Firefox Quantum Uses an excessive amount of ram for Addons

recently ever since upgrading to Firefox Quantum i have noticed a huge RAM issue and after looming around forums for many months gathering different viewpoints on this problem i feel like the issue is most likely being caused by the new addon handling protocols, once you disable every single addon you will notice firefox uses about 80% less ram, the problem isnt that i have too many addons even with a single addon enabled the RAM usage dramatically increases i personally only use an adblocker and google translator very lightweight addons for any other version of firefox until it hits Quantum, and no i dont use 100 tabs in a single session... i normally use like 2-3 tabs and have only about 8 tabs only max, but if that doesn't convince you at mozilla that Quantum has horrible addon handling take this into your figures Quantum without addons idles on a fresh restart at about 400mb RAM usage but once you enable an addon that number jumps up to about 500-600mb and every addon enabled after that compounds the usage issue

this wasn't a problem with firefox until quantum was introduced, and from what i hear about the firefox quantum the addon handling was changed to disallow addons access to specific browser system files that some addons were using that caused firefox to crash,

feel free to correct me if i'm wrong but “Once you have eliminated the impossible, whatever remains, however improbable, must be the truth.” iv eliminated all the other probable causes and the changes to the addon handling is all that remains

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

On the same web, Edge is using 153.8 MB, Chrome 0255.8, Firefox 565.9. Why & is this going to be fixed?

These results are in Task Manager when all 3 browsers are on on the same page: https://blog.mozilla.org/internetcitizen/2018/08/13/firefox-privacy-philosophy/?utm_source=… (funda kabanzi)

Hi, for the last few weeks, Firefox has been showing ridiculously high disk usage and memory usage - near 100% - growing steadily from the moment I open the program until it stops responding, crashes, screws up my system (mouse cursor hanging etc) and eventually I manage to end process.

Internet Explorer on the same laptop - Windows 8, 8GB of RAM - is fine.

Things I've tried: - Making sure Firefox is up to date. - Turning off Firefox multiprocess - Disabling add-ons - 'Minimize memory usage' in about:memory - Resetting Firefox - Restarting Firefox - The other advice at this page https://support.mozilla.org/en-US/kb/firefox-uses-too-much-memory-ram?redirectlocale=en-US&redirectslug=High+memory+usage

What can people advise?

I was wondering if there way a way to override Firefox's default JS memory limit per tab? Right now, upon reaching about 4-5GB of memory usage, my JS console window reports an our of memory error and dumps my code. I appreciate that this is pretty normal behavior, as 4GB of memory is fairly outlandish for a website. However, for the use case of VR, particularly in physics engine development, it can feel a bit restrictive and even silly when I have 32GB sitting idle - and I could readily double that to 64. However, I know Firefox has a rather extensive about:config section - and I was wondering if anyone knew if one of these variables allowed us to override the internal limits of the browsers memory limitations?
