Mozilla plans to introduce a new feature in Firefox 67 Stable, το οποίο στοχεύει στη βελτίωση της χρήσης της μνήμης του προγράμματος περιήγησης σε συνθήκες χαμηλής μνήμης.
Browsers use much more memory than they did a decade ago. This is partly because websites have grown significantly in size but also because they have changed function programs browsing.
It is no longer uncommon that individual tabs can use hundreds of Megabytes of memory and there are cases where memory usage is catching 1 Gigabyte in some of them.
Memory usage, especially on low memory devices, is a priority for browser manufacturers. If you are running Firefox or another browser on a system with 4 or 2 Gigabytes of RAM, you may experience problems due to large cache if you open several or the right kind of websites.
The concept of loading tabs into a browser to free up memory is not new. Extensions for Firefox, such as Dormancy, Suspend Background Tabs, BarTab, or Unload Tab (not all are now compatible with Firefox 57 or later), or Google Chrome Lazy Load Tabs, TabMemFree, or Tabs Limiter, have been around for years.
Although Mozilla has significantly improved the unloading of tabs in recent years, Firefox 67 plans to introduces a new feature to unload unused tabs to improve memory and reduce the number of crash conditions. The original error report for excessive memory usage is dated for eight years, but work on the new feature began seriously just before.
Mozilla uses a simple list of priorities to determine which tabs to get rid of when the conditions trigger the application of the new feature (from lowest to highest)
1. Normal tabs
2. Pinned tabs
3. Regular tabs that reproduce sound
4. Pinned tabs that reproduce sound
This feature is already available in Firefox Nightly. The Firefox 67 will be released on 14 May 2019 on the Fixed Browser channel, according to the release program.
Google has implemented a similar feature in the company's Chrome browser. 2015 was introduced, like Automatic Tab Discarding at settings of Chrome, and discards tabs from memory if system memory reaches a certain limit.
