The Discord website does not play embedded video files (mov, mp4, etc). This is an issue specific to Firefox, and is not present in other browsers such as Chrome. This issue is only for video files and not embeds from sites such as Youtube or Twitter/X. Furthermore, when downloading these videos, they play solely the audio and not the video part of it. This is not an issue with any other downloaded video. I have tried clearing my cache and restarting Firefox, as well as disabling my extensions. None of which has worked.

Using Firefox 136.0 and previous vers. Some web pages are displayed in portrait mode. (or seem to be) In Firefox these pages are??? not right. If I copy and paste url to MS Edge the page displays properly even although the presentation is still in portrait mode (or seems to be). i.e. the data displayed on the page does not go out to the edges of the screen but sits in the middle in portrait mode for example see: https://www.scotlandspeople.gov.uk/

Attached images show Firefox and MS Edge screen grabs and https://en.wikipedia.org/wiki/Main_Page which displays correctly in Landscape mode (or seems to)

When I restart the system after a refresh or after shutting down, Mozilla takes FOREVER to connect/load webpages. (I can get on-line immediately after a reboot using Chrome, however). It is extremely frustrating as I have to leave the system on a webpage all day long and over-night so as not to have to go through the hassle of trying to get it to connect after an absence. Even when Mozilla requests I re-start for an update, it still takes forever. what is causing this and how can I fix it? Be advised, I'm not a computer whizz so please explain in non-tech talk. Thank you, Joe

Hi, I use Firefox all the time, love it. But I have noticed a problem.

If I have say 7 tabs open, none of them doing anything, then go away from my laptop for say 20 minutes, when I come back the fans on the laptop are screaming. Even if it was minimise.

I have a fairly modern laptop Dell GSeries1522, 12th gen processor, 16gb ram, i7.

I have tested this issue using Edge and Chrome with exactly the same tabs open and the laptop is all quiet. I'm on the precipice of moving to Edge. Happy to provide more information. Task Manager now shows FF using 1223.0mb of memory, Edge 466.7mb. They are both in "efficiency mode".

Any help or advice would be great.

I can't access my Manage Accounts page. When signed in, I've clicked on 'manage accounts', (via Browser menu, and in Settings) and it opens the error message below. I've tried to open the page on 'troubleshoot mode', restarted Firefox several times, and logged out and in, several times. I'm always getting the same error message. I'm on Windows 10. I desperately need to update my email, as my log in is being deleted and this is the only page to do this from. Can anyone help?

Session Expired Sorry, something went wrong. Please sign out from the browser menu and try again.

Hello, I just updated Firefox to version 136 on my MacBook Pro. I was playing a 4k YouTube video, and at 16 minutes and 10 seconds in the video froze. If I moved the cursor the pause button and all of that would come up at the bottom, but when I clicked on the option to exit full screen it did not respond. I pressed the escape button and that did get me out of full screen, but the video window did not apply the right formatting. I'll include a screenshot so that you can see what I am talking about. After exiting full screen, if you look at the bottom of the video window, the option to go back to full screen is cut off. Closing Firefox and relaunching it appears to have things working again, at least for now. I thought it would be best to report this just in case it isn't an isolated glitch.

Hey everyone,

I’m running into a frustrating issue with Firefox. Whenever I paste a large amount of text (especially code) in one go, Firefox freezes and becomes unresponsive. This happens frequently in various web apps like ChatGPT and Make.com.

It’s not a one-time thing—it happens consistently when pasting large blocks of text. Has anyone else experienced this? Is this a known issue, or is there a way to fix it? Any tips or workarounds would be greatly appreciated!

Thanks in advance!

Hello,

I'm new to Firefox after changing from another browser.

I am looking for a setting to turn on notifications from sites such as Instagram to notify me with a pop-up window from the web browser.

Is this not available on Firefox?

If not available, I'd like to suggest this as a new feature.

If it is available, would someone help me find this to turn on when I signed into Instagram? It did not ask me if I wanted to turn on notifications.

Thanks

For the past few days when I use Firefox and Thunderbird my entire screen will randomly start to flicker, at times very quickly and rarely the entire screen goes black for second or two. This behavior immediately stops when I close the app. It does not happen with any other app. I've tried disabling hardware acceleration in Firefox and that didn't help. Both apps are on the latest version and I also updated my video driver. Tried removing the two add-ons I have. I'm on Windows 11 Firefox 136.0.

My Firefox window keeps expanding to fill the entire computer desktop. I make it smaller, and it expands again. How can I fix this? I like to be able to adjust the size of the window manually and have it stay that way!

Recently, whenever I access a local TV stations news post and try to read it, I get the pop-up shown in the attachment. Why is it happening and what can I do to eliminate it?

Hi,

I have a question to the Firefox Snap permissions. I want to give Firefox the minimum of permissions which you can grant via Settings => Apps => Firefox Web Browser, because of security reasons.

So, a lot of them are self-explanatory, but there are some where I can’t imagine what that means and whether Firefox really needs such permission to run correctly and save or not. These are the following:

- Run in Background - Detect network devices using mDNS/DNS-SD - system-files - gsettings - Access hardware information - Mount-control - login-session-observe - opengl - system-packages-doc - Read/write access to U2F devices exposed - Access energy usage data

So, my question is: Does Firefox really need one of these above permissions to run correctly and save (I am asking because I don’t know if some of the above permissions are for security reasons activated) or can I turn them off?

Thank you!

For many years now I've had Firefox clear

• browsing & download history
• temporary cached files and pages
• saved form info

but not

• cookies and site date
• site settings

This worked flawlessly until Firefox updated to version 136, at which point all cookies were deleted and I was signed out of every account on every website.

Looking at the settings page, the option to delete cookies and site data when Firefox is closed is now enabled. I don't remember what this setting used to look like, but I did not change it recently.

Unchecking the box seems to work, but I shouldn't suddenly have to do this, and the "damage" is done.

Why did the update to version 136 sign me out of every website, and how do I protect myself against this happening again?

Hello, I have restarted my laptop only to find that my previous session was not retriavable anymore, so I went to my History and to my utter surprise it was gone. Years of history deleted. Could you help me understand what on Earth just happened?!?!?! Thanks in advance

I was using the control key with single word urls, like "nfl," as a shortcut to go to nfl.com. That had been working until the most recent update, albeit with a right-click menu appearing after Firefox opened the desired page. Now, when I hold the control key with the location bar active, Firefox brings up the right-click menu without going to the desired page. For example, if I enter nfl.com and hit ctrl-enter, the browser stays on the current page and brings up the right-click menu even though I'm not clicking the mouse. Is this a bug or new behavior. (Note: I have Firefox set to autocomplete only bookmarks.)

refer attachment, i am unable to access this site. completely working fine in edge. what could be the issue as i reinstalled firefox and still is facing the issue.

I've been using the firefox pdf viewer for quite some time and it's worked quite well. Within the last few days though I've developed an issue.

When I open a pdf it opens correctly for just a brief second (standard text, white background, nothing unusual) and then switches to something like the attached image (black background/ text and such). I have not changed anything that I'm aware of, though I did just recently install a new firefox update (136.0 64-bit windows 11). I didn't notice any articles or comments about this particular issue here yet, so figured I'd ask for some help.

Anyone know how to resolve this? Or other things I should look into?

Thanks for your time, Derek
