Dear Mozilla developers,
please take into consideration adding “delayed tab loading” (TM) to Firefox.
It would be the best feature that firefox could have since the introduction of tabs.
This same functionality is provided by the extension BarTab [1] (https://addons.mozilla.org/en-US/firefox/addons/versions/67651) but this should be done by Firefox itself.
“Delayed Tab Loading” (TM) has an enormous impact on Firefox’s performance and usability.
Loading Firefox with several, even little as only ten (10), will severely impact on Firefox performance. Not only the browser will become slow and unresponsive, but so will the system as the Firefox tries to load every tab at the same time, slowing everything down. This can take several minutes where the user can’t even use the few, already loaded, tabs.
With “Delayed Tab Loading” (TM), like BarTab, only the active tab will be loaded by default, all others will be loaded *on demand*. The reduces greatly the time taken by Firefox to start and be operational, both increasing performance and usability.
The startup time improvements that you are pursuing will be nothing compare to this.
[1] BarTab stop working with the late nightlies (therefore the reason for my request but that has since been corrected) and still doesn’t officially support nightlies.
Thank You.
