Recently (within the last month, March 2026) when pasting links into emails on Microsoft Outlook online a pop-up window appears which prevents you from continuing typing unless you manually click on the window with your mouse cursor (hitting enter isn't sufficient). This is extremely aggravating and significantly slows down workflow. As far as I can tell, this issue only happens in Microsoft Outlook. I have ensured my Outlook settings aren't to blame, in part by failing to recreate this issue in Google Chrome and Microsoft Edge on the same account with the same Outlook settings. Here is a screen capture of this happening I recorded tonight: https://imgur.com/Qte3N6b I have ensured my Firefox is up-to-date (Version 149.0.2 64-bit). It looks like others have had similar issues. Some examples follow. 1: /u/TyDraniu reports this issue on Google Docs here: https://support.mozilla.org/en-US/questions/1567972. (I do not have this issue on Google Docs, only Outlook.) 2: A year ago a reddit user reported this issue and a config altering "fix" that a Mozilla engineer said was very bad advice: https://old.reddit.com/r/firefox/comments/1dofgd2/pasting_into_web_outlook_popping_up_little_paste/. (I have not tried this fix given the engineer's response.) 3: That reddit post links to a 2023 Mozilla Support thread noting that same "fix" but containing no actual solution: https://support.mozilla.org/mk/questions/1411533#answer-1579497.
