Rated 2 out of 5 stars
after installing and restarting thunderbird, i had to double right-click to see the contextmenu.
also, there was no suitable link to click to open the link under the cursor.
deinstalling it and it was the normal one-right-click again.
the full-path-to-browser does not have a browse-feature. user has to know and type the path. yak!
also, the mentioned portable %drive%-variable doesnt make clear, if the variable contains :\ so the user has only to enter %drive%path, or %drive%:\path ....
2 stars for the good idea.
minus 3 stars for the userunfriendlyness.
Context menu? Are you sure you are reviewing the right addon?
It's just %Drive%\path-to-browser. I thought that would be obvious enough.
