I have to use #Outlook for work. I use multiple (#Linux) machines and don't want to manage offline copies of messages on them all. So #browser access is preferred over Thunderbird or similar.
Composing emails in Outlook on #Firefox or #Waterfox is a nightmare. #Bold and #italic can only be toggled following a space (leaving a bold/italic space - shudder). When pasting links, any preceding space is removed, concatenating the link with the previous word. Following the link, increasingly complex sequences of escape (to dismiss the context menu) and either punctuation or [newline, space, left, backspace, right] are required before I can type another character. Etc. It's almost the same with Mullvad (it doesn't delete the space before a link).
I just found none of this happens with #Chrome. #Vivaldi also seems to work fine.
Given all this, I'm reluctantly going to use a non Firefox browser for my work persona.
What is the current recommendation for a reasonably privacy-oriented browser that isn't based on Firefox / Gecko?
