General things that cause Firefox to chew through the CPU, when you
don't expect it to:
1. A large cache, that it's going to process to work out what's old
enough to be discarded.
Not true in my case. I have set the cache size to 0.
2. A long page visit history.
The storage for this list is like a drop in the bucket compared
to the storage for a large web page cache.
3. Keeping the download list of everything you've downloaded.
The storage for that list pales in comparison to a large web page cache.
It is just appended to, so no insertions are made into the middle of
the list as it is not kept sorted.
4. Bookmarked RSS feeds that it's going to visit and fetch updates
from.
I have none of those!
5. Even just a large collection of static page bookmarks seem to
bog it down.
Why would that bog it down? Again, storage for bookmarks
is a drop inthe bucket compared with web page cache.
On my machine, with 0 cache storage, FF sometimes consumes
95% of cpu. Currently running 13.0.1
Those are the ones that I can remember noticing over the years. Point 4
has always seemed a terrible hog, seriously delaying the program from
even starting up, for me. Point 1, tied with point 2, gets seriously
worse over time.
Go through your Firefox preferences, and check out what options are set.
Some of the defaults aren't always the best choices.
