 and the old file NPSWF32_19_0_0_185.dll has vanished from my hard drive.

Since I let Flash player auto-updating, I get no problem and I don't have two different versions of flash installed. I have only the latest one.
