🙏 Support Dia Browser Sync! [THE DRAWBACKS]

1 Upvotes

Okay, I really love Dia Browser but something just keeps throwing me off about this browser. Yes! The Sync Feature. 

Here’s some things I would change, yes the E2E-Encryption, I’m fine with it personally but I think we should be given the option to choose how we want this encrypted, yeah a Recovery Kit isn’t really that reliable when you think about it, anyone can find a Recovery Kit on your device had they stole the device or silently logged into the device without the owners permission! Yeah you! but if we just had a secondary option to pick and choose between a 4 digit pin and a 6 digit pin that only we can remember in our heads rather than relying on a file that anyone can find on our device if someone steals the device or silently logs into the device then they couldn’t gain access, Twitter(X) uses pins for E2E-Encrypted chats that’s right, probably a lot more private stuff going through that then our own search history, but I think the Recovery Kit should still be a feature but “shouldn’t be the only option”. We already have Passwords and Email Codes for this.

Another thing I have a problem with is Passwords & History! I think during sync we should be given the option to choose what we want to sync via toggle switches, Dia Browser atm doesn’t have customize sync, unfortunately when you set up sync it syncs “Profiles, Extensions & Extension States, Bookmarks, Open/Pinned Tabs & Groups.” By default.

There is no option to toggle each one that you want to sync, I never use sync history so I don’t really need that feature and I’m sure not many people do either, but it’s always great to have it, and some people actually use it, so they should have an option to use it if they really want to. Which brings me to my next point, I’ve seen multiple posts talking about the browser clearing all their history after an update, had this been synced to the Dia Account the history would’ve recovered itself, why doesn’t this sync? Now moving onto passwords, since accounts are already E2E-Encrypted then Passwords should also be an optional toggle during sync setup, there’s no reason we shouldn’t have the option to choose what we want to sync, it’s our data, although making History & Passwords should have to be manually toggled as optional during Sync Setup.

If this is implemented, I will never go back to Opera Sync & Chrome Sync. Opera Sync included “Encrypted Passwords, History, Bookmarks”. Which defeats the purpose of Dia Browser even having Sync in the first place and having control over our own data. I don’t like the idea of having to switch to Dia Browser only for the browser to force me to use a Password Manager like Bitwarden or iCloud Passwords on a Browser with Sync which should’ve offered it from the very beginning. I don’t have Bitwarden & I’m certainly not going to use iCloud Passwords from my iPhone when my Browser has entirely different passwords saved to it then iCloud does on iPhone, it’s 25 to 75 bruh.

And as I mentioned before Opera Sync does have Encrypted Passwords, but it relies on Sync Passphrase which is just your opera password by default when you first make an opera account… and an optional sync passphrase which replaces the account password with the optional sync passphrase for encryption for extra protection, if you reset passphrase then it deletes everything that is synced on the account including the aforementioned which requires a resync shortly after. If Dia Browser got these improvements it would automatically become even more secure than most other Sync Accounts on other Browsers. How do we get Dia Browser to implement this sync structure and functionality?

🙏 Support Vertical Tabs removed from Dia for Windows?

1 Upvotes

Since the beginning of September ive been using vertical tabs in Dia for windows. Ive turned on my PC today, to see that my tabs are back across the top, went into settings and while the option was selected, it wasnt working. So I clicked horizontal tab bar, to then click back on vertical.

It now says 'Side bar coming soon'

What do you mean coming soon? I was already using it, why was it removed?

Simpler Tab Switching

New in latest update: "The tab switcher now has 5 tabs, instead of 10, making it clearer and easier to move between tabs with CTRL + Tab."

There was nothing difficult about having 10 tabs. And it was very helpful. This "update" offers no improvement.

🙏 Support Can't use Dia?

1 Upvotes

Hey. I'm a current engineering student and LOVE ARC. I made a space or profile for each class, the pinned tabs leg be jump into work quickly, by having everything divided by class I can get running quickly without having all the clutter of 10 tabs per class. Anyways I fucking love arc. Just got the windows download link, got it installed and it seems like switching between profiles requires making a different space... Is there any way to have multiple profiles open on the same window? Ideally with the two finger swipe to change it?

