How can I delay Firefox loading windows/tabs from previous session (on startup) until AFTER webextensions have been loaded fully?

In Options: "When Firefox starts" set to "Show your windows and tabs from last time"

When starting Firefox, it loads the webpages before the extensions/webextensions are loaded, so pages are not modified by the extensions/webextensions

This is undesirable in case of ad-blockers, HTTP referer changers, etc. (this is especially noticeable for pre-57 adblock plus extension, but still happens with 57 webextensions)

I'd like a way to delay webpages load until after the browser have finished processing all extensions/webextensions (obviously, at the expense of a slight slowdown on startup), otherwise the page is not modified (which is the reason for the webextension in the first place...) and I have to reload it manually to have it affected

note: those are not my webextensions, so I have no control over them

Do not click on the tabs -- they will be lazily loaded automatically, click them when your WebExtensions have been loaded into memory.

does NOT help for the tab that was selected when firefox closed: on restart, that tab DOES load (before webextensions)

Open a new tab as part of that session, that way when you restore, it'll load on the new tab page.

horrible workaround instead of a solution, now the user has to remember to open a new tab, and of course close it afterwards...

thank you for trying, but acknowledging a lack of viable solution is better

Sorry to have failed you! I'm sure there will be a proper solution soon.
