Alexey Volkov"Whoa there" yourself, Adobe. I am mildly annoyed by the phrasing that makes it look like it's my fault that a corporation can't be bothered to develop for Firefox.
ElBe@lexolf Same with MS Teams.
@ElBe_Plaq Wow, really? If it's no trouble, what part of Teams isn't working (I want to test it myself)? I understand MS's desire to move everyone to Edge (aka Chromium), but I've been using OneDrive/MS365/Teams on Firefox just fine (with the caveat of disabling some hotkeys in Firefox, which is a rare case where I think Firefox is in the wrong: Ctrl+B should be reserved for bold text on any web page, not for opening the bookmarks window of the browser).
@lexolf when I open teams.microsoft.com in Firefox it says unsupported browser. At least it used to. I can't test it now tho, will test TMRW.

That's odd: the bookmark menu should require shift as well. I use ctrl+B for bold on many web sites.

@lexolf I wonder I if that hot-key is localizable. Do you use a non -English Firefox?
@dveditz Firefox on Windows with UK English locale (but US KB layout). According to the support docs (https://support.mozilla.org/en-US/kb/keyboard-shortcuts-perform-firefox-tasks-quickly), Ctrl+B should indeed open the bookmarks sidebar, and various sites either conflict with this or handle the shortcut correctly. The Firefox developers seem to be aware of this problem, as there is a "keypress.hack" parameter in "about:config" which even contains pre-installed exceptions. I just added *.live.com and *sharepoint.com to the list and the problem was fixed.

Ah, I never use bookmark sidebar. Adding Shift brings up the "Library" window.
The full pref name is "dom.keyboardevent.keypress.hack.use_legacy_keycode_and_charcode" -- "legacy" is the key word there. Early web behavior was underspecified, and relevant to this case there were slight differences in how browsers sent key events. Around 2018 or so Firefox made changes to comply with the W3C standard. It took a while for sites to stop using "if Firefox do XXX" key handling instead of the standard, so that pref was the escape valve. Some sites to this day still only work with the legacy Firefox behavior.
It's not that Firefox is "stealing" the Ctrl+B, it's that the site didn't recognize it and then the uncaptured event fell through to the browser.
What I don't understand is how sites as popular as live.com and sharepoint.com wouldn't be in our exception list if they're getting it wrong. Do you have any customizations that might make your browser look really old to those sites?
