how to use xkit rewritten / trim reblogs on mobile:
updated for december 2022
this method is beta editor / npf compatible
my previous tutorial to trim posts technically still works, but as tumblr is discontinuing legacy posts that method is already outdated and unhelpful for people who have no other option than to use the beta editor.
but fear not! i've figured out how to use xkit rewritten on mobile and it's VERY easy.
install "firefox nightly for developers" OR "firefox beta for testers". must be one of these two, not regular firefox.
go to settings, scroll down to the "about firefox" page at the end and then click on the logo 5 times until debug mode is enabled.
back to settings and below add-ons you'll see the 'custom add-ons collections' option.
add 17683742 as the ID and name it 'tumblr' like so:
the browser will give you a little pop up that the extension is being added and the app is being restarted.
now enter the app again, go to the add-ons section and xkit rewritten should be loaded there. i've included ublock in the collection so you can use both because you absolutely should.
on firefox beta you'll see the extension with a +, click on it to add it.
now cut your replies the same way you do it on desktop with xkit rewritten!
save the post as a draft
click on the scissor button
it's done!
please consider that this is experimental so not all of xkit rewritten's features will work on mobile. trim reblogs does work though!
i still recommend using my roleplay formatter for formatting your replies and then copy pasting the html on your reblog.
