I am excited to learn that FF has this plugin. It ease my browsing experience alot, make it so convenient. But the downside is the sideview width is so limited, or else i wouldn't have anything to complain with this addon

Works well, but could use a button to unload the current site.
Also, pls unlock the max sidebar width.
For ppl with ultrawide monitors that could be a nice alternative to multiple FF winows.
I'd change my rating to 6/5 immediately.

Cool!! I normally use two web-browser side by side... I still think is better option, but sometimes sites get really small when I squeeze the windows, so I switch to mobile view, but pitifully there is no extension to make this by tab and I have to constantly switch the views. Your extension could be a solution for me, if it just had an address bar.. hehe... but I guess other people are looking to put more info in one screen. Anyways it seem great! thanks man

Why can't I zoom anymore? Please fix it.

Great and useful addon, I just wish we could increase to 50% the width of the side view and could go back or forward on the current page as well as freely browse to different websites which are not necessarily in the current tabs

It seems Javascript does not really like running in sidebar as any page I tried have JS not working. Also cookies are not preserved which makes pages asking for l/p on each click. Also FF sidebar which this plugin uses has pretty narrow max width. This can luckily be "fixed" and make it resize without limits by installing https://github.com/Aris-t2/CustomCSSforFx and enable "./css/generalui/sidebar_width_unrestricted.css" (search for "sidebar" in "userChrome.css" and uncomment). Tested with FF 73.

A must-have for me, this is a godsend. Very useful for wide monitors. 4 stars though because I can't extend the width of the side window to more than a fixed width - which seems very arbitrary.

I see 2 serious problems:
1. If you want to use it for Instagram, but you already use Facebook Container, you will have to login again and again.
2. Now you can not just create a folder for mobile websites and use it in sidebar as before, now you have to use context menu every time you need it. 2-3 clicks instead of 1.

Superb! Very useful add-on!
I hope that it continues to be developed. For example, to be able to drag it with no restriction. Or to have multiple pages that you can switch.

Awesome extension! Exactly what I was looking for to watch my email.
Add more futures plz
- open in a new tab not in mobile view
- back button
- multiple side views
- resizable more then 1/3 of a page

could be better if this could be like what tile tabs used to be before quantum also if i could put it at the bottom

Love the concept, but really needs to expand up to 50% in order to be useful. Also, clinking links in the sidebar bar page will actually change the main page, which took some time to wrap my head around. Hope it goes native!

Handy but limited. Allowing wider view (50% instead of 25% of window) would help a lot. Too many web pages are not optimized for mobile view and are not readable when limited to 25% side bar (PDFs opened in browsers, for example). That's available with Tile Tabs WE, but it would be nice to have in Side View to not have to guess how a particular page is going to behave, choose which extension to use, test it, find it's not the right choice, close, choose the other one, etc.

Honestly, works exactly as it was intended and very well at that. If it weren't for two issues, I would give this five stars. These issues are that when the add-on is first installed, it opens up a side bar with your bookmarks and other useful things. After looking around, very shortly, I found that you have to click the icon on the top right to open the multi-view. For a lot of people, this wouldn't be an issue, but for new or inexperienced computer users, this could be confusing and may result in them uninstalling because they think that it isn't working. The next issue being that when I'm trying to install another extension using the side view, the extension doesn't want to install. Other than these issues though, the add-on works very well as I am using it to type this review. Good job!

If you can make this as user friendly and functional as Vivaldi Browser's Side Panel feature, Firefox would be my daily driver. Vivaldi's Side Panel feature is something that I expect and use all the time. And is what keeps me coming back to Vivaldi from all other browsers.
