Omg, thank you so much for this!
Followed the steps outlined in your post, the only difference in Firefox is that ‘Sources’ is under ‘Debugger’ and it worked perfectly! Thanks so much. No need to faff about with rooted/unrooted Android phones.
Just to clarify, this json file doesn’t seem to have the keyHash mentioned in your post here right? I know I can easily just create a new Bitwarden Vault now but if I can recover my original password that would save me a little bit of hassle.
Either way, again, thanks so much!
