When you right-click on a window thumbnail, a menu should appear, but instead the window thumbnail just disappears. The screenshots show 1) a Firefox mini-window 2) a mini-window that just disappeared when you right-click 3) a mini-window of any other program 4) the menu that appeared is as it should be Otherwise the browser works absolutely fine for a long time. But this problem causes a lot of inconvenience because I have 2 monitors.

Die Handybilder(Android) werden beim Abspeichern auf PC oder Stick in Format PDF umgewandelt, sind verdreht und können am Panasonic Fernseher nicht angeschaut werden. (Format unbekannt) Wie kann ich das Umwandeln verhindern? Vielen Dank! Franz Schraut

Hi there, I'm trying to upload a new version of my browser extension (version 1.4.5), but the submission is being blocked due to a version number conflict. The issue is that I accidentally submitted a different extension under this listing with version 1.7.7. I reverted it immediately, but now I'm unable to upload the correct version (1.4.5) because it's considered a downgrade.

I really don't want to change my extension’s versioning just to get around this, since 1.4.5 is the actual next version in my release cycle. At the same time, I don’t want to stop updating the extension on the Mozilla Add-ons store. Is there a way to resolve this?

Hi- I'm trying to setup two step in Microsoft Authenticator. I scan in the QR code from the Mozilla settings and that appears to work. However when I copy the generated code from the app and try to enter it back into the settings in my browser it tells me the code is wrong and thus I can't setup two step. I've tried loads of different authenticator apps and none seem to work. Can you help please? Thanks- Adrian.

I have tried MANY times to make Firefox remain persistent as my browser. It appears I should log into an Administrative account to do so. Microsoft Edge appears to be the problem by remaining the default. I was told by the Tech Sprt for my Asus laptop to "delete" Edge. I entered the Administrative account using DOS. So many changes have taken place since I last used this account that I'm uncomfortable trying to take this approach. I was led to an administrative directory using "search" end while there was able to get a directory listing using DOS. But can't proceed. I really need the Windows pictorial version to proceed or technical support (preferred). Whoever helps must be fully capable.

Asus TS said I must delete MS Edge. The person seemed capable, but if I delete Edge, which I haven't found a way to do so safely, that may create problems but makes sense to do so because of the interference of MS Edge. My memory on how to proceed is that this process was MUCH less complex. I've read a number accounts by others with the same problem. My reasons for using Firefox, as an private engineer are to help prevent the stealing of intellectual property from wherever. Otherwise I'll have to abandon everything.

1. Whenever I open Firefox for the first time since boot, it crashes, and I have to click on it a second time for a window to actually show up. Once it shows up, it's forgotten all about the previous session - none of my tabs re-open, the window opens up maximized.

2. Whenever I close the last open window, my previous tabs are completely forgotten. Checking task manager reveals that there are 10 or 11 Firefox processes that are still running.

• I have a second Windows 11 device that DOESN'T exhibit any of these issues and works correctly. Closing Firefox does not leave any running processes around.
• "Open previous windows and tabs" is enabled in options.
• "Firefox will: Remember history" is set in the History options.
• Both devices are running Firefox 137.0.2 64 bit.

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.

Hello, I have Firefox set to open the tabs that I had open during my last session. (General > Startup > Open previous windows and tabs). When I open Firefox, it does give me all the tabs that were open in my last session. But it does not give me the current pages. It gives me the pages as they existed when I closed it.

Is there some way to have Firefox refresh the tabs when I open the browser? I seem to remember this happening in the past. But it's possible I was using a different browser then.

Now I'm using version 133.0.3, Firefox for Linux Mint mint-001 - 1.0. Yes, I realize this is not the current version. If it's possible to get this feature with the current version, I'll be happy to upgrade.

Thank you very much.

I went to my favorite web site this morning (dpreview/forums) and when it displayed I must have accidentally clicked some Firefox thing because the page was then overlaid with a thin orange highlight with the word PICK on it. I tried moving the cursor off the page but it only changed which segments of the page were highlighted. So I clicked and the page was replaced by just the menu section of the page, apparently that was what was highlighted when I clicked.

Now, no matter what I do, when I try to go to that url only the menu is displayed, the normal list of forums is missing. I've restarted FF. I've rebooted. I've cleared cookies and cache. I've refreshed the page. Nothing helps. Other web sites are fine. I can't imagine what this is for. A diagnostic tool or accessibility thing perhaps.

Please help. I'm running latest FF on latest Win 11.

I'm trying to setup a new laptop and when I try to log in I enter my password, I get my email with my 2 factor code, enter it and then it kicks me back to the password screen saying "Incorrect password" . I've reset the password a few times and still get the same behavior. Am I only allowed to have 1 device logged in at once? I know in the past I was able to have multiple computers logged in.

Now that Mozilla/Firefox have joined Google on the dark side, who is everyone switching to? I would like something that works well in both Windows and android. I hear Opera can't be trusted and I don't like how there are like 6 difference versions of Opera in the android app store. DuckduckGo is just badly made IMO. Edge causes some glitches with one of the sites I use most. Should I try Brave? I just want a browser to BROWSE the web. I don't want AI. I don't need a VPN or adblock built in. I don't want a "gamer" browser. A decent local password manager would be nice but I don't want to have to make an account to use it. I know if the product is free, you are the product, so I would almost prefer a browser you pay for but oddly that doesn't seem to be a popular option. Probably because the user data the companies collect makes them more money then people would be willing to pay. Sad times. I miss the 90's.
