This extension works on Firefox

[haxibami]

Procedure (after installation)

Note: I tested this with OldTweetDeckFirefox.zip v1, generated by npm run build.

Note2: This procedure is for v1, not v2

1. Grant permissions manually

In the current implementation of Manifest V3, Firefox treats some permissions listed in host_permissions as "optional". So users need to manually grant them from "about:addons > Extensions > Old TweetDeck > Manage > Permissions".

2. Disable tracking protection

Also, Firefox's "Enhanced Tracking Protection" prevents <iframe> elements (inserted by this extension) from loading correctly. You can add exception for TweetDeck.

How were you able to install it?

[haxibami]

The author provides a build script (pack.js) for Firefox. You can run it to generate a patched .zip file.

git clone https://github.com/dimdenGD/OldTweetDeck.git
cd OldTweetDeck
npm install
npm run build
mv ../OldTweetDeckFirefox.zip ./

You should then find OldTweetDeckFirefox.zip. Try temporary installation (unsigned) or self-distribution (signed), as you wish.

Thank you!

[archeruwu]

Heads up!

You will need Firefox Developer or Nightly to add unsigned extensions.

When I try to run the pack.js file I get this error

The pack.js file seems to be running as JScript, not JavaScript. How did you run it? do you have Node.js installed?

I double clicked on the file in the folder and it gave that error. I have installed Node.js and attempted to run the script with it but it opens for a split second and then closes after doing seemingly nothing.

[dimdenGD]

check parent folder of folder it's in, archives probably appeared in it

[Koraydi]

I managed to catch it with a screen recorder

[dimdenGD]

run npm install in the folder

I've built extension and made a Release, check https://github.com/dimdenGD/OldTweetDeck/releases/tag/v1.0.2

Sorry, I feel stupid, but I can't understand how to "add" the zip into firefox :s. When I try to load it (using developer version or my normal version) I get an error.
I downloaded the zip version in the BetterTweetdeck fork page.

Nevermind, found it:

• First, install Firefox developer
• Disable signed extension in about:config : xpinstall.signatures.required set on false
• Load the extension in about:addons

[PRGilland]

When I install it on Firefox Nightly, I get this when I reload the tab, even though I'm still logged in when I get redirected:

[Mara-Li]

I need to refresh a lot to get it works, on my side!

[archeruwu]

If you get the login error, or it just doesn't load, refresh a few times.

[PRGilland]

I don't know how many "a few" is, but it's still not working. If this is something that has to be done every new session, It's probably not worth it for the time being

[archeruwu]

Any way of getting legacy back is still better than dealing with "XPro" to be honest.

[LisandraBrave]

manifest.json lacks an add-on ID in "browser_specific_settings", meaning it will only install through about:debugging on firefox (even on nightly and developer), and won't install permanently.
However, reportedly chrome doesn't support the "browser_specific_settings" key and will show a warning if it's included. One possible solution is separate manifest.json per platform

[dimdenGD]

This is already done in pack.js

[LisandraBrave]

So it is. Must be some issue on my machine causing it then

[dimdenGD]

You can only install unsigned extensions on Firefox Beta/Nightly

[LisandraBrave]

Does it not work on developer (which lists being on aurora update channel)?
Edit: It does, after restarting with all add-ons disabled, installing, and then re-starting, for some reason

[archeruwu]

Anyone else getting near unusable lag after leaving the tab open for an extended amount of time? (Firefox Dev Edition)

[Fapo39]

still doesn't work for Firefox Nightly or ERS even with v2.02 while it works just fine for Chrome

[haxibami]

In my case, v2 does not work on Firefox. <script> elements injected by element.innerHTML in injection.js are blocked by content security policy (CSP).

So I tried loading these scripts (bundle.js, vendor.js) as external files (element.src) - this time, they load fine, but the use of eval() in them violates CSP.

In any case, Content-Security-Policy header does not seem to be removed, despite the existence of the relevant code.

[haxibami]

OK. Found the cause:

In Firefox, extraInfoSpec in browser.webRequest.onHeadersReceived.addListener only allows the values "blocking" or "responseHeaders" (or both) ,while in Chrome "extraHeaders" is also supported.

So we need some switching like this:

Thanks, I've updated repo and released new version

[Dajova]

Sorry for bringing this up, but it either seems broken again or it was just temporarily.

All i get is this (stuck on this page), even after clearing cookies, reinstalling the extension several times and refreshing the page once a minute for almost a hour. It worked the first time, but not once since then.

edit: nwm, it worked once i removed the login part of the url.

You can only install unsigned extensions on Firefox Beta/Nightly

You can install it on main firefox as a "temporary extension" in about:debugging > This Firefox.
It'll uninstall upon closing but it's still an alternative for main fox.
