I certainly will switch to Firefox (which I already use on my phone) if ad blocking stops working in Chrome. I'm really only on Chrome out of inertia - the developer tools in Firefox is just different enough that I haven't put in enough time to learn my way around it.
Just hit F12. Even faster, and it'll remember if you were in the console or the inspector the last time you closed it on that page. I use it quite a bit to just delete elements for pages I'm only going to visit once or twice, but don't want to spend time messing with my adblocker on.
When the news broke again of this change, I made yet another attempt to return to Firefox. Fortunately, I never returned. They’ve improved quite a bit in terms of resource usage and functionality, and I’m not looking back.
Unfortunately I seriously doubt it, given how many advocate for Google's efforts to make Web into ChromeOS, buy Chromebooks, and ship desktop applications wrapped in Electron.
