Error code: Out of Memory

[biest1x]

This is because the memory usage of this tab process has reached its limit. First, are you using a 32-bit or 64-bit version of the browser? 64-bit programs generally have a higher process limit. Second, have you tested the situation without browser extensions enabled? This phenomenon is often seen when an extension accidentally blocks some elements within a webpage, but the webpage script keeps trying to create them, ultimately leading to the tab process's memory usage reaching its limit and crashing.

I'm using 64 bit portable version, maybe its portable problem?  And on same sites with same extentions on chrome this error never happened, but thanks for this info i will try to disable them and see if it gonna keep happening.
