After the last Firefox update, I can no longer open download files (PDFs) from websites in Mac Default Viewer. I have tried the other settings such as open with Adobe, Ask, etc., but they continue to only open in the browser. For work, I download hundreds of documents from a county site, so having them open in my default viewer when I click the link was very useful for a productive work flow. I have tried to open files with my viewer from other sites, but it fails with those too. My tech team tried to help but seems to be a Firefox issue. Settings - Downloads - Files and Applications - PDF - Use Preview (or anything else) is not working. Firefox 157.01, Apple M2 Pro, Tahoe 26.6.2.

Firefox just updated to 157.0 and will no longer open PDFs in a default viewer even when I change the settings. My setting say they are set to open in Mac Viewer, but continue to open in browser. I even tried to set it to open in Adobe still opens in my browser.

Ever since the last update, I can no longer watch recordings on xfinity stream with Firefox. What happened? Can I fix it? I sometimes have to start watching programs late, but they wont play while recording. I can watch those same recordings when they are finished, but not while they are still recording. I can watch those same recordings while recording on Chrome and Safari so it's not an xfinity problem. But for some reason not on Firefox anymore Is there a setting I need to change? Thanks Ron

ever since last update... can't send emails

Mozilla Account works normally directly inside Firefox, but logging into Mozilla Accounts through Thunderbird's Add-ons manager fails during the Firefox handoff.

Steps to reproduce: 1. In Thunderbird Add-ons, click Log in. 2. Thunderbird redirects to Firefox, showing "Continue with Mozilla account". 3. Click Continue -> Firefox displays "You could not be logged in. Please try again."

Troubleshooting already tried:

• Created a brand-new Thunderbird profile (thunderbird -P) — same failure occurs.
• Cleared cookies/site data in Thunderbird and cleared Firefox cache.
• Disconnected existing Thunderbird/Add-ons connections from Mozilla Account dashboard.
• Extensions and add-ons themselves install and download normally.

Hi - Just recently (within the past week) I've been running into several issues with Google Drive on Firefox, namely that it doesn't recognize that I'm online so I can't open or edit documents. When the pages do load during brief moments of connection, the page never fully loads and the little dot on the tab continues to move back and forth, showing there's still more to load.

I've tried the following with no luck: - clearing Firefox cache and cookies - signing out and signing back in to Google Drive - restarting Firefox after doing each of the above - restarting my computer - checking to make sure I have the most recent Firefox version (I do: 157.0.1)

I am able to log into Google Drive in Chrome and have no issues at all. Also, I'm not having this issue with any other websites. Do you have any guidance for me? I really don't want to move over to Chrome, but my entire job requires Google Drive, Google Docs, Google Sheets, etc.

Thank you!

QR code for BankID loggin and KIVRA (in Sweden) is not visibel when I use latest version (157) of Firefox. When I use Firefox version 152 is it working. I have a mac OS version 10.15.8. What could be the problem?

Bring back my access to the Artstorefronts.com website. I do business with them, they carry access to my website: Onenessofbeautyandsoul.org. Are you blocking it, or is it someone else?

additionally, i cannot use my mouse anymore to speed up scrolling through my favorites. also, i deleted a folder from my favorites, but that folder still shows up in my favorites.

After Firefox upgraded to the latest version, Google no longer opens up, bookmarked websites no longer have my username, password, or login account info, and do not recognize my account. Syncing caused all kinds of problems. I'm not happy with Firefox anymore and wish to remove it from my laptop . How do I do this? Sorry...I was once a happy camper. Barbara

All of a sudden all of the videos I watch on YouTube with Firefox are defaulting to mute on my Macbook. I haven't made any changes to settings, etc. I don't have a YouTube account so I can't make any changes there anyway. I am having to unmute each video before I watch it.

This morning, I can no longer download (Save) files to my computer, nor check/change settings in Firefox. Tried all troubleshooting steps to no avail.

If I delete and reinstall Firefox, will I lose all my Bookmarks, etc.? Running version 157.0 (aarch64).

Appreciate any help!

The edit icon on lower right splash page selects which photo for background display. My photo will not display and ignores my selection. Nothing happens. I have spent 24 hours trying to customize my Firefox but cannot complete my goal. Help!
