Actual behavior

While browsing, all page changes take 8-10 seconds to begin responding while Firefox Task Manager reads sustained "high energy utilization" for the account containers extension

Expected behavior

Normal page changes in <1sec as I immediately get when disabling the extension

Steps to reproduce

Open a web page
Read it (problem doesn't seem to resurface until firefox has been running a few minutes - first few loads are always quick)
Click a link
Tab shows the loading animation for 8-10 seconds before navigating

Notes

Similar to #1924 except for me it does not require sleep/wake after launching firefox
I originally had container preferences sync'd with firefox sync, but have been able to reproduce the problem since turning that off
Disabling and re-enabling the extension (without removing it) deletes all my custom containers and rules, not sure if this is a symptom or just a terrible design decision

Downgraded to 7.1.0, but problem still persists. Happens across OS's as well - seeing same behavior on WinPro64 as well as BigSur - all FireFox v85.0 64-bit

I have noticed this happen when I leave the browser on and unattended for over an hour. If I disable the extension and then reenable it, the problem goes away temporarily. I don't have the same issue as the OP with it removing my containers, however.

DarthHeizenberg commented 3 years ago

@flanger001 - similar observation here as well. Downgrading to 7.1.0 and restarting the browser makes it all fast again and then load times get longer and longer. Doesn't always take an hour though - I've seen slowness kick back in within 15 minutes on MacOS a few times now.

flanger001 commented 3 years ago

Update: I don't know if there has been a recent push on this but I am no longer experiencing these delays. I'm on FF 85.0.2 now.

Just kidding it's back.

I have been experiencing similar problems running Nightly on Debian Buster. After every browser restart, pages take 15+ seconds to load and my CPU usage shoots up; disabling/reenabling the extension usually fixes the problem until the next restart, though sometimes I have to try it several times before it works. Has anyone taken a look at this? It is obviously very annoying since Nightly needs to be restarted often to install updates.

Update: it appears my problem was likely related to https://github.com/stoically/temporary-containers/issues/371. Turning off sync and deleting the accumulated temporary containers seems to have improved performance.

I started experiencing this issue last week across all my machines. Kept disabling add-ons one-by-one until I realized MAC is the culprit. I have two issues - 1) there's a delay in the loading of pages when this add-on is enabled, and 2) after a while Firefox just stops loading anything. I don't have to sleep the computer or anything... it just stops working after a while. Disabling the add-on fixes it.

I keep hoping for a fix but on Firefox 95 and the latest plugin update it still starts hanging after sitting unused for a while. This extension is the primary reason for me to use Firefox. Until this is fixed I will be using multiple profiles in a chromium based browser.

I have the same issue. I even set up a new firefox profile, without solving the issue. After opening a new tab, loading the page just takes forever. I can open, in parallel, the same page in a different context and it will load immediately.

I think this issue is reported multiple times already:

mozilla / multi-account-containers
