I'm a Firefox user for about 20yrs (since Firefox 3);
but too often I have to use Chrome, as so many sites only work properly on it; Firefox is really buggy or laggy on those websites;
For a time, all those AI chat web pages were just very slow on Firefox even with very little context, whereas Chrome only gets laggy when there is a lot of context.
Are you really sure it’s not because of an add-on?
If I remember correctly, Mozilla has said that about 95% of all pages that don’t work aren’t due to Firefox, but to an add-on.
I use Firefox exclusively and don’t usually notice that pages don’t work. When that happens, as I said, it’s almost always an add-on that’s to blame. And I dont notice its buggy or laggy. So could be good check your addons next time.
Here are some cases where Firefox really sucks: some of them are specific CSS styles, some are downgraded features, and some of them I just don't know why. As I mentioned here, the ChatGPT web and Gemini web used to be very laggy for no reason—or maybe it was just a bug for me?
I don't think any of this is caused by add-ons, though.
But it's getting better, and most of those problems are just gone;
Same here, but when a site completely fails in Firefox I either A) use my phone because mobile Firefox occasionally works or B) use Ungoogled Chromium.
You can report websites that don't work, or block Firefox, to Mozilla at https://webcompat.com/. Mozilla engineers try to reach out to the website developers or ship site-specific workarounds in Firefox.
Not using many extensions on my case, but Google meet remains unusable for a long time, sound is horrible during meetings. Chrome on the other hand works fine
