Firefox 115 cannot verify addon

[TheGrave]

Today I upgraded from 114 to 115 and ka-boom:

https://ibb.co/ykx7FFh
https://ibb.co/yhGqgr8

1. Remove Tab Mix and close Firefox.
2. Open Firefox go to firefox-scripts and make sure you have the latest versions, If you need to update the files follow the instructions as if you are installing it for the first time.
3. After installing firefox-scripts close Firefox.
4. Open Firefox and download latest Tab mix.
5. install Tab mix

[TheGrave]

Firefox scripts have not been updated for years, they are installed and working. I removed TabMix and now I can no longer install it due to the same error - unsigned add-on.

[TheGrave]

After multiple tries, Firefox crashes and whatnot I managed to re-install it as a temporary add-on. Something got messed up in FF 115.

[TheGrave]

Nope, sorry, this is ongoing. Same story after re-launching Firefox. Extension can now be loaded only as a temporary add-on.

[onemen]

Firefox scripts have not been updated for years.

It was updated, this year.

Just go to firefox-scripts and follow the instruction from start.

you can try to clear your profile cache, to to about config, find your profile, and follow the link to 'Local Directory' where Firefox save your profile cache, and remove it

other option is to create new profile, if you do, make sure to install firefox-scripts files in the new profile chrome/utils

read this for more tips #159

[TheGrave]

I installed it in Jan 2023. Checked all files MD5 sums, they are good.

I'm on Ubuntu, I cleared the startup cache - made my laptop freeze a few times till I got it to run successfully. There are other issues with this version of FF too but downgrading doesn't let me in - asks me to create a new profile cause it MIGHT corrupt my bookmarks or whatever. I'll see if I can get around this bs somehow.

[TheGrave]

Noticed the following error but not sure what's causing it:

Missing chrome or resource URL: chrome://userchromejs/content/userChrome.jsm

As mentioned firefox-scripts files are as they should be. Permissions are OK, files are OK...I'm running out of ideas.

P.P. Got it, it's a cosmetic error. userChrome.jsm is included only in the package that is used for both scripts and extensions so it's non-presence shouldn't affect anything. extracted it to get rid of the error but I still cannot install the add-on except as a temporary one.

[onemen]

@TheGrave ,

I have tested Firefox beta and nightly on my ubuntu with Oracle VM VirtualBox and Tab Mix Plus work as before.

It look like firefox-scripts files was installed in your profile correctly, however the scripts that need to activate the code that allow legacy extensions to work on modern Firefox wan not installed or maybe removed when you upgraded to Firefox 115.

If you are using Firefox snap the location for the binary script changed since Firefox 108 snap.
Follow the information I have provided last year from this link

If you are using regular non-snap Firefox go to about:support look in the path from Application Binary and make sure the files:
BINARY_PATH/config.js and BINARY_PATH/defaults/pref/config-prefs.js exist and that they are up-to-date

[TheGrave]

No snap, only official repos and .js files are latest versions, correct permissions and where they should be or...see official guide:

xiaoxiaoflood/firefox-scripts#8 (comment)

Path is given as:

/usr/lib/firefox/browser/defaults/preferences/config-prefs.js

Yours renders to:

/usr/lib/firefox/defaults/pref/config-prefs.js

Which is the correct one?

I have it in both places now, still the same story.

[onemen]

the correct path is ...../firefox/defaults/pref/config-prefs.js

config.js must be in ...../firefox/config.js

when you open Firefox, check before anything else if you see any messages in the Browser console regarding the config.js file

[TheGrave]

Nope, no errors regarding the config files in either view:

https://ibb.co/pPCYYDM

[onemen]

the file config.js have to be in the same folder with firefox.exe

[onemen]

Follow this steps to identify any errors from config.js

• in about:config set browser.dom.window.dump.enabled to true
• close Firefox
• replace BINARY_PATH/config.js with this version, the file config.js have to be in the same folder with firefox.exe
• open terminal from your desktop and enter this commnad, replace the PATH_TO_BINARY with your path
  "/PATH_TO_BINARY/firefox-bin" -console > log.txt 2>&1
  this comand will start firefox and creat log.txt in your desktop folder
• report what is the content of the log file.

