Why does the profile folder double in size in a week?

Hello, I have a freshly installed computer:

Fedora 42
Brave 1.79.118 (Official Build) (64-bit)
Chromium: 137.0.7151.61

I installed Brave the normal recommended way.
Day 1 the “Default” profile folder is 128MB

Now, one week later it has (more than) doubled in size to 300MB… that seems pretty much.
I have installed 12 extensions, they should not take up a lot of space. (I can see Default/Extensions is unchanged in size from Day 1)

172MB is taken up by a folder Default/Service Worker.


My intention with posting this is twofold:

  • Put some attention at the possible accumulation of bloat in profile folder (maybe devs can improve Brave?)
  • Ask how profile folder size can be managed.

Best Regards
