As of 7/10/2025, Xfinity Streaming does not open through Firefox. I much prefer Firefox to any other browser so I am a little mystified as to why all of a sudden Xfinity Streaming does not open. I receive my Comcast email through FireFox but when it comes to streaming content, the Xfinity logo just sits there and does not open.

I keep a lot of tabs open (~60) in any particular session - I find it's faster in this way to get back to a site.

About every six months or so, I lose *all* these tabs because of Firefox's inadequate session backup system. It only saves two or three total backups, some of which are completely out of date. But the worst scenario is when (1) some site pops up a new window; (2) I mistakenly close my main window before the new window; (3) I open this new saved window once or twice by accident, causing my 60-tab session backup to be overwritten.

Using a third-party session manager (I have tried all the well-known ones) can mitigate this problem, but doesn't really solve it because the re-opened sessions aren't quite in the same format as Firefox sessions and so lose information. In particular, I often lose each tab's icon as well as metadata for Tree Style Tab.

Could Mozilla please consider a more robust session backup system for Firefox? All it would take (I think) is to allow the user to choose the total number of backup sessions and the frequency at which a new session is added. Thank you!

According to this article I should be able to activate autofill credit card details in my country https://support.mozilla.org/en-US/kb/credit-card-autofill But the option is no where to be found and in about:config I can see it is restricted to a few countries mine not being one. I can not change the list with countries either, actually I can not change anything nor search in about:config. I am running Firefox 140.0.4 (64-bit) EDIT I made a a master password, which then made it possible for me to edit in about:config. I added my country to the extension and now I can activate it.

I am writing an email with two photo attachments. Preview will not work (open) for me to double check the correct file is being sent. It will, however, open a file with only text.

Hello,

I just closed FF (latest version) and opened it again and all my tabs are gone. I had a private FF window open, so I am guessing this is the cause.

Is there a way to get get them back?

Thanks

Hello, Just updated to the latest FF on Windows and I want the old search engines option.

Now there's a dropdown menu to choose from, which is nice but makes a redundant click (click the dropdown and click again to chose).

Before the update, after typing a string, I would have at the bottom of the the search bar a list of the available engines, clicking one of the icons, would start the search, thus only 1 click.

Is there a way to get this back?

Thanks

I returned a phone that I had for 2 weeks (the phone was a Motorola G Stylus 2024, if that's even relevant), and while I did a factory reset on the phone before returning it, I am worried that my Firefox account information is still accessible through the device.

One reason why I am worried is because, when looking at synced windows open, *everything* that I had open on there was open and accessible through my account. Another reason that I am worried is because I did not log out on the device before returning it to my local Best Buy.

It'd probably be impossible to track down the exact phone that I had, but can anything be done? Should I redo my log-in password for Firefox (or even all the sites that I used on that phone) or am I worried over nothing?

I am using the FireFox PDF Editor to annotate a PDF, however, no method of me saving the document (whether that is save as, or save as PDF) will allow me to save any annotations on the document. If I try doing save as PDF, the preview shows up as blank sheets of paper, when I click "save as" it only saves one page of the 31 as BLANK. If I try doing normal save as, the saved file is un-annotated.

Please help... thanks

AMD ReLive instant replay does not work if mozilla firefox is open in the background while playing a game. It works fine with Google Chrome running in the background, closing firefox "fixes" the issue.