// skip 1st line
lockPref('xpinstall.signatures.required', false)
lockPref('extensions.install_origins.enabled', false)

try {
  dump('start config.js\n')
  const cmanifest = Cc['@mozilla.org/file/directory_service;1'].getService(Ci.nsIProperties).get('UChrm', Ci.nsIFile);
  cmanifest.append('utils');
  cmanifest.append('chrome.manifest');
  Components.manager.QueryInterface(Ci.nsIComponentRegistrar).autoRegister(cmanifest);

  const objRef = ChromeUtils.import('resource://gre/modules/addons/AddonSettings.jsm');
  const temp = Object.assign({}, Object.getOwnPropertyDescriptors(objRef.AddonSettings), {
    REQUIRE_SIGNING: { value: false }
  });
  objRef.AddonSettings = Object.defineProperties({}, temp);

  Cu.import('chrome://userchromejs/content/BootstrapLoader.jsm');
} catch (ex) {
  dump(ex)
};

try {
  Cu.import('chrome://userchromejs/content/userChrome.jsm');
} catch (ex) {
  dump(ex)
};

[TheGrave]

the file config.js have to be in the same folder with firefox.exe

I keep repeating that I'm on Ubuntu, there is no firefox.exe here :)

Here are the log contents:

`start config.js

[onemen]

I have no idea why it doesn't work for you

[117649]

@TheGrave How about run this :(await AddonManager.getAddonByID("{dc572301-7619-498c-a57d-39143191b318}")).__AddonInternal__.signedState = AddonManager.SIGNEDSTATE_NOT_REQUIRED in the browser console then clear startup cache and restart browser?

[TheGrave]

I think something is missing in this command, I get "AddonManager is not defined".

[halt76]

Doesn't work on latest version.
try this.
xiaoxiaoflood/firefox-scripts@66e896e

Run that in this console https://imgbb.com/pPCYYDM

There is only a filter field in this console. As ignorant as I am I think this is JS code that needs to be executed so definitely not the place.

This will solve the problem of not being able to validate the certificate.

[onemen]

@TheGrave ,

run this is your browser console
ChromeUtils.import('resource://gre/modules/addons/AddonSettings.jsm').AddonSettings.REQUIRE_SIGNING

If the output is false in mean your config.js work as expected and the problem is in another place. if the output is true then the problem is in config.js

report back and we continue to search for solution...

I revisited some of your previous tips and re-did the dumping in the log file. Now I got something interesting:

After reverting the files to this commit the only thing happend is my browser got screwed REAL BAD :) No tabs shown, no extensions loaded, drop-down menus can be pulled but no item can be entered.

This console

Its called browser toolbox.

[onemen]

@TheGrave

always use the browser console when debugging Firefox or extension. the console you open is the page console.

try this command again from the browser console
ChromeUtils.import('resource://gre/modules/addons/AddonSettings.jsm').AddonSettings.REQUIRE_SIGNING

[gelirhil]

don't remove cmanifest.append('chrome.manifest'); on windows 10

Nothing changed, still This add-on could not be installed because it appears to be corrupt.

I attached all my config files in current state (cmanifest.append('chrome.manifest'); was returned to config.js). I chose "only extensions" option for firefox-scripts so no userChrome.jsm for me.
config.zip

[Shahius]

@gelirhil,
Same here. Still cannot install. Same message.
Windows 10 and 117.0a1
So, I checked everything, looks correct. Tried this and that, but no luck. So, I am just coming here and hope to read something that will resolve the issue. Some clue to try. So far, I am returning back to Waterfox Classic or Basilisk browser. I cannot live without TabMixPlus.

[marty60]

TMP v1.0.0-pre.16 installed for me in 115.0 - 117.0. Try changing the config.js file to this, it's Dumby's code who manages the Custom Buttons addon

config.zip

[gelirhil]

Sorry for confusion. I believe now it was my mistake. I incorrectly placed firefox-scripts files into \profile\chrome\ instead of \profile\chrome\utils\. After fixing this TMP successfully installed and now continues to make me happy.

I'm attaching once again all my current config files. cmanifest.append('chrome.manifest'); presents in config.js
config.zip

[Brenex]

Thanks, #233 (comment) fixed it for me on OSX 13.4.1 and firefox 115.0.2

Thank you. I took files from your archive. All is working now for me too. Thank you!

