Firefox Support Forum

For a few days now, I have not been able to play videos. I get this message in the video screen: "If playback doesn’t begin shortly, try restarting your device." When I opened Firefox in Troubleshooting mode, the video played OK and then when I stopped Troubleshooting mode the videos continued to play OK. However, on the next day the problem reappears. What's going on? Thanks in anticipation, Frank

I have tried all of the about:config options to disable the auto-reload of the tabs. I have this working fine on my old machine macbook pro 2015 (same firefox version), but on the macbook pro 2019 i cannot get it to stop. Any help would be great as I need to switch between tabs during meetings and dont want them to keep relaoding

Hello my dear friends, Hello my beloved family, Hello Everyone,

This is the first time reaching your support because i never had any issue with any of your products ( I mainly use firefox as a browser for pc(ubuntu) but also on android devices).

I am writing you this email to express my gratitude and happiness for being a faithfull user since your debut(at least since when i had internet and a pc in the old days :D)

I really loved your professional attitude. I really learned alot from YOU. I really love you.

Plz continue your greate ACTIONS( at least this is what i think) and don't let the giants of internet ( i won't name any company so they don't sue me hhhh) try to confuse use or steal your faith in the "STRONG COMMUNITY".

YOU KNOW WHY BECAUSE ALL THESE giants BETRAYED MY EXPECTATIONS (at least the major ones that i know) BUT ONLY ONLY ONLY ONE PRODUCT NEVER BETRAYED MY EXPECTATIONS !!!

===============================================================

THIS PRODUCT IS "FIREFOX BROWSER" (i swear to god to all gods in all languages that this is TRUE at least for me :D)

Really love YOU ALL. Your Sincerally. Your thankfully. Your Brother.

I don't want a dark theme and have tried numerous times to change it to a light theme. Within a min. Firefox returns to a default dark theme without me touching anything. Is there something that I am missing or is this newer browser in need of repair? This is getting old, I have used Firefox for years, never had a problem with kind of issue before. Thanks

FireFox Developer 99.0b8 (64-bit) on the "aurora update channel" on Windows 10 PC (version 1803, build 17134.2208)

I notice whenever an update is pending (the green dot appears in the icon for the "Open Application Menu"), FF becomes unresponsive in a way. When it happens: It does not totally freeze. I can select/switch between existing tabs & scroll thru their pages. I can close tabs. I can open a new empty tab. But I can't load or refresh any pages. The only fix is to do the update, and re-launch.

Since the developer edition gets updated frequently, it is a pain.

I like the Developer Tools! But... How can I scale back the FF "update frequency", or "change the channel", so updates are, like monthly at most?

thank you.

I recently upgraded graphics cards from an Nvidia GTX 1080 to an AMD 6900XT. Since then I noticed video stuttering on YouTube while playing 4k videos, especially noticeable at 4k/60FPS (example video ). Prior to the upgrade, I was not experiencing issues.

I monitored task manager as the video was playing to see CPU usage, which was sitting at 25% (4 core 8 thread CPU). GPU usage was fluctuating from 1-3%.

I tried resetting all the changed configuration options in about:config, removing all add-ons, "Refreshing" Firefox, and ultimately uninstalling and reinstalling. Nothing has worked so far except for "Troubleshooting mode" in about:support. In that mode, I experience no stuttering and GPU usage rises to 25-35% with the video playing, even before I reinstalled.

This most likely isn't a networking issue as the "Stats for nerds" option on the YouTube video shows I have 10-20s of buffer while the video is still stuttering.

I would like to find out what's different about Troubleshooting Mode that is not giving me the same problem while in "Normal Mode". Any advice?

When I download now (.cpp files) I am no longer able to open the files with VS community without the file being downloaded on my computer instead of temporarily stored in my ram. This is critical for me when marking as a TA.

I have just installed the developer edition of Firefox and on the screen where I can install extensions/themes/add-ons, there is a link to create a custom theme. https://color.firefox.com/?utm_source=firefox-browser&utm_medium=firefox-browser&utm_content=theme-footer-link

It loads a blank page and nothing else.

Hi After updating to version 99.0.

I am using Windows 10 Pro on a desktop. When l log in using chrome,I am taking to TikTok web page. I am using same extensions in FF and Chrome.

Using Outlook Webmail on Firefox, I used to be able to drag attachments to my outgoing email to attach them. Now when I drag an attachment, I get a no symbol. This just started last week. I thought it might have been a new protocol with webmail, however I tested this on Chrome and dragging and dropping attachments to webmail still works there. Any idea why this started and how to fix it?

Hello,

As of this morning I am no longer able to drag files from explorer and drop them into an email to add as attachment. Drag & drop functions just fine on Gmail on Firefox as well as Gmail & Outlook 365 on Chrome. Any help is appreciated.

OK I just updated to Firefox 99 and now my shortcut opens the browser and places it in the task bar it is not displayed on the full screen

I am real fed up with this clown camp not that you care Will try to reverse update not sure how to do that

From the last weeks, I have some issues with my Firefox. I have tabs crash with "oops, the tab crashed.." (like my screen but it's in french). If I let a video or a stream for example after 10 or 40minutes I can have this kind of crash.

Do you have any idea of the origins of this problem ? Thanks !

I usually have Firefox open for 8 hours a day (open Firefox in the morning and close it in the afternoon). About once a week I'll notice that at some point during the day Firefox will just stop loading new websites. Existing sites will continue to function, and requests to those existing domains work. But new sites, that I didn't already have open, won't load at all; the tab will just sit there, thinking indefinitely (no errors).

When it does this I will try microsoft.com or google.com to check and make sure it isn't just the site, but those won't load either. I'll try it with a Private Window as well to the same effect (private window has no extensions enabled). Chrome/Edge still work fine during this. In order to get Firefox working again, I have to close Firefox and then usually force quit the process instances (or wait a long time for it to reopen on its own). Once reopened everything is back to normal and all sites load as normal.

I think this happens when Firefox loads a new update in the background. I've noticed on more than one occasion this behavior has coincided with a new Firefox version. In fact it just did it again (prompting this post) and when I got Firefox back open again it had a new update tab displayed. So I'm fairly sure it is the background updates causing this.

This behavior has been happening for a very long time. At least 6 months. Across many Firefox updates.

I have a separate Firefox profile that I load using a separate shortcut (with the -P property). When this behavior happens it often impacts both instances of Firefox. Not sure if this bug is related to having multiple profiles or not.

Windows 10 64-bit

For the last two days and multiple times loading the firefox browser, it has taken about five minutes for the browser to load on our Dell Inspiron desktop, running Windows 11. Nothing happens for about one minute, then the spinning blue circle appears, then firefox starts to load, then the screen goes back to the desktop, then a black screen appears, then some white rectangles start to appear across the top of the screen, then the screen goes back to desktop, then back to the black and white top-of-browser window that is still trying to load, and then finally after the five minutes, our home page loads. However, clicking on a bookmarked website, or typing in a website in the address bar results in a 2-3 minute wait for that site to load. And this happens time after time with the computer still on, and also startup after startup. If this should continue for a few more days, we will start using Google Chrome or Microsoft Edge, and also cancel our subscription to Mozilla VPN. This cannot continue!

As of last week, I am unable to reply in the reply sidebar in a Slack thread. When I click the reply icon associated with a comment, the sidebar opens and a loading icon is displayed for a second but then nothing happens; all I get is a white sidebar. I have updated to 99, shutdown and rebooted, opened Slack in an new window and nothing allows replys. I am running Windows 10 Pro, build 1903, 64 bit, i5 processor, 16 GB RAM. Suggestions?
