Firefox: constant freezes for the last 2 months?

Question

Google Chrome

I found that after a certain amount of tabs, the browser starts to freeze periodically for 2-10 seconds, and constantly. Sometimes it starts as early as an hour after the restart.
There are few tabs open (about 10), top-end hardware, the process manager almost always shows 2GB of memory for its process.
I haven't installed any new browser addons.
How can this behavior be cured?

Answer 1

Updated Firefox to 64bit version. She only recently appeared on the main page of downloads, six months ago she was not.
Just in case, I disabled async pan zoom.
In general, now Firefox eats up to 5GB of RAM, but does not freeze. Previously, the friezes were after 2GB.
I think that's the point.

Answer 2

It was in chrome. The AdBlock plugin turned out to be the culprit.

Answer 3

I recently asked a question: Firefox 51 slows down for everyone?
After the reboot, the constant lags seem to have almost disappeared.
But there was such a joke: at some point, at the opening of the next site, the browser freezes. It hangs somehow half: in the task manager it says that it is working, but the CPU load is constant, there is a huge delay on clicks on tabs, but it reacts. One gets the impression that he will now think and droop, but it is deceptive - now he will hang like this indefinitely. Just bang the task and start again.
This happens about 1-2 times a day.
I did not follow clear patterns, but it seems that one of the aggravating circumstances is video.

Answer 4

One reason could be bookmark sync.

Answer 5

Rearrange the browser and check the computer with an antivirus.
Should help.
PS: This is not a problem of plugins, but of stuck events in JS: connections and timers.
Tweaked async, including crash time - much better:

Answer 6

No, it's a feature of FF. It steadily eats away 1.2 gigs of memory for me, though there are not counted bookmarks, much more than 20. AdBlock, NoScript and a bunch of plugins are worth it, but I also didn’t set anything for a long time
