After 1-2 days, Orion becomes very sluggish

mattheja Would it be possible that you pinpoint only one offender or otherwise have minimum steps to reproduce? Or anything that is actionable for the team.

Steps to reproduce:
Keep a lot of tabs >60 opened for more then a day. I didn't try with compatibility mode because it's not a problem with a website, also from my understanding of what compatibility mode does, I would not like to open all my stuff for a couple of days without the protections.

Expected behavior:
Normal responsive usage, resizing and changin tabs without a small delay.

Problem
When changing tabs, or resizing the browser, and doind some other things like trying to hide the vertical tabs space when changin to a tab, the browser becomes unresponsive, taking a couple of seconds to actually do the action(in this example it would be around 2/3 seconds before the tab gets loaded).

After a restart the browser returns to normal.

Orion, OS version; hardware type:
Orion Version 0.99.123.3-beta (WebKit 615.1.16.1)
MacOs 13.2.1 (22D68)
Apple M1 PRO

Gartunius Can you show a video of this behavior? Can you try Develop -> Empty cache when this happens next time? Can you try to reproduce this wtith zero isntalled extensions?

In principle, I have over 100 tabs open at all times and I do not experience these. I also do not run any extensions so wondering if extensions you have installed are the culprit. The more information you cna provide th efind the root of this the better.

Sorry for the very long delay(work + testing your suggestions), but here are a couple of screen recordings, the first one is showing the responsiveness problem when opened for too long, also I you can see I'm using Ublock there, but I've tried removing each extensions that I was using and no combination would solve(or improve) the problem:

But I ended up with the same problem regardless of the combination, eventually I just went back to Ublock

*Showing the responsiveness problem:
Obs1: I made sure to record the mouse clicks, so you can see when I double click the topbar of orion to get it to fill the screen
Obs2: The screen capture is not lagging

And here's when I reseted Orion, just completely closing it and opening again:

Here I also make sure to record the mouse clicks, so you can see when I do the double click to full screen.

Also maybe it's worth bring up that in general my whole system has gotten more slow with Orion(I don't mean with the app installed, but as Orion gets less responsive, other apps get less responsive too) I'm trying to troubleshoot my system, but what makes me think that "it's Orions fault" is that when I close it things go back to beeing responsive.

I also keept the Activity Monitor open to see if there was a huge usage of CPU and/or RAM, but there wasn't, it was normal, CPU bellow 30%, and RAM around 12/13GB.

I'll post here any updates on troubleshooting.

Vlad Ok, I created a new profile withouth extensions, I'm going to use it for a couple of days to see if the problem shows up again, if not I'll start adding extension by extension to see if one of them causes the problem to show up again ️

Sounds like a plan.

Update on the performance issue, for the 3/4 days that I used the new profile withouth extensions things worked well, but scince I installed Bitwarden from firefox the performance after a couple of days dropped again, and now whenever I move Orion between screens I see the same lag as I showed in the screen recording before. Is there anything I can do to help debug the issue?

Gartunius So it seems to be caused by the Bitwarden extension and somehow "bad stuff" accumulates over days of usage. @dino any ideas what to do to further debug the cause?

I know that there's a version of the extension for safari, but I couldn't find a way to install it to test, is that possible? if so how can I do that?

Gartunius Not possible to install Safari extensions.

Just a "final" feedback, after I turned on "Low power mode" which from my understanding unloads the tabs from RAM, the issue hasn't happend anymore, even other apps wich seemed to lag stoped having problems, so my suggestion would be something like the extension TabWrangler that auto closes some tabs after a while, something like the ArcBrowser does(I only heard, didn't test it myself), personally I think that would be a better experience overall, still having the instant switch but with more controll over which tabs stay open/loaded into RAM.

Considering the issue only occurred with extensions and disappeared with low power mode, I wonder if there’s some background processes that extensions are allowed to run when tabs normally aren’t. When low power mode is off, there appears to be limits for tabs but extensions run unchecked.

I noted in your screenshot you have Ublock Origin extension installed. Any chance you have forgotten to disable Orion's baked in content blocker globally as is necessary to prevent them interfering with one another?

Ulmamater Yes at the time I didn't disable Orion's content blocker, but I did use it for a while withouth any extensions and the problem continued.

Any updates on this? @Gartunius

I have experience the same thing - fresh instal of MacOS 15.2, roughly 60 tabs open, 2 extensions, Orion crashed. I believe the reason is because of the extensions, however these are fairly popular extensions vimium (lightweight) and startpage (lightweight) but that doesn't mean they dont have a memory leak. However I cannot confirm that.

Can someone look at the crash report to verify this issue? It feels like if you want to use Orion Browser you shouldn't use any extensions, is that fair to say?
