Looks like you did not actually go to about:addons in your Firefox browser as suggested, but instead went to Settings > About in your Bitwarden browser extension. Seems like @Nail1684 already clarified this for you.
Neither this thread nor the UI feedback thread have any notice about automatic closing of the thread. Such notices normally appear when a post in the Ask the Community section is marked as “
Solved” by the OP.
I don’t know why you have comments that have been deleted. It could be a technical glitch in the forum platform, or it could be that a forum admin has removed one or more comments that were deemed to violate the Community Guidelines on respectful and constructive communication.
For the record, like @Nail1684, I am just a Bitwarden user/customer like you, and I am not employed or otherwise paid by Bitwarden. I do volunteer as a community moderator on the forum, but my powers are very limited and do not include the ability to remove comments. I also don’t have access to any forum administration logs that might show when/why comments were removed.
One thing I am able to do is to close and re-open threads, so if there is ever a thread that you feel has been closed prematurely, please DM me and I can see about re-opening the thread for further comments.
