For any one want to remove the width limitation: https://superuser.com/questions/1276800/customize-the-maximum-width-of-the-firefox-sidebar

nice feature, but why doesn't this add on get any updates

Very useful to the browsing experience, great addition to an already exceptional browser!

Wide monitor support, Please allow side view resize to any size of user choice, many have a wide monitor and max width is too small

but cannot adjust width...wait for next version.

Remove the width limit and allow changing the zoom level on the sidebar please.

Yup.. this takes up 10-20% of your screen making this utterly useless. WHY would ANYONE make this garbage tool. I can see the use of this for stock tickers.... maybe... that's about it.

An extremely useful tool, similar to Vivaldi's "Tab Tilling" function but inferior, because it is extremely limited and the size of the window is exaggeratedly small, still, it fulfills its function and I hope Mozilla will update this add-on again.

Sehr gute Idee aber noch ziemlich schwach auf der Brust. Wenn ich mir andere Browser angucke machen die sowas bereits out-of-the-box. Hier ist viel Potenzial drin.

it works pretty well but there should be short cut to access it quickly and adjustable size should be more .

Ok

The idea is great, but 540px as max width of the sidebar makes this extension useless for me. What's the problem to remove this limit? x2

It collides with youtube music. And I use youtube music often, It makes the music stop If you go on another tab and the volume slider and some buttons are gone. Other than this it's nice.

EDIT: I right clicked Side View Extension button and changed site to Desktop version, it worked.
