I use Vivaldi as an alternate browser, particularly for cross browser testing as it’s based on the same engine as Chrome, and pretty much everything that isn’t firefox.
And I’m forced to use Chrome at work. Can’t say I’ve noticed any advantage of Chrome over FF, or any major new features in Chrome since back when I was using it.
Firefox’s market share is kind of sad, but I put it down mainly to three things.
On the FF side, they had a very rocky patch about 5 years ago where they had bad performance and some breaking changes that annoyed a bunch of users, and that’s when a lot of people switched to Chrome and also recommended that their friends switch… which created a kind of snowball effect that was essentially the mirror image of the effect that got everyone to switch to FF in the first place.
Mobile and specifically Android became a big thing, and google had a massive advantage in that space. FF mobile seems fine now, but it was either non-existant or terrible for a long time, and by the time it got into decent shape Chrome had an unassailable lead on their home turf where they’re installed by default. This also has a knock on effect on the desktop.
Google has a shed load more money and power than Mozilla, so they’re basically in an unassailable lead at this point, unless they do a MS and abandon development on Chrome and let it stagnate… which I don’t see them doing.
That said, I’m not militantly advocating that people should switch to FF. Chrome is a very nice browser, and if people are happy with it then it’s fine. But I personally think that these days there’s effectively nothing to choose between them, unless you need specific things like instant translation.
But if people left FF back when it was a bit janky, it seems much better now. And it’s kinda nice not to have to worry to much about privacy, if such things matter to you.
But, other than privacy, I can’t think that Mozilla will be able to introduce some kind of killer feature that will suddenly get everyone to switch back. Even if they did, google have the resources to just copy it pretty quick.
I just think it’s good if there’s a reasonable competitor to Chrome, so if FF died away entirely I don’t think that’d be good for anyone.
