If you’re getting an '''NS_ERROR_DOM_ABORT_ERR''' while trying to open web.telegram.org or app.slack.com on Firefox 87, or if these pages aren’t loading at all, here’s a workaround you can try:
#Enter '''about:serviceworkers''' in the address bar.
#Click {button Unregister} for the site you’re trying to visit.
#Reload the site.
#If the site still isn’t loading properly, clear the storage for that site (see [[Clear cookies and site data in Firefox#w_clear-cookies-for-any-website Clear cookies and site data]] for #more information.)
