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 – Ehsan, Freelancer
