Impossible to consent to privacy policy, if consent is not given on installation/update of the WebExtension

Hi,

Upon installing (or updating to) the Snowflake WebExtension 0.8.0, a prompt offering to consent to Snowflake's privacy policy is opened in a Firefox tab.

If one closes Firefox or the consent prompt tab before giving consent, there is no obvious way to access again the consent prompt when opening Firefox at a later time.

Sure, one could try and find the consent prompt again via Firefox's menu History > Recently closed tabs. But it seems overly convoluted. Moreover, if one does not notice immediately that one have missed the prompt and that Snowflake is thus disabled (which happened to me, as I was in a rush when the prompt was displayed), the recently closed tabs part of browsing history will have been overwritten.

Steps to reproduce:

1. Open Firefox with a clean test profile
2. Install Snowflake from https://addons.mozilla.org (which will open the consent prompt in a new tab)
3. Close the Firefox test profile
4. Open again the Firefox test profile and try to access the consent prompt

Other information:

• OS: Arch Linux
• Firefox version: 124.0.2
• Snowflake version: 0.8.0
