In my experience, problems like that are almost always a matter of cookie/cache sticking around when it shouldn't or plugin interference. The only sites I ever have have blocking trouble with in FF are shitty web interfaces for local device configuration, old automatically generated webpages like from MS Access or some other super old enterprise abomination. I worked on a team of web developers that generally developed using FF and then tested heavily in chrome-- everything from simple pages augmented with JS to complex SPAs-- and the differences were pretty minimal.
Yeah that could possibly be it. If I run into again I could try clearing caches. And also wanted to mention that since firefox is what I use daily, of course I will mainly see issues there.
If I used chrome daily perhaps I would see the opposite (broken on chrome, works on firefox).
I get the same feel from DuckDuckGo. I use it, till it doesn't work, then switch to google when it doesn't. Of course google would perform better, as I only use it for the cases where DDG fails.
