Dear Mozilla,
I've been using Firefox, loyally, since before it existed. I used it when it was called Firebird, and Phoenix, and before that I was using the Mozilla browser. Occasionally - maybe once a month or so - I'll fire up some other browser for a specific task, but Firefox has always been my standard, everyday, all-purpose browser. The interface is clean and simple, the extensions are beautiful, I like the focus on privacy and putting the user in control. It just - works the way a browser should.
Until now.
The Quantum leap was, for me, not a good thing. True, pages rendered faster. But that performance came at a price: pages sometimes crashed, or slowed the whole system to treacle (Trello was particularly badly affected, presumably because of something in their Javascript - but whatever it was, it didn't affect other browsers). Nevertheless, I persisted. I told myself that Quantum had been a huge change, and teething problems were only to be expected. The next major update, I thought, would cure some of these ills.
Sadly, the opposite has happened. The "next major update" has landed, and while it has cured whatever ailed Trello, it has reduced several other sites to "completely unusable". As in, it simply no longer renders the page content at all. It will load a frame, or maybe a background image, but not display the content; or the content will disappear when I scroll. This happens across multiple sites and multiple computers, with and without extensions enabled; so I'm picking Firefox as the culprit.
(The content is loaded, it's still "there". It's sometimes possible to select it, by clicking and dragging with a mouse, and sometimes when this is done it will remain visible after deselecting. But sometimes not. At any rate, this is not an acceptable workaround.)
It is therefore with a heavy heart that I have decided, I can no longer wait for Firefox to get this excrement back together. Right now I have little choice but to adopt Chrome at work; for home use, I will probably prefer Vivaldi. A lot of people speak highly of Palemoon and Waterfox; I may give one or both of them a try within the next month. But Firefox, most sadly, is a broken vessel.
Goodbye. I wish you nothing but the very best of luck in the future; but from today, I'm no longer a user. I just don't have the time to deal with this level of crap.
