Thank you both for reaching out.
To confirm, when you say “hanging tabs”, you simply mean that these tabs are slow to load when they are selected/become active? If so, can you please confirm:
Does this only happen when you have many tabs open? If so, can you share how many tabs we’re talking here?
Do you have multiple browser windows open at once?
Do you have any extensions installed in the browser at this time?
It is also worth testing this with the browser open with only one or two tabs and see whether or not you get the same behavior.
@Piroa,
In the profile that keeps freezing, do you have any extensions installed in it? If so, please try disabling them and then test and see if the browser still freezes.
