Firefox Community Forum

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?

When I went to https://www.mozilla.org/en-US/products/vpn/ and decided to purchase a Mozilla VPN prepaid annual subscription part of the reason was this "feature"

"Easy Firefox integration with the Mozilla VPN extension (Windows only)"

There is nothing easy when clicking on the download for the Mozilla VPN extension yields a message that the add-on or extension has been blocked. The explanatory link provided is https://support.mozilla.org/en-US/kb/add-ons-cause-issues-are-on-blocklist. That lets you know that:

"When add-ons violate Mozilla’s policies, compromise user safety or privacy, or fail to meet user expectations, Mozilla takes action. This may include disabling add-ons in Firefox to maintain a secure and reliable user experience. "

So, when will Mozilla stop violating Mozilla's policies so that the Mozilla VPN add-on is fit for use on Firefox v 149.0 [without free VPN] running on WIN10 64?

The account dwr50@excite.com is no longer active yet firefox keeps trying to use it to log into things like this support area.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 recently installed an rtx 3060 12gb on my old system (Win10, ga-h77-ds3h gen3 mobo + xeon ivy bridge cpu). I installed latest Nvidea Studio drivers. Everything seems fine apart from Firefox, which showed visible artifacts/flickering lines on the screen. I disabled hw acceleration in Firefox settings and now instead of the lines I just see micro dots which change position frequently. As recommended by AI i changed some other settings in about:config but the tiny dots are still there. Starting Firefox in safe mode they are still there. On MS Edge its fine, there are no dots/artifacts.

Is there something else that might fix this or there is nothing that can be done, its just how the rendering engine works on older systems and rtx 30s cards?

I'm using an out of date Windows 10 laptop. I am aware of the Windows 10/11 thing. I know. I've got my own reasons for not updating this one, it's not my only device. I get it. I understand. I know. My settings are how they are on purpose. I do not need to be nagged in this fashion.

How do I turn this off? I can't find it in settings. It's not appearing on any of my other browsers. It's just Firefox. Please help, it's driving me crazy.

Thanks in advance.

I have enabled the option to open the previous windows and tabs. I had one window that I always closed last as it had a lot of groups that are important for my work, so it used to open every time I started Firefox. Sometimes, even if I closed the window by mistake without closing other windows, I was able to get it back by pressing ctrl+shift+n.

But yesterday, I might have closed it by mistake and when I pressed ctrl+shift+n , it didn't come back. I wasn't able to access my window and now it's all gone. I don't see anything in recently closed windows in history.

I need those tabs back as they are very important for my work. they were a lot of tabs. I had many groups but now all are gone. I tried by using the previous.jsonlz4 in the sessionstore-backup by renaming it in the default-release profile as sesstionstore.jsonlz4 but still wasn't able to access my window.

I didn't clear my history as the tabs opened in the window still show up in the history.

Kindly help as soon as possible

I updated Firefox to 145.0 this morning, and after Firefox had restarted, it had lost all bookmarks and the bookmarks toolbar. I have spent all day following links to correct the problem and got nowhere. I have restarted Windows and Firefox countless times - no change. I've even tried reinstalling Firefox over the existing version. If I go to bookmarks > manage bookmarks > restore and backup, sometimes that will load, others not. When it does load, it fails to find a file to restore from. 10 years of bookmarks, links & research vanished.

Can someone please provide a solution (preferably in Layman's terms) to this??

When a generic Search is done or even if one has Search engines under Settings, Wikipedia comes upo but not Grokipedia which is very good and getting better and better.

After updating to version 149.0, videos on hdrezka.tv do not start after clicking the play button.

Steps to reproduce:

1. Open any video on hdrezka.tv.
2. Click the Play button.

Actual result: The player stays inactive or shows a loading icon.

Expected result: The video should start playing.

Note: I have tested this on version 148.2 and it works perfectly. Upgrading to 149.0 or 150.0 Beta breaks it. Reinstalling 148.2 fixes the issue.

I've just now noticed that whenever I open the website hxxps://www.hex-rays.com it will hang without finishing loading for a couple of seconds, then the entire browser will freeze. I've already tried on a new profile, verified that no addons or plugins are installed there, and no DLLs hooked into the process. This happens on my physical PC and in an (almost unused) VM, with an ancient version 134.0 and the latest 149.0.

Can anyone else replicate this? Should I create a bug report?

Hi, I wonder why the "m"-function isn't working anymore. For example, when I stream movies, I often use the “m” key to mute the sound. Recently, the search function has started appearing at the bottom as well. Is there a way to turn off this new function? If I want to search something I'd like to press buttons Shift + f as before. Thx for your attention. Cu.

I am currently testing the new Mozilla browser VPN and it's really cool, I love how you can enable/disable it at a site level. That being said, the options to do this are quite limited - I feel like for me personally, I'd love to be able to "enable on this website" list. So for example if I want to ONLY use the VPN on Google.co.uk, I can enter that into the list, rather than having to exclude a bunch of sites I use, just to enable it on 1 website. Thanks in advance!
