ERROR: "Bad Request - Request Too Long" When Signing In To Microsoft 365 Using Work Profiles
When the following conditions are true: Using the latest version of Microsoft Edge browser. When the browser is signed in to any Microsoft 365 account. When browsing to any Microsoft 365 website. I receive the following browser error: Bad Request - Request Too Long HTTP Error 400. The size of the request headers is too long. When I sign in to any Work Profile, no matter the account/tenant, the moment I browse to any Microsoft 365 page i.e. any website that redirects via: https://login.microsoftonline.com/, I receive the error above e.g. https://office.com, https://admin.microsoft.com, https://portal.azure.com etc. If I sign-out from the Work Profile, everything works fine (i.e. I am presented with the usual Microsoft 365 sign-in dialogue for username and password, then 2FA code, then the expected page appears), if I then sign-in > browse > error ... sign-out, works fine, sign-in, error etc. ... consistently repeatable. Using 'Browse as Guest' or any 'Personal' or 'Work Profile' without signing in works fine. TROUBLESHOOTING ALREADY CARRIED OUT Deleted/recreated all profiles. Signed in / out multiple accounts on multiple tenants. Sync options > all, some, none. 'Automatic sign in on Microsoft Edge' enabled & disabled. 'Allow single sign-on for work or school sites using this profile' enabled & disabled. 'Automatic profile switching' all options on & all off. Deleted all cache/cookies, from all time in all profiles. Reset settings in all profiles. Completely uninstalled/reinstalled Microsoft Edge (i.e. Safe Mode > delete all files > all profile data> all temp files > all registry entries). Q1 What could cause this error, only when the Work Profile is signed-in? Q2 Aside from syncing settings, how would signing-in to the Work Profile effect OATH requests to https://login.microsoftonline.com/? Q3 Has anybody experienced this or something like this before? Q4 Are there any troubleshooting steps I haven't tried?
Edge and full screen bug on Mac
I try to investigate full screen bug on Mac for many days about invisible click wall at top of screen. Today, I turn off hiding menu bar. Then when I use Edge in full screen there are strange area at top of screen. It seem that the height is similar to the invisible wall. And Bing button and Sidebar is disable at full screen mode, too. I try to use Edge as my main browser but these bug make me stay away. I research and found that many people talk about this bug (full screen and sidebar) for a long time. But no action or clear answer from the team. I hope the team will see this post and fix these bugs. Thanks,
Pinch Zoom Behavior Changed in Edge After Update – Need Help!
Hi everyone, I updated my Edge browser yesterday, and I've noticed a change with the pinch and zoom functionality on my laptop’s trackpad. Previously, I could pinch and zoom without affecting the page’s Zoom %—the percentage would only increase if I pressed Ctrl + pinch and zoom. However, after the update, simply pinching and zooming now increases the page’s Zoom %. This behavior doesn’t occur in Chrome, so it seems to be isolated to Edge after the recent update. Has anyone else experienced this issue? Any advice on how to restore the previous behavior? Thanks in advance for your help!Missing acrylic/mica effects in all builds
In the recent Dev/Canary branches I noticed that the mica and acrylic effects were removed even with the flag "Show Windows 11 visual effects in browser" enabled, but this has now found its way into the Stable channel and there are no more transparency (mica/acrylic) effects in the browser at all, including in menu dropdowns. Is this expected or a bug?
Please Provide Option to Disable "Ask Copilot" in Address Bar
I use Kagi as my default search engine. Recently, I've noticed that if the search string reaches a certain length, the default search option changes from Kagi to "Ask Copilot." See the image below. This is driving me insane! I don't necessarily mind the "Ask Copilot" feature but having it automatically selected when the search string reaches a certain length is unbearable. Please, at least provide an option to turn this behavior off. This is so annoying that I have had to stop searching from the address bar and navigate to the Kagi website for each search.
The official place to report bugs
I am a user of the beta version of Edge on Linux. From time to time, I encounter bugs that I’d like to report. After some searching, this forum is the closest I have found to a bug tracker. So I was wondering whether there’s a dedicated place for reporting bugs or should I just post here?
