I received an email from breach-alerts@mozilla.com informing me that Mozilla Monitor⁩ discovered a data breach that includes my personal information: Unfortunately, I don't know if this is a legitimate email from Mozilla. Can anyone confirm if it is or is not?

Thanks

I have changed operating systems from windows to linux mint. I made sure to sync my profile before uninstalling, but now the profile looks to be empty. there are no saved passwords or bookmarks. This worked when I changed between different windows devices last year, but this time it seems stuck. I will check on a windows device when able, but in the meantime, are there any other ways to troubleshoot this?

In Firefox, I have several windows open, each with many tabs. (And BTW, I love the Firefox tab-organization feature.) I would like to empty the cache and delete all cookies. Will that close the open tabs? Is there a way to delete the cookies, empty the cache and preserve all windows & tabs?

      Thank you!

When I watch videos (reels) on Facebook, and sometimes on YouTube, I share a video either to messenger or my page, the whole string of videos I have already watched goes back to the beginning of the string everytime. Only Firefox does this. I have 3 other browsers that work fine, but I prefer Firefox of course.

I'd appreciate a fix for this, Thanks

Hi Mozilla Community,

I am running Firefox on Windows 11 and I'm encountering a strange issue regarding the UI updates.

The Issue: My Firefox browser updates automatically to the latest version. However, my Default Profile is visually stuck on the old UI design. It does not reflect the recent interface changes associated with the update.

The Troubleshooting Context:

• I have verified that the browser itself is technically updated (via Help > About Firefox).
• The strange part: I have other Firefox profiles on this same machine. When I launch those profiles, they correctly display the new, updated UI.
• This issue is isolated strictly to my main/default profile.

Has anyone experienced this mismatch where the version number is correct, but the UI fails to refresh on a specific profile? Is there a specific fix for this?

Thanks in advance for the help.

I receive this Error msg trying to access Settings option in the AJC epaper section https://editions.ajc.com/shortcode/AJC412/edition/f117d96a-c78b-4df3-4b6a-0e587f6cfd22 on a Firefox Browser:

Application error: a client-side exception has occurred (see the browser console for more information).

My friend recommended this browser to me. When I tried to customize it, I couldn't find an option to change the hotkeys to my preference. I consider this feature important since I use it for work. Can I do this somehow, and is there any plan to add such a feature to the settings?

When accessing important accounts on websites, like financial websites, I've always heard you should close your browser when you're done with the secure website. If you log on in a PRIVATE window and close the private window afterword but leave the main FireFox window open, is that the same thing? I think it is and the private window will delete any login or activity info as if you closed the browser, I just want to confirm with someone more knowledgeable before I make a bad assumption. It also seems to have the added benefit of deleting anything you might download and save elsewhere from the download folder so you don't have to delete it from the DL folder and then the recycle bin. Seems like it's good practice to use the private window this way. Again, just looking for a 2nd opinion.

Thanks,

My emails used to display in date order but since a Mozilla upgrade they are now grouped as Today, Yesterday and Last Week. Is there a setting to alter this back to one list in date order please?

I have a new Mozilla (FireFox) account and keep getting emails that say I need to confirm it. They include a button to do so but I'm not clicking it unless I get better information from you. Please help. The email swears my account will be deleted if I don't confirm it. What do I do?

I am 82 years of age and did not grow up with the Internet. I have a total of only 8 hours of training on a PC. I have no idea how my PC got into 'safe mode' and now all of my extensions are disabled. I do not know how to exit 'safe mode' to allow the extensions to be enabled again. I tried following the instructions as provided, but to no avail.

Hi,

I use the Page Info window quite regularly, it used to be accessible via the right-click menu but this seems to have been removed in recent updates. I can still access it via Ctrl+I, but this isn't as convenient as using the menu.

Could you please tell me how I can put this useful feature onto the menu / toolbar as a shortcut?

Thanks

Owen.

For some strange reason, I get this response when logging in to local newspaper on Firefox..image one. When loading the same newspaper on Edge, I see this instead...image two. I've been in contact with the newspaper but the techs there can't figure what's happening. Is there a setting I have wrong on Firefox? Thanks for your time.
