Many pages will have various tracking codes and therefore, the tab's URL may not exactly match with the canonical URL. This extension should demonstrate the right behaviour for bookmarking by using the canonical URL instead of the raw URL.

Sorry for the title, I couldn't find a better name for it.

Short description + Steps to reproduce

When on a website like here on github, press the mouse (and keep it pressed), go over the TST sidebar, release the mouse, and go back to the website. The mouse still is detected as "mouse button pressed". This does not happen in the Bookmarks, History or Synced Tabs sidebars.

Firefox's "Remember logins and passwords for websites" option is cleared every time browser is started.

I understand the addon clears this checkbox, as the previous version did, however I use Firefox to store (some) passwords and I want to re-check it.

With the old version installing the add-on cleared the "Remember passwords" checkbox, and then re-checking it would leave it on. With this ve

const startsWith = (x: string): Predicate<string> => (y) => y.startsWith(x);
