Prerequisites

• I verified that this is not a filter list issue. Report any issues with filter lists or broken website functionality in the uAssets issue tracker.
• This is NOT a YouTube, Facebook or Twitch report. These sites MUST be reported by clicking their respective links.
• I performed a cursory search of the issue tracker to avoid opening a duplicate issue.
• The issue is not present after disabling uBO in the browser.
• I checked the documentation to understand that the issue I am reporting is not normal behavior.

I tried to reproduce the issue when...

• uBO is the only extension.
• using a new, unmodified browser profile.

Try reducing number of filters (subscribed lists) - it's possible your device does not have enough memory when uBO parses and compiles all lists (Startup is slow allReadyAfter: 4628 ms). What device is this?

6 or 8GB that is.

On my 6GB phone, Nightly, uBO dev, 140k network + 180k cosmetic filters, WebExtension process can take 3GB as per profiling.
1.5GB with default settings.
System shows 3.6 out of 6GB available when all apps are closed.

With 330k network + 370k cosmetic, maybe some stuff in background, out of memory situation is possible.

You enabled all regional filter lists?

[MusicaFM]

Yes

[stephenhawk8054]

Why? How many times do you visit Vietnamese and Thailand sites?

[MusicaFM]

Never, but I activate it just in case

[stephenhawk8054]

Don't do that. Just enable the lists of the languages you usually visit. The more lists you enable, worse performance and potential breakages can occur without any benefits.

To OP: check whether:
-- the issue occurs with default settings with default lists only
-- occurs on Firefox Mobile

Al OP: compruebe si:
-- el problema se produce sólo con la configuración predeterminada con listas predeterminadas
-- ocurre en Firefox Mobile

A joke or what, the values (1.5GB and 3GB) you've provided are insane, maybe you've confused real memory usage with virtual memory:

• Ublock origin uses 26.6gb of memory on firefox #994
• Using 24+Gb of virtual memory on Firefox/Ubuntu 20.04 #1532
• Cause memory leak on Firefox 107 #2401

I've checked on Firefox Nightly Mobile and Kiwi Browser: uninstalled Firefox Nightly Mobile, then installed it again, then installed uBO, then loaded 900k filters config, all while monitoring RAM usage, and RAM usage has incerased by only additional 300 MB for a while, then later has decreased much.

These gigabytes in FF profiler are bogus / virtual, I get similiar result to yours in FF profiler, but Android built-in system RAM monitor + built-in app RAM monitor + also 2 different 3rd party system RAM monitor apps show only 300-400 MB real RAM usage incerase for a while when loading high number of filter lists.

Good news then. I recall seeing such high numbers before on desktop, I will need to check if it was discussed, check my test method and try it again to make sure.

I'm not convinced for now. Memory fluctuates a lot. When I set my system monitor to higher refresh rate (0,1s), I see the memory increasing by nearly 1GB. On my default setting (2s), it's unnoticeable.
