I have chrome installed. In the rare occasion that Firefox does not do a good job I just switch to chrome for that website and then go back.

This is usually the case if there might be forms or something like that. It's minor enough that it doesn't bother me.

Now, on the other hand, tab management is so much better with chrome and I've considered using Chrome for that reason alone. At work I do use chrome because I usually have 10-15 websites open at a time (for example I like to keep one tab group per ticket and every related item to it there).

I do use simple tab groups on Firefox but it's not good enough at least to replace my workflow at work.
