> And Mozilla usually ignored user protests while pointing at telemetry, and did whatever they wanted to, users be damned.

When I worked on Firefox, most of the changes happened exactly because user research determined that users wanted them and/or that not having them hurt the product. We changed the tabs at least once because users thought that the old shape of tabs made the browser feel slow (true story, sadly). We changed the add-on API (after having warned add-on developers for at least 6 years) because the old API was incompatible with multi-threading, multi-process, sandboxing, which in turn was really bad for both performance and security.

I'll absolutely grant you that Mozilla hasn't been very good at communicating these choices, but again, the sheer hostility of tech crowds is exhausting.

You refer to important security improvements as "vague technical reasons" and you switched to Vivaldi, a browser that is based[1] on extended stable Chromium, which is not "recommended for any team where security is a primary concern"[2].

It seems you don't care about security.

I don't know but I've been using Firefox since forever and I can't even recall the tabs changing at all. Of course they have changed many times over the course of years, but that happens in every browser. I don't know what happened to tabs that affected you so badly? I feel like it's an excuse for some people sometime that if some little thing in the UI changes that they claim their whole flow is now compromised so that is the reason they are now using this other software, where the same stuff happens as far as I can see.

In the latest version they changed something AGAIN, when you drag a tab too far to the left it's pinned automatically. Literally nobody asked for it and it makes me so angry, god I hate Mozilla. I only use Fiefox because it's the last browser with Manifest V2 (I have a lot of these add-ons) and as an add-on dev they made me even more angry with having double standards regarding their shitty add-on review system.
