Base64 Decoding Userscripts
Only converts base64 links that ends with = when you right click
Aggressive Base64 Decoder
Because some base64 links don't end with =, the following script is more aggressive, but it can break some UI stuff.
Automatic Base64 Decoder
Every 500 ms, this userscript will auto check for, find, and decode all base64 links. This might be redundant for those who don't often view these kinds of links on a regular basis, but this script is more faster in the sense the process is automated entirely (no right clicking to decode).
Base64 "Extensions"
These decode and encode one link at a time, and auto send you to the link that is decoded. I would only recommend them for people using sites where links are not easily auto-decoded (Discord), or they only encounter a few Base64 links regularly (not a whole website worth or anything like that).
Base64 Decode Extension
Base64 Encode Extension
To add these, you must right click your favorites (Bookmarks Toolbar if you have Firefox) bar (underneath the URL Bar). Click "Add Page" ("Add Bookmark" if you have Firefox). Change the name to "Base64 Encode", then put the code pasted above into the "URL" form. Add another page using "Add page" or "Add Bookmark", but change the name to "Base64 Decode" and add the code pasted above into the "URL" form.
