when firefox started lagging because there were to many open tabs, i took advantage of that lazy loading feature and restarted the browser, causing all tabs except the active ones to remain unloaded.
now i installed an extension that suspends tabs that are not visited for a while. that keeps active tabs to a few dozen, so i never have to restart any more because of that.
apparently i have more than 3700 tabs (spread over a dozen windows, each window for a somewhat defined activity, which should make cleaning out a bit easier, since tabs are related, although i would still have to take some time off to clean through all off them).
