Memory and Energy Saver
Use Foom’s resource-saving tools to keep tabs responsive while extending battery life.
How do I use the Memory and Energy Saver features in Foom?
To save your computer’s memory and help active tabs run smoothly, Foom deactivates tabs that you aren’t currently using. When you access an inactive tab, Foom automatically reloads it.
Enable or disable Memory Saver
- Launch Foom
- Navigate to Menu → Settings → System → Performance
- Toggle the Memory Saver option on/off
Keep specific sites active
You can add exceptions to keep specific sites active.
URL format for site exclusion: [scheme://][.]host[:port][/path][@query]
- Next to Always keep these sites active, click Add
- Enter the web address
- Click Add
If you want to create an exception for:
- Entire domains and subdomains: Exclude the URL scheme. For example, entering foom.com matches and prevents deactivation of subdomains like account.foom.com or talk.foom.com.
- A specific subdirectory: Include a dot (.) before the URL host. For example, www.foom.com/blog matches and prevents deactivation of all Blog pages, but will not prevent deactivation of the main www.foom.com pages.
- URL host and query components: Asterisks (*) can be used as wildcards that match any character(s). For example, https://* matches and prevents deactivation of all https sites and youtube.com/watch?v=* matches and prevents deactivation of YouTube videos.
Note that wildcards for prefix, suffix, or substring matches of the URL host component are not supported. For example, *oogle.com or google.com/* won’t match.
Change inactive tabs appearance
When Memory Saver is on, inactive tabs show a dotted circle around the favicon.
If you prefer to disable this appearance, go to Settings → Appearance → Tabs and toggle the Inactive tabs option off.
How do I use the Energy Saver feature?
To extend your device’s battery, Foom reduces image capture rate and other background tasks. When Energy Saver is on, it works automatically whenever your device is unplugged, or when your battery is low. Energy Saver does not turn on when your device is plugged in.
Enable or disable Energy Saver
- Launch Foom
- Navigate to Menu → Settings → System → Power
- Toggle the Energy Saver option on/off
