Gartunius I never seen this but I also use zero extensions. So I am suspecting that one of them is causing this. If you start a new clean Orion profile, without any extensions, I assume you will not have any slowdowns. So what you can do to help is try to pinpoint what extension is exactly causing this.

      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?

                  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?

                                JadZeineddine Sorry to add but I just sent the crash report around 1AM central time January 29,2025 and put my email in the crash report incase you want repro or access to my machine (<mylastname>.<myfirstname>@<most popular google email domain>)
