Where are extensions stored once they've been installed to Chromium?
7 Answers
Extensions are (usually) stored at ~/.config/chromium/Default/Extensions. Here's an example featuring the amazing adblock:
jake@daedalus:~$ cd .config/chromium/Default/Extensions/
jake@daedalus:~/.config/chromium/Default/Extensions$ ls
gighmmpiobklfepjocnamgkkbiglidom/ jggheggpdocamneaacmfoipeehedigia/
jake@daedalus:~/.config/chromium/Default/Extensions$ cd gighmmpiobklfepjocnamgkkbiglidom/2.3.1_0/
jake@daedalus:~/.config/chromium/Default/Extensions/gighmmpiobklfepjocnamgkkbiglidom/2.3.1_0$ ls
adblock.js background.html blacklisting/ button/ functions.js img/ jquery/ manifest.json pages/ whitelister.js
adblock_start.js blacklister.js broadcast_channel.js filtering/ Icon.png Info.plist _locales/ options/ port.js
To see it in your file browser, make sure you can see hidden files (View > Show Hidden Files). Or, do like Gaurav says and type in the path after pressing ctl+l.

While the usual profile path for Chromium-based browser is in ~/.config/chromium/<name of profile>
This is wrong if you under these circumstances:
- have multiple users in Chromium
- specified the user profile path in Chromium
- config folder is different if you're using app containers (snap/Flatpak/AppImage).
Visit chrome://version/ in your Chrome and check "Profile Path" for the definitive answer.
