@hub Edge still fully supports v2 AFAIK, no sketchy workarounds needed. My employer [redacted] banned Firefox a while back to "cut back on support load" and Edge is the only allowed one that can run the full version of UBO. (They also implied Mozilla doesn't update it frequently enough, but that's complete BS in my experience with how often it asks for a restart to update vs chrome...)

Though I'm not sure how hard of a fork it really is, so if upstream chrome starts rearranging the internals they may be forced to drop it as they pull improvements and bugfixes in... (If they're forced to drop it, I'll be sending some emails to our browser security team given how much malware is distributed via ads these days. The only reason I didn't complain about the firefox ban is that edge can still run UBO...)

EDIT: to be clear, I wouldn't recommend it in any way if Firefox is an option. Just pointing out that in certain situations it may be the "least bad" option when Firefox isn't allowed.
