Since today Tab Mix Plus could not be verified for use in Firefox and has been disabled

[lgander]

I've been happily using TMP for many months.
A couple of times it stopped working and had to reinstall, but today no matter what I do it's still not verified/working.

Firefox 115.0b2
Windows 11
tab_mix_plus-dev-build v1.0.0-pre.15

Any ideas?

download and install this test build
https://tabmixplus.org/dev-builds/test%20builds/1.0.0-pre.16.20230607.1.xpi

Thanks for the quick reply.
I still got this when trying to install it

check in https://github.com/xiaoxiaoflood/firefox-scripts#instructions, that you have the latest version of all files
also you may have to:

• uninstall Tab mix
• close Firefox
• start Firefox
• install new Tab mix version

I've tried downloading both zips and replacing the files.
I've also tried that uninstall-restart-reinstall process.
I still got the same error.

I really don't know what else can I try. Do you have any other ideas?

Thanks again!

I've read and tried everything.

I also created a new profile, copied de utils folder inside a "chrome" folder I created inside the profile folder. Same error trying to install the xpi.

Let me copy some screenshots just in case.

I'm on windows 11. I'm using XYplorer, that why the explorer looks different.

It was working for long months, so not sure what could change.
Do you have any other idea? Is there any way to try downgrading FF maybe?

Thanks again!

Try set in about:config xpinstall.whitelist.required to false, for some cases it may help.

Still doesnt work.
This is a screenshot of my other xpinstall in case you see something wrong there:

Thanks a lot for taking the time to help me!
