I have long been a fan of Firefox; recently I have decided to give Chrome a try. I am hoping that Chrome has some equivalent to loading a bookmark in a sidebar. Not the bookmarks menu, but the bookmarked page itself, like Firefox does. For example, sometimes I want my Esperanto dictionary open in the sidebar while I browse pages in Esperanto.

Vortaro in sidebar with IKUE webpage

In the screenshot, I clicked on the vortaro button on the bookmarks toolbar after visiting the IKUE webpage. Vortaro is the grey side panel and IKUE is the one with the green background.

  • Could you show what it looks like in Firefox? Aug 25, 2012 at 19:17
  • @Oliver I had a png screenshot before, perhaps there were some compatibility issues. I have replaced it with a jpg. The grey panel labeled "Vortaro" (with the red 0 in it) is the sidebar.

  • I just didn't realize that there is a website being displayed in that sidebar. Aug 26, 2012 at 12:22
  • @Oliver it probably wasn't obvious in the original screenshot, I included more of the browser window in this one.

This thread mentions a way to do it by wrapping the bookmark url into a little JavaScript. For instance, to load http://google.com in a sidebar, add a bookmarklet with this as the URL:


Of course, that isn't persistent across tabs, but it's a neat thing to try out nevertheless.

Native support for a sidebar was declined, possibly delegating that to extensions. The functionality enabling extensions to do this hasn't been implemented, and at one point looked like it never would, but a proposal has been under development (preliminary documentation here).

It's been suggested that the dev team is instead focusing on the panels feature (video demo), but it hasn't landed on the browser yet. There's the Panelize extension that promises to allow any page to be loaded in a panel, but as far as I know it only works in ChromeOS.

TL;DR: No, it's not possible yet, but some workarounds may do the job depending on your needs; and support for a proper sidebar (through extensions) is under development.

  • en.lernu.net/cgi-bin/vortaro.pl opens the page in full screen javascript:A14nH=location.href;L3f7=A14nH;R1Gh7="en.lernu.net/cgi-bin/vortaro.pl";if(L3f7&&R1Gh7){Fr4Q='<frameset%20cols=\'*,*\'>\n<frame%20src=\''+L3f7+'\'/>';Fr4Q+='<frame%20src=\''+R1Gh7+'\'/>\n';Fr4Q+='</frameset>';with(document){write(Fr4Q);void(close())}}else{void(null)} does not work.

  • Including the protocol is often helpful. Oops! I added http:// to the url in the javascript. At least it works well enough to play with now.

  • Sounds great, but did not work for me. It will split the window, but then I have to blank pages, instead of google at the left frame. What a pity. It would have been a good solution for me.
