Nos primeiros dias de uso esta funcionando normal mas uma coisa que notei é que expande ate um certo ponto ,no tamanho de uma tela de celular, aos desenvolvedores analisem isso e permitam expandir mais a tela, fora isso a extensão esta boa

Please make it controllable sizing!

I like the add on but one issue I have is when I have instagram.com in the sidebar and am dming someone whenever I hit enter it goes to a new line and doesn't send the message. When i am in normal browser after I hit enter the message sends.

Good plugin; really nice to use with Wa, Fa and Telegram. Problems:
1) Missing shortcut to open the last webpage used in "Side View"
2) The size of the sidebar is too small and need to be increased when the plugin is installed

Very useful addon but better if it can bookmark the websites for open.

I appreciate this add on for securities research although increasing to 50/50 split would make this a five star (not sure the reason with limiting the size).

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

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

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.

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!

今の所快適です。
早くきちんとした機能としてこれが実装されてほしい。調べ物をしながらYouTubeを見るのに便利です。
私はuserChrome.cssを使ってサイドバーの幅を可変にしています。

ただいくつか要望があります。

・コンテキストメニューは通常画面の方と同じ表示にしてほしい。
せめて「進む／戻る」が表示されていたらもっとページ遷移が楽になるので。

・横方向にはみ出した時、横スクロールバーが表示されません。

・firefoxを閉じた時、その画面を残すか選ばせてほしい。


……自分の場合スライドバーは元々ブクマの表示をメインにしていたので、スライドバーを使いつつ画面分割できるのが一番の理想ではあります。
画面分割できるアプリはありますが、JavaScriptを使ったページ（Google翻訳など）だとうまく表示されませんでした。
画面分割機能も開発お願いします。

Great addon. Some missing option to perfection : some buttons (back, reload) and capability to display more than 25 % width.

nice idea and for a developer it's really helpful. it would be nice if i can open whatsapp messenger on side bar. right now it only show the whats app web page.

One of the best feature. It should have made to the final release of firefox. It would be great if it had dark mode to be consistent with whole browser.

Instead of this being just a side bar, I want this to be able to use Mobile version of a website (it can do this now... but) + the ability for this to be a a split window. I know this is currently an extension, but the whole idea about using this as an experimental extension is to see if this feature makes sense to be in Firefox natively right? I would want this natively in Firefox if it can work as a:

1. Side view exntension's current capability. Don't remove mobile website invoking capability of the extension. Amazing for testing and other mobile oriented experiences when needed.
2. If it can also work as a split window natively instead of having to rely on an extension.

Need to keep improving and having updates. Messenger Facebook is inaccessible!!!!

No doubt that this is a great addon, and very useful.
There should be some option to go back on the page as main back button doesn't work with sidebars, that's why I removed one star. I understand this still is a pre -release version so may be they resolve such issues before final release. Thank you Firefox.
