Any word on an update to Firefox? Quantum update makes Firefox run really really badly.

Ever since the new update, Firefox has started opening up multiple instances, and I read is for stability and things but even deleting my profile, doing a Firefox or fresh and all these different things. Firefox uses a lot of memory with no Extensions or add-ons or anything installed. It what happened, why is this so bad I have a Windows 10 machine with and I seven processor and eight gigs of RAM, and it's using 400 to 500 MB of my memory. I have scanned my computer with three different software's full scans no viruses, defragmented my hard drive cleared my caches as I said deleted my profile created a new one, have no add-ons installed, did a Firefox refresh and it's still incredibly high memory usage. Anyone else having this? Are they working on an update or something?

A update is not going to help, These days 8gigs is very small. I do not know why Win 10 is allowed to go on...

Update your Video Card Drivers as all websites are using more media or code that uses your card. Old & or corrupted drivers cause issues.

58 will use Multiprocessing like 57/56/55/54/ but will be able to use Multiple Threads .

Go to the Firefox 3 Bar Menu --> Help ? --> Troubleshooting Information Page and take a look in the Accessibility section if accessibility is set to "true" there. if yes, go to the Firefox 3 Bar Menu --> Options --> Privacy & Security panel and under Permissions check the setting to Prevent Accessibility Services from accessing your browser.

You could try this please : Go the Menu then Tools --> Options --> Performance and untick everything. change the recommended size lower then see how it runs. Note: 0 = No Multi-proccesor = slow again. Hardware Acceleration might have also been a issue so turn it off. Run it later and see as you turn things back on and test it, and again. Restart Firefox after making these changes please.

So if are having to do too much of this then there is no point in running 57 as your System can not handle it.

Going back : unfortunately 56.0.2 is no longer safe to use for every day use do to secuity issues, but 52.5.0 ESR is. It will continue to get security updates until May 2018, and you can download and install it from this page: https://www.mozilla.org/en-US/firefox/organizations/all/ Note : Legacy Extensions will be deleted or removed in any version update after May 2018.

You should make a backup of your Profile before going back and just because: https://support.mozilla.org/en-US/kb/back-and-restore-information-firefox-profiles

Please let us know if this solved your issue or if need further assistance.

But my question still stands why before the update was Firefox running well and now after the update which was supposed to make everything better it started to run like pure molasses. And use a lot of memory.
