1598310 - Firefox constantly claiming more and more memory on startup and crashes half the time

Status: RESOLVED INCOMPLETE

(Firefox :: Untriaged, defect)

Description

Attachment: Безымянный.png

User Agent: Mozilla/5.0 (Windows NT 6.3; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/78.0.3904.97 Safari/537.36

Steps to reproduce:

I launch Firefox 70.0.1 on my Windows 8.1 PC. My Firefox is configured to show tabs from previous session.

Actual results:

For around a minute after starting Firefox, the webpage in the tab I was on in the previous session is not shown (contents of the tab are simply white), and Firefox UI is not responding to my clicks. From what I can see in Windows Task Manager, during this period, Firefox slowly eats more and more memory. I'm attaching how it looks like in Task Manager.

Then, two things can happen: either Firefox wakes up, frees the memory, and everything operates as normal; or Firefox eats all of the memory PC has and crashes, with "Bug Report" window.

I was sending multiple crash reports from this e-mail, [e-mail], I don't know whether you got them.

This did not happen on previous version of Firefox.

Expected results:

Firefox should start in adequate time and not crash.

Hi,

I'm marking this as Resolved-Incomplete due to lack of response. If the issue is still reproducible with the latest Firefox version, feel free to reopen the bug with more information.
