Firefox side view addon is limited in size, I can't resize it to half of the window, how to fix?

As you can see in the attach picture, I cannot resize the side view window any farther to the right than what it is.

If you are familiar with the optional userChrome.css file, add this code to your userChrome.css file.

/* remove maximum/minimum width restriction of sidebar */
#sidebar {
max-width: none !important;
min-width: 0px !important; }

Set the max-width to your desired width in pixels and keep that !important statement. At none the Side Bar can be dragged to the entire width of the browser window.

And the min-width can be set, too.

You'll have to see if it works with the extension that you are using, it does work with no Side Bar add-on - I just verified that pref is still valid.
