One of the most valuable extensions available. Rated 5 out of 5 stars

This extension combined with the Google Keep panel extension has been amazing. They allow me to take notes on anything so effortlessly. You can even customize it to slide out when you hover over it, and the slide away when you move away. Highly recommended. Great for students, people doing research, to increase productivity at work, etc.

THANKS Rated 5 out of 5 stars

thanks for this great add on, too bad I just recently found it and wont be able to use it very long. Oh and AjvarXX or whoever you are, grow up and shut up, for the sake of all mankind...

P.S. I thought there was going to be a version of FF supported for like a year that still will allow these addons. And there are other ports of FF. Seems possible for a group to keep alive a version that keeps all our favorite addons compatible. But I couldnt agree with you more quicksaver, seems they were willing to sacrifice so much for what seems so little. Doesnt make sense. And just bc they cant see how usefull ur type of addons are, many of us do!! Thanks again.

Works fine for me in Fx55-56 Rated 5 out of 5 stars

With so many grumpy negative comments directed at the writer of this add-on about the last few weeks of one of my favourite add-ons, I would like write in support of the creator and to note that my installation is still working fine in Fx55-56.

Given that even with Legacy dropouts I've still got close to 100 add-ons, I'm almost surprised that so much is still working fine,

Perhaps those with problems should look elsewhere, rather than throw downgrade the add-on, or abuse the creator.

I also noted the 'new' feature in Fx57 Nightly that seems so familiar, and was noted by another reviewer.

Don't work anymore Rated 1 out of 5 stars

Don't work anymore

Please update it Rated 4 out of 5 stars

stopped working after upgrade to ff 55.0.2 64 bit Rated 4 out of 5 stars

i open it and its empty pane, or cant open/close at all.

i dont expect any feature update i know, but maybe just a quick fix? its still supposed to work until ff 57, right?

is there an alternative? ff vanilla bookmark button is such a retarded thing

FireFox 57 has a built in replacement! Rated 5 out of 5 stars

I dunno if this was intentional, but I just downloaded FF 57 nightly and there is a DIRECT REPLACEMENT for this much loved extension BUILT IN! It looks and works very similar, but is limited in some things. Good enough tho.

One of the best add-on Rated 1 out of 5 stars

But now, its pretty well broken since the lastest Mozzila update, and saddly the autor doesnt want to update it anymore..

So... you can forget :/

ENHANCEMENT Rated 5 out of 5 stars

It would be awesome, if you add Tabs category, where there will be all open tabs and user will be able to search for them.

Gonna be sorely missed! Rated 5 out of 5 stars

Hey, another goodbye and thank you review! This extension, and others by quicksaver, will be sorely missed from Firefox 57 and onwards. But the decision to stop is understandable with the big architectural changes coming. Yet, I very much hope its features will see a continuation after 57 somehow. Anyway, thanks for the great add-on!

Without this and TabMixPlus, i may well ditch Fx :( Rated 5 out of 5 stars

This and TMP have been my staple add-ons since i left Opera for Fx when Opera decided to ditch you know... features. I sincerely hope something like this can be done in Fx 57 because Fx native Bookmark management is unusable IMO (maybe it'll be better in future versions?). I actually donated a trivial amount to this one.

Enjoy the extra time you get. Curious - will YOU keep using Fx?

Thank you for this and your other terrific add-ons.

Best Rated 5 out of 5 stars

Great to have this kind of addon,Thank you & keep it up!

AWESOME Rated 5 out of 5 stars

It's really useful. This addon is the only one reason that it made me change from google chrome to this mozilla. Thanks you.

Thank you so much! Rated 5 out of 5 stars

It's for this reason I only update FF when I can no longer get away w/ the version. I'm a long time user and contributed years ago. W/out a doubt one of the best FF addon out there! Thx 4 all ur hard work and time! Peace.....

Thank you Rated 5 out of 5 stars

Thank you for your great addon. This sidebar was one of the main reasons for me to switch to Firefox from Opera Presto when it's developers decided to turn Opera to another clone of Chrome.

I think you can continue to develop and support your addons on FF forks such as Palemoon or Seamonkey which will continue to support XUL.
