Ugh, if you're gonna pull this shit make sidebar tabs first class! They knew this way before they switched, gave some lip service to make sure the most popular extensions would get the support they needed, and now however many releases later i still have to dig through hidden files and hash-named profile directories to make this work right. And still no usable alternative to tab groups last time I checked, which they took out of core with the reasoning that it should be an extension. At least adblock still works.
