Trying to switch from Chrome to Safari. Realized Gmail gets reloaded all the time due to "significant memory" messages. Tried Safari Technology Preview (STP) -- seems to happen less, but is still happening.
@TabascoMuffin seems from your cross-out, are you saying it's still happening on the newest STP?

Another question, how is everyone dealing with website notifications, like the Safari Push Notifications that MacRumors for example offers? I just realized when I click on one, even though I have STP set up as the default browser, the system insists of opening up Safari (not-STP) and loading the page in that. Although just now it opened Safari and actually loaded the page in both Safari and STP.
When you load a page with more than 2GB RAM on STP 119 or 14.0.3 on Big Sur, it becomes unusable, very laggy, and the message "safari using significant memory" appears.
Tested on MBP16 and iMac 2020.

However, on STP 120 I was able to load the same page to 2.6GB RAM and then got the "safari using significant memory" message. But this time, the page wasn't laggy and I could still scroll down and load more pictures for example.

It's not happening on Chrome nor Firefox.

Still waiting on that translate feature that was mentioned years ago...
I got tired of waiting and moved to Brave. It's got better Ad blocking and does google translate while being fast.
Translate feature has been available in Safari since the Big Sur release (and earlier, with the technical previews)

Two weird issues with this release:
[LIST=1]
* Can only sporadically get Command-N to open a new window. Quitting and restarting helps, but then it fails again.
* Pinned tabs don't "stick." I create them in one window, and they don't appear in the next, or when I restart.

Make sure to alert Apple....

ANYONE❓⁉️❓
For Q #1: Yes...if I read you correctly; when I open a website in either it ONLY opens in that version of Safari.
For Q #2: Just received an update yesterday. The updates arrive just as per other Apple applications. Check your Prefs/updates .
Hope this helps.
