createTab truncates URLs containing = sign in version 2.3.1 Firefox

[vintero1]

Describe the bug

The createTab command in Vimium appears to be broken in both Firefox and Chrome when the URL contains an = sign. Specifically, when trying to open YouTube videos, the URL is truncated at the = sign, causing the new tab to fail to load the correct page.

To Reproduce

Steps to reproduce the behavior:

1. Add a mapping: map g2 createTab window https://www.youtube.com/watch?v=8ZtInClXe1Q
2. Save options
3. Press the mapped key (g2 in this example).

Temporary Solution
Appending a dummy parameter after the = sign prevents the URL from being truncated:
map g2 createTab window https://www.youtube.com/watch?v=8ZtInClXe1Q&themeRefresh=1
