I use Firefox as my primary browser (version 84 as of today). As part of this, I keep logged into a number of slack channels. These are some of my favorite communities and I go there to chat with folks, learn about interesting topics and hunt for neat links to resources I didn’t know about. Occasionally I’ll even ask a question or two.<\/p>\n
Recently, I saw some weird behavior. The slack channels weren’t updating. The notice at the bottom of the browser bar was something like “Slack is trying to connect”.<\/p>\n
Hmm, I thought, that’s weird. I tried reloading the page. I couldn’t do it. That is, even hitting control-f5 didn’t change anything. However, I could open other website just fine.<\/p>\n
I tried quitting all my browser tabs and restarting. Made sure Firefox was up to date. Checked the Slack status page to see if slack was down. Opened a new tab and typed the slack channel url into the address bar.<\/p>\n
Nothing.<\/p>\n
So, I popped open the dev tools and looked at the network tab. I saw this error when loading app.slack.com:<\/p>\n
NS_ERROR_DOM_ABORT_ERR<\/pre>\nThat turned up this bug<\/a>. From a scan, several other folks where having this issue, with slack and other sites. This comment<\/a> shared the solution:<\/p>\n
Clearing storage for app.slack.com fixed the issue, and the Slack workspace loads correctly now.<\/p><\/blockquote>\n
