A recently added computer's Firefox is not available on the "Send Tab To Device" list.

Both computers are logged into my Firefox account and Firefox is syncing. The new computer populated with my extensions and other synced data. The new computer shows the old computer in it's Send Tab list, but the old computer does not have the new computer's Firefox name in the Send Tab list.

On both computers, I can go to the menu / Manage Account and see the list "Connected Services - Everything you are using and signed into." On both computers, I can see the other computer's Firefox name in the list, and it reports "synced a few seconds ago".

But when I use the context menu and try to send a tab under "Send Tab To Device" the new computer is not on the list.

This article does not discuss this situation. For the case of "I don’t see my device listed" it just says "Sign In", but that has already been completed and is working on both systems.

Hi Firefox team,

I searched online about TLS 1.0 support history events. Looks like Firefox previously (around year of 2020) stopped supporting TLS 1.0, but later re-enable it to support some goverment TLS 1.0 website for COVID reason.

We now have a website(based TLS 1.0). That site is no longer available on Chrome, but it's still available on latest Firefox version by today(Mar 21, 2023). I'd like to know do you have a plan to officially stop supporting TLS 1.0 website again without exception? If so, when will it happen?

Thanks

I have read multiple posts & articles about cannot reach ups.com website. Nothing others did works for me. I have re-installed Firefox, cleared caches, started in safe-mode, on & on ... etc. etc. etc.

For the last week, FIREFOX has been slowly deteriorating & cannot reach various business websites:

ups.com Hmm. We’re having trouble finding that site.

foodlion.com 504 Gateway Time-out Microsoft-Azure-Application-Gateway/v2

I have run software to find malware & viruses, with no solution.

I have NO TROUBLE using CHROME to access the same websites.

Who has the magic answer?

Firefox completed an update today and all of my history is gone. Previous tabs can't be recovered. Even my bookmarks menu looked different. I was signed into my firefox account to prevent precisely this from happening. Where can I recover my history?

I have been running firefox on my macbook air for years. I just recently upgraded my O.S. to Catalina. I did this primarily because my old firefox would no longer update. I did the upgrade to Catalina then downloaded "new" firefox. I have both "versions" of firefox available. the old one with all my bookmarks etc. and the new one with nothing. I hit move bookmarks on the new version but the only options were from chrome or safari. How can I move over the bookmarks to the new one. Thanks

Website developer want the list of my extensions to reproduce the issue on their site. I am having more than 30 extensions and i doubt they will be able to reproduce it. Since developers not yet made disabling plugins easy (like opening a single tab in debug window, easily disable half of plugins in that window. See what happen. Quickly enable these back without manually selecting each one. And disable other half) it is not easy to find addon that is causing the issue.

Ideas: 1. at about:support page i can copy the list of extensions, but the developer would have to waste their time installing each one manually. Then they will be missing my extensions settings lowering the chance to reproduce even more. 2. Can i somehow export all my extensions and their settings so developers can easily apply it? I mean the way so i can be confident i do not supply them any sensitive data of the extensions. 3. other idea please?
