I have the same problem https://support.mozilla.org/en-US/questions/1421734 it's not a pdf. If I want to print a shipping label from eBay using Firefox nothing happens if I try to make it bigger. I can make it smaller but it is too small to begin with. If I use Brave or Edge (using the same printer) it works I can adjust it and make it bigger up to 200 %. I have already reset the printer options in Firefox and tried when disabling all add-ons.

I have not updated firefox in a while, but recently got an error on netflix that my browser was no longer compatible and to update

So I updated to the latest version of firefox - 122.01 (64-bit) but now I have a new problem. I cannot watch anything on netflix or hulu (though I can on max for some reason).

Each time I try to play anything on netflix I get a white screen on firefox and it automatically takes me back to the sign in page of netflix. Each time I try to play anything on hulu it plays BUT I cannot see the video. I can hear it but the actual video isn't shown, the controls are there but I can only see the the menu/other things to watch of hulu (picture attached) though I can't actually click on any of the other shows

I do not have this problem on chrome but firefox is my main browser, can i get any assitance Things I have already tried: I completely cleared my history & cache after signing out of everything (did this twice). Turned off computer, signed back in but still have this issue

I just installed FireFox but keep getting Chrome browser. How do I set FireFox as my default browser? My bookmark tab icons keep changing - how to change them back permanently ?

Dear Sir/Madam

I have set up a new Microsoft Surface pro 7 with fresh Win11 23h2 and office installation.

The latest Firefox 122.0.1 has been downloaded.

Problem:

When i sign in to my Microsoft 365 account for the first time everything goes smooth and get all authentication steps.

BUT

1. I never reach the Microsoft 365 page and return back to Microsoft log in page

"https://www.office.com/?trysignin=0"

2. if I insist in Trying I get in a loop and i get the error message "AADSTS50196 authentication error,"

3. I have tried to clean Cookies cash. The only difference now is that i do not get in that indefinite loop but i have to reenter the sign in credentials and again reach the log in screen.

4. I have entered the office.com, Microsoft.com, hotmail.com as trusted sites but problem same

5. No issues in that particular Surface pro to sign in Microsoft 365 site via edge

6. No issues to sign in Microsoft 365 in my other computers via Mozila. It happens to that particular surface new installation

Any help/Troubleshooting will be appreciated

When the system theme (light/dark) is switched globally, Firefox recognizes this and also switches its theme automatically (if configured appropriately). This should also retheme addons opened in the sidebar (Tab Stash or Sidebery for instance), and it does so under certain conditions, namely if either a) no sidebar was opened when starting Firefox and the addon sidebar window is opened directly, or b) the sidebar was opened with start of Firefox. Unfortunately, no retheming of the addon window occurs when some other Firefox sidebar (such as bookmarks or history) was opened after Firefox start and before system theme switch. In that case, the addon window (which is opened as the system theme is switched) does not retheme. This can be mitigated by either restarting Firefox or by opening a Firefox sidebar such as bookmarks or history, and switching back to the addon window.

So to reproduce this behaviour:

1. Open Firefox and some sidebar addon directly (such as Tab Stash in my case, with Ctrl-Alt-S)
2. Switch system theme globally (I do this with Night Theme Switcher in GNOME)
3. Observe that Firefox correctly redraws the addon window
4. Open bookmarks (Ctrl-B) or history (Ctrl-H)
5. Reopen the addon window
6. Switch system theme globally again
7. Observe that Firefox does not correctly redraw the addon window
8. Open bookmarks (Ctrl-B) or history (Ctrl-H) again
9. Reopen the addon window
10. Observe that Firefox redrew the addon window

This has already been reported to the addon developer, who stated that it might be a bug in Firefox, since his addon only tells Firefox which colors to use in which mode.

System details:

• OS Version: Linux 6.7.4-arch1-1
• Browser Version: Firefox 122.0.1
• Desktop environment: GNOME

Hi,

What is the area above toolbox called (Firefox, File, Edit, View, History, Bookmarks, Tools, Window, Help) and how do I change color on just that?

