I have seen many posts in the past complaining about browser memory usage. So, the idea of this thread is to compare each user browser about:memory page, to see where the memory is going and perhaps try to optimize it. Additionally, some users might not be aware of the existence of the about:memory page. I think this can be fun, educational and helpful at the same time.
I am not an expert on memory usage, but I think that together we can figure out some things. For instance, as you can see under the storage section in the screenshot below, that lazarus.sqlite database is using 60Mb.
Lazarus is an extension that saves what you type in forms, so in case the browser crashes you can recover the text. It is a very useful add-on, however 60Mb is too much to trade. So I opened Lazarus Database preferences and used the feature to Clean The Database, then restarted the browser. I didn't help. So I opened my FF profile and deleted the lazarus.sqlite. I probably could have done through Lazarus preferences as well. Anyways, I have gained 60 Mb in my Firefox RAM usage.
This is a temporary solution tho. I have reduced the time lazarus keep old forms and will see if the database grows too much. If it does, I might go back to Textarea Cache extension.
So, let's see where your browser memory is going. If you have many tabs open, keep in mind that some page addresses might be revealed in the about:memory page. So, check the about:memory page before taking the screenshot.
How to get the memory page?
Simply type about:memory in the address bar and hit enter. It works for Chrome and Firefox. However, it doesn't work on Firefox 3.6.x, only in Firefox 4 upwards.
How to make a screenshot?
I recommend Awesome Screenshot, which is available for Chrome and Firefox:
