I've been running into more and more bugs with Zen, often around tab management.

• The other day I tried moving some tabs between windows and the tabs just disappeared. They were still accessible with CTRL+tab but otherwise hidden.
• It seems to make new tabs randomly when closing other tabs.
• The workspaces are confusing and linked to individual browser windows. If you move out of a workspace, you can't get it back unless you open it in the same window you left it from.

Might switch back to Firefox and wait for more development, or Firefox's native vertical tabs.

Cool experiment nonetheless

Been using LibreWolf for a few months and before that just regular Firefox with the ArkenFox user.js.

Basically the exact same experience just with the peace of mind I won't end up with some weird Ai crap after an update.

Everyone always whines about anything Mozilla does with Firefox. These additions are at least much less intrusive than their addition of Pocket.

Zen is really good but I've found it likes to crash my Gnome session when it's open at the same time as regular Firefox. It also likes to crash my Gnome session at random. Other than that I really like it, I'll try it again soon
