on FFv57 when pressing opening a new tab and there are fewer tabs than the content process limit, it hangs it is short but annoying. Setting the content process limit to 1 fixes it but is Obvioulsy not the Ideal Solution.

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.

Nope. That did absolutely nothing. It was actually enabled already but on or off the problem remains. I am convinced it is the creation of a new thread. And a delay would be fine (understandable) if mouse movement wasn't effected.

What do you mean as a new thread. ? Firefox will not use Multi-thread until ver 58. This is multi-processor which you can try this and reduce the amount that is being used : 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-processor = 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.

I am kinda lost. With threads I meant the thing the tasks manages shows e.g Firefox(6) Hardware acceleration wasn't the issue and setting content process limit to 1 does solve the issue as previously stated. I do not have the option to set it to 0 though, so I don't know If that is the option you are talking about. About firefox gives me 57.0 (64-bit) FYI.

Option is there...take tick out of the box.

but would rather do this : uninstall Firefox. Then Delete the Mozilla Firefox Folders in C:\Program Files and C:\Program Files(x86) Then restart system. Then run Windows Disk Cleanup. Then run it again and click the button that says Cleanup System Files. Note: your Firefox Profile is saved. But you should make a back up before you do : https://support.mozilla.org/en-US/kb/back-and-restore-information-firefox-profiles

Reinstall with Current Release Firefox 57.0 with a Full Version Installer https://www.mozilla.org/firefox/all/
