VxTwitter URL Converter di SwedishPotato

Good alternative for this addon: https://addons.mozilla.org/en-GB/firefox/addon/improvements-for-twitter/
tbh I use that extension and this one for discord spoilers (ctrl q)

Mobile version currently has some inconsistencies. Works correctly on desktop at the moment.
Supports twitter.com, x.com, and tweetdeck

Usage:
Share -> Copy Link on a tweet will automatically convert the link to vxtwitter.

Additional Functionality
Ctrl + ` (backtick) will also convert the current clipboard's twitter/x URL to vxtwitter. (Formerly Ctrl + C, changed due to feedback)
Ctrl + Q will do the same but add || to the beginning and end (for Discord spoiler).
