Title:
System memory thrashes when Firefox accesses certain websites
Status in “firefox” package in Ubuntu:
Confirmed
Bug description:
See Question #198533 for details on problem reproduction and some memory
statistics. Recent Ubuntu updates have made the situation slightly better:
* the Firefox window only occasionally grays out if at all and
* mouse control is retained although movement is still jerky about 75% of the
time.
Now I can end the Firefox process (through System Monitor) without rebooting
most of the time.
Testing has shown that running Firefox without extensions, plugins,
and JavaScript and in safe mode does not bypass the problem. Running
with the RAMBack addon or a new profile also does not help. The
about:memory page cannot be accessed after thrashing starts. System
Monitor shows Firefox using less than 250MiB and the ten next largest
memory users using only about 30MiB total on a 512MiB system.
