While browsing youtube,i no longer find cast to tv icon in Firefox browser.Can you help me please,as after stroke my eye-sight is diminished.I was able to do it before,as i switched over Linux Mint 22 wilma,i am unable to find this cast icon.Thanks.

i need to copy and paste text that's also a link, but firefox isn't letting me highlight it, I can do it in chrome, brave, & opera, it's not a mouse problem either, if I just right click on the page and select "highlight all" FF wont highlight it, is there a setting for this or a extension I can download? (in the picture the the rad text is also a link, I need to copy the number portion)

The new native tab group feature has an option to "Save and close group", implying that you can restore the group. But doing this, you will find that the group disappears.

Is this a known bug? Has anyone figured out how to restore a saved tab group?

Hello,

For a few days now I've been unable to use Google tools via Firefox (I can't tell if this is due to an update or not).

As soon as a document (usually an editable or navigable area) is opened on the page, it appears completely black. Interactions work correctly at first glance (it's possible to click, write, interact with content that isn't displayed. The problem seems to be purely visual.

I've encountered the problem in all Google Sheet or Docs documents (including when I'm making a new one) and on Google Maps, regardless of location (in the case of Google maps, a notable point is that the map is displayed and then turns black after one or two seconds).

I don't have this problem on another browser, I have it in PM.

Do you have any ideas on how to find the cause and fix the problem?

Have a nice day!

Dear Sir,

Firefox is not working with Rabby Wallet and Metamask extensions.

It does no pop-up the window to see the transaction and sign it. Firefox 134.0.1 (64-bit). Windows 10 Home.

On Metamask at least I can click on the pinned extension and see the window. However it´s not the expected behavior, because it should open the pop-up automatically. With Rabby wallet it is impossible to proceed, even clicking on the extension icon.

Please fix it.

Hello,

Suddenly some UI elements became color-inverted or almost completely black, such as the tab icons in the tab bar, the website icons on the New Tab page and some icons in the settings menu. Also, some websites appear to have this issue, but the Samsung website is the only one I found so far with this issue.

On the same day it happened I switched to an OLED HDR-capable monitor, so I assumed it would be related to HDR, but I played around with some settings and I'm not sure anymore.

What I tried: - hardware acceleration on and off - HDR completely on and off - default light theme and dark theme, no customs themes installed - all extensions disabled (I have no extensions that would influence graphics or colors anyways) - latest update already installed - nothing else changed in the Nvidia control panel as far as I remember

None of the above helped. Any advice on this is appreciated. Attaching some pictures with the issue. Using Windows 11.

Thank you!

To whom it may concern,

I have an angular application accessing data from a 3rd party data provider. To get data, POST-requests are sent to the data provider REST API (https://capzlog.aero). The application works correctly using Google Chrome and Microsoft Edge. However, when using Firefox, the following error appears:

"Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://capzlog.aero/api/pel/public/externalsystemflights/GetMissingIDs. (Reason: CORS request did not succeed). Status code: (null)."

As the POST request contains basic authentication, a preflight-request (OPTIONS) is first sent to the data provider. This request fails when using Firefox (but not when using Chrome or Edge), see attached screen-shots.

I have spent 4 days on the internet trying to figure out a solution, but I could not solve the issue. I tried the following: 1) check the certificates of the 3rd party provider (https://capzlog.aero): There are no issues. 2) start Firefox in safe-mode, disactivating the "Enhanced Tracking Protecting", clearing the cache. 3) changing the following Firefox settings:

   security.enterprise_roots.enabled (true<->false)
   security.tls.version.min (1<->3)
   security.tls.version.max (2<->4)
   network.http.network-changed.timeout

I tried sending the "OPTIONS"-request using curl and it worked as expected:

curl --verbose -XOPTIONS -H "Access-Control-Request-Method: POST" -H "Origin: https://projectz.numericalsolutions.ch" https://capzlog.aero/api/pel/public/externalsystemflights/GetMissingIDs

I really do not know what to do anymore to solve that problem.

As the problem is impacting hundreds of users, I really hope there is a solution.

In advance thanks for your help.

Greetings all, my trusty Firefox stopped working. Error Code PR_Connect_reset_error. Other browsers work fine. I have windows 10 with the latest updates and use Kaspersky Internet Security 21.3.10.391 (m). I have paused Kaspersky, uninstalled then reinstalled Firefox 3 times. I have cleared all Firefox cookies and caches a number of times. On my 2nd Firefox reinstallation Firefox worked ok for a couple of times then stopped again with the same error code. Please note that I am not very familiar with computer stuff so any suggestions need baby steps. Many thanks.

So I understand this: https://support.mozilla.org/en-US/kb/xframe-neterror-page and the reason it exists, but I need to find a way to turn it off because it's literally blocking me from accessing the Library of Congress webpage inside the same browser for my job. It's not a malicious site, but I can't figure out how to tell Firefox to stop blocking it as if it was a malicious site.

Help.

I've freshly reinstalled Windows 11 and after trying to access and watch a movie on any of these sites I get an error (see the pictures).

Browser version: 137.0.1 (64 bit) Widevine version: 4.10.2891.0

Already tried to disable/enable DRM. Already reinstalled firefox. Already manually installed widevine. No clue what could be causing this issue.

I use Primary Passwords on important sites. Since v136 installed this morning, no matter what site I OPEN Firefox to, even search sites, the Primary Password is requested. If Firefox is already opened, if I open the "unimportant" site, no password is requested.

I have updated to the latest Firefox version for the Android app, using Samsung Galaxy S20. When viewing YouTube in mobile view (desktop view works though) through the browser, the comment section seem to be invisible and not showing. I have tried fresh reinstalling, and toggled all the settings, but I can't seem to get it to work on Firefox. Other browsers like chrome works just fine. Is this a bug?

I have Firefox's New Tab set as my home page, since I'm choosing to divorce myself from political doomscrolling for the next four years. The New Tab page is perfect for having frequently visited sites at the top, Pocket stories I can curate in the middle, and what used to be a history of articles and sites I've read most recently in "Recent Activity" along the bottom. Within the last few days, "Recent Activity" has been blank, and will no longer keep track of articles I've recently read. I've tried clearing the browser history and cookies, and it came back for a moment, but quickly went back to being blank. And the major downside to clearing the browser is that my four rows of most frequently visited sites gets wiped clean also, and I have to spend time getting them back on the list. I do not have Firefox set to automatically clear history upon closing it. I've tried turning "Recent Activity" off and on with the page's Settings (cog in the bottom right corner). I'd really like to have this back, as it can help me find recently read content (especially Pocket content) easier than wading through the History log. Any help would be appreciated.

For the past week now, every time I go to this link https://marketplace.secondlife.com/ , it is in another language. Usually Spanish or Portuguese and now and then French. I'm always having to translate. Even though my settings says English and i have no other options.

I use the IRS form filler to pay my taxes...have for years with Firefox browser. This year (for 2024 return) when I sign into the site the 1040 form does not display correctly. the boxes are to the right and below the actual placement. I emailed IRS who said it is a setting in Firefox. I tried the site using Microsoft EDGE and it displays correctly. I have searched for possible solutions and tried them all like using/on and off excelerator, letting Firefox chose size and colors of sites, turned off Noton etc. I posted another question here but no replies or looks so maybe I did something wrong so I will try to post again. I have W10 fully updated and Firefox too up to date. I understand I could use Edge but never had to and prefer to use Firefox as I have before. any suggestions would be appreciated or where I can report a possible issue with Firefox. I have attached a sample. thank You
