Trying to watch a video on Nebula and it will not load. Receiving the following errors:

NS_BINDING_ABORTED Media resource https://nebula.tv/static/small-video-h265-DaPPbwJq.mp4 could not be decoded, error: Error Code: NS_ERROR_DOM_MEDIA_NOT_SUPPORTED_ERR (0x806e0003) Details: Utility MF Media Engine CDM only support for media engine playback

Just made a new profile and wiped everything from my history following another issue which isn't strictly speaking resolved. I am unable to load image-dense websites with any consistency. Issues do not occur on other browsers. I receive similar errors on Twitch:

The resource at “https://assets.twitch.tv/config/settings.1c614f361eb0408365c5a3fce34f6bf7.js” preloaded with link preload was not used within a few seconds. Make sure all attributes of the preload tag are set correctly. www.twitch.tv The resource at “https://assets.twitch.tv/eppo/api/flag-config/v1/config?sdkName=js-sdk-client&sdkVersion=3.1.2&apiKey=3mv-BKCSZJDyZrwfqK86har6u13NgxRh.ZWg9bTRsZHJnLmUuZXBwby5jbG91ZCZjcz1tNGxkcmc&callback=__setEppoConfig” preloaded with link preload was not used within a few seconds.

My version is the most recent, 152.0.6.

After a few minutes, text searches in the address bar unpredictably stop working. This might happen right away, or it may take a while. The result is always Secure Connection Failed The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.

Here are the problems that I encounter literally every day: Randomly unable to access GMail: account selection entry screen does not respond, or drop-down account selection when logged on does not respond. Randomly unable to access URLs embedded in emails. Browser locks up unpredictably. Videos in Facebook randomly fail to render: the audio plays, but the bottom half of screen completely blanks. Randomly unable to access websites in general: "secure connection failed". Randomly refuses to search for terms entered in the address bar, with "secure connection failed". Widgets on web pages randomly fail to respond.

I'm using the VPN that comes with my AV package, and turning it off makes everything work again. However, I'm certainly not going to turn off part of my web protection (which I am paying for) in order to get Firefox to perform basic browser capabilities. TBH, all of this started when Firefox started aggressively promoting their own VPN, so it's quite tempting to put two and two together.

I would prefer not to resort to Edge or Chrome, but at this point I don't see an alternative as they do not have these problems and Firefox has basically become unusable.

Hi support and team,

I am seeking for your help, I look for the extension "ShopBack" which help me to track the online purchases, cashback / rewards.

However, I cannot search and install after I have remove it for some troubleshoot.

Looking forward to hearing from you soon. Hope I can get it installed and continue to enjoy the benefit.

Regards, Kong

Why do I continue to receive a message from Firefox after creating a New Profile?

Firefox This profile was last used with a newer version of this application. Please create a new profile. OK

A new profile PERSONAL #2 was created following the Steps to Create a New Firefox Profile.

What did I do wrong? how to correct, so that I stop receiving the error message?

Recent builds have changed the way that the user can direct queries to the various search engines that can be added (i.e. eBay, Wikipedia, IMDB etc) - to a new configuration that is awkward and forces more clicks.

Here is the method that currently allows reverting to the previous approach :

in about:config

Set string "browser.search.widget.new: to false

... and to delay automatic deletion of engines set "browser.search.widget.removeAfterDaysUnused" to thousands

Posting this for increased visibility for folks encountering the issue and in the hopes that Mozilla will consider not degrading a well-performing interaction pattern

why every time i open Firefox is go straight to signalqueryhub instead firefox. And how i can make it like normal(open Firefox and straight to Firefox instead of signalqueryhub).

I am watching a movie and would like to use Picture-in-Picture mode so I can continue watching while working, thanks to its floating window feature. However, I can no longer use it.

I have already tried clicking the Picture-in-Picture icon on the video, using the Ctrl + Shift + ] shortcut, and verifying that the feature is enabled under Settings > Tabs and Browsing > Media. Unfortunately, none of these methods worked.

I would appreciate it if you could help me resolve this issue as soon as possible. Aside from its extension support, Picture-in-Picture is one of the main reasons I chose Mozilla Firefox.

Thank you in advance for your assistance.

I am using Windows 11 on both my desktop and laptop. I began using vertical tabs a ways back. On my desktop I am able to scroll through the active vertical tabs with the mouse. But, I am unable to scroll the vertical tabs on my laptop. I have compared the Firefox settings on both computers and have been unable to find any settings that are different which could be applicable.

Roughly one third of my bookmarks all changed to sites I have visited recently. They still have the same labels, but when I click on them, they just take me to some random site I've visited recently.

I turn that off and still no Twitter and your system turns it back on again all by itself, your settings are doing what they want to do, not what I SAY to do. Now, I cannot get into Twitter.

I open Firefox, my browser, then I type in the site I want to open. It opens fine, however, when I try to open another site I want to open nothing happens except a little dot in front of the requested site keeps going back and forth, but nothing opens. I then have to close the browser, re-open the browser and key in the site I want. WHY? What am I doing wrong. Please keep in mind that I am not a computer savvy person and don't understand much about them. I do know however that Firefox used to work on my computer before update 150 and 151 were downloaded without a hitch. I have tried everything I could think of to fix the problem without success. I am beyond frustrated and need this fixed.

So I just upgraded my pc and it bricked my windows and to reinstall, I forgot to save the Firefox data before doing so because I thought it wouldn't cause any issue, well, now all my bookmarks etc. are gone and I'm wondering if there is some sort of backup somewhere saved by Mozilla in the cloud.
