Someone else's character linked to my account

So, when I joined my current game, I joined at the same time as another player. We both set up accounts and characters at the same time. Thing is, her character got linked to me (and potentially everyone else in the game). Whenever I play, in the drop down to select whether I'm talking IC or OOC, her name is listed as well. I can't figure out how to clear her from my account/character association. From my understanding, it is a one-way link, and my details are not showing up on her end. Any help to fully clear this would be appreciated. Thank you! Edit: I am on Firefox version 82.0.2 (64-bit) for Windows 10, I do not know what she was using.

Hi there! GM from the game will have to do it. Her character sheet is probably set to "Controlled By: ALL PLAYERS". Whereas your character sheet is set to "Controlled By: Alimorel". That's why your name isn't showing up in her IC/OOC speaking as drop-down menu. Sometimes GM's do that before they even know the new player's name or login, we just toss a few "All Player" accessible sheets, so that someone can claim a sheet when they log in. Your GM needs to press EDIT on her character, and change the Controlled By / Edit Permissions, to her Roll20 username alone.  There's really no harm in it, if everyone is friendly and kind. Just don't go edit her character sheet, and only use your own character name(s) from Speaking As... drop-down. This is very likely NOT a glitch, nothing to do with joined same-time, nor Firefox, Windows, and so on.  It's a choice, on a setting, configured by a GM. Happy gaming! Cool Avatar you have on here.
