Hello,

please note that Twitch only supports two latest version of Firefox (138 and 137 as for now), while you use a much older version (115). According to this Reddit thread, the following may help:

1. Clear Twitch cookies and data, see the first section of Clear cookies and site data in Firefox for details.
2. Enable (set to true) layout.css.has-selector.enabled Firefox preference in the Configuration Editor. For details about how to open and use the Configuration Editor, see Configuration Editor for Firefox.

All layout.css in the long list in Configuration Editor for Firefox that have false must turn to true or someone spesific?

I inform you that I had no issues qith Mozzila 115.18.

All layout.css in the long list in Configuration Editor for Firefox that have false must turn to true or someone spesific?

layout.css.has-selector.enabled (only this single preference, named exactly as stated above)

Please note, however, that despite fixing the problem with Twitch, enabling this preference may cause some issues with other sites. At the current moment, Firefox developers in contact with their Twitch colleagues are working on a solution.

Then I will wait for your solution rather to mess up my beloved Mozzila. I wrote to them (Twich) to contact you and they told me that since my Mozzila version (155.x) is in their supporeted brawsers the issue was only mine but chating in Twich streamings there are many people waiting that solution. Thank you for your petience and willing to solve the issue. With regards AnthoniusII

Out of curiocity in the Configuration Editor / layout.css The last sentence is like this without my interfearence. In Greek the worlds are Truthfuness , arithmitic , alpharithitic . It allows me to change to True /False but i want to be sure that i do not make anything that would compromise your efforts for solution. Should that be like this by default?

AnthoniusII,

it prompts you to create a new preference as there is no default one with input name. Please do NOT do that. If you want to try the suggested solution, search for (COPY that from my message) layout.css.has-selector.enabled and toggle ONLY this preference.

I'm attaching a screenshot with an illustration. Note: the default value of this preference in my browser (version 138) is true, but in yours it will be false.

I made no changes my self . That what is in my picture was as such when i open the configuration file . I did not tuch anything. So to avoid to bother you more i will wait your expirient team's final solution to avoid messing up with things i do not understand. Thank you again for you petience and kindness to reply. I will check regularly this topic untill you will write that the next Mozzila version includes the solution. Thank you again my friend.

Hi Anthoniusll,

You're making a great judgement call by not toggling that pref if you're not feeling comfortable. This issue occurs because Twitch recently started using a web feature that Firefox 115 and other older browsers don't support.

That said, our team is alrready in contact with the Twitch engineers, and they're actively looking into it. Here's a link to the bugzilla report for this issue if you want to follow the progress. We'll make sure to update this thread when the fix is ready, though.

Thank you again for your willing to solve this issue. I will wait your expirient and finall solution by you the experts . I am an old guy that has no knowlege in similar issues. I will wait. THANK YOU AGAIN.

When i 1st reported to Twich that issue they guided me to use a Mozzila command and take as many screenshots of the log and errors that would apear but they informed me that they "ignored" my answer. All those screenshots included in this .rar pack . I hope they will be usefull for you. Many people that still refuse to leave Firefox for Chrome are waiting your solution. link text

Hello AnthoniusII,

It should be fixed now, as Twitch has reverted their change that triggered the issue.

Thank you for your patience!
