[okimurin]

After updating to firefox117, it became unusable.
Once I deleted TMP, I couldn't even install it.
I get an error that this add-on is broken and cannot be installed.

xiaoxiaoflood/firefox-scripts#265
I tried this and it didn't work.

[onemen]

Use these files and follow this instructions.

Firefox config and pref

utils → I'm interested in both scripts and extensions
utils → I'm only interested in extensions
utils → I'm only interested in scripts

[okimurin]

I overwrote and rebooted, but could not install.

[markus88at]

I unfortunately have to second this, the update 117.0b3 fully broke it, even in the Developer Edition which I was using.

[onemen]

You need to unistall Tab mix
Install the config script https://github.com/onemen/TabMixPlus/files/12257459/fx-folder.zip

And install utils files from above

Donload an install Tab mix

[okimurin]

I overwrote the "utils" file in the Chrome folder in the profile folder, overwrote the contents of "fx-folder" in the installation folder, and restarted, but I could not install it.

[okimurin]

When I placed the "Config.zip" file posted by Mr. gelirhil in thread #233, I was able to install it successfully. TNX!

[DoulosTrieste]

I pasted the config from #233 but still could not install TMP on 117 Release.
Everything else already setup as per instructions from UserChromeJS.

In addition to this:

You need to unistall Tab mix Install the config script https://github.com/onemen/TabMixPlus/files/12257459/fx-folder.zip

And install utils files from above

Donload an install Tab mix

to me (running Arch Linux on PC and Laptop) helped also the following after Utils were updated:
"Open about:support and click "Clear startup cache…" to force Firefox to load userChromeJS on the next startup."

[denmorgenshtern]

I've encountered the problem "This add-on could not be installed because it appears to be corrupt."
Reinstalling the add-on did not work.
Deleting it did not help either.
Reinstalling all associated scripts and the "115 update" configuration did not work either.

The issue was only resolved when I deleted the old associated files in all profiles (I have 2) folders and the application folder, and replaced them with new ones (although it seems that they are the same). With "Clear startup cache" of course.

[DoulosTrieste]

This worked in Firefox 117.

#233 (comment)
https://github.com/onemen/TabMixPlus/files/12061991/config.zip

Don't hunt for assorted zips all over the place, just use this config.zip

[VLM-TechEd]

[DoulosTrieste] Those are old files, are they not? And at this point, what version of TMP are we supposed to be installing? I have 117 (downloaded a while ago), but on the downloads/releases page it looks like 116 is the most recent version. I am confused.

[onemen]

latest Tab mix is v1.0.0-pre.16

latest Firefox is version 117

[VLM-TechEd]

Thank you. Still confused about what else to do; there appears to be no conclusion to this thread.

install the latest scripts

Use the newest TMP dev version.
Apologies, for the zip file I posted, the config.js is the most recent. The rest are not.
As for the Chrome\Util files, what worked for me was using Multirow-Patcher-Quantum-Nox-Installer-Windows-1.8.13, because I also want tabs-below-navbar. So I really only needed to replace config.js directly.

Use the links that TMP dev has provided, you won't go wrong with them. Delete all older files first (chrome\utils folder, config,js, defaults\pref\config-pref.js), then paste the new ones in.

[VLM-TechEd]

“Add-on could not be installed because it appears to be corrupt” until I remembered to clear cache and restart Fx. Now, everything works fine again. Thank you! [DoulosTrieste], thank you, too!

[VLM-TechEd]

Oops, now the problem of the dialog running off the screen with high zoom again. You made a pre pre-pre-release version 17 for me which solved the problem. But I didn’t save it because I assumed it would be absorbed into a future release. The future release just hasn’t arrived yet.

[dxzy]

open my PC, autoupdate to 117, TMP dead too.
After trying many times, userChromeJS cannot be started, so the TMP installation is always broken.

I don’t know why utils and config.js are always invalid.
I gave up, tried everything above but still failed, beyond my capabilities.

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. Open about:support and click "Clear startup cache…" to force Firefox to load userChromeJS on the next startup.
5. Start Firefox again.
6. Install Tab mix again.

[dxzy]

1. 將最新的腳本安裝到您​​的應用程序二進製文件夾， [配置腳本 ](https://github.com/onemen/TabMixPlus/files/12257459/fx-folder.zip)。
2. Profile文件夾是創建chrome文件夾並 [安裝utils文件夾的路徑。 ](https://github.com/onemen/TabMixPlus/files/12257460/utils_extensions_and_scripts.zip)在其中
3. 刪除選項卡混合擴展。
4. 打開 about:support 並單擊“清除啟動緩存...”以強制 Firefox 在下次啟動時加載 userChromeJS。
5. 再次啟動火狐瀏覽器。
6. 再次安裝 Tab mix。

Same steps, but it worked this time. Still not sure why, thank you.

[Vallek]

Make sure ''extensions.experiments.enabled' is enabled in about:config! Firefox 117 turned it off for me.

[VLM-TechEd]

> Make sure ''extensions.experiments.enabled' is enabled in about:config! Firefox 117 turned it off for me.

Good point, thank you!

[VLM-TechEd]

latest test build is here: https://tabmixplus.org/dev-builds/test%20builds/ Works perfectly, as before. Thank you!

[Brenex]

Thanks, re-enabling extensions.experiments.enabled (grrr) and then #235 (comment) fixed it for me on 117.

[spartaque12]

this is such a nonsense ive tried half of day, and still cannot figure out why i cannot install extension, it always says
this addon could not be installed because it appears to be corrupt
of course i did in about:config
xpinstall.signatures.required = false
extensions.experiments.enabled = true

This is probably a stupid question, but in step 2, did you put the files in a folder named "chrome" inside your profile folder? I missed that part a few times before I realized it and now it works like a charm!

Thank you so much for this one !

nah, it used to work, but now i cannot make it work. I just dont understand why extension cannot be installed, it always says me that it's corrupt

[lonegungirl]

I kept getting a message that it wouldn't install the extension because it was corrupt, but then I repeated all the steps and now the message says that Firefox won't install the extension because it's unvalidated.

[onemen]

try this:
go to about:config and set extensions.experiments.enabled to true

[lonegungirl]

Ugh, extensions.experiments.enabled is still set to true from when it was working before this last update yesterday.

[VLM-TechEd]

Lonegungirl, when you finished setting things up, did you remember to clear cache? That did it for me.

[lonegungirl]

Yeah, cleared startup and all other caches I could find, but still nothing. I tried installing Nightly to see if I could switch to that, but having run through all the instructions for that, I get the corrupt popup on that one, and the unvalidated popup on regular Firefox.

[Ramel]

It seems we need to install: utils_extensions_and_scripts.zip

utils → I'm interested in both scripts and extensions

I've been on the problem for two days with no solutions.