[AzraelGH]

@onemen thank YOU for your work!
#233 (comment) works on 115.0.2 Win10

@marty60 and @gelirhil your Config also worked.

[Massimo-B]

I replaced the config.js file from https://raw.githubusercontent.com/xiaoxiaoflood/firefox-scripts/master/fx-folder.zip with https://github.com/xiaoxiaoflood/firefox-scripts/blob/66e896ec1514499557b64ce205104b04cdb8444a/installation-folder/config.js.

Solved the issue for www-client/firefox-bin-115.0.2 on Gentoo with installation in /opt/firefox .

[decembre]

Thanks for the config.js config.zip.

I also took files from your archive and copy them to the right place... after reading carefully your explanations.

I resume (if i don't make a mistake):

• In firefox.exe, your config.js and the "default" folder.
• I my "chrome" folder of my Firefox Profile, your "utils" folder.

AND All is working now for me too for:

115.0.3 Firefox Release
July 27, 2023

Thank you guys !
;-)

[markus88at]

Thanks a lot for all these tips in here, I managed to install TMP via the config.zip archive posted by decembre on 117.0b3 Developer Edition (it includes the config.js, config-prefs.js and %ffprofile%/chrome/utils directory).
The only problem left is that it royally screws up the context menus and the setting menu for me, which makes it kinda unusable again - any hints about that?

[onemen]

Uninstall Tab mix.
Download an install latest vesion

[markus88at]

Interesting, while I used the same XPI as before (it was the latest), it works properly now after I simply reinstalled TMP again. Could have figured myself, thanks!

[AbolfazlP9]

Hi @onemen .
I'm using the last ver. of FF.
I can't install the last ver. of TMP.
I do everything correctly, but I can't install it.

[onemen]

1. Install latest scripts to your Application Binary folder, config scripts.
2. Profile Folder is the path to create chrome folder and install utils folder in it.
3. Remove Tab mix extension.
4. got to about:config and set extensions.experiments.enabled to true
5. Open about:support and click "Clear startup cache…" to force Firefox to load userChromeJS on the next startup.
6. Start Firefox again.
7. Install Tab mix again.

[foxtom22]

1. Install latest scripts to your Application Binary folder, [config scripts](https://github.com/onemen/TabMixPlus/files/12257459/fx-folder.zip).
2. Profile Folder is the path to create chrome folder and install [utils](https://github.com/onemen/TabMixPlus/files/12257460/utils_extensions_and_scripts.zip) folder in it.
3. Remove Tab mix extension.
4. got to `about:config` and set `extensions.experiments.enabled` to `true`
5. Open about:support and click "Clear startup cache…" to force Firefox to load userChromeJS on the next startup.
6. Start Firefox again.
7. Install Tab mix again.

Not working here sadly

Thank you so much @onemen
It worked.

Almost every Firefox update I need to fix something like removing TMP extension, reinstalling all the custom JS, it's getting a lot of work to keep that addon working just for getting multi-line tabs. This time, updated to Firefox 117.0, it is not sufficient to just uninstall TMP. Again I need to check if there is any change on those custom JS. Any idea?

Script it. At least on Windows you have some workaround. Firefox Scripts hasn't been fixed for Linux for the 2+ months since I reported this bug.

Have the fixes in place before you grant permission to the update.
You can have the ff open let it install the update but don't agree to restart instead put all the fixes in place at this time then you can restart and have a seamless update.
If an add-on is disabled by ff due to scripts are failed it can not be manually re-enabled. You can only either go through the console or reinstall it.

[Massimo-B]

That means there is no patch of the scripts for Linux right now and I need to patch it manually?
Ok, again. What do I need?
I know how to script it, but I don't know where to get the patch from this time again.

It should work for linux plus you know where to put them on linux(I don't).

[TheGrave]

It doesn't. You get an empty screen Firefox and the app is unusable, been reported multiple times. Test it in a VM.

Patch it manually with what exactly? I haven't seen a working version of firefox-scripts for versions above 115 on Ubuntu and I tested all suggestions in the tickets related to this bug in both repos.

[Massimo-B]

I'm going to take a break with TMP on Linux now...
Only important features for me are multi-line tabs and Auto-reload.

I'm going to look for alternatives too. This has become too much of a burden to deal with and I'm tired of trashing a working browser on a regular basis with these scripts.
