I realize this is in a beta OS, but I imagine it'll need to be addressed at some point.

Anywho, when using vertical tabs, the left side expand/collapse button lives underneath the close, minimize, full-screen OS buttons.

First symptom: Lately, when I use Firefox on my desktop to attach a JPG or PNG screenshot to an online post, it shows up only as a black square. (The image looks normal while I'm creating the post, but it won't post - which I've confirmed by checking my feed on a different device.) This doesn't happen when I use the same version of Firefox (the latest one), also running Windows 10, on my laptop. It has nothing to do with the screenshot itself - the specific file or the file type; the same thing happens with anything I try to attach.

Second symptom: When I create a PDF with Firefox and then try to print it, a large rectangular portion at the top is blanked out, as if someone had placed a sheet of paper on top of it. This doesn't happen when I use Chrome to open and print the same document on the same computer.

My guess is that I've somehow changed one of the graphics or image settings in about:config, but I have no idea which one.

Any ideas would be greatly appreciated.

When I go to view an already open tab it will sometimes randomly move it to the very end of my tabs all the way to the right. I don't want it to move tabs without my intervention. Clicking on a tab should keep it in place.

This has been an issue for about 2 months now. I'm not sure what's causing it or even if it's entirely a Firefox issue as I have noticed something similar happen in another program with tabs that I use often. It still seems like a Firefox issue in that moving a tab all the way to the end is a very specific task that can't normally be done accidentally.

Is there a way to prevent this from happening or has anyone figured it out?

Why won't Firefox open any new windows? I give ir the command to open a window and yet all i get are tabs and I never click on open a tab. I have an HP probook this for windows 10 and i am also having the same problem with Chrome. I have uninstalled and reinstalled chrome and that did not fix it so it is not that. What would cause this? I have already cleared the cache cookies history browsing etc. and nothing is fixing it. PLEASE HELP.

I created a tab group and saved it. After saving I confirmed it was inn the toolbar location. I used it this morning successfully. Just now I closed all my tabs in order to shut down. Doing so eliminated the tab group. It is no longer available from the toolbar. What happened?

Is there a way of changing/removing the independence of browser windows?

Whenever I have multiple windows and close one them I cannot retrieve them, re-opening closed tabs doesn't work, since it only works on their own window.

Is there a way to change this behaviour?

I hope I have explained myself, thanks.

when I play a product video on amazon, I get the following error. I don't have a problem with another browser.

The media playback was aborted due to a corruption problem or because the media used features your browser did not support. this is a linux mint desktop.

thanks.

In particular, this is running Firefox 139.0.4 (64-bit) under Windows 10, and finding a huge file and activity here: C:\Users\Lab\AppData\Local\Mozilla\Firefox\Profiles\4wyhpro4.default\cache2\entries And, if I simply delete everything there, it seems like it regenerates fairly quickly, whether I've been using the browser or not. What are these strange entries, which look like this growing list:

Hello dear helpers, When I click on a webpage link (or right-click a link to open a tab in a container), Firefox repeatedly opens the same tab all across the tab line; maybe 20 or more of the same tab. I would be grateful for help if anyone knows how to solve this. Thanks, -AnneF

If I turn on "always use private surfing", can I not have shortcuts on my Firefox landing page?

I had six shortcuts on my landing page; however, I turned on "always be incognito", and my shortcuts disappeared, and I do not see an option to add them back.

Are they mutually exclusive? If not, how do I FIX THIS?

Recently I've noticed that my tabs auto refresh if I have'nt been in them for a while. I turned that off ages ago cus I hate it. Now, all of a sudden they refresh again.

accessibility.blockautorefresh services.sync.prefs.sync-seen.accessibility.blockautorefresh

Are both set to true, which I'm pretty sure was supposed to block auto refresh.

I don't know what else to do.

I'm on Firefox version 139.0.1 (64-bit), Windows 11.

Sunday, I reset my laptop back to factory settings. I reloaded Firefox and now cannot access the second level on Intuit's training website as it loads as a picture not a web site. I tried using MS Edge and also Chrome to see if the issue was with Firefox, but all have the same issue. I white-lighted all of the Intuit domains in pop-ups in case that was the issue, which it is not.

I'm using NORD VPN and ESET for viruses.

Does anyone have any ideas?
