What alternative to you suggest? I really don't like Firefox, and chromium base browsers are way more comfortable to use. I currently use bromite which is awesome.
I'd say use Firefox for 3 months, there's some adjusting needed but it's really grown on me. Bromites last and final update was 8 months ago, so definitely find a replacement. Mull is a fantastic mobile browser, privacy focused and even has extentions. But Ladybird is a new browser in the works which isn't chromium or FF based, maybe give that a try whenever its released as well.
What excactly dont you like about FF?
The ability to add addons (on nightly, you can even add any Desktop add-on you like), tab containers / cookie jars, or the flawless syncing to desktop, including passwords and bookmarks?
For me it's lack of convenient hotkeys and keyboard-based navigation. Used Vimperator on FF until they killed it. Now using qutebrowser, which uses qtwebengine, wbich uses outdated chromium. Sad story.
