Ok, messing around Activity monitor today and notice it indicates opera helpers using 11GB of memory. Why on earth would this happen. I have 40 pages open, sure, but empirically, I don't see one with more than 10 MB data in the lot. Thanks.
Edit: Opened same pages in Safari and Safari uses 4.9 GB so while the questions remains, obviously I just didn't realize how much memory browsers use to be efficient. I have 32GB total.
Hi @byter86, you can see which tab uses how much memory by using Opera's internal task manager. To do this, click View -> Show Developer Menu in the menu first, and then use Developer -> Task Manager. Perhaps you'll see there's a certain site that makes Opera use a lot of memory.
If you want a workaround to free some memory, restarting the browser will keep your open tabs, but it will only load the 10 most recently used ones immediately.
