Ask HN: Any Decent Firefox Alternatives?

I've been using Firefox for a while now, but I have some issues with it:

1. I need to switch to chrome for various products such as Google Meet (works on Firefox, but I ran into performance (call quality) issues).

2. I often find sites with bad support for Firefox, and I need to again open a second browser (usually Chrome) to check them out.

3. It seems that in the past... long time, they have a talent of making Firefox worst. I still like it if it wasn't for the other 2 issues, but who can tell in 1 year.

Due to the above I was looking for a browser (one, I don't like having multiple on my machine but not sure if the Google Meet performance upgrade is just in Chrome or Chromium) which is as fast as Firefox, has a nice UI and preferably a bit more privacy oriented (not much, just a bit more).

Any ideas? (Currently checking out Vivaldi, but read a lot about performance issues + I don't really like the default UI yet).

Used it for some time a while ago - but I don't know, didn't enjoy it too much. Can't really remember why tho.Might give it another try.

Microsoft Edge.

Chromium based, has vertical tabs (window border can be switched off too) via flags. Works great.

Vivaldi promised many things but its performance sucks indeed and I hate the fact that the browser has bullshit features like Phillips ligths controls or something.

I use Brave, with the Rewards junk, and it has maintained its speed that every other browser I've used loses as it fills up with caches, history, extensions, etc.

For desktop- Microsoft Edge. For Android- Bromite, Brave.
