Works well, but two changes would make it more useful:
1. Option for a sidebar home page so that, for example, a news site could appear when firefox is started rather than having to first right click a bookmark
2. Clicking a link would display in the main window rather than in the sidebar. So if I want more detail on a news story, I see it in its intended format and I don't loose the original content of the sidebar

Works great! Small feature but it's fantastic! Please make a white icon for Dark Mode. Many thanks to the developer!!!

Очень ограниченное по функционалу дополнение. Не хватает возможности открытия в Sidebar текущей открытой вкладки и закладки. К тому же открыть в Sidebar можно только одну страницу и если Sidebar закрыть, а потом снова открыть, то открытая страница перегрузится. Я надеялся что это дополнение реализует функционал вэб-панелей из Vivaldi, но этого не произошло.

It works as it should work but 2 options are missing that I consider to be very important:

1- To be able to clone the main browser window to the sidebar without having to do it from the link, that is, from the contextual menu of the Web page
2- Allow the use of extensions (Ex .: translator) as if it were the main browser window. It is very annoying not to be able to use the translator in the sidebar :(

It's working well.Thank you!

Bravo!Well done!

it's exactly what i need

Great!!!

Would be nice to have a button to "send current page to sidebar" and also a context menu entry to allow bookmarks to be loaded in the sidebar as well!!!
