And everyone wonders why Firefox has less than a 3% market share
EDIT: Also here are actual benchmark numbers for a more quantitative analysis: https://www.pttrns.com/fastest-browsers-for-windows-10/
What’s wrong with Firefox?!
I will get downvotes for this, but you asked:
Firefox is slow and glitchy, and lots of websites break or just perform worse than chrome.
Firefox used to have ~30% market share around 13 years ago, when it was better than the competition. The reason it’s dropped so significantly is because better options came along (chrome)
I understand the arguments about Google controlling the internet through chromium. I would love for Firefox to actually be the best browser, but it’s not.
And since Firefox users ignore these citisisms and act like it’s the best browser ever, there is not enough pressure for Firefox to actually fix these issues, since their users act like it’s already the best thing available and perfect in every way. It’s very similar to why Linux doesn’t catch on.
I have tried just about every browser available. I will use the one that performs the best and has the best features. Currently that is Brave, which is a great browser, but I would absolutely jump to Firefox if things changed and it became the best performing option.
Well in my experience, Firefox is definitely slower, and it is immediately apparent that it is much jankier than Chrome. And as the many posts I linked above show, I am not the only one with this experience.
Also it’s hilarious how I give a source and now the goal posts are moved and the benchmarks are “synthetic”
CPU and GPU benchmarks are also “synthetic” but they still show actual differences between what is being tested.
Qualitatively and quantitatively, Firefox is slower.
