"If any of your communities use Slack, especially the “free” version, once in a while Slack seems to temporarily upgrade your “Slack team” to their “PRO” version (for 30 days).In the Slack mobile app, you may see a dismissible banner like:“PRO: Your team is on a free trial”This is your chance to go back and manually archive or follow-up on old dms and “saved” posts.If you happen to use the bookmarks (AKA “Later” or “Save for later”) feature to collect Slack posts that you want to follow-up on later, you may have noticed that any such “saved” posts older than 30 days are usually no longer viewable.When your Slack instance is on a PRO free trial, you can once again view these older posts.Use this opportunity to go through any saved posts older than 30 days (maybe older than 15 days to give yourself a buffer, or all of them to clear them out) and decide what to do with them.If there is anything about them you still want to save (for reference), copy them somewhere else accordingly, or if you saved them as a reminder to follow-up, copy them to a persistent plain text inbox, or if following-up will only take a few minutes, then take care of them.The other thing you get longer term access to are direct messages (dms).Slack PRO provides you full access to your (potentially years of) dms, instead of only the past 30 days worth. Worth checking your dms to see if there is anything you want to copy or save.I advise using the web version of Slack to do this, since it’s much easier to merely open another tab to copy/paste or otherwise take care of dms and saved posts.That’s my #WASSUP tip for the day.The IndieWeb community Slack (which itself is merely one of several ways to access the IndieWeb chat) is currently in a Slack PRO free trial, and I have been going through a few saved posts, copying content to the wiki or otherwise handling them.Glossary:IndieWeb chat  https://chat.indieweb.org/This is my eighth #WASSUP2026 post, and sixth useful web tip for September.#Slack #SlackTeam #SlackPRO #SlackTip #tip #webTipThis is post 21 of #100PostsOfIndieWeb. #100Posts #indieweb← https://tantek.com/2026/244/t1/september-blogging-challenge-wassup→ 🔮"

"Today’s #WASSUP tip: Turn on DNS over HTTPS (DoH) in your Firefox Preferences. Advanced Settings. Custom: Always use secure DNS with control over your provider and fallback behavior. [x] Always warn me if secure DNS isn’t available.There are both security and privacy reasons to use DoH.Step-by-step instructions:1. open Firefox Preferences ("Firefox" menu, "Preferences" item)2. Type “DoH” in the auto-activated search box 3. Scroll down to where it says “DNS over HTTPS” under “Privacy and Security”4. Click “Advanced Settings”5. Choose the “(•) Custom” radio button that says “Always use secure DNS with control over your provider and fallback behavior” right under it6. Check “[x] Always warn me if secure DNS isn’t available.”Privacy: the domain name of every website you browse is sent to the local router (e.g. WiFi), and on up to whatever internet service provider you’re connected to. Everything along the way has the ability to track what domains / websites you are using, how often, and build a profile accordingly, perhaps even matching it with stored profiles. The sites you use, how frequently, what time of day, may all be enough information to create a unique fingerprint of you, to uniquely identify you, and perhaps target you.By using DoH exclusively, every one of those domain names is sent only to your DoH provider (e.g. Cloudflare or NextDNS) blocking your local router, WiFi, and internet service provider from making a list of which websites you visit, or at least making it much harder (and both privacy and security are about making it harder for adversaries). They can still track what IP addresses you access, but that‘s much less information, and much less reliable over time.Security: if your local router, WiFi, or internet service provider is compromised by an attacker, they can theoretically pretend to be any website you are trying to access (DNS hijacking), and then capture your credential as you login (username, password, even 2FA), and instantly re-use them to pretend to be you (credential stuffing) and sign-in to that website. Once they do that, they usually get a "long-lived" session token (like a session cookie) that they can re-use to pretend to be you, repeatedly, until that session token expires. Some don't expire for months or even years.For example, if you’re using public WiFi, at a cafe, or a hotel, or airport, you have no idea if their routers or internet service providers are secure, and increasingly, unfortunately, we know that they are often compromised by various network attackers.We know this is actively happening from both frequent news reports:* https://news.google.com/search?q=wifi+dns+hijackAnd from Anthropic’s report published mere days ago:* https://www.anthropic.com/threat-intelligence-report-september-2026* full PDF: https://www-cdn.anthropic.com/e50be2e51e7695dc4b1366a37a245a597377d3b5/Anthropic-Detecting-and-countering-091026.pdfE.g.:  “They used compromised admin credentials to modify DNS records so that they pointed to services owned by the actor (a technique known as DNS hijacking). Guests of hotels using the compromised vendors who connected to the hotel WiFi had their traffic, device identifier and IP address sent to the actor’s servers. At that point, ClickFix-style lures were staged to deliver Windows, Android and iOS malware to the victim’s device. The actor was able to use a combination of guest information stolen from the hotel management systems with the data stolen from individual guests’ devices to focus additional targeting efforts.”  And it only gets worse from there.When you activate exclusive DoH use, Firefox skips using those local DNS services, and instead directly contacts the DoH provider for DNS queries (to connect to the websites you access).For more about how DoH works in Firefox, see the FAQs:* https://support.mozilla.org/en-US/kb/dns-over-https-doh-faqsGlossary:ClickFix  https://en.wikipedia.org/wiki/ClickFixCredential stuffing  https://en.wikipedia.org/wiki/Credential_stuffingDNS hijacking    https://en.wikipedia.org/wiki/DNS_hijackingDNS over HTTPS (DoH)  https://en.wikipedia.org/wiki/DNS_over_HTTPSReplay attack  https://en.wikipedia.org/wiki/Replay_attackThis is my seventh #WASSUP2026 post, and fifth useful web tip for September.✨ Weekly Tipster (https://tantek.com/2026/244/t1/september-blogging-challenge-wassup)#DoH #DNSoverHTTPS #Firefox #tip #webTip #browserTip #webBrowserTip #security #privacy #cyberSecurity #DNS #DNShijack #DNShijacking #hotelWifi"
