Add a user-configurable memory limit

[kolniu]

I'd like to see a new feature in Firefox.

Users should be able to set the maximum amount of memory Firefox is allowed to use.

- - -
➡️ | This option should be available in Firefox Settings
➡️ | Memory Limit Options

Memory limit options

Option 1: Fixed memory limit

• 512 MB
• 1 GB
• 2 GB
• Custom value

Option 2: Percentage of installed RAM

• 10%
• 20%
• 30%
• Custom value

Important

Firefox should enforce this limit itself and manage its memory usage accordingly.

- - -
➡️ | When the limit is reached, Firefox should take appropriate measures to stay within the configured memory budget, for example:

• Unload inactive tabs
• Reduce or clear internal caches
• Release unused memory
• Reduce background activity

The goal is to keep Firefox within the user-defined memory limit instead of continuously increasing RAM usage.

- - -
➡️| This feature would be especially useful for:

• Computers with limited RAM
• Older hardware
• Virtual machines
• Embedded systems
• Users running multiple applications simultaneously

- - -
Many users have been requesting this feature for a long time.
Thank you for considering this feature.
