how to installed newest version seamonkey 2.49 something?

Its on a 64 bit version OpenSuse

If the latest version is not in the OpenSUSE repos, you should be able to get it directly from the Seamonkey website: https://www.seamonkey-project.org/releases/

See the documentation link in the left sidebar for installation instructions.

i use the contrib 64 bit build
-- requires the 64 bit plugins
https://ftp.mozilla.org/pub/seamonkey/releases/
from there the current 64 bit
https://ftp.mozilla.org/pub/seamonke....49.1/contrib/
or
https://ftp.mozilla.org/pub/seamonke...-x86_64/en-US/

Linux Installation Instructions

There is no installer available, but just extracting the tar.bz2 to the default directory (usually /usr/local/seamonkey) achieves the same result as an installer would.

To install SeaMonkey by downloading the tar.bz2 file:

Create a directory named "seamonkey2" (mkdir seamonkey2) and change to that directory (cd seamonkey2).
Click the link on the site you're downloading SeaMonkey from to download the package (seamonkey-2.*.tar.bz2) file into the seamonkey2 directory.
Decompress the file with the following command:

tar jxvf seamonkey-2.*.tar.bz2
This creates a "seamonkey" directory under your seamonkey2 directory.
Change to the seamonkey directory (cd seamonkey).
Run SeaMonkey with the following command:

./seamonkey

To hook up SeaMonkey complete with icon to the GNOME Panel, follow these steps:

Click the GNOME Main Menu button, open the Panel menu, and then open the Add to Panel submenu and choose Launcher.
Right-click the icon for SeaMonkey on the Panel and enter the following command:

directory_name/seamonkey
where directory_name is the name of the directory you extracted SeaMonkey into. For example, the default directory that SeaMonkey suggests is /usr/local/seamonkey so the full command would be /usr/local/seamonkey/seamonkey.
Type in a name for the icon, and type in a comment if you wish.
Click the icon button and type in the following as the icon's location:

directory_name/chrome/icons/default/default.png
where, again, directory_name is the directory where you installed SeaMonkey. For example, using the default directory /usr/local/seamonkey results in an icon location of /usr/local/seamonkey/chrome/icons/default/default.png.

The procedure is quite similar in the Xfce environment:

Right-click the Applications Menu button, open the Panel menu, then choose Add New Items.
Select Launcher and click Add, then close the Add New Items dialog.
Right-click the new launcher (the one with no icon at the far right of the panel), then select Properties to open the Launcher dialog.
Click the document icon with tool-tip "Add a new empty item" and fill in the Name and Command fields in the Create Launcher dialog.
Name: SeaMonkey
Command: directory_name/seamonkey (e.g. /usr/local/seamonkey/seamonkey)
Click the "No icon" button and navigate to directory_name/chrome/icons/default/default.png. Press OK, then Create, then Close.

seamonkey 2.49 is in the mozilla Repo:
https://software.opensuse.org/package/seamonkey

https://download.opensuse.org/reposi...USE_Leap_42.3/

But less Repos are often more........
