With 4 tabs open, 1 being the one I am using to type this message on, 1 being in youtube's homepage and 1 youtube video consume 750Mb of ram...

Also the browser is generally slow when loading pages and it doesn't feel smooth when it loads. It kind of stutters and does that when scrolling through the webpage too. I want to switch from chrome to firefox but this is making it a very difficult transition.

I even have a quite powerful machine in my opinion and I also have hardware acceleration turned on. Here's my PC specs: xeon 1241v3 - 8gb RAM - gtx 1060 OC 6gb - 500 GB SSD I'd like to add that this is a fresh new installation of firefox 64bit. I have only 1 add-on which is adguard and I tried to disable it to see if it could be the problem to my stutters but it wasn't. I updated flash plugin to latest (which I found, I believe it's version 26). I am out of ideas.

Ok, Please update your video card drivers or re-install them https://support.mozilla.org/en-US/kb/upgrade-graphics-drivers-use-hardware-acceleration Please try with No Hardware Acceleration also.

Please try this as have only 8gig of ram. This will increase your swap file size. MICROSOFT VIRTUAL MEMORY

You may want to try this: Open the System Folder then Click on left side Advanced System Settings which opens System Properties click the Advanced Tab then click Performance button Settings then the Advanced Tab then Click the Change under Virtual Memory click Custom Size and Change Size to where it says Recommended Size then Click Set and then Click Apply then please Re-boot.

System - -> Advanced System Settings --> System Properties - -> Advanced Tab - -> Change Virtual Memory - -> Custom Size - -> ENTER Recommended Size - -> Set - -> Apply-- > Reboot

You can download the full installer here, find your language (is on 64x) https://ftp.mozilla.org/pub/firefox/releases/54.0.1/win64/ Instead of doing a refresh below.

If above is no help and that this is a new install of Firefox there may have got a corrupted file while installing from the Stub Installer. So please try this : https://support.mozilla.org/en-US/kb/refresh-firefox-reset-add-ons-and-settings

Since is a new install and you have not hopefully customized to heavily going nuclear on you to start might be the best thing to start with.

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

When multi-process windows in Firefox is enabled then Firefox will use more memory and may be less responsive. Try to disable multi-process windows in Firefox to see if that has effect.

You can disable multi-process windows in Firefox by setting these prefs to false on the about:config page.

  • browser.tabs.remote.autostart = false
  • browser.tabs.remote.autostart.2 = false

You can open the about:config page: via the location/address bar. You can accept the warning and click "I'll be careful" to continue.

I have checked my gpu's drivers and they are up to date. I have gone to check the recommended the required amount and it's set at 1.9 GB. I did not really change anything, I just let it to automatic settings. As for the refresh, it didn't fix it by much at all. I still have the same problem of the browser being slow.

When I went to about:config, browser.tabs.remote.autostart was already set to false and there is no browser.tabs.remote.autostart.2 option when I type it in the navigation bar.

Never mind I found browser.tabs.remote.autostart.2 and it was set to true. I set it to false but now with 6 tabs it consumes 1 010~ MB of ram when it used to consume around 950~ MB of ram.

I recently uninstalled firefox and re-installed it again but I still have the same problem. When opening multiple tabs it stutters a lot and it still consumes a lot of RAM after turning the settings to false for browser.tabs. Why is it doing this to me. Or is the browser it self supposed to be like that?

Should I just try and use the 32bit version?

Do you see any reported errors during this behavior in Tools > Web Developer > Browser Console with just the Logging tab fully enabled?

I do, but I don't know which matters.

Of course. Do you see anything like "Could not write session state file"?

If not: - What happens when you create a new profile, launch that profile without installing any add-ons, and open the same websites? - What happens if you unselect Enable Adobe Flash protected mode (if selected)? - What happens if you uninstall Flash entirely?

No, I do not get any errors that you have mentioned. Here's the errors I get (assuming the highlited stuff in red is an error): I get telemetrystopwatch errors, error for retrieving geoip data, downloadable font: kern: too large... and I get a huge amount of errors from adguard-adblocker with stuff like typerror: tab is undefined, typeError window is null: typeError: addoninfo is undefined, etc. Even with Flash uninstalled, the browser still behaves the same way. Consuming a lot of RAM, CPU and is still sluggish. I have also removed AdGuard but same.

Did you create a new profile and launch it? Please understand that’s important in order to know what a fresh profile does. A Firefox Refresh is kind of similar, but copies some old files that may still affect performance.
