I would consider extending this idea even further:

- Profiles. I have bookmark toolbar with folders of bookmarks for different things such as folder for bank websites; a folder for news websites; a folder from websites I buy stuff from; etc however I also have a folders for websites I use at work. So I would see value in having different profiles: so you click 'Personal' profile and all your personal type bookmarks and bookmark folders are loaded into the browser; then click 'Work' profile and all personal ones are unloaded and any work related bookmarks and bookmark folders are loaded instead. Right now I see work bookmarks in my browser all the time and end up thinking about work when I shouldn't be. You could even have different profiles for different devices.

-History. Having history of visited websites has always been a feature of web browsers but at the same time nobody wants anyone looking through it. How many times have you heard the old dying wish joke of 'please delete my browser history'? If there's a browser extension that manages bookmarks then why not just push through into a full blown Proton Browser extension that stores an encrypted copy of your history that only you have access to.

-Open Tabs. I keep tabs open for some websites, some are pinned to reopen when the browser opens. Some browsers offer an option to share these between devices as well so if this idea were extended into a Proton Browser extension then it would be handy extra feature to have.

-Extension Permissions. I have no idea how feasible it would be but a cool feature would be automatically disabling any browser extensions that haven't been added to a permissions list in the Proton Browser app when you log in to it; +1 for security. Maybe an option to auto-install any required extensions if they're available for the browser? That way you could keep a list of extensions you use and they can be easily set up on new devices.

-Pass or not to Pass? There has been some suggestions to integrate the proposed Proton Bookmarks into Proton Pass which would make sense; but given the additional features I'm suggesting I think it would go beyond the concept of Pass. Maybe instead make Proton Browser and integrate Proton Pass into it instead?

Thanks for reading.

That would be very convenient

Really need this feature for private cross platform bookmark sync

It would also be nice to choose certain folder to sync with specific browsers. I can dream.

Yeah, it is something that would have done my life my much easier.

I'd like to see this added into proton pass. Already do this to a certain extent.

That is an amazing idea.

NEED THIS BADLY! Data organization help is badly needed in this info-overload times we are living in!

I think that this would be a great feature addition for Proton Pass.

That is what I am looking for!
Most of the bookmarks managers on the market give no credible guaranty of encryption, neither give them strong security of users data. So, it would, indeed, be wonderful to have a Proton Bookmark!

I would be interested in this too. I no longer want to create an account with my browser vendor to sync bookmarks. It makes total sense to this be a feature in Pass.

I don't see how it's possible without a Proton browser or a standalone bookmark app.

AI tagging and ability to use natural language queries.

Bookmarks manager similar to Raindrop.io

This, so much this!!!
I've been enjoying xbrowsersync for years now, however, it's no longer working in Chrome. The dev has not updated since 2020 but keeps the project open.
PLEASE, make this happen!

With Pocket shutting down recently and Omnivore a while back, this would be a great time for Proton to enter this market and come up with a bookmarking and read it later app. They have the resources and can easily implement a cross-platform tool to replace Pocket and Omnivore.

Many companies offer bookmark syncing, but without encryption. This exposes a vital security risk (knowing the website addresses frequented by users).

Bookmark management is another component suitable to be added to the Proton family.

I think it's a great idea as a complement to Proton Pass. As part of the implementation details, folders/subfolders seem to be a pre-requisite feature to the implementation of bookmarks, but may I suggest that folders be implemented as part of a more fully-fledged "tags" feature?

Tags are a more flexible organizational tool than folders and can themselves be used as folders if preferred (or used behind the curtains to implement a front-end-only folders system).

I personally think tags are a long-overdue feature that would dramatically improve the quality-of-life of users for many different use cases. If you're seeing this and agree, consider up-voting the feature request (https://protonmail.uservoice.com/forums/953584-proton-pass/suggestions/46872289-tags-to-organize-entries)

As with passwords managers in browsers, it is not the safest option to store bookmarks in them. Kindly add bookmarks to Proton Pass -> browser extensions, if possible.

Currently I am paying for an external bookmark service, would be really cool to have it in Proton.
Have no problem with extra-costs.
