Tab detachment was working fine until updating to Firefox 126. Now the tabs cannot be moved, detached or dragged to another window.

In about:config, browser.tabs.allowTabDetach is set to true

Suggestions?

YouTube content doesn't load. Same with NYTimes.com articles.

Up to date, no extensions, no add-ons.

Running Sonoma 14.4.1

Safari and Chrome work as expected.

I have restarted and updated both firefox and my computer and disabled all of my security extensions for Canvas. However I still do not have any content loading for assignments or quizzes.

I was browsing a webpage that turned out to be in Portuguese, and I was looking for how to translate it, but the internet indicated that Firefox has built in transation! However, neither the Translate Toolbar Icon nor the Translate menu option appear, even if I visit a site that absolutely should be translatable (https://fr.wikipedia.org/wiki/Mozilla_Firefox)

Additionally, if I go to Settings -> General, there is a Translations section, but if I click the Settings button, there are no languages in any of the boxes and no option to add any.

I am on Firefox 126.0 for Windows.

Here are the things I have tried:

• Restarting Firefox
• Rebooting my PC
• Disabling all my extensions
• Running Firefox in Troubleshooting Mode
• Clearing my Startup Cache
• Performing a "Refresh Firefox"
• Toggling and Untoggling browser.translations.enable and browser.translations.automaticallyPopup

Does anyone have any suggestions of something I could have missed?

I am forced to switch over to the browser Brave, have been a true Firefox supporter but am unable to change the background from dark back to light, this has nothing to do with the computer desktop settings since Brave, Edge and Google Chrome all are still running with the light background. Please help since I find this unacceptable, have problems reading with the dark background. Regards, Art.

After updating to the current version of my OS(listed below) I can no longer drag a tab to detach it from the firefox window. Doing so drags a preview of the tab, but it is never separated from the current window. I can drag it to an already existing window to move tabs from one window to another, but not to create a new window from a single tab.

the email used for FireFox - glennww@cox.net was transferred to Yahoo. I can not seem to download emails sent to this email address into Firefox as I was able to do prior to shifting to Yahoo. I went in and changed the password to the new password and to the new POP server (pop.mail.yahoo.com) but emails can not be retrieved. What am I doing wrong. I deleted the email account glennww@cox.net and tried to re-install as a new account, but it was not accepted. I don't know where to go

I've used Weebly for website building for many years. After the latest Firefox upgrade, the Weebly editor display labels are overwritten with other text, as in the attached images. I've checked on Chrome, Safari and Vivaldi browsers, none of which have the same problem. Opening in safe mode has the same effect.

Hello,

I am trying to remove a profile from Firefox and this message is above the profile I want to delete.

This profile is in use in another application and it cannot be deleted.

I have searched the Mozilla support site and can't figure out what application is using that profile.

I'm using: Macbook Pro Mac OS Sonoma 14.0 Firefox v 126.0 (64-bit)

Please help! Thank you! Jordan

Whenever I use the picture in picture feature, it always opens up in a bigger tab instead of the floating PiP. I am unable to adjust the sizing whatsoever. Is there a way to get around that?

For a very long time I have been using Afterpay successfully through Firefox. Since the last update of Firefox a few days ago, Afterpay has been failing to complete transactions. This has occurred on 3 different sites. I contacted Afterpay and it appears everything is fine on their side. This morning, after another failure, I tried the same transaction through Chrome and it was successful. Paypal still works with Firefox without a problem but it seems there is a transaction glitch between Afterpay and this updated version of Firefox.

Earlier I tried to open firefox to go on the net and Bing came up. I uninstalled Firefox and reinstalled and the same happened. Then I deleted the Firefox folder fron the hard drive and then reinstalled Firefox again. This time it opened correctly. I can only assume but don't know, the Bing thing came about through one on the windows 11 updates. How can I stop this from re-occuring or can I? I only ever use Firefox, its just the best, thank you.

PS: I did have Firefox as my default browser but Firefox still became Bing. Lis

Firefox's website appearance settings include a setting to force a light theme, force a dark theme, or to have sites automatically adapt to the theme of the browser. I feel that's not exactly what I want. I don't want the browser's theme to have anything to do with themes of the sites I'm viewing, nor to force light or dark. I think I'd rather just use the site's default, or if not that, set a theme on the site itself. Is there any way for Firefox to just not meddle in a site's theming at all?

I kinda just don't want any connection between the theme of my operating system, the theme of my browser, or either of those and the theme of websites, and none to force a theme on any of the others. I'm not sure why that seems so desirable nowadays, but I don't want it.

Trying to recover from a hard drive crash. Had to buy a new desktop with Windows 11 Pro (looking to be a bad move). I downloaded/updated to Firefox 126.0 (maybe also looking to be a bad move).

Have my last "working" userChrome file (it took me weeks to perfect this to my needs).

I am looking for: C:\Users\<user>\AppData\Roaming\Mozilla\Firefox\Profiles\<profile>\

but there is no "AppData" folder. And there is no existing userChrome.css file, anywhere!

Is the functionality I am looking for a thing of the past?

Is Firefox not completely supported by Windows 11?

If so, what is the last version of Firefox that will still support userChrome.css?

Firefox only offers seven filetypes for handling (open or save the file). How can I enter more, for example what to do with an xlsx file? I want Excel to open the file, not download it.

I have been using Firefox for many years and never had issues. Two days ago, I turned on my HP with Windows 10 and I got a pop up message something about Error Platform 126.0 XUL Runner is not compatible. I could not access Firefox, Google, or the internet. I uninstalled Firefox and reinstalled, but after that, everything runs very slow. Each time I go into a website, it can take up to over a minute to pull up! I cannot even delete email from my Gmail! It's piling up. Downloading can take over an hour! I checked all the trouble shooting forums in Mozilla and tried just about everything. I went back into "About:profile"s and created a new profile. It it did not make any difference. I also did a Firefox refresh. Did not help any. I went back into the profile I had before the XUL error because my bookmarks were there. Still slow. I cleaned out the cache, in both Firefox and my Windows 10. made no difference. I only have three extensions in Firefox. I don't know what else I can do to fix this. Also, my drivers and other software are automatically updated by Windows. My HP is only 2 years old as well. Everything was fine in Firefox until that XUL error message popped up and I had to uninstall and reinstall Firefox. That is when everything became agonizingly slow!

Update: My computer is barely usable anymore because of the Firefox issue. Having to wait for a minute or more for everything I do on the internet? I know it cannot be my computer itself because it is not even two years old yet. I may have to dump Firefox if I cannot get this fixed. I have Norton 360 and it is not malware or a virus. Firefox messed something up.

whenever I am filling out an online form that requires basic info, Firefox prompts the common info that I have input in the past via the Auto-fill feature. Whenever I click on the suggested information, a new settings tab opens and switches my screen view to that tab. This didn't happen prior to the most recent update and has made filling out various forms extremely tedious and frustrating.
