It totally depends on when you did try Firefox.

Two years ago Firefox was such a downgrade I concur.

One year ago the reverse was true and I switched to Firefox without regrets.

When was this? Recently it's great for me - better than Chrome - with the exception that some extensions are Chrome-specific (meaning you have to repackage them for FF).

Hey, can you point me to a good guide for repackaging extensions?

actually it may not work for all extension as chrome uses different api than firefox webextension standard api. I must say firefox extension api is far better than chrome one.

I tried to switch to Firefx once or twice before and failed.

Just managed to finally make the switch.

As silly as it sounds, feature parity on selecting and moving groups of tabs between windows was a big factor.

I still use Chrome at work for development, though.

i tried firefox and actually it is very better now. Last 6 month ago it was not good but now devtools etc is also good. Still not the best but its better than giving every data to google :D
