Firefox Support Forum

In seeking a way to reduce the CPU & RAM usage, I read that perhaps turning on the Hardware Acceleration might help. And to do that, you must first de-select the default setting which says FF will use the best settings for my computer. Well, when I opened that section, neither one was checked! So, should I first try the default setting, and if that doesn't help, then try HA? I'd always heard not to use HA, for some reason, but I'm ready for trying anything that might help use less resources, and open webpages more consistently.

Which is the best setting to use, or neither one?

Using Mac OS 10.13.6, Firefox recently updated to 115.0.3, and now the Overdrive app (from the public library) won't download audiobook files anymore. Have tried clearing cache, restarting, removing book files, restarting, and reloading the OD app, etc. The error message is that the app can't connect to the internet. My internet connection is fine - this is only happening with this app. It only started doing this when Firefox updated. I tried loading an earlier version of Firefox but it automatically went to this Beta update channel version. Can you help me go back to an earlier version of Firefox that won't automatically update? (I'm not able to upgrade this Mac, and this OS is the one that Overdrive works with. Firefox was the only browser that worked with Overdrive. Thanks - hope you can help!

Hello, I've been experiencing constant tab crashes in Firefox and Edge. Trying to figure out if anyone can help me pinpoint the cause through Firefox reports. Links are below. Thank you!

Hi, the site "https://pixabay.com/" is suddently extremely slow with mozilla. The pictures don't showup or take many minutes before you can see them. Normally only white boxes show. The same site (pixabay) with the browser "Opera" works perfectly. I always use mozilla and since a short while it just doesn't work with pixabay (a site for royalty-free images). Can you please fix it? Thanks. Regards Elisabeth

Pretty much every video I attempt to play, including https://www.allaboutbirds.org/cams/red-tailed-hawks/# will play the video only when audio is muted. unmute the audio and you get the audio track but the video is paused.

Can't figure this one out, I've seen it only in the last few days (it started when I was using 127.0.0 and continues in 127.0.1)

Chrome and Chromium don't do this.

Thanks in advance for any helpful advice!

Suppose that I have a 5 kbyte comment with multiple paragraphs, and I skip around copy and pasting from one place to another, and highlight some sentences and over write them either with typing or pasting. When I go to undo or redo some of these things, it causes a big screw-up in the text.

Other than it being my problem to recompose the damaged sentences, etc, what developers need to be contacted to fix the undo and redo functions of the YouTube comment input text controls for YouTube videos?

Dear friends,

I have Firefox Browser 127.0 (64-bit) installed. IFRAME is not displayed on some websites.

Example: https://www.rollerfreunde-untermain.de/gaeste.htm

Attached you will find a screen shot.

Can anyone say why this is the case?

Kind regards Uwe

I have a very good PC (5800X3D, 7900XT, 32GB DDR4 3600), but Firefox (either the normal, canary and nightly version) can't play smoothly any 4K video (like the Borderlands trailer: https://www.youtube.com/watch?v=lU_NKNZljoQ ). 1440 and lower resolutions are fine, as are 4K videos on Chrome and Edge. FWIW, my CPU during 4K playback is barely used (1-2%), and my GPU's video codec (VCE) is used by around a third. Disabling HW accel makes things better, as it still stutters but it's (barely) passable. I already tried creating a new profile, but still it's the same.

Firefox on Windows 10 desk top suddenly stopped working with error message

XUL Runner Error. platform version 127.0.1 not compatible with Min version >= 127.0 Max version <=127.0

N.B. This is another machine - not this lap top

Please advise

Hi,

For some time now, when I download a .pptx, .xlsx og .docx Firefox changes the file format to .pdf when downloading the file. I then have to manually choose the correct app for opening the file, overrule error messages and delete the ".pdf" when re-saving the file even though it recognises it is not really a pdf file.

I've tried to change the Firefox settings, clearing cache, restarting or deleting in config and other small attempts to reboot whatever suddenly started to cause this problem. As far as I can see, it is not an unknown issue, but I've not yet been able to find a solution to my problem, which is getting on my nerves.

Hope you can be of help.

I would like to use Firefox as a browser on my Linux Mint device. As I said in the headline, I have set all languages in the system as well as in Firefox to German and uninstalled and reinstalled the dictionary. So when I write something in Firefox it is underlined in red and when I right click for the context menu where word suggestions are made, only English is displayed and if I then scroll down and want to add another language as a spell checker, Firefox sends me to the add-on administration, which didn't help me. Because no matter what I do, only English (USA) is displayed as the language for spelling. Is there perhaps no way to change this, or is there another method?

Many thanks in advance.

FF just updated to 127. Every time I open it I get the whole intro shebang about migrating, extensions, etc. When I finally get to "Start Browsing" none of my tabs or bookmarks will load. I have cleared the cache, tried reinstall and no change. What's next, please?

TIA Toby

Dear Support Team,

After updating to last Mozilla Firefox version (126.0.1) all my ngx-datatable tables are overlapping all rows over the first one even if the entire height of the table is correct calculated.

This is a blocking point. I need assistance urgently.

Im using Ubuntu 22.04 LTS Intel cpu I7 9th gen NVIDIA gpu but i disabled it My problem is that the Picture in Picture mode isnt sticky if i press anything it vanishes from view.

I have used Firefox to access my Zoom accoutnfor several years. Today, the screen goes blank when I click on sign-in. This does not happen with other browsers on my PC. Help....

I have had some issues using Firefox and I was told that the website works better with Google Chrome by a support person. For the last recent issue, I was told a website doesn't work correctly basically with Firefox and that I needed to use Google Chrome or Edge. I recently received an email from Mozilla which had a link to an article titled, "Here’s what we’re working on in Firefox" at: link text and in the article in large print it says, "Bringing you the features you’ve been asking for." I didn't see any mention about increasing Firefox's compatibility with websites.

Hopefully, somehow comparability with websites will be made better.

When I try to play a video on Firefox desktop, it takes it a long time to load. Once it has loaded, whenever I pause it for more than a few seconds, or if I try to skip around the video (either by clicking around in the loaded section of the progress bar or using +/- seconds buttons), the video begins buffering again before the video resumes. This makes it extremely difficult and frustrating to watch anything that requires me to pause, rewind, or fast forward. I've noticed this issue affect multiple video viewing sites, such as YouTube, Vimeo, and Netflix. My roommate also uses Firefox, but doesn't have this issue, so I know it's not a problem with my internet. I thought it might be a problem with my computer, but I tried to replicate the issue in Chrome and everything worked fine there. The issue has persisted almost a week. I have:

• Rebooted my computer several times
• Deleted my history/cache
• Disabled my extensions
• Turned off Java scripts in firefox (this disabled my ability to load sites like YouTube completely, so I turned it back on)
• Updated my computer
• Updated my graphics drivers
• Refreshed firefox
• Uninstalled and reinstalled firefox (and rebooted my computer)
• Uninstalled and reinstalled firefox AND deleted all the data it stored on my computer (and rebooted my computer)

I am currently using version 123.0.1 of Firefox. My OS is Windows 10 22H2.
