Unless you were running Firefx with outdated uBO filters, I doubt that. Vivaldi is a memory hog for me.
Strange, it's literally half of Firefox with equivalent tabs.
What platform? Extensions? Any about:config changes?
Windows 10, 3200MHz CL16 32GB, Ryzen 5 3600XT.
Extensions on Vivaldi are Bandcamp volume control, Bing unchained, and tubebuddy.
Extensions on Fox: Firefox color, DDG privacy essentials, Ublock Origin.
Same tabs open on each browser.
YouTube, Spotify, Lemmy.world, and FB messenger.
Methodology: played YouTube videos in each with all other tabs idle to ensure they were actively using system resources.
FF: 1361MB (active) V: 764MB (active)
That's literally half. Also Firefox never seems to want to give back RAM, whereas Vivaldi drops back down by a factor of 1/7 when the video is paused. Fox only managed to give up a measly 60ish MB of it's 1361.
FF: 1306MB (idle) V: 628MB (Idle)
Edit: I believe ublock being installed on FF is justified since I find the native ad blocking of Vivaldi to be just as good, namely in YouTube which is my primary concern. If you want an AdBlock free test that only wins points in Vivaldi's favor for packaging it into the browser.
I just tried it and Firefox ESR uses ~800MB with a bing tab, a youtube tab focused and playing a video, a lemmy tab and a github tab. I’m running it on GNU/Linux, and I toggled dom.suspend_inactive.enabled in about:config. Edit: it also doesn’t really matter how much RAM it uses, it’ll unload tabs if the system is low on memory. Firefox is also faster for me.
