(Firefox users : Read the last paragraph of this article)
If you are an old Firefox user then you must have already used this feature. Previously Firefox used to ask users to save open tabs before closing the browser window. So that next time when you re-open your browser you can directly start from where you left.
Google Chrome never had this feature. If you have moved from Firefox to Chrome and if you are missing this feature then you can get it back using OneTab.
OneTab is a Chrome extension which allows user to save all open tabs in a list and restore them later, one by one or all at once. It can not only save you from temporary bookmarking but also reduces the memory usage.
If you have too many tabs open and you know that you are not going to need them for sometime then you can simply click on the OneTab button and it will save all open tabs in form of a list. Closing open tabs will reduce memory usage. This extension is clean and pretty easy to use.
For Firefox users:
Firefox no longer asks for saving open tabs. But you can still save all the open tabs on Firefox as well. For this, first go to Options ->General->When Firefox starts. There select Show my windows and tabs from last time from the drop-down list and click Ok. After this when you want to save all open tabs, click on Firefox button at the left-top corner and select Exit (File -> Quit on Ubuntu). Clicking on the Close button will not save open tabs.
