Dreaded "Addon is corrupt" error

[hydroculator]

I have been unable to install the addon, and receive the "addon is corrupt" message. I have read and followed every instruction and suggestion I can find in all the threads under Issues and the install instructions multiple times. I've manually verified all the advanced preferences items, I've cleared the startup cache. I've tried every version of config.js I have seen in all the threads. I've tried running the code in the browser console. I don't know what else to try. I deleted the cache folder in AppData\Local.
I've gotten this to work on my personal computer, but this one is managed by IT. I have admin rights on it, but could there be something else that I could check to see if something is overriding this somehow?

Thanks for your help and the great addon.

What is yor firefox version?

[hydroculator]

123.0.1 (64-bit)

[onemen]

you only see the "Addon is corrupt" message if the scripts that allows legacy extensions to work on Firefox did not installed properly.

follow ALL installation instructions

if you are using Fifeofox 123 it is better no to use old profiles (default-esr),

I also had difficulties with the new documentation and even repeating all the steps several times, I continued to receive the message that the "addon is corrupt". I decided to redo the steps, but instead of using the documentation files, I used the backup files from an installation that I used until last week and it worked the first time. I used the "test-build-1.0.0-pre.19.20240309.1.xpi" version and updated the extensions, updating the TMP to the latest version, 1.19.1.

This backup used the "old" method, which used userChromeJS

I'm using Firefox Nightly 125.0a1 (2024-03-11) (64-bit)

I would like to understand why it worked one way and not another.

[onemen]

@ozzyjr,

can you provide copy of the script files you where using.

what is your operating system?

[ozzyjr]

Of course @onemen

I'm on a MacOs Sonoma 14.4

Files files.zip

[onemen]

@ozzyjr,

I will try to check these files and the files from the dcos and see if I can reproduce this issue.

beside the different files is there anything else that i can do to improve the installation documents ?

[ozzyjr]

@onemen

No, the installation documents are fine. The only problem was the corrupt addon message that I couldn't resolve using the documentation files.

Other than that, your service is as excellent as ever.

[onemen]

@ozzyjr ,

I have just tested the files from installation documents on my VirtualBox MacOS and I was able to install Tab Mix Plus without any problem.

One important different between utils zip file in the documents and the files you are using is that in you zip files utils folder is inside chrome folder and the documents utils folder is at the root of the zip file.

I just updated the instruction

[ozzyjr]

@onemen

OK. Thanks for the explanation and help.

Same problem on windows, installed everything correctly, like always, but this time the corrupt message shows up. Upgraded firefox to 124.0.1 and these problems began.

edit: Forgot to uninstall Tab Mix Plus AND restart firefox before installing it. Now it works. The install doc was missing that so I almost forgot.

Same issue here on Firefox 125.0.2 (64-bit), Windows 10. Did not have TabMixPlus installed before.

Should I change general.config.obscure_value from 13 to 0?

we already have pref("general.config.obscure_value", 0); in the file config-prefs.js - that should be copied to [PATH TO FIREFOX.EXE]/defaults/pref, if the value for "general.config.obscure_value" is 13 that is indication that you did not install Firefox Scripts properly.

[koppor]

Thank you so much for the support! Yes, that's it! TerraCopy worked only the second time when copying.

[Squall-Leonhart]

I have this occuring here too, just not for TMP, but other extensions such as bbCodeWebEx and enhanced-h264ify,

issue is directly caused with the placing of the config.js in the installer folder as removing it and restarting it allows them to install again.

[onemen]

Verify that all your firefox-scripts are up-to-date https://github.com/onemen/TabMixPlus/files/14075743/fx-folder.zip https://github.com/onemen/TabMixPlus/files/14075742/utils_extensions_and_scripts.zip

[Squall-Leonhart]

They certainly are, i only just downloaded them (from here)

I can reproduce it reliably on Waterfox G6 and Firefox whateverthehecklatest is, its just the two mentioned extensions though, i assume something to do with their signing or something, i can install most others fine.

[onemen]

@Squall-Leonhart read #292

[Albirew]

for the record, some installations (like mine) have a defaults/pref/antibeacon.js file containing pref("general.config.filename", "mozilla.cfg"); and pref("general.config.obscure_value", 0);.

In this case, I added at the end of this file pref('general.config.sandbox_enabled', false);, and pasted all content of config.js into already existing mozilla.cfg (witch was containing a bunch of security-related lockPref)
