Actually basil you are correct and it was my mistake in thinking it was still in the regular repositories of Ubuntu seems it was taken out because Ubuntu couldn't guarantee 5 year support on it. My apologies here is a better tutorial to follow.

Thank you, lxle, for taking me seriously and following through. Thank you too for the clear and comprehensive instructions for adding a repo which worked first time.

Out of respect for you, this is my first blog interaction on the Web using Seamonkey. So far I am enjoying it, but have a lot of experimenting to do, obviously, before deciding to change lock,stock and barrel. Which reminds me, I have numerous ageing barrels of Opera .mbs files which I would like to migrate to Seamonkey for future reference - does anyone have any helpful suggestions regarding the migration and archiving processes?

And while I am on the journey of discovery, are there any useful comments on Evolution (capitalised, please note) as an alternative emailer from the lxle user community?

Stay strong,
Basil

It remains on the left in our version so you can easily open a new tab and get to your 'Frequented Websites' list without moving your cursor completely across the screen. 'Frequented Websites' is very important in SeaMonkey due to the lack of a built in speed dial as per FireFox or Chrome.

However outside of just moving it far right using a userstyle or right clicking on the tab or tabbar and selecting new tab you could also install https://addons.mozilla.org/en-US/seamonkey/addon/tab-clicking-options/ and then simply set it up so that every time you double click on a tab or in the tab bar a new tab is created.

Just click on add to seamonkey and then install anyway. Should be just fine.

close and forget is already installed be default as well.
