Hi, Instead of using the embedded feature "group tab" of firefox I am keeping a window for each tabs' group I want, mainly because of accessing the "group tab" (ctr+shf+e) + click on the desired group + wait for it to load is quite slow on my system. However by keeping several windows my RAM suffers and either by using "tabs' group" I don't see much difference in the RAM usage. Understanding that there is no way to have a low RAM usage and no load time (for example the tabs loading after clicking on one group of "tabs group"), is there a way to put a limit to the RAM usage of the "tabs group" feature ? For example, beyond 500mo of RAM allocated, all the subsequent tabs' group added won't be store in RAM anymore (where 500mo can be configured). If not what is the best habit ? "tabs group" or several windows ? Thanks for your spent time on my question, I hope I put it clear. And thanks for this great browser you made ;) <3 firefox Respect,
