My favorite Firefox extension, Too Many Tabs, just shit the bed

i've never used such an extension, but a brief search brought up https://addons.mozilla.org/en-US/firefox/addon/onetab/ which sounds like it performs a similar function

I've tried it but It's not as good

well, it's not really a solution but you could always just downgrade to the most recent version of firefox the original extension works with and stop updating. of course other stuff will eventually stop working because of it, but that's a problem for future you to deal with!

Session manager?

it's called bookmarks and it's been built into all browsers since like 1993 you bitch

I'm seriously thinking about that

>it's called IE it's been around since 1995

This is what you sound like, faggot

You need to get the source code and modify the install.rtf file. Search for the extension on googled followed by github. download the ZIP file, modify, build the .xpi

Modify to do what?
