Dear [Browser Developer Team],

As a dedicated user of your browser, I am writing to express my strong support for the addition of a second sidebar. This feature would greatly improve my overall browsing experience and provide me with more flexibility and convenience.

Having the ability to open multiple sources of information simultaneously in a second sidebar would allow me to easily compare data, reference material, and switch between tasks with ease. This would save me time and increase my productivity, as I would no longer have to constantly switch between tabs.

Furthermore, the addition of a second sidebar would also benefit the add-ons I use on a daily basis. With the ability to utilize the second sidebar, add-ons would be able to provide me with even more tools and resources, such as translation tools, news feeds, and social media widgets, in a convenient and streamlined manner.

I believe that the addition of a second sidebar would be a valuable addition to your browser and would greatly enhance the user experience. I urge you to consider implementing this feature in future updates.

Thank you for your time and consideration.

This is the big feature that keeps me on Vivaldi instead of Firefox.

I don't even think it needs to be a second sidebar - just a way to easily (with GUI) have multiple sidebar applications, like how Vivaldi/opera do it. though a second sidebar would be nice too. I'd put my calendar on there in a heartbeat

I totally second this. In fact, I suggest generalizing this into "multiple sidebars", where the user can simply click an "Add new sidebar" button to create a new one, then put whatever they want in it.

Surprisingly, Edge's new sidebar isn't terrible! You've got AI chat which saves having to open a new tab and open a bunch of search results (which also means you can't see the original tab - you have to switch back and forth). You also get Insights about the current site, like rating, traffic stats, etc. Hopefully pics come out OK, uploading to this site was hit and miss

Vivaldi's sidebar is the only thing keeping me over there. At least a way to have pinned apps such as that (or similar to wavebox) would be great here.

The sidebar for Firefox will be an excellent addtion to improve productivity. On the day-to-day basis this kind of simple solutions improve a lot the use of the browser by allowing to have multiples websites running at the same screen (for example: web meetings, web calendar, spotify, money exchange, bitcoins monitoring, etc).

Best regards for all!

@KERR  Yeah, several browsers have adopted the "sidebar with many functions" design pattern, and it's really great. Edge, Opera, Vivaldi, just to name a few. I think it's about time Firefox adopts the same pattern.

I think the requests for this feature hint at a deeper need for more ways to interact with certain websites.

Pinned tabs are handy, but already there are browsers (e.g. Vivaldi and Opera) experimenting with novel and interesting ways to interact with the browser and websites. I mean, have you seen those sidebars? Opening WhatsApp, Telegram, a Thesaurus and sometimes even Wikipedia just to the left of the tab I'm currently seeing was so, so useful and just... nice.

It was genuinely one of the hardest things to drop when I migrated to Firefox. No offense to the developers, I really respect all the work you do :^) but I'm here in no small part due to ideological reasons.

I don't really want or need a second sidebar, but I would greatly appreciate a better one.

Just a stray thought I had scrolling through the ideas.

Floorp (based on Firefox) does this.

Activated account to comment on this. I would love a second sidebar. I personally use Bitwarden password manager which supports sidebar, but I also prefer to always have history open on Sidebar for quickly getting references for research. I would love to be able to see both of these utilities at the same time. Have plenty of screen real estate these days so no issue there. 

Thank You,

Adam Sowder

okay this would be pretty cool

Simply chiming in to second this idea. I have only recently made the full switch to firefox, especially due to it's customizability userchrome.css and extensions like sidebery & firefox color provide. A second sidebar would open this up so much more.

I really liked the second bar in Edge allowing you to keep some websites there in mobile format, especially useful for chatapps, mail, notes, To-Do lists or as more primitive tiled splitscreen. Having that simultaneously as another sidebar using sidebery for vertical tabs would complete my firefox experience, both for daily usage and research.

While I don't believe in chasing every trend, recent trends in the browser market to me clearly show demand for these features

We really do need the ability to open a second sidebar specifically open one on the right and the left simultaneously.

Lets make this idea as a trending topic! Please share it and/or comment it.. the most attention to this post we will make it a reality! This is a big game changer for Firefox! Users will appreciate this a lot.

Thanks and regards to everyone. @JRGN

With the addition of chatbot shortcuts to Nightly (, a second sidebar is now borderline mandatory to make the feature even useful for people using vertical tabs.
