Out of curiosity why would you be using such an out of date browser?

Browser usage is quite uncomfortable without xul-extensions.

I restored the older version of tt-rss from backup. Problem solved.

I know a fair amount of people switched to the pale moon browser to keep somewhat up-to date and have xul extensions. Perhaps you should look into that?

Thank you, I know about this browser.
Only few persons develops it. It does not inspire confidence in the future of this project. Maybe someday I will try this browser.
I think this is offtopic

Wow, a really bad surprise after update. Is there a chance to fix this without updating the browser?
ps, please, add message to the commit about future critical changes, thx

tt-rss software requirements are stated on tt-rss.org frontpage. i’m fairly certain that whatever ancient shitware you’re using - by your own choice - instead of a web browser is not listed there. at least you get to enjoy your unpatched CVEs while everyone leaves you behind.

also, you get to enjoy your permanent ban. fuck off of my forum and don’t come back, luddite.
