And since you won't be able to modify web pages, it will also mean the end of customization, either for looks (ie. DarkReader, Stylus), conveniance (ie. Tampermonkey) or accessibility.
I loved it around 20 years ago, but somewhere towards the mid-to-late 00’s it got bloated and slow. It was like that probably until recently if i’m being honest. I heard it’s maybe better now but i’m not sure.
It got better years ago. I stopped using it around the late 00's myself because it was consuming all of my RAM. But I started using it again about 5 years ago and it's better than chrome now.
I bailed from Firefox for about a year after they added the godawful Firefox button (4.0 maybe?); then I got fed up with Chrome and by that point there was an extension to remove the Firefox button
I used it up to the early 2000's and it just seemed to slow down. I recently did a series of synthetic benchmarks on all the browsers and Firefox was the slowest of the batch. It's still the only browser left not built on chromium I think. Opera GX was the fastest in terms of benchmarking.
Ahh that’s unfortunate. I remember sometime within the past couple years or so, people were talking about some “big new update” for FF that supposedly made it better. I tried it, and it was very slow, offputtingly so. So i take everything with a grain of salt now.
