I’ve been noticing an issue with YTS-type sites on Firefox. The site either loads partially, the player doesn’t start, or it keeps buffering without playing anything.

What’s strange is that the exact same site works perfectly fine on Chrome and other Chromium-based browsers. Videos load instantly there, but on Firefox it either breaks or takes forever.

Things I’ve already tried: – Cleared cache and cookies – Disabled all extensions – Tried in private window – Checked network (no issues)

It feels like something related to Firefox compatibility with the video player or scripts used on these sites.

I also tested another version here which seems to work better on Firefox:

ytsmx https://ytsmx.stream/

Not sure what’s different (maybe a different player or encoding), but it loads without issues for me.

Has anyone else faced this or knows what might be causing it?

If I go to AOL.com they useually have 40 or so news articlaes/ads you scroll through. Several weeks ago the text for the articles stopped displaying. I have tried other browsers and the text shows up. Not sure what setting may effectr this.,

Currently the built-in VPN operates via a blacklist system. Where it is turned on browser wide, with exception of sites you manually add to the blacklist where it will turn itself off when on those sites.

To preserve the allotted 50gb data limit for using the VPN, I would ideally need to turn the vpn off of every website that I don't need it to be on which is extremely tedious even if it's a one-time annoyance.

It would be better if instead(or in addition to) we had a whitelist option where we could have the VPN not be active browser wide, with exception of any site we add to the whitelist. I would much prefer this because there's only a handful of sites that I would need the VPN to be on.

Setup: macOS Tahoe (26.4) and Firefox 149.0

Behavior: Out of the blue this morning, every website I try to visit in Firefox returns "Looks like there’s a problem with this site". Every other browser works fine.

Things I've tried, that haven't fixed it: - Ruled Out DNS: Sites like 1.1.1.1 and my home router's IP return the same issue in Firefox, but also resolve in any other browser. - Firefox Safe Mode: no fix - Deleted All Settings, Reinstalled Fresh: - Removed the Firefox App, deleted:

       - ~/Library/Application\ Support/Firefox
       - ~/Library/Caches/Mozilla
       - ~/Library/Caches/Firefox

...and then downloaded and installed 149.0 fresh. - Refreshed Firefox (via [link] - about:preferences (toggled between FALSE and TRUE, testing each time) via this YouTube video

- network.dns.disableIPv6

- network.dns.disablePrefetch
- network.dns.disablePrefetchFromHTTPS
- network.dns.disable

....and in desperation, I checked my Mac for Malware (clean)

I'm at a complete loss: every other browser works, but Firefox is a 100% fail for all websites. Any thoughts?

I have Firefox set to always ask about how I want to open/save PDF files. Within the past couple weeks, I've encountered an issue with opening PDF files. When I click on a PDF and select "open with Firefox," the PDF opens in a new tab on Firefox, but it also opens in Acrobat. When I select this option, I just want the PDF to open in my browser, and I cannot find a way to stop it from simultaneously opening in Acrobat.

The account dwr50@excite.com is no longer active yet firefox keeps trying to use it to log into things like this support area. How can I get rid of the old email address ?

I am running Firefox 149.0 (64-bit) on Windows 10. FF tells me that there is an update. I downloaded the update, and when I restart FF, it does not update. Version 149.0 is re-started, and Help --> About Firefox again tells me to restart to upgrade. I have tried the upgrade at least three times.

I deleted the VPN button after the latest update and would like to get it back. I found VPN in the Settings but the VPN button is disabled, and nothing happens. Need suggestions -- thanks.

I have set the setting for PDF files to Always Ask. When I select the "Open in Firefox" option from the dialog, it opens the PDF in a new tab in Firefox and ALSO launches Adobe Acrobat and opens there. I have not seen this bizarre behavior before today. How do I fix it?

When I write emails or whatsapp messages Firefox signals as false all the words that don't conform English orthography. I would like to switch language either automatically or quickly. What do I have to do?

Hi, ok, so my computer just randomly updated my Firefox Browser and now all of my bookmarks, saved passwords, extensions, themes, and history is gone. I used the links on the support website, but they were not helpful at all. I am logged in with the same account I was originally logged in with prior to update 149.0 (logged in with gmail). When I sync data in settings, it automatically imports my Safari and Chrome information (which is not what I want). I try to import my bookmark and password history from the saved HTML and CSV files under Mozilla Firefox, but I don't have the ability to do so, as the files are essentially 'greyed' out. I have tried every step to troubleshoot and every link that is related to my issue listed on Mozilla's support with no success. I have even searched my issue on Google and Reddit. Please help!!

When I open Firefox, all my bookmarked sites start loading at the same time. I have unchecked, the "Startup Open previous windows and tabs" option in General Settings. I also deleted, and added Firefox again, but all sites are still loading on opening Firefox. (Chrome browser is fine.) Any ideas? Thanks!

Hello,

Please help.

Every time I start Firefox lately, it keeps prompting me: "You must log in to this network before you can access the Internet." I have no idea what this means and have no problem accessing the Internet in any case. What suddenly started causing this !#@%$ message and how do I turn it off?
