Brave extension and plugin for gmail not working

I have transferred my information from regular chrome to brave, and the extension to boomerang is installed, but not popping up and installed. I can’t use gmail with this, meaning I won’t even be able to use brave.

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

  • Brave Browser version numbers
  • Operating System version numbers

In a Brave Browser New Window, go to: https://www.google.com/. Click on the tune icon that is adjacent to the left end of the Brave Browser window’s URL address field:

In the resulting pop-down window, find and click on the Site settings button:

In the resulting Brave Browser Settings window at:

brave://settings/content/siteDetails?site=https%3A%2F%2Fwww.google.com

scroll down and Allow Javascript:

Also Allow JavaScript for:

  • brave://settings/content/siteDetails?site=https%3A%2F%2Faccounts.google.com
  • brave://settings/content/siteDetails?site=https%3A%2F%2Fwww.gmail.com

Tips regarding Brave Shields:

I have more success, with:

  • Brave Shields UP, but . . .
  • Either Allow All Cookies or Block 3rd Party Cookies, but NOT Blocking All Cookies
  • Allowing JavaScripts from specific sources, but NOT Allowing All JavaScripts
  • Trackers & Ads treatment: Aggressive (at first), and then incrementally relaxing that setting
  • Fingerprinting (aka footprinting) blocking: Strict (at first), and then incrementally relaxing that setting

I almost NEVER use:

  • All of Brave Shields UP
  • All of Brave Shields DOWN

Shields Basics

How do I configure global and site-specific Shields settings?

How do I use Shields while browsing?


If still having trouble, disable and un-install the Boomerang extension.

At brave://settings/clearBrowserData use the Advanced tab and Time range: All time. Then clear cache, cookies, history.

Exit / Quit everything and restart your computer. Then install Boomerang and try again.