Thank You, Leslie

I use a public computer often, and I would like to use certain customizations while remaining anonymous. Rather than going through and clicking a bunch of checkboxes, I decided to have a hot key combination to enter in order to obtain my desired options. For example, I want to allow new windows to open normally, I want to choose where files are saved, and I want to turn off Firefox's recommendations. The underlined hotkeys are, respectively, ALT+W, ALT+A, and ALT+R ALT+F. So rather than a bunch of scrolling and clicking, I could just type ALT+WARF, and get the options I want quickly.

However, pressing the hotkeys while in the settings does not seem to do anything. In particular, pressing ALT+WARF only succeeds in pressing the ALT+F, which opens the File menu. Pressing these keys without an ALT key sends them automatically to the search bar -- which is also not what I want. Pressing ALT+SHIFT focuses in on the checkbox -- but does not press it. For example, ALT+SHIFT+W focuses on the checkbox, but I still have to click SPACE after it to press it.

Is this a bug? If not, how can I make the underlined keys press the respective checkboxes?

Hello,

I've encountered a recurring issue with Firefox on Ubuntu where my master password is sporadically not recognized when typed using my external wireless keyboard. This problem does not occur consistently but is particularly frustrating when it does, as it forces me to switch to my laptop's keyboard for input. I'm certain the password is entered correctly; after multiple careful attempts (3-5 times), the issue persists, leading to unnecessary stress and inconvenience.

• • Environment:**

- **Operating System:** Latest version of Ubuntu - **Hardware:** Dell Latitude laptop with a Contour external wireless keyboard, connected through a Dell docking station. This setup is shared with another laptop (HP) via the docking station.

• • Observations:**

- The issue seems to occur sporadically and is not reproducible on demand, adding to the frustration. - It has happened notably on the first login attempt after the computer's first boot of the day. - On one occasion, the problem led me to change my master password under the mistaken belief it had been compromised.

• • Impact:**

This intermittent recognition issue disrupts my workflow and significantly affects my user experience with Firefox. The necessity to switch input methods and the initial misinterpretation of the problem as a security concern are particularly concerning.

I hope this detailed feedback assists in identifying and resolving the issue. Thank you for your attention to this matter Firefox.

Sincerely, Daniel

Currently, there appears to be only one option to tell Firefox to open a given site in a specific container; that is, from the URL bar, to the right.

Would it make sense to have this configuration option presented in "edit bookmark" and/or in a right-click pulldown menu "Always open in this container"?

i made a custom firefox colour setup for my desktop machine, and it doesn't have any option to save it- because of this, on my laptop which is synchronized to my desktop's firefox settings, it is not showing up at all and if i go to firefox colour it isn't there for me to add. so how do i DO this???

i do not want to maker my custom setup public so it is not available to all, it is my own setup using some of my own artwork which i do NOT want made public on the internet.

there MUST be a way to save it however and let my laptop's firefox also display it,m yes???

and on that topic, why isn't it just automatically synchronizing when everything else does?

Hi! Relaying this for another Firefox user. Whenever they go to Google Images, it seems like the images don't fully load. GIFs don't play, and it ends up showing the preview rather than the full image. This isn't happening on other sites like Bing. Any ideas what could be causing this? A uninstall and reinstall didn't help.

Thank you so much!

I can not log into my Harley ride planner account. Its not the websight as I can log in on my I phone. I get this message.The resource at “https://www.harley-davidson.com/etc/designs/h-d/images/dropdown-arrow-white-2.png” was blocked by OpaqueResponseBlocking. Reason: “nosniff is true and mimeType is an opaque-blocklisted MIME type or its essence is 'text/plain'”. How do I fix this? Thank you Paul

When you switch the language in a text field, the focus on that text field is lost and the focus goes to another browser tab. This only happens if at this time a video is playing in mozilla in picture in picture mode with the Always on top option enabled. How to fix it? (Ubuntu 22.04)

When I attempt to sign into my Amazon account my email is in the autofill box, so I press continue as instructed. The passward box displays a long line of dots that cover the entire box and will not let me enter a password or erase those dots. I have changed my password and that allows me to sign in to my account ONE TIME. The same thing occurs every time I try to sign in. The autofill is not working properly. If you will clear the autofill on my Amazon account I will enter a password.

Hello, Live videos in youtube are not starting. No issue with regular ones. Also FB reels don't have sound and I need to press two times on play to start the video.

I tried with Chrome and Edge and I don't have such issue.

I have no extensions or add-ons installed. Cache and data are cleared.

Could you please help me?
