Pepe's Custom Newtab

👁 Demo:

NOTE: this is WIP, so consider it unfinished work

git clone https://github.com/PepeBigotes/pepe-custom-newtab

Type chrome://extensions/ into the URL bar.
Make sure developer mode is on (look in the top right corner).
Press the "Load unzipped" button and select the cloned repository.

If the extension fails to import or doesn't work, report the logged errors in the "Issues" tab.

DOES NOT WORK FOR STANDARD FIREFOX

Compress the contents of the cloned repository into a .zip file (use a tool like 7z or WinRAR). Do not include the .git directory.

This step needs to be done every time you want to apply the changes made to the extension.
Type about:config in the URL bar. Accept the warning and continue.
Search for xpinstall.signatures.required and make sure it's set to False.
Type about:addons in the URL bar.
Click the gear icon and then "Load add-on from file"
Select the .zip file and make sure it loads properly.

If the extension fails to import or doesn't work, report the logged errors in the "Issues" tab.

LACKS PERSISTENCY: YOU NEED IMPORT THE ADD-ON EVERY NEW SESSION

Same as step 1 for Firefox Developer
Type about:debugging#/runtime/this-firefox in the URL bar.
Open the temporary extensions menu if it's closed and click "Load Temporary Add-on".
Select the .zip file and make sure it loads properly.

If the extension fails to import or doesn't work, report the logged errors in the "Issues" tab.

Work in progress...
