I say that as a web developer myself. Gecko has become problematic to work with. It’s not the web devs fault that Gecko is now full of odd quirks.
I used to dev for Firefox, then test on Chrome. The amount of times I was looking for a non-existent bug in my code just to realise it works fine on Chrome and it’s actually a Gecko bug not respecting a specification was a major factor in my choice to drop Firefox as my daily drive.
And the irony is that one of the best documentations for web specifications is made by Mozilla.
Good for you!
