This is the screen I get when I follow the instructions from the first denial screen:

400. That’s an error.

The server cannot process the request because it is malformed. It should not be retried. That’s all we know.

the last time I received an email update on my desktop PC (Win 7 Pro) was 4:08PM (yes, PM) for one account and 4:44AM (yes, AM) for the other account. On my phone, the 4:08PM is the same but the other email account recd an update at 3:17PM.

As of yesterday, whenever I have to open my Firefox browser on my laptop I get the "You've launched an older version of Firefox" pop up email. I have to log in and set up all my preferences each time. I have never had to do that before.

Received Failure notice from astrologyanswers.com and support at astrologyanswers.com Can this be fixed? Was working fine until today. Joe Kil

When using any Microsoft 365 product on the browser I keep getting a prompt to "Please sign in" although I am already signed in. I can click the Sign in button and a about:blank page pops up for a split second. Then within a half hour or so, it will pop up again. I deleted my cookies but the problem still persists. Does not happen on other browsers.

Dear Firefox Team,

I’ve been a loyal Firefox user for years, and I generally love your browser. However, I recently experienced a serious issue due to how Firefox handles saved sessions, cookies, and multiple logged-in accounts.

I had two Gmail accounts saved in Firefox, both of which were at some point used to access Fiverr accounts — one active, and one previously disabled. During a session where I was logged into my active Fiverr account, my internet went down temporarily. When I refreshed Fiverr after the connection came back, Firefox reloaded a session that appeared to be linked to the disabled Fiverr account — even though I never intentionally accessed it.

As a result, Fiverr’s automated system flagged my active account for being "connected" to a banned one. This has had a direct negative impact on my freelancing career — my account was permanently flagged, and I lost access to valuable clients and my work history.

I understand that session management and cookie handling are standard browser features, but I want to highlight how important session isolation and protection from unintended auto-logins are, especially for freelancers and remote workers using platforms like Fiverr, Upwork, and others.

Please consider offering better controls or clearer separation between accounts (e.g., warning before auto-loading saved sessions, stronger isolation per Gmail/Fiverr session, or more powerful multi-account browsing containers by default).

This small technical behavior has led to a major professional loss.

Thank you for your work on this browser, and I hope you’ll take this feedback seriously to help prevent this from affecting others in the future.

Sincerely, A frustrated (but still hopeful) Firefox user

YouTube videos encoded at 60 frames per second are extremely choppy in Firefox only. Microsoft Edge plays the same videos perfectly.

I have deleted my profile and reinstalled Firefox, updated graphics driver to the latest version, and toggled hardware acceleration on and off. Nothing helps.

HI I cannot add an additional tab on top to open. I usually had no problem I need to open 6 to 8 tabs a day for work. Did firefox add a new version? every time I open an additional tab it closes the one I have open.

I don't know what happened is this a new version opened in fire fox.

Thank Linda

Hi Please could someone help me re-order my firefox toolbars. Previously I managed to arrange them in the order I prefer, but an update seems to have destroyed the order again, and I can no longer find the web page which explained how to do it. reading from the top, I would like to see: • Title bar • Menu bar • Navigation toolbar • Bookmarks toolbar • Tabs toolbar • Web content area

Instead I have • Title bar • Menu bar • Tabs toolbar • Navigation toolbar • Bookmarks toolbar (I even seem to have lost this now and don't know how to get it back!) • Web content area Thanks for any help that can be provided. Brox
