Hello, I recently moved to Firefox from another browser and I am very pleased with it. My usage is that my computer remains on 24/7 with the browser open. I saw a paragraph in the help docs:

"Firefox's memory usage may increase if it's left open for long periods of time. A workaround for this is to periodically restart Firefox."

However this can be inconvenient when you have several tabs open that are logged in to various sites for work, which also retain state which is not restored when the browser is restarted.

Over a few days the memory "leaking" (?) is mounting up significantly as per attached. In summary:

Pre close - system RAM usage 12.5GB Post close browser - system RAM usage 8.1GB (4.4GB drop!!) Re-open browser with same tabs - system RAM usage 8.7GB (actually 9.0GB after all tab views were accessed and put back into the state they were in before closed)

From this simple test I can see that 12.5GB - 9GB = 3.5GB was hogged by the browser and not actually required.

As a developer I am interested to understand the reason for this memory leaking. Is there anything I can do while the browser is open to free it up? Or cause it to not "leak" in the first place?

Thanks,

Andrew
