Microsoft Teams (again) - teams.microsoft.com

[wapsi]

Hello,

I searched the forum and there are couple of other Microsoft Teams topics but all those threads were already locked so I decided to create a new one.

I tried to use Microsoft Teams (teams.microsoft.com) with Pale Moon v29.1.0 (64-bit, Linux) and I got it to work but only in Private Window Mode. Does anyone have a clue what could cause the Teams not to work in normal browsing mode?

To get the Teams to work I had to set network.http.useragent.global_override or general.useragent.microsoft.com / general.useragent.teams.microsoft.com to value "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:86.0) Gecko/20100101 Firefox/86.0". After that the Teams works on Private Window Mode but not in normal mode. I tried to remove all cache, settings and my profile by removing the whole ~/.moonchild productions directory to start from the scratch but the Teams still works only in Private Window Mode. In normal mode I can login but the loading stalls after that and end up with "We're sorry - we've run into an issue". Is someone able to reproduce the scenario?

I want to use the Teams in chatting mode only, no need for WebRTC (video/audio calls).

I can reproduce and I had same problem. But I also needed to do calls sometimes so I switched to using non official client, many websites don't really like webrtc implementation in Basilisk...

MS Teams exists as DEB package for Ubuntu, Debian etc, but only amd64. i386 isn't supported.

This supports more architectures (and is much faster with starting up + uses fewer resources for me). Also if you care about free software it is under GPL3 license compared to proprietary MS client.

Yeah, I know that I can use the unofficial teams-for-linux or the official Teams app by Microsoft but I was just wondering why it is not working on PaleMoon or on Basilisk but it's indeed working in Private Mode for some reason (or that's quite weird). I'm using PaleMoon and Basilisk to gain Finnish spellchecking to work on my web browser and it would be nice if I'm able to use PaleMoon or Basilisk with my Teams chatting as well. Finnish spellchecking is using legacy mozvoikko addon / extension and it is not working on Firefox anymore (at the moment Firefox or Thunderbird are not able to perform Finnish spellchecking at all which is quite sad situation: https://bugzilla.mozilla.org/show_bug.cgi?id=1403735 and https://github.com/voikko/mozvoikko/issues/5).

I checked by using the Dev Tools that Teams is not using IndexedDB in the Private Mode and thought that maybe the issues is with PaleMoon's / Basilisk's IndexedDB. And I remembered that Firefox used to have "dom.indexedDB.enabled" setting in about:config but it has been removed (see: https://bugzilla.mozilla.org/show_bug.cgi?id=1488583) and PaleMoon or Basilisk does not offer that option anymore either. So I tried to revert that commit, compile the PaleMoon (and Basilisk) and got that setting back but setting that particular preference to "false" didn't solve the issue
