Firefox Support Forum

Hello,

I deployed my NextJS app on Vercel, but I cannot access my deployed app through firefox because of HSTS.

I tried to access several sites with domain .vercel.app but the issue persists.

I can access all sites with ".vercel.app" domain just fine on other browsers except Mozilla Firefox.

I already looked for solution on the internet such as:

1. Removing entry on SiteSecurityServiceState.txt
2. Forget site
3. Clear browser cache & history
4. Restart browser

Any help will be appreciated.

Thank you for your time and attention.

Although I have disabled all relevant "sync" settings in Firefox, the browser is still syncing tabs across my MacBookAir and my iMac.

To make matters worse, tabs in Chrome and Safari sync to Firefox tabs across devices as well. The sync occurs in both directions.

I am not logged into Chrome or my gmail account.

Specs: MacBookAir: early 2015/ OS v. 12.7 (Monterey) iMac: Retina 4K, 21.5-inch, 2017 / OS 12.6.8 (Monterey)

Things I've tried:

• Turning off syncing in Firefox on both devices.
• Signing out of Firefox from both devices.
• Disabling "sync open tabs" via Firefox preferences
• Renaming devices from within Firefox Sync. (The name always reverts to the previous one.)
• Reinstalling Firefox
• Deleting cache from both Firefox and Chrome.
• Restarting

Images are from toolbar on iMac when Firefox is open on both computers. Any help would be most appreciated! Thanks!

I cannot hear anything from websites, YouTube for example when using FireFox. I have checked the Volume Mixer and there is sound except for FF tab

I can hear perfectly in other browsers so this problem only exists when using Firefox. I have tried all the suggested remedies with no success.

Any suggestions welcome

For a while Google Drive's cloud interface hasn't been able to show "information" about files, i.e. pictures, text, file-data. The fault is not present in Android, Chrome and Edge so it is not Google Drive that is buggy. I'd rather not change to another web browser. Please present a fix.

I have turned off all extensions, allowed all permissions on the page, changed the Privacy to Standard, turned off enhanced protection, but I still cannot get the popup to show on this page (need login to see actual page)

I cannot find anything else which can be blocking it, but something is.

If I load the page in Edge, it works fine.

I have used Firefox since forever, was a Netscape user in the past

But for about 3 months Firefox simply is no good anymore\

It is more and more sites I can not access with Firefox and have to use Edge instead.

Last example, just now

See screens attached

This is just one example, many other sites simply do not open, or open properly, in Firefox

WHAT IS HAPPENING?

Thank you

as of 2023/09/29 hulu, netflix, prime and disney+ are not playing videos on firefox, after making zero changes to settings or configuration.

I tested Netflix on Google Chrome and videos played, confirming this is a Firefox issue. I cleared recent/all history and changed passwords for those sites. Netflix logs me out if I attempt to play content. Speedtest reports 200 mb/s. Mozilla VPN is installed but turned off. Netflix sign in reports a new device/login in my state which is different from the VPN setting so this confirms that the VPN is not active and blocking content. HBO/Max videos play correctly and that site does not have the same issues. Firefox has crashed numerous times in the last two weeks. Sometimes just a single tab, sometimes a full application insta-quit.

I prefer to compartmentalize usage across different browsers for privacy/security reasons and would like to continue to use Firefox for these streaming services.

Up through Monday, 10-16-2023, I could play Amazon Prime Videos. As of Tuesday, 10-17, I no longer can. I can do this on other browsers, e.g. Chrome and Safari. Can this be fixed or do I need to stop using Firefox?

hello I cannot turn off Firefox Fullpage Translation, which is really annoying. When I browse I get asked for every new page in which language I want to translate and I don't want to. The translations are mostly bad and I know in which languages I browse and research. I haven't been able to find how to turn it completely off in the settings. Can anyone help? It'd be great, thanks.

i would like to increase the no of columns for TopSites in newTab page to more than 8 columns.

there is a method to increase the no. of rows but since my monitor is wide I would like to have increased no. of columns which will let me to view all the topSites in a single page without any scrolling.

