I open mozilla and leave two tabs permanently open for both of my web mail accounts. As time goes on, the memory usage by mozilla graduately climbs up from a starting 14,000 K to well over 65,000 K. Please explain why this is happening. Everything else about the broswer kicks. Reproducible: Always Steps to Reproduce: 1. Open mozilla. 2. Leave it open 3. Memory usage goes up.
It happens for a number of reasons, including but not limited to: 1) Bogus reporting of memory usage by Task Manager 2) Internal caches (eg the memory cache) being filled 3) Leaks 4) The system's memory allocator not knowing how to release memory properly (even if Mozilla has released it to the allocator). Please feel free to file bugs on instances of item #3. Here's how to tell when you're probably seeing a leak: 1) Note the memory usage 2) Load the page you are suspecting of leaking. 3) Reload it a few times ("few" means "at least 5") 4) See whether memory usage increased 5) Close the window 6) See whether memory usage dropped to where it was before step 2 7) Repeat steps 2 -- 6 at least 10 times If you keep seeing the memory usage increasing in step 4 and not dropping all the way to where it was in step 2 on the 9th or 10th time around, chances are you're seeing a leak.
