Brave Browser is so Slow

Please edit your Original Post (“OP”) above, to include:

  • Brave Browser version numbers
  • Operating System version numbers

Please be prepared:

  • Make note of Brave Browser Settings that you would manually restore (Yeah, it is a lot of paperwork. Saving screenshots, will be easier.)
  • Back up bookmarks (and tabs, as bookmarks)
  • Back up passwords

Please back up your BraveSoftware folder:

%LOCALAPPDATA%\BraveSoftware\Brave-Browser\User Data\Default\


Please use the Guest Profile or create an additional Brave Browser Profile, for testing.

Menu → More tools → Open Guest profile
Menu → More tools → Add new profile

If your issue is resolved with either of those other Profiles, then the Profile that you have been using, may have one or more settings that contribute to the cause of your issue.


The “File System” folder - can grow to be LARGE and require attention:

%LOCALAPPDATA%\BraveSoftware\Brave-Browser\User Data\Default\File System\

Ref.:

Folder ...appdata\local\BraveSoftware\...\File System\ is too big (12Gb!) - #3 by grandemonio


One or more extensions that you have installed, might be problematic.

Note, how a Brave Browser user figured that out:

Bad Performance on MacOS with 1.74.48 - #8 by nintendork07

Note, that BB user learned to fully restart BB, in order to test effectively.


Too many Tabs.
