Because it is built on Chromium, Opera supports Chrome extensions, so the transition away from Google should be a smooth one.

20 Telegram Alternatives to Chat With in 2024
Slack works more like a forum than Teams does – falling somewhere in between a forum and a chat software. It lets you organize discussions into different channels, as well as by thread. You can invite others into a thread by @mentioning them, and it lets you add lots of different types of content. Slack works really well for 1:1 audio meetings, “huddles,” that give you the...
Why we switched to Mattermost
Now, obviously core messaging functionality is critical. Mattermost is great there, but so is Slack. In fact, Slack features like third-party integrations and threaded messaging were missed greatly (thank you, Mattermost, for recently adding threaded messaging). So the relative parity between the solutions from a ‘speeds and feeds’ perspective was table stakes, but we...

Microsoft Teams Vs Clariti: Which one should you choose?
The main reason behind the sudden rise of Teams is it is being offered at no added cost to Office 365 users. This strategy paid for Teams as it was able to increase its market share and overtake its potential rival Slack in no time. Though Microsoft is not earning any revenue (they may actually be losing money in selling Teams), they are able to sustain due to their deep...

  • Can anyone tell what is this?
    This is not opera.com it's "api2 dot com" so it's a malware site posing as an opera one by including opera in its name. I had a popup like this. It opened every time I opened the browser. Turned out it was coming from a video downloader extension. Source: 11 months ago
  • Is there a way to download the official browser through a torrent or a mirror link?
    The opera.com domain is banned where I live but I still want to download the browser without a VPN (because those are also banned). Is there a torrent link or an alternative/mirror link where I can download the latest Opera One release? Thanks! Source: 12 months ago
  • Opera Adblocker pinging opera.com?
    Apparently it "urgently needed to be removed off the network" (bullshit, you could've blocked opera.com, dumbass) I don't see why its so bad to have one kid with an unmanaged browser, like seeing "your browser is managed by your organisation" sucks enough. They disabled basically everything good about Chrome, for a time, they locked down the performance tab so we couldn't even use battery saver. Source: 12 months ago
  • Opera Adblocker pinging opera.com?
    One day, I got called to my Deputy Principal's (Dep. For short) office because my laptop was doing wacky shit to the network. He informs me that my laptop had sent 64k pings to opera.com. It was about the 2nd term, we receive new laptops every couple of years. He first told me about my searches for a VPN, which I guess is on me. But when he brings up the 64k pings, he tells me whatever the app is doing it has to... Source: 12 months ago
  • How big is the chance of getting malware while downloading roms?
    I use uBlock Origin on Chrome but it is available for Opera GX as well. You install it by finding uBlock Origin in addons section of opera.com and then clicking the "Add to Opera" button. Source: about 1 year ago
