Who thought it was a good idea to limit max width?

This is useless - I have such a large and wide screen, but the extension limits the side view to like 10% of it.

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.

The icon is misleading. I thought it was a means to have a split view, which I would love. By showing the '2nd' window in a side view you cannot compare the two views, since for most sites the phone interface kicks in, due to the prevalent responsive design. (a developer feature - not a user feature - which is quite confusing to most users)

Funciona como queria, obrigado.

Хорошо бы было если бы в открывающейся вкладке была строка, позволяющая открывать сайты напрямую, а не через журнал.

와, 진짜 최고입니다. 사이드 페이지에 열어놓은 탭을 다른 탭에서도 항상 볼 수 있는데 정말 유용하네요.

非常好用,希望能增加 同时滚动功能,add sync scroll

Still has many problems.

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

it is great extension. Can not find nothing like that in Chrome

I had high hopes for this but in its current state, I rarely use it (and just now disabled it). The limit is absurd (hardly any width).

Firefox needs a split screen mode like Vivaldi, where tabs can be split into 2/3/4 screens. Let's start with 2 for now but allow us to remain in our session and not log us out. Let the page not reload just for opening it in a split view. This actually signs you out of the website (the one in the side view). It reloads the tab when you add it to the side view. It's all over the place when it comes to websites where you're signed in.
It's really a very bad implementation and it's clear that care is not given to this add-on, which is unfortunate.

Allow us to split screen an .html file (that I open from my Desktop, which opens in Firefox) with a on-the-Internet tab.

I really want a real split screen add-on, one that also would let us resize to our heart's content and not be limited as we are now. One that displays the tab without reloading, without signing us out, without a new cookie or whatnot. Look at Vivaldi's Page Tiling and imitate that, that's all!

Edit: Use Tile Tab add-on, it's good enough for now but not like Vivaldi's and Edge's implementation, which are the best.

Edit 2 Sept 2022: This broke Asana and it would get stuck at the Download Asana App rather than log me in to the task view.

Edit: July 2024: I tried it again for 2 months but is still breaks websites and also Temu remains in mobile mode. I couldn't figure it out until I recalled that this is active. Deactivated right away. What a buggy mess! Made by Mozilla themselves too lol. Embarrassing.
