I'm using Firefox 129.01 (64-bit), trying to log in to my Tufts Health Plan account, and get a security warning (screen shot attached). Customer Service at Tufts Health Plan tells me that I should use Chrome.

Should I ignore the Warning and proceed?

Firefox releases email addresses and our data to third parties!

I installed the Arc browser and Arc offered to load my bookmarks from mozilla. Out of curiosity, I let it, and it loaded my bookmarks and folders smoothly. Arc didn't navigate Firefox to the login page, so Firefox released my information without asking me.

What probably happened in the background was that the Arc browser told Firefox which email address it was requesting data from, and Firefox handed over the data to it "on notice". Firefox was not even convinced that the real owner of the email address asked the Arc browser to synchronize the folders.

Is it the famous Firefox reliability?

I'm talking about how when you go to fill out a text input, it'll suggest that input next time you go to a similar field. Well, that system just saved my social security number as an input after I filled out a government form. I would like to turn this feature off now, and delete the history of it if I can. Is there a way I can do that?

I'd attach an example image of a different website, but the box goes away when trying to take a screenshot.

OK - I must be missing something. On my previous browser, Opera, if I wanted to see details of my passwords then I needed to put in the computer password, so keeping them quite secure. However, Firefox seems to let anyone using the browser to access the full details of all my passwords, even offering to copy them! This has to be the most insecure approach possible - surely this can't be correct, can it?

I visited eBay.com yesterday, Now, every time I search art or photos, an eBay page selling such items pops up. Adblock Pluse extension does not stop it.
