In this case, the discarding is postponed until another tab requests a new check. In rare situations, a tab may request to be discarded and gets rejected for one of the above reasons. So a background tab cannot ask for discarding more than once. The extension requests the check when a tab moves to the background after the discarding period. It only checks the discarding conditions when necessary to optimize the performance. However, in some cases, the extension may not discard a tab when you expect so. The number of open tabs that have not yet been discarded is less than the maximum number, as set in the options page by the user.In this case, there is a tooltip text on the action button of the tab explaining the reason. The tab matches a condition that prevents discarding, such as having the “Do not discard this tab” option checked in the popup window.Two main reasons why the extension skips discarding are as follows: It seems sometimes the extension simply just not discard a background tab that it should. Tab discarding allows your browser to maintain a large number of open tabs without causing the system to become slow or unresponsive. However, it is still listed in the tab bar and can be reopened by clicking on it. The content of a discarded tab is removed from memory and is not visible to the user. Tab discarding is a feature that allows the browser to automatically discard tabs that are not being used to free up system resources such as memory and CPU. The extension continuously monitors tabs and requests the discarding of inactive ones when appropriate. This native method helps prevent unwanted activities from running in the background and potentially slowing down your browser. A discarded tab is removed from memory and can no longer run any background scripts. This discarding helps reduce the amount of memory and CPU usage used by these inactive tabs, which can lead to better overall performance. The "Auto Tab Discard" extension is designed to help improve the performance of your browser by discarding tabs that have not been used for a certain amount of time. Tab Wrangler is a widely popular tab management extension available for Chrome, Edge, and some other Chromium-based browsers. 1 Use Tab Wrangler To Suspend Background Tabs In Edge and Chrome. What is the "Auto Tab Discard" extension and how does it work? Use Tab Suspender for Edge and Chrome Use New Tab Suspender for Firefox Make sure to give all of them a try, and then choose based on your liking. Provides options to prevent certain tabs from being discarded, such as pinned tabs, tabs with media playing, and or pauses discarding when not connected to a power source. ![]() ![]() Can be set to exclude certain websites from being discarded.Allows the user to manually discard all or some of the tabs in the current window.Automatically discards tabs that have not been used in a certain amount of time.The extension also allows you to configure an exception list and specify types of tabs that should not be discarded, such as pinned tabs or tabs that are playing media. When a tab is discarded by the native method, it is completely removed from memory and does not use any resources, but it can be restored to its previous state, including preserving page state such as scroll position. ![]() This extension uses the native method for tab discarding, which means it does not suffer from the same issues as other extensions that use custom methods. Ability to specify whitelisting for a specific URL or entire domainĪny help is greatly appreciated, I think I'm going to drive myself mad if I don't find a suitable replacement.The "Auto Tab Discard" extension is designed to automatically discard inactive tabs after a specified amount of time to reduce memory usage and prevent background scripts from consuming computational resources when it is not in use. I mention this because I know some of these add-ons / extensions can be prone to failure so the upside of that method was that I could still access the original URL from the bookmarks I saved of my open windows - it was laborious, but the tabs were still recoverable - I wouldn't want to use anything that obscures the original page's URL so that it would be unrecoverable if anything goes wrong.Īlso would very much prefer a project that's open-source to verify the privacy practices and that the URLs aren't being sold or anything.Ī few other things that were useful and would be nice-to-haves: The way Great Suspender seemed to do it was to redirect to a blank page with a generated URL that included the original URL as part of it. I'm wondering if Firefox add-ons have anything fairly comparable (tab-management stuff that allows suspending the tabs to save resources). I generally have a lot of tabs open at once and I constantly find Edge tabs start spinning when there are relatively few open (I would say I could have a few hundred more open using the Great Suspender) and it isn't quite as full-featured. I had been using the Great Suspender and since it got killed I've been using Edge and its built-in sleeping options which are.notably inferior.
