Can't install LastPass extension in Brave

Description of the issue:
I can’t install the LastPass extension in Brave.
So we have three computers in our home, all running (different distro’s of) Linux.

  1. Our main PC is running Pop_OS! 18.04, Brave (stable release: 0.66.101 Chromium: 75.0.3770.142) and has no problem with installing any extension, including LastPass.
  2. But on either of our laptops, the LastPass extension won’t install.
    Laptop A is currently running Linux Mint 19.2 (but I’ve tried this on Ubuntu 18.04 and Pop_OS! 18.04 as well, with the same result) and Brave (stable release: 0.66.101 Chromium: 75.0.3770.142). All other extensions install without problem, except! LastPass.
    Laptop B runs Ubuntu 19.04 and Brave (stable release: 0.66.101 Chromium: 75.0.3770.142). All other extensions install without problem, except LastPass.

Steps to Reproduce:

  1. Open Brave
  2. Visit LastPass on Chrome Web Store
  3. Click on Add to Chrome.
  4. a crx-file gets downloaded in the download-bar (other extensions aren’t visibly downloaded like this, see image)
  5. The crx-file get’s downloaded to about 5mb (of 12,5mb according to LastPass extension page) and stops
  6. An error pops up stating: There has been an error. Download interrupted.

Actual Result:
well… nothing… just errors and half downloaded crx files.

Expected result:
LastPass extension to be installed.

Reproduces how often:
Every single time, but only on our laptops, not our main pc.

Operating System and Brave Version:
see above

Additional Information:
Tried downloading crx-file through Firefox and dropping it in Brave’s extension-page, but I end up with an other error: CRX_HEADER_INVALID.


Ok, I don’t know if I should add this here or what b/c I’m using Win 7, not Linux.

I was able to add LP to almost all of my Brave persons except 2. I managed after SEVERAL reloads & tries to get it added to the 2nd to last one, but the last one, nope,

I keep getting this -!IlsiDSxA!xX9gfl7BXA3OWdyhYOwC6zaURM0GmuJvsuGQrTaDg6U

I also Xed out of that Brave person, loaded it again & still nothing, still same error.

Note: I was adding another extension “Nimbus” & I didn’t have issues with that one, so for now I assume this is an issue only with LP.

I was just about to start moving everything from Chrome over to Brave, but I need LP. I can’t live without it as much as I want to switch to another software.

I see no one has responded to this thread & it’s been 9 days.

I also see there’s many other issues with LP.

Are you guys fixing the LP issues once & for all?


I’m having the same issue with installing the lastpass extension on Windows Version 0.67.124 Chromium: 76.0.3809.100. I’ve been able to install other extensions but lastpass gives me the Download Interrupted error. I see in that it’s trying to download the .crx file but it appears that it gets a 403 Forbidden error when brave requests the extension file which results in the error seen at least that’s what it says when I right click on the failed download at the bottom of the screen and choose More Information. The 403 error however, maybe related to a bad “More information” link to than to the extension issue. The URL for the broken extension is:,crx3&x=id%3Dhdokiejnpimakedhajhdlcegeplioahd%26installsource%3Dondemand%26uc

I see that there are multiple reports of this same issue starting last April but none have been addressed.

I’ve also had success installing and using the lastpass extension on a different computer with the same version of brave so I’m not sure why I’m getting a 403 forbidden error on this Win10 computer when it works from the same network on another Win10 computer.
