fixing url query

[Vincent-vst]

Why this pr ?

I had a problem when I typed for instance "discord.com/app" (which is valid url) but I wasn't redirected to it (because it didn't start with http), so it just started to google "discord.com/app" which is not what I wanted. In this commits :

• I validate the urls using a (big) regex
• if the url is valid, it is sent to browser.tabs.update() and that fix my problem.
• if not, it is sent to "https://www.google.com/search?q=" + encodeURIComponent(query); like before.
  basically a lot of words for just adding a if statement

Quoting from the doc :

I had to append http to urls that doesn't contain it because firefox extension is not super friendly with "valid urls".

Fully-qualified URLs must include a scheme (for example, 'http://www.google.com' not 'www.google.com').

For security reasons, in Firefox, this may not be a privileged URL. So passing any of the following URLs will fail:

    chrome: URLs
    javascript: URLs
    data: URLs
    file: URLs (i.e., files on the filesystem. However, to use a file packaged inside the extension, see below)

Other info

Something that I need to mention is that a query that doesn't start with http* is redirected to http not https. For instance : if I type www.google.com arcfox will send me to http://www.google.com and then the google server will redirect me to https://www.google.com The reason behind this is that I cannot know in advance if the website is in http or https.