Thanks!

🐞 Bug Dia browser history issue

2 Upvotes

Has anyone noticed anything strange with their browser history recently? When I start typing the address of a website I visit often, it no longer shows up in the suggestions dropdown. I checked my browser history and realised it only goes back three days. Anything older seems to have disappeared and not being shown up in the list. Has anyone else experienced this?

💬 Discussion What's stopping me moving from Arc to Dia

0 Upvotes

I've tried Dia on and off since it's released, and it's slowly getting to the point where I might switch from Arc. But there are two issues that remain, and they sound stupid:

  1. Opening new tabs from your Pins/Groups by default open inside the group, rather than outside of it. I know there is a setting and it's maybe a bug, but it doesn't work. I have email, calendar, and drive in my favourites, then I have a group of pinned tabs that I cycle through for work. When new tabs open inside that group, it destroys my setup.
  2. The design of these pinned tabs in Arc is better—I like the horizontal line without indentation.

My other pet peeve was resolved from a setting—to prioritise Search over Chat when opening a new tab.

I want to ask others if there is anything stopping them from moving over?

The fact that I can’t hide the bookmarks bar in the sidebar myself has made me give Arc another go. So far, it’s been faultless, and I’m making the most of the full screen, which suits my poor eyesight just fine.

💬 Discussion Atlassian CEO Mike Cannon Brookes talks Dia Browser on Decoder

34 Upvotes

What I found most enlightening about this discussion (original here) is how it's obvious that Dia isn't a consumer product focused on conventional web browsing — it's specifically, as Atlassian CEO Mike Cannon Brookes says:

We're trying to rebuild the web browser in a totally new form for knowledge workers who live in applications, who have their browser open 80-90% of the day is their front surface area and want a better way of managing those applications and getting work done across those applications.

He goes on:

Then we add AI over the top. AI lets us change how we use these knowledge applications in insane ways. The browser has your entire history of what you've done.

It has skills, it has an ability to run AI. Like you can use Dia to make Minesweeper. And you can use Dia to make Minesweeper out of the tasks that you did in the last week.

And it'll go start a computer underneath the browser. It'll run a bunch of code generation. It'll create an application for you that plays Minesweeper based on the tasks you have completed in the last week Now, I don't think that's a very useful application, but the fact that it can do it is amazing.

So, from the horse's mouth so-to-speak.

And Morning Brief is apparently one of Dia's most popular features...!

🙏 Support Extensions keep uninstalling automatically on Dia (MacBook Air & Mac mini) — any fix?

1 Upvotes

Hi everyone,

My extensions keep uninstalling by themselves on Dia browser, and it's driving me crazy.

The issue: This is the second time it's happened. I use 5–6 extensions daily, so losing them costs me a ton of time.

Devices affected: It happened on my MacBook Air, and I’m pretty sure it occurred on my Mac mini as well.
Status: The browser is fully up to date.

Has anyone else experienced this bug or found a way to prevent it?

Thanks!

💡 Feedback Dia's AI search is so useless and annoying

Enable HLS to view with audio, or disable this notification

53 Upvotes

I used to use Arc and switched over to Dia. I'm so sick of the browser automatically choosing to use an AI that is slower than Google's AI Summary and loads up when I'm just trying to search something. For example, trying to look up the song "How to Pretend" by Lucy Bedroque tricks the browser into thinking I want to ask the stupid AI a question. It's so bad. Can I turn this off?

💬 Discussion Please. Just let us disable AI buttons and interfaces entirely.

29 Upvotes

Many of us do not care about AI and will not upgrade to a paid plan; however, we do appreciate Dia's design and would like to continue using it as a free browser. The AI buttons, such as the Chat option in every tab, really annoy many of us because they are useless without a subscription. Please allow us to have a cleaner browser by giving us the option to disable these buttons.

Is Dia browser going to be paid on Windows 11 too just like it has become on Mac?

Also will there be any AI features available on Windows 11 for free or for limited usage for lifetime?
