Let me start off by saying that I adore FF. I had a period in my life where I used Chromium, but moved back to Firefox a few years ago and love what it represents and what it contributes to the community and world.

But I am concerned about the number of blatant usability issues that I've been experiencing with FF that have pushed me to the breaking point where I will have to give Chromium another go. But please help me not have to do that.

• Unable to drag a tab — Dragging a tab often causes the tab and address bar (but not the content) to become unresponsive and no longer flow properly (gets stuck) in the tabs list. Requires new window or restart to clear it up. Has been happening for a while.
• text cursor disappears sporadically with css scale down .— Open for 22 years, still sees sporadic reports, and still no resolution. Happens to me semi-often. Sometimes the cursor even goes to a random spot in the text and moves backward as I type at the end of the textarea.
• Random tab switching — Switching to another app and coming back to the FF window causes a given tab to re-focus, regardless of which one I was last using. Happens semi-rarely, started occurring recently.
• *edit: remembered another: FF often gets confused about drag-and-drop. In multiple web apps (Miro and eBay come to mind), I have to drag something into the FF window two times for it to be recognized by the app. It also sometimes randomly gets stuck in "drop" mode, requiring a non-committal drop for it to correct.

I only found that one Bugzilla report. Has anybody else been experiencing these? Especially the non-reported ones? Granted, I haven't opened reports on the others but ... they're all so hard to reproduce. If I'm alone then I understand why they haven't been fixed. But am I?

I'm currently on v146.0.1 as a flatpak on Kubuntu (Ubuntu + KDE Plasma 5.27.12 / Wayland). I am multi-monitor, one with fractional scaling.

*edit: Wanted to add that I have only one Extension in use: uBlock Origin
