Thanks a lot for making this! It helps a ton on Linux.

Very useful addon, I don't understand why Firefox don't use it by default.

Absolutely superb add-on. Does precisely what it says it does and no more. Requires zero permissions.

As others say, it just works. This firefox extension perfectly solved my annoyance of needing to use Alt+Number to change tabs after changing to linux from windows. thank you devs.

it just works

works as intended, without issue

does exactly what it says it does :p

Used this since Firefox does not use Ctrl but Alt on my laptop using Linux Mint.
Now both work, perferct!

Thank you for this, it's super helpful for my productivity!

Alt is already my Window Manager mod key. Thanks for the extension!
