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!

Hello This evening as I was going to pay for a book on a site well known to me, I notice that I don’t see a lock to the left of the address. I read your page 'Mixed content blocking in Firefox' after seeing that its little French sister was not up to date and it seems that it is the version of Firefox installed tonight that is behind this big change. Even my bank’s site no longer shows padlocks and it’s destabilizing. Why such a change without explanation??? I only read information about the split view in the same tab (which seems very useful) but nothing about this disappearance of the lock... Can you confirm that it is indeed the version from tonight 27/03/2026 that made this change at first glance worrying.

Thank you in advance and have a good day.

After going into Home Depot Canada's website, I can't entre into their departments sections, just see nothing. Maybe somethins wrong with my Firefox's settings? Please help. Thanks.

When I try to make a Google search I get the following message, "I'm not a robot" with a reCAPTCHA: "Our systems have detected unusual traffic from your computer network. This page checks to see if it's really you sending the requests, and not a robot. Why did this happen?". This happens on Firefox, but not Chrome or Edge. If I 'Allow' Google in the 'Exceptions - Cookies and Site Data' then I do not get the message, but it takes several seconds for Google display the resulting page. However, if I delete the cookies/cache the message will return and I have to redo the reCAPTCHA. I have scanned with Malwarebytes, Bitdefender, Hitman Pro, Trend Micro House Call and Microsoft Defender, nothing detected. Running Win 10 (64) with 'Extended Security Updates', Firefox 147.0 (64), no additional Extensions or Plugins. Also I uninstalled and reinstalled Firefox.

I already downloaded firefox vpn for windows and already have the firefox vpn extension icon on the upper right corner of my screen.

If I click on that icon extension nothing happens. What can I do ?

I cannot login into Kick.com, is it because am on Windows 10? If i use any other browser, it works fine no problems!! (the error it gives me is attached)

i want to change my email address stevennyan100@gmail.com to stevennyan41@gmail.com because i have no longer have access to the email address

upon opening firefox the following address appears in the search window:

https://eventseekspot.com/?path=firefox/newtab&u=864940da25d1ae22&subid=11119&channel=1

why? and how do i make it go away

Since latest upgrade (1/16/2026) I cannot log in to Outlook email. This is specific to Firefox 147.0.1 (Chrome and Pop Peeper logins to Outlook work fine). I tried clearing cache, updating, restarting, rebooting, trouble-shooting mode, private window etc. to no avail. I get 400 error from Outlook.

Здравствуйте. Не хватает гибкая настройка главной вкладки с моими сохраненными сайтами, а именно отключение "посещаемые сайты", чтобы их не пришлось каждый раз "удалять из истории" или "скрывать" из главного, ведь для меня это лишний мусор. Возможно ли добавить такую настройку?

Спасибо за внимание! Прошу извинить, что пишу на своём родном языке, так удобнее выразить свою мысль поточнее.

When v143 was released something happened to the shortcuts row(s). Regardless of refreshing efforts, rolling back versions, and searching the forums, there's no way to consistently get the shortcuts back. Sometimes they appear with a new browser instance, sometimes they don't. They don't appear with new tabs, and they don't stay when they do appear with a new browser. Grrrr. Please restore the shortcuts!

You might be wondering why we lumped fractions and greatest common fractions together.
The fraction

The first time the inline table creates a new line second time inserts in fraction where it is (which is how I want it) How do I prevent it from forcing a new line?
