Firefox used all of my memory and CPU for some time when manually delete entries from browsing history sidebar

Được đăng

Hello,

When I tried to manually delete lot of entries (>2000) from browsing history (sidebar->search->select all->R.click->delete) Firefox used all of my memory and CPU for more than 10 minutes. As a result there where lot of writings to swap file and my PC was freeze until I was able to terminate Firefox.

I tried to reproduce the behavior with smaller set and the same happen on all tries. As an example I selected ~300 pages in history sidebar and delete them. The memory usage (for the process that used the most) went from 250MB to 800MB and CPU usage to 100% for ~2.5 minutes. During this time Firefox was almost unusable and the PC very slow.

All tests, including the initial problem, performed as first task after Firefox complete its load and without any network/web traffic by me.

I don't have the fastest PC or lot of GB of memory, but what I have should be far from enough in order to delete some entries with any additional "re-configuration" on the back, without "melt" it. CPU: Intel Core 2 Duo 2.66GHz MEM: 4GB OS: Windows 7 (64 bit) Firefox: 69.0.3 (64-bit)

Do you think I have to report it a a bug?

Do you think I have to report it a a bug?

Hi irapths,

I think that you don't have to report it. This is a known bug. See for instance:

I don't have a problem with deleting 1000 to 2000 pages at the same time. 500 to about thousand goes fairly quick, but deleting a lot more in one go takes a lot time. I delete such a small set of bookmarks and then continue with the next chunk. In the Library you can easily see how many bookmarks are selected.

Hello cor-el and sorry for the really late reply.

I think my problem is more related to TyDraniu reply about the bug https://bugzilla.mozilla.org/show_bug.cgi?id=734643.

I didn't try to delete bookmarks, but history entries. Maybe the same algorithm is used, but I didn't try this. As I wrote for about 300 pages my PC was unusable for more than 2 minutes. Somewhere, I don't remember where, maybe in one of the bug reports, there is a workaround to this. De-select everything after the press of "delete", but didn't try either since I did my job during my replication tries.

Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.

A small dialog should appear. Click Start In Safe Mode (not Refresh). Is the problem still there?

To reduce the amount of cached memory used in Firefox, go to about:memory and press "Minimize Memory Usage" button. To be honest with you 8GB of RAM is the minimum standard nowadays. Firefox makes sure people with more RAM can utilize them.
