Hi, if calling this e10s it is not e10s seems I do not even have that info any more as it is more or less redundant to below. You will have to figure out if to run e10s or not. Default I think is on now.

Please Copy/Paste about:preferences#searchResults into the Address Bar go down to Performance and Un-Tick Prevent accessibility services from accessing your browser. Will need to Reboot as soon as make the change.

Please note : this can cause high use of your cpu cores and of ram. This can cause heat and performance issues so please Monitor in Task Manager. Should stay below 2 gigs. If excessive then do below and monitor and change if need to.

Go the 3 Bar Menu then Options --> General --> Performance and untick everything. change the recommended size lower then see how it runs. Note: 1 = No Multiprocessor = slow again. Try 2 Restart Firefox after making these changes please.

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

after trying the setting, touch behavior still not change (where e10s is enabled)

now i only know to set 'browser.tabs.remote.autostart' to 'false', in about:config, to disable e10s, so that i can use the old touch behavior

is there any other way to let touch dragging to select text or drag a link?

Found it in massive amount of my notes. Need to also set this one, which is browser.tabs.remote.autostart.2 = false

Current Firefox releases no longer use browser.tabs.remote.autostart.2, so if you still have this pref user set (bold) then reset the pref via the right-click context menu to the default value to have the pref removed on the next Firefox start.
