  • deleteDiscordMessages

    Undiscord - Delete all messages in a Discord channel or DM (Easy and fast) Bulk delete

    Project mention: How to Delete Your Facebook, Twitter, Instagram, and TikTok | | 2022-01-02

    Utilizing bots and scripts is not guaranteed to delete everything either. I've used Undiscord for all of my 10+ accounts. There remain a few dozen messages per account per DM/group chat/server that the script cannot detect due to some weird API reasons, so one has to keep their account to control (delete) that data (your messages).

    Project mention: Any updates coming soon? | | 2022-01-27

    In the meantime, I'd recommend using the github version if possible: The main problem holding it back from release are the build scripts, as they haven't yet been updated for the typescript build.

  • uc.css.js

    A dark indigo CSS theme for Firefox and a large collection of privileged scripts to add new buttons, menus, and behaviors and eliminate nuisances. The theme is similar to other userChrome stylesheets, but it's intended for use with an autoconfig loader like fx-autoconfig, since it uses JavaScript and Firefox's component registrar to implement its more functional features.

    Project mention: Code to open a new tab instead of maximizing/minimizing browser by double-clicking on Tab Bar? | | 2022-01-03

    Oh, you can't use xiaoxiaoflood's autoconfig loader for this. It's for fx-autoconfig, like I said in the first post. You should not be combining the two either, that's a really bad idea. Anyway, xiaoxiaoflood's status-bar.uc.js file does not have -moz-window-dragging in it in the first place. Maybe you have an old version of it. It was updated Nov 22, 2021, so that seems likely. This is why I keep version numbers in all my scripts.
