No idea if this is correct category or even correct site to post this but I noticed some problems with disconnect add-on (https://addons.mozilla.org/pl/firefox/addon/disconnect).
- I open 1 tab in firefox. In my example I had ~550MB of firefox RAM usage.
- I open 39 more tabs. My ram usage jumps to ~2260MB after it finishes loading them.
- I close these 39 tabs to be left with only 1 tab open. And here lies the problem:
a) in Firefox 77 RAM usage after closing tabs drops to ~1200MB after a while
b) in Firefox 78 RAM usage slowly drops to 2090MB - so it is pretty much the same as with 40 open tabs!!!
Disconnect add-on somehow blocks firefox 78 from clearing up RAM after closing tabs. In 77 it worked fine. Disabling add-on in 78 fixes problem too.
I’ve described this more thoroughly here:
No idea what could cause it because changelog for 78 does not mention anything about ram or add-ons changes.
Can I get more specific changelog than this:
