Several times a day, my Firefox suddenly responds pretty slow and within seconds it no longer responds at all. The CPU usage of firefox.exe goes to 100% and the whole browser seems to be frozen. In some cases, the memory consumption in the TaskManager also increases slowly (about 8KB/s), but not always. However, after 30-60s the problem suddenly vanishes and everything is fine again.
An interesting detail: Firefox uses a lot of memory; I am not sure whether this is normal. Currently, I only have this tab opened, but it still uses 166MB! The peak memory usage even says 351MB, although I did not have more than 8 or 10 tabs open at the same time (no YouTube or similar memory intensive sites).
The problem might be caused by an update to an extension; at least I remember that there was an update shortly before the problem first appeared. However, I do not remember which extension it was. I have disabled almost every extension (only TabMixPlus, Download Statusbar, and TinyMenu are still active), and the problem is still there. It is hard to find the reason because the problem only happens three of four times a day and at random times, so it is hard to reproduce.
1) Anyone has got an idea what might cause these problems?
2) Is there a way to see which extensions have been updated recently?
3) Is there a way to see which extension uses how much of the CPU?
Thanks in advance!
A few times a week
== about two weeks ago (maybe after an add-on update, not sure which)
