2. Restart computer.
3. Relaunch Firefox Dev version (70.0b8 (64-bit)

This has been reported on Windows 10 machines as well as High Sierra 10.13.6.

Actual results:

I could not reproduce this issue on Windows 10 Pro 64-bit on Firefox 70.0b8 (2019091964641) and 70.0b11 (20190930132843) or on macOS High Sierra 10.13.6 Firefox 70.0b8 (2019091964641) and 70.0b10 (20190926005616).
I've tried the following scenarios:

1. On a new profile, installing the Momentum add-on, selecting "keep changes" in the extension popup and then restarting the PC and launching the browser.
2. On a new profile, installing the Momentum add-on, providing the extension with a username and then choosing not to log on. Restarting the PC and launching the browser.
3. On a new profile, installing the Momentum add-on but not clicking "Okay, Git It" on the second pop up. Restarting the PC and launching the browser.

I've also went the extra step in trying to see if there is a difference in launching the browser with the profile manager or not but the results were still unsuccessful.

Could you please try and reproduce this using a new profile?

Do you have any other extension installed on the profile you've been using?
Are there any extra steps performed when installing the add-on - like adding logging in?
