Firefox does not require plugins to be signed; it requires extensions to be signed. Does Garmin use an extension?

And as far as you can tell, all is well with your Firefox 43?

Firefox 43 is identical to Firefox 44 regarding extensions needing to be digitally signed by Mozilla. This article has more information: Add-on signing in Firefox.

If you are using unsigned extensions in Firefox 43, presumably you have implemented the following global workaround that works in Firefox 43-45:

(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button promising to be careful.

(2) In the search box above the list, type or paste xpin and pause while the list is filtered

(3) Double-click the xpinstall.signatures.required preference to switch it from true to false

Accordingly, it seems that your fury is either misdirected (signing doesn't affect plugins) or premature (there is a workaround for unsigned extensions through Firefox 45).

Please feel free to return and complain about Firefox 46 when that is released and see whether any workarounds are available at that time. Until then, please update.

your answer is partly correct. I am mislead by plugins / addons. I am talking add-on: application/vnd-garmin.mygarmin (Garmin Device Web Control: mygarmin). Apologies.

But, your answer is incorrect as of v44. The xpinstall.signatures.required is no longer available in v44 acordidng to https://blog.mozilla.org/addons/2015/12/29/compatibility-for-firefox-44/

a. Last link has been editied since I last looked. Problem solved. Up until v46 hits the internet, and I will be stuck on exactly the samp problem.

Merci for now :)

There are other things that need attention.

The System Delete list next to your question shows multiple Flash plugins.

• Shockwave Flash 18.0 r0
• Shockwave Flash 20.0 r0

You can find the installation path of all plugins on the about:plugins page.

• http://kb.mozillazine.org/Issues_related_to_plugins#Identifying_installed_plugins

You can check the Flash player installation folder for multiple Flash player plugins and remove older version(s) of the plugin (NPSWF32) and possibly (re)install the latest Flash player.

• (64 bit Windows) C:\Windows\SysWOW64\Macromed\Flash\

You can check the Firefox Add-ons page to see where you find Garmin add-ons. Either:

• Ctrl+Shift+a
• "3-bar" menu button (or Tools menu) > Add-ons

Each list has its own link in the left column of the page. After clicking that, the respective list will appear on the right. For all I know, Garmin has both a plugin and an extension. ??

I saw that, I have uninstalled flash player several times, but it is impossible to get rid of flash player 18. It just stays where it is, and (may I say: as usual), firefox manuals are not for stupid users like me. What I found is what I tried: un-install, re-install. Yet, it remains. Even better, when I switch it off, run the uninstaller a couple of times and re-install, flash player 20 is disabled. I have to manually enable it :(

C:\Windows\SysWOW64\Macromed\Flash\ FlashInstall.log flashplayer.xpt FlashPlayerPlugin_20_0_0_306.exe FlashPlayerUpdateService.exe FlashUtil32_20_0_0_306_Plugin.exe mms.cfg NPSWF32_20_0_0_306.dll plugin.vch

C:\Windows\System32\Macromed\Flash\ FlashInstall.log FlashUtil64_20_0_0_306_Plugin.exe NPSWF64_20_0_0_306.dll plugin.vch

There is no FlashPlayerPlugin_18* anywhere on my system.

If you check the about:plugins page, can you find the path to the older NPSWF32_18_etc.DLL file?

Try to delete the pluginreg.dat file in the Firefox Profile Folder and maybe addons.sqlite as well to reset the plugin registry databases.
