i2p.plugins.firefox VS Tassel

I use Firefox with the I2P In Private Browsing webextension for mixing I2P and clearnet browsing in the same browser, and I use i2p.plugins.firefox for I2P-only browsing.

The only package that directly incorporates an I2P-specific browser profile is the Easy-Install for Windows. To get an I2P-focused profile manager as a Debian package, you can use https://github.com/eyedeekay/i2p.plugins.firefox/releases/download/1.0.9/i2pbrowser_1.0.9_amd64.deb. This is exactly the same profile manager code as the Easy-Install bundle, but it is decoupled from the I2P router itself. To make the router launch it for you, add routerconsole.browser=/opt/i2pbrowser/bin/i2pbrowser to your router.config file.

If you want the benefits of the Easy-Install on your existing Classic install, your best option is to use a console plugin IMO. You can download: https://github.com/eyedeekay/i2p.plugins.firefox/releases/download/1.0.8/i2pfirefox.su3 and install it using the interface on: http://localhost:7657/configplugins after installing there's a period where profiles are unpacked, configs are updated, and the proxy is checked after which you'll see a Firefox browser window open which is configured to use I2P, and a second menu in your System Tray which you can use to manage browsing sessions.

There's also a freestanding I2P Firefox profile manager that does the same thing without managing your I2P session and does not require the easy-install, https://github.com/eyedeekay/i2p.plugins.firefox.

The hard way is to create a browser.config file which can be read by the Easy-Install bundle. This file contains a list of browser names and paths to search for those names in. An example browser.config file can be found at my github: https://github.com/eyedeekay/i2p.plugins.firefox/blob/main/browser.config, by removing all irrelevant(non-Firefox, non-Windows entries) you may configure your Easy-Install bundle to use Firefox instead.

wget https://github.com/eyedeekay/i2p.plugins.firefox/releases/download/1.0.8/i2pbrowser.tar.gz

You can either use an entirely separate browser profile, like with the Easy-Install Bundle for Windows and i2p.plugins.firefox, or you can use a container tab under your main Firefox session.

Of these, Tor Browser requires the least modification, but Firefoxes can be made into a state where they are suitable for most browsing and some otherwise important purposes. That is why I favor using a profile manager which prioritizes Tor Browser and Firefox variant compatibility like https://github.com/eyedeekay/i2p.plugins.firefox

This is browser storage, and has nothing to do with I2P. I can't help you if you're using a misconfigured browser. If you are concerned about managing browser storage, I have half a dozen applications which can help you do this in a modern, portable, routine and secure way. I suggest using this one. Alternatively, This one. If you insist on doing it yourself, enjoy all the reading.

The releases of i2p.plugins.firefox are available on Github for now.

On top of that, there's almost no chance of me writing an XUL extension which can provide the level of integration that the existing WebExtensions can. I write browser extensions that write other browser extensions now, because I'm so tired of writing browser extensions. XUL was confusing before Goanna became it's own flavor of XUL. TL:DR I've got too much to do to get Goanna ready to go on my own. If somebody wants to do the research on their own and submit it to me, what I really need is a browser profile in the form of:
