But some readers, including myself [even though around since
Netscape 4.x], do not.
Could you point to an official definition of the terms "plugin"
and "extension"?
I for one have never seen the need to enhance in any way a
standard release. I explicitly disable some longtime features
such as cookies, JavaScript, and site specified colors/backgrounds.
Go to <https://en.wikipedia.org/wiki/Plug-in#Computing>. There are four
bullets; the first two are relevant.
Thank you. When I said "official definition" I should have said
something like "How does SeaMonkey (or Mozilla) define the
distinction between a 'plugin' and an 'extension' ?"
From actually using both plugins and extensions, the Wikipedia
description reflects reality. When I open the Add-ons Manager, the
items under Extensions are indeed as described in the second bulltet on
the Wikipedia page; and the items under Plugins are as described in the
first bullet on that page.
So when a plugin crashes ... the browser is still alive.
When an extension crashes... the browser crashes.
Am I wrong ?
I think that is correct.
A plugin is installed separately and independently of the browser or any
other application that might launch it (e.g., Thunderbird). The browser
launches the plugin to perform some task. I generally download plugins
via SeaMonkey. When I install a new plugin, however, I do so with
SeaMonkey terminated. The same plugin -- not a separate installation --
can be used by other applications; it is not installed specifically for
each application that uses it.
An extension is installed into a browser's profile, changing the
internal code of the browser when that profile is active. I just now
installed an update for the Theme Font & Size Changer extension. I had
to install it five times, once for each of four SeaMonkey profiles and
once again for Thunderbird.
Soooo .... A "Plug-in" is applied to a *SYSTEM/O.S* where as an
"Extension" is applied to a *Program/Browser*?? Yes/No!!
Yes.
Thank you .... but that then raises the question If Plug-ins are System
wide, why are they shown with-in a Program?? Or is this suggesting that
these System Plug-ins are being used by this Program ... but none of the
other plug-ins install on this OS are being used by this Program??
Plugins may be USED by SeaMonkey but do not change the code the way
extensions do. If you want to see which plugins are really used by
SeaMonkey, on the SeaMonkey menu bar select [Edit > Preferences]. Then
on the Preferences window select [Browser > Helper Applications]. None
of the indicated applications are extensions; they are plugins.
So if Tools->Add-Ons Manager (about:addons) shows I have ...
1 *Always Activate*
a. Adobe Acrobat
b. Java (TM) Platform SE 8 U73
c. RealJukebox NS Plugin
d. RealNetworks(tm) Chrome Background Extension Plug-On (32-bit)
e. RealPlayer(tm) G2 LiveConnect-Enabled Plug-In (32-bit)
f. RealPlayer(tm) HTML5VideoShim Plug-In (32-bit)
g. Shockwave Flash
h. Shockwave for Director (11.5)
2 *Ask to Activate*
a. Java Development Toolkit 8.0.730.2
b. RealPlayer Download Plugin
c. Shockwave for Director (11.6.8.638)
whereas in Edit->Preferences->Browser->Helper Applications, I have ...
a. Adobe Acrobat Forms Documentation (app/vnd. adobe.xfdf)
b. Adobe Acrobat Forms Documentation (app/vnd. adobe.fdf)
c. Adobe Acrobat XML Data Package File
d. AVI video
e. Podcast
f. QuickTime video
g. Rich Text Document
h. Vidoe Podcast
i. Web Feed
j. Windows Media video
plus various others set to "Save File", "Always Ask"
How does the Tools list crossmatch with the Helper Apps listing??