Is there any property that can be added in the about:config page to increase the no. of columns.

Hi all,

Apple has revised/updated their iCloud web portal. The backspace key no longer registers in the iCloud Calendar app on the web. This is specific to Firefox on Windows - I've tried other web browsers to access iCloud web portal and Chrome's backspace key registers so its not an Apple iCloud problem, just Firefox. Is there a setting or do I have to wait for an update?

Thanks in advance.

About three days ago, the dropdown lists for various websites I use stopped populating unless I use the backspace. So, for instance, if I want to find "John", nothing happens if I just start to type it in. But if I type in "Jo" and then backspace, John pops up. (Perhaps important: Even though I have now deleted the "o", only John pops up, not names beginning with J but followed by a different letter.) Curiously, it seems like the first time each day that I go onto any given website, the dropdown does populate properly, but just that once. I checked Edge and Chrome, and the dropdowns work fine there, so it's definitely a Firefox problem. Any ideas about what is going on and how I can fix it? Thanks.

A few months ago, an automatic feature in bookmarks quit working. It used to be that when you bookmarked a page you would be prompted about what bookmarks folder you wanted to put it in. That suddenly quit working. Now, after you bookmark a page, you have to go into "Manage Bookmarks" then move it to the folder you want. I can't find a setting that would bring that back. Was this a change that was deliberately made in an update or is it just a glitch that happened somewhere along the line? If that feature was removed, I'd like to know why. It doesn't make sense.

Firefox won't show ever the window to save files or to open files. It happens on any website. If I press ctrl+S the "save as" window does not appear. If I try, on any page, to open a file for upload the window to select the file does not show.

Please advise!

I need to know where I can find the Content Process Limiting Setting in Firefox, it's gone, or is not where it is said to be located. This is the instruction I found. "uncheck the Use recommended performance settings checkbox to enable some hidden settings. One of those settings is the Content process limit setting, which can be set to a number between 1 and 8"

Its using up to much memory on my already slow processor.  

Please help me stop the extra processes.

I prefer to have all my previous tabs open when I start up Firefox, which means that I don't want them to close upon exit. Recently, Firefox started closing my tabs upon exit, even though:

- I tried both hitting the X and choosing Exit from the hamburger menu
- I have checked "Open previous windows and tabs" upon startup in settings
- I have not checked "Delete Cookies and Site Settings when Firefox is closed"

- I have the option "Firefox will remember history" selected

- I do not open in Private Browsing mode

What other settings do I need to change? Debra

My potato pc(amd A8-7600, 8G ram, rx560 2G) is not capable of YouTube vp9 hardware acceleration, but I played 1080p 60fps videos without difficulty using add-ons that force h264 decoding, but the videos started stuttering a while ago. At first, I thought it was add-ons problem, but other than YouTube, too

I used the translation app because I was not good at English

Dear all, I have unchecked all the boxes in "Settings/Search/Search Suggestions" and disabled history for the search engine and yet Firefox still displays search suggestions in the address bar. They even have a small header called "Firefox Suggest". How can I turn this off? Thanks for your help, Markus

Per version 118 we now have the possibility to have webpages to be automatically translated from its original language to another one. As end user I get prompted for every page I visit whether I would like that to be translated. This is quite the flow-stopper. I have no need nor interest for this amazing functionality. However, I can't find anywhere an explanation on how to disable that functionality. I would appreciate it if I was not prompted for this translation possibillty. My question: how to disable this translation functionality alltogether? (I.e. How to stop Firefox asking me about it?)

Currently i found the configuration for opening in the same tab, and that middle mouse will open a new tab. However, the new tab from middle mousing, just opens the same tab as where I middle moused. It does not appear to be loading/opening the link I clicked. Ive tried a few items in about:config but havent found one that makes it load the middle moused link.
