Hi everyone Since the last Firefox update to 70.0.1, I noticed that my Firefox was getting sluggish, sometimes taking several seconds before finishing rendering a page and allowing me to click on links. After looking in the processes, turns out that WebExtensions was gobbling up nearly 21GB, not to mention several other processes for rendering the tabs! It was probably swapping memory all the time... After turning off my uBlock addon (and restarting the browser, of course), Firefox is now as responsive as I was used to and WebExtensions is now ~2.5GB. Not sure whether this is due to the newly introduced privacy protection facility within core Firefox, that uBlock ballooned/slowed down like that. Anyway, still got my NoScript and PrivacyBadger addons active.
