Can't believe using Firefox without this! It's a must-have for Firefox users! Rated 5 out of 5 stars

Can't believe using Firefox without this! It's a must-have for Firefox users which is already perfect only if the author keep developing compatibility versions.

Believe me, I really wanna donate. But donating through PayPal is a bit of trouble for users from China like me due to the hateful internet cencorship. If the author can add some global way to pay, I'll definately donate.

The author said he's not a man with many words, well, I think that's a problem. People won't feel annoyed by the support statement if the extention is truely useful!

Best addon for Firefox !! I realy don`t know what I do without this addon!! I use this addon from first version :D

I realy hate that only Firefox have this addon all other browsers doesn`t have sidebar is realy stupid because for Favorites, Download, History I need to search in options LOL !! With this addon I can open Favorites, Download, History with only one click and History or Favorites will be open, and I can click any page without close it!


For example, in Chrome I need 2 clicks for opening Downloads, Favorites and what is more stupid who need the entire tab for Download, Histrory and Favorites LOL !

With this addon I could have open Download, History, Favorites and I still could searching on sites etc. without closing it! On Chrome you can`t because for Downloads, History, Favorites use entire tab is realy annoying !


This addon works perfect even on Firefox Nightly !!

Please keep up to date :)

The actual reason why I use Firefox, as I couldn't find similar extension for any other browser.

Fabulous add-on, just one question. Is there a way to automatically clear Search when you close the sidebar? In version 0.7.24, a duplicate "close" button was removed from the sidebar header. This icon cleared Search and closed the sidebar. Now there doesn't seem to be a way to do it, at least that I can find.

I've been using this for years. Makes using Firefox much easier. I'm surprised the functionality has not been incorporated into core FireFox.

This is an extremely useful extension, as it makes the interface for browsing history, bookmarks and other internal pages much easier.

Also, the multipanel is a great place to set VLC remote.

Great addon except for the slight conflict with Tab Kit 2nd Edition on the latest version where TK and AIO both seem to be stuck to the same side.
I used to run AIO on the left and TK on the right. That does not appear to be possible any more as switching the setting in TK or AIO switches the location for both.

I've been using AiOS for years and it's probably still the best Firefox usability add-on I've come across. Keep up the good work!

Very great. Because of using an own bookmark server from (http://sitebar.org/) I install it, to see my hundreds bookmarks on the left side in a folding tree window.
