Extensions not working
Asked by Russ Kulas:

Just now[,](https://rapidhms.com/) three extensions that I rely on every day stopped working. (They are: Collapsible Trello Lists, Trellists: Trello Lists Master, and List Highlighter for Trello.)  

Is anyone else having a problem with extensions??

body: From Trello Support Team about a week ago...

We recently released some changes to Trello's backend, which have resulted in significant improvements in performance, accessibility, and usability for our users. However, these changes have also had an impact on how certain third-party browser extensions work and interact with Trello. We have already reached out to the developers of these extensions to notify them of the changes and provide guidance on how they can make adjustments to ensure their extensions work well with Trello.

In case you're facing any issues with a browser extension, we recommend reaching out to the extension's developer directly. They should be able to provide you with further support.

body: Hey Team

Has anyone else lost their list high lighter? I've updated my Chrome version and cleared cache and restarted my PC without any luck. Any suggestions? Anyone else lost it?


author: Mel McMurrin
body: Yes! See my note below. Fix coming.


author: Danni Coyote
body: I contacted the developer and he responded that he is currently working on a fix for List Highlighter. He also linked me to his [blog with some updates about the new version.](https://beingmrkenny.co.uk/web-extensions/list-highlighter-trello/version-5)

Hope this helps!

body: Thank you!!


author: Austin
body: Great news! Thanks [@Danni Coyote](/t5/user/viewprofilepage/user-id/5346812)


author: David Plummer
body: Thank you to everyone involved.


author: jamie erskine
body: do others have it working now? I see on the blog the developer has updated it, but my extension still doesnt work and the extension says last update june.


author: Ytzen Lont
body: I used Trellist (hiding/showing lists).  
It has not come back (yet).   

As an alternative I'm using Collapsible Trello Lists now.   
Not the same (must collaps/expand each list by hand), but second best.


author: Ytzen Lont
body: Same here. Chrome extension Trellists is essential for me, but does not work anymore.


author: Mel McMurrin
body: FYI Jan 23 2024 List Highlighter stopped working. Mark the developer is aware. Here is what he wrote back:  

*Thanks for your email again! I've looked into this and it seems Trello has made a small change to their system, but it should be a simple fix :)*  
*I hope to have something out before the weekend. If you're on Chrome it usually takes a few weeks for their approval process to complete, but other browsers are usually quicker.*  
*Kind regards,*  
*Mark*   
Not sure what else yesterday's change made to other extensions...

comments: author: St?phane Franceschini
body: Thanks for the update!

Such a simple feature, I wish Trello would buy out the code from Mark and implement it natively...

Thanks to the dev again :)


author: Mel McMurrin
body: At last, I can breath again. Version 5 is now working on Chrome (after clearing cache.) Thanks to the developer Mark Kenny for saving us. I've just bought him some coffee via Paypal: beingmrkenny@gmail.com. Consider it, fellow List Highlighter addicts...

comments: author: Malin Hunter
body: Thank you Mel for posting this. Mine wasn't working but it is now after deleting the cache and updating my Chrome version.

It's a happy sight getting the old board look back.

I'm not sure how to buy Mark coffee from NZ but I'll send him my thanks in an e-mail.

Cheers


author: Mel McMurrin
body: Yes, I want to look at my board(s) again!  
BTW that was a virtual coffee (a few GB pounds and a thank you) from the States to his his PayPal address (which should work in NZ.) I told him he should put a donation button on his page somewhere!  

Gotta run, my red list is calling me! It's grown some over this month of greyness...

author: St?phane Franceschini
body: Still working on Edge.  

For Chrome I tried:  

- Uninstall all Chrome apps, only keep List Highlighter  
- Clear history all time (cache, cookies, browsing history...)  

Still not working.  

I don't know what you guys think but it really seems like a "Chrome new update" kind of problem rather than a "trello" or a "list highlighter" problem.  

The only one that can fix that is the app dev now.  

Please, if you read that, your app is awesome, help us ??


author: Mel McMurrin
body: List Highlighter stopped working for me a week or so ago (Chrome Version 118.0.5993.89.)  
Still works on Edge Version 118.0.2088.61.  
I do have a lot more plugins installed with Chrome (which I've disabled to no avail.)  

UPDATE: after a day or so Edge plugin stopped working too...


author: Danni Coyote
body: List Highlighter suddenly stopped working for me just now. I am looking for solutions, as I rely on this extension daily. Has anyone found a solution yet?


author: K T
body: Yes, multiple extensions not working for me. Atlassian are you going to make a communication about it at all? Is it Trello? Chrome? ? Do you have solutions?


author: Alexandre Blain
body: Yep, my List Highlighter for Trello has just stopped working as of today.


author: St?phane Franceschini
body: Same for me, I really hope the person behind [List Highlighter](https://beingmrkenny.co.uk/web-extensions/list-highlighter-trello) is already on it and there is a fix.  
Or at least that Trello has planned to include this life-saving feature as native... ??


author: Marc Lamblin
body: Same here with

Collapsible Trello Lists {#toc-hId--414296177}
----------------------------------------------


author: Maciej Biega?ski
body: Same here. Why it doesn't work anymore after update?


author: Serge Souprano
body: Same here, not working. Was it an update to Trello, Chrome OR the plugin?


author: Tuan-Anh BUI
body: Strangely the list highlighter still works with the account I created using company email (new one, created just 2 days ago). None of the personal accounts worked.


author: Malin Hunter
body: Yes list highlighter stopped working. Looks like there have been updates as we also get a black line around the card.

I'm also having issues with Trello freezing up,


author: Martin Norbury
body: Yes, my List Highlighter for Trello has just stopped working too.
