I can no longer view YouTube videos in Firefox browser because they think I have some kind of add blocker installed. I have never installed such a thing and have no idea how to fix what they are demanding I must fix in order to continue with YouTube in the FireFox browser. In the mean time I have to use some other unfamiliar browser just for YouTube. It appears that some kind of incompatibility has evolved in the recent two or three weeks between Firefox and YouTube.

Firefox cannot play IMDB video. It shows: This video file cannot be played error code 224002 Youtube and other video contents are working fine but IMDB. Chrome and other browsers are playing IMDB video without any issue. Why Firefox does not? Is there anyone who knows how could I solve this problem?

Thank you!

I don't know why the page https://encuestas.msssi.gob.es/limesurvey/index.php/438579?lang=es is marked as insecure in Firefox. I tried in Chrome, Edge, IE... and the page is marked as secure, the certificate is recognized.

I attach screen captures of Firefox and Edge examples.

I've the security.enterprise_roots.enabled setting enabled.

If I check for Firefox error details, I see (auto-translated to english): https://encuestas.msssi.gob.es/limesurvey/index.php/438579?lang=es The issuer of the other end's certificate is not recognized. Strict HTTP transport security: false Setting HTTP public keys: false

I have been using the Walgreens web site to manage my many prescriptions without problems. Now, most of the Walgreens web site still works but the two menu options that need to display my personal prescription details fail with the display "Sorry, an unexpected error occurred. Please try again later." I initially thought that a Walgreens update might be in progress so just waited. Walgreens support gave me the same answer that there was probably web site maintenance in progress. After 4 days of the same problem and answer, I ported enough information to login in to Walgreens with the Microsoft Edge browser and access to my prescription information worked without a problem. I believe this problem with Firefox started around the time I updated to 117.0.1 but I might not have this perfectly correct. I was just notified to update to 118.0 and did so. Firefox access still fails and Edge access still works. Thanks for any help you can provide. Windows 10

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 was uninstalling another app when I noticed that there are two application icons for Firefox, one dated 3/25 2023 and one dated 9/26/2023 (just installed new update). How do I get rid of the first application dated 3/25/2023?

When I have Firefox minimized (with several tabs) and I click on its icon in the taskbar, FF does not immediately open, but little icons for each of the FF tabs show and I have to choose one of the tabs before FF fully opens. This is very annoying. If the program were to fully open, the one tab I was recently using would open and I could continue with my work. Is there any way to make FF fully open when I click on the FF icon in the taskbar? I am using FF 118.0 (64 bit) in Windows 11. Thanks for your help. Jerry

PS: the icon below shows what happens when I am clicking the FF icon and shows the two tabs open in FF.

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.

https://support.mozilla.org/en-US/kb/website-translation how can i disable this?

If I have a firefox window open (one or more), exit it, and start again, I can restore the previous session. However, if in between I open private browsing, it for some reason overwrides the session restore history with nothing. Can I somehow a) restore the session afterwards? b) prevent this from happening in the future?

With the new 118 version that introduced fullpage translations, whenever I got to a site that's not in English and that is one of the supported languages, the translation icon doesn't appear at all in the address bar. I can go to the menu and click "Translate Page..." and then the icon will appear but when I click to "Show original" it dissapears.

How do I turn off web translation permanently for ALL pages in Firefox 118.0.1?? It´s the most annoying feature so far from Firefox. Even if I delete all languages in preferences, it shows up on every page I visit.

When I select in Settings>Privacy & Security>History, that a history should never be saved and close the Settings tab, the next time I go to Settings, the option is replaced by the setting, that saves a history according to customisation and there's a check mark to always use the Private Mode. Apparently Firefox doesn't keep or save the setting. I learned from https://support.mozilla.org/de/kb/privater-modus that saving a history according to customisation with the option to always use the Private Mode enabled, is the same as never saving a history, nevertheless it should be possible to keep the setting (as the setting exists). How can I solve the problem?

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.

I was just updated to version 118.0.1 which is advertised to contain a webpage translation function. I clicked the show me button which sent me to the Firefox Mexico webpage. However, there's no Translate button/icon in the address bar. I've verified I'm running version 118.0.1 and have rebooted the computer. Still no Translate function observed. Any ideas?

Thanks, Mike P

Hello.

I'm using Firefox on windows 11 home 22H2. After the recent update to 118.0 I've been unable to load yahoo.com.

I tried the following: Disabled addons Disabled firewall Restarted firefox Restarted computer Restarted firefox in troubleshoot mode

I'm out of ideas except for a downgrade maybe.

Does anyone have any suggestions?

Since the latest download one of my 3 win10 PC's is displaying icons on top of the text. Firefox is up to date at Ver 118.0.1 (64-bit) I expect its a setting but I cannot find it. Screenshot attached. TIA KR's Andy B

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.

Hello, what's wrong with the bookmarks thumbnails, that they don't display properly (not as the site's logo), only some default ones that look ugly. Only some tabs have thumbnails. I have freshly installed firefox on a new PC and I've been using it for another day and nothing changes, I visit these websites constantly and these icons still look like this. It will stay like this or is it some browser error ?

Greetings

Tom

There used to be a solution via userChrome.css:

/* separate stop and reload buttons */

1. reload-button, #stop-button {

 display: -moz-box !important;

}

The above workaround no longer provides separate stop and reload buttons on the browser in the latest version of firefox.
